-# mini-ork
-
-Task operating system for agents: classify → plan → execute → verify → reflect → improve.
-Heterogeneous-model recipe runner with cost governance, runtime verification, and a GRPO learning loop.
-
-This file is the canonical context map. Detail lives in `docs/`; procedural knowledge lives in recipe prompts under `recipes/<name>/prompts/`.
-
-## Map
-
-- **[docs/architecture](docs/architecture)** — system design and component diagrams
-- **[Artifact graph contracts](docs/architecture/artifact-graph.md)** — declared ports, run-local manifests, transforms, and visibility limits
-- **[docs/operator](docs/operator)** — running mini-ork, env vars, troubleshooting
-- **[recipes](recipes)** — available task recipes (`code-fix`, `bug-audit-cmgk`, `framework-edit`, …)
-- **[schemas](schemas)** — `task_class.schema.json`, `workflow.schema.json`, `artifact_contract.schema.json`
-- **[tests](tests)** — unit and e2e tests
-
-## Working in this repo
-
-- Entrypoint: `bin/mini-ork <subcommand>`
-- Python runtime is the only runtime (bash entrypoints removed in the 2026-07 bash-removal; see `docs/plans/2026-07-26-bash-removal-plan.md`).
-- Path contract: `mini_ork.context.RunContext` resolves `MINI_ORK_ROOT`/`MINI_ORK_HOME`/`MINI_ORK_DB` (formerly `lib/paths.sh`).
-- `mini-ork init` scaffolds `.mini-ork/` and writes a committed `.mini-ork/engine` pointer.
-
-## Dev loop — worktree first
-
-`main` stays clean: implementation work never happens in the main checkout. A
-`reference-transaction` guard (`.githooks/reference-transaction`) blocks direct
-feature-branch creation — branch through a worktree instead.
-
-```bash
-make worktree SLUG=<slug>            # new worktree + branch off origin/main
-#   … edit + commit inside the worktree …
-make worktree-merge SLUG=<slug>      # rebase origin/main → green-gate → push HEAD:main
-make worktree-clean SLUG=<slug>      # remove worktree + delete branch
-```
-
-- Worktrees live under `/Volumes/docker-ssd/ps/mini-ork-worktrees/<slug>`
-  (`MINI_ORK_WORKTREES_DIR` to override); branches are `wt/<slug>`.
-- `--owns <path>` claims a file surface (CAID registry); a second worktree whose
-  claim overlaps a live one is refused, so concurrent agents can't race a file.
-  `make worktree SLUG=x OWNS="mini_ork/foo.py tests/bar"`.
-- The green gate runs `python3 -m pytest -q` before pushing; scope it per-task
-  with `MINI_ORK_TEST_CMD` (e.g. a single parity gate for a fast merge).
-- Merge is `push HEAD:main` (no PR); never `reset --hard` or revert main.
-- One-time per clone: `make install-hooks` (activates `.githooks/`).
-
-## Quality gates (run before committing)
-
-```bash
-make test                    # existing test suite
-make lint                    # ruff blocking tier (F + E9; advisory: make lint-advisory)
-mini-ork validate            # pre-run static checks
-mini-ork garden              # drift detection
-```
-
-CI mirrors these: `.github/workflows/ci.yml` runs ruff (blocking + advisory
-tiers), pytest on 3.11/3.12 (sharded), UI typecheck, and web smoke;
-`.github/workflows/release.yml` re-runs the blocking lint + a unit-layer
-pytest smoke before building release artifacts.
-
-## Extension points
-
-- Recipes: add a directory under `recipes/` with `task_class.yaml`, `workflow.yaml`, `artifact_contract.yaml`.
-- Providers: add entries to `config/providers.yaml` and env vars to `config/secrets.local.sh`.
-- Gates: register an evaluator via `mini_ork.gates.gate_registry.register_gate_evaluator(type, fn)`.
-
-### Python runtime registries (SOLID refactor, 2026-07)
-
-The Python runtime exposes registration APIs so new behavior lands without
-editing executor core modules:
-
-- `mini_ork.context` — canonical `RunContext` env contract; mutate process env
-  only via `apply_env_overrides` / `scoped_environ`.
-- Node types: `mini_ork.cli.execute.register_node_handler(type, fn, phase=)`
-  (+ `register_implementer_submode` for fan-out dispatchers).
-- Routing policies: `mini_ork.dispatch.routing.register_policy(name, fn)`
-  (selected via `MO_ROUTING_POLICY`).
-- Gate types: `mini_ork.gates.gate_registry.register_gate_evaluator(type, fn)`.
-- Provider kinds / transports: `mini_ork.dispatch.providers.register_provider_kind`
-  / `register_dispatch_backend`.
-- Subcommands: `mini_ork.cli.main.register_subcommand(name, handler)`.
-- Embedders: `mini_ork.memory.semantic.register_embedder_provider(name, factory)`
-  (selected via `MO_EMBED_PROVIDER`).
-
-Executor concerns live in dedicated modules: lane routing in
-`mini_ork/dispatch/routing.py`, GRPO writeback in `mini_ork/learning/writeback.py`,
-publish gates + delivery in `mini_ork/cli/publisher.py`.

-## [0.7.0] - 2026-07-30
-
-**Native Python runtime.** MiniOrk now runs its framework runtime entirely in
-Python while retaining the public `mini-ork` command surface and its
-verifier-first execution model.
-
-### Added
-
-- Native extension registries for node handlers, routing policies, gate
-  evaluators, provider kinds/transports, subcommands, and embedders.
-- Declarative provider lanes in `config/providers.yaml`, including a native
-  Codex transport with usage and cost sidecars.
-- Native ContextNest hook bridge, migration runner, gate evaluation, and
-  Python compatibility launchers for legacy `mini-ork-*` commands.
-
-### Changed
-
-- Provider, gate, migration, launcher, tracing, recovery, learning, and
-  orchestration ownership now resolves through the supported Python runtime.
-- The release process now verifies the current Ruff, pytest, validate, and
-  garden gates before tagging.
-
-### Removed
-
-- The internal Bash runtime: `lib/`, framework gate scripts, runtime selection,
-  Bash-only test/CI layers, and Bash provider wrappers.
-
-### Migration note
-
-- Custom integrations must no longer source internal `lib/*.sh` or
-  `gates/*.sh` files. Use the public `mini-ork` CLI, recipe contracts, or the
-  documented native Python extension points. Existing recipe verifier and
-  sandbox command boundaries continue to support shell commands where declared.

 # mini-ork
 
-**A task operating system for AI agents — one that makes them prove their work.**
-
-mini-ork turns a goal into a planned, executed, and *verified* run across a fleet of
-different models: **classify → plan → execute → verify → reflect → improve**. The
-verdict on every change is what the code **actually did when it ran** — tests, type
-checks, schemas, real execution in an isolated sandbox — not a model's opinion of its
-own output.
-
-It is for teams who want an agent to do real work without treating fluent output, a
-green-looking diff, or a panel of agreeing models as proof.
-
-## Why this exists
-
-AI agents now write code faster than any team can review it. The bottleneck moved from
-*generation* to *validation*. An agent that writes its own tests and then grades itself
-produces output that agrees with itself — fluent, green-looking, and wrong often enough
-to break production. And the naive fix (send everything to a frontier model, run it many
-times) makes the bill grow faster than the unit price falls.
-
-mini-ork is built for the world *after* "make it generate": ship agent work you can
-trust, at a cost you can defend, on a system that gets sharper on your codebase the more
-you run it.
-
-**Why now:**
-
-- **Reliability is the new bottleneck.** 81% of enterprise technology leaders report an
-  *increase* in production issues linked to AI-generated code (CloudBees,
-  [*2026 State of Code Abundance Report*](https://www.theregister.com/ai-ml/2026/05/20/ai-code-boom-drives-production-failures-higher-spending/)).
-- **Cost routing is a real lever.** Routing between a strong and a weak model can cut cost
-  **more than 2×** without compromising quality
-  ([RouteLLM, arXiv:2406.18665](https://arxiv.org/abs/2406.18665)) — the lever mini-ork
-  automates, but conditioned on a verification bar rather than a guess.
-- **Pilots stall on the same three things.** Most agent pilots don't reach production, and
-  the blockers are consistently evaluation, reliability, and governance — the three layers
-  mini-ork treats as runtime primitives instead of afterthoughts.
-
-## Three things an orchestration framework won't do for you
-
-Wiring agents into a graph is now commodity (LangGraph, CrewAI, AutoGen). mini-ork adds
-the three layers that decide whether agent work is actually *shippable*.
-
-### 1. It verifies correctness — it doesn't just orchestrate
-
-The source of truth for a change is its **execution outcome**, captured in an isolated
-runtime (mini-ork's `Crucible`, over Prime Intellect's MIT-licensed `verifiers`):
-
-- **Execution-anchored reward.** A change is scored on what it *did* — did the test run,
-  did the assertion pass — not on a reviewer's approval. An LLM judge may only **veto** a
-  passing result, never fabricate a passing one (`reward_from_status`,
-  `mini_ork/learning/writeback.py`).
-- **A real failure ≠ a broken harness.** The runtime distinguishes a genuine assertion
-  failure (a real reproduction) from a broken test or a broken environment, so a correct
-  patch is never rejected because the *probe* had a typo.
-- **Non-regression is certified.** Candidates that would break a previously-solved,
-  held-out task are blocked before they ship (per-task no-regression gate,
-  `mini_ork/cli/apply.py`).
-- **A run with no meaningful check is reported as *vacuous*,** not silently successful.
-
-### 2. It governs cost across a pool of models
-
-You don't pay frontier prices for work a cheaper model can pass:
-
-- **Heterogeneous dispatch.** Bring your own providers (OpenAI/Codex, MiniMax, Kimi, GLM,
-  Anthropic, or any OpenAI-compatible endpoint) and route each node to a lane by role.
-- **Cost-optimizing routing policies.** Selectable strategies from `frontier_only` to
-  `cheap_only` to `learning_governed` — route to the cheapest lane that still clears the
-  verification bar (`MO_ROUTING_POLICY`).
-- **Hard cost controls.** A daily-spend circuit breaker, a periodic cost-pause sentinel
-  an operator must approve, and a wall-clock deadline budget — so an autonomous run can't
-  quietly burn your account.
-
-### 3. It learns from what actually verified
-
-Every run leaves a trail of *verified* outcomes, and the system feeds that signal back:
-
-- **Cost-free contextual-bandit routing** adjusts which lane gets each role next time,
-  from real advantage — no extra model calls (`mini_ork/lane_router.py`).
-- **GRPO group-relative writeback** and **textual-gradient** prompt evolution improve the
-  planner / implementer / reviewer prompts across runs.
-- **Verified-outcome memory** persists *only what passed the gates*, so the learned
-  signal is clean rather than noise. A closed **learn → apply** loop materializes,
-  scores, and non-regression-gates each proposed improvement before it lands.
-
-## Where it fits
-
-mini-ork isn't a prettier agent graph or a cheaper autonomous coder. Orchestration
-frameworks wire agents together; coding products write and ship; eval tools score after
-the fact. mini-ork is the open-source runtime where **correctness is the primitive**:
-every run yields a verified outcome, that outcome routes the next run to a cheaper model,
-and the signal compounds on *your* repository.
-
-That specific combination — correctness-conditional, cost-optimizing, compounding, and
-open-source — is the wedge, and it doesn't exist together anywhere else today.
-
-Honest about the edges: the execution oracle is only as strong as what you can *run*, so
-its guarantees are richest on code with real tests and thinnest on subjective or
-untestable work — where mini-ork is designed to surface uncertainty or ask a person
-rather than manufacture confidence.
-
-## What is in the box

+
+> **Motto:** Stop drawing agent graphs that let one model family grade its own homework. mini-ork turns goals into verifier-gated, stateful, cross-family agent runs, so teams get durable artifacts instead of same-vendor consensus theater.
+
+mini-ork is a **task operating system for agents**. It receives a goal, classifies the work, chooses a workflow, dispatches specialized agents across *distinct model families*, verifies artifacts deterministically, and stores execution experience so every run starts smarter — and cheaper — than the last. It does NOT ship opinions on what your pipeline should look like: pipeline shapes live in [`recipes/`](./recipes/) as composable user-land examples.
+
+> ⚡ **30-second demo (no API keys):** `bash examples/00-demo.sh` — bootstraps a throwaway project, walks the classify → plan → execute → verify loop in dry-run mode (no LLM calls), prints the dispatched node sequence + the plan path that *would* be written. Set `MINI_ORK_DRY_RUN=0` to fire real LLM calls and populate the `task_runs` row.
+
+📖 **Full feature catalog:** [docs/FEATURES.md](docs/FEATURES.md) — every capability, pinned to the code that implements it.
+
+---
+
+## Competitive advantage: compounding agent work, not one-off prompting
+
+mini-ork's edge is that it treats agent work as an operating system problem, not a chat-session problem. The framework records what happened, routes the next attempt through better lanes, verifies outputs with executable gates, and can improve its own workflows under budget and safety constraints.
+
+| Advantage | Why it matters | How mini-ork implements it |
+|---|---|---|
+| **Recursive self-improvement** | The system can learn from its own failed or expensive runs instead of waiting for a human to manually redesign the workflow. | `recursive-self-improve` scans bottlenecks, gathers heterogeneous evidence, proposes workflow/code changes, benchmarks them, and promotes only through gated checks. The 2026-06-09 run produced 10 autonomous, evidence-cited commits to `main`. |
+| **Cross-family review independence** | A panel of same-family agents often shares the same blind spots; diversity only counts when the evaluators are meaningfully different. | Recipes can dispatch lenses across Zhipu, Moonshot, OpenAI, DeepSeek, Anthropic, and MiniMax lanes, while `coalition_gate.sh` blocks same-family degeneration. |
+| **Executable verification before opinion** | LLM review is useful, but it should not be the final oracle when tests, schemas, or shell checks can decide. | Recipe-local `verifiers/*.sh` return mechanical pass/fail results; empty verification is marked `vacuous`, not silently treated as success. |
+| **Persistent memory and trajectory data** | Each run becomes training signal for the next run without fine-tuning a model or depending on hidden vendor memory. | `state.db` stores task runs, failure gradients, context packs, agent performance, cost, duration, and lineage. Planner/node prompts receive relevant prior outcomes. |
+| **Cost-aware orchestration** | Agent systems fail in production when every step uses the most expensive model or runaway loops keep billing. | Lane routing, per-call `llm_calls`, `MO_DAILY_BUDGET_USD`, per-run budgets, cache reuse, escalation edges, and circuit breakers make spend visible and bounded. |
+| **Recipes instead of framework lock-in** | Teams need different workflows without forking the orchestrator. | Domain logic lives in `recipes/`; the framework supplies the reusable classify → plan → execute → verify → reflect → improve loop and the shared safety rails. |
+
+The practical result: mini-ork can start cheap, escalate only when gates fail, preserve what it learned, and recursively improve the workflow that produced the result. That is the difference between a capable agent session and a compounding agent system.
+
+---
+
+## Why not just a single-agent coder?
+
+Single-agent coding assistants are remarkable engines. They are also, structurally, three bad deals at once:
+
+| The single-agent deal | What it costs you | What mini-ork does instead |
+|---|---|---|
+| **Amnesia.** Every session starts from zero. | You re-pay the model to re-learn your codebase, your conventions, and the failure it hit yesterday — every single session. | `state.db` persists execution traces, failure gradients, and outcomes. The planner prompt receives the last 5 same-class runs (cost, failures, duration). Yesterday's lesson is today's context. |
+| **Self-grading.** The same model family writes the code *and* approves it. | Review theater: a panel of four Sonnets is one disposition amplified four times (measured: Krippendorff α = 0.042 across judge families). Bugs that family is blind to stay invisible. | Review lenses dispatch to **distinct vendors** (Zhipu, Moonshot, OpenAI, DeepSeek, Anthropic, MiniMax) by configuration, then deterministic `verifiers/*.sh` decide pass/fail mechanically. |
+| **Unmetered spend.** One frontier-priced model for every token, no ledger, no breaker. | Routine grep-level checks billed at architecture-review prices; runaway loops discovered on the invoice. | Per-call `llm_calls` ledger, a dispatch-enforced daily cost cap ($50 default) plus per-lane dispatch budgets, cost + behavioral circuit breakers, and cheap-lane routing — frontier models only where judgment is actually needed. |
+
+The rest of this README is those three rows, with receipts.
+
+---
+
+## The economics: route by price, verify for free, cap the rest
+
+**Cheap-lane routing.** A workflow node declares a *role*; config maps roles to model families. Tactical checks run on budget families, frontier models are reserved for synthesis:
+
+```yaml
+# config/agents.yaml — the shipped defaults, post cost audit (v0.2-pt8)
+lanes:
+  planner:  sonnet   # was opus — audit downgrade: ~$12-18K/day saved at 100K-run scale
+  worker:   sonnet
+  verifier: sonnet
+  reviewer: opus     # kept frontier — final verdict quality
+```
+
+**Deterministic verification costs zero tokens.** Every recipe ships `verifiers/*.sh` — pass/fail is an exit code, not an LLM opinion. You don't pay a model to decide what a test suite can decide. When zero verifiers execute, the verdict is `vacuous`, never success — "nothing was checked" is not laundered into a pass.
+
+**Every call lands in a ledger.** The `llm_calls` table records model, tokens, cost, duration, and session per dispatch — token totals taken from the billed result envelope, not client-side guesses:
+
+```bash
+sqlite3 .mini-ork/state.db \
+  "SELECT model_id, COUNT(*), ROUND(SUM(cost_usd),2) FROM llm_calls GROUP BY model_id;"
+```
+
+**Caps and breakers, not hope.** A daily cost cap is enforced inside the dispatcher itself (`MO_DAILY_BUDGET_USD`, $50 default) — over-budget calls are refused, and the self-improve runner re-checks the same cap *before* each iteration spins up. Per-epic / per-run budget defaults ($5 / $0.50) are declared in `config/agents.yaml` and surfaced to every dispatch as per-lane budget flags. A behavioral circuit breaker ([`lib/circuit_breaker.sh`](lib/circuit_breaker.sh)) detects cost-burn-without-write, artifact stagnation, and stuck verdicts — spinning runs get killed, not billed. [`lib/throttle-guard.sh`](lib/throttle-guard.sh) backs off throttled providers per-lane instead of retry-storming.
+
+**Start cheap, escalate only on failure.** Escalation is modeled, not improvised: `escalates_to` edges in the workflow DAG fire only when a gate actually fails, and every agent definition declares a `fallback_above` precision ladder that terminates at opus ([`config/README.md`](config/README.md)) — the expensive model is the exception path, not the default. Stage-level memoization ([`lib/cache.sh`](lib/cache.sh)) and a cheap 8-item rubric pre-screen ([`lib/rubric-prescreen.sh`](lib/rubric-prescreen.sh)) cut repeat and pre-test spend further.
+
+---
+
+## The learning loop: runs that compound
+
+A single-agent session is a goldfish. mini-ork closes the loop:
+
+```
+run → trace (cost, files, tools, lineage)
+    → reflect (LLM extracts "textual gradients": what to do differently)
+    → inject (planner + node prompts receive prior outcomes & failure modes)
+    → improve (workflow candidates → benchmark → gated promotion, with rollback)
+```
+
+Concretely:
+
+- **Prior-run memory injection** — the planner sees the last 5 same-class runs: which nodes failed, what they cost, how long they took. Plans calibrate against history instead of repeating it.
+- **Learned-failure-mode injection** — high-confidence gradients are injected into node prompts at dispatch time. The mistake from run 12 is a warning label in run 13.
+- **Auditable context packs** — the exact memory bundle available at plan time is persisted next to the plan (`context-pack.json`). You can audit what the planner knew.
+- **Agent performance history** — success rate, cost, latency accumulate per agent version in `agent_performance_memory`. Dispatch gets data, not vibes.
+
+**Receipts:** the [self-improvement session below](#recursive-self-improvement-evidence-2026-06-09-session) ran this loop against mini-ork itself — 10 autonomous, evidence-cited commits to `main` in ~5 wall-clock hours, including the loop finding and fixing bugs by reading its own prior run logs.
+
+Measure your own trajectory any time:
+
+```bash
+mini-ork metrics --recipe refactor-audit   # cost trend, wall-time trend, gradient yield
+```
+
+---
+
+## Why heterogeneous-family multi-agent (the load-bearing claim)
+
+**Most agent frameworks ship multi-agent review where every agent is the same model family.** That's the [evaluative coalition](https://blog.sourceshift.io/p/we-ran-a-3-source-bug-hunt-then-we-realised-our-validators-were-all-claude) failure mode the literature has now named, measured, and assigned harshness coefficients to. A panel of four Sonnets isn't four independent judges — it's one disposition amplified four times.
+
+mini-ork is built around the opposite prior: **dispatch lenses to distinct model families by configuration.** The literature below does not prove that vendor diversity alone is sufficient; it supports a narrower, more useful design rule: multi-agent review needs low-correlation evidence channels, executable checks, and information boundaries. mini-ork uses model-family diversity as an enforceable proxy for that independence, then adds deterministic verifiers where possible.
+
+### Research signals behind the design
+
+| Paper | What it supports |
 |---|---|
-| **Orchestration core** | Full `run` lifecycle, keyword task classifier, planner with repair-on-bad-JSON, recovery DAG, a multi-epic scheduler, and a meta-policy conductor. |
-| **Heterogeneous model dispatch** | BYO provider registry (5 kinds), 6 routing policies, role-aware fallback chains, per-provider throttle guards, and an owner-only secrets store. |
-| **Runtime reliability** | Durable-DAG resume (resurrect a failed run at the step or turn), single-writer leases + fencing, idempotent tool receipts, and cost/deadline circuit breakers. |
-| **Verification & gates** | An extensible gate registry (deterministic verifiers, reviewer/human/budget/scope gates), evidence-cited grounded rejections, and promotion gated on measurable evidence. |
-| **Self-improvement & learning** | Anti-Goodhart reward contract, cost-free bandit router, GRPO writeback, reflection pipeline, semantic long-term memory, and a closed apply loop. |
-| **Observability surface** | A FastAPI app (127.0.0.1:7090) with an SSE live event stream, run detail + DAG overlay, a "why did this fail" aggregator, learning dashboards, and OTel/Langfuse export. |
-| **Operator & dev ergonomics** | A stable CLI — `init`, `run`, `validate`, `doctor`, `providers`, `garden`, `serve`, `recover` — plus worktree-aware, file-surface-leased workflows for safe concurrent agents. |
-
-## Start here
-
-`make install` installs the supported local runtime: required OS tools, a checkout-local
-`.venv`, the `.[full]` Python profile (CLI, local web sidecar, and Crucible), and the
-per-user `mini-ork` command. Dry runs do not call a model provider. Real runs
-additionally need the provider CLIs or provider configuration selected by your lanes.
-
-~~~bash
-# Get mini-ork and install the full runtime (macOS, Linux, or WSL).
-git clone https://github.com/SourceShift/mini-ork.git
-cd mini-ork
-make install
-
-# Open a new terminal if the installer changed PATH, then confirm it uses .venv.
-mini-ork version
-~~~
-
-On native Windows PowerShell, install the OS prerequisites with `winget` first
-(`Python.Python.3.11`, `Git.Git`, `jqlang.jq`, `MikeFarah.yq`, and `SQLite.SQLite`), then
-run this from the checkout:
-
-~~~powershell
-py -3 .\scripts\full_install.py
-mini-ork version
-~~~
-
-`make install` is safe to re-run after an upgrade. It reuses `.venv`, updates the
-editable package, repairs the managed command, and verifies the OS tools. Use
-`INSTALL_SYSTEM_DEPS=0` only when those tools are already managed outside mini-ork. Use
-**mini-ork install --help** to see **--bin-dir**, **--no-path**, **--force**, and
-**--dry-run** for the command-only installer.
-
-### Your first verifier-backed workflow
-
-Start in a real Git repository. Keeping the mini-ork checkout path lets you copy its
-example into the project you want to work on.
-
-~~~bash
-# In the mini-ork checkout, remember its location before leaving it.
-MINIORK_SOURCE="$PWD"
-
-# Make a small project to try it on.
-mkdir -p ~/miniork-demo && cd ~/miniork-demo

+7 model-family wrappers ship out of the box at [`lib/providers/`](lib/providers/): `cl_{glm,kimi,codex,deepseek,opus,sonnet,minimax}.sh`. The audit recipe at [`recipes/refactor-audit/`](recipes/refactor-audit/) uses all 4 distinct lens families per cycle (glm + kimi + codex + opus). MiniMax is available as an opt-in additional family for recipes that can afford a 5th lens.
 
-## Use mini-ork well
+**Bring your own keys:** no wrapper needed to add a provider. Declare Anthropic or OpenAI-compatible endpoints in [`config/providers.yaml`](config/providers.yaml) (`kind: anthropic-native | anthropic-compat | openai-compat | executable`), put the key in `.mini-ork/config/secrets.local.sh` (template: [`config/secrets.example.sh`](config/secrets.example.sh)), and point an `agents.yaml` lane at the entry. A `cl_<name>.sh` wrapper always wins over a registry entry of the same name, so registry entries can't change builtin behavior. Details: [docs/CONFIG.md](docs/CONFIG.md) → "Bring-your-own providers".
 
-1. **Write a verifiable kickoff.** State the target repository, allowed files, intended
-   artifact, and the command or rule that proves success.
-2. **Dry-run every new recipe or environment first.** It checks the lifecycle and
-   artifact paths without model calls; it does not prove the eventual change is correct.
-3. **Give an agent an oracle when you can.** Prefer an existing test, typecheck, schema,
-   fixture, or observable acceptance criterion over an LLM-only score.
-4. **Use multiple lenses deliberately.** Heterogeneous review is useful for discovery and
-   diagnosis; it does not replace deterministic verification.
-5. **Read the evidence before promotion.** mini-ork retains traces and can learn from
-   runs, but automatic promotion is intentionally restricted to classes with measurable
-   external evidence.
+And the panel quality is *instrumented*, not assumed: a pre-synthesis coalition gate ([`lib/coalition_gate.sh`](lib/coalition_gate.sh)) hard-blocks same-family degeneration, panel topology telemetry ([`lib/topology_metrics.sh`](lib/topology_metrics.sh)) measures realised correlation per run, and the observability UI's `/fingerprint` route shows exactly which family ran which lens.

+### How it compares to Claude Code / OpenAI Agents SDK / LangGraph dynamic workflows
+
+| Axis | Single-vendor agent SDKs | mini-ork |
+|---|---|---|
+| Agent diversity | Within-vendor configurability (Claude subagent model selection, LangGraph model-agnostic nodes) but no framework-enforced cross-family separation | 7 families configurable per lane + `lib/coalition_gate.sh` hard-blocks same-family degeneration |
+| State persistence | Per-session by default; project-scoped memory is opt-in and shallow (Claude Code CLAUDE.md, OpenAI Sessions, LangGraph checkpointer) | `state.db` (SQLite) across runs — task_runs, gradients, lineage, agent_performance_memory, run_events, llm_calls |
+| Cost governance | Vendor-side observability (LangSmith usage, OpenAI usage API, Claude cost dashboards) — visible but not dispatch-enforced | Per-call ledger + dispatch-enforced caps (`MO_DAILY_BUDGET_USD`) + per-lane budgets + circuit breakers — over-budget calls refused, not billed |
+| Trajectory measurement | Vendor-scoped traces (LangSmith, OpenAI Traces, Claude Code session telemetry) — span-level but not cross-cycle aggregate | `mini-ork metrics` cross-cycle — gradient yield, relative-advantage per agent, cost+dur trends, lane utilization |
+| Executable specification | Model decides what's good | `verifiers/*.sh` deterministic gates |
+| Self-publishing | Output stays in session log | Publisher node `git commit` under `mini-ork@local` |
+| Cross-cycle improvement | Memory persists across sessions (Claude memories, LangGraph memory modules, OpenAI memory) but added monotonically — no gating, rollback, or versioned promotion | reflect → improve → eval → promote chain — gated by utility-delta + benchmark, with quarantine + rollback via `version_registry` |
+| Reproducibility | Same kickoff can be replayed (LangGraph checkpointer, Claude Code session resume, OpenAI Sessions) but the framework does not instrument run-to-run variance | Deterministic given same kickoff; where variance exists (epsilon-greedy routing, LLM sampling) the trajectory is captured in `state.db` |
+
+**Composition, not competition:** mini-ork dispatches Claude Code, codex, gemini-cli, GLM, Kimi etc as worker agents. The framework is the operating system; the vendor SDKs are the engines.

-## Honesty by design
+## Quickstart
 
-mini-ork does **not** claim a universal oracle. Where there is no trustworthy external
-check — a subjective product decision, untestable code — it should surface uncertainty or
-ask a person rather than manufacture confidence. That discipline is wired in, not aspirational:
+### Prerequisites — provider CLIs
 
-- A run whose verification is absent or meaningless is reported as **vacuous**.
-- The dispatch and learning surfaces refuse to invent a number below their evidence
-  threshold (Wilson-CI honesty: `<5` samples returns `evidence: "none"`).
-- Every gate rejection cites the evidence trace it was based on, so a "no" is auditable.
+mini-ork dispatches agents through vendor CLIs, not raw API keys. Install and
+authenticate the CLIs for the model families your lanes use:
 
-## Learn more
+| CLI | Model families it unlocks | Install | Authenticate |
+|---|---|---|---|
+| [`claude`](https://docs.anthropic.com/en/docs/claude-code) | Anthropic (sonnet/opus lanes) **and** Anthropic-compatible gateways (GLM, Kimi, DeepSeek, MiniMax via `lib/providers/cl_*.sh` env pinning) | `curl -fsSL https://claude.ai/install.sh \| bash` or `npm i -g @anthropic-ai/claude-code` | `claude` (interactive login) |
+| [`codex`](https://github.com/openai/codex) | OpenAI (codex lane, `codex_lens` reviews, BYO OpenAI-compatible endpoints) | `npm i -g @openai/codex` | `codex login` |
 
-Read the [architecture](docs/ARCHITECTURE.md), [operator guide](docs/operator),
-[safety model](docs/SAFETY.md), and [feature inventory](docs/reference/FEATURE-INVENTORY.md)
-when you need the detailed contracts.
+`claude` is required for any real run with the default lane config (planner /
+worker / verifier / reviewer all route through it). `codex` is only needed when
+a recipe assigns the `codex` lane or `codex_lens` — without it those nodes fail
+at dispatch. Dry-run mode (`MINI_ORK_DRY_RUN=1`) needs neither.
+
+> Keep the CLIs current (`claude update`, `npm i -g @openai/codex@latest`) —
+> the dispatcher uses newer CLI flags (e.g. prompt-cache control), and old
+> binaries shadowed earlier in `$PATH` are a classic source of dispatch failures.
+
+```bash
+# 1. Install (creates symlink in $HOME/.local/bin or /usr/local/bin)
+bash install.sh
+
+# 2. Initialize a project (creates .mini-ork/ + seeds state.db + task_classes)
+cd ~/my-project
+mini-ork init
+
+# Later, refresh schema and inspect local config drift after framework updates
+mini-ork update
+
+# 3. Write a kickoff (or copy an example)
+cp <path-to-mini-ork-checkout>/examples/01-hello-world/kickoff.md ./kickoff.md
+
+# 4. Run from a kickoff (dry-run first, no API keys needed)
+MINI_ORK_DRY_RUN=1 mini-ork run ./kickoff.md
+
+# Or force a recipe explicitly
+MINI_ORK_DRY_RUN=1 mini-ork run code-fix ./kickoff.md
+
+# 5. For real LLM calls (needs `claude` CLI authenticated)
+mini-ork run ./kickoff.md
+```
+
+`mini-ork run` exits 0 on verified artifact, 1 on gate failure or escalation. All state is in `${MINI_ORK_DB}` (default: `.mini-ork/state.db`). Inspect with:
+
+```bash
+sqlite3 .mini-ork/state.db "SELECT id, task_class, recipe, status, verdict FROM task_runs ORDER BY created_at DESC LIMIT 5;"
+```
+
+### Observability UI (optional)
+
+A read-only React SPA backed by FastAPI exposes the same `state.db` + run
+artifacts as a browseable surface — fleet view, per-run DAG forensics,
+trajectory metrics, and the **detection-fingerprint** panel that audits
+which model families ran which lens per recipe.
+
+```bash
+# 1. Install backend + UI deps (one-time)
+make web-deps
+
+# 2. Boot the local UI (binds 127.0.0.1:7090, read-only)
+mini-ork serve
+
+# 3. Browse to http://127.0.0.1:7090
+```
+
+The SPA bundle ships under `mini_ork/web/static/` after `make web-build`.
+For dev with hot reload, run `make web-up` (FastAPI on :7090 + Vite on :7070), then open `http://localhost:7070`.
+Routes: `/` fleet, `/runs/:id` forensics, `/trajectory` convergence, `/fingerprint` coalition audit.

+## What ships in the framework vs. what lives in recipes
+
+### FRAMEWORK — zero opinions on pipeline shape
+
+The framework ships the universal loop and its primitives. Nothing in `lib/` or `bin/` knows about your domain.
+
+| Primitive | Location | Purpose |
+|---|---|---|
+| Universal loop | `bin/mini-ork-{classify,plan,execute,verify,reflect,improve}` | 6-stage lifecycle |
+| 8 node-type interfaces | `schemas/workflow.schema.json` + `bin/mini-ork-execute` | planner / researcher / implementer / reviewer / verifier / reflector / publisher / rollback |
+| Agent version registry | `lib/agent_registry.sh` | per-role agent versions (model, provider, tools, success_rate, known_failure_modes) |
+| 6 edge-type semantics | `schemas/workflow.schema.json` | depends_on / supplies_context_to / verifies / blocks / retries / escalates_to |
+| 7 built-in gate types + `custom` | `lib/gate_registry.sh` | deterministic_verifier / reviewer_gate / human_gate / budget_gate / scope_gate / deployment_gate / liveness_gate + `custom` escape hatch |
+| Behavioral circuit breaker | `lib/circuit_breaker.sh` | three orthogonal stagnation signals (artifact-hash invariance / verdict-stuck / cost-burn-without-write) with CLOSED→OPEN→HALF_OPEN state machine. Behavioral complement to the `MO_DAILY_BUDGET_USD` cost-CB (v0.2 Phase D) |
+| 8 memory namespaces | `db/migrations/` | task / workflow / agent_performance / failure / recovery / user_preference / artifact / benchmark |
+| Task-class registry | `${MINI_ORK_HOME}/config/task_classes/*.yaml` | typed task definitions |
+| Workflow registry | `recipes/<recipe>/workflow.yaml` | versioned DAGs |
+| Benchmark suite | `lib/benchmark_suite.sh` | eval harness |
+| Promotion gate | `lib/promotion_gate.sh` | utility_delta + benchmark gate |
+| Version registry | `lib/version_registry.sh` | promote / quarantine / rollback |
+| Group evolver | `lib/group_evolver.sh` | workflow candidate generation |
+| Experience memory | `lib/trace_store.sh` + `lib/gradient_extractor.sh` + `lib/pattern_store.sh` | store, extract, surface |
+| Recursive orchestration | `bin/mini-ork-spawn` + `lib/recursive_orchestration.sh` | bounded parent/child mini-ork delegation with lineage, events, and policy limits |
+
+### RECIPES — opinions live here
+
+Recipes are user-land workflow definitions. They compose framework primitives into pipeline shapes. 28 recipes ship today; 8 of them dispatch a 4–5 lens panel across distinct model families per cycle, using family diversity as a practical proxy for the low-correlation detector patterns highlighted by Rajan 2025.
+
+| Recipe | Location | Shape |
+|---|---|---|
+| `code-fix` | `recipes/code-fix/` | Single-patch fix with typecheck, test, and reviewer gates. Minimal reference recipe. |
+| `bdd-first-delivery` | `recipes/bdd-first-delivery/` | BDD-first multi-epic delivery: decompose → parallel (spec_author + implementer) → bdd_runner → reviewer → publisher. |
+| `docs` | `recipes/docs/` | Single-doc edit verified by grep-pattern assertions + relative-link integrity. No typecheck / test / rollback (docs edits are reversed via `git restore`). |
+| `refactor-audit` | `recipes/refactor-audit/` | 4 lens stances run in parallel (glm/kimi/codex/opus), with Opus preserved as the architectural-shape lens. The framework's own self-audit recipe. |
+| `research-synthesis` | `recipes/research-synthesis/` | 4-lens research synthesis (web/lit/code/narrative on distinct families) → synthesizer → publisher. |
+| `post-mvp-delivery` | `recipes/post-mvp-delivery/` | Discovery-first post-MVP product delivery: parallel product/architecture/integration/validation research → options for user choice → selected-option gate → implementation. |
+| `recursive-self-improve` | `recipes/recursive-self-improve/` | Wall-clock-budgeted self-improvement loop for mini-ork itself: bottleneck scan + heterogeneous lenses + arXiv evidence lane + synthesis + gated patch. Outer driver: `bin/mini-ork-self-improve`. |
+| `blog-post` | `recipes/blog-post/` | 5-lens blog drafting (editor / researcher / narrative / audience / counter) in parallel across distinct families. |
+| `db-migration` | `recipes/db-migration/` | 5-lens migration audit + plan: integrity / rollback / perf / compat / edge-data in parallel across distinct families. |
+| `ops-runbook` | `recipes/ops-runbook/` | 5-lens runbook generation: detection / containment / diagnosis / recovery / prevention across distinct families. |
+| `ui-audit` | `recipes/ui-audit/` | 5-lens UI audit: a11y / perf / visual / interaction / edge-cases across distinct families. |
+| `obs-smoke` | `recipes/obs-smoke/` | Cheap 2-node observability smoke (researcher + reviewer + deterministic verifier + publisher) that touches every emit surface: `llm_calls`, `run_events`, `task_runs` transitions. Driven by `tests/test_obs_surface.sh`. |
+| `recipe-creator` | `recipes/recipe-creator/` | Meta-recipe: takes a natural-language epic and produces a complete `recipes/<derived>/` directory via a 3-family drafter panel (glm/kimi/codex) + opus arbiter + verifier-smith + HARD heterogeneity-floor validator. The framework dogfooding itself on small-N recipe authoring. |
+| `silent-catch-audit` | `recipes/silent-catch-audit/` | **First recipe authored by `recipe-creator`** (run 1781087711, 2026-06-10). 3-lens audit of TS/JS codebases for silent `.catch(() => {})` anti-patterns — structural (codex) + semantic (glm) + adversarial (kimi) lenses → tiered findings reviewer with critical/high/allowed verdict. |
+| `framework-edit` | `recipes/framework-edit/` | **Recipe-creator-authored, 2026-06-11.** Routine mini-ork self-modification: planner → code-impact + prior-art lenses → glm implementer → static-check + test verifiers → opus reviewer → publisher / rollback. 4 distinct LLM families. Emits a unified diff for operator review; does NOT auto-apply. Mandatory dispatch path for every 2+ file change in this repo. |
+| `blog-cohesion` | `recipes/blog-cohesion/` | Multi-lens cohesion audit for long-form blog drafts. 5-LLM-role pipeline: GLM thesis check + parallel Sonnet reviewers (entity / bridge / rhythm / topic) → Opus arbiter. |
+| `feature-inventory-cmgk` | `recipes/feature-inventory-cmgk/` | Refactor-audit variant tuned for feature inventory passes — enumerates capabilities + where they're pinned in code. 4 distinct family lenses (codex / glm / kimi / minimax) → synthesis. |
+| `bug-audit-cmgk` | `recipes/bug-audit-cmgk/` | Refactor-audit variant tuned for bug enumeration with file:line anchors and severity tiers. 4 distinct family lenses → synthesis. |
+| `bug-audit-fe-be` | `recipes/bug-audit-fe-be/` | FE+BE bug audit: 2 heterogeneous lenses in parallel (kimi contract-violation + minimax user-impact) → opus synthesis ranks findings. |
+| `chapter-review` | `recipes/chapter-review/` | Multi-axis panel review of a book chapter by 4 heterogeneous LLM lenses. Produces a structured `chapter-review.json` with 9 axis scores. |
+| `researcher-qdrant-contract` | `recipes/researcher-qdrant-contract/` | PG/Qdrant indexing and retrieval contract remediation. Maps every content creation path to its canonical sync point. |
+| `schema-judge-panel` | `recipes/schema-judge-panel/` | Five-lens read-only judge panel for database/codebase architecture plans. Two Opus lenses plus Kimi, Codex, MiniMax. Each judge discovers, critiques, then proposes a migration plan. |
+| `epic-runner` | `recipes/epic-runner/` | **Recipe-creator-authored, 2026-06-12.** Multi-epic delivery orchestrator. Ingests a markdown epic doc with a dependency graph, walks it in topological waves, dispatches each epic as a child framework-edit run, aggregates verdicts, emits one gated delivery report. Dispatcher↔aggregator loop emulated inside the dispatcher node so the workflow DAG stays acyclic. |
+| `doc-to-features-loop` | `recipes/doc-to-features-loop/` | Document-driven feature extraction loop. Parses a long-form spec into discrete technical features, then iterates implementation + verification per feature with cross-feature dependency tracking. |
+| `recursive-validate-impl` | `recipes/recursive-validate-impl/` | **Recipe-creator-authored, 2026-06-12.** Recursive implement → multi-tier-validate → reflect → replan loop for any technical-feature kickoff. 5-tier verification (compile/typecheck → scoped unit → property + mutation → heterogeneous LLM panel) gated left-to-right; tier-4 panel cross-references implementation against arxiv-search-tool "modern techniques" compliance, not just done-state. Reflector extracts failure gradients; recursion hard-caps at 5 iterations or $25 with a divergence-kill safety net. |
+
+| `harness-bridge` | `recipes/harness-bridge/` | **2026-06-14.** Wraps a full coding-agent harness (claude-code / codex-cli / gemini-cli) as a workflow node. Harvey-pattern composition. Planner picks the harness from a kickoff declaration; harness-shape verifier checks the emitted diff applies. |
+| `chapter-validation-10lens` | `recipes/chapter-validation-10lens/` | **2026-06-15.** 10 parallel lens agents each judge ONE slice of chapter validation (structure, factuality, voice, length, forbidden constructs, format, coverage, coherence, reader contract, synthesis originality); a synthesizer rolls the 10 verdicts into one pass/revise/block call; a publisher emits a human-readable report. |
+| `mo-vs-omnigent` | `recipes/mo-vs-omnigent/` | Head-to-head comparison of mini-ork against the open-source [omnigent](https://github.com/omnigent-ai/omnigent) project across 4 distinct lens families (web / lit / code / narrative) → synthesizer. Demonstrates the heterogeneous-family pattern applied to competitive analysis. |

+
+---
+
+## 4 Extension Points
+
+Extensions do not require forking the framework. See [docs/EXTENSION.md](docs/EXTENSION.md) for full examples.
+
+1. **WorkflowGraph** — add nodes and edges by writing a `workflow.yaml` in your recipe. The live recipes are the executable contract today; `schemas/workflow.schema.json` is the target validation contract and is being aligned with the newer recipe fields such as verifier refs and human decision edges.
+2. **AgentRegistry** — register new roles or model bindings via `lib/agent_registry.sh:agent_register`. No code change.
+3. **VerifierRegistry** — drop a `<name>.sh` script under `${MINI_ORK_HOME}/verifiers/` or `recipes/<recipe>/verifiers/` and reference it in `workflow.yaml`.
+4. **ExperienceMemory** — add new namespaces via DB migrations or override `lib/context_assembler.sh` per task class.
+
+Embedding from Python is first-class too — `MiniOrk().run(RunRequest(...))` with typed specs: [docs/PYTHON_FRAMEWORK.md](docs/PYTHON_FRAMEWORK.md).
+
+---
+
+## Bounded Autonomy
+
+Self-improvement is evidence-gated, not free-running. Changes are ranked by risk:
+
+| Rung | Mutation | Gate required |
+|---|---|---|
+| 1 | Tune prompt wording | None — always safe |
+| 2 | Tune retrieval / context assembly | None — always safe |
+| 3 | Tune workflow graph edges | Benchmark pass |
+| 4 | Tune agent role definitions | Benchmark pass |
+| 5 | Tune verifier selection | Benchmark pass |
+| 6 | Propose code changes to mini-ork itself | Benchmark pass + human review |
+| 7 | Promote runtime changes | Benchmark pass + human gate + `version_clear_quarantine` if previously quarantined |
+
+Auto-promotion is **class-restricted**: task classes with an external oracle (test suites, schema validators) can auto-promote on green; LLM-judged classes (synthesis, audits) are manual-promote-only — the framework refuses to fabricate an oracle it doesn't have. See [docs/SAFETY.md](docs/SAFETY.md) for immutable constraints and the PromotionGate contract.
+
+---
 
 ## Roadmap
 
-The near-term work is operational trust: truthful dispatch telemetry, error and
-finish-reason taxonomy, heartbeat/failure handling, capability-aware routing, cost
-accuracy, and operator intervention policies. See the full [roadmap](ROADMAP.md).
+**Current: v0.3.0-rc2** (release candidate, 2026-06-10) — CI-gated observability, security, and reliability hardening on top of the v0.3 oracle-hardening primitives: `coalition_gate.sh`, `cw_por.sh`, `mo_promote_synthesis_gate`, `adaptive_stability.sh`, `circuit_breaker.sh`, plus the central `gate_bootstrap.sh` wiring used by execute. Self-evolution is now explicitly class-restricted (`docs/positioning/why-mini-ork.md` §"Self-evolution is class-restricted").
+
+The full release log lives in [`ROADMAP.md`](ROADMAP.md) — every section dated and per-commit-attributed. Current shipped totals (regenerable via `bash scripts/readme-claim-check.sh` and filesystem counts):

+## Recursive self-improvement evidence (2026-06-09 session)
+
+The `recursive-self-improve` recipe ran against mini-ork itself for ~5 wall-clock hours, producing **10 commits to `main` autonomously** — each grounded in cited arXiv evidence per the recipe's "new infra requires arXiv evidence" hard rule. Audit trail lives in `self_improve_runs`, `learning_record`, and `self_improve_arxiv_refs` tables; per-iter synthesis files are preserved under `.mini-ork/runs/`.
+

+| 33 | `77f965f` | Deterministic profile-seed from structured kickoff markdown | 2601.04620; 2604.08633 |
+
+Cumulative DB state at session end: **23 arXiv references cited across the session; 19 marked `used_in_patch=1`** (i.e. landed in main via cherry-pick). The recipe's safety rule was respected in both directions — every patch proposing new infrastructure cited a paper; every in-place adapter explicitly stated no citation required.
+
+The first three patches (`c5b819c`, `e95e641`, `6a66e28`) were emergent — the loop found these bugs by reading its own prior run logs. Iter 18 (utility-delta) and iter 32 (duration_ms) targeted operator-seeded `learning_record` rows. Iter 33 is the most interesting: it healed a symptom of its own iter-19 patch (the profile-gate caused a spiral under a meta-kickoff; iter 33 fixed the root cause by deterministically populating the profile from structured kickoff sections, making the gate's "needs_answers" verdict honest rather than blocking).
+
+Supporting fixes that landed alongside the loop's autonomous output: `lib/throttle-guard.sh` (provider-error classification + per-lane backoff + systemic-halt at 3 simultaneous providers), `bin/mini-ork-self-improve` pre-iter cost-cap pre-check (halt before worktree creation when `SUM(task_runs.cost_usd)` over 24h exceeds `MO_DAILY_BUDGET_USD`), Anthropic-native wrapper policy clarification (`cl_opus.sh` / `cl_sonnet.sh` only unset env vars, deferring to Claude Code ambient auth — gateway wrappers `cl_glm.sh` / `cl_kimi.sh` / `cl_minimax.sh` / `cl_deepseek.sh` keep setting `ANTHROPIC_AUTH_TOKEN` because they route to non-Anthropic endpoints).
+
+Operational env vars added during this session: `MO_DAILY_BUDGET_USD` (cost circuit cap), `MINI_ORK_PROFILE_GATE` (planner profile gate; off by default for the recursive loop), `MINI_ORK_PLAN_CONFIDENCE_FLOOR` (gate threshold), `MINI_ORK_SELF_IMPROVE_BASE_REF` (worktree base ref, defaults to `main`), `MINI_ORK_BENCH_UTILITY_THRESHOLD` + `MINI_ORK_BENCH_MIN_N` (utility-delta gate parameters), `MINI_ORK_THROTTLE_EMPTY_ITER_THRESHOLD` (spiral halt), `MINI_ORK_PRE_ITER_COST_CHECK` (pre-iter cost-cap pre-check override). See `docs/RECURSIVE-SELF-IMPROVE.md` for the operator guide.

-### Proposed research track — verifier-led escalation and learning
-
-This is a research proposal informed by recent work on recovery-oriented RL
-initialization and interaction-budget policies. It is **not** a claim that
-MiniOrk currently trains or deploys this policy. It builds on the telemetry,
-rubric, checkpoint, and intervention-policy work above.
-
-1. **Decision-checkpoint evidence.** Record the available actions, verifier
-   state, uncertainty, cost, latency, and user-interruption outcome at every
-   escalation decision. A learning system cannot improve a decision it cannot
-   audit.
-2. **Recovery-behavior library.** Mine verifier-grounded failure traces for
-   reusable repair behaviors—reproduce, inspect, narrow scope, rerun a tool,
-   revise a plan, or escalate. Candidates remain human-reviewed or
-   externally verified; a frequent failure is not automatically a good fix.
-3. **Hierarchical escalation policy.** Route a blocked run among: continue
-   locally, use a cheap tool or model, re-plan, choose a stronger capable
-   lane, or interrupt the user. This extends the future `never | required |
-   always` intervention policy rather than replacing safety gates.
-4. **Reward verified information gain.** Evaluate a step by whether it
-   reduces verifier-relevant uncertainty or unlocks a valid next action,
-   then trade that progress against cost, latency, and interruption burden.
-   Do not optimize merely for fewer questions or more activity.
-5. **Offline evaluation before live learning.** Compare the learned router
-   with fixed escalation ladders on held-out, task-class-specific traces.
-   Report verifier pass rate, cost per verified success, time to resolution,
-   false-escalation rate, and unnecessary-interruption rate. Keep
-   deterministic-oracle and human-judged classes separate.
-
-Graduation criterion: a proposed policy needs reproducible improvement over a
-fixed baseline without lowering verifier pass rate or weakening the existing
-promotion and safety gates.

-## verifiers (Prime Intellect) — MIT
-
-- **Upstream:** https://github.com/PrimeIntellect-ai/verifiers
-- **License:** MIT
-- **Version:** `>=0.2.0,<0.3` — the `verifiers.v1` namespace, which upstream ships as a
-  *preview*. We pin deliberately and bump on purpose.
-- **Used by:** `mini_ork/runtime/` (Crucible — our verified-execution seam). This is the
-  **only** import site; nothing else in mini-ork may import `verifiers`, so an upstream API
-  change touches exactly one file.
-- **What we use it for:** the `verifiers.v1.runtimes` **Runtime protocol** — one interface
-  (`start`/`run`/`read`/`stop`/`teardown`) over four interchangeable backends: `docker` and
-  `subprocess` locally, `prime` and `modal` in the cloud. That is genuinely better than
-  anything we would hand-roll, and it makes cloud execution a config field rather than a
-  rewrite. (Their v1 message-DAG trace and interception server are on our roadmap for the
-  same reason; not wired yet.)
-- **Why we depend rather than fork:** upstream ships daily and v1 is explicitly a preview.
-  A fork would rot within a month. We depend, pin, and wrap behind our own seam — and when
-  `verifiers` is absent, Crucible drives the `docker` CLI directly and behaves identically,
-  so mini-ork stays zero-dependency by default.
-- **Where we diverge — and where we do not.** It would be wrong to say `verifiers` "scores
-  with an LLM judge." In v1 a task's `@vf.reward` is arbitrary Python, and their SWE
-  tasksets score on test execution exactly as we do. The real divergence is a **layer they
-  do not have**: nothing in their stack — or in Harbor, or in any harness in their registry
-  — asks whether a **passing** patch is **actually correct**. A reward function returning
-  `1.0` because the test went green *is* the extensional-verifier-hacking failure mode
-  (a patch can special-case the test; ~73.6% shortcut rate under compute pressure). mini-ork
-  adds two layers on top of theirs:
-    - **Crucible** (`mini_ork/runtime/`) — execution-anchored outcome. Its `failed` vs
-      `error` split is ours: an *error* is a broken environment, not a failed patch, and
-      blaming the patch for it is a false-reject (PR #170). A judge may **veto**, never
-      **approve** (PR #168, `reward_from_status`).
-    - **Assay** — the solve-time oracle (PoC+ extraction, metamorphic amplification, delta
-      gating, explicit abstention). This has no counterpart upstream and is the component we
-      claim as differentiating.

+I want the token bill next to any chart calling Fable more intelligent.
+
+The uncomfortable part of current reasoning-model marketing is that a public score can hide two very different improvements. One is a better model. The other is a model spending more inference-time compute: more hidden reasoning, more retries, longer traces, more latency, more dollars. Both can produce better answers. Only one deserves to be sold as raw intelligence without a footnote.
+
+That distinction matters because test-time compute is no longer a side trick. It is a whole research area.

+This is the scientific version of my complaint: Fable may be more capable at Anthropic's chosen operating point, but the public claim is incomplete unless it reports the inference budget that bought the capability.
+
+## The friendly reading
+
+Giving a model more compute at inference time can improve reasoning, and that is the strongest version of Anthropic's case.
+
+[The Art of Scaling Test-Time Compute for Large Language Models](https://arxiv.org/abs/2512.02008), a study across eight open-source LLMs and more than thirty billion generated tokens, lands on a narrower result than "more tokens good": the best strategy depends on model type, problem difficulty, and compute budget. No single test-time strategy universally dominates.
+
+That is already enough to change how a model card should read. If Fable gets its jump by using a more aggressive reasoning policy, that is a valid engineering achievement. But it is a compute-allocation achievement. It should be measured as one.
+
+The same point shows up in [Can 1B LLM Surpass 405B LLM?](https://arxiv.org/abs/2502.06703), which argues that compute-optimal test-time scaling can let much smaller models beat much larger ones on some math benchmarks. The lesson is awkward for vendor marketing: benchmark wins can come from the inference procedure, not only from a more intelligent base model.
+
+In other words, a model endpoint is a bundle:
+
+| Layer | What the user sees | What the benchmark may hide |
+|---|---|---|
+| Base model | The answer | Parameter count, training mix, RL policy |
+| Inference policy | The answer quality | Number of samples, verifier passes, hidden reasoning budget |
+| Serving stack | The latency | batching, routing, speculative decoding, hardware |
+| Product defaults | The bill | token caps, retry policy, tool-call policy |
+
+Calling the whole bundle "more intelligent" is convenient but not precise.
+
+## The token tax
+
+The term I would use for Fable-style claims is the token tax: the extra reasoning budget paid to move an answer from acceptable to impressive.
+
+That tax is sometimes worth paying. [Economic Evaluation of LLMs](https://arxiv.org/abs/2507.03834) makes the case cleanly: if a wrong answer is expensive, the most powerful model can be the economically correct choice even when its per-call cost is higher. For a legal review, a production migration, or an autonomous agent editing a repository, paying more for fewer mistakes may be rational.
+
+But that does not make the tax disappear. It means the tax has to be priced against the cost of an error.
+
+The failure mode is using the expensive setting everywhere and calling the resulting average "intelligence." [Plan and Budget](https://arxiv.org/abs/2505.16122) names the pattern directly: reasoning models often overthink, generating verbose or tangential traces even for simple queries. The paper's proposed fix is not "never think." It is adaptive budgeting: decompose the problem, estimate complexity, and allocate tokens where uncertainty is high.
+
+That is the standard Fable should be held to. Not "can it produce the best answer if allowed to spend?" But "does it know when not to spend?"
+
+## More thinking can hurt
+
+The easiest way to overstate a reasoning model is to draw only the high-budget point on the curve.
+
+[When More Thinking Hurts](https://arxiv.org/abs/2604.10739), the paper I would put in the center of the critique, reports diminishing returns at higher reasoning budgets, and identifies cases where extended reasoning is associated with abandoning previously correct answers.
+
+That result should make everyone cautious about the phrase "more intelligent." Longer reasoning is not a monotone good. On some tasks it helps. On some tasks it wastes compute. On some tasks it gives the model enough rope to talk itself out of the right answer.
+
+[The Price of a Second Thought](https://arxiv.org/abs/2505.22017) frames the same issue as reasoning efficiency. Thinking models can waste computation on easy problems while adding value on harder ones. That sounds obvious until you look at how leaderboards are usually consumed: a single score, detached from how much compute was spent to get it.
+
+If Fable wins hard reasoning tasks by spending more on hard reasoning tasks, good. That is the right use of test-time compute. If it spends the same swollen budget on trivial tasks, the product is not smarter in the way users care about. It is expensive by default. That default only becomes defensible if a benchmark separates Fable's accuracy gain from the tokens, latency, and dollars spent to buy it.
+
+## The benchmark I want
+
+[OckBench](https://arxiv.org/abs/2511.05722) says the quiet part clearly: current benchmarks over-emphasize accuracy and output quality while neglecting token efficiency. It reports that models with similar accuracy can differ heavily in token length. That is not a cosmetic metric. It changes latency, serving cost, energy, and whether an agentic workflow fits inside a real budget.
+
+So I do not want a single Fable win-rate chart. I want a frontier.
+
+| Question | Why it matters |
+|---|---|
+| Accuracy at fixed output-token ceilings | Separates better reasoning from longer reasoning |
+| Accuracy at fixed dollar budget | Tells operators what they can actually buy |
+| Accuracy at fixed latency budget | Matters for interactive products |
+| Easy/hard task split | Reveals overthinking on easy tasks |
+| Token distribution, not just average | Shows tail behavior and runaway traces |
+| Prior Claude vs Fable at same budget | Tests whether the endpoint moved the frontier |
+| Fable vs cheaper non-Anthropic endpoints at same budget | Tests whether the premium is economically justified |
+
+The key phrase is "moved the frontier." If Fable gets higher accuracy at the same cost and latency, Anthropic has a strong claim. If it gets higher accuracy by moving to a much more expensive point on the same curve, the claim is weaker. It may still be a useful product. It is not the same scientific statement.
+
+## The line I would draw
+
+Here is the charitable, technical version:
+
+> Fable may be a better endpoint, but Anthropic has not shown whether it is a more efficient reasoner. Without token-normalized and cost-normalized results, the claim "more intelligent" mixes model capability with test-time compute policy.
+
+That is not anti-Anthropic. It is anti-unpriced-intelligence.
+
+The field already has the vocabulary: test-time scaling, overthinking, reasoning efficiency, compute-accuracy Pareto frontiers, economic evaluation. Vendors should use it. If a model is better because it thinks longer, say that. If it is better because it spends tokens more selectively, show the easy/hard split. If it is better at the same budget, publish the frontier and take the win.
+
+Until then, my working assumption is simple: every "smarter" reasoning model comes with a hidden invoice. I want the invoice printed next to the benchmark.

+
+I want the token bill next to any chart calling Fable more intelligent.
+
+The uncomfortable part of current reasoning-model marketing is that a public score can hide two very different improvements. One is a better model. The other is a model spending more inference-time compute: more hidden reasoning, more retries, longer traces, more latency, more dollars. Both can produce better answers. Only one deserves to be sold as raw intelligence without a footnote.
+
+That distinction matters because test-time compute is no longer a side trick. It is a whole research area.

+# mini-ork conductor — meta-orchestrator (mini-ork-of-mini-orks).
+#
+# Phase 2 of the design grounded in Shepherd (arXiv:2605.10913),
+# TaskWeave (2606.01199), TacoMAS (2605.09539), Mass (2502.02533),
+# InfraMind (2606.11440) and TCP-MCP (2605.27850).
+#
+# Per tick:
+#   1. Read state of: epic queue, prompt_win_rates, agent_performance_memory,
+#      topology_win_rates, role_evolver_log proposals, 24h cost vs cap.
+#   2. Pick the next epic from epic_graph_ready_now.
+#   3. Decide:
+#        - Recipe / topology  (highest win_rate per task_class, ties broken
+#          by lower avg_cost; falls back to the epic's kickoff hint)
+#        - Lane hints         (highest relative_advantage per (lane, task_class))
+#        - Prompt seeds       (top-quartile prompt_version_hash for the role)
+#      Under high budget pressure (>70% spend), prefer cheaper topologies
+#      with sample_size >= 3 over higher-win-rate but expensive ones
+#      (InfraMind-style budget bias).
+#   4. Write the decision to conductor_decisions.
+#   5. Stage the lane hints + prompt seeds into env vars and call
+#      bin/mini-ork-scheduler --once.
+#
+# Modes:
+#   --once               One decision + dispatch then exit

+#   --idle-secs N        Poll interval when queue empty (default 60)

+You are a meticulous task planner. Given the kickoff document below, produce a
+structured plan in JSON.
+
+The JSON MUST have these top-level keys:
+  objective          (string)
+  assumptions        (string[])
+  decomposition      ({id, description, node_type, depends_on[]}[])
+    node_type must be one of: planner | researcher | implementer | reviewer |
+                               verifier | reflector | publisher | rollback
+  dependencies       ({from, to}[])
+  risk_notes         (string[])
+  artifact_contract  ({outputs: string[], success_verifiers: string[]})
+  verifier_contract  ({checks: {id, description, command?}[]})
+
+IMPORTANT: verifier_contract.checks must contain at least one item.
+A plan without a verifier_contract is INVALID.
+
+When checking provider policy for researcher lanes, use the canonical
+llm_calls ledger shape:
+  sqlite3 ${MINI_ORK_DB} "SELECT COUNT(*) FROM llm_calls WHERE actor='researcher' AND provider='anthropic' AND ts > datetime('now','-6 hours');" | grep -q '^0$'
+Do not query legacy/non-existent llm_dispatch(role, created_at).
+
+Respond with ONLY valid JSON. No markdown fences, no prose.

+# mini-ork watchdog — periodic early-failure prediction for active runs.
+#
+# Track B item 5 (arXiv:2605.08715, Online Auditing for Early Failure
+# Prediction in Multi-Agent Systems). Polls every active task_run, looks
+# at the per-node traces emitted so far, computes a similarity match
+# against known-failing pattern_records clusters, and when the match score
+# exceeds MO_WATCHDOG_ABORT_THRESHOLD (default 0.65) writes
+# .stop-requested into the run dir. bin/mini-ork-execute checks that file
+# at the next node boundary and bails before more cost is sunk.
+#
+# Flags:
+#   --once                Single pass over active runs, then exit
+#   --poll-secs N         Idle seconds between passes (default 30)
+#   --dry-run             Print decisions, do not write .stop-requested
+#   --threshold T         Match score >= T triggers abort (default 0.65)
+#   --warn-only           Log to watchdog_aborts but never write the file
+#   --help
+#
+# The watchdog logs every decision (abort, warn, no-match) to
+# watchdog_aborts so the false-positive rate can be measured.

--- mini-ork migration 0050 — make the conductor falsifiable
---
--- THE BUG: the conductor predicts a score for every decision and never records what it
--- actually got. Measured on a live db: 10 decisions, 10 with predicted_score, ZERO with
--- realized_score. It is uncalibrated BY CONSTRUCTION — it cannot learn from its own choices,
--- and no UI can ever answer "was the recommendation right?", because nothing wrote the answer.
---
--- WHY the existing write-back never fires. mini_ork_execute.py reconciles like this:
---
---     SELECT cd.id, e.status FROM conductor_decisions cd
---       JOIN epics e ON e.id = cd.epic_id
---      WHERE COALESCE(cd.outcome,'pending')='pending' AND e.status IN ('done','escalated')
---
--- It waits on an EPIC reaching a terminal state. But a `bin/mini-ork run` completes a
--- TASK_RUN and does not necessarily advance any epic — on the live db all 10 decisions point
--- at epic `libwit-se-1`, whose status is still `not started`. For run-driven work the
--- reconciliation can never fire. The outcome is unreachable, not merely unwritten.
---
--- FIX 1 — link a decision to the RUN it produced (task_run_id), so realized_score can be
--- reconciled from the thing that actually finishes. The epic path stays as a fallback for
--- epic-driven work; this adds the run path that was missing.
---
--- FIX 2 — record what was PROPOSED alongside what was CHOSEN, and who chose it.
---
--- The second is the more valuable one. When a human overrides the conductor and the run is
--- then verified, that is a LABELLED EXAMPLE: "the system proposed X, a human chose Y, and Y
--- turned out better/worse". That is the highest-value training signal in the product, and
--- today it has nowhere to go — conductor_decisions records only the final choice, so a human
--- correction is indistinguishable from the machine agreeing with itself.

-### Node type dispatch semantics
-
-The `workflow.yaml` fields above describe the *shape* of a node. They don't
-describe what `mini_ork/cli/execute.py` actually *does* with each `type` at
-dispatch time — and the difference matters: two node types that look
-interchangeable have very different guarantees about whether your LLM
-call's output actually becomes a usable artifact.
-
-| Type | Write-target injected into prompt? | Response captured if the model doesn't write a file itself? | Gated on a `verdict`? |
-|---|---|---|---|
-| `researcher` | Yes — `"Write your output to: $RUN_DIR/context-<node_id>.json"` (a real resolved path, not a variable the model has to expand) | Yes — raw response text is saved to that path as a fallback | No |
-| `reviewer` | Yes — same as `researcher`, saved to `$RUN_DIR/review-<node_id>.json` | Yes — same fallback | **Yes**, see below |
-| `implementer` | No | **No.** `IMPL_LOG` only stores raw stdout for forensics; it is never treated as a data artifact | No |
-| `verifier` | N/A (runs `verifier_ref` script, no LLM call) | N/A | N/A (exit code is the verdict) |
-| `publisher` / `rollback` | N/A (`prompt_ref: null`, deterministic) | N/A | N/A |
-
-**Use `researcher` for any stage whose job is "generate content and hand it
-to the next node."** This is the default choice — it's what every shipped
-lens/synthesis-style recipe (`chapter-review`, `dsp-planning-burst`) uses.
-The model doesn't need a file-write tool at all: tell it in the prompt to
-emit exactly one JSON value as its final response, and mini-ork saves it.
-
-**Use `implementer` only for actual code-editing tasks against a git
-checkout.** It's the only node type where `MO_TARGET_CWD` gets pinned to a
-worktree, matching `code-fix` / `recursive-validate-impl`'s pattern of
-having the model edit real files in a real repo. If you route a
-"generate JSON, write it to the run dir" task through `implementer`, the
-LLM call will report `[ok] implementer output` — success! — while
-producing zero usable artifact, because nothing captures its response.
-This failure mode is silent: the dispatch itself doesn't error.
-
-**The `reviewer` verdict gate.** After capturing the response,
-`lib/extract_verdict.py` looks for a `verdict` key and requires its value
-to be one of `pass`/`approve`/`approved` to succeed. `revise`/
-`needs_revision`/`request_changes`/`fail`/`failed`/`escalate` — and
-critically, *anything else, including a missing `verdict` key entirely* —
-fails the node (`return 1`) and is counted toward `FAIL_COUNT`. This gate
-exists for recipes whose edges/loop genuinely branch on the verdict
-(escalate-to-reflector patterns). If your reviewer node is informational
-only — its prompt's real output contract has no `verdict` field, e.g.
-`{"passed": bool, "notes": "..."}`  — this gate will unconditionally fail
-that node regardless of how valid the content is. Use `type: researcher`
-instead; it captures identical content without the gate.

-# mini-ork Python SDK
-
-mini-ork is usable two ways, and they compose:
-
-1. **Primitives** — importable, in-process building blocks. No YAML, no
-   subprocess, no provider credentials to *construct* them. This is what most
-   applications embedding mini-ork actually want.
-2. **Orchestrator** — the full `classify → plan → execute → verify` lifecycle,
-   driven from Python via the `MiniOrk` client (it shells out to the `mini-ork`
-   CLI behind a stable `--json` result contract).
-
-## Install
-
-```bash
-pip install -e '.[full]'   # from a checkout; installs the CLI + runtime too
-python3 -c "import mini_ork; print(sorted(dir(mini_ork)))"
-```
-
-## Primitives
-
-```python
-from mini_ork import (
-    Crucible, RuntimeSpec, ExecOutcome, available_backends,  # verification
-    dispatch_model, DispatchRequest, DispatchResult,          # model dispatch
-    memory,                                                   # verified memory
-    router, preferred_lane, recompute_advantages,             # bandit routing
-)
-```
-
-Heavy modules load lazily (PEP 562), so `import mini_ork` stays cheap — you only
-pay for the dispatch/runtime/memory machinery when you reference it.
-
-### Execution-anchored verification — `Crucible`
-
-The verdict on a change is what the code *did when it ran*, not a model's
-opinion. `run_test` returns an `ExecOutcome` whose `status` is the primary
-signal (`passed` / `failed` are the only ones that say anything about the
-patch; `test_defect` / `error` / `apply_fail` / `no_run` are facts about the
-harness).
-
-```python
-cru = Crucible(RuntimeSpec(image="python:3.11-slim", backend="auto"))
-outcome = cru.run_test(test_src="def test_x():\n    assert add(2, 2) == 4\n", patch=my_patch)
-if outcome.informative:          # passed or failed — real evidence
-    ship = outcome.passed
-elif outcome.test_is_broken:     # repair the probe, do not blame the patch
-    ...
-```
-
-`available_backends()` reports where execution can happen (`docker`,
-`subprocess`, `prime`, `modal`, `docker-cli`).
-
-### Heterogeneous dispatch — `dispatch_model`
-
-One call, any provider lane. An unroutable lane or a missing key comes back as a
-**structured `ok=False`** result — never a raise, stall, or repo corruption.
-
-```python
-res = dispatch_model(DispatchRequest(model="codex", prompt="…"))
-if res.ok:
-    text, cost = res.text, res.cost_usd
-else:
-    handle(res.error, res.rc)
-```
-
-### Verified-outcome memory — `memory`
-
-Scoped semantic memory backed by SQLite; the stdlib `HashEmbedder` means no new
-dependency and no network for a basic roundtrip.
-
-```python
-from mini_ork import memory
-memory.add("ingest lane retry budget is 3", scope="proj", infer=False)
-hits = memory.search("how many ingest retries?", scope="proj", top_k=3)
-```
-
-### Cost-free bandit routing — `router`
-
-`preferred_lane(task_class, node_type=…)` returns the lane that has been winning
-for that role, learned from verified outcomes at zero extra model calls. It
-reads a warmed state db (`mini-ork init` + a few runs); with no priors it
-returns the default.
-
-## Orchestrator
-
-```python
-from mini_ork import MiniOrk, RunRequest
-mo = MiniOrk()
-result = mo.run(RunRequest(kickoff="kickoff.md", recipe="code-fix", mode="live"))
-print(result.run_id, result.verdict, result.ok)
-```
-
-`RunResult` is populated from the CLI's machine-readable `--json` contract
-(`mini_ork_result={…}`), so `run_id` / `task_class` / `plan_path` / `verdict` /
-`returncode` are parsed from one structured line rather than scraped from human
-output. Define recipes in code with `RecipeBuilder` (see `mini_ork.extensions`)
-or point at YAML — both are supported.
-
-## Runnable example
-
-```bash
-python3 examples/sdk/hello_world.py
-```
-
-Exercises backends, a real memory roundtrip, routing, and the fail-fast dispatch
-contract — all in-process, no configuration.

-### Contested-finding proof quotes
-
-- X2, Codex partial: `lens-codex.md:5` says `PARTIAL on X2 (real signal, but the "13" headline understates it).`
-- X2, Kimi partial: `lens-kimi.md:16` says reviewer confidence mode is `0.88` and only about 16 rows are `>=0.90`, so the `0.92-0.95` dominant-band framing is loose.
-- X2, Opus qualification: `lens-opus.md:12` agrees the diagnosis quality is real, but warns that confidence is model self-consistency, not apply-side value.
-
-## 2. Verdict changes
-
-No finding is overturned outright. The panel qualifies five findings and corrects two mechanisms/numeric claims.
-
-### G1 qualified: intentional off-state, not standalone defect
-
-The stated fact is true: GEPA is off unless `MO_OPTIMIZER=gepa`. Opus explicitly classifies this as deliberate pre-launch opt-in: `bin/mini-ork-reflect:226-232` says the default path leaves the block skipped (`lens-opus.md:4`). MiniMax adds that even `MO_OPTIMIZER=gepa` is insufficient without `_GEPA_TASK_CLASS` or `MO_OPTIMIZER_ALLOW_DEFAULT=1` (`lens-minimax.md:99-100`).
-
-Change: do not fix G1 by simply removing the gate. Fix the production wiring and only then enable the optimizer path.
-
-### G3 mechanism corrected: unknown lane, not a working stub provider
-
-The finding remains fatal, but the mechanism changes. Kimi shows `"stub"` is not in `KNOWN_MODELS`, so dispatch fails before a rewrite is proposed (`lens-kimi.md:33-38`). Opus confirms the same call chain through `providers.py:29-31`, `providers.py:193-197`, and `_NoProposal` (`lens-opus.md:6`).
-
-Change: fix G3 and G2 together. Passing a real model only exposes G2's acceptance-gate failure.
-
-### G4 and Gr3 qualified: deliberate suggest/proposed stages, missing upper apply path
-
-Opus says `mini-ork-reflect:229` explicitly describes GEPA as suggest-only and no consumer promotes `prompt_change` rows (`lens-opus.md:7`). For Gr3, Opus notes `reflection_persist_suggestions` intentionally writes `status='proposed'`, but no consumer moves rows to approved/rejected/apply (`lens-opus.md:10`).
-
-Change: the defect is not that the lower stages write `suggested`/`proposed`; the defect is the missing Apply → Online-eval → Gate → Promote stage.
-
-### Gr2 mechanism and count corrected
-
-The outcome stands: semantic duplicates survive. But Kimi shows the original mechanism is imprecise: pass 1 uses `signal`, while the extractor containment pass uses combined `signal + suggested_change` (`lens-kimi.md:20-28`). Opus adds the deeper failure: the cross-target pass skips same-target rows, so the 172 `agent.reviewer.prompt` rows are not compared by that pass at all (`lens-opus.md:20-21`). Kimi also rejects the original `13` count and finds 57-58 evidence/verdict-like reviewer rows (`lens-kimi.md:29-32`).
-
-Change: rewrite Gr2 as "dedup keys on lexical form and skips the concentrated same-target duplicate case," not "both passes key only on signal."
-
-### X2 numeric/value framing qualified
-
-MiniMax and Opus agree the diagnosis asset is real (`lens-minimax.md:48`; `lens-opus.md:12`). Codex and Kimi partially agree but reject the exact headline numbers (`lens-codex.md:5`; `lens-kimi.md:16`). Opus further notes confidence is not calibrated by apply-side outcomes (`lens-opus.md:48-49`).
-
-Change: keep X2 as a real wasted-asset finding, but do not sell it as proven by a dominant `0.92-0.95` band. The stronger metric is 39 proposed patterns and 0 applied changes.
-
-### X1 promoted to top priority
-
-Opus explicitly says X1 is the load-bearing structural defect and that G2/G4/Gr1/Gr2/Gr3 are symptoms (`lens-opus.md:22-27`). MiniMax similarly says the central claim is verified end-to-end and the two highest-leverage fixes are apply-path/dedup and reflect-trace exclusion (`lens-minimax.md:106-108`).
-
-Change: rank X1 first. Bookkeeping fixes help cost, but X1 is what unlocks value.
-
-## 3. Implementation-ready set
-
-### HIGHEST-confidence, safe to implement with qualifications
-
-1. **X1 — build Apply → Online-eval → Gate → Promote.**
-   - Proof: all apply-side tables are empty while diagnose-side artifacts exist (`lens-kimi.md:15`; `lens-opus.md:11`; `lens-minimax.md:47`).
-   - Implementation constraint: online-eval must be included; applying without reward comparison recreates theater (`lens-opus.md:63-64`).
-
-2. **G2 + G3 — fix as one paired GEPA execution path.**
-   - Proof: G3 currently short-circuits before G2 (`lens-opus.md:18`), and G2 still rejects even if a real model is wired (`lens-kimi.md:40-64`).
-   - Implementation constraint: pass a real model lane and replace hash-only offline scoring with online or held-out scoring of mutated prompt text.
-
-3. **G4 + Gr3 — add consumers for `prompt_change` and `emergent_patterns.status='proposed'`.**
-   - Proof: `workflow_candidates`, `promotion_records`, `version_registry`, and `textual_gradients` are all empty (`lens-opus.md:7`; `lens-opus.md:10`; `lens-minimax.md:43`, `lens-minimax.md:46`).
-   - Implementation constraint: do not merely flip statuses; route proposed changes through the X1 gate.
-
-4. **Gr1 — make reflection extraction idempotent and bounded.**
-   - Proof: 9,777 gradient rows from 1,603 traces, worst trace re-mined 29 times (`lens-kimi.md:12`; `lens-opus.md:8`; `lens-minimax.md:44`).
-   - Implementation constraint: use per-trace watermark or slice-claim semantics; exclude `__reflect__` traces because they account for 926 gradient rows (`lens-minimax.md:60-67`).
-
-5. **G1 — keep the gate, but make enabling meaningful.**
-   - Proof: off-state is deliberate (`lens-opus.md:4`), and secondary task-class/default gates also apply (`lens-minimax.md:99-100`).
-   - Implementation constraint: enabling GEPA should be the final switch after G2/G3/X1 wiring, not the first patch.
-
-### HIGH but not implementation-ready as originally worded
-
-- **Gr2** — implement dedup, but use corrected mechanism: same-target duplicate handling plus semantic/normalized intent over `suggested_change`, not only signal text (`lens-kimi.md:20-28`; `lens-opus.md:20-21`; `lens-minimax.md:72-73`).
-
-### CONTESTED / needs another look
-
-- **X2** — keep as strategic motivation, not a standalone numeric proof. The current signal is real but self-reported confidence is not value-calibrated (`lens-kimi.md:16`; `lens-opus.md:48-49`).
-
-## 4. Missed findings
-
-### Codex additions
-
-- Rank-based overwrite branch in `miniork_adapter.py:153-156` is cache-key-insensitive (`lens-codex.md:8`).
-- `model="stub"` defaults exist at both `gepa.py:148` and `miniork_adapter.py:311`, so fixing only one level leaves mutations inert (`lens-codex.md:9`).
-- Gr1 is also a cost bomb because `llm_dispatch` runs per trace per window (`lens-codex.md:10`).
-- Gr2 dedup is per `(task_class, target)`, so reviewer-evidence insights repeated across task classes do not collapse (`lens-codex.md:11`).
-- `validity="insufficient_evidence"` is silently dropped in `bin/mini-ork-reflect:258-260`, making cold DB runs indistinguishable from no run (`lens-codex.md:12`).
-- `reflection_pipeline.sh:104-110` `LIMIT 10000` oldest-first can leave latest-window rows lagging in dedup (`lens-codex.md:13`).
-- Retro-added `task_class` can group pre-migration rows under empty string and defeat future cross-epic dedup (`lens-codex.md:14`).
-
-### Kimi additions
-
-- `validity:"valid"` conflates "ran" with "improved"; zero accepted mutations can still persist as a valid prompt change (`lens-kimi.md:70-78`).
-- The evaluator is blind to prompt text; naive `MO_OPTIMIZER=gepa` fixes still accept nothing if evaluation remains hash-only (`lens-kimi.md:80-88`).
-- Dedup can be outrun once the table exceeds bounded batch size because overlapping extraction can grow faster than capped dedup removes (`lens-kimi.md:90-98`).
-
-### MiniMax additions
-
-- Recursive reflect-mining: `__reflect__` traces re-enter extraction and account for 926 gradient rows (`lens-minimax.md:60-67`).
-- No rate-limit/change-gate on auto-reflect; every run fires multiple side effects and can spend heavily with no gain (`lens-minimax.md:69-70`).
-- Cross-target dedup is structurally blind to within-target duplicates because same-target rows are skipped (`lens-minimax.md:72-73`).
-- Reflection extraction batch truncation is silent; visible vs processed trace count is not reported (`lens-minimax.md:75-76`).
-- No retention/GC across gradient, pattern, and cross-class tables (`lens-minimax.md:78-79`).
-- `evaluate()` rank-based override is order-coupled and brittle (`lens-minimax.md:81-82`).
-- `_default_score` is a global mean, biasing GEPA toward no change (`lens-minimax.md:84-85`).
-- Cross-class gradient promotion writes `__cross_class__` rows without a bound/upsert (`lens-minimax.md:87-88`).
-- GRPO-side overlays populate tables that are not read by dispatch yet (`lens-minimax.md:90-91`).
-- Pattern upsert can reset status/resolution state (`lens-minimax.md:93-94`).
-- `--task-class` filter is not plumbed through `reflection_run` (`lens-minimax.md:96-97`).
-- GEPA block has a secondary `_GEPA_TASK_CLASS` / `MO_OPTIMIZER_ALLOW_DEFAULT` gate (`lens-minimax.md:99-100`).
-
-### Opus additions
-
-- GEPA suggestions written to `pattern_records` can pollute downstream consumers if no apply path reads them (`lens-opus.md:31-32`).
-- `--since 24h` remains wrong-by-default even with a watermark; slice-claim semantics are cleaner (`lens-opus.md:34-35`).
-- `reflection_detect_stale` computes stale gradients and discards the output (`lens-opus.md:37-38`).
-- Silent-failure surfaces compound across gradient extraction, `stub` dispatch failure, and `_NoProposal` handling (`lens-opus.md:40-46`).
-- Confidence has no feedback loop from apply-side outcomes (`lens-opus.md:48-49`).
-- `reflect_on_component` inherits cwd/framework-tree guards, so self-optimization still needs a safe opt-in path (`lens-opus.md:51-52`).
-- Dedup on `suggested_change` needs a normalization step because prescriptions are also trace-specific (`lens-opus.md:54-55`).
-- `_score_cache` warmup is currently wasted when `cand_hash == ""` (`lens-opus.md:57-58`).
-- `textual_gradients` exists but is empty, confusing source-of-truth boundaries (`lens-opus.md:60-61`).
-- X1 fix must include online-eval or it remains theater (`lens-opus.md:63-64`).
-
-## Final synthesis
-
-The panel validates the register's central thesis: mini-ork's learning loop diagnoses repeatedly but does not act. The strongest implementation path is not to flip GEPA on directly; it is to build the missing Apply → Online-eval → Gate → Promote loop, then wire GEPA with a real model lane and prompt-text-aware evaluation, then turn on gated production use.
-
-The only contested item is X2's numeric framing. The diagnosis asset is real, but its value should be measured by applied, reward-improving changes rather than self-reported confidence bands.

-# Design: robust DB migrations + safe update mechanism
-
-> Status: proposed, 2026-07-02. Goal: let a consuming repo update mini-ork to
-> the latest version **without ever overriding its `state.db`** — with integrity
-> checks, transactional safety, and code re-vendoring built in.
-
-## What exists today (and why it still forces DB wipes)
-
-mini-ork already has a migration system, so this is a *hardening* job, not a
-greenfield one:
-
-- `db/migrations/NNNN_*.sql` (46 files), applied in lex order by `db/init.sh`.
-- A `schema_migrations(filename, applied_at, checksum)` table (created in
-  `0001_core.sql`) tracks what's applied; `init.sh` skips already-applied files.
-- `bin/mini-ork-update` applies pending migrations to a project's `state.db`,
-  reports config drift, and supports `--dry-run` / `--pull`.
-
-**The real gaps that make people wipe the DB:**
-
-1. **Placeholder checksums.** `init.sh` stores `checksum='runner-applied'`, not a
-   hash. There is *no* integrity check — a shipped migration edited after release
-   goes undetected, and drift can't be diagnosed.
-2. **No code re-vendor for vendored consumers.** `mini-ork-update --pull` only
-   works when `MINI_ORK_ROOT` is a git checkout. A repo that *vendored* mini-ork
-   into `.mini-ork/` (the normal case — e.g. the researcher fleet) has no
-   supported way to pull the new **framework code**, so people hand-rsync or wipe.
-3. **No backup / no transaction.** A migration that fails midway leaves a
-   half-migrated `state.db` with no rollback → the fastest "fix" is to delete it.
-4. **Idempotency hacks.** `ensure_column(...)` + the `0018` special-case in
-   `init.sh` are band-aids for migrations that weren't cleanly re-runnable —
-   fragile, and they run *outside* the tracked migration flow.
-5. **Conflated concerns + weak CLI.** `init.sh` mixes WAL setup, column repair,
-   migrations, and views; `mini-ork-update` isn't wired as `mini-ork update` in
-   the main dispatch table.
-
-## Design principles
-
-- **Never touch data on update.** `state.db`, `config/secrets.local.sh`,
-  `config/agents.yaml`, `runs/` are sacred. Update only replaces framework code
-  and applies additive migrations.
-- **Apply each migration exactly once, transactionally, and verify integrity.**
-- **Fail safe.** Back up before migrating; roll back on any failure.
-- **Same path for fresh install, git checkout, and vendored consumer.**
-
-## Migration layer (`lib/migrate.sh` — extracted from `init.sh`)
-
-A dedicated module, callable as `mini-ork migrate [--status|--dry-run|--verify]`.
-
-**`schema_migrations` v2** (additive migration; keep `filename` PK):
-```
-filename TEXT PRIMARY KEY
-applied_at TEXT NOT NULL
-checksum TEXT NOT NULL          -- real: sha256 of the file at apply time
-mini_ork_version TEXT           -- version that applied it
-duration_ms INTEGER
-```
-
-**Apply algorithm (`mini-ork migrate`):**
-1. Ensure `schema_migrations` exists (bootstrap).
-2. For each `db/migrations/*.sql` in lex order:
-   - Compute `sha256(file)`.
-   - If already applied: **verify** the stored checksum matches. Mismatch →
-     hard error ("migration NNNN changed after being applied") unless
-     `MO_MIGRATE_ALLOW_DRIFT=1`. Never re-run.
-   - If pending: run inside `BEGIN; … COMMIT;` (SQLite has transactional DDL).
-     On success, record `(filename, now, sha256, version, duration)`. On failure,
-     `ROLLBACK`, print the offending statement, exit non-zero — the DB is
-     unchanged.
-3. Apply `db/views/*.sql` (idempotent `CREATE VIEW IF NOT EXISTS`) the same way.
-
-**`mini-ork migrate --status`** prints: applied count, pending list, any
-checksum-drifted files, current vs latest migration id. **`--dry-run`** lists
-pending without writing. **`--verify`** checks every applied checksum (CI + a
-`doctor` probe).
-
-**Migration authoring rules** (documented in `db/README.md`):
-- Additive only where possible (`ADD COLUMN`, `CREATE TABLE IF NOT EXISTS`).
-- **Never edit a shipped migration** — add a new one (the checksum guard enforces
-  this).
-- Each file is one logical change, wrapped so it's transaction-safe.
-- Retire `ensure_column`/`0018` hacks into a single idempotent
-  `00xx_repair_learning_columns.sql` that the tracker records once.
-
-## Update layer (`bin/mini-ork-update` → `mini-ork update`)
-
-Turns "update" into a safe, one-command, data-preserving operation for a
-consuming repo:
-
-```
-mini-ork update [--source <path|release>] [--dry-run] [--no-migrate]
-```
-
-**Steps (each reversible):**
-1. **Resolve source** of the new framework: `--source <dir>` (a mini-ork clone),
-   or a downloaded release tarball pinned by version, or `$MINI_ORK_SOURCE`.
-   Record `from`→`to` version (a `.mini-ork/VERSION` file).
-2. **Back up** `state.db` (+ `-wal`/`-shm`) and `config/` to
-   `.mini-ork/.backups/<from-version>-<ts>/`.
-3. **Re-vendor code** — `rsync -a --delete` the framework dirs
-   (`bin lib recipes db schemas mini_ork .githooks`) from source into
-   `.mini-ork/`, **excluding** `state.db*`, `config/secrets.local.sh`,
-   `config/agents.yaml`, `runs/`, `.backups/`. (This is exactly the manual
-   re-vendor we run today, made first-class.)
-4. **Migrate** — `mini-ork migrate` (transactional; skips on `--no-migrate`).
-5. **Verify** — `mini-ork doctor` + `mini-ork migrate --verify`.
-6. **On any failure**, restore the `state.db` backup and the previous code, and
-   report. `--dry-run` prints steps 1–4 without writing.
-
-**Config drift** (shipped `config/*.example` vs local) is *reported*, never
-auto-applied — the operator merges intentionally.
-
-## Integration + CLI
-
-- Wire `migrate` and `update` into `bin/mini-ork`'s dispatch table (today
-  `mini-ork-update` is an unlisted sibling binary).
-- `db/init.sh` keeps only bootstrap + WAL pragmas + delegate to `lib/migrate.sh`
-  (drops the inline repair hacks once the repair migration lands).
-- `mini-ork doctor` gains a "migrations: N applied, M pending, 0 drifted" line.
-
-## Phased implementation
-
-1. **P1 — real checksums + transactional apply** in a new `lib/migrate.sh`;
-   `init.sh` delegates to it. Backward-compatible: existing
-   `checksum='runner-applied'` rows are re-hashed on first `--verify`
-   (or left, with drift-allow for legacy rows).
-2. **P2 — `mini-ork migrate` CLI** (`--status/--dry-run/--verify`) + doctor line.
-3. **P3 — re-vendor step in `mini-ork update`** (backup → rsync framework →
-   migrate → verify → rollback) + `.mini-ork/VERSION`.
-4. **P4 — retire the `ensure_column`/`0018` hacks** into one repair migration;
-   simplify `init.sh`.
-
-Net: `mini-ork update` becomes a safe, idempotent, data-preserving upgrade —
-the DB is migrated forward transactionally, never overridden.

-# Bash → Python migration tracker (ADR-001)
-
-Strangler-fig: Bash stays until each Python port is parity-verified against the
-live Bash implementation. After retirement, durable pre-retirement receipts and
-standalone Python golden contracts replace tests that require deleted code.
-
-## DONE + verified (16 modules)
-
-### Trunk / Tier A — the learning brain (main repo, bash-parity tests)
-| module | python | test | notes |
-|---|---|---|---|
-| cache.sh | `mini_ork/cache.py` | `test_cache_py.py` (7) | **win #2**: dropped `iter` from match → cross-iteration hits; widened stage set. Proven vs bash (bash misses cross-iter). |
-| trace_store.sh | `mini_ork/trace_store.py` | `test_trace_store_py.py` (3) | reward_g write path; 9-payload reward_g parity. Carries **win #1** natively. |
-| lane_router.sh | `mini_ork/lane_router.py` | `test_lane_router_py.py` (10) | GRPO advantage (shrinkage/EMA/halflife/tiebreak/3-slices) + frc-a5 delayed-penalty fold + knob-direction refinements — bit-parity + preferred_lane. Retired `test_lane_router.sh` (dead fixture at HEAD: migration-subset never created `schema_migrations`, so 0 OK / 1 SKIP; its 9 fold assertions revived as live-bash parity cases) and `test_lane_router_refinements.sh` (LIVE, 5 OK/0 FAIL; its 5 knob-direction assertions revived as 4 parity cases asserting direction + `bash==port`, adding recency & two-pass-EMA coverage the top gate never exercised). |
-
-### Dispatch (Phase 1, earlier this session)
-- `mini_ork/dispatch/` is a live backend behind `MO_DISPATCH_BACKEND=python` in
-  `lib/llm-dispatch.sh` (sidecar contract preserved; codex+opus verified).
-
-### Leaf tier (isolated clone `mo-migrate`, golden-parity tests, autonomous loop)
-process_reward · similarity · utility_function · topology · pricing_strategy ·
-config_resolve · rho_aggregator — 7 modules, ~700 LOC. Resumable loop:
-`/tmp/migrate_resumable.sh` (run in a persistent terminal to finish the tier).
-
-## REMAINING (trunk)
-- **decision_service.sh** (496) — composition; needs deps ported first:
-  coalition_gate.sh, process_reward.sh (done in clone → port to main), config_resolve.sh
-  (done in clone → port), recursive_policy.
-- **Tier B:** finish `llm-dispatch.sh` (tool-summary sidecar, retire bash). The
-  context assembler is native and its Bash owner is retired.
-- **Tier C top-level forks:** verify, reflect, classify, plan, CLI, execute, and
-  the separate scheduler integration fork are closed.
-
-## Test all ported trunk modules
-    cd <repo> && python3 -m pytest tests/unit/test_cache_py.py \
-      tests/unit/test_trace_store_py.py tests/unit/test_lane_router_py.py -q
-
-## Session 2 additions (Fable, committed on feat/python-migration)
-| module | python | test | notes |
-|---|---|---|---|
-| coalition_gate.sh | mini_ork/gates/coalition_gate.py | test_coalition_gate_py.py (3) | rho taken as input; measure_rho port deferred |
-| decision_service.sh | mini_ork/steering/decision_service.py | test_decision_service_py.py (3) | full decide() surface; composes ported lane_router |
-| epic_graph.sh | mini_ork/orchestration/epic_graph.py | test_epic_graph_py.py (4) | dep DAG + cascade |
-| mini-ork-scheduler | mini_ork/scheduler.py | test_scheduler_py.py | **win #1 active**: the public Python launcher owns the concurrent epic pool (MO_SCHED_MAX_PARALLEL); duplicate Bash and ported-Python owners retired |
-| cost_pause.sh | mini_ork/dispatch/cost_pause.py | test_cost_pause_py.py (2) | window-crossing pause + sentinel |
-
-Also landed earlier on this branch: win #3 (mo_grade_run_reward: rubric 0-8 ->
-graded reward_g, bash+python), lane-fallback hang-proofing (dispatch_with_fallback
-+ role-aware chains in executor).
-
-## REMAINING (trunk)
-- context_assembler.sh — RETIRED. `mini_ork/context_assembler.py` owns bounded
-  packs, failure/prior-run blocks, ContextNest atoms and recent sessions,
-  operator-steering rendering, active-state injection, and its fixture CLI.
-- reflection_pipeline.sh + gradient_extractor.sh — RETIRED. Native reflection,
-  gradients, routing, and standalone contracts own the complete surface.
-- top-level CLI and execute — closed on 2026-07-20. `bin/mini-ork` is the
-  Python launcher, `mini-ork execute` routes in-process, and the retired
-  `bin/mini-ork-execute` implementation is absent.
-- llm-dispatch.sh remainder: runtime review callers are closed; convert the
-  provider, telemetry, retry, artifact, and tool-grant fixtures before retiring
-  the Bash dispatcher.
-- assorted leaves: workflow_lifecycle, operator_steering, steering_checkpoint,
-  mid_node_injector, role_evolver, runs-tracker, spec-split, artifact_contract,
-  reflection-refiner, cross_epic_gradient
-
-## Fixture-retirement sweep (ADR-001 strangler-fig)
-Same-stem bash↔`_py.py` pairs split into two classes:
-- **Standalone-lib fixtures — model-(a), py gate drives LIVE bash → RETIRED:**
-  coord_gate, coord_registry_ttl, lane_router_refinements, trace_store,
-  active_state_index. Each ported its un-subsumed live-bash assertions into the
-  native parity gate before `git rm` (trace_store: query/unknown-id/write-error
-  cases; coord_gate: strict-no-conflict + live leases_held).
-- **repo_integrity_guard — DISQUALIFIED (not retired):** its fixture bundles the
-  guard (subsumed by the py gate) AND group (f), the `.githooks/pre-push`
-  README-drift tag-advisory/main-block downgrade, whose ONLY live coverage is
-  this fixture (a shell git hook, no Python port; test_pre_push_review_py.py
-  covers a different concern). `git rm` would orphan (f). Follow-up (hardening,
-  not retirement): port guard-native gaps — cold-start creates LKG, virgin
-  disabled writes nothing, not-in-worktree, slash-branch LKG sanitization.
-- **Dispatch-umbrella fixtures — DEFERRED to the llm-dispatch.sh port:**
-  provider_registry, run_artifacts, dispatch (+ telemetry/retry/tool-grant). Their
-  py gates test native `mini_ork.dispatch.*` while `lib/llm-dispatch.sh` is still
-  the runtime, so retiring now loses live-bash coverage. Retire WITH the dispatcher.

-# Artifact Graph Contracts
-
-MiniOrk workflows can declare artifact ports so an agent receives a named,
-verified input rather than discovering files by convention. The executor still
-uses the configured harness (Claude Code, Codex, Gemini, or another provider)
-for agent work; MiniOrk owns the handoff contract around that harness.
-
-## Contract
-
-Each workflow node may declare:
-
-- `outputs`: named files it must publish after successful execution.
-- `inputs`: named artifacts it requires before it can execute.
-- an edge with both `from_output` and `to_input`: the only valid producer to
-  consumer handoff.
-
-The compiler validates duplicate ports, required inputs, visibility, output-path
-ownership, and DAG readiness. At runtime, an edge is also a completion gate:
-independent ready nodes may run in parallel, but a consumer starts only after
-every parent succeeds and publishes its declared outputs. A failed parent blocks
-its descendants, including publishers. Recipes without these fields stay on the
-legacy node-order path, so the migration can be incremental.
-
-```mermaid
-flowchart LR
-  A[Harness producer] -->|publish hash manifest| L[Artifact ledger]
-  L -->|materialize declared files| T[Deterministic transform]
-  T -->|publish public output| L
-  L -->|materialize declared files| B[Harness consumer]
-  T -. system-only receipt .-> O[Operator]
-```
-
-## Run Layout
-
-For a run directory `<run>`, MiniOrk writes:
-
-```text
-<run>/
-  workspace/
-    manifests/<node>.outputs.json
-    manifests/<node>.inputs.json
-    inputs/<consumer>/<input-port>/...
-    system/<transform>/...                 # system-only receipts
-    scratch/<transform>-<seed>/...          # transform working files
-```
-
-Output manifests record the declared relative path, byte size, SHA-256, kind,
-and visibility. Before materializing an input, the ledger verifies that the
-source file still matches its published hash. A producer that does not write a
-declared output fails with `artifact_contract`.
-
-An output path belongs to exactly one workflow node. The runtime reserves
-`workspace/manifests/**` and `workspace/inputs/**` for the ledger, so recipes
-cannot overwrite its integrity metadata. `workspace/system/**` remains valid
-for declared `system_only` receipts.
-
-## Visibility
-
-`consumer` is the default visibility and can be bound to a declared consumer
-input. `system_only` may be consumed only by a deterministic `transform` node.
-It is useful for receipts such as a panel label map: operators can inspect it,
-but an LLM synthesizer cannot receive it through the artifact graph.
-
-The ledger is an application-level capability boundary, not OS isolation. A
-local harness with unrestricted filesystem access could ignore its prompt and
-read other run files. Use the configured bubblewrap runtime or an equivalent
-per-node mount policy when strict filesystem isolation is required.
-
-## Transforms
-
-Transforms are registered Python functions, not LLM nodes. They receive only
-compiler-prepared inputs and must publish their declared outputs. This is the
-shared wiring point for anonymization, redaction, normalization, extraction,
-or packaging.
-
-`panel.anonymize@v1` is the first example:
-
-1. Accepts many `reports` artifacts named `lens-*.md`.
-2. Uses a deterministic seed derived from the run ID and input hashes.
-3. Scrubs known source markers, shuffles the reports, and emits a `Response A`
-   through `Response N` markdown bundle.
-4. Writes the label map as a `system_only` artifact.
-
-## Recipe Migration
-
-1. Add an `outputs` declaration to each current producer (researcher,
-   implementer, reviewer, verifier, publisher, or transform). Keep its existing
-   output path initially. Planner, reflector, and rollback nodes cannot declare
-   outputs until they gain a publication handler.
-2. Add `inputs` to a consumer and connect them with ported edges.
-3. Move filename-specific prompt instructions to the artifact input manifest.
-4. Insert a `transform` node whenever the handoff must redact, aggregate, or
-   otherwise change visibility.
-5. Add a focused test for topology, missing/tampered artifacts, and the
-   consumer prompt boundary.
-
-`recipes/refactor-audit/workflow.yaml` is the reference migration. It binds
-five lens reports to `anonymize_panel.reports` and binds only
-`panel_responses` to `synthesizer.panel_reports`.

-# The Co-Evolve Ecosystem — Architecture
-
-*How five systems compose into one co-evolving AI-development layer: **Co-Evolve** (the shell), **mini-ork** (the brain), **ContextNest** (the memory), **TraceOtter** (the weights), and **researcher** (the R&D loop that mines new techniques). Compiled 2026-07-11. Grounds on the per-system detail in [`techniques-compendium.md`](techniques-compendium.md); this doc is the layer *above* — how the pieces fit and how the whole thing gets better over time.*
-
----
-
-## 1. The thesis
-
-Most AI-dev tooling is static after deployment: a harness calls a frontier model, and every run starts from zero. Co-Evolve is the opposite bet — **one system a team owns that gets structurally better the more it's used**, along two independent axes:
-
-- **Usage flywheel** — every task run produces traces; those traces improve routing (which model), weights (a local model), and memory (grounded context). The next run is cheaper and better.
-- **Research flywheel** — the system reads the AI-research frontier (arXiv), proposes improvements to *its own method*, proves each on held-out data, and adopts only what wins.
-
-The first flywheel compounds on *your* work. The second compounds on *the entire literature*. Neither requires a human in the loop, and every change is gated + auditable.
-
----
-
-## 2. The five components
-
-| Component | Role | Repo | One-line |
-|---|---|---|---|
-| **Co-Evolve** | The shell / product | `ps/coevolve` (Go) | The CLI + control plane a team runs; opencode-style front-end that spawns mini-ork over MCP and renders the whole loop. |
-| **mini-ork** | The brain / orchestrator | `ps/mini-ork` (bash+Python) | Task OS: classify→plan→execute→verify→reflect→improve→eval→promote, heterogeneous model lanes, GRPO routing, GEPA, the gradient + **apply loop**. |
-| **ContextNest** | The memory substrate | `ps/ContextNest` (Rust) | Turns session transcripts into an attractor-basin memory field; grades every claim against real tool events; serves grounded context back. |
-| **TraceOtter** | The weight arm | `ps/TraceOtter` (Python) | Distils execution traces into an SFT dataset and LoRA-trains a small local model; held-out-gated; JitRL continual design. |
-| **researcher** | The R&D loop | `ps/researcher` + arxiv-libwit corpus | Reads the arXiv frontier, proposes new techniques / self-improvements, and pushes them through the same held-out gate before adoption. |
-
-The rule of composition: **mechanics are per-system; decisions are shared.** mini-ork is the single place that decides (route, apply, promote); the others are specialized organs (memory, weights, research) it reads from and writes to.

-## 4. How one request flows end-to-end
-
-1. **Invoke.** A developer fires a task through **Co-Evolve** (CLI/Slack/IDE). Co-Evolve spawns **mini-ork** over MCP inside the team's own environment — no code leaves the VPC.
-2. **Prefetch memory.** Before planning, mini-ork pulls a kind-ordered **capsule** from **ContextNest** (risks → decisions → failures → … → artifacts), so the run starts grounded instead of rediscovering context.
-3. **Route.** For each node, `decide()` picks a model lane by learned **GRPO relative advantage** — sending the majority to the cheap **TraceOtter local model** and reserving frontier compute for the hard minority.
-4. **Execute + verify.** Workers run; verifier gates enforce real evidence (no "vacuous" passes). Every step lands in `execution_traces` with cost, verdict, and a scale-free `reward_g`.
-5. **Reflect + learn.** A rubric grades the run; the reflection pipeline mines **gradients** (idempotent, deduped by semantic signature); GEPA proposes prompt rewrites scored by a real **online evaluator**.
-6. **Apply (the loop that just closed).** `bin/mini-ork-apply` turns the highest-confidence gradient/GEPA suggestion into a `workflow_candidate`, scores it on held-out data, passes it through a **non-regression gate**, and either promotes it (rewrites the prompt + records a version) or quarantines it. Suggest-safe by default (`MO_APPLY_ENABLED`).
-7. **Feed back.** mini-ork tells ContextNest which memories it consumed and how the run turned out (`/agent/outcome`, EvoMem) — reweighting the memory field. TraceOtter distils the new traces into the next LoRA cycle.
-
-Net: the run got cheaper (local routing), the memory got grounded (provenance-graded), and the system got a little better (an applied improvement) — all from one task.
-
----
-
-## 5. Flywheel 1 — Usage (compounds on *your* work)
-
-Three sub-loops turning on the same `execution_traces` stream:
-
-- **Routing (mini-ork):** GRPO relative-advantage per `(objective_domain, task_class, node_type, code_region)` group, recency-weighted, shrinkage-damped. `preferred_lane` shifts toward whichever lane beats its peers → cheaper routing over time.
-- **Weights (TraceOtter):** traces → action-grounded route labels + MemP skills → redact/quality-gate → single-epoch LoRA on Qwen3-4B → **gate on held-out route accuracy, not train loss** (72.4% vs 0% base). JitRL will make this continual (frozen model + additive logit memory, ~30× cheaper, no forgetting).
-- **Memory (ContextNest):** transcripts → attractor basins + fragments; every self-reported claim **graded against real tool receipts** (a "tests passed" claim that a Bash receipt contradicts is down-weighted). Retrieval score = `cosine · decay · kind · density · trust`; EvoMem outcome feedback nudges what surfaced.
-
-The **apply loop** is what makes these *act*: without it, all three merely *diagnose*. With it, a learned improvement becomes an applied prompt/recipe/lane change through a non-regression gate.
-
-## 6. Flywheel 2 — Research (compounds on *the literature*)
-
-This is the **researcher** organ — the second, rarer flywheel:
-
-1. **Read the frontier.** The researcher queries the arxiv-libwit corpus (~147K papers) for techniques relevant to the system's own weak spots (surfaced by the trace scorecard: which recipe/node underperforms).
-2. **Propose a method change.** A concrete, scoped self-improvement — a new routing rule, a workflow mutation, a dedup strategy, a reward shape — grounded in a specific paper.
-3. **Gate it.** The *same* held-out eval gate the apply loop uses. A proposed change is adopted only if it beats the current method on held-out data — **every change traceable to the paper it came from.**
-4. **Adopt.** Winners flow into mini-ork's self-improvement machinery (as a candidate → promote), exactly like a usage-derived gradient.
-
-The two flywheels share one gate and one apply path — the research loop is "just another source of candidates," which is why the whole thing stays auditable and non-regressive. *(Build order: the eval gate is the prerequisite for both — see the arxiv-driven-R&D-loop and eval-in-run-flow research docs.)*
-
----
-
-## 7. The contracts between organs
-
-- **mini-ork ⇄ ContextNest:** prefetch (`cn_retrieve`, `/prompt-context/capsule`) in; `/agent/outcome` (consumed-atoms + result) out. Side-effect-light — outcome feedback only reweights metadata retrieval already reads.
-- **mini-ork ⇄ TraceOtter:** `execution_traces` are the shared substrate; TraceOtter reads them, trains, and publishes a local model the router dispatches to.
-- **mini-ork ⇄ researcher:** the trace scorecard says *what to research*; the researcher returns *candidate method changes* that re-enter the promote pipeline.
-- **Co-Evolve ⇄ everything:** MCP to mini-ork; read-only panels over all three organs' state (run/cost/router/context/memory). The one process a customer runs.
-
-All decisions route through mini-ork's `decide()`/apply/promote — so the policy is **shared once** across consumers (eng-team, book-gen, …) via `objective_domain` partitioning, while each organ's mechanics stay native.
-
----
-
-## 8. Deployment & sovereignty
-
-The whole ecosystem runs **inside the customer's environment/VPC**: traces, memory, and the tuned local model never leave. Frontier calls (the hard minority) route through the customer's *own* provider account — no third-party proxy. This is the moat that is also a compliance unlock: the per-customer trace corpus + tuned weights make leaving costly (revert to day-1 frontier pricing on months of retraining), and air-gapped operation satisfies the regulated-DACH mandate. (Positioning detail: `internal-docs/strategy/`.)
-
----
-
-## 9. Honest state (what's real vs in-flight)
-
-- **Real + shipped:** mini-ork loop + GRPO routing; ContextNest basins + provenance grading + EvoMem feedback; TraceOtter distil→LoRA at 72.4% held-out; the **learn→apply loop (merged 2026-07-11)** so GEPA/gradients now actually change prompts; Co-Evolve control-plane wiring.
-- **Designed, not yet wired:** TraceOtter JitRL continual learning; the researcher R&D flywheel is ~70% existing mini-ork parts but its held-out eval gate for method-changes must be built first; ContextNest's elegant "neural-field/resonance" canon layer is largely dormant (basins are live, the deeper field theory is scaffolding).
-- **Modeled, not proven on a customer:** the 84% token-cost reduction and quality-parity numbers are internal modeling / held-out, not yet validated on an external workload.
-
-The line to hold: this is an *outer system* — general, memory-backed, multi-lane, self-improving, deployable — whose *inner* self-improvement loop just became real. The compounding curve is the gating artifact; everything above exists to make that curve go up on both usage and research.
-
----
-
-# Appendix A — Technique deep dives (worked examples)
-
-*Each deep dive has three parts: **the product story** (what it buys the customer — say this to a VC), **the mechanism** (the real code, `file:line`), and **a worked example** (real numbers walked through). These are the load-bearing techniques; if a technical partner asks "but how does it actually work," this is the answer.*

-## A1 — How routing picks a model lane (cost-aware contextual bandit)
-
-> **Naming note (accuracy):** the code and older docs call this "GRPO," but it is a **cost-aware contextual bandit**, not the GRPO algorithm. GRPO samples G responses from *one trainable policy* and does a gradient weight update; routing here picks *one lane* per task among *heterogeneous closed-API models* (no shared weights, no gradients) and updates a table. It borrows exactly one idea from GRPO — the group-relative baseline — and, since PR #163, supplements it with a persistent single-sample baseline so it no longer even needs a group. See `internal-docs/research/2026-07-11-cost-efficient-grpo-learning.md`.
-
-
-### The product story
-Every coding task runs through several steps (plan, implement, review, verify). For each step, the system decides **which model to use** — a cheap local model, a mid-tier one (Kimi/MiniMax), or a frontier one (Opus/Codex). Instead of a human hard-coding "use GPT for review," the system **learns, from your own runs, which model is actually best at each kind of step on your codebase** — and it keeps adapting as models and prices change. The result: work steadily shifts to whichever model wins on *your* work, cutting cost while holding quality, with nobody tuning anything.
-
-The subtle-but-crucial part (and the part a technical VC will appreciate): it **compares models head-to-head on the same task**, not on their raw scores. A model that only ever gets handed easy tasks would look great on absolute score; grading it *relative to the other models on the identical task* cancels out task difficulty, so a model is only credited when it genuinely beats its peers. That's the "GRPO" (Group-Relative) idea, borrowed from RL post-training and applied to model routing.
-
-### The mechanism
-Entry path: `mini_ork/cli/execute.py` (`_mo_policy_route_lane`, policy `MO_ROUTING_POLICY=learning_governed`) → `_mo_learning_governed_lane` (`:347`) → `decide()` (`lib/decision_service.sh:80`) → `lane_router_preferred_lane` → `mini_ork/lane_router.py::preferred_lane` (`:286`). The learning itself is `recompute_advantages` (`lane_router.py:31`), run during reflect.
-
-The computation (`lane_router.py:117-283`), per the reward signal `reward_g` (a scale-free, direction-normalized run quality in `[−1,+1]`):
-1. **Group** every past trace by `(objective_domain, task_class, node_type, code_region)` — traces that competed on the *same kind of work* (`:132`). Groups of 2+ get a within-group relative advantage; **single-lane runs are no longer skipped** — since PR #163 they update a persistent per-slice baseline (`lane_slice_baseline`, SPO-style) and score `advantage = reward − running_slice_mean`, so the router learns from ordinary 1× runs, not only from panel/bake-off slices (gated by `MO_ROUTER_SINGLE_SAMPLE`, default on).
-2. **Weighted group mean** `wmean` with a **14-day recency half-life** so stale evidence fades (`:127-129, 147`).
-3. **Per-lane advantage** = `lane_mean − wmean` (`:164`) — the lane's average minus the group's average. Positive = beats its peers on this slice.
-4. **Cost tie-break**: when quality is flat (all scores equal), add a small bonus to the *cheaper* lane (`0.1 − 0.2·normalized_cost`, `:150-155`).
-5. **Shrinkage** `n/(n+5)` damps low-sample lanes so a lane doesn't win on one lucky run (`:166`).
-6. **EMA blend** with the prior value (`α=0.30`, `:217-226`) so the policy moves smoothly, not jerkily.
-7. **Decayed defect penalty**: a lane that caused a bug in a code region gets a time-decaying penalty *for that region* (`:185-215`).
-8. Results are written to three tables at increasing specificity: `lane_region_advantage`, `lane_domain_advantage`, `agent_performance_memory`.
-
-At routing time, `preferred_lane` (`:286`) selects a lane that has enough samples (`MO_LEARNING_MIN_SAMPLES=3`), cascading **region → domain → global** (`:295-330`) — most specific track record first, then falls back. Since PR #163, selection is **UCB** (`z_score_advantage + C·√(2·lnN/n)`, `MO_ROUTER_UCB_C` default 0.5) rather than raw argmax, so an under-sampled promising lane can be tried over a marginally-better well-sampled one (`MO_ROUTER_UCB_C=0` restores the legacy argmax). Cold-start safe: if nothing clears the floor, it returns empty and `decide()` uses the configured default lane (never invents one). Exploration also lives in `decide()`: an **ε-draw** (10%) that, when the bandit is on, reroutes to the **least-sampled** eligible lane (highest uncertainty) instead of uniform-random. Every routing decision can log its propensity (`route_source/route_explore/route_score`), and `scripts/router_replay_eval.py` replays the logs to check the new selector beats the legacy rule (measured +0.09 win-rate on the current corpus).
-
-This is a **contextual bandit**, not GRPO or off-policy RL: there is no importance-sampling correction, because off-policy estimators (IPS/DR) are unreliable under near-deterministic logging (2509.00648). The UCB exploration is what gradually buys the counterfactual coverage instead.
-
-### Worked example
-Task: `code_fix`, step: `implementer`, domain: `code-delivery`. Over the last 14 days three lanes ran this step across many task instances. On each instance the lanes are graded *relative to each other*; here is one representative instance's rubric-normalized `reward_g` plus the 14-day aggregate:
-
-| Lane | avg reward_g (its runs) | group mean (all lanes) | advantage = lane − group | samples | after shrinkage ×n/(n+5) |
-|---|---:|---:|---:|---:|---:|
-| **minimax** | 0.667 | 0.50 | **+0.167** | 12 | +0.167 × 12/17 = **+0.118** |
-| **codex** | 0.625 | 0.50 | +0.125 | 7 | +0.125 × 7/12 = +0.073 |
-| **kimi** | 0.125 | 0.50 | −0.375 | 6 | −0.375 × 6/11 = −0.205 |
-
-After the EMA blend with last cycle's values, `agent_performance_memory` holds roughly: minimax **+0.11**, codex +0.07, kimi −0.20. Next time an `implementer` node fires on a `code_fix` task, `preferred_lane` runs `SELECT … ORDER BY relative_advantage DESC` with `runs_count ≥ 3` → **minimax wins**, and the node dispatches to minimax. If minimax and codex had *tied* on quality, the cost tie-break would send it to whichever is cheaper. If minimax had recently caused a bug in `src/auth/`, the region penalty would down-weight it *for that module only*, and codex might win there while minimax still wins elsewhere.
-
-**Why the VC cares:** this is the mechanism behind "cost falls while quality holds, and it compounds." Nobody wrote a routing table; the system derived it from the customer's own traces, and it self-corrects weekly. That per-customer routing policy *is* the moat — a competitor can copy the idea but not the months of your traces it was trained on.

-## A2 — How gradients turn failures into fixes
-
-### The product story
-The system watches its own agents work and, when something goes wrong, **writes down the fix in plain English** — e.g. "the reviewer is approving code without reading the files; make it cite evidence before giving a verdict." It generates thousands of these observations, **dedupes them into a handful of real lessons**, and (via the apply loop, A4) tests and applies the good ones — so the system's own prompts get better over time **without a human editing them**. To a customer: "it debugs and improves itself, and every improvement is traceable to the runs that motivated it."
-
-### The mechanism
-A "gradient" is a **textual improvement signal** (TextGrad-style), stored in `gradient_records`: `{target, signal, suggested_change, confidence, evidence(trace_id)}`. The Python reflection pipeline (`mini_ork/cli/reflect.py` + `mini_ork/learning/reflection_pipeline.py`) does: **extract** (an LLM reads low-reward traces and proposes 0–5 gradients each) → **dedup** → **cluster** → hand off to the apply loop.
-
-Three properties that make it production-safe (shipped 2026-07-11):
-- **Idempotent extraction:** a per-trace watermark in `mini_ork/learning/gradient_extractor.py` skips any trace already mined and excludes framework-internal `__reflect__` traces — so re-running reflect over an overlapping window doesn't re-generate the same gradient. (Before this fix: 9,777 gradients from only 1,603 traces — a 6× duplicate pile.)
-- **Semantic-signature dedup** (`mini_ork/learning/reflection_pipeline.py`): near-identical gradients that differ only in trace-specific noise (durations like "2.7min", costs like "$1.62", trace-ids) are normalized to a **semantic signature** and collapsed. This is why 172 differently-worded "reviewer must cite evidence" observations become **one** lesson.
-- **Confidence + evidence:** each gradient carries a 0–1 confidence and the trace-ids that produced it, so the apply loop can rank and audit.
-
-### Worked example
-Real gradients pulled from a live DB, all targeting `agent.reviewer.prompt`:
-
-| signal (what the system observed) | suggested_change (the fix, in plain English) | confidence |
-|---|---|---:|
-| "Reviewer issued ESCALATE after 2.7min/$1.62 with files_read=[]" | "Require the reviewer prompt to emit a structured evidence block (files_inspected[], diff_hunks) before any verdict." | 0.95 |
-| "Reviewer returned needs_revision with zero files_read and zero tool_calls" | "Reviewer prompt must mandate explicit file inspection before a verdict." | 0.92 |
-| "Reviewer returned a pass verdict despite reading no files" | "Require the reviewer to cite concrete evidence from the changed files/diff/tests." | 0.92 |
-
-There were ~57 more phrased differently. The dominant, high-confidence theme is a single real bug — **agents giving verdicts without reading the code** ("theater"). Semantic dedup collapses all ~60 into one lesson: *"reviewer must cite evidence before verdict."* That one deduped, high-confidence gradient is what flows into the apply loop (A4), gets tested on held-out reviews, and — if it doesn't regress — rewrites the reviewer prompt to require an evidence block.
-
-**Why the VC cares:** this is a self-debugging system with an audit trail. It found, in its own logs, the exact failure mode ("reviewers not reading the code") that a human would take weeks to notice, and it fixes it under a gate. The diagnosis quality is high; the apply loop (A4) is what turns diagnosis into a shipped improvement.

-
-## A3 — How GEPA improves a prompt (reflective evolution)
-
-### The product story
-Beyond one-line fixes, the system can **rewrite an entire prompt** for a role (say, the planner) by looking at where it failed and proposing a better version — then keeping the new prompt **only if it measurably beats the old one** on held-out tasks. It's cheaper than RL fine-tuning (a handful of evaluations, not thousands of rollouts) and every accepted change is proven, not hoped.
-
-### The mechanism
-`mini_ork/optimize/gepa.py` (Genetic-Pareto reflective optimizer). Loop: keep the best prompt on a Pareto front → draw a minibatch → build a "reflective dataset" from the failures → an LLM (real lane via `MO_OPTIMIZER_MODEL`, default minimax) proposes a rewrite of one component → **strict-improvement gate on the minibatch**: keep only if `sum(new) > sum(parent)` (`:204`) → then a full eval. The fatal historical bug (fixed 2026-07-11): the evaluator could only score prompts by hash-lookup of past runs, so a *new* prompt always tied its parent and was always rejected. The fix is a real **online evaluator** `held_out_score()` that actually runs and scores the candidate — so the gate is winnable.
-
-### Worked example
-Seed reviewer prompt scores **0.61** on held-out reviews. GEPA reads the failures (the "no evidence" theme), proposes: *"…before any verdict, list the files you inspected and quote the diff hunk that supports your finding; if you inspected nothing, return REQUEST_CHANGES."* On the minibatch the new prompt scores **5.9 vs 4.5** for the parent → accepted → full eval **0.74 > 0.61** → it goes on the Pareto front. A later over-strict mutation scores **5.8 vs 6.0** → rejected, no full eval spent (that's the ~35× rollout saving vs evaluating every idea fully).
-
----
-
-## A4 — How the apply loop ships a change (the loop that closes the system)
-
-### The product story
-This is what makes all of the above *real* instead of a pile of suggestions: the system takes its best learned improvement, **tests it on held-out work, checks it doesn't make anything worse, and only then applies it** — rewriting the actual prompt and recording a reversible version. It's off by default (suggest-only) so nothing changes a customer's system without the gate passing. To a VC: "it doesn't just learn — it safely ships its own improvements, with a non-regression guarantee and a rollback."
-
-### The mechanism
-`bin/mini-ork-apply` + `lib/apply.sh` (migration `0048_apply_attempts`): **pick** the highest-confidence candidate (from `pattern_records` / `emergent_patterns` / `gradient_records`, matched by task_class/role) → **materialize** a `workflow_candidates` row → **score** it (online eval `held_out_score`, or a mock in tests) → **non-regression gate** (`apply_evaluate_gate`: promote only if `utility_after ≥ utility_before`; else quarantine) → **promote** = rewrite the prompt file + write a `version_registry` row (reversible), or **quarantine** with an audited reason. Guards: `MO_APPLY_ENABLED` (master switch, default OFF), `MO_APPLY_DRY_RUN` (write nothing), `MO_APPLY_NONREGRESSION_DELTA` (how much regression, if any, is tolerable).
-
-### Worked example
-The deduped gradient from A2 ("reviewer must cite evidence") is picked. A candidate reviewer prompt is materialized. The online evaluator scores it **0.74** vs the current prompt's **0.50** baseline → `utility_delta = +0.24 ≥ 0` → **promoted**: the reviewer prompt file is rewritten to require an evidence block and a `version_registry` row is recorded. If the same evaluator had instead scored the candidate **0.35** (a regression), the gate returns **quarantined** with the rationale "non-regression failed (0.35 < 0.50)", the prompt is left untouched, and the attempt is logged for audit. Net: a failure the system observed in its own logs became a proven, reversible prompt improvement — automatically, under a gate.
-
-**The whole chain, in one line for the pitch:** *a run fails → the system writes down why (gradient) → dedupes thousands of these into one real lesson → GEPA/apply proposes a fix → it's proven on held-out work under a non-regression gate → the prompt is rewritten and versioned → the next run is better.* That is the compounding curve, mechanized.

-# GEPA در mini-ork — بهینه‌سازی بازتابی پرامپت، به زبان ساده
-
-*این سند توضیح می‌دهد GEPA در سیستم ما دقیقاً چطور کار می‌کند: چه مشکلی را حل می‌کند، حلقه‌اش چه گام‌هایی دارد، و در mini-ork چطور به تاریخچهٔ اجراها وصل می‌شود. با یک مثال کامل قدم‌به‌قدم. مرجع کد: `mini_ork/optimize/gepa.py` و `mini_ork/optimize/miniork_adapter.py`.*
-
----
-
-## GEPA چیست و چه دردی را درمان می‌کند؟
-
-**GEPA** یعنی «تکامل ژنتیکی-پارتو» (Genetic-Pareto). یک بهینه‌ساز **پرامپت** است، نه بهینه‌ساز وزن مدل. کارش این است: پرامپت یک نقش (مثلاً پرامپت داورِ کد) را طوری بازنویسی کند که کیفیت خروجی بالا برود.
-
-راه معمول برای بهتر کردن رفتار مدل، یادگیری تقویتی (RL / GRPO) است که **هزاران بار اجرا** لازم دارد و سیگنالش فقط یک عدد خشک است. ایدهٔ کلیدی GEPA این است:
-
-> زبان طبیعی رسانهٔ یادگیری غنی‌تری از یک پاداش عددی است. به‌جای اینکه از هزاران اجرا یک گرادیان عددی دربیاوریم، بگذاریم مدل **به شکست‌ها نگاه کند، درباره‌شان فکر کند، و پرامپت را بازنویسی کند** — و فقط تغییری را نگه داریم که واقعاً بهتر شد.
-
-نتیجه: کیفیت هم‌سطح یا بهتر از RL، اما با تعداد اجرای بسیار کمتر.
-
-نکتهٔ مهم دربارهٔ جایگاهش در سیستم ما: GEPA در mini-ork **فقط پیشنهاد می‌دهد** و هرگز خودکار اعمال نمی‌شود؛ فقط وقتی `MO_OPTIMIZER=gepa` تنظیم شده باشد در مرحلهٔ بازتاب (`bin/mini-ork-reflect`) فعال می‌شود.
-
----
-
-## GEPA به‌طور کلی چطور کار می‌کند (مستقل از سیستم ما)
-
-GEPA از مقالهٔ Agrawal و همکاران (۲۰۲۵، arXiv:2507.19457) می‌آید و روشی عمومی برای بهینه‌سازی «برنامه‌های زبانی مرکب» است — یعنی سیستم‌هایی که از چند فراخوانی مدل با چند پرامپت ساخته شده‌اند. سه ایدهٔ اصلی که اسمش هم از آن‌ها آمده:
-
-**۱. بازتابی (Reflective) — یاد گرفتن از زبان، نه فقط از عدد.** روش معمول RL از یک پاداش عددی خشک گرادیان می‌سازد. GEPA به‌جای آن **کل مسیر متنی اجرا** را نگه می‌دارد — استدلال مدل، فراخوانی ابزارها، پیام‌های خطا، بازخورد ارزیاب — و از یک مدل می‌خواهد به این متن نگاه کند، تشخیص دهد **چرا** خراب شد، و پرامپت را اصلاح کند. حرف اصلی مقاله: زبان طبیعی رسانهٔ یادگیری بسیار غنی‌تری از یک عدد تنهاست.
-
-**۲. ژنتیک (Genetic) — جمعیت، جهش، و تلفیق.** یک «جمعیت» از نسخه‌های پرامپت نگه‌داری می‌شود. نسخه‌های جدید با دو عملگر ساخته می‌شوند: **جهش** (بازنویسی بازتابیِ یک جزء) و **تلفیق/کراس‌اوور** (ترکیب درس‌های مکملِ دو نسخهٔ متفاوت که هرکدام یک چیز را خوب یاد گرفته‌اند).
-
-**۳. پارتو (Pareto) — حفظ تنوع به‌جای فقط «بهترین».** ترفند کلیدی این‌جاست. اگر فقط «تنها بهترین» را نگه داری، تنوع می‌میرد و در یک بهینهٔ محلی گیر می‌کنی. GEPA به‌جای آن **جبههٔ پارتو** را نگه می‌دارد: نسخه‌هایی که هرکدام دست‌کم روی **یک نمونهٔ آموزشی** بهترین‌اند. والدِ هر تکرار از این جبهه انتخاب می‌شود، پس استراتژی‌های «متخصص» متنوع زنده می‌مانند و بعداً می‌شود بازترکیبشان کرد.
-
-**نتیجهٔ مقاله:** کیفیت هم‌سطح یا بهتر از یادگیری تقویتی (GRPO)، اما با تا **۳۵ برابر اجرای کمتر** — چون بازتاب روی چند اجرا بسیار ارزان‌تر از هزاران رول‌اوت RL است. برای برنامه‌های چندماژولی، GEPA حتی می‌تواند تشخیص دهد **پرامپت کدام ماژول** را اصلاح کند (اسناد اعتبار در سطح ماژول).
-
-> **تفاوت مهم با پیاده‌سازی فعلی ما:** در مقاله ارزیاب **آنلاین** است — نسخهٔ پرامپت جدید را واقعاً روی وظایف اجرا و نمره می‌دهد، و همین است که اجازه می‌دهد یک ایدهٔ نو واقعاً سنجیده و پذیرفته شود. در سیستم ما (فعلاً) ارزیاب **آفلاین** است و فقط پاداش‌های گذشته را از روی هشِ پرامپت نگاه می‌کند؛ پس نمی‌تواند یک پرامپت کاملاً جدید را نمره بدهد. این محدودیتِ اصلی نسخهٔ فعلی ماست (پایین‌تر با جزئیات).
-
----
-
-## دو مفهوم پایه
-
-**۱. کاندیدا (candidate).** یک پرامپت، در قالب یک دیکشنری از «اجزا». مثلاً:
-
-```json
-{
-  "reviewer_system": "تو یک داور کد هستی. باگ‌ها را پیدا کن.",
-  "reviewer_rubric": "درستی، خوانایی، تست."
-}
-```
-
-هر کلید یک «جزء» (component) است که می‌شود جداگانه بازنویسی‌اش کرد.
-
-**۲. جبههٔ پارتو (Pareto front).** یک لیست از بهترین کاندیداهایی که تا حالا دیده‌ایم. در حالت تک‌هدفه (که فعلاً ما داریم) ساده می‌شود به «بهترین کاندیدا را نگه دار». ساختار داده برای حالت چندهدفه (کیفیت در برابر هزینه) آماده است ولی هنوز فعال نیست (`ParetoFront`, خط ۵۴).

-## حلقهٔ GEPA — گام به گام
-
-تابع اصلی `optimize()` (خط ۱۴۲) این کارها را می‌کند:
-
-**آماده‌سازی (seed):**
-- کاندیدای اولیه (seed) را روی **کل دستهٔ داده** ارزیابی کن و نمرهٔ پایه را بگیر. این را روی جبههٔ پارتو بگذار (خط ۱۶۸–۱۷۰).
-- این یک بار ارزیابی کامل است ولی جزو «بودجه» حساب نمی‌شود.
-
-**هر تکرار (تا وقتی بودجه تمام شود — پیش‌فرض ۴ تکرار):**
-
-۱. **انتخاب والد:** بهترین کاندیدای روی جبهه را بردار (خط ۱۷۶).
-
-۲. **انتخاب یک جزء:** یکی از اجزای پرامپت را برای بازنویسی انتخاب کن (خط ۱۷۷). فقط **یک** جزء در هر تکرار — این عمدی است تا بتوان فهمید کدام تغییر مؤثر بود.
-
-۳. **کشیدن یک نمونهٔ کوچک (minibatch):** به‌جای کل داده، فقط ۸ مثال تصادفی بردار (خط ۱۷۹–۱۸۳). این‌جا هزینه صرفه‌جویی می‌شود.
-
-۴. **ارزیابی والد روی نمونهٔ کوچک:** ببین والد روی این ۸ مثال چند می‌گیرد و ردپاها (traces) را نگه دار (خط ۱۸۶).
-
-۵. **ساختن «دیتاست بازتابی»:** از سه‌تایی‌های (مثال، نمره، ردپا) یک بستهٔ بازخورد بساز که می‌گوید کجاها ضعیف بود (`make_reflective_dataset`, خط ۱۹۴). این همان «شواهد شکست» است که به مدل می‌دهیم.
-
-۶. **بازتاب و جهش:** پرامپت فعلی + بازخورد را به یک مدل بده و بخواه **فقط همان یک جزء** را بازنویسی کند تا شکست‌ها را برطرف کند (`reflect_on_component`, خط ۱۰۱). خروجی باید JSON تمیز باشد؛ اگر مدل چیز قابل‌استفاده‌ای نداد، این تکرار رد می‌شود (خط ۱۹۹–۲۰۰).
-
-۷. **دروازهٔ بهبود سخت‌گیرانه:** کاندیدای جهش‌یافته را **روی همان نمونهٔ کوچک** ارزیابی کن. **فقط اگر مجموع نمره‌اش از والد بیشتر شد** جلو برو؛ وگرنه دورش بینداز (خط ۲۰۳–۲۰۵). این قلب صرفه‌جویی است: تغییرِ رد‌شده هیچ‌وقت ارزیابی کامل نمی‌گیرد.
-
-۸. **پذیرش:** حالا که روی نمونهٔ کوچک بهتر شد، **یک بار روی کل داده** ارزیابی‌اش کن، روی جبههٔ پارتو بگذار، و شمارندهٔ ارزیابی کامل را یکی زیاد کن (خط ۲۰۷–۲۱۹).
-
-**پایان:** بهترین کاندیدای روی جبهه را برگردان (خط ۲۲۱).
-
-### چرا این ارزان است؟
-
-«بودجه» یعنی حداکثر تعداد تکرار. فقط جهش‌های **پذیرفته‌شده** ارزیابی کامل می‌گیرند. با بودجهٔ ۴ و ردِ بیشتر جهش‌ها، تو ~۸ ارزیابی نمونه‌کوچک + ۰ تا ۴ ارزیابی کامل خرج می‌کنی — همان ادعای «۳۵ برابر صرفه‌جویی» نسبت به حالتی که هر جهش را روی کل داده تست کنی (خط ۵–۹).
-
----
-
-## GEPA در mini-ork چطور به تاریخچهٔ اجراها وصل می‌شود؟
-
-پل بین GEPA و سیستم ما `MiniOrkGepaAdapter` است (`miniork_adapter.py`, خط ۳۰). این آداپتور **آفلاین** کار می‌کند — یعنی مدل واقعی را دوباره اجرا نمی‌کند، بلکه از پاداش‌های ثبت‌شدهٔ گذشته استفاده می‌کند:
-
-- **`_load_full_batch`:** آخرین ردیف‌های `execution_traces` را برای یک `task_class` می‌خواند و هر ردیف را یک «مثال» می‌کند. کلید تطبیق، `prompt_version_hash` است و سیگنال نمره، ستون `reward_value`.
-- **`evaluate()`:** هش کاندیدا را با `reward_value`های ذخیره‌شده تطبیق می‌دهد. اگر برای یک هش داده‌ای نبود، **میانگین والد** را برمی‌گرداند — هیچ‌وقت عدد جعل نمی‌کند.
-- **`make_reflective_dataset()`:** تکه‌های `verifier_output` و `reviewer_verdict` (تا ۲۴۰ کاراکتر) را به‌عنوان بازخورد سرِ هم می‌کند.
-- **`run_suggestion()`:** نتیجه را در قالب یک رکورد شبیه `pattern_records` بسته‌بندی می‌کند: `{suggested_promotion_type: "prompt_change", pattern_id: "gepa-<recipe>-<ts>", evidence_trace_ids, candidate, validity}`. بودجه بین ۱ تا ۸ محدود می‌شود (`MO_OPTIMIZER_BUDGET`).
-
-پس در سیستم ما GEPA یعنی: «از پاداش‌های واقعی اجراهای گذشته یاد بگیر، یک بازنویسی پرامپت پیشنهاد بده، ولی تصمیم اعمالش با گِیت ترفیع و انسان است.»
-
-> **⚠️ محدودیت فعلی (صادقانه):** نسخهٔ فعلی هنوز یک «داربست» است، نه یک بهینه‌ساز کامل. دو دلیل: (۱) گام جهش با مدل `stub` صدا زده می‌شود، نه یک مدل واقعی — پس در عمل بازنویسی واقعی تولید نمی‌شود؛ (۲) چون ارزیاب آفلاین است، یک پرامپت **کاملاً جدید** هش تازه‌ای دارد که هیچ ردیف پاداشی برایش در دیتابیس نیست، و آداپتور به «میانگین والد» برمی‌گردد — یعنی دروازهٔ «بهبود سخت‌گیرانه» تقریباً هرگز یک جهش را نمی‌پذیرد. برای اینکه GEPA واقعاً چیزی را بهتر کند، به یک **ارزیاب آنلاین** (اجرای پرامپت جدید روی وظایف واقعی) و یک **مدل واقعی برای جهش** نیاز داریم. مثال زیر رفتار *ایده‌آل* (مثل مقاله) را نشان می‌دهد، نه چیزی که پیاده‌سازی آفلاین فعلی تولید می‌کند.
-
----
-
-## مثال کامل قدم‌به‌قدم *(رفتار ایده‌آل با ارزیاب آنلاین)*
-
-فرض کن می‌خواهیم پرامپت **نقش داورِ کد** را برای `task_class = code_fix` بهتر کنیم.
-
-**کاندیدای اولیه (seed):**
-```json
-{ "reviewer_system": "تو داور کد هستی. بگو کد قبول است یا نه." }
-```
-
-**گام ۰ — ارزیابی پایه:** روی ۲۰ اجرای گذشتهٔ code_fix، میانگین `reward_value` این پرامپت = **۰٫۶۱**. روی جبهه می‌رود.
-
-**تکرار ۱:**
-- والد = همان seed. جزء انتخابی = `reviewer_system`.
-- نمونهٔ کوچک = ۸ اجرا. نمرهٔ والد روی این ۸ تا = مجموع **۴٫۵**.
-- **دیتاست بازتابی** از ردپاها می‌گوید: «در ۳ مورد، داور کد را قبول کرد ولی تست‌ها واقعاً fail بودند؛ داور تست‌ها را چک نکرده بود.» (این از `verifier_output` می‌آید.)
-- **بازتاب:** مدل با دیدن این بازخورد پیشنهاد می‌دهد:
-```json
-{ "reviewer_system": "تو داور کد هستی. قبل از هر تأییدی، حتماً بررسی کن که تست‌های مرتبط اجرا شده و پاس شده‌اند؛ اگر شاهد اجرای تست نیست، رد کن و بگو چه تستی لازم است." }
-```
-- **دروازه (روی همان ۸ نمونه):** نمرهٔ کاندیدای جدید = **۵٫۹** > ۴٫۵. ✅ قبول.
-- **ارزیابی کامل:** روی هر ۲۰ اجرا، میانگین = **۰٫۷۴**. روی جبهه می‌نشیند و والد قبلی را کنار می‌زند. یک «ارزیابی کامل» خرج شد.
-
-**تکرار ۲:**
-- والد = نسخهٔ جدید (۰٫۷۴). جزء = `reviewer_system`.
-- بازخورد این بار می‌گوید داور گاهی زیادی سخت‌گیر شده و کدهای درست را هم رد می‌کند.
-- بازتاب یک بازنویسی پیشنهاد می‌دهد که «فقط وقتی شاهد fail هست رد کن».
-- **دروازه:** نمرهٔ جدید روی نمونهٔ کوچک = ۵٫۸، ولی والد ۶٫۰ بود → **کمتر شد**. ❌ رد. هیچ ارزیابی کاملی خرج نشد.
-
-**تکرار ۳ و ۴:** مشابه؛ فرض کن یکی قبول می‌شود و به ۰٫۷۷ می‌رسد، یکی رد.
-
-**خروجی نهایی:** بهترین کاندیدا با نمرهٔ **۰٫۷۷** (از ۰٫۶۱ پایه) + فهرست جهش‌های پذیرفته‌شده. کل هزینه: ۴ ارزیابی نمونه‌کوچک + ۲ ارزیابی کامل — نه ۴ ارزیابی کامل.
-
-این پیشنهاد به‌شکل یک رکورد `prompt_change` ذخیره می‌شود؛ **اعمال نمی‌شود** مگر اینکه از گِیت ترفیع رد شود.
-
----
-
-## جمع‌بندی در سه خط
-
-۱. GEPA پرامپت‌ها را با **نگاه‌کردن به شکست‌ها و بازنویسی بازتابی** بهتر می‌کند، نه با هزاران اجرای RL.
-۲. صرفه‌جویی از این می‌آید که فقط جهش‌هایی که **روی یک نمونهٔ کوچک** بهتر شدند، ارزیابی کامل می‌گیرند (دروازهٔ بهبود سخت‌گیرانه + جبههٔ پارتو).
-۳. در mini-ork آفلاین از `reward_value` اجراهای گذشته یاد می‌گیرد و فقط **پیشنهاد** می‌دهد؛ تصمیم نهایی با گِیت ترفیع است.

-# راهنمای سیستم: mini-ork · TraceOtter · ContextNest
-
-*یک توضیح روان و قابل‌فهم از کل سامانه و تکنیک‌هایی که در آن به‌کار رفته است. هدف این است که کسی که کد را نخوانده هم بتواند تصویر کامل و درست از «چطور این سیستم یاد می‌گیرد» به‌دست بیاورد. جزئیات دقیق‌تر و ارجاع خط‌به‌خط کد در نسخهٔ انگلیسی (`techniques-compendium.md`) آمده است.*
-
----
-
-## تصویر کلی: سه سیستم، یک حلقه
-
-کل سامانه از سه بخش تشکیل شده که روی یک جریان مشترک از «ردپاها» (traces) کار می‌کنند:
-
-- **mini-ork** — مغز و ارکستریتور (هماهنگ‌کننده). کارها را دسته‌بندی می‌کند، برنامه می‌ریزد، اجرا می‌کند، وارسی می‌کند، و مهم‌تر از همه **یاد می‌گیرد که هر کار را به کدام مدل بسپارد**.
-- **TraceOtter** — بازوی «آموزش وزن‌ها». از روی کارهایی که قبلاً انجام شده، یک مدل محلی کوچک را **آموزش** می‌دهد تا ارزان‌تر و اختصاصی‌تر شود.
-- **ContextNest** — حافظهٔ بلندمدت. گفتگوها و اجراها را به «خاطره» تبدیل می‌کند، صحت هر ادعا را با شواهد واقعی می‌سنجد، و در اجرای بعدی این حافظه را در اختیار مغز می‌گذارد.
-
-**حلقهٔ اصلی:** یک کار اجرا می‌شود ← ردپای هر قدم ثبت می‌شود ← ContextNest از آن حافظه می‌سازد و TraceOtter از آن مدل آموزش می‌دهد و mini-ork سیاست مسیریابی‌اش را به‌روز می‌کند ← همهٔ این‌ها به تصمیم بعدی برمی‌گردند. سه «چرخ‌طیار» (flywheel) که همه روی یک جریان داده می‌چرخند: **مسیریابی، وزن‌ها، حافظه**.

-## بخش الف — mini-ork: هماهنگی و یادگیری مسیریابی
-
-### حلقهٔ جهانی کار
-
-هر کار از یک زنجیرهٔ ثابت عبور می‌کند: **دسته‌بندی ← برنامه‌ریزی ← اجرا ← وارسی ← بازتاب ← بهبود ← ارزیابی ← ترفیع**.
-
-- **دسته‌بندی (classify):** با اسکن کلیدواژه/الگو تشخیص می‌دهد این کار از چه «نوعی» است (مثلاً رفع باگ، ویرایش سند، تحقیق).
-- **برنامه (plan):** یک نقشه با «معیارهای موفقیت» می‌سازد که وارسی بعداً آن‌ها را چک می‌کند.
-- **اجرا (execute):** گام‌ها را به مدل‌ها می‌سپارد و هر گام را به‌عنوان یک «ردپا» ثبت می‌کند.
-- **وارسی (verify):** اسکریپت‌های سنجش را اجرا می‌کند. نکتهٔ مهم: اگر هیچ شاهدی تولید نشود، نتیجه «پوچ» (vacuous) علامت می‌خورد، نه «قبول» — یعنی سیستم به «تئاتر تست» باج نمی‌دهد.
-- **بازتاب (reflect):** از ردپاها درس می‌گیرد و سیاست مسیریابی را بازمحاسبه می‌کند.
-- **بهبود/ارزیابی/ترفیع:** حلقهٔ آفلاین تکامل؛ نسخه‌های بهتر پیشنهاد، سنجش و در صورت برتری «ترفیع» می‌شوند.
-
-**نمرهٔ کیفیت درون هر اجرا:** بعد از اجرا، یک روبریک ۸ موردی به کار نمره می‌دهد و آن نمره روی همهٔ ردپاهای آن اجرا به‌عنوان «پاداش» ثبت می‌شود. یعنی سیستم به‌جای «قبول/رد» ساده، **کیفیت** را یاد می‌گیرد.
-
-### خطوط مدل (lanes) و مسیریاب
-
-هفت خانوادهٔ مدل در دسترس است (opus، sonnet، codex، deepseek، glm، kimi، minimax). هر «نقش» (برنامه‌ریز، پیاده‌ساز، داور، وارسی‌کننده…) به یک مدل نگاشت می‌شود. برای پنل‌های چندنظره از خانواده‌های متفاوت استفاده می‌شود تا نظرها هم‌بستگی کاذب پیدا نکنند.
-
-### قلب یادگیری: مسیریابی به سبک GRPO
-
-این مهم‌ترین تکنیک mini-ork است. ایده ساده اما قدرتمند است: **هر مدل را با هم‌گروهی‌هایش روی «همان کار» مقایسه کن، نه به‌طور مطلق.**
-
-- **گروه** = مجموعهٔ ردپاهایی که روی کار یکسانی رقابت کرده‌اند؛ کلید گروه = (حوزهٔ هدف، نوع کار، نوع گام، ناحیهٔ کد).
-- **مزیت نسبی** = نمرهٔ هر مدل منهای میانگین گروه. اگر مدلی از هم‌گروهی‌هایش بهتر عمل کند، «مزیت مثبت» می‌گیرد.
-- چند تعدیل مهم روی این عدد اعمال می‌شود تا پایدار بماند:
-  - **وزن تازگی:** داده‌های جدیدتر مهم‌ترند (نیمه‌عمر ۱۴ روز).
-  - **انقباض (shrinkage):** گروه‌های کم‌نمونه کمتر اعتماد می‌گیرند (`n/(n+5)`).
-  - **میانگین‌گیری نمایی (EMA):** سیاست جدید ترکیبی از دستهٔ تازه و سیاست قبلی است تا نوسان نکند.
-  - **جریمهٔ نقص:** اگر مدلی در ناحیه‌ای باگ زده، امتیازش با گذشت زمان محو می‌شود اما موقتاً جریمه می‌گیرد.
-
-سرانجام «مدلِ ترجیحی» برای هر کار انتخاب می‌شود و این انتخاب از **ناحیه ← حوزه ← کلی** آبشاری بالا می‌رود (اول خاص‌ترین سطح، بعد عمومی‌تر). نکته: هیچ softmax یا log-sigmoid در مسیر نیست؛ «انتخاب» صرفاً بیشینهٔ مزیت نسبی است.
-
-### پاداش: سه لایه روی هم
-
-۱. **پاداش نرمال‌شده (`reward_g`):** جهت‌دار و بی‌مقیاس؛ `(مقدار − لنگر)/|لنگر|`. اگر لنگر صفر باشد، «بدون سیگنال» علامت می‌خورد (نه صفر) — یعنی نبود مبنا با شکست اشتباه گرفته نمی‌شود.
-۲. **شکل‌دهی مبتنی‌بر وارسی:** اول پاداش فرایندی، بعد لنگر وضعیت (۰٫۸۵ موفق / ۰٫۱۵ ناموفق)، بعد رأی داور به‌عنوان تفاوت جزئی (±۰٫۱). فاصلهٔ ۰٫۵ تضمین می‌کند یک داور مغرض نتواند نتیجهٔ معلومِ خوب/بد را برعکس کند.
-۳. **مدل پاداش فرایندی (PRM):** جمع وزنی سیگنال‌ها (وضعیت ۰٫۴، ابزار ۰٫۲، فایل ۰٫۱، رأی ۰٫۱۵، زمان ۰٫۱، هزینه ۰٫۰۵). یک **سقف فعالیت (۰٫۱۵)** جلوی «شلوغ‌کاری بی‌حاصل» را می‌گیرد تا کار پرسروصدای شکست‌خورده از موفقیت ساده جلو نزند (محافظ گودهارت).
-
-### `decide()` — مغز مشترک و بدون‌حالت
-
-یک تابع تصمیم واحد که همهٔ مصرف‌کننده‌ها آن را صدا می‌زنند و هیچ حالتی نگه نمی‌دارد. خروجی‌اش می‌گوید: کدام مدل، آیا ائتلاف داورها متنوع است، برآورد پاداش چقدر است، و راهنمای بازگشت (recursion). یک نکتهٔ مهم: **اکتشاف ε-حریصانه** — با احتمال ۱۰٪ عمداً یک مدل دیگر امتحان می‌شود تا سیستم در یک انتخاب محلی گیر نکند؛ اما فقط وقتی که قبلاً یک مسیر «یادگرفته‌شده» وجود داشته باشد (در شروع سرد، ریسک نمی‌کند).
-
-«پارتیشن‌بندی حوزهٔ هدف» یعنی یک سیاست مشترک می‌تواند به مصرف‌کننده‌های متفاوت (تیم مهندسی، تولید کتاب، تحقیق…) خدمت بدهد بدون اینکه معیارهایشان با هم قاطی شود.
-
-### بازتاب: «گرادیان»‌های متنی
-
-اینجا «گرادیان» یک عدد نیست، بلکه یک **سیگنال بهبودِ متنی** است (به سبک TextGrad): «این گام از این جهت ضعیف بود، این تغییر را بده». این گرادیان‌ها استخراج، حذف‌تکرار، و در صورت تکرار در چند نوع کار، به یک الگوی «بین‌کاری» ترفیع می‌شوند.
-
-### دروازه‌ها (gates)
-
-مجموعه‌ای از نگهبان‌ها که جلوی خودفریبی سیستم را می‌گیرند:
-- **دروازهٔ ترفیع:** یک نسخه فقط وقتی ترفیع می‌گیرد که در سنجش، هم امتیاز کافی بگیرد و هم سودمندی‌اش منفی نباشد.
-- **دروازهٔ ائتلاف:** اگر نظر داورها بیش از حد هم‌بسته باشد یا از یک خانواده باشند، پنل باطل می‌شود (تنوع اجباری).
-- **راستی‌آزمای ارجاع:** هر ارجاع `فایل:خط` واقعاً باید وجود داشته باشد و در محدوده باشد — جلوی «استناد جعلی» را می‌گیرد.
-- **قطع‌کن مدار (circuit breaker):** اگر خروجی تکراری شد، رأی گیر کرد، یا هزینه سوخت بدون نوشتن فایل، اجرا متوقف می‌شود.
-
----
-
-## بخش ب — TraceOtter: تبدیل ردپا به مدل محلی
-
-ایدهٔ اصلی: **از روی کارهایی که واقعاً انجام شده، به یک مدل کوچک محلی یاد بده چه‌کار کند** تا در آینده بخش زیادی از کارها را ارزان و محلی انجام دهیم.
-
-### خط لولهٔ تقطیر
-
-لاگ‌های خام گفتگو (Claude/Codex/mini-ork) خوانده می‌شوند ← هر جلسه به یک «اپیزود» ساختارمند تبدیل می‌شود ← «مهارت»‌های تکرارشونده استخراج می‌شوند ← دروازهٔ کیفیت فیلتر می‌کند ← یک مجموعه‌دادهٔ آموزشی خروجی می‌گیریم.
-
-### برچسب «مسیر» (route) — هدف اصلی مدل
-
-مدل باید یاد بگیرد که برای هر کار **چه نوع اقدامی** درست است؛ پنج برچسب: «سند/بازبینی»، «ویرایش مستقیم»، «worktree»، «ارکستراسیون»، «درخواست زمینهٔ بیشتر». نکتهٔ ظریف: برچسب درست از روی **کارهای واقعاً انجام‌شده** (دستورات شل و نوع گام‌ها) استخراج می‌شود، نه از روی کلمات ورودی — وگرنه سنجش دورانی و بی‌معنا می‌شد.
-
-### مهارت‌ها — حافظهٔ رویه‌ای (الهام‌گرفته از MemP)
-
-یک «مهارت» یک الگوی رویه‌ای تکرارشونده است (مثلاً «جست‌وجو سپس ویرایش» یا «تست بعد از پیاده‌سازی»). معیار اعتبار، **تعداد اپیزودهای متمایز** است که آن الگو در آن‌ها دیده شده، نه تعداد کل تکرار. هر مهارت یک شرطِ فعال‌شدن، یک رویه، یک قرارداد وارسی، منبع، و یک عدد اطمینان دارد.
-
-### پاک‌سازی و کیفیت
-
-- **حذف اسرار:** کلیدها، توکن‌ها و مسیرهای شخصی **در لحظهٔ پارس** پاک می‌شوند تا هرگز وارد دادهٔ آموزشی نشوند.
-- **دروازهٔ کیفیت:** اپیزودهای خالی، پرنویز، شکست‌خورده، تکراری یا بیش‌ازحد بلند حذف می‌شوند.
-- **پالایش شواهدمحور (A/B):** به‌جای حذف کورکورانه، با/بدون گروه مشکوک ارزیابی می‌شود و فقط وقتی حذف توصیه می‌شود که معیار روی دادهٔ کنارگذاشته بدتر نشود.
-
-### آموزش LoRA و انضباط «تک‌دوره»
-
-مدل پایه یک مدل کوچک (Qwen3-4B) است و با روش LoRA فقط بخشی از وزن‌ها تنظیم می‌شود. یک درس مهم اینجا هست: **آموزش چنددوره‌ای روی دادهٔ تقطیرشده باعث «فراموشی فاجعه‌بار» می‌شود** (افت توانایی، تکرار، حلقهٔ فکری). برای همین فقط **یک دوره** آموزش می‌دهیم؛ همین برای انتقال سبک و مهارت کافی است و توانایی پایه حفظ می‌شود.
-
-### دروازهٔ واقعی: دقت مسیر روی دادهٔ کنارگذاشته
-
-معیار قبول/رد **دقت مسیر روی دادهٔ دیده‌نشده** است، نه کاهش خطای آموزش. چون خطای آموزش می‌تواند پایین بیاید در حالی‌که رفتار مدل بدتر شود. در ارزیابی واقعی، هر نمونه دو بار اجرا می‌شود: یک‌بار با مدل پایه، یک‌بار با آداپتور — و می‌سنجیم که آیا مدلِ تنظیم‌شده واقعاً بهتر شده. عدد واقعی: مدل پایه ۰٪ (اصلاً قالب مسیر را تولید نمی‌کند) و مدل تنظیم‌شده حدود **۷۲٪** روی داده‌ای که در آموزش ندیده — همان «۷۲٫۴٪» که نقل می‌شود.
-
-### طراحی یادگیری پیوسته (JitRL)
-
-نقشهٔ آینده: به‌جای آموزش مکرر و گران، یک «حافظهٔ سه‌تایی» از (حالت، اقدام، پاداش) نگه داریم و با یک **به‌روزرسانی بستهٔ لاجیت** روی مدلِ **منجمد** رفتار را اصلاح کنیم — بدون تغییر وزن‌ها. حلقهٔ سریع هر جلسه (بدون گرادیان، لحظه‌ای)، حلقهٔ کند هفتگی (یک به‌روزرسانی وزن دروازه‌دار با بافر بازپخش تا فراموشی رخ ندهد). نتیجه: حدود ۳۰ برابر ارزان‌تر و بدون فراموشی.
-
----
-
-## بخش ج — ContextNest: حافظه به‌شکل «میدان عصبی»
-
-ContextNest گفتگوها را به یک **میدان از خاطره‌ها** تبدیل می‌کند که خاطره‌های مشابه دور هم جمع می‌شوند. (نکتهٔ مهندسی: خاطره‌ها در حافظهٔ درون‌برنامه‌ای + یک WAL نگه‌داری می‌شوند، نه در یک پایگاه‌دادهٔ SQL؛ و بردارها با مدل Qwen3 ساخته می‌شوند.)
-
-### حوضچه‌ها (Basins) — چاله‌های جاذبه
-
-یک «حوضچه» یک ناحیه در فضای بردارهاست با **مرکز، شعاع (بُرد جاذبه)، و عمق (شدت جاذبه)**. خاطره‌های شبیه‌به‌هم مثل توپ‌هایی که در یک گودال می‌غلتند، به یک حوضچه جذب می‌شوند. این یک مدل واقعی «چشم‌انداز انرژی» است، نه صرفاً خوشه‌بندی ساده:
-- **نیروی جاذبه** بیرون از دو برابر شعاع صفر است و نزدیک مرکز قوی‌تر می‌شود.
-- **شکل‌گیری:** هر خاطرهٔ تازه اگر به نزدیک‌ترین حوضچه به‌قدر کافی نزدیک باشد (فاصلهٔ ≤ ۰٫۴) به آن **می‌چسبد**، وگرنه یک حوضچهٔ **جدید** می‌سازد. (این دقیقاً باگی را حل کرد که قبلاً هر خاطره یک حوضچهٔ جدا می‌ساخت.)
-- **تکامل و شکل‌دهی:** حوضچه‌ها با زمان جابه‌جا می‌شوند، رشد می‌کنند، عمقشان تغییر می‌کند، و «سلامت»شان (بر اساس انسجام، پوشش، فعالیت، پایداری) سنجیده می‌شود؛ حوضچه‌های ناسالم هرس می‌شوند و حوضچه‌های نزدیک با هم **ادغام** می‌شوند.
-
-### تکه‌ها (Fragments) — کوانتوم حافظه
-
-هر خاطره یک «تکه» است. یک نکتهٔ ظریف مهندسی: در تکهٔ کانونی، فیلد `content` در واقع **بردار جاسازی است، نه متن**؛ متن و فراداده در نقشه‌های جانبی نگه‌داری می‌شوند. هر تکه به یک حوضچه و به تکه‌های مرتبط دیگر (اتصال‌ها) وصل است.
-
-### میدان: فراموشی، برجستگی، فعال‌سازی
-
-آنچه در بازیابی واقعاً استفاده می‌شود یک زنجیرهٔ **تضعیف ضربی** است:
-- **فراموشی (decay):** خاطره‌ها با زمان کم‌رنگ می‌شوند (نیمه‌عمر ۶۰ روز)، اما انواع بادوام (تصمیم، وارسی، ویژگی، درس) دو برابر کندتر و انواع فرّار (وضعیت، متن خوانده‌شده) دو برابر سریع‌تر.
-- **تقویت با دسترسی:** هر بار که خاطره‌ای بازیابی می‌شود، «آخرین دسترسی»‌اش تازه می‌شود — یک حلقهٔ تقویت تازگی.
-- **برجستگی از هم‌رخدادی:** خاطره‌هایی که با هم بازیابی می‌شوند، یک یال اتصال می‌گیرند (رزونانس واقعی میدان).
-
-> نکتهٔ صادقانه: یک لایهٔ نظری زیبا از «میدان عصبی و رزونانس» در کد هست که **در مسیر واقعی درخواست‌ها فعال نیست**؛ منطق واقعی بازیابی به‌شکل درون‌خطی پیاده شده. حوضچه‌ها واقعی و فعال‌اند؛ آن نظریهٔ پیچیده‌تر فعلاً داربست است.
-
-### استخراج‌گر و انواع خاطره
-
-استخراج‌گر، هم متن گفتگو و هم بلوک‌های ساختارمند `<z-insight>` را که دستیار تولید می‌کند می‌خواند و آن‌ها را به انواع خاطرهٔ نوع‌دار تبدیل می‌کند؛ از جمله: عنوان جلسه، فاز هدف، دستاورد، درس، تصمیم، مانع، ویژگی تحویل‌شده، فایل‌های لمس‌شده، متن خوانده‌شده، وارسی، شکست، فرضیه، ریسک، و «نامزد حافظه». هر نوع یک «اهمیت» پایه دارد (مثلاً دستور راهنما ۰٫۹۵، وضعیت ۰٫۵).
-
-### راستی‌آزمایی منبع — ضد خاطرهٔ توهمی
-
-این یکی از مهم‌ترین و متمایزترین تکنیک‌هاست: هر ادعای خوداظهاری با **شواهد واقعی ابزار** سنجیده می‌شود.
-- **وارسی:** ادعای «تست پاس شد» با خروجی واقعی دستور Bash مقایسه می‌شود و «رسید» شمارش (`N passed / M failed`) استخراج می‌گردد. اگر ادعا بگوید پاس ولی رسید شکست نشان دهد → برچسب **«رد شده» (contradicted)** و رسید بر متن غالب است.
-- **ویژگی:** فایل‌های ادعاشدهٔ یک ویژگی با فایل‌هایی که واقعاً ویرایش شده مقایسه می‌شود؛ اگر هیچ‌کدام ویرایش نشده باشد → «غایب» (تحویل جعلی).
-
-این برچسب‌ها بعداً در بازیابی به‌عنوان ضریب **اعتماد** ضرب می‌شوند (دیده‌شده ۱٫۰، مدعی ۰٫۴، رد‌شده ۰٫۲۵). یعنی خاطره‌های اثبات‌نشده خودبه‌خود کم‌وزن می‌شوند.
-
-### فرمول امتیاز بازیابی
-
-هر خاطره در پاسخ به یک پرس‌وجو این‌طور امتیاز می‌گیرد:
-
-`شباهت نهایی = کسینوس × فراموشی × وزنِ‌نوع × چگالی‌محتوا × اعتماد`
-
-سپس با «هم‌حوضچه‌ای‌ها» و «هم‌اتصال‌ها» گسترش می‌یابد (فعال‌سازی انتشاری) و در نهایت یک **کپسول متن** مرتب و آمادهٔ چسباندن در پرامپت اجرای بعدی ساخته می‌شود.
-
-### حلقهٔ بازخورد به mini-ork
-
-- **مغز ← حافظه:** برنامه‌ریز و کارگرها قبل از شروع، کپسول متن مرتبط را از ContextNest می‌گیرند.
-- **حافظه ← مغز:** بعد از پایان کار، mini-ork می‌گوید کدام خاطره‌ها را مصرف کرد و نتیجه چه شد؛ ContextNest سیگنال اعتماد آن خاطره‌ها را کمی بالا/پایین می‌برد (سقف‌دار، تا یک کارگر پرنویز نتواند یک حوضچه را قفل کند).
-
----
-
-## بخش د — سیستم چطور در کل یاد می‌گیرد
-
-۱. **کار اجرا می‌شود:** mini-ork کار را دسته‌بندی می‌کند، برای هر گام مدل انتخاب می‌کند، و هر قدم را ثبت می‌کند.
-۲. **پاداش ثبت می‌شود:** روبریک به اجرا نمره می‌دهد و PRM به هر گام؛ وارسی موفق/ناموفق/پوچ را ثبت می‌کند.
-۳. **چرخ‌طیار ۱ (مسیریابی):** بازتاب، مزیت نسبی هر مدل را در گروه هم‌جنس بازمحاسبه می‌کند و انتخاب به سمت مدل برنده جابه‌جا می‌شود.
-۴. **چرخ‌طیار ۲ (وزن‌ها):** TraceOtter همان ردپاها را به داده تبدیل و مدل محلی را آموزش می‌دهد و با دقت مسیرِ دیده‌نشده دروازه‌بندی می‌کند.
-۵. **چرخ‌طیار ۳ (حافظه):** ContextNest خاطره می‌سازد، ادعاها را راستی‌آزمایی می‌کند، در حوضچه‌ها متراکم می‌کند و کپسول متن را به اجرای بعدی می‌دهد.
-۶. **تکرار:** هر اجرا باعث می‌شود اجرای بعدی بهتر مسیریابی کند، ارزان‌تر تمام شود، و با حافظهٔ مستندتر شروع شود — همان «منحنی مرکب» (compounding).

-
-## بخش ه — نکات صادقانه (اغراق نکنیم)
-
-- **mini-ork:** بهینه‌ساز پرامپت (GEPA) فقط **پیشنهاد** می‌دهد و خودکار اعمال نمی‌شود؛ تنها راهبرد اکتشاف، ε-حریصانه است (نه Thompson/Beta/UCB).
-- **TraceOtter:** بین کد فعلی و آرتیفکت‌های اجراشده «رانش» هست (مدل پایه در فایل‌های مختلف Qwen3-4B / Qwen2.5-Coder-1.5B / Qwen2.5-0.5B دیده می‌شود؛ فایل آموزش می‌گوید ۳ دوره ولی مربی محلی ۱ دوره اعمال می‌کند). عدد «۰٫۷ دلار در هر چرخه» **در کد وجود ندارد** و یک برآورد بیرونی است.
-- **ContextNest:** لایهٔ زیبای «میدان عصبی/رزونانس» عمدتاً **در مسیر واقعی فعال نیست**؛ حافظه در حافظهٔ درون‌برنامه‌ای + WAL است نه SQL/Qdrant؛ بردارها Qwen3 (DeepInfra) هستند نه Gemini.
-- **کلی:** اعداد اقتصادی چشمگیر (۸۴٪ صرفه‌جویی توکن، برابری کیفیت) مدل‌سازی/دیده‌نشده‌اند، نه اثبات‌شده روی یک مشتری واقعی.

-# Techniques Compendium — mini-ork · TraceOtter · ContextNest
-
-*A single authoritative reference for every learning, orchestration, memory, and training technique across the three subsystems that make up the co-evolving dev substrate. Compiled 2026-07-09 from a line-by-line read of all three repos; claims are tagged `file:line` so they can be re-verified. Where the running artifacts disagree with the current source, both are noted — this doc does not paper over drift.*
-
-**The three systems and how they connect**
-
-- **mini-ork** — the orchestrator and the *policy brain*. Runs the task loop, routes each node to a model lane, records every step as a trace, and learns which lane wins per task via a GRPO-style relative-advantage update.
-- **TraceOtter** — the *weight arm*. Distils mini-ork/Claude/Codex execution traces into an SFT dataset and LoRA-trains a small local model, gated on held-out route accuracy.
-- **ContextNest** — the *memory substrate*. Turns session transcripts into a neural-field of attractor basins and fragments, grades every claim against real tool events, and feeds context back into mini-ork's planning while taking outcome feedback in return.
-
-The loop: mini-ork runs → traces land → ContextNest extracts + grades memory and TraceOtter distils + trains → both feed back into mini-ork's next routing/planning decision. Three flywheels (usage routing, local weights, memory) turning on the same trace stream.

-## Part A — mini-ork: orchestration + GRPO learning
-
-### A1. The universal loop
-
-Stages recognised by the dispatcher (`bin/mini-ork:15`): `classify → plan → execute → verify → reflect → improve → eval → promote`. The `run` path walks classify→plan→execute→(rubric)→verify→reflect inline (`bin/mini-ork:35`, `:455-525`); improve/eval/promote are the offline evolution sub-loop.
-
-| Stage | Entry | Mechanism |
-|---|---|---|
-| classify | `bin/mini-ork-classify` | Rank-by-hit-count keyword/regex scan of `config/task_classes/*.yaml` + `recipes/*/task_class.yaml` (`:162-253`). Word-boundary literals; regex hit +2; class-alias +3. `--task-class` forces override. Kickoff DoS cap `MO_MAX_KICKOFF_BYTES=1048576`. Writes `task_runs` status `classified`. |
-| plan | `bin/mini-ork-plan` | Emits `plan.json` with `artifact_contract.success_verifiers[]` + `verifier_contract.checks[]`. |
-| execute | `mini_ork/cli/execute.py` | Dispatches workflow nodes; hosts the GRPO write-half (`mo_learning_write_grpo_advantages`, `:432+`) and the lane-routing switch (`_mo_policy_route_lane`, `:1971`). |
-| verify | `bin/mini-ork-verify` | Runs `success_verifiers[]` then `gate_run_all` (`:305`). Empty-evidence exit-0 = `[fail] vacuous` (`:271-278`); zero verifiers run = verdict `vacuous`, not `pass` (`:317-323`). |
-| reflect | `mini_ork/cli/reflect.py` | Delegates to `reflection_run`, then pattern_miner, cross_epic_gradient, bug_report_sweep, rho_aggregate, lane_router_recompute, optional GEPA. |
-| improve | `bin/mini-ork-improve` | Reads per-task_class perf from `execution_traces`, calls `group_propose`, persists `workflow_candidates`. |
-| eval | `bin/mini-ork-eval` | Benchmarks a candidate, computes `utility_delta` vs baseline, transitions candidate→shadow. |
-| promote | `bin/mini-ork-promote` | `promotion_evaluate`; on pass registers a version + status `promoted`; on fail `quarantined` (permanent block). |
-
-**Online reward inside `run`:** between execute and verify, an 8-item rubric pre-screen (`mo_rubric_run_score`) runs and `mo_grade_run_reward` stamps the 0–8 score as `reward_g` on every trace of the run (`bin/mini-ork:468-489`), so GRPO learns run *quality*, not just pass/fail. Auto-reflect fires after verify (`MO_AUTO_REFLECT=1`, batch 25).
-
-### A2. Model lanes and the router
-
-Seven model families via `lib/providers/cl_{opus,sonnet,codex,deepseek,glm,kimi,minimax}.sh`. Lane→role mapping in `config/agents.yaml`: `planner:sonnet, implementer:sonnet, reviewer:opus, verifier:sonnet, reflector:sonnet, decomposer:deepseek, brain:opus`. Heterogeneous-family lens lanes (`glm_lens, kimi_lens, codex_lens, opus_lens, minimax_lens`) each a distinct family to lower panel pairwise correlation (Rajan 2025). Budgets: per_epic $5, per_run $0.50, daily $50.
-
-**Routing policy switch** `_mo_policy_route_lane` (`mini_ork/cli/execute.py`), env `MO_ROUTING_POLICY` default `learning_governed`. Policies: `workflow_default`, `frontier_only`, `cheap_only`, `static_hybrid`, `learning_governed`, `trace_governed` (escalate to frontier when `FAIL_COUNT>0`). Dry-run preserves recipe lanes.
-
-`learning_governed` → `_mo_learning_governed_lane` (`:344-394`): resolves `task_class` + `objective_domain` (default `code-delivery`), delegates to `decide()`, reads `.route`. Epsilon exploration deliberately lives on the brain side, not here.
-
-### A3. The GRPO relative-advantage router
-
-`mini_ork/lane_router.py` (Python port of `lib/lane_router.sh`). The policy is *argmax relative advantage per group*:
-
-- **Advantage**: `relative_advantage[i] = score[i] − mean(group)`, `score = reward_g` (NULL skipped) (`lane_router.py:97,164`). The bash write-half uses **z-score** `(score − mean)/std` instead (`mini_ork/cli/execute.py`).
-- **Group key** = `(objective_domain, task_class, node_type, code_region)` (`:132`); groups of size <2 skipped.
-- **Recency weight** `w = exp(−ln2·age_days/HALFLIFE)`, `MO_LEARNING_HALFLIFE_DAYS=14` (`:127-129`).
-- **Weighted group mean** → per-lane `lane_adv = lane_mean − wmean + lane_bonus` (`:163-164`).
-- **Shrinkage** `n/(n+K)`, `K=MO_LEARNING_SHRINKAGE_K=5` (`:166`).
-- **EMA blend** `new = α·batch + (1−α)·prior`, `α=MO_LEARNING_DECAY_ALPHA=0.30` (`:217-232`).
-- **Cost tie-break** on flat groups: bonus `0.1 − 0.2·(cost−lo)/(hi−lo)`, gated `MO_LEARNING_TIEBREAK=1` (`:150-155`).
-- **Decayed defect penalty** on the region slice: `pen · 0.5^(age/hlf)` from `defect_attributions` (`:185-215`).
-
-Persists to `agent_performance_memory` (global), `lane_domain_advantage`, `lane_region_advantage`. `preferred_lane()` reads the highest-advantage lane with sample floor `MO_LEARNING_MIN_SAMPLES=3`, cascading **region → domain → global** (`:286-330`). No log-sigmoid/softmax in the routing path — "margin" here means argmax-of-relative-advantage only.
-
-**What a "group" is:** the set of traces competing on identical work `(objective_domain, task_class, node_type, code_region)`. A lane is rewarded for *beating its peers on the same task*, not for absolute score — the core GRPO idea.
-
-### A4. Reward — three stacked signals
-
-1. **`compute_reward_g`** (`mini_ork/trace_store.py:28-40`): `reward_g = sign·(value−anchor)/|anchor|`; `sign=+1` if higher-is-better else `−1`; **`anchor==0 → None`** (unanchored = no signal). Scale-free, direction-normalised gain the router reads.
-2. **Verifiable-first shaping** (`mini_ork/cli/execute.py`): precedence `process_reward` → status anchor (0.85 success / 0.15 fail) → reviewer-verdict tie-break `±0.10`, zeroed on same-family lanes. The 0.5 anchor gap means an adversarial reviewer can't flip a known-good/bad trace.
-3. **Process Reward Model (PRM)** (`lib/process_reward.sh` + `mini_ork/learning/process_reward.py:55-124`): additive weights `W_STATUS=0.40, W_TOOL=0.20, W_FILE=0.10, W_VERDICT=0.15, W_DURATION=0.10, W_COST=0.05`. **Goodhart guard** `ACTIVITY_CAP=0.15` clamps tool+file so noisy failed work can't outscore bare success. Bash/Python parity enforced to 1e-6 (`test_process_reward_parity.py`).
-
-**`grade_run_reward`** (`trace_store.py:195-223`): rubric `score/8` normalised against neutral **anchor 0.5** → `reward_g=(val−0.5)/0.5 ∈ [−1,+1]`, `reward_source='rubric@v1'`.
-
-### A5. decide() — the stateless shared-brain RLM
-
-`lib/decision_service.sh` `decide <node_type> <task_class> <objective_domain> [segment]` (`:80`) → JSON `{route, coalition_ok, reward_estimate, recursion_hint, sample_size, segment, code_region}`. No per-request state, no side effects, no LLM dispatch. Composed reads:
-
-- **route** — `lane_router_preferred_lane` (GRPO floor ≥3); cold-start falls back to the `agents.yaml` lane for the node_type — **never invents a lane**.
-- **ε-greedy exploration** (`:108-178`): prob `MO_LEARNING_EPSILON=0.10` swap to a deterministic agents.yaml lane (`SEED` reproducible; else `SystemRandom`); fires only when a learned route already exists.
-- **coalition_ok** — family-diversity check over the slice via `LANE_TO_FAMILY`; ok when sample<2 or every lens is a distinct family.
-- **reward_estimate** — mean normalised `reward_g` over the slice, falling back to `process_reward`.
-- **recursion_hint** — `max_depth=2, max_children=4, max_descendants=16, max_parallel=4`.
-
-**objective_domain partitioning** is the outermost GRPO slice key (`code-delivery | review | research | ops | book-gen | …`). One shared learned policy serves heterogeneous consumers without cross-contaminating their metric shapes — the motivation stated in migration `0042`'s header.
-
-### A6. trace_store — the ledger everything learns from
-
-`execution_traces` (`db/migrations/0010`): `trace_id` PK, `run_id`, `task_class`, `prompt_version_hash`, `context_bundle_hash`, `tool_calls`/`files_read`/`files_written` (JSON), `reviewer_verdict`, `cost_usd`, `duration_ms`, `status` (incl. `vacuous`). Reward columns: `process_reward` (0031); the ten objective-aware columns from **0042** (`objective_domain, segment, reward_primary_metric, reward_direction, reward_value, reward_anchor, reward_g, reward_vector_json, reward_source, validity`); `code_region` (0044). Write path `trace_write` (`trace_store.py:67-137`) UPSERTs on `trace_id`, computes `reward_g` unless explicit, normalises legacy double-encoded `verifier_output`.
-
-### A7. Reflection — "gradients" (TextGrad-style)
-
-A **gradient** is a *textual* improvement signal: `{gradient_id, target, signal, suggested_change, evidence(trace_id), confidence, task_class}` in `gradient_records` (`mini_ork/learning/gradient_extractor.py`, migration 0038). `target` ∈ `workflow.node.<n> | agent.<role>.prompt | workflow.edge.<n> | verifier.<n> | workflow.recipe.<n>`.
-
-`reflection_run` (`mini_ork/learning/reflection_pipeline.py`) runs 7 stages: **extract_gradients** (LLM 0–5 per trace, model `codex`, brace-balanced JSON recovery) → **deduplicate** (exact then `difflib` ≥0.55) → **link_failures** → **detect_stale** (`>14d`) → **summarize_patterns** (`pattern_records`) → **suggest_promotions** (`frequency ≥ 3`) → **persist** (idempotent upsert to `emergent_patterns`). **cross_epic_gradient** promotes a target recurring across ≥2 task_classes at conf ≥0.7 to `__cross_class__` with id `gr-cx-<sha256(target)[:12]>`.
-
-### A8. Gates
-
-| Gate | File | Enforces |
-|---|---|---|
-| gate_registry | `lib/gate_registry.sh` | 8 gate types; safety gates unremovable; `gate_run_all` from verify. |
-| promotion_gate | `lib/promotion_gate.sh` | Reads `benchmark_results`+baseline → `promoted/rejected/quarantined(utility_delta≤0)/pending_human`. Synthesis-class conjunction gate needs **all 3**: panel ≥`MO_PROMOTE_SCORE_THRESHOLD=80`, CW-POR ≤0.3, ≥1 structural signal. Anti-Ouroboros (Zenil 2026). |
-| coalition_gate | `lib/coalition_gate.sh` | Abort when pairwise ρ ≥ `MO_RHO_THRESHOLD=0.25` (Rajan 2025) or family_count < lens_count (Bertalanič 2026). |
-| citation_verifier_mechanical | `lib/citation_verifier_mechanical.sh` | Resolves `path:line` citations vs `MINI_ORK_ROOT`; `CITATION_UNDERCOVERED` below `MO_CITATION_COVERAGE_FLOOR=0.8`. Anti-wireheading: proves the validator read the file. |
-| adaptive_stability | `lib/adaptive_stability.sh` | Round-over-round verdict drift; HALT below `0.10`, never before 2 rounds, always by 5 (Hu 2025). |
-| circuit_breaker | `lib/circuit_breaker.sh` | Behavioural liveness: artifact-hash invariant + verdict-stuck + cost-burn-no-write, 2-of-3 majority; CLOSED/OPEN/HALF_OPEN, cooldown 1800s. |
-
-Also present: `krippendorff_alpha_gate`, `refute_or_promote_gate`, `honest_ci_gate`, `cw_por` (authority-capture). All fail-open `indeterminate`.
-
-### A9. GEPA optimizer (prompt evolution)
-
-`mini_ork/optimize/gepa.py` — reflective **prompt** optimiser (not weights). `optimize(seed, adapter, minibatch=8, budget=4)` maintains a `ParetoFront` over `(candidate, full_score)`; each iteration selects the best parent, `make_reflective_dataset` → `reflect_on_component` (LLM rewrites one component key), then a **strict-improvement minibatch gate** (`sum(new)>sum(parent)`) before paying a full eval — the "35× rollout savings." `miniork_adapter.py` sources offline `execution_traces` (`reward_value` signal), never fabricates (hash-miss → parent mean). **Wired suggest-only, only under `MO_OPTIMIZER=gepa`** — never auto-applies.
-
-### A10. Scoring-math inventory
-
-GRPO advantage (mean-sub / z-score) · shrinkage `n/(n+5)` · EMA α=0.30 · recency half-life 14d · decayed defect penalty · ε-greedy (the *only* bandit — **no Thompson/Beta/UCB implemented**) · Krippendorff's α `1−D_o/D_e` (escalate below 0.4) · pairwise ρ ceiling 0.25 · win-rate `wins/(wins+losses)` (`prompt_win_rates`) · topology selection `performance·√novelty` · UtilityScore `U = 0.45·success + 0.20·verifier + 0.15·quality − 0.10·cost − 0.05·latency − 0.05·risk`.

-
-## Part B — TraceOtter: trajectory distillation → local model
-
-### B1. The pipeline
-
-`run_pipeline` (`traceotter/pipeline.py:51`): **ingest** (parse JSONL → typed `Episode`, write `episodes.jsonl` + `manifest.json`) → **consolidate_skills** → **run_quality** → **quality-gate join** (keep only `episodeId`s surviving `filtered_episodes.jsonl`, `:59-61`) → **export_llamafactory** → **report.json**. Discovery globs `**/*.jsonl`, `COMPLETION_REPORT.md`, `*summary*.json`, `*verdict*.json`. `distill` is a pure alias.
-
-### B2. Data model & the (input, output) pair
-
-Dataclasses (`models.py`): `Step` (index/actor/action_kind/summary/command/files/…), `Outcome` (status + **real measured** `input_tokens/output_tokens/cost_usd/tool_calls/tool_errors/files_written/files_read`), `Labels` (should_imitate/process_score/cost_efficiency_score/grounding_ratio), `Episode`, `Skill`.
-
-Parsing (`adapters.py`): Claude uses Anthropic `tool_use` blocks as authoritative for step kind (killed "phantom edit" steps, `:420`); Codex correlates a verify `exec_command` `call_id` with its exit code. Honest outcome (`_finish_episode:467`): cost from `message.usage` priced at `_PRICE_PER_MTOK`; `tests_passed` parsed from real pytest/go/cargo signatures; `status` grounded (`failed`/`completed`/`partial`) NOT keyword-matched; `process_score = 0.5·(1−tool_error_rate) + 0.3·grounding_ratio + 0.2·(no unsafe failure)`.
-
-**Training pair** (`exporters.py`): **input** = `repo/cwd/user_goal/task_type/candidate_skills/observed_steps` (first 20); **output** = `route: <label>\nprocedure:\n…\nverification:\n…\noutcome_status: …`; fixed instruction *"choose the route, key procedure, and verification plan."*
-
-**The route label** — the model's primary decision target, 5 classes (`eval.py:14`): `docs_or_review, direct_edit, worktree, orchestration, ask_for_context`. Ground truth `_expected_route` derived from **executed actions** (shell commands + step kinds), not prompt keywords — the fix that made route accuracy a real (non-circular) task.
-
-### B3. Skills — MemP-inspired procedural memory
-
-`consolidate_skills(episodes, min_support=2)` (`skills.py:11`): **support = count of distinct episodes** (not raw occurrences); drops below min_support; `skill_id = "skill_"+sha256(title+source_ids)[:12]`. `_normalize` = whitespace-collapse dedup key. `_categorize`: `cmd:`→verification, transitions (`search-then-edit`…)→process_pattern, else general. `_confidence = 0.15 + min(0.4,0.1·support) + 0.2·process + 0.15·completion + 0.1·test − failure_penalty`, clamped [0.05,0.95]. `_status_for`: stable/supported/candidate. A skill is a support-counted, self-describing procedural pattern with trigger + procedure + verification contract + provenance + confidence.
-
-### B4. Redaction & quality
-
-**Redaction** (`redact.py`) applied *at parse time*: api_key/token/secret/bearer/`sk-`/`ghp_`/`hf_` patterns, keep key name replace value; second stricter `SECRET_RE` + `PRIVATE_PATH_RE` in quality (`/Users/`, `/home/`, `/Volumes/` redacted).
-
-**Quality gates** (`quality.py:run_quality`): per-episode warnings (empty_goal/secret/noisy_only/failed_trace/missing_verification/overlong>32k/private_path/adp_schema/duplicate); `EXCLUDED_TYPES` dropped, private_path+missing_verification warn-only. **Curation A/B** (`curation.py`): evidence-based — recommends `exclude` only when dropping flagged episodes doesn't worsen and improves ≥1 of routeAccuracy/verificationCoverage/rubricScore; refuses to empty the eval set. **SFT export filter** `_should_export_for_sft`: drops failed/crash; a completed trace is positive only with verification and no `tests_passed is False`/failure_modes.
-
-### B5. LoRA recipe & the single-epoch discipline
-
-Current exporter (`exporters.py:183-202`): base `Qwen/Qwen3-4B-Instruct-2507`, template `qwen3_nothink`, LoRA `lora_target: all`, batch 2×grad-accum 8, lr 2e-4, cutoff 8192, bf16. LoRA rank/alpha live in the local trainer (`scripts/local_lora_train.py:107-112`): `r=8, alpha=16, dropout=0.05`, targets `q/k/v/o/gate/up/down_proj`.
-
-**Single epoch** (`local_lora_train.py:77-81`): multi-epoch LoRA distillation on curated data causes catastrophic forgetting (regressions/repetition/thinking-loops); 1 epoch transfers style/skill with capability retention. Prompt tokens masked to −100 (response-only loss). *Note the emitted LF yaml still says 3 epochs — the single-epoch rule is enforced by the local trainer, not the LF config.*
-
-### B6. Eval — held-out route accuracy is the gate
-
-`run_eval(…, holdout_ratio)` (`eval.py:24`): **held-out temporal split** = last fraction by sorted `episode_id` (`:108-111`); "last 20%" = `0.2`. Metrics: routeAccuracy (predicted vs action-grounded `_expected_route`), verificationCoverage, failedTraceRejection, processScore, rubricScore, safetyWarnings. **Why gate on held-out eval not train loss:** the real go/no-go (`local_eval_route.py`) runs each held-out example twice — `disable_adapter()` (base) vs adapter — and checks the `route:` line vs gold; train loss can fall while behaviour regresses.
-
-**Real checkpoint** (`saves/rp-researcher-eval/eval_report.json`): `n=150`, base `Qwen3-4B`, base route-acc **0.0** (base emits a valid route 0% of the time), tuned **0.72**, lift 0.72. Per-route: worktree 0.773, orchestration 0.732, docs_or_review 0.697, ask_for_context 0.656. This is the "72.4%" quoted in the roadmap.
-
-### B7. RunPod autopilot & JitRL
-
-**RunPod driver** (`scripts/runpod_autopilot.py`): creates an on-demand pod, SSHes with an ephemeral key, uploads trainer + data, trains, pulls the adapter tarball, and **always terminates in `finally`**. Weekly local path (`weekly-distill.sh`) is "local, private, free," cron `0 3 * * 0`, keeps 8 snapshots. *The "~$0.70/cycle" figure is not in the codebase — it's consistent with a single-epoch LoRA on a self-terminating spot 4090 but is an external claim, not asserted in code.*
-
-**Continual JitRL** (design, `docs/roadmap/m9-continual-jit-learning.md`): keystone **JitRL (arXiv 2601.18510)** — memory bank of `<s,a,reward>`, estimate `Â(s,a)` from historical returns, apply a **closed-form additive logit update `z'(s,a)=z(s,a)+β·Â(s,a)`** to a *frozen* base (Thm 4.1/4.3), >30× cheaper, zero forgetting. Two-speed: **fast loop** every session (no gradient, logits nudged at inference), **slow loop** weekly/JIT (one gated GRPO/on-policy-distillation weight update with replay buffer, held-out-gated + best-so-far rollback). **SKILL-DISCO (2606.26669)** upgrades `skills.py` flat list → routine graph (nodes=skills, edges=transitions weighted by freq+success). Recommendation: ship routine-graph + JitRL memory on the *existing 72.4% checkpoint* with no new training run.
-
-### B8. Real artifact numbers
-
-`.mini-ork/traceotter/`: 1,082 files discovered → 1,082 episodes → **271 SFT examples** survive the export filter → **3 consolidated skills** (all conf 0.95, candidate): preserve dirty-tree/stage owned files (15 eps), run focused verification + record commands (50 eps — largest), use a task-specific worktree (19 eps).

-## Part C — ContextNest: neural-field memory substrate
-
-*Resolved repo: `/Volumes/docker-ssd/ps/ContextNest` → `/Volumes/docker-ssd/Migration/Development/ContextNest` (the Rust substrate, ~102k LoC). The `ps/ML/ContextNest` checkout is empty scaffolding.* Rust (axum). **No SQL DB and no Qdrant for memories** — in-memory sidecar maps behind `RwLock`, persisted by a JSON WAL. Embeddings are **not Gemini** — OpenAI-compatible (DeepInfra Qwen3 default) or local.
-
-### C1. Basins — attractor basins (energy landscape)
-
-A basin is a region of embedding space with a **center vector, radius (attraction range), depth (attraction strength)**, clustering similar fragments. `AttractorBasin` (`src/memory/attractors/attractor_basin.rs:29-57`): center/radius/depth/shape/dynamics/associated_fragments/health/stability_score/basin_type (`Primary|Secondary|Temporary|Meta|Hybrid`). Shapes: `Spherical|Ellipsoidal|Irregular|Adaptive`.
-
-**Math:** attraction force = modified gravitational potential, zero outside `radius·2`, else `depth·(1−distance/(radius·2))²` toward center (`:269-298`); energy well `−depth·(1−(distance/radius)²).exp()`; convergence = gradient-descent at step 0.1 until within 0.01.
-
-**Shaping / evolution** (`update_dynamics:323-350`): `BasinDynamics{velocity, expansion_rate, depth_change_rate, damping, resonance_frequency}` — each tick center moves by `velocity·dt`, radius grows, depth changes, velocity damps, `stability_score` = EMA of velocity + age factors. **Health** = `0.3·pattern_coherence + 0.2·fragment_coverage + 0.3·activity_level + 0.2·stability`; activity decays `exp(−idle_s/3600)`; <0.3 pruned.
-
-**Formation** (`process_memories` Step 1, `memory_attractor_manager.rs:295-334`): each fragment finds its nearest basin; if euclidean ≤ **0.4** (`CONTEXTNEST_BASIN_ATTACH_THRESHOLD`, ≈ cosine 0.92 on normalised 768-d) it **attaches**, else it **seeds a new Secondary basin**. This fixed a real "one-basin-per-fragment" degeneracy (`avg_mass==1.0`). Merging: two basins merge when `distance < merged_radius·threshold`; merged center = depth-weighted average, depths sum.
-
-### C2. Fragments — the memory quantum
-
-Canonical `MemoryFragment` (`src/memory/attractors/mod.rs:92-110`): `id`, **`content: Vec<f32>` (the embedding, NOT text — a load-bearing naming quirk)**, `importance`, `created_at`, `last_accessed`, `attractor_basin_id`, `connections: HashSet`, `confidence`. Text + metadata live in side maps, never on the fragment. Five distinct fragment shapes exist across storage/resonance/gap-fill/reconstruction (`fragment_bridge.rs:1-25`). Each ingested `MemoryRecord` → fragment via `stable_fragment_id(session, text, metadata)`; at consolidation the text is embedded and run through `process_memories`.
-
-### C3. The field — resonance / decay / activation
-
-**Live field (what retrieval actually uses)** is a multiplicative attenuation pipeline (C7). Dynamics: **decay** `exp(−ln2/half_life · age_days)`, half-life 60d prefers `last_accessed`, and every retrieve **bumps `last_accessed`** on hits (a recency-reinforcement loop); **salience** via `connection_log` co-occurrence edges (top-2000 capped); **spreading activation** via basin/connection expansion.
-
-**Canon "neural field" layer is mostly dormant.** `ResonanceActivator` (`resonance_activation.rs`) computes `combined = 0.5·cue + 0.3·context + 0.2·network` with real spreading activation — but grep shows it is **not called by the API/service layer**; `tools.rs` reimplements resonance inline. Treat `src/context/*` (field.rs, resonance_activation.rs, neural_field_enhanced.rs, attractor_dynamics.rs) as aspirational scaffolding, not the live path.
-
-### C4. The extractor & every memory kind
-
-`extract_memories(events, session_uuid, project_cwd)` (`src/ingest/claude_code/extractor.rs:231-631`) parses Claude Code JSONL + the `<z-insight>{json}</z-insight>` blocks assistants emit (malformed JSON silently skipped). Each `MemoryRecord = {kind, text, importance, session_id_cn, metadata}`. Every `MemoryKind` and its z-insight source:
-
-| Kind | Source | Importance |
-|---|---|---|
-| session_title | first `ai-title` | 0.85 |
-| initial_prompt_window | first 3 user turns | 0.45 (boilerplate → weight 0) |
-| goal_phase | clustered `goal` stream | 0.85 |
-| Accomplishment | `top_jobs[]` | 0.75 |
-| Learning | `facts[]` | 0.80 |
-| Todo | `tasks[]` (dedup→final status) | 0.65–0.80 |
-| user_action | `requires_user_action[]` | 0.80 |
-| Decision | `decision` (awaiting) | 0.85 |
-| Blocker | `blockers[]` | 0.80 |
-| State | `current_state` | 0.50 |
-| current_task | `current_task` | 0.55 |
-| Summary | `/clear` summaries | 0.95 |
-| files_touched | Edit/Write/MultiEdit `file_path` | 0.85 |
-| Feature | `delivered_features[]` | 0.90 |
-| Domain | top-level `domain`+`progress`+`topics[]` | 0.85 |
-| read_context | `read_context[]` | 0.65 |
-| Verification | `verification[]` | 0.75 (failed 0.85) |
-| evidence_ref | `evidence_refs[]` | 0.60 |
-| decision_made | `decisions[]` | 0.90 |
-| Failure | `failures[]` | 0.85 |
-| prompt_directive | `prompt_directives[]` | 0.95 |
-| Assumption | `assumptions[]` | 0.55 |
-| Artifact | `artifacts[]` | 0.70 |
-| memory_candidate | `memory_candidates[]` | 0.80 |
-| risk_flag | `risk_flags[]` | 0.90 |
-
-GoalPhase clustering is two-stage: token-overlap ≥0.50 (sync), embedding cosine ≥0.85 (async refine).
-
-### C5. Storage
-
-Sidecar "tables" in `ContextNestServices` (`src/services/mod.rs:69-202`): `fragment_texts` (source text), `fragment_metadata` (kind/ts/provenance/`_cn_content_density`/`_cn_confidence_signal`/`last_accessed`…), `session_index`, `connection_log` (co-occurrence edges), `embeddings_by_id`, `session_intent_embeddings`, `attractor_manager` (basins), `wal`, `consolidation_queue`. Write path (`sink.rs:314-367`) inserts text+metadata, enqueues consolidation, WAL-appends — **deliberately skips embedding + basin formation on the hot path**. Embeddings: Qwen3 via DeepInfra default; providers Ollama/HF/CustomHttp + local TF-IDF fallback. A **consolidation worker** (`consolidation.rs`) drains the queue off the hot path, embeds, runs `process_memories`, computes density, flips `_cn_consolidated` — without it the attractor pipeline is dormant.
-
-### C6. Retrieval & prompt-context assembly
-
-`POST /tools/retrieve` (`tools.rs:588-994`): resolve candidates → embed query → prefilter (metadata/exclude_kinds) → **hydrate + cosine score** → multiplicative re-weight (C7) → sort by similarity then importance → **basin-aware expansion** (top hit's basin members at `top_sim·0.7`) → **connection expansion** (1-hop graph neighbors at `top_sim·edge_weight·0.5`) → dedupe → top_k → bump `last_accessed` + update `connection_log`.
-
-**Prompt-context (the brain surfacing)** — `prompt_context.rs`, deterministic no-LLM: `/atoms` (flat filtered trajectory kinds), `/clusters` (collapse by `(kind, normalized_text)`, optional semantic union-find ≥0.85, ranked by **cross-session reach**), `/capsule` (Markdown digest ordered risks→decisions→failures→…→artifacts, pasteable into another agent's prompt). Session queries: by-file, by-feature, by-intent (per-session intent embedding), top-feature, trajectory.
-
-### C7. Scoring math
-
-Per-hit `similarity = base_cosine · decay · kind_weight · density · trust`:
-- **decay** `exp(−(ln2/60d)·age)` × kind durability (Durable ×2.0 for decision/verification/feature/learning; Volatile ×0.5 for state/read_context/files_touched).
-- **kind_weight** UserContent 1.0 / SystemState 0.5 / Boilerplate 0.0.
-- **density** normalised Shannon token entropy × alphabetic-word fraction (ID-strings ~0.2, prose ~0.7).
-- **trust** (provenance) observed 1.0 / partial 0.7 / claimed 0.4 / absent 0.4 / contradicted 0.25.
-
-Other constants: basin attach ≤0.4, goal clustering 0.50/0.85, connection creation cosine >0.7, semantic merge ≥0.85. Top-feature score `0.35·ln1p(freq)+0.40·file_overlap+0.15·recency+0.05·ln1p(defs)+0.05·has_refs`.
-
-### C8. Provenance grading — anti-hallucinated-memory
-
-The extractor grades self-reported claims against real tool events (Tool Receipts, arXiv 2603.10060). **Verification** (`extractor.rs:1140-1182`): pairs each `verification[]` claim to its Bash run, parses exact `N passed / M failed` receipts → tiers `observed` (receipt confirms) / `contradicted` (claim says pass, receipt shows failures — receipt overrides) / `partial` / `absent` (command cited, no receipt = fabricated) / `claimed` (no command). **Feature** grades `delivered_features[].files` vs real Edit/Write paths (`absent` = fabricated deliverable). **ReadContext** flags a cited repo path never read. These tiers become the `trust` multiplier at retrieve time.
-
-### C9. Feedback loop into mini-ork (EvoMem)
-
-Bidirectional (`docs/roadmap/epics/agent-context-pack.md`, complete 2026-06-17):
-- **Brain → mini-ork:** planner/worker pull `cn_retrieve`, `cn_sessions_by_file`, and a UprPromptSubmit prefetch hook (`cn_retrieve + cn_inbox + cn_features_recent`); planner uses `/prompt-context/capsule` (kind-ordered, ~8KB cap); role-tailored ContextPacks map mini-ork's 8 node types to CN endpoints; prefetch markdown inlined atop worker prompts.
-- **mini-ork → brain:** `POST /agent/outcome` (EvoMem, arXiv 2511.01912) — after a worker stops, mini-ork posts the CN atom ids it consumed + outcome. CN bumps `last_accessed`, nudges `_cn_confidence_signal` ±0.05 (capped ±0.05/call, ±1.0 cumulative so one noisy worker can't pin a basin), stores evidence. Deliberately side-effect-light: **no re-consolidation/re-embedding** — only metadata `retrieve` already reads.
-
----
-
-## Part D — How the whole system learns (end to end)
-
-1. **A run executes.** mini-ork classifies the task, `decide()` picks a lane per node (learned advantage + ε-exploration), workers run, every step is written to `execution_traces` with cost/duration/verdict.
-2. **Reward is stamped.** An 8-item rubric grades the run → `reward_g` on every trace; PRM adds a dense per-node process score; verify writes success/failure/vacuous.
-3. **The policy updates (flywheel 1 — routing).** Reflect recomputes GRPO relative advantage per `(objective_domain, task_class, node_type, code_region)` group with recency-weighting, shrinkage, and EMA; `preferred_lane` shifts toward whichever lane beats its peers. Gradients + patterns are mined for prompt/topology improvements; GEPA suggests prompt rewrites (held-out, suggest-only).
-4. **The weights update (flywheel 2 — local model).** TraceOtter distils the same traces into an SFT dataset (action-grounded route labels, MemP skills, redacted, quality-gated), LoRA-trains a small local model, and gates on held-out route accuracy (72.4% vs 0% base) — not train loss. JitRL (design) will make this continual and cheap by nudging frozen-model logits from a `<s,a,reward>` memory bank.
-5. **The memory updates (flywheel 3 — context).** ContextNest extracts typed memories from the transcript, grades every claim against real tool receipts (observed/contradicted/absent), consolidates them into attractor basins, and serves a kind-ordered capsule back into the next run's planning — then takes outcome feedback to reweight what it surfaced.
-6. **Repeat.** Each run makes the next one route better, cost less (local absorption rises), and start with grounded memory — the compounding curve.
-
----
-
-## Part E — Honest caveats (do not paper over these)
-
-- **mini-ork:** GEPA is wired **suggest-only** under `MO_OPTIMIZER=gepa`; PRM same-family decontamination was removed pending a real `reviewer_model` column; there is **no Thompson/Beta/UCB** — ε-greedy is the only bandit.
-- **TraceOtter:** real code-vs-artifact drift — base model appears as Qwen3-4B (current exporter+eval), Qwen2.5-Coder-1.5B (stale vendored yaml), and Qwen2.5-0.5B (local smoke default); the emitted LF yaml says 3 epochs while the local trainer enforces 1. The **"$0.70/cycle" figure is not in the codebase** — treat it as an external estimate.
-- **ContextNest:** the elegant `src/context/*` neural-field/resonance layer is **largely NOT on the live request path** — retrieval scoring is reimplemented inline in `tools.rs`. Memories live in in-memory sidecars + WAL, not SQL/Qdrant. Embeddings are DeepInfra Qwen3 / local, **not Gemini**. The consolidation worker must run or the basin pipeline is dormant.
-- **General:** the impressive economics (84% token savings, quality parity) are modeled/held-out, not yet proven on an external customer workload.

-## Verified clean
-
-- All 9 recipe node types have handlers (no silent `(0,'done')` fall-through).
-- All 8 gate types have evaluators (no silent `defer`).
-- `SUBCOMMAND_REGISTRY` ↔ `bin/` wrappers consistent.
-- 123 `MO_*`/`MINI_ORK_*` env vars properly wired (set + documented).
-
-## Remaining debt (roadmap, not cleanup)
-
-- **Propensity stamping** (`route_source/route_explore/route_score`,
-  migration 0049): required for unbiased off-policy bandit evaluation
-  (roadmap Step 4). Owner should be `mini_ork/steering/decision_service.py`
-  — the bash twin (`decision_service_log_propensity`) is only exercised by
-  `tests/unit/test_router_followup.sh`.
-- **Env flags in test-only modules** (9): die with their parity-port module
-  on cutover (see `docs/migration/parity-ports.md`).
-- `MO_REFLECTION_BATCH` is set internally by the run loop AND read as an
-  operator knob — document the precedence when the loop is refactored.

The live API is covered by the strangler-fig parity gate `tests/unit/test_memory_py.py` (10 passed), which drives `lib/memory.sh` via subprocess. `test_memory.sh` — which had run 0 assertions since the API-drift guard landed — is therefore **retired** as a dead fixture: it tested the removed epic-CRUD model, not the current API, so removing it loses zero coverage (the current API's coverage lives in the parity gate).

-## 0. Brand Essence
-
-**What mini-ork is:** a task operating system for agents — classify → plan → execute → verify → reflect → improve.
-
-**The core belief the brand exists to express:** *multi-agent review only counts if the reviewers can't all share the same blind spot.* Everything visual and verbal ladders back to heterogeneity-by-construction and executable verification over vendor consensus theater.
-
-**Personality in one image:** a terminal-grade operator console — dense, mono, phosphor-on-black — commanded by a calm red master orc coordinating a fleet of green mini-orc agents. Serious instrument, not a toy; friendly crew, not a threat.
-
----
-
-## 1. Color Palette
-
-The palette is a **dark-first operator console**. Light-on-near-black is the default; there is no light theme in the shipping system. Colors are *signals*, not decoration — each hue carries a fixed operational meaning.
-
-### Base / Surface
-
-| Name | Hex | RGB | Usage |
-|------|-----|-----|-------|
-| BG | `#080A0B` | rgb(8,10,11) | App background, deepest layer |
-| Panel | `#0D1012` | rgb(13,16,18) | Panels, cards |
-| Panel 2 | `#11161A` | rgb(17,22,26) | Raised panel header gradient |
-| Panel 3 | `#161D22` | rgb(22,29,34) | Controls, buttons |
-| Raised | `#1B242A` | rgb(27,36,42) | Hover / active surface |
-| Hairline | `#1A2228` | rgb(26,34,40) | Grid lines, panel borders |
-| Edge | `#303C44` | rgb(48,60,68) | Strong borders, focus edges |
-
-### Text
-
-| Name | Hex | RGB | Usage |
-|------|-----|-----|-------|
-| Text | `#D6DDE2` | rgb(214,221,226) | Primary body / data |
-| Text 2 | `#AAB4BB` | rgb(170,180,187) | Secondary |
-| Text 3 (muted) | `#7C8890` | rgb(124,136,144) | Captions, muted |
-| Text 4 (chrome) | `#56626A` | rgb(86,98,106) | Labels, faint chrome |
-| Text 5 (ghost) | `#3C474E` | rgb(60,71,78) | Disabled / ghost |
-
-### Signal — the four operational hues
-
-| Name | Hex | RGB | Meaning (fixed) |
-|------|-----|-----|-----------------|
-| **Phosphor Green** | `#4FD1A0` | rgb(79,209,160) | OK · data · **heterogeneous** · primary brand signal |
-| **Amber** | `#E6B04A` | rgb(230,176,74) | Warn · pending · budget caution |
-| **Red** | `#F0584E` | rgb(240,88,78) | Alert · fail · destructive command |
-| **Cyan** | `#58B9C9` | rgb(88,185,201) | Link · focus · info |
-| Violet | `#9B8CDF` | rgb(155,140,223) | Secondary accent (rare) |
-
-> Rule: never use a signal color decoratively. Green means *good/verified*, red means *failed/destructive*. Miscoloring a passing state red is a brand violation, not just a UI bug.
-
-### Ork Brand Accents
-
-The "creature" palette — desaturated, earthy, used for identity surfaces (logo, hero, marketing), **not** for operational UI signal.
-
-| Name | Hex | RGB | Usage |
-|------|-----|-----|-------|
-| **Ork Red** | `#A52828` | rgb(165,40,40) | The master orc — primary brand mark color |
-| Ork Red Deep | `#6D1A1A` | rgb(109,26,26) | Shadow / gradient partner |
-| Ork Green | `#2F7A48` | rgb(47,122,72) | The mini-orc crew |
-| Ork Amber | `#B07A2C` | rgb(176,122,44) | Warm accent |
-
-### Model-Family Palette (product-specific)
-
-Heterogeneity-by-construction is the thesis, so **model families get named colors**. Use these consistently anywhere a family is attributed (lane maps, fingerprint views, trajectory).
-
-| Family | Hex | Vendor |
-|--------|-----|--------|
-| Opus | `#A394E8` | Anthropic |
-| Sonnet | `#E0975F` | Anthropic |
-| GLM | `#46C0B6` | Zhipu |
-| Kimi | `#5F97E6` | Moonshot |
-| Codex | `#D4B24F` | OpenAI |
-| Gemini | `#74C463` | Google |
-| None / unassigned | `#5A666E` | — |
-
-### Accessibility
-
-All defaults are light-on-near-black and clear AAA comfortably:
-
-| Pair | Approx. ratio | Level |
-|------|---------------|-------|
-| Text `#D6DDE2` on BG `#080A0B` | ~13:1 | AAA |
-| Phosphor Green `#4FD1A0` on BG | ~10:1 | AAA |
-| Amber `#E6B04A` on BG | ~10:1 | AAA |
-| Cyan `#58B9C9` on BG | ~8:1 | AAA (large/AA normal) |
-
-- Text 4/5 (chrome, ghost) are intentionally low-contrast **decorative** chrome — never place essential information there.
-- Focus is a 2px cyan ring on a BG-colored inset (`:focus-visible`), never removed.
-- Motion respects `prefers-reduced-motion` (CRT scanline, ping, shimmer all disable).
-
----
-
-## 2. Typography
-
-**Mono-first.** mini-ork is an operator instrument; the default typeface is monospace so data, IDs, costs, and code align on a grid. Inter is the *secondary* sans for prose surfaces (marketing, long-form docs).
-
-### Font Stack
-
-```css
---mono: 'JetBrains Mono', ui-monospace, 'SF Mono', Menlo, monospace;
---sans: 'Inter', system-ui, -apple-system, sans-serif;
-```
-
-Load: `JetBrains Mono` weights 400–800, `Inter` 400–600.
-Feature settings on body: `'zero', 'ss02'` (slashed zero, disambiguated glyphs), tracking `-0.01em`.
-
-### Type Scale (console)
-
-| Token | Size | Typical use |
-|-------|------|-------------|
-| micro | 9.5px | Eyebrows, tags, family chips |
-| xs | 10.5px | Labels, table headers |
-| sm | 11.5px | Table cells, secondary |
-| base | 12px | Body / default |
-| md | 13px | Emphasis body |
-| lg | 16px | Panel titles |
-| xl | 21px | Section headers |
-| 2xl | 30px | View headers |
-| display | 40px | Hero numerals |
-
-### Long-form / marketing scale (Inter)
-
-| Element | Weight | Size (Desktop / Mobile) | Line height |
-|---------|--------|-------------------------|-------------|
-| H1 | 700 | 40px / 30px | 1.2 |
-| H2 | 600 | 30px / 24px | 1.25 |
-| H3 | 600 | 21px / 18px | 1.3 |
-| Body | 400 | 16px / 16px | 1.55 |
-| Small | 400 | 14px / 14px | 1.5 |
-
-### Rules
-
-- Numbers use tabular figures (`font-variant-numeric: tabular-nums`) so costs and counts don't jitter.
-- Labels/eyebrows are **UPPERCASE, letter-spaced** (`0.13em`–`0.18em`), muted chrome color.
-- Prose (Inter) drops the tracking (`letter-spacing: 0`).
-
----
-
-## 3. Logo & Mark
-
-### Concept
-
-Two-part identity: the **wordmark** `mini-ork` (lowercase, mono) and the **mark** — a red master-orc glyph, optionally over a fleet of small green orc dots (the crew).
-
-### Variants
-
-| Variant | Use case |
-|---------|----------|
-| Wordmark | `mini-ork` lowercase, JetBrains Mono 700, Text color — headers, docs |
-| Bracket wordmark | `[mini-ork]` — terminal/console contexts, favicons of type |
-| Mark (master orc) | Ork Red `#A52828` glyph — app icon, avatar, small spaces |
-| Crew lockup | Red master orc + green mini-orc dots — hero, marketing |
-| Monochrome | Single Text-color version for limited-palette contexts |
-
-### Clear space & minimum size
-
-- Clear space = height of the mark on all sides.
-- Digital wordmark: 96px min width. Mark: 24px min.
-
-### Don'ts
-
-- Don't render the wordmark in Title Case or ALL CAPS — it is always lowercase `mini-ork`.
-- Don't recolor the master orc outside Ork Red / monochrome.
-- Don't map the ork "creature" reds/greens onto operational UI signals (green stays phosphor `#4FD1A0` in-app).
-- Don't add shadows, bevels, or gradients to the wordmark.
-- Don't hyphen-break or space the name (`mini ork`, `MiniOrk`, `Mini-Ork` are all wrong).
-

-
-## 4. Voice & Tone
-
-mini-ork's voice is the one already in the README and positioning docs: **an expert operator who leads with receipts and refuses to oversell.** It sounds like an engineer you trust because they tell you what *doesn't* work yet.
-
-### Personality
-
-| Trait | Meaning |
-|-------|---------|
-| **Direct** | Lead with the claim. Short sentences. Fragments allowed in-product. |
-| **Evidence-first** | Every strong claim carries a receipt — a command, a ρ value, a paper, an exit code. "The harshness table is the receipts." |
-| **Unhyped** | State limits plainly. A "Where we're honest about what it isn't (yet)" section is a feature, not a weakness. |
-| **Precise** | Use the exact term (`verifier`, `gradient`, `lane`, `task class`). Don't fuzz the mechanism. |
-| **Dry** | Wit is fine; exclamation and marketing gloss are not. |
-
-### Voice Chart
-
-| Trait | We Are | We Are Not |
-|-------|--------|------------|
-| Direct | "Pass/fail is an exit code, not an opinion." | "We help streamline your agentic workflows." |
-| Evidence-first | "ρ = 0.05–0.25 across 1–4 agents (Rajan 2025)." | "Studies show diversity improves results." |
-| Unhyped | "Self-evolution is class-restricted — don't oversell." | "Fully autonomous self-improving AI." |
-| Precise | "The coalition gate hard-blocks same-family degeneration." | "Smart routing keeps quality high." |
-| Confident | "This is the test we built mini-ork to pass." | "We think this might help, maybe." |
-
-### Tone by Context
-
-| Context | Tone | Example |
-|---------|------|---------|
-| README / marketing | Confident, benefit + receipt | "Every run starts smarter — and cheaper — than the last." |
-| Docs | Instructional, exact | "Run `mini-ork validate` before any real run." |
-| CLI / status output | Terse, mono, signal-colored | `verify → PASS (rc=0)` / `verify → vacuous` |
-| Error messages | Calm, actionable, no blame | "No verifiers declared — marked `vacuous`, not `success`. Add `success_verifiers` in `artifact_contract.yaml`." |
-| Success | Brief, factual | "Promoted candidate v0.3.1 — beat benchmark under budget." |
-| Limitations | Plain, owning the gap | "Krippendorff α gate — not built yet. v0.3 candidate." |

-| Revolutionary / game-changing | Hype; we lead with receipts |
-| Seamless / effortless | Vague; the product is an *instrument*, it rewards operators |
-| Leverage (verb) | Say "use" |
-| Synergy / holistic | Corporate jargon |
-| Best-in-class / world-class | Unprovable claim |
-| "AI-powered" as a value prop | Table stakes; describe the *mechanism* instead |
-| "Fully autonomous" (unqualified) | Contradicts the class-restricted self-evolution honesty |
-
-### Naming discipline
-
-Always lowercase **mini-ork**, even at the start of a sentence in body copy where possible; if a sentence must start with it, prefer restructuring. Never "Mini-Ork," "MiniOrk," or "MINI-ORK."

-## 5. Imagery & Illustration
-
-### The creature world
-
-- **Master orc:** friendly, modern, calm — a *coordinator*, not a warrior. Ork Red `#A52828`. Commands, doesn't fight.
-- **Mini-orcs (crew):** small, green `#2F7A48`, collaborative — each is an agent/lane. Shown working in connected bubble-workspaces.
-- **Setting:** clean, sci-fi operator environment (spaceship / command deck), never grimdark. The tone is competent and peaceful, matching "serious instrument, friendly crew."
-
-### Console / UI imagery
-
-- Hairline grids, phosphor-on-black, subtle CRT scanline + vignette (opacity ~0.5, `mix-blend-mode: overlay`) — always subtle, never at the cost of legibility.
-- Data over ornament: real tables, real trajectories, tabular numerals.
-
-### Illustration style
-
-- Flat with restrained gradients; 2px consistent stroke.
-- Palette-locked (creature palette for characters, signal palette for data).
-- Corners 3px (matches `--rad`).
-
-### Icons
-
-- Outlined, ~24px grid, ~1.5px stroke, minimal fill.
-- Sharp, small, mono-adjacent — they live in a dense console.
-

-## 6. Design Components
-
-Radii are **sharp** — this is an instrument, not a consumer app.
-
-| Element | Radius |
-|---------|--------|
-| Base (`--rad`) | 3px |
-| Slightly raised (`--rad-2`) | 5px |
-| Tags | 2px |
-| Pills / family chips | 2px |
-
-### Buttons
-
-| Type | Background | Text | Border |
-|------|------------|------|--------|
-| Default | Panel 3 `#161D22` | Text 2 | Hairline 2 |
-| Ghost | transparent | Text 3 | none |
-| Command (destructive) | Red wash `rgba(240,88,78,.11)` | Red `#F0584E` | Red `rgba(240,88,78,.3)` |
-
-Buttons are UPPERCASE, 24px tall, mono, letter-spaced `0.02em`.
-
-### Tags / status
-
-`tag-ok` (green wash), `tag-warn` (amber), `tag-err` (red), `tag-info` (cyan), `tag-mut` (neutral). Meaning is fixed to the signal palette.

-## 7. Messaging Architecture
-
-### Mission
-
-We give teams a task operating system for agents — classifying, planning, verifying, and remembering work across model families — so every run ships durable, verified artifacts instead of same-vendor consensus theater.
-
-### Vision
-
-A world where "multi-agent" means low-correlation evidence and executable checks — not one model family grading its own homework.
-
-### Value proposition
-
-For engineering teams running agentic work who need results they can trust, mini-ork is a task operating system that dispatches specialized agents across *distinct model families*, gates output through deterministic verifiers, and remembers every run. Unlike single-vendor agent frameworks, review independence is a structural property, not a hopeful prompt.
-
-### Positioning statement
-
-mini-ork is the operating system you build on top of Claude Code (or any single-vendor agent framework) when you want to pass the detection-fingerprint test — not just draw an agent graph.
-
-### Primary message
-
-**Stop letting one model family grade its own homework.**
-
-### Supporting messages
-
-| Message | Need it addresses | Proof point |
-|---------|-------------------|-------------|
-| Heterogeneous-family by construction | Independent review | `config/agents.yaml` maps lanes to GLM/Kimi/Codex/Opus/DeepSeek/MiniMax; coalition gate hard-blocks same-family panels |
-| Executable verification before opinion | Trustworthy pass/fail | Every recipe ships `verifiers/*.sh`; pass/fail is an exit code; empty verification is `vacuous`, never silent success |
-| Persistent trajectory memory | Runs that compound | `state.db` persists runs, gradients, lineage, cost; the planner sees the last N same-class runs |
-| Cost governance | Predictable spend | Budget gates halt the queue; cost is a first-class column, not an afterthought |
-| Honest about limits | Buyer trust | A published "what it isn't yet" section tied to the roadmap |
-
-### Elevator pitches
-
-- **10-second:** "mini-ork is a task OS for agents — it runs your work across different model families and verifies the output with real tests, not another AI's opinion."
-- **30-second:** Add the problem: single-vendor agent frameworks let one model family review its own work, so you get consensus theater. mini-ork enforces family diversity, gates every artifact through executable verifiers, and remembers every run so the next one is smarter and cheaper.
-- **60-second:** Add the receipts — Rajan 2025's ρ=0.05–0.25, the coalition gate, `state.db` trajectory metrics, and the class-restricted self-evolution honesty.

-## Closure evidence
-
-1. Production callers use the native Python modules; `bin/` compatibility
-   launchers re-exec the canonical `mini-ork` dispatcher.
-2. Former Bash parity tests were converted to standalone native unit tests.
-3. A global closure scan confirms no framework shell files remain in `lib/` or
-   `gates/`; full pytest, lint, validate, and garden gates verify the result.

-# Ported-module ownership — recursive migration plan
-
-_Status: Phase 0 inventory passed on 2026-07-20 at baseline `c7ccc512` with
-126/126 modules, zero deletion authorizations, Kimi history synthesis, GLM 5.2
-review, and 38/38 deterministic checks. The similarity seed unit is complete:
-pure ranking now lives at `mini_ork/similarity.py`, the context assembler uses
-its raw-score API, 30 focused tests and Pyright pass, and the GLM 5.2
-implementation review requires no repairs. Refresh Phase 0 after promotion
-before selecting the next unit._
-
-## Goal
-
-Give every module under `mini_ork/ported/` one explicit owner and one terminal
-decision:
-
-- **integrate** useful behavior into the canonical Python runtime;
-- **retain** an intentional boundary or dormant capability with a named owner;
-- **delete** code that has no caller, requirement, unique behavior, fixture, or
-  supported public contract.
-
-The migration is complete only when runtime behavior has one canonical
-implementation, callers and tests use it, obsolete Bash and duplicate Python
-implementations are retired, and the affected feature passes focused and
-end-to-end validation.
-
-## Why a new recursive plan is required
-
-The existing `self-migrate` recipe closes top-level entrypoint forks. It assumes
-an entrypoint-shaped unit: a Bash executable, a Python replacement, and inbound
-callers. Lower-level libraries do not always have that shape. A file can be:
-
-- ported but never imported;
-- duplicated inside a runtime module;
-- kept only as a parity or benchmark fixture;
-- an intentional external-process adapter;
-- unused today but still required by a documented product contract.
-
-Therefore, do not feed the whole `mini_ork/ported/` directory to
-`scripts/recursive-migrate.sh`. That script is a leaf-tail driver and cannot
-prove ownership of duplicated or dormant behavior.
-
-## Safety invariants
-
-1. Work from an isolated worktree created from current `main`.
-2. One ownership seam per change. Do not combine unrelated modules.
-3. Capture the old contract before changing either implementation.
-4. Never delete a file merely because a text-reference scan is empty.
-5. Preserve intentional subprocess boundaries for providers, Git, executable
-   verifiers, and other external tools unless their boundary is the named unit.
-6. A Bash file may be retired only after all runtime, test, integration, E2E,
-   security, benchmark, and fixture dependencies have moved or been explicitly
-   removed with replacement coverage.
-7. Use explicit Git pathspecs. Do not stage runtime state, credentials, local
-   provider configuration, generated reports, or unrelated cleanup.
-8. Before merge, inspect the complete diff for secrets and OSS readiness.
-9. Before and after implementation, audit the task requirements and relevant
-   `docs/` requirements. Any gap becomes a timestamped file under `docs/todos/`
-   and is requeued; it is not waived.
-10. A failed gate preserves evidence and leaves `main` unchanged.
-
-## Provider policy
-
-Agentic runs use only these lanes:
-
-| Responsibility | Lane | Purpose |
-|---|---|---|
-| discovery and history synthesis | Kimi | broad inventory and intent reconstruction |
-| implementation and focused repair | Codex | source and test changes |
-| ownership judgment and review | GLM 5.2 | independent classification and final verdict |
-| gates | deterministic verifier | commands, schemas, tests, and closure scans |
-
-Load Kimi and GLM credentials process-locally from
-`/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`. Use a temporary
-`MINI_ORK_HOME`; never copy credential values into the repository or run
-artifacts. MiniMax, DeepSeek, Opus, and implicit provider fallback are outside
-this plan.
-
-## The recursive unit
-
-The outer controller owns a queue of modules. Each queue item executes one
-acyclic mini-ork workflow and can finish only as `promote`, `defer`, or
-`rollback`.
-
-```mermaid
-flowchart TD
-    Q[Pick next ownership unit] --> D[Discover history, callers, duplicates]
-    D --> C[Classify active, duplicated, dormant, dead, or external adapter]
-    C --> K[Capture current behavior contract]
-    K --> T[Transform one ownership seam]
-    T --> V[Run deterministic validation stack]

-    P --> Q
-    X --> Q
-    F --> Q
-    Q -->|queue empty and global closure passes| E[Migration complete]
-```
-
-The apparent cycle is controlled outside the recipe. The planned recipe itself
-remains a DAG, as required by `schemas/workflow.schema.json`:
-
-1. `history_memory_mapper` — Kimi reconstructs original intent from Git,
-   ContextNest session evidence, current docs, and the Bash predecessor.
-2. `ownership_mapper` — deterministic scans produce the complete inbound,
-   outbound, duplicate, test, fixture, and benchmark map.
-3. `classifier` — GLM assigns a classification and proposed terminal decision.
-4. `contract_capture` — deterministic probes record behavior before edits.
-5. `migrator` — Codex makes one bounded ownership change.
-6. `contract_verifier` — parity or golden behavior checks.
-7. `feature_verifier` — focused unit/integration/E2E checks for the consumer.
-8. `closure_verifier` — checks sole ownership and retirement blockers.
-9. `requirements_audit` — checks the task, this plan, and relevant docs.
-10. `reviewer` — GLM emits the final evidence-backed verdict.
-11. `publisher` or `rollback` — emits a proposal; it never mutates `main`.
-
-The operator promotes a passing proposal. An agentic verdict cannot override a
-failed deterministic gate.
-
-## Phase 0 — report-only inventory
-
-Before editing code, create `ported-module-inventory.json` in the run directory
-with one row for every `mini_ork/ported/*.py` file. Do not commit the generated
-inventory.
-
-Each row must contain:
-
-- module path and Bash predecessor, if any;
-- public functions/classes and current runtime importers;
-- subprocess or source boundaries called by the module;
-- same or substantially equivalent behavior implemented elsewhere;
-- unit, integration, E2E, security, parity, benchmark, and fixture references;
-- current docs and product requirements;
-- relevant Git commits and ContextNest session IDs;
-- classification, proposed decision, owner, confidence, and unresolved risks.
-
-The inventory gate fails if any module is missing or any row lacks evidence for
-its proposed decision. Only after the report passes may the controller enqueue
-implementation units.
-
-## Classification and terminal decisions
-
-| Classification | Meaning | Default action |
-|---|---|---|
-| active | imported by a supported runtime path | move to a canonical package if needed; keep and test |
-| duplicated | useful behavior has two implementations | integrate one canonical implementation, then remove the duplicate |
-| dormant | no current caller, but history/docs preserve intent | retain with explicit owner or make a reviewed product decision |
-| dead | no caller, requirement, unique behavior, fixture, or public contract | delete code and obsolete tests/docs together |
-| external adapter | process boundary is part of the design | retain the boundary and document it |
-
-Deletion requires all of the following evidence:
-
-- no executable runtime caller, including dynamic path construction;
-- no distinct behavior absent from the proposed canonical owner;
-- no current product, operator, schema, or migration requirement;
-- no supported import/API contract;
-- no required test, benchmark, corpus, golden, or parity fixture;
-- affected tests pass after removal;
-- global closure scan finds no dangling reference.
-
-If one condition is unknown, classify the unit as `dormant` or `defer`; do not
-guess `dead`.
-
-## Per-module execution contract
-
-### 1. Discover
-
-- Reconstruct why the Bash and Python files were introduced and later changed.
-- Search ContextNest for the module, predecessor, consumer, and migration run.
-- Map static imports and dynamic subprocess/source invocations.
-- Identify duplicate algorithms and policy embedded in callers.
-- Record all tests and fixtures before deciding what is obsolete.
-
-### 2. Capture the contract
-
-Create a pre-change evidence artifact that defines inputs, outputs, exceptions,
-side effects, ordering, thresholds, rounding, stdout/stderr, exit codes, and
-best-effort failure behavior. Prefer deterministic golden cases. Use a live
-provider probe only when the contract crosses an LLM boundary.
-
-### 3. Transform one seam
-
-- **Integrate:** move or import the canonical implementation, repoint callers,
-  remove the duplicate, and preserve policy at the appropriate layer.
-- **Retain:** move it out of `ported/` when it is canonical, name the owner, and
-  attach direct tests; otherwise document why `ported/` is intentionally kept.
-- **Delete:** delete the implementation plus only the tests/docs/fixtures made
-  obsolete by that exact removal.
-
-### 4. Verify
-
-Every unit must pass, in this order:
-
-1. pre-change parity/golden evidence exists;
-2. focused unit and contract tests;
-3. affected integration/E2E/security test or feature-acceptance probe;
-4. focused Pyright with zero errors;
-5. runtime ownership scan: intended caller imports the canonical module;
-6. duplicate scan: the retired algorithm is not still embedded elsewhere;
-7. retirement scan across runtime, tests, scripts, docs, and benchmarks;
-8. `git diff --check` and an explicit-path scope review;
-9. secret and OSS-readiness review;
-10. the two requirements audits.
-
-For a provider-routing or LLM-boundary unit, add a real, non-dry-run provider
-probe with redacted evidence. For pure deterministic logic, do not spend a
-provider call merely to satisfy ceremony.
-
-### 5. Promote or roll back
-
-A passing unit is committed on its isolated branch using explicit pathspecs,
-then merged into a clean `main`, pushed to `origin`, and verified with:
-
-```bash
-test "$(git rev-parse main)" = "$(git rev-parse origin/main)"
-git merge-base --is-ancestor <unit-commit> origin/main
-```
-
-Before merge, a failing proposal is abandoned without touching `main`. After
-merge, rollback uses `git revert <unit-commit>` and reruns the same validation;
-never rewrite shared history.
-
-## Seed unit — `similarity.py`
-
-The first unit is deliberately preclassified as **duplicated**, pending fresh
-inventory confirmation:
-
-- `mini_ork/ported/similarity.py` contains the pure tokenization, term
-  frequency, cosine, and ranking logic.
-- the supported runtime behavior is duplicated inside
-  `mini_ork/context_assembler.py` rather than importing the port;
-- the original feature contract retrieves similar lessons from bug, gradient,
-  and learning records, applies a `0.15` threshold, keeps the top three per
-  source, and preserves citations and suggested fixes.
-
-Expected implementation shape:
-
-1. move the pure module to a canonical path such as `mini_ork/similarity.py`;
-2. import it from `context_assembler.py` and remove the duplicate algorithm;
-3. keep database access and retrieval policy in the context-assembler layer;
-4. sort using unrounded scores, rounding only the reported value;
-5. preserve missing-table best-effort behavior;
-6. add direct tests for exact lesson shape, threshold boundaries, ties,
-   top-three selection, and missing tables;
-7. delete the obsolete port test only if replacement coverage is demonstrably
-   stronger.
-
-This unit must not delete similarity behavior. Its purpose is to make the
-ported implementation the canonical runtime owner.
-
-### Similarity closure — 2026-07-20
-
-- `mini_ork/ported/similarity.py` moved to `mini_ork/similarity.py` without a
-  compatibility shim.
-- `mini_ork/context_assembler.py` imports `rank_raw`; the duplicated
-  tokenization, term-frequency, cosine, and ranking implementation is removed.
-- Database access, the three source tables, the 2,000-row cap, inclusive
-  `0.15` threshold, top-three-per-source selection, citations, suggested fixes,
-  four-decimal output, and missing-table best-effort behavior remain in the
-  context-assembler layer.
-- Raw scores determine ordering before reported values are rounded.
-- Focused verification: 30 pytest cases passed; focused Pyright reported zero
-  errors; mini-ork validate and garden completed with zero errors; GLM 5.2
-  review passed without required repairs.
-
-## Queue order after similarity
-
-Rebuild the exact queue from Phase 0 rather than copying an old filename list.
-Prioritize by dependency and proof value:
-
-1. duplicated deterministic logic already used by runtime callers;
-2. active native ports whose remaining callers still use Bash;
-3. wrapper ports that must become native before caller rewiring;
-4. reflection/gradient and remaining context-assembler surfaces;
-5. lower-level gate, steering, lifecycle, role, and artifact libraries;
-6. Bash integration/E2E tests and benchmark fixtures blocking retirement;
-7. dormant modules requiring an explicit product decision;
-8. provably dead leaves;
-9. intentional external adapters, normally retained.
-
-The refreshed queue must cover these non-skippable remaining program tracks:
-
-1. finish native `llm-dispatch` adoption by every remaining caller, then retire
-   `lib/llm-dispatch.sh` only after real-provider and closure evidence passes;
-2. migrate the separate `mini-ork-scheduler` entrypoint together with all of its
-   callers and tests as its own integration fork — completed on 2026-07-20 by
-   making `mini_ork.scheduler` canonical and retiring the Bash and duplicate
-   serial Python owners;
-3. close reflection/gradient and the remaining context-assembler surfaces,
-   including the similarity seed unit — completed on 2026-07-20: both
-   reflection libraries and `lib/context_assembler.sh` are retired, and their
-   unique contracts are native;
-4. rewire and retire lower-level gate, steering, lifecycle, role, and artifact
-   libraries one ownership seam at a time;
-5. convert the Bash integration/E2E suites and benchmark fixtures that are
-   genuine retirement blockers, preserving the behavior they protect.
-
-These tracks are completion requirements, not a static filename queue. Phase 0
-may split them into smaller dependency-ordered units but may not omit them.
-
-The next unit is selected only after the previous unit is merged, pushed, and
-the global inventory is refreshed. This prevents a stale call graph from
-authorizing later deletions.
-
-## Run artifacts and verdict
-
-Each unit stores these generated artifacts under its run directory:
-
-- `ownership-map.json`
-- `history-intent.md`
-- `pre-change-contract.json`
-- `migration.diff`
-- `verification.json`
-- `requirements-audit-1.md`
-- `requirements-audit-2.md`
-- `verdict.json`
-
-`verdict.json` passes only when:
-
-```text
-pass = contract_pass
-    && feature_pass
-    && sole_owner_pass
-    && retirement_blockers_clear
-    && requirements_audit_1_pass
-    && requirements_audit_2_pass
-    && oss_scope_pass
-```
-
-Run artifacts are evidence, not source deliverables, and are not committed.
-
-## Completion conditions
-
-The recursive migration stops only when all conditions hold:
-
-- every Phase 0 inventory row has a terminal decision and named owner;
-- no useful implementation remains orphaned under `mini_ork/ported/`;
-- no supported behavior has multiple canonical implementations;
-- every retired Bash library has zero executable, test, fixture, and benchmark
-  dependency;
-- reflection/gradient, context assembly, gates, steering, lifecycle, roles,
-  artifacts, integration/E2E tests, and benchmark blockers are closed or
-  explicitly retained;
-- `mini-ork validate`, `mini-ork garden`, focused type checks, affected tests,
-  feature acceptance, and global closure checks pass;
-- the final migration commit is an ancestor of `origin/main`, and local `main`
-  equals `origin/main`.
-
-Queue exhaustion alone is not completion. The final inventory and closure scan
-must independently prove the end state.

-# Python migration — completion plan (historical)
-
-_Written 2026-07-18 after a full audit and updated 2026-07-20 after the
-execute-fork closure. Superseded by the 2026-07-29 framework-runtime closure._
-
-> **Historical plan.** The remaining engine cutover described below is
-> complete: retired `lib/` and `gates/` implementations have no executable,
-> test, fixture, or benchmark dependency. Keep this document for its
-> dependency analysis; do not use its Bash commands or live-status statements
-> as current operating instructions.
-
-## State
-
-- **Ports exist** for nearly every `lib/*.sh` (`mini_ork/ported/*.py`), merged to main weeks ago.
-- **Done (PR #179):** 16 leaf libs retired, BYO providers (`config/providers.yaml` read by the
-  Python core), and the **routing brain is native** — `learning_governed_lane` calls
-  `decision_service.decide()` in-process (byte-parity verified, EPSILON=0).
-- **Top-level migration cycle complete:** verify, reflect, classify, plan, CLI,
-  and execute are Python-owned. `mini_ork/cli/execute.py` is the
-  sole executor, the CLI routes to it in-process, and `bin/mini-ork-execute` is
-  retired. Provider, git, and executable verifier subprocesses remain
-  intentional external boundaries.
-- **Completed globally (2026-07-29):** framework runtime modules and libraries
-  have been cut over to Python. Phase 5 release verification remains a
-  separate release-management task.
-
-`flip/runtime-default-python` is **stale** (last commit Jul-10, 43 behind main) — abandon it;
-build from main.
-
-## The remaining libs, by category (this is the whole job)
-
-### 1. Native ports → just rewire the caller (cheap, but verify parity first)
-The port is already native; the engine just calls the bash instead. Rewire = replace the
-`subprocess` with an `import`, **after** proving byte-parity deterministically.
-
-| lib | port native? | engine shell-out site | note |
-|---|---|---|---|
-| `decision_service` | ✅ | execute.py | **DONE** (PR #179) |
-| `llm-dispatch` | ✅ (native on execute, invoke-prompt, profile answerer, review, comparative opinions, and reflection gradients) | Provider/telemetry/tool-grant fixtures | Runtime review callers are closed; convert the remaining dispatcher fixtures before retirement |
-| `gate_bootstrap` | ✅ | non-execute callers | Execute now uses native bootstrap/registry behavior; retire the Bash lib only after every other caller moves |
-| `gradient_extractor` | ✅; Bash retired | none | Native dispatch, framework filtering, watermark, persistence, dedup, and standalone contracts own the full surface |
-
-### 2. Wrapper ports → native-ize first (real porting), then rewire
-The "port" still shells to its own bash. Reimplement the shelled functions in Python.
-
-| lib | shell-outs in port | lines |
-|---|---|---|
-| `gate_registry` | execute seam closed; other callers remain | 450 |
-| `lane-helpers` | execute seam closed; other callers remain | 332 |
-| `config_resolve` | 1 | 94 |
-| `rho_aggregator` | 1 | 179 |
-
-### 3. No port → port from scratch
-| lib | lines |
-|---|---|
-| `trace_store` | — |
-| `lane_router` | ✅; reflect caller native | Bash callers/tests below the frontier remain |
-| `intervention_gate` | native execute extension point added; no shipped Bash hook existed |
-
-### 4. Retirement blockers (even after the port is native)
-A lib can only be `git rm`'d when **all** of these are clear — check by basename across the tree:
-- no runtime shell-out from `mini_ork/` (grep `subprocess|bash -c|source` + `X.sh`, incl. `$LIB/X.sh` variable paths)
-- no `source`/`. `-include in any `tests/**/*.sh` (bash integration tests source libs via `$LIB/X.sh`)
-- not pinned by `benchmark/tasks/*` (~31 libs are gold/parity fixtures there)
-- no `.py` parity test `shutil.copy`ing the bash as a fixture
-
-Coupling hubs to break first (each unblocks a group):
-- `tests/integration/test_meta_orchestrator_loop.sh` → epic_graph, topology, role_evolver (Python port `test_meta_orchestrator_loop_py.py` already written this session)
-- `tests/integration/test_gate_grounded_rejection.sh` → the 5 gates + gates_common (Python port already written)
-- `tests/integration/test_autonomous_epic_pipeline.sh` → epic_graph; its context assembler call is native
-- the e2e suites → promotion_gate, version_registry, trace_store, benchmark_suite
-
-## Execution pattern (proven this session)
-
-Per subsystem, in this order — **never a blind sweep** (a wrong port breaks every dispatch and the parity tests are being removed):
-1. **Verify byte-parity deterministically** — native fn vs bash fn, exploration/randomness disabled, over representative inputs. Only proceed at 0 mismatches.
-2. **Rewire the caller** — replace `subprocess.run(["bash","-c","source X.sh; fn …"])` with `from mini_ork.ported import X; X.fn(…)`.
-3. **Verify** — pytest (parity + affected) + `pyright: 0 errors` + a **real run** (`MINI_ORK_DRY_RUN=0`) confirming the flow, not just dry-run for LLM-boundary changes.
-4. **Retire** — once §4 blockers clear, port the bash tests to standalone Python, drop benchmark fixture refs, `git rm` the bash. Explicit pathspec.
-
-### Completed caller unit: `mini-ork-invoke-prompt` — 2026-07-20
-
-- The stable public path is retained as a thin Python launcher.
-- All three BDD-first recipe callers use the utility's documented
-  `MINI_ORK_PROMPT_FILE` input contract.
-- `mini_ork.cli.invoke_prompt` calls the native dispatcher
-  in-process and temporarily overlays the invocation environment so provider,
-  routing, timeout, telemetry, and budget settings retain subprocess semantics.
-- Its golden-contract suite does not create `lib/llm-dispatch.sh`; therefore a
-  passing test proves this caller cannot silently fall back to Bash.
-- The public launcher completed a real GLM 5.2 prompt with process-local
-  credentials and a temporary provider registry; the focused invoke/dispatcher
-  suite passed 19 tests and focused Pyright reported zero errors.
-- The BDD-first dry-run E2E passed 18 assertions; validation passed and garden
-  retained only the pre-existing missing operator env-var-document warning.
-- The trace-store subprocess remains below the migration frontier as a separate
-  ownership seam.
-- This unit does **not** authorize deleting `lib/llm-dispatch.sh`; the remaining
-  caller and fixture blockers above still have to close.
-
-### Completed caller unit: `profile_answerer.py` — 2026-07-20
-
-- The planner-injected path was already native; the standalone/default path
-  now calls `mini_ork.dispatch.llm_dispatch` in-process too.
-- Commit `00176709` is the latest provider contract: Kimi primary plus one Kimi
-  retry on failure or whitespace. The retirement audit corrected a native-port
-  regression that had restored the older, banned DeepSeek primary.
-- Standalone golden contracts now preserve prompt bytes, validation, fence and
-  balanced-object recovery, completeness checks, exact JSON persistence, and
-  native Kimi retry behavior without sourcing a Bash oracle.
-- The planner was already the only production inbound caller. The web smoke
-  assertion now verifies native ownership and `lib/profile_answerer.sh` is
-  retired, closing this fork and one more `llm-dispatch.sh` blocker.
-
-### Completed caller unit: `pre_push_review.py` — 2026-07-20
-
-- The sequential LLM panel calls native `mo_llm_dispatch` in-process and no
-  longer checks for or sources `lib/llm-dispatch.sh`.
-- Panel order, Gemini exclusion, timeout, four-turn limit, fail-open behavior,
-  JSON recovery, normalization, and eight-issues-per-lens cap are preserved.
-- Five focused tests and focused Pyright passed. A no-Bash fixture proves
-  ownership closure for this Python caller.
-- A real single-lens GLM 5.2 panel probe passed with process-local credentials
-  and the temporary provider registry; no MiniMax request ran.
-- `bin/mini-ork-review` plus `lib/pre_push_review.sh` remain a separate fork;
-  this caller unit does not authorize their deletion or dispatcher retirement.
-
-### Completed ownership fork: public pre-push review — 2026-07-20
-
-- `mini_ork.pre_push_review` is the sole implementation, combining the
-  CLI-complete runtime with native Codex/Kimi/GLM panel dispatch.
-- `bin/mini-ork-review` is a direct Python launcher; the Bash library and the
-  duplicate `mini_ork.ported.mini_ork_review` module are retired.
-- Standalone contracts cover persistence, heuristics, policy, CLI formatting,
-  forwarding, LLM normalization/fail-open behavior, and long unified diffs.
-- This closes the review runtime blocker, but does not authorize dispatcher
-  retirement while provider, telemetry, retry, artifact, and tool-grant
-  fixtures still source `lib/llm-dispatch.sh`.
-
-### Completed caller unit: `scripts/comparative-opinions.sh` — 2026-07-20
-
-- The Bash orchestration script now invokes the native dispatcher module and
-  no longer sources `lib/llm-dispatch.sh`.
-- Ten-lens background execution, output/error files, status markers, manifest,
-  and summary behavior remain unchanged.
-- A deterministic acceptance test exercised all ten default calls with no Bash
-  dispatcher library; shell syntax and focused Pyright passed.
-- A real script-level probe ran two `glm_current` lenses, produced substantive
-  opinions and a valid manifest, and made no MiniMax request.
-- `MO_COMPARATIVE_FAMILIES`, `MO_COMPARISON_DOC`, and `MO_IMPROVEMENT_DOC`
-  permit bounded/operator-selected runs; defaults retain the historical five
-  families and canonical research documents.
-
-### Completed integration fork: `mini-ork-scheduler` — 2026-07-20
-
-- `bin/mini-ork-scheduler` is a stable direct Python launcher for the canonical
-  `mini_ork.scheduler` implementation.
-- The canonical owner activates the bounded concurrent epic pool controlled by
-  `MO_SCHED_MAX_PARALLEL`; a CLI-main timing contract proves three independent
-  epics do not silently fall back to serial execution.
-- The duplicate serial `mini_ork.ported.mini_ork_scheduler`, the legacy Bash
-  scheduler body, and their Bash-oracle test were retired.
-- Conductor and autonomous-pipeline callers keep the public executable path.
-  Generated verification hints compile the launcher as Python instead of
-  applying `bash -n` to it.
-- Fourteen focused contracts, 26 combined scheduler/conductor/epics caller
-  tests, and the 13-assertion autonomous epic pipeline passed; Pyright reported
-  zero errors, validation passed, and garden reported zero errors with the
-  pre-existing missing env-var documentation warning.
-
-### Completed caller unit: native reflection gradient boundary — 2026-07-20
-
-- The default Python gradient extractor calls the native dispatcher in process
-  with the established `gradient-extract` node, 120-second timeout, five-turn
-  cap, and `MINI_ORK_GRADIENT_MODEL` (`codex` by default).
-- Fenced, prose-wrapped, complete, and truncated JSON arrays retain recovery;
-  missing evidence/confidence fields default to trace id and `0.5`.
-- The native reflection pipeline now owns extract, store, and schema defaults;
-  injection remains only as a deterministic extension/test seam.
-- Twenty-nine focused tests and focused Pyright passed. A real GLM 5.2 probe
-  extracted three valid gradients from a persisted failed-verifier trace; no
-  MiniMax or DeepSeek request ran.
-- This closes the production caller edge. The Bash gradient/reflection libraries
-  and their Bash tests remain until the independent retirement fork closes.
-
-### Completed contract unit: reflection retirement prerequisites — 2026-07-20
-
-- Framework-internal `__*` traces are excluded before gradient dispatch, and
-  an evidence watermark makes overlapping reflection windows idempotent.
-- D5 per-node credit apply/restore is native, gamma-clamped, transient, and
-  restored in a `finally` block around router recomputation.
-- The public reflect entrypoint calls `mini_ork.lane_router` directly; it no
-  longer sources `lib/lane_router.sh` for this side channel.
-- Thirty-three focused Python tests, 23 legacy contract checks, focused
-  Pyright, reflect acceptance, and validation passed; the one legacy skip and
-  garden warning are unchanged environment/documentation baselines.
-- Physical deletion remains a separate fork because unique Bash semantic
-  dedup, writeback, integration, and E2E contracts must first become
-  standalone Python tests.
-
-### Completed retirement unit: native reflection and gradients — 2026-07-20
-
-- Removed the two legacy libraries after converting both Python parity suites
-  to standalone golden/database contracts.
-- Ported the unique cross-target containment dedup, trace-noise semantic dedup,
-  distinct-intent preservation, and pattern-miner-to-promotion writeback tests.
-- Rewired the reflection and seven-stage self-improvement E2Es to invoke native
-  gradient/reflection APIs while preserving their still-Bash downstream stages.
-- Removed five redundant Bash-only suites, removed the retired libraries from
-  doctor/recursive-migration metadata, and retained D1b/D4 router coverage
-  without its former reflection dependency.
-- The repository-wide suite passed 1,831 tests with 28 expected skips; focused
-  Pyright, both rewired E2Es, reflect acceptance, and validation passed. Garden
-  retained only the pre-existing missing operator env-var-document warning.
-
-## Tooling
-- **framework-edit** must use a dedicated temporary runtime home with only
-  Kimi, Codex, and GLM lanes; do not edit the user's `.mini-ork` policy and do
-  not route migration work through MiniMax. Drive a subsystem with
-  `MO_ALLOW_FRAMEWORK_CWD=1 MINI_ORK_PROFILE_GATE=0 bin/mini-ork run framework-edit <kickoff>`;
-  **harvest from the implementer worktree**, not `review-diff.patch` (capture
-  is unreliable).
-- `scripts/recursive-migrate.sh` — safety-gated per-lib driver (skips runtime-shelled/bash-test-sourced/benchmark-pinned; halts on engine break). Good for the leaf-ish tail, not the core.
-
-## Recommended order (ROI × safety)
-1. `llm-dispatch` boundary — biggest lever; do one caller at a time with real-LLM parity.
-2. Wrappers: `gate_registry` → then `gate_bootstrap` rewire; `lane-helpers`; `config_resolve`; `rho_aggregator`.
-3. Remaining ownership hubs: `trace_store`, `lane_router`, `intervention_gate`.
-4. Retirement cleanup: port the bash integration/e2e tests + repoint benchmark fixtures, then delete the freed bash.
-
-Realistic size: ~24K lines of remaining bash, most load-bearing. This is a multi-week, per-subsystem
-project — drive it deliberately, verify each with a real run, and it converges to zero `lib/*.sh`.

-# Remaining Dispatcher Migration — Sub-Handoff
-
-Status: active after `main` commit `be2fa515` (2026-07-20).
-
-This document covers only the dispatcher workstream. The master handoff for the
-whole migration program is
-`docs/migration/remaining-migration-full-handoff.md`.
-
-## Objective
-
-Retire the remaining Bash dispatcher fixtures and, only after all runtime,
-test, integration, benchmark, and source-shape references are closed, retire
-`lib/llm-dispatch.sh` itself.
-
-Do not delete the dispatcher merely because a Python port exists. Each unit must
-prove that the native implementation owns the behavior and that replacement
-coverage exists.
-
-## Current baseline
-
-Remote `origin/main` is `be2fa515`.
-
-Already merged native slices:
-
-- `91861459` — native executable transcript writer and transcript tests.
-- `5cd816ae` — native retry contract tests; Bash retry fixture retired.
-- `24220991` — native secret-redaction tests; Bash redaction fixture retired.
-- `ff74a68f` — native `llm_calls` ledger contract; Bash ledger fixture retired.
-- `be2fa515` — native tool-grant behavior coverage.
-
-The following remain intentionally live because their Bash contracts are not
-fully retired:
-
-- `lib/llm-dispatch.sh`
-- `tests/test_provider_registry.sh`
-- `tests/unit/test_providers_live.sh`
-- `tests/unit/test_provider_wrappers.sh`
-- `tests/perf/test_duration_capture.sh`
-- the provider/cost portions of
-  `tests/integration/test_dispatch_telemetry_gate.sh`
-- execute-gate portions of
-  `tests/integration/test_dispatch_telemetry_gate.sh`
-- `tests/unit/test_run_artifacts.sh`
-- any remaining direct dispatcher references found by the closure scan
-
-## Non-negotiable safety rules
-
-1. Work in a fresh worktree from current `origin/main`.
-2. One fixture or one tightly coupled contract group per commit.
-3. Preserve the Bash fixture until equivalent native coverage passes.
-4. Do not modify user-owned checkout state under `/Volumes/docker-ssd/ps/mini-ork`.
-5. Stage explicit migration files only. Never stage secrets, run databases,
-   provider configs, generated reports, temporary homes, or unrelated cleanup.
-6. Never print or commit credential values.
-7. Use only Codex, Kimi, and GLM lanes. MiniMax, DeepSeek, Opus, and implicit
-   fallback are forbidden for migration work.
-8. Load credentials process-locally from the operator wrappers under
-   `~/ps/scripts`; do not copy values into the repository or run artifacts.
-9. A failed gate leaves `main` unchanged and preserves evidence in the isolated
-   worktree.
-
-## Remaining work queue
-
-### 1. Finish tool-grant fixture retirement — DONE
-
-`tests/unit/test_tool_grants.sh` is retired. Its unique coverage was ported
-into native tests in `tests/unit/test_tool_grants_py.py`:
-
-- real `recipes/code-fix/workflow.yaml` producer resolution
-  (`test_real_workflow_producer_resolution`);
-- undeclared implementer/planner/reviewer defaults
-  (`test_undeclared_nodes_fall_through_to_type_defaults`);
-- `mcp__<server>` rendering (existing `test_mcp_rendering_and_claude_argv`);
-- subprocess argv contract for the canonical Python backend — a real
-  `python3 -m mini_ork.dispatch` run against a stub `claude` asserting
-  `--allowedTools`, `--strict-mcp-config`, `--mcp-config`, and that
-  `--permission-mode bypassPermissions` survives the grant insertion
-  (`test_python_dispatch_subprocess_folds_tool_grants`);
-- the dead Context7 instruction check on `bin/_worker-launcher.sh`
-  (`test_worker_launcher_context7_instruction_resolved`);
-- the implementer-has-no-comms/web-MCP structural invariant
-  (`test_implementer_profile_has_no_comms_or_web_mcp`);
-- the `providers.py` grant-flag source contract
-  (`test_providers_source_references_all_grant_flags`).
-
-The only assertions deliberately dropped were the `grep -c ... lib/llm-dispatch.sh`
-source-shape checks: those asserted content of the Bash file being retired and
-are superseded by the `providers.py` grant-flag contract above. The Bash
-argv path is not re-tested because Python is now the canonical dispatch owner.
-
-Regression guard:
-
-```bash
-python3 -m pytest tests/unit/test_tool_grants_py.py -q -p no:cacheprovider
-python3 -m pyright mini_ork/dispatch/providers.py
-```
-
-### 2. Convert provider registry and wrapper fixtures
-
-Native registry resolution lives in `mini_ork.dispatch.providers`.
-
-Remaining Bash dependencies are primarily in:
-
-- `tests/test_provider_registry.sh`;
-- `tests/test_provider_wrappers.sh`;
-- `tests/test_providers_live.sh`;
-- `tests/perf/test_duration_capture.sh`.
-
-Separate deterministic registry behavior from live-provider probes. Convert
-the deterministic cases first:
-
-- executable registry entry resolution;
-- OpenAI-compatible environment propagation;
-- Anthropic-compatible environment/model propagation;
-- wrapper precedence;
-- missing-key and unknown-lane failures;
-- duration sidecar behavior using a stub provider.
-
-Live provider probes must remain opt-in and must use only approved Codex, Kimi,
-or GLM credentials. Never use MiniMax or DeepSeek.
-
-### 3. Split and retire the telemetry gate fixture
-
-`tests/integration/test_dispatch_telemetry_gate.sh` currently combines four
-contracts:
-
-1. executable transcript sidecar merge and protocol stripping;
-2. Codex usage harvesting and estimated cost sidecar;
-3. native execute `needs_answers` gate;
-4. execute-gate override behavior.
-
-Transcript behavior is natively covered by:
-
-- `mini_ork/dispatch/transcripts.py`;
-- `tests/unit/test_dispatch_transcripts_py.py`.
-
-The next agent should split the remaining cost and execute-gate checks into
-standalone Python/integration tests before deleting the Bash gate file.
-
-Cost checks must use a stub `codex` executable and injected rates. They must
-prove:
-
-- `turn.completed` usage is harvested;
-- input/output token sidecars are correct;
-- injected rates produce the expected cost;
-- no network request is made.
-
-Execute-gate checks must prove:
-
-- `plan_status=needs_answers` exits with code `6`;
-- `task_runs` becomes `failed|BLOCKED`;
-- one `execute_blocked` event is emitted;
-- `blocked.json` is written;
-- `MINI_ORK_EXECUTE_GATE=0` bypasses the gate in dry-run mode.
-
-### 4. Convert artifact and duration fixtures
-
-Inspect:
-
-- `tests/unit/test_run_artifacts.sh`;
-- `tests/perf/test_duration_capture.sh`.
-
-Use native `mini_ork.dispatch.telemetry.persist_artifact` and the existing
-duration sidecar contract. Preserve path validation, hash/size registration,
-and zero-duration failure behavior. Benchmark fixtures must remain provider-free
-and deterministic.
-
-### 5. Final dispatcher closure
-
-After all fixture groups are migrated, run a repository-wide scan:
-
-```bash
-rg -n 'llm-dispatch\.sh|source .*llm-dispatch|\. .*llm-dispatch' \
-  bin lib mini_ork recipes scripts tests config docs
-```
-
-Classify every surviving reference as one of:
-
-- executable runtime edge — must be removed;
-- test/fixture edge — must be migrated or explicitly retained as historical;
-- documentation/history — may remain only when clearly historical.
-
-Only then consider deleting `lib/llm-dispatch.sh` and any now-obsolete Bash
-tests. Run the full closure and acceptance gates after deletion.
-
-## Required validation stack per unit
-
-Run in this order:
-
-1. Focused native tests for the exact fixture.
-2. Affected integration/E2E/security test.
-3. Focused Pyright on changed Python modules.
-4. `bin/mini-ork validate`.
-5. `bin/mini-ork garden` (pre-existing operator-env warning is acceptable;
-   new errors are not).
-6. `git diff --check`.
-7. Explicit diff review for secrets, generated state, and unrelated files.
-8. Requirements audit against this handoff and
-   `docs/migration/ported-module-ownership-recursive-plan.md`.
-
-For final dispatcher retirement also run:
-
-```bash
-python3 -m pytest -q -p no:cacheprovider
-python3 -m pyright mini_ork
-bin/mini-ork validate
-bin/mini-ork garden
-git diff --check
-```
-
-The broad suite may contain known state-dependent skips and existing Starlette
-deprecation warnings. New failures must be isolated and fixed before promotion.
-
-## Merge and push protocol
-
-For every passing unit:
-
-```bash
-git status --short
-git diff --check
-git add <explicit migration files only>
-git commit -m '<conventional migration message>'
-
-cd /Volumes/docker-ssd/ps/mini-ork-frc
-git fetch origin main
-git merge --ff-only <unit-branch>
-git push origin main
-test "$(git rev-parse main)" = "$(git rev-parse origin/main)"
-git merge-base --is-ancestor <unit-commit> origin/main
-```
-
-If fast-forward merge is impossible, stop and reconcile from fresh
-`origin/main`; do not force-push or reset shared history.
-
-## Completion criteria
-
-Migration is complete only when:
-
-- every runtime caller uses native dispatch;
-- all provider, retry, telemetry, artifact, cost, tool-grant, and execute-gate
-  contracts have native coverage;
-- no executable or test reference to `lib/llm-dispatch.sh` remains;
-- the full validation stack passes;
-- the final diff is OSS-ready and contains no credentials or local state;
-- the retirement commit is merged into `main` and verified on `origin/main`.
-
-If any requirement is unknown, classify it as deferred and document the exact
-evidence gap in a new `docs/todos/<timestamp>-*.md` file rather than deleting
-the Bash implementation.

-# Complete Remaining Bash-to-Python Migration — Agent Handoff
-
-Status: archived as a historical handoff on 2026-07-29.
-
-> **Closure update.** The final framework Bash runtime was removed after its
-> callers, fixtures, gates, provider lanes, and compatibility launchers were
-> rewired to native Python. `lib/` and `gates/` now contain no shell runtime
-> files; the remaining shell files are external integration or compatibility
-> surfaces that delegate to Python. The inventories and commands below explain
-> the original dependency analysis; they do not describe live Bash ownership.
-> Phase 5 release verification and the separate historical-documentation sweep
-> remain follow-up work.
-
-This is the master handoff for the **whole remaining migration program**. The
-dispatcher work is only one track. Its detailed sub-handoff is
-`docs/migration/remaining-dispatcher-fixture-handoff.md`.
-
-## Mission
-
-Finish ownership migration from legacy Bash implementations and fixtures to
-the supported Python runtime while preserving every product, operator,
-integration, security, observability, learning, and public-CLI contract.
-
-The work is complete only when every module has an explicit owner and terminal
-decision, every retired Bash library has zero executable/test/fixture/benchmark
-dependents, the complete validation stack passes, and the final commits are on
-`origin/main`.
-
-## Start here
-
-Read these documents before discovery or edits:
-
-1. `AGENTS.md`
-2. `docs/migration/remaining-migration-handoff.md`
-3. `docs/migration/ported-module-ownership-recursive-plan.md`
-4. `docs/migration/self-migrate-feature-manifest.md`
-5. `docs/migration/remaining-dispatcher-fixture-handoff.md`
-6. the task-, architecture-, operator-, and test-related documents for the
-   selected ownership unit
-
-The historical Phase 0 report covered 126 ported modules at `c7ccc512`. It is
-not a current deletion authorization. Refresh the live inventory from current
-`origin/main` before selecting each new unit.
-
-## Current promoted state
-
-The top-level runtime forks are complete:
-
-- verify;
-- reflect and gradient retirement;
-- classify;
-- plan;
-- CLI;
-- execute;
-- scheduler;
-- context assembler and similarity ownership;
-- profile answerer;
-- invoke-prompt;
-- comparative opinions;
-- pre-push review entrypoint and runtime consolidation.
-
-Recent lower-level dispatcher-related commits already on `main`:
-
-- `91861459` — native executable transcript writer;
-- `5cd816ae` — native retry fixture and Bash retry-test retirement;
-- `24220991` — native secret-redaction fixture and Bash-test retirement;
-- `ff74a68f` — native `llm_calls` ledger fixture and Bash-test retirement;
-- `be2fa515` — initial native tool-grant contracts;
-- `0bfdc3f6` — dispatcher sub-handoff.
-
-Do not repeat these completed units. Revalidate them only when an adjacent
-change can affect their contracts.
-
-## Migration model
-
-One queue item is one ownership seam. Each unit follows:
-
-```text
-refresh inventory
-  -> reconstruct history and requirements
-  -> map all callers/tests/fixtures
-  -> capture old behavior
-  -> implement one canonical owner
-  -> rewire all in-scope callers
-  -> replace obsolete fixtures
-  -> prove sole ownership
-  -> audit requirements twice
-  -> commit, merge, push
-  -> refresh inventory again
-```
-
-Never migrate the entire `mini_ork/ported/` directory mechanically. A port may
-be active, duplicated, dormant, dead, or an intentional external adapter.
-
-## Complete remaining workstreams
-
-The exact file queue must be regenerated, but none of these workstreams may be
-omitted.
-
-### A. Dispatcher, provider, telemetry, and tool-grant closure
-
-Canonical owners:
-
-- `mini_ork.dispatch.*`
-- `mini_ork.dispatch.llm_dispatch`
-- `mini_ork.dispatch.transcripts`
-
-Remaining work includes provider registry/wrapper fixtures, live-provider
-boundaries, tool-grant source-shape and subprocess coverage, Codex usage/cost
-sidecars, duration capture, run artifacts, execute-gate fixture splitting, and
-the final retirement of `lib/llm-dispatch.sh`.
-
-Follow `docs/migration/remaining-dispatcher-fixture-handoff.md` for the exact
-subqueue and its validation rules.
-
-### B. Gate framework and safety gates
-
-Known Bash/Python ownership pairs include:
-
-- `lib/gate_bootstrap.sh` / `mini_ork.gates.gate_bootstrap`
-- `lib/gate_registry.sh` / `mini_ork.gates.gate_registry`
-- `lib/gates_common.sh` / `mini_ork.gates.common`
-- `lib/coalition_gate.sh` / `mini_ork.gates.coalition_gate`
-- `lib/circuit_breaker.sh` / `mini_ork.recovery.circuit_breaker`
-- `lib/adaptive_stability.sh` / `mini_ork.gates.adaptive_stability`
-- `lib/cw_por.sh` / `mini_ork.gates.cw_por`
-- `lib/honest_ci_gate.sh` / `mini_ork.gates.honest_ci_gate`

-- `lib/citation_verifier_mechanical.sh` /
-  `mini_ork.gates.citation_verifier_mechanical`
-- `lib/promotion_gate.sh` / `mini_ork.gates.promotion_gate`
-
-Live shell consumers include `gates/coalition.sh`, `gates/stability.sh`,
-`gates/liveness.sh`, `gates/panel-health.sh`, `gates/synthesis-promote.sh`,
-oracle auto-wire tests, promotion tests, and the learning/evaluation stack.
-
-Migrate gates as dependency clusters. `promotion_gate` cannot retire safely
-before benchmark, utility, version registry, and gate-registry dependencies are
-native or explicitly retained external boundaries.
-
-Required behavior coverage includes return codes, fail-open/fail-closed rules,
-threshold boundaries, evidence payloads, registry lookup, ordering, and DB
-side effects.
-
-### C. Policy, routing, cost, and runtime control
-
-Known ownership pairs include:
-
-- `lib/policy_store.sh` / `mini_ork.stores.policy_store`
-- `lib/decision_service.sh` / `mini_ork.steering.decision_service`
-- `lib/config_resolve.sh` / `mini_ork.dispatch.config_resolve`
-- `lib/lane-helpers.sh` / `mini_ork.dispatch.lane_helpers`
-- `lib/pricing_strategy.sh` / `mini_ork.dispatch.pricing_strategy`
-- `lib/cost_pause.sh` / `mini_ork.dispatch.cost_pause`

-- `lib/scaffold_tier.sh` / `mini_ork.orchestration.scaffold_tier`
-- `lib/active_state_index.sh` / `mini_ork.orchestration.active_state_index`
-
-Additional live dependencies include `lib/lane_router.sh`,
-`lib/process_reward.sh`, the shared-brain smoke test, executor routing, and
-provider dispatch.
-
-Preserve lane selection, capability assertions, per-run config precedence,
-cost circuit behavior, retry classification, process-reward inputs, and
-operator overrides. Do not replace intentional provider/Git subprocess
-boundaries merely to eliminate Bash.
-
-### D. Steering, context roles, and operator intervention
-
-Known ownership pairs include:
-
-- `lib/context_role_packs.sh` / `mini_ork.steering.context_role_packs`
-- `lib/operator_steering.sh` / `mini_ork.steering.operator_steering`

-- `lib/mid_node_injector.sh` / `mini_ork.steering.mid_node_injector`
-- `lib/mo_node_events.sh` / `mini_ork.observability.node_events`
-
-Current shell callers include `bin/_worker-launcher.sh`, role-pack smoke tests,
-and operator-steering fixtures. Context assembler itself is already native; do
-not reopen that completed fork.
-
-Preserve role-pack precedence, ContextNest-down behavior, empty-result
-fallbacks, bounded payloads, opt-out controls, checkpoint idempotency, and
-stdout/stderr discipline.
-
-### E. Lifecycle, recovery, orchestration, and coordination
-
-Known ownership pairs include:
-
-- `lib/checkpoint.sh` / `mini_ork.stores.checkpoint`
-- `lib/finalize.sh` / `mini_ork.recovery.finalize`
-- `lib/recursive_orchestration.sh` /
-  `mini_ork.orchestration.recursive`
-- `lib/epic_graph.sh` / `mini_ork.orchestration.epic_graph`
-- `lib/coord_registry.sh` / `mini_ork.registries.coord_registry`
-- `lib/coord_gate.sh` / `mini_ork.gates.coord_gate`
-- `lib/branch_quarantine.sh` / `mini_ork.vcs.branch_quarantine`
-- `lib/repo_integrity_guard.sh` / `mini_ork.vcs.repo_integrity_guard`
-- `lib/safety_events.sh` / `mini_ork.stores.safety_events`
-- `lib/auto-merge.sh` / `mini_ork.vcs.auto_merge`
-- `lib/auto-merge-pr.sh` / `mini_ork.vcs.auto_merge_pr`
-- `lib/pr-create.sh` / `mini_ork.vcs.pr_create`
-
-`lib/finalize.sh` sources auto-merge and PR creation, so treat that set as one
-dependency graph. Coordination tests source both registry and gate libraries;
-migrate them together when their contracts cannot be isolated.
-
-Preserve checkpoint durability, resume semantics, rollback/quarantine status,
-branch safety, cascade ordering, pause/budget exits, and public CLI exit codes.
-
-### F. Artifacts, contracts, observability, and persistence
-
-Known ownership pairs include:
-
-- `lib/artifact_contract.sh` / `mini_ork.gates.artifact_contract`
-- `lib/harness_wrapper.sh` / `mini_ork.orchestration.harness_wrapper`
-- `lib/mo_otel.sh` / `mini_ork.observability.otel`
-- `lib/db_open.sh` / `mini_ork.stores.db_open`
-- `lib/memory.sh` / `mini_ork.memory.store`
-- `lib/pattern_store.sh` / `mini_ork.stores.pattern_store`
-- `lib/anchor_corpus.sh` / `mini_ork.stores.anchor_corpus`
-- `lib/bug_report.sh` / `mini_ork.observability.bug_report`
-
-Preserve artifact path security, schema-adaptive inserts, hashes and byte
-counts, compression/retention behavior, WAL/busy-timeout semantics, trace and
-span propagation, contract validation, and missing-table best-effort behavior.
-
-Do not commit databases, transcripts, run directories, or generated evidence.
-
-### G. Learning, evaluation, evolution, and promotion
-
-Known ownership pairs include:
-
-- `lib/benchmark_suite.sh` / `mini_ork.learning.benchmark_suite`
-- `lib/utility_function.sh` / `mini_ork.learning.utility_function`
-- `lib/version_registry.sh` / `mini_ork.registries.version_registry`
-- `lib/group_evolver.sh` / `mini_ork.learning.group_evolver`
-- `lib/role_evolver.sh` / `mini_ork.learning.role_evolver`
-- `lib/cross_epic_gradient.sh` / `mini_ork.learning.cross_epic_gradient`
-- `lib/blame_attributor.sh` / `mini_ork.observability.blame_attributor`

-- `lib/topology.sh` / `mini_ork.orchestration.topology`
-- `lib/topology_metrics.sh` / `mini_ork.observability.topology_metrics`
-- `lib/verifier_rubric.sh` / `mini_ork.gates.verifier_rubric`
-- `lib/rubric-prescreen.sh` / `mini_ork.gates.rubric_prescreen`
-
-The benchmark, utility, promotion, and version-registry tests form a coupled
-E2E cluster. Preserve candidate status transitions, baseline selection,
-utility math, promotion/quarantine outcomes, reward attribution, topology
-metrics, and deterministic benchmark summaries.
-
-Reflection and gradient extraction are already closed. This workstream covers
-their remaining downstream consumers, not the retired reflection libraries.
-
-### H. Agents, roles, healing, cleanup, and supporting libraries
-
-Known ownership pairs include:
-
-- `lib/agent_registry.sh` / `mini_ork.registries.agent_registry`
-- `lib/healer.sh` / `mini_ork.recovery.healer`
-- `lib/mo-healer-bridge.sh` / `mini_ork.recovery.healer_bridge`
-- `lib/cleaner.sh` / `mini_ork.recovery.cleaner`
-- `lib/recovery_planner.sh` or other live recovery surfaces mapped to their
-  native owners
-
-Refresh the inventory for exact names and callers. Preserve registry status,
-performance aggregates, healer proposal boundaries, cleanup allowlists,
-rollback behavior, and external-command safety.
-
-### I. Bash integration, E2E, live, smoke, security, and benchmark fixtures
-
-Fixture conversion is a first-class workstream, not cleanup after runtime
-migration. Current live examples include:
-
-- `tests/e2e/test_e2e_benchmark_run.sh`
-- `tests/e2e/test_e2e_promotion_gate.sh`
-- `tests/e2e/test_e2e_version_registry_rollback.sh`
-- `tests/e2e/test_e2e_workflow_candidate_proposal.sh`
-- `tests/e2e/test_e2e_reflection_pipeline.sh`
-- `tests/integration/test_coord_gate.sh`
-- `tests/integration/test_oracle_gates_auto_wire.sh`
-- `tests/integration/test_autonomous_epic_pipeline.sh`
-- `tests/live/phase_e_live_validation.sh`
-- role-pack, ContextNest, and shared-brain smoke scripts
-- performance and duration fixtures
-
-Convert a fixture only when its protected behavior is preserved. Delete
-fixtures made obsolete by an exact retired owner; retain intentional public CLI
-and external-adapter probes.
-
-### J. Dormant, duplicated, dead, and external-adapter decisions
-
-Every `mini_ork/ported/*.py` module must finish with one decision:
-
-- **integrate** into the canonical Python runtime;
-- **retain** as an intentional boundary with a named owner;
-- **delete** only after all deletion gates pass;
-- **defer** with a documented evidence gap and owner.
-
-No-reference scans alone do not authorize deletion. Check product docs, Git
-history, dynamic path construction, tests, fixtures, benchmarks, schemas, and
-operator contracts.
-
-## Required inventory artifacts
-
-Generate these under a temporary run directory; never commit them:
-
-- `ported-module-inventory.json`
-- `ownership-map.json`
-- `history-intent.md`
-- `proposed-queue.json`
-- `pre-change-contract.json`
-- `verification.json`
-- `requirements-audit-1.md`
-- `requirements-audit-2.md`
-- `verdict.json`
-
-The inventory must cover every current `mini_ork/ported/*.py` module and every
-remaining matching Bash owner, plus unmatched Bash libraries that still sit on
-supported runtime paths.
-
-## Provider and agent policy
-
-Allowed agentic lanes:
-
-- Kimi: broad discovery and history synthesis;
-- Codex: implementation and focused repair;
-- GLM 5.2: independent ownership review and final verdict;
-- deterministic scripts: all pass/fail gates.
-
-Forbidden: MiniMax, DeepSeek, Opus, and implicit provider fallback.
-
-Credentials are process-local only and loaded from the operator scripts under
-`~/ps/scripts`. Never print, copy, commit, or persist credential values.
-
-The checked-in `self-migrate` recipe may still name obsolete lane aliases. Use
-a temporary `MINI_ORK_HOME` with an approved lane map, or run the recipe in
-dry-run mode until its lane configuration is proven compliant.
-
-## Per-unit implementation protocol
-
-1. Fetch `origin/main` and create a fresh isolated worktree.
-2. Run `bin/mini-ork validate` before editing.
-3. Refresh callers, sources, dynamic references, tests, fixtures, benchmarks,
-   docs, and Git history for the selected seam.
-4. Capture deterministic pre-change behavior while the Bash oracle exists.
-5. Implement or adopt one canonical Python owner.
-6. Rewire every in-scope runtime caller.
-7. Replace Bash-oracle tests with standalone golden/native tests.
-8. Run focused unit, integration/E2E/security, and Pyright checks.
-9. Run ownership, duplicate, retirement, secret, and OSS-scope scans.
-10. Perform requirements audit 1 against the task file and relevant `docs/`.
-11. Repair gaps, then perform requirements audit 2 independently.
-12. Commit explicit paths only, merge to clean `main`, push, and prove the
-    commit is on `origin/main`.
-13. Refresh the global inventory before choosing the next unit.
-
-If an audit finds an unresolved requirement, create
-`docs/todos/<timestamp>-<unit>.md` with status, last-worked time, remaining
-parts, evidence, and suggested implementation. Requeue the unit; do not waive
-the requirement.
-
-## Validation matrix
-
-### Every unit
-
-```bash
-python3 -m pytest <focused-test-paths> -q -p no:cacheprovider
-python3 -m pyright <changed-python-modules>
-bin/mini-ork validate
-bin/mini-ork garden
-git diff --check
-git status --short
-```
-
-Also run the affected integration/E2E/security/benchmark probe. A pure
-deterministic unit does not need a paid provider call.
-
-### Provider or LLM-boundary units
-
-After deterministic stubs pass, run one bounded real probe through the public
-path with Codex, Kimi, or GLM as appropriate. Record only redacted evidence.
-No MiniMax request is permitted.
-
-### Entry point or library retirement
-
-Run a zero-reference scan before and after deletion:
-
-```bash
-rg -n '<retired-name>|source .*<retired-name>|\. .*<retired-name>' \
-  bin lib mini_ork gates recipes scripts tests config docs
-```
-
-Classify historical documentation separately from executable/runtime/test
-edges. Any surviving executable edge fails closure.
-
-### Final whole-program gate
-
-```bash
-python3 -m pytest -q -p no:cacheprovider
-python3 -m pyright mini_ork
-bin/mini-ork validate
-bin/mini-ork garden
-git diff --check
-```
-
-Then regenerate the full ownership inventory and prove:
-
-- every ported module has a terminal decision and owner;
-- no useful implementation is orphaned;
-- no supported behavior has multiple canonical implementations;
-- every retired Bash file has zero executable, test, fixture, and benchmark
-  dependency;
-- all explicitly retained Bash boundaries have written rationale and owner.
-
-## OSS-readiness gate
-
-Before every commit and again before final completion:
-
-- inspect the complete diff;
-- scan for credential values, tokens, private endpoints/IPs, personal paths,
-  local provider configs, run IDs with sensitive data, and proprietary assets;
-- exclude `.mini-ork/`, state databases, run artifacts, generated inventories,
-  transcripts, logs, caches, temporary homes, and unrelated files;
-- preserve license headers and public documentation accuracy;
-- stage with explicit pathspecs only.
-
-## Merge and push protocol
-
-```bash
-git status --short
-git diff --check
-git add <explicit owned files>
-git commit -m '<conventional commit message>'
-
-cd /Volumes/docker-ssd/ps/mini-ork-frc
-git fetch origin main
-git merge --ff-only <unit-branch>
-<rerun focused checks on merged main>
-git push origin main
-test "$(git rev-parse main)" = "$(git rev-parse origin/main)"
-git merge-base --is-ancestor <unit-commit> origin/main
-```
-
-If fast-forward is impossible, rebase or recreate the unit from fresh
-`origin/main` in isolation. Never force-push, reset shared history, or merge
-unrelated user-owned changes.
-
-## Stop conditions
-
-Stop and defer the current unit when:
-
-- current product intent cannot be reconstructed;
-- a unique Bash behavior lacks a native owner;
-- deterministic validation fails;
-- a real-provider probe is required but approved credentials are unavailable;
-- the diff contains unrelated or non-OSS-ready files;
-- a clean merge to current `origin/main` cannot be achieved safely.
-
-The overall migration does **not** stop merely because one unit is deferred.
-Document the blocker, keep the Bash owner, refresh the queue, and continue with
-another dependency-safe unit.
-
-## Completion definition
-
-The whole migration is finished only when all of the following are true:
-
-- every current ported module and remaining Bash runtime library has a named
-  owner and terminal decision;
-- dispatcher/provider/telemetry/tool-grant closure is complete;
-- gate and safety libraries are native or intentionally retained;
-- policy, routing, cost, and runtime-control libraries are closed;
-- steering, role, lifecycle, recovery, coordination, and artifact libraries
-  are closed;
-- learning/evaluation/promotion libraries and their E2E fixtures are closed;
-- Bash integration/E2E/security/benchmark blockers are converted or retained
-  with explicit external-boundary rationale;
-- final global tests, Pyright, validate, garden, closure scans, requirements
-  audits, and OSS-readiness checks pass;
-- local `main` equals `origin/main`, and every unit commit is an ancestor of
-  `origin/main`.
-
-Queue exhaustion is not proof. The refreshed final inventory and global
-closure scan are the independent evidence of completion.
-
-## Ready-to-assign instruction
-
-Assign the next agent this document and instruct it:
-
-> Continue autonomously from current `origin/main`. Refresh the complete
-> ownership inventory, select the next dependency-safe ownership seam, use
-> mini-ork validation, preserve old behavior before retirement, commit only
-> OSS-ready migration files, merge each passing unit into clean `main`, push,
-> verify the remote commit, refresh the inventory, and continue until the
-> completion definition in this handoff is satisfied or every safe remaining
-> unit is explicitly deferred with evidence.

-# Remaining bash→Python Migration — Agent Handoff Document
-
-## Lower-level port ownership plan
-
-Before retiring more lower-level libraries, run the report-only inventory in
-`docs/migration/ported-module-ownership-recursive-plan.md`. It closes the gap
-between "a Python port exists" and "the supported runtime owns and uses that
-port," and defines safe `integrate`, `retain`, `delete`, and `defer` outcomes.
-The execution kickoff is
-`kickoffs/migration/ported-module-ownership.md`; its first unit is the duplicated
-similarity implementation in the context assembler.
-
-The Phase 0 inventory completed on 2026-07-20 at `c7ccc512`: all 126 ported
-modules were covered, no deletion was authorized, and the report-only verifier
-passed 38/38 checks after Kimi synthesis and GLM 5.2 review. The first bounded
-unit then moved pure ranking to `mini_ork/similarity.py` and rewired the context
-assembler to its raw-score API while preserving database access, the `0.15`
-threshold, top-three-per-source policy, lesson shape, raw ordering, and
-missing-table behavior. Its focused suite passed 30 tests, Pyright was clean,
-and GLM 5.2 required no repairs.
-
-The next inventory-selected unit closed the first remaining `llm-dispatch`
-caller: `bin/mini-ork-invoke-prompt` is now a thin Python launcher and
-`mini_ork.cli.invoke_prompt` calls
-`mini_ork.dispatch.llm_dispatch` in-process. Its provider boundary remains
-injectable; combined stdout/stderr ordering, environment overlays,
-placeholder substitution, role-pack injection, trace writes, and exit behavior
-have standalone golden-contract coverage. The tests deliberately run without
-`lib/llm-dispatch.sh`, proving that this caller no longer owns a Bash edge.
-The three BDD-first recipe callers now pass the documented
-`MINI_ORK_PROMPT_FILE` variable instead of the stale `MINI_ORK_PROMPT` name.
-The focused invoke/dispatcher suite passed 19 tests, focused Pyright reported
-zero errors, and the unchanged public executable completed a real GLM 5.2
-prompt through a run-local provider registry. Kimi's configured model codes
-were rejected by its gateway, so they were not counted as migration evidence;
-no MiniMax provider was used. The BDD-first dry-run E2E passed 18 assertions,
-`mini-ork validate` passed, and `mini-ork garden` reported zero errors with the
-same missing operator env-var-document warning reproduced on unchanged main.
-Do not retire the dispatcher library yet: the later profile-answerer and
-comparative-opinions units closed two callers, but pre-push review, reflection/
-gradient paths, and Bash fixtures still depend on it. Refresh the inventory
-from the promoted main before selecting the next caller.
-
-The subsequent caller unit made `mini_ork.steering.profile_answerer` native on
-its standalone/default path as well as its already-native planner path. A
-follow-up ownership audit found that the supported Bash implementation had
-already moved to Kimi-only dispatch in `00176709`, while the first native port
-had accidentally restored an older DeepSeek-first default. The retirement unit
-corrected the native owner to two Kimi attempts, preserving retry-on-failure-or-
-whitespace behavior, stdout isolation, and the injectable provider boundary.
-It converted the live Bash-oracle suite to standalone golden contracts,
-rewired the web smoke assertion, and removed `lib/profile_answerer.sh`. The
-planner remains the only production inbound caller and already imports the
-native module directly. This fork is now closed; refresh from promoted main
-before selecting the next caller.
-
-The next caller unit removed `mini_ork/pre_push_review.py`'s Bash dispatcher
-edge. Its sequential panel now calls native `mo_llm_dispatch` in-process while
-preserving configured panel order, Gemini exclusion, per-lens timeout and
-four-turn cap, fail-open behavior, prose-wrapped JSON recovery, issue limits,
-and normalization. Five focused tests and focused Pyright passed, including a
-fixture that proves the panel works without `lib/llm-dispatch.sh`; a real
-single-lens GLM 5.2 probe returned a valid result. No MiniMax request ran.
-`bin/mini-ork-review` and `lib/pre_push_review.sh` remain a separate
-entrypoint/library fork below the frontier and still block dispatcher
-retirement. Refresh promoted main before selecting the next caller.
-
-That review-entrypoint fork is now closed. The CLI-complete runtime and the
-newer native-panel implementation were consolidated into
-`mini_ork.pre_push_review`; `bin/mini-ork-review` is a thin Python launcher,
-and both `lib/pre_push_review.sh` and the duplicate
-`mini_ork.ported.mini_ork_review` owner are retired. The native panel defaults
-to Codex, Kimi, and GLM only. Standalone contracts preserve syntax/secret
-findings, clean approval, verdict policy, list/show/verdict CLI output,
-newline-safe bug forwarding, long-diff handling, and LLM normalization. The
-focused review/meta suite passed 27 tests, focused Pyright reported zero
-errors, and a real public-CLI review persisted a finalized `approve` verdict.
-The ordered repository suite passed 1,838 tests with 28 state-dependent skips
-and one existing Starlette deprecation warning. Validation passed; garden kept
-only the pre-existing missing operator env-var-document warning.
-The remaining dispatcher blockers are lower-level provider/telemetry/tool-grant
-fixtures rather than the review runtime. Refresh promoted main before retiring
-any part of `lib/llm-dispatch.sh`.
-
-The next direct caller unit rewired `scripts/comparative-opinions.sh` from
-sourcing `lib/llm-dispatch.sh` to invoking
-`python3 -m mini_ork.dispatch.llm_dispatch`. The ten-lens background fan-out,
-per-lens files, failure markers, manifest, and summary remain Bash-owned. A
-deterministic acceptance test exercised all ten default calls without a Bash
-dispatcher library. A real script-level probe narrowed the panel to two
-`glm_current` lenses, used minimal temporary input documents, produced two
-substantive opinions and a valid manifest, and made no MiniMax request. The
-historical five-family and canonical-document defaults remain unchanged;
-environment overrides only make bounded validation and operator-selected runs
-possible. Refresh promoted main before continuing to the Bash library forks.
-
-The scheduler integration fork consolidated three owners into one. The public
-`bin/mini-ork-scheduler` path is now a direct Python launcher for
-`mini_ork.scheduler`, the implementation selected by the migration tracker
-because it contains the bounded concurrent pool (`MO_SCHED_MAX_PARALLEL`). The
-serial duplicate `mini_ork.ported.mini_ork_scheduler` and the legacy Bash body
-were removed. Conductor and autonomous-pipeline callers retain the stable
-public executable; generated verification commands now compile it as Python.
-Fourteen standalone contracts cover priority inheritance, deterministic order,
-kickoff/verdict/cascade behavior, budget and pause exits, CLI errors, dry-run
-output/status safety, and public-main concurrency. The autonomous epic pipeline
-passed 13 assertions, focused Pyright was clean, validation passed, and garden
-retained only the pre-existing operator env-var-document warning. The broad
-runtime-parity harness still has unrelated legacy conductor/init failures that
-reproduce with `MINI_ORK_RUNTIME=bash`; they are not scheduler regressions.
-
-The next reflection/gradient unit closed the silent no-op in the supported
-Python path. `mini_ork.learning.gradient_extractor` now builds the established
-recipe-improvement prompt, calls `mini_ork.dispatch.llm_dispatch` in process,
-preserves telemetry/cost controls and the Codex default lane, and recovers
-complete, fenced, prose-wrapped, or truncated JSON arrays with evidence and
-confidence defaults. `mini_ork.learning.reflection_pipeline` now uses native
-extract/store/schema helpers unless a deterministic override is injected.
-Twenty-nine focused gradient/reflection/reflect tests passed, Pyright was clean,
-and an evidence-rich failed verifier trace produced three valid gradients via a
-real GLM 5.2 request. No MiniMax or DeepSeek request ran. Validation passed and
-garden retained only the pre-existing operator env-var-document warning. This
-unit makes the production reflection path native; the Bash gradient/reflection
-libraries and their Bash-oracle/E2E tests remain the next retirement fork.
-
-The follow-up reflection contract-closure unit ports the three remaining
-load-bearing behaviors discovered before physical retirement. Native gradient
-helpers now identify framework-internal `__*` task classes and detect the
-per-trace evidence watermark; native reflection excludes internal traces and
-skips already-processed traces before dispatch. Per-node credit reweighting is
-native, transient, gamma-clamped, and restored after routing even when router
-recomputation fails. The public reflect entrypoint now calls
-`mini_ork.lane_router.recompute_advantages` directly instead of sourcing
-`lib/lane_router.sh`. Standalone contracts cover framework filtering,
-watermark idempotency, reward apply/restore/off behavior, and the native router
-side channel. Thirty-three focused Python tests passed, the two legacy contract
-suites passed 23 checks with one environment-dependent routing skip, focused
-Pyright was clean, reflect acceptance and validation passed, and garden kept
-only the pre-existing missing operator env-var-document warning. The next fork
-is still physical retirement: convert the unique
-Bash gradient/reflection integration contracts to standalone Python, remove
-the two Bash libraries, and prove a zero-reference closure scan.
-
-That physical retirement fork is now complete. The live-oracle Python suites
-are standalone native contracts; unique cross-target store dedup, semantic
-trace-noise collapse, distinct-intent preservation, D5 credit restoration, and
-pattern-miner-to-promotion writeback remain covered. The mixed reflection and
-full self-improvement E2Es call the native modules directly without losing
-their still-Bash downstream coverage. Five redundant Bash suites and both
-legacy libraries were removed, and doctor/recursive-migration metadata no
-longer advertises them. The focused native suite passed 35 tests, the two E2Es
-passed 8 and 13 assertions, the remaining router suite passed 2 checks with its
-unchanged environment-dependent D1b skip, and focused Pyright was clean. A
-closure scan finds no executable reference to either retired library; old
-filenames remain only in historical changelog, kickoff, research, and refactor
-records. The repository-wide Python suite passed 1,831 tests with 28 expected
-skips and two unrelated deprecation warnings; reflect acceptance and validation
-also passed, while garden retained the existing missing operator env-var-doc
-warning. Refresh from promoted main and select the next inventory edge; the
-remaining context-assembler surface is the next item in this ownership group.
-
-The context-assembler ownership fork is now closed. The native
-`mini_ork.context_assembler` owns bounded packs, failure/prior-run blocks,
-ContextNest capsule/retrieve and recent-session helpers, operator-steering
-rendering, active-state injection, and a narrow module CLI for the Bash
-fixtures that remain below the frontier. Role-pack fallbacks and the autonomous
-epic/slice/smoke fixtures now call that native CLI; standalone pytest contracts
-replace the Bash oracle, and `lib/context_assembler.sh` plus its redundant Bash
-unit suite are removed. The focused context/role/steering suite passed 40
-tests, the autonomous epic pipeline passed 13 assertions, both slice-provider
-budget regimes completed, focused Pyright reported zero errors, and the
-repository-wide suite passed 1,850 tests with 13 expected skips and two
-unrelated deprecation warnings. Validation passed; garden retained only the
-pre-existing missing operator env-var-document warning. The rewired CN bridge
-and capsule-swap smokes passed 8 and 6 assertions, and the 13 MB oversized-input
-security test passed all 6 checks. The live role-pack smoke passed 7 of 8
-assertions because the current ContextNest corpus returned no reviewer slice;
-unchanged main produced the same result, while both CN-down contracts passed.
-A zero-reference executable scan is required at every future refresh;
-historical filenames remain in kickoff, changelog, research, and refactor
-records only. Continue from promoted main with the refreshed lower-level
-ownership inventory.
-
-## Context
-
-The self-migrate recipe (PR #184, merged at commit 6bf438a) implements integration-point-first migration: close ONE fork (bash↔Python seam) at a time as a complete unit — make Python sole, repoint every inbound reference, retire bash entrypoint — gated on byte-parity, feature-acceptance, and static-feature ledger.
-
-**This is the recipe you will run.** Do NOT improvise your own approach.
-
-## What "integration fork" means
-
-A fork = bash entrypoint + Python port + every inbound reference.
-
-Migration advances a single frontier root→down:
-- ABOVE the frontier = pure Python
-- BELOW the frontier = pure bash
-- NO half-migrated seams allowed
-
-The fork unit prevents the "leaf migration" anti-pattern where a Python module goes native but the paired bash entrypoint (and every lib/test/UI ref to it) stays live — splitting integration points and leaving half-open seams.
-
-## Integration-point map (blast radius per fork)
-
-| Fork | Outbound seams | Inbound refs | Blast radius |
-|------|---------------|--------------|--------------|
-| **verify** | 0 | 7+ live refs | Cleanest proof case; the original five-ref snapshot omitted the top-level and legacy execute callers |
-| **reflect** | 2 | 8 | Medium |
-| **classify** | 0 | 18 | High inbound, no outbound |
-| **plan** | 1 | 25+ | High inbound; native dispatcher plus profile/context/trace contracts had to close together |
-| **execute** | 4 | 37 | Monster: 4 outbound, 37 inbound |
-| **cli** | 3 (dispatcher-level) | — | Critical path |
-
-Source: `docs/migration/self-migrate-feature-manifest.md` §"Integration-point map"
-
-## Recommended migration order
-
-**verify → reflect → classify → plan → cli → execute**
-
-Why this order:
-- **verify** first: cleanest (0 outbound, 7+ inbound), validates the whole recipe pipeline
-- **reflect** second: medium blast, 2 outbound seams
-- **classify/plan**: high inbound but NO outbound (Python already runtime-native)
-- **cli** before **execute**: dispatcher-level, affects everything below
-- **execute** last: the monster (4 outbound + 37 inbound, includes context_assembler 786L)
-
-## How to run the self-migrate recipe
-
-### Step 1: Pick a fork
-
-Example: verify fork (the proof case):
-
-```bash
-export MINI_ORK_ROOT="$PWD"
-export MINI_ORK_HOME="$PWD/.mini-ork"
-export MO_TARGET_CWD="$PWD"
-export MO_ALLOW_FRAMEWORK_CWD=1  # self-edit permission
-export MO_FORK=verify             # name the fork
-
-"$MINI_ORK_ROOT/bin/mini-ork" run self-migrate recipes/self-migrate/example-kickoff.md
-```
-
-`MINI_ORK_ROOT` is the engine checkout; `MINI_ORK_HOME` is runtime state. The
-older `$PWD/.mini-ork/bin/mini-ork` form is invalid in a scaffolded checkout
-because `.mini-ork/engine` is a pointer, not a second engine tree.
-
-For other forks, create a kickoff modeled after `recipes/self-migrate/example-kickoff.md`:
-- Set `fork: <fork-name>`
-- Set `python entrypoint: /abs/path/to/mini_ork_<fork>.py`
-- Set `bash entrypoint to retire: /abs/path/to/bin/mini-ork-<fork>`
-- List all inbound refs from the integration map
-
-### Step 2: The recipe pipeline
-
-1. **seam_mapper (GLM)** → `integration-map.json`
-   - Every outbound seam (Python→bash shell-out)
-   - Every inbound reference (bin/, lib/, mini_ork/, tests/, scripts/, web UI)
-   - Runtime-select coupling
-   - Close blockers
-
-2. **static_feature_ledger (GLM)** → `static-feature-ledger.json`
-   - Classify EVERY behavior in the Python module:
-     - **static**: deterministic, ~0 tokens, byte-parity verifiable (the moat)
-     - **agentic**: LLM call, expensive, weakly verifiable
-     - **integration**: bash↔Python seam (temporary, should disappear)
-   - Agentic rows MUST carry `opportunity`: cost-down analysis
-   - This ledger IS mini-ork's cost/verifiability map — the strategic payload
-
-3. **migrator (codex)** → `self-migrate.diff`
-   - Make Python sole (AST-verify port is runtime-native FIRST)
-   - Repoint EVERY inbound reference to Python module
-   - Retire bash entrypoint in the diff
-   - Stdout discipline: wrap printing ports in `redirect_stdout`
-
-4. **verify** (5 gates)
-   - `pre-retirement-parity.sh`: captures the live bash oracle before any retirement edit
-   - `parity.sh`: focused fork parity / Python golden contract
-   - `feature-acceptance.sh`: end-to-end feature probe
-   - `ledger-shape.sh`: ledger completeness (every feature has a row, agentic rows have opportunity)
-   - `fork-closure.sh`: physical entrypoint removal plus literal and dynamic caller scans
-
-5. **reviewer (GLM)** → `verdict.json`
-   - `pass == parity_pass && acceptance_pass && ledger_complete && no_dangling_edge`
-
-### Step 3: Verdict → apply or rollback
-
-If `verdict.json` says `"pass": true`:
-- Review `self-migrate.diff` for sanity
-- Apply the diff: `git apply self-migrate.diff`
-- Run feature-acceptance again: `bash gates/feature_acceptance.sh <fork>`
-- If all green, commit and move to next fork
-
-If `verdict.json` says `"pass": false`:
-- Read the `reasons` array in verdict.json
-- Fix the issue (re-run migrator, or fix the Python port, or fix a verifier)
-- Re-run the recipe
-
-## Lane policy for the remaining forks
-
-Set in `$MINI_ORK_HOME/config/agents.yaml`:
-
-| role | lane | backoff |
-|---|---|---|
-| implementer (`migrator`) | **codex** | codex |
-| planner / general research | **Kimi** (`kimi_current`) | codex |
-| mapper / ledger / reviewer | **GLM 5.2** (`glm_current`) | codex |
-
-**WHY this policy:**
-- Codex is the implementer lane (writing code, not analysis)
-- Kimi provides planning and broad discovery through the authenticated coding API
-- GLM 5.2 owns seam analysis, ledger judgment, and review
-- MiniMax and Opus are not provider values for the remaining migration runs
-
-Use a dedicated temporary `MINI_ORK_HOME` rather than editing the user's
-`.mini-ork/config/agents.yaml`. Load Kimi and GLM credentials process-locally
-from `/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`; never persist their
-values in repository files or run artifacts. The local Kimi Claude wrapper's
-hard-coded model is stale, so the reflect run used a run-local executable
-adapter against the authenticated Anthropic-compatible messages endpoint.
-
-## Feature-acceptance probes
-
-`gates/feature_acceptance.sh <fork|feature>` — end-to-end acceptance suite.
-
-**Feature ↔ entrypoint map**:
-- `classify` / `plan` / `execute` / `verify` / `reflect` → the 6 loop stages
-- `routing` → learning-governed router flips (learning-loop-live-validate)
-- `learning-loop` → reward→routing closure (learning-loop-closure-gate)
-- `verify-gate` → a real cheat is rejected / a real fix passes
-- `framework-edit` → propose-not-commit self-modification
-- `resume` → durable checkpoint resume
-- `epics` → dependency-ordered multi-epic delivery
-
-Run `gates/feature_acceptance.sh all` to probe every feature.
-
-## Known gotchas
-
-### 1. Stdout discipline in Python ports
-
-The migrator (codex) MUST wrap any printing in the Python entrypoint:
-
-```python
-# BEFORE (breaks parity — prints go to stdout, not captured)
-print("warning: missing file")
-
-# AFTER (parity-safe)
-redirect_stdout(lambda: print("warning: missing file"))
-```
-
-Why: parity harness captures stdout for byte-exact comparison. Raw prints leak timing metadata and break parity.
-
-### 2. AST-verify port is runtime-native BEFORE migration
-
-The migrator's first step: verify the Python port is already runtime-native (no outbound shell-outs to bash).
-
-If the Python port still calls `bin/mini-ork-*`, the fork is NOT ready for migration — those are outbound seams that need their own forks closed first.
-
-### 3. Runtime-select coupling
-
-`lib/runtime-select.sh` determines whether bash or Python runs at runtime. Some forks may have runtime-select coupling that needs repointing.
-
-The integration map (`seam_mapper` node) catches this — check `integration-map.json` for `runtime-select` entries.
-
-### 4. No dangling edges
-
-The reviewer checks: grep the diff for ANY surviving reference to `bin/mini-ork-<fork>`.
-
-If ANY ref survives (in tests, lib, scripts, web UI), the fork is NOT closed — verdict is fail.
-
-### 5. Ledger completeness is a deliverable
-
-The static-feature ledger is NOT optional — it's the migration's strategic payload.
-
-`ledger-shape.sh` enforces:
-- Ledger exists at `static-feature-ledger.json`
-- Well-formed JSON
-- Every feature in the module has a row
-- Agentic rows carry `opportunity` (cost-down analysis)
-- Functions changed in the diff have ledger rows (cross-check)
-
-## Files in scope for each fork
-
-### verify fork (example)
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork`
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork-execute`
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/cli/verify.py`
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork-verify`
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/cli/execute.py` (repoint bin/mini-ork-verify invocation)
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/cli/main.py` (direct and run-lifecycle dynamic `_bin(root, "verify")` dispatch)
-- `/Volumes/docker-ssd/ps/mini-ork/tests/e2e/test_e2e_recipe_code_fix.sh`
-- `/Volumes/docker-ssd/ps/mini-ork/tests/integration/test_bin_verify.sh`
-- `/Volumes/docker-ssd/ps/mini-ork/tests/unit/test_mini_ork_verify_py.py`
-- `/Volumes/docker-ssd/ps/mini-ork/lib/runtime-select.sh`
-- `/Volumes/docker-ssd/ps/mini-ork/gates/feature_acceptance.sh`
-- `/Volumes/docker-ssd/ps/mini-ork/scripts/runtime-parity-harness.sh`
-
-### Other forks
-
-Each fork has its own inbound ref surface. The `seam_mapper` node discovers this automatically — you don't need to manually enumerate refs.
-
-**Reference:** `docs/migration/self-migrate-feature-manifest.md` has the full integration-point map with every inbound ref listed per fork.
-
-## Verification checklist BEFORE applying a diff
-
-- [ ] `parity.sh` passed (byte-parity == bash oracle on live state.db)
-- [ ] `feature-acceptance.sh <fork>` passed (end-to-end feature still works)
-- [ ] `ledger-shape.sh` passed (ledger complete, agentic rows have opportunity)
-- [ ] `verdict.json` says `"pass": true`
-- [ ] No surviving `bin/mini-ork-<fork>` refs in diff (grep diff for the pattern)
-- [ ] Reviewed `self-migrate.diff` for sanity (check for deleted files, wrecked imports, etc.)
-
-## After applying the diff
-
-- [ ] Run feature-acceptance again: `bash gates/feature_acceptance.sh <fork>`
-- [ ] Run `gates/feature_acceptance.sh all` to ensure no other features broke
-- [ ] Commit: `git commit -m "feat(migrate): close <fork> fork — Python sole, bash entrypoint retired"`
-- [ ] Move to next fork in recommended order
-
-## Fallback: rollback
-
-If a fork migration goes wrong (parity breaks, feature breaks, or verdict is fail):
-
-1. DO NOT apply the diff
-2. Check `verdict.json` → `reasons` array for what failed
-3. Fix the root cause (Python port bug, verifier false-positive, migrator error)
-4. Re-run the recipe from step 1
-
-The recipe is propose-not-commit — nothing is applied until verdict is pass.
-
-## Strategic payload: the static-feature ledger
-
-Every migration run produces `static-feature-ledger.json`. This is mini-ork's cost/verifiability map:
-
-**Static behaviors** = the moat:
-- Deterministic
-- ~0 token cost
-- Byte-parity verifiable
-- Example: JSON parsing, file I/O, schema queries
-
-**Agentic behaviors** = cost/verifiability liability:
-- LLM call
-- Expensive
-- Weakly verifiable
-- Example: code generation, summarization, open-ended Q&A
-- **Every agentic row MUST carry `opportunity`** — how to reduce cost or improve verifiability
-
-This ledger tells us WHERE to optimize mini-ork itself — the migration's real deliverable, not just the port.
-
-## Deliverable for this migration cycle
-
-Run the self-migrate recipe on each fork in recommended order:
-1. ✅ verify (closed and source-applied from the fully verified isolated Run 3 proposal; see the live evidence below)
-2. ✅ reflect (closed and source-applied from `run-1784503045-70610`; see the live evidence below)
-3. ✅ classify (closed and source-applied from `run-1784528328-42404`; see the live evidence below)
-4. ✅ plan (closed by the completion audit after partial `run-1784532524-76798`; see live evidence below)
-5. ✅ cli (closed, merged, and pushed; see live evidence below)
-6. ✅ execute (closed by the completion audit after the one authorized provider run; see live evidence below)
-
-## Live verify evidence — 2026-07-19
-
-### Run 1: `run-1784474339-7704`
-
-- Result: partial, unapplied.
-- Findings: incomplete scope, composite publisher corruption, incorrect reviewer target resolution, and no deterministic fork-closure gate.
-- Outcome: those recipe/runtime defects were repaired and regression-tested before rerunning.
-
-### Run 2: `run-1784478877-84933`
-
-- Isolated target: `/private/tmp/mini-ork-self-migrate-verify-v2`.
-- Result: `needs_revision` / partial, unapplied; rollback ran and no retirement reached the source checkout.
-- Functional evidence: 11 verify unit tests, 3 executor verifier-node tests, 8 integration assertions, feature acceptance, Pyright, shell syntax, diff hygiene, and both runtime-selector CLI smoke paths passed.
-- Closure blocker: `mini_ork/cli/main.py` still resolves `_bin(root, "verify")` for direct and run-lifecycle dispatch. It was outside the run's allowlist, so the migrator correctly retained `bin/mini-ork-verify`.
-- Review evidence: `review-diff.patch` contains the real isolated-worktree delta and is byte-identical to the restored `self-migrate.diff` (31,513 bytes).
-- Canonical artifacts: `.mini-ork/runs/run-1784478877-84933/` contains the partial diff, complete 52-row feature ledger, detailed `verdict.json`, preserved generic `run-verdict.json`, both requirements reviews, and verifier evidence.
-
-### Repairs after run 2
-
-- Added `mini_ork/cli/main.py` to the corrected verify scope and taught `fork-closure.sh` to detect dynamic `_bin(..., "verify")` dispatch.
-- Made all five recipe verifier exit statuses mirror their JSON `.pass`; a failed closure report can no longer be counted as a successful process gate.
-- Made `ledger-shape.sh` recognize qualified feature names while still requiring a row for every changed public function.
-- Preserved heterogeneous run-local artifacts and the explicit isolated target with focused regression coverage.
-
-### Run 3: `run-1784482847-61479`
-
-- Isolated target: `/private/tmp/mini-ork-self-migrate-verify-v3`.
-- The isolated migration verdict passed: 11 changed files, a complete 33-row ledger, durable pre-retirement evidence, post-retirement parity, feature acceptance, ledger shape, and fork closure all green.
-- The proposal removed `bin/mini-ork-verify`, repointed the top-level shell dispatcher, legacy executor, Python CLI, and Python executor to `python -m mini_ork.cli.verify`, and converted parity tests to standalone golden contracts.
-- The canonical Python verifier now executes command-backed checks once, captures combined stdout/stderr as evidence, and preserves verifier trace telemetry without making observability a failure mode.
-- The generated diff was reviewed, applied to the source checkout, and byte-compared against every file in the verified worktree.
-- Post-apply verification passed: 9 verify tests, 47 executor tests, 6 CLI tests, 8 integration assertions, 18 E2E assertions, focused runtime parity, Pyright across verify/CLI/executor, all five self-migrate gates, and `git diff --check`.
-
-The outer recipe run still ended `partial`/failed after the implementation had
-passed. Its reviewer looked for canonical verifier-report filenames before the
-migrator's sandbox-mirrored artifacts were reconciled into the engine run
-directory, returned `needs_revision`, and triggered rollback. This was an
-orchestration artifact-handoff defect, not a verify-fork defect: the mirrored
-detailed `verdict.json` has `pass: true`, and the source-applied diff passed the
-same gates again.
-
-The handoff defect is now repaired in the source checkout. Self-migrate runs
-harvest the isolated target's allowlisted run artifacts before reviewer
-dispatch, generate an implementer summary from that evidence, and include the
-recipe-specific verifier reports, integration map, feature ledger, detailed
-verdict, and migration diff in reviewer inputs. Generic orchestration status is
-written to `run-verdict.json`, so a recipe-owned detailed `verdict.json` is no
-longer overwritten. Regression tests cover same-run mirror visibility,
-reviewer evidence assembly, and verdict preservation.
-
-### Post-repair verification
-
-- The executor unit module passes all 50 tests, including the three artifact-handoff regressions.
-- Verify and CLI unit modules pass all 15 tests; integration and E2E scripts pass 8 and 18 assertions respectively.
-- Pyright reports zero errors across the migrated verifier, CLI, and executor; `bin/mini-ork validate`, shell syntax checks, and `git diff --check` pass.
-- `bin/mini-ork garden` reports 0 errors and 0 warnings (265 informational stale-run notices only).
-- The repository-wide direct pytest run completed with 1,805 passed, 5 skipped, and 3 source-checkout-state failures: one capability-policy expectation affected by the user-owned `.mini-ork/config/agents.yaml`, plus two reflect opt-out tests. The reflect failures reproduced in the dirty source checkout but all 8 reflect tests pass in the clean isolated migration worktree. The documented `make test` command is unavailable because this checkout has no `test` Make target.
-
-### Reflect launch attempt 1: `run-1784502357-9667`
-
-- The run stopped at planner dispatch before seam mapping or implementation.
-- The frozen run policy selected MiniMax for `planner`, but
-  `MINIMAX_API_KEY` is unset; `mini-ork doctor` reports MiniMax unavailable.
-- No proposal or verdict was produced, and the isolated reflect worktree stayed
-  clean at `0fe5071c`.
-- The safe retry uses a dedicated temporary runtime home with only Kimi,
-  Codex, and GLM provider values. Kimi and GLM credentials are loaded
-  process-locally from `/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`;
-  no secret or persistent user-owned policy is changed.
-
-## Live reflect evidence — 2026-07-20
-
-### Passing proposal: `run-1784503045-70610`
-
-- Isolated target: `/private/tmp/mini-ork-self-migrate-reflect`.
-- Provider policy used only Kimi, Codex, and GLM: Kimi planned, Codex migrated,
-  and GLM 5.2 mapped seams, built the authoritative ledger, and reviewed.
-- The proposal deletes `bin/mini-ork-reflect` and repoints the top-level CLI,
-  legacy executor, Python CLI, Python executor, GEPA wiring, and integration
-  coverage to `python -m mini_ork.cli.reflect`.
-- All five migration reports pass: durable pre-retirement parity,
-  post-retirement parity, feature acceptance, the 27-row static-feature ledger,
-  and deterministic fork closure. The GLM reviewer and detailed
-  `verdict.json` also pass.
-- The preserved proposal and isolated target diff were byte-identical
-  (`sha256: 173793e43fb3d24355b4d0683101c3d9578fa536157ceb7d51ed4efaecfb8f03`)
-  before promotion.
-- Post-apply checks pass: 11 reflect/GEPA tests, 11 integration assertions, 8
-  parity cases, reflect feature acceptance, Pyright, ledger shape, closure,
-  Bash syntax, and diff hygiene.
-
-### Executor repairs discovered by the completion audit
-
-- Reviewer assembly now includes the standalone
-  `pre-retirement-parity.json`, not only `verifier_*.json`, with focused
-  regression coverage.
-- The run's outer `failed_nodes=1` was traced to the generic hollow-artifact
-  guard running on `pre_retirement_parity` before the migrator could create
-  final artifacts. The executor now derives verifier phase from workflow order:
-  baseline verifiers before the first implementer may run, while every later
-  verifier remains fail-closed on missing artifacts.
-- The executor/CLI suite passes all 57 tests after both repairs; Pyright reports
-  zero errors on execute, CLI, and reflect.
-
-### Historical plan preflight
-
-The canonical `kickoffs/migration/plan.md` and clean isolated target
-`/private/tmp/mini-ork-self-migrate-plan` are prepared at the focused
-classify-closure commit `928db915`. Its no-cost baseline passes 9 unit tests,
-17 integration assertions, and plan feature acceptance. Focused Pyright has
-three documented baseline errors that the plan migration had to close. This
-preflight led to `run-1784532524-76798` and the completion audit documented in
-the live plan evidence below.
-
-## Live classify evidence — 2026-07-20
-
-### Passing proposal: `run-1784528328-42404`
-
-- Isolated target: `/private/tmp/mini-ork-self-migrate-classify`.
-- Provider policy used only Kimi, Codex, and GLM: Kimi planned, Codex migrated,
-  and GLM 5.2 mapped seams, built the authoritative ledger, and reviewed.
-- The proposal deletes `bin/mini-ork-classify` and repoints the top-level Bash
-  dispatcher, Python CLI lifecycle, validation, integration, E2E, security,
-  parity-harness, and user-facing references to
-  `python -m mini_ork.cli.classify`.
-- The Python runtime now preserves Bash trace start/success side effects through
-  a best-effort native trace-store call while keeping dry-run side-effect free.
-- All five migration reports pass: durable pre-retirement parity,
-  post-retirement parity, feature acceptance, the 29-row static-feature ledger,
-  and deterministic fork closure. The GLM reviewer and detailed
-  `verdict.json` also pass.
-- Independent replay passed 15 classify/CLI unit tests, 9 classify integration
-  assertions, 16 post-MVP integration assertions, 43 security assertions, 53
-  E2E assertions, feature acceptance, focused Pyright, all post-retirement
-  migration gates, and diff hygiene.
-- The outer command exited non-zero after the passing workflow because the
-  generic Python verifier invokes globally registered oracle gates without
-  their required `recipe`, `verdict_file`, or `current_round` context and then
-  treats `defer` as failure. This was diagnosed without a paid retry and did not
-  invalidate the green fork-specific evidence.
-
-## Live plan evidence — 2026-07-20
-
-### Partial proposal and blocker discovery: `run-1784532524-76798`
-
-- Isolated target: `/private/tmp/mini-ork-self-migrate-plan`, baseline
-  `928db915`.
-- Provider policy used only Kimi, Codex, and GLM: Kimi planned, Codex migrated,
-  and GLM 5.2 mapped seams, built the ledger, and reviewed. MiniMax and DeepSeek
-  gateway variables were unset for the run.
-- The pre-retirement Bash/Python oracle was captured green before Codex edited
-  the target. Post-change parity, feature acceptance, and ledger shape also
-  passed.
-- Codex's second requirements audit found four Bash-owned contracts missing
-  from the original integration map: profile normalization/question handling,
-  planner context injection, context-pack persistence, and planner trace
-  lifecycle writes. It restored `bin/mini-ork-plan`; fork closure failed; GLM
-  correctly rejected the proposal. No paid retry ran.
-
-### Completion audit and closure
-
-- The Python planner now calls the native dispatcher in-process while preserving
-  the injectable `(returncode, combined_output)` contract and merged stream
-  capture.
-- Native profile handling preserves zero-question normalization,
-  non-interactive auto-answering, `/dev/tty` interactive answers, confidence
-  updates, profile answer artifacts, and fail-closed blocking.
-- Native context orchestration preserves learned failure modes, prior runs,
-  the ContextNest planner role pack with generic fallback, recent-file sessions,
-  active-state injection, and the auditable `context-pack.json` artifact.
-- Planner running, blocked, failure, fallback, and success traces use
-  `mini_ork.trace_store`. Migration `0054_execution_traces_status_blocked.sql`
-  fixes the pre-existing schema contradiction that silently rejected the Bash
-  planner's `blocked` status; applying it to a pre-0054 database preserved the
-  existing trace and accepted a blocked trace.
-- Every executable caller and test was repointed to
-  `python3 -m mini_ork.cli.plan`; `bin/mini-ork-plan` was deleted.
-- Independent post-retirement evidence is green: 39 focused planner/context
-  tests, 25 CLI/context tests, 10 plan integration assertions, 7 given-plan
-  assertions, the recursive profile-gate verifier, 5 path-traversal assertions,
-  29 web-smoke passes (25 environment skips), focused Pyright, post-retirement
-  parity, feature acceptance, the 58-row completion ledger, deterministic fork
-  closure, and database-migration preservation.
-- The model-authored detailed verdict remains the honest rejected partial-run
-  record. Promotion is based on the later deterministic five-gate evidence plus
-  two source-requirements audits; the rejected verdict was not rewritten and no
-  paid reviewer replay was hidden.
-
-### CLI closure — 2026-07-20
-
-- The isolated `migration/cli` implementation was completed after three
-  requirements audits, promoted to `main`, and pushed.
-- `bin/mini-ork` remains the executable public path but is now a thin Python
-  launcher. It resolves symlinks, imports `mini_ork_cli.main`, and never reads
-  `MINI_ORK_RUNTIME` or sources `runtime-select.sh`.
-- Direct `classify`, `plan`, `verify`, and `reflect` commands route to native
-  Python modules. The missing `apply` dispatch was restored; execute was then
-  closed as the final top-level fork.
-- Deadline state, per-run config snapshots, repository healing, rubric
-  scoring, and reward grading use native Python ports with their prior
-  best-effort or return-code contracts preserved.
-- The public-path inbound callers remain unchanged because the path, executable
-  bit, argv, stdout/stderr, and exit-code contracts remain stable. A stale web
-  line-number comment was updated.
-- A third audit found that the original parity helper did not force
-  `MINI_ORK_RUNTIME=bash` and could therefore compare Python with Python. The
-  untouched pushed-main dispatcher was rerun in explicit Bash mode: all 40
-  legacy dispatcher assertions passed, and exact version/help/doctor/error
-  parity now passes against the Python launcher. The corrected evidence also
-  drove native `lib/paths.sh`-equivalent environment and engine-pointer
-  resolution into the launcher.
-- Evidence is green: the durable pre-retirement oracle, 8 standalone CLI tests,
-  46 dispatcher assertions, focused Pyright, post-retirement parity, feature
-  acceptance, the 48-row completion ledger, deterministic CLI closure, diff
-  hygiene, and three requirements audits.
-
-### Execute closure — 2026-07-20
-
-- Exactly one authorized paid run used Kimi, Codex, and GLM. Its model-authored
-  review returned `needs_revision`; no paid retry was made. The completion
-  audit repaired the PRM, minimal-scaffold, resolved-model routing, and plan
-  task-class gaps deterministically.
-- `mini_ork/cli/execute.py` owns the complete executor lifecycle,
-  including bounded process-isolated concurrency. Direct `execute` and the
-  full run lifecycle route to it in-process.
-- Dispatch, capability checks, learned context, operator steering,
-  intervention gating, gate bootstrap, and liveness are native. Provider,
-  git, and executable verifier calls remain explicit external boundaries.
-- Every executable inbound edge is repointed and `bin/mini-ork-execute` is
-  deleted. Durable pre-retirement evidence replaces the old live-Bash parity
-  dependency.
-- Final evidence is green: 57 execute tests, 11 dispatcher tests, 88 adjacent
-  native-port/CLI tests, 10 execute integration assertions, broad E2E and
-  recursive integration, a non-zero duration trace, isolated observability,
-  focused Pyright, the 76-row ledger, and all five self-migrate gates.
-- Two requirements audits found no remaining execute-fork requirement. Secret
-  and scope checks exclude credential values, local adapters, runtime state,
-  logs, and the user's `.mini-ork/config/agents.yaml`.
-
-### Migration-cycle result
-
-All six top-level task-loop forks are closed. Future work in the completion
-plan concerns lower-level Bash libraries, scheduler/utility entrypoints, and
-historical fixture retirement; it is not an open execute-fork requirement.
-
-Each fork closure produces:
-- `self-migrate.diff` (reviewable, apply or reject)
-- `static-feature-ledger.json` (cost/verifiability map)
-- `integration-map.json` (blast radius documentation)
-- `verdict.json` (pass/fail with reasons)
-
-**Final state for this cycle:** the public task loop and all six named forks are
-Python-owned. Remaining lower-level Bash units stay tracked in
-`docs/migration/python-migration-completion-plan.md` rather than being folded
-into this execute commit.
-
-## Historical verify execution findings (2026-07-19)
-
-The first isolated verify run is preserved at
-`.mini-ork/runs/run-1784474339-7704`. Its three original recipe verifiers
-passed, but the reviewer correctly returned `partial` and rollback fired.
-Nothing from the proposed fork diff was applied to the source checkout.
-
-The run exposed five contract gaps:
-
-1. `bin/mini-ork` and `bin/mini-ork-execute` are live verifier callers but were
-   absent from the original five-reference kickoff scope.
-2. The generic publisher copied `self-migrate.diff` over the JSON ledger and
-   verdict; it now preserves heterogeneous run-local artifacts byte-for-byte.
-3. No deterministic gate proved that the entrypoint and runtime references
-   were gone; `verifiers/fork-closure.sh` now supplies that gate.
-4. The global parity harness has five pre-existing divergences (`help`,
-   `doctor`, `conductor --help`, `execute --help`, and `init`). Those are tracked
-   separately rather than blocking this one-fork migration. The verify fork's
-   own 9-scenario parity suite is the retirement oracle, and the recipe now
-   captures it before the migrator can remove the Bash entrypoint.
-5. Target resolution derived `/private/tmp` from the temporary kickoff path and
-   hid the real worktree diff from the reviewer. A valid explicit
-   `MO_TARGET_CWD` now wins over kickoff-location inference.
-6. The second run found a dynamic caller in `mini_ork/cli/main.py`:
-   `_bin(root, "verify")`. The canonical kickoff now scopes that file and the
-   closure gate checks dynamic resolver calls as well as literal paths.
-7. The third run closed and source-applied the verify fork, but its outer
-   reviewer ran before sandbox-mirrored reports were reconciled. The runtime now
-   harvests the allowlisted target-run mirror before reviewer dispatch, keeps
-   detailed and generic verdicts separate, and regression-tests reviewer input
-   assembly. The reflect run subsequently confirmed the artifact-handoff
-   contract and closed the final standalone-report omission.
-
-The detailed first-audit backlog is
-`docs/todos/20260719-174802-remaining-migration-first-audit.md`.
-
-## Handoff
-
-You now have everything you need:
-- The recipe: `recipes/self-migrate/`
-- The example kickoff: `recipes/self-migrate/example-kickoff.md`
-- The feature manifest: `docs/migration/self-migrate-feature-manifest.md`
-- The lane policy: §"Lane policy" above
-- The verification checklist: §"Verification checklist" above
-
-Run the recipe. Do NOT improvise. The recipe encodes the hard-won lessons from the verify fork proof case.
-
-**GO.**

-# Self-migration: the core-feature manifest + acceptance probes
-
-_Written 2026-07-18. Defines what "the bash→Python migration is done **correctly**" means:
-not "unit tests pass" but "**every feature mini-ork promises still works end-to-end**."_
-
-## Why this document exists first
-
-The migration's unit-level oracle is perfect and free: `bash_fn(real.db)` vs `native_fn(real.db)`,
-byte-for-byte. But unit-parity is **necessary, not sufficient**. This session's cross_epic rewire
-passed unit-parity yet leaked a stray `0` into reflect's stdout — only the *end-to-end* reflect
-probe caught it. So the migration's real finish line is a **feature-acceptance suite**: one
-replayable probe per promised feature, run as the migration recipe's final gate. This doc is that
-suite's specification. Everything else (the recipe, the observe→improve loop) gates on getting
-this list right — hence it comes first, for sanity-check.
-
-## The competitive advantage this protects
-
-mini-ork's moat is **verification** — nothing ships unless the verify-gate says so. The migration
-is the ideal proving ground because the bash lib is an un-gameable oracle. But the *thing being
-protected* is the promise that a user's run is **verified-correct**, and that promise is only kept
-if the migrated engine still delivers every feature below. The acceptance suite is the moat applied
-to mini-ork itself.
-
-## The 9 core promised features + their acceptance probes
-
-Each probe is **end-to-end** (exercises the feature through its real entrypoint) and **replayable**
-(a command or short recipe). A feature is "migrated correctly" only when its probe is green on the
-Python runtime **and** byte-matches the bash runtime where a bash reference still exists.
-
-| # | Promised feature | Real entrypoint | Acceptance probe (end-to-end) |
-|---|---|---|---|
-| 1 | **6-stage loop** classify→plan→execute→verify→reflect→improve | `bin/mini-ork run` | Run `examples/01-hello-world/kickoff.md`; assert every stage emits its artifact (classification.json, plan, execute log, verdict, reflection) and the run reaches a terminal state. |
-| 2 | **Recipe execution** (forced recipe → its contract) | `bin/mini-ork run <recipe>` | Run `code-fix` on a seeded red→green fixture; assert the artifact_contract is satisfied. Run `framework-edit` on a 1-line kickoff; assert it produces a **diff, not a commit**. |
-| 3 | **Heterogeneous lanes + `learning_governed` routing** | `decision_service.decide()` | `MO_VALIDATE_DO_RUNS=1 MO_LEARNING_MIN_SAMPLES=1 scripts/learning-loop-live-validate.sh 1` — assert the router returns the static default BEFORE and the learned lane AFTER. |
-| 4 | **Cost governance** (budget cap + circuit breaker) | `budget_gate`, `cost_pause` | Start a run with a $0.01 per-run cap; assert it halts at the cap and writes the pause sentinel — does not silently overspend. |
-| 5 | **Runtime verify-gate** (the moat) | `bin/mini-ork verify` / `reviewer_gate` | Feed a change that is red-on-base + green-on-gold → assert **pass**. Feed a change that is green-by-coverage-gap (a genuine cheat) → assert **reject**. (Precision on hard negatives, not just apply_fail.) |
-| 6 | **Learning loop closes** (reward → routing) | `scripts/learning-loop-closure-gate.sh` | Run the closure gate; assert a real trace writes reward, GRPO recomputes advantage, and the next `decide()` reads it. |
-| 7 | **`framework-edit` self-modification** (propose-not-commit, blast-radius scope, rollback) | `recipes/framework-edit` | Run a self-edit kickoff; assert scope_gate **blocks** an out-of-scope file, the change lands as a reviewable diff, and rollback restores cleanly. |
-| 8 | **Durable / resumable runs** (checkpoints) | `--resume` | Kill a run mid-step; `--resume`; assert it resurrects at the checkpoint (STEP or TURN) without re-executing completed nodes (idempotency + tool receipts). |
-| 9 | **Multi-epic delivery** (epics + scheduler) | `bin/mini-ork epics split` / `scheduler` | Split a 3-epic roadmap with a dependency; assert the scheduler dispatches in dependency order and does not drain unrelated epics. |
-
-> Probes 3, 5, 6 are the **moat probes** — they prove the *verified-correctness* promise itself.
-> If the migration breaks these, it has broken the product regardless of unit-parity.
-
-## Migration strategy: integration-points first, root → down, one frontier
-
-_Revised 2026-07-18 per the "less deterministic, integration-points first" direction._
-
-The bottom-up leaf approach **splits** integration points: it makes a Python module native but
-leaves the paired bash entrypoint (and every lib/script/test/UI ref to it) still live — a scatter
-of half-open seams with no way to know which are complete. Replace it with a **single advancing
-frontier**:
-
-- **Unit of work = a fork** (an entrypoint's Python↔bash seam), NOT a lib. A fork is "closed"
-  only when **every** integration point is resolved:
-  - **outbound** — what the Python entrypoint shells to (`lib/X.sh` calls), and
-  - **inbound** — every lib, script, test, sandbox, and **web-UI route** that invokes the bash
-    entrypoint `bin/mini-ork-<cmd>`.
-  Then the bash entrypoint retires and the `runtime-select` fallback for that command drops.
-- **Order = root → down.** Dispatcher/`cli` first, then `classify → plan → execute → verify →
-  reflect`, closing each fork completely before descending, so a caller is never migrated after
-  the thing it calls is already gone.
-- **Above the frontier: pure Python. Below: pure bash. Nothing half-open.**
-
-**Why forks, not libs — measured 2026-07-18:** closing the *easiest* fork (`classify`, whose Python
-side is already native) still requires resolving **8 integration points**: `lib/llm-dispatch.sh`,
-`lib/sandbox/local.sh`, `mini_ork/web/routes/run_detail.py` (the UI), `scripts/runtime-parity-harness.sh`,
-`tests/unit/test_mini_ork_classify_py.py`, three `tests/security/*.sh`, and `tests/integration/test_bin_classify.sh`.
-Any one of those, if missed, is a dangling reference to a retired entrypoint. Only a **complete
-integration-point map, resolved as a set**, prevents that.
-
-### Step 0 — the integration-point map (the enforceable safeguard)
-
-Before any transform: compute every Python↔bash edge and every inbound reference to each
-`bin/mini-ork-<cmd>`. This map IS the "don't leave anything incomplete" guarantee — a fork can't be
-declared closed while any edge into it survives. Read-only; produced first.
-
-### Lane policy (per 2026-07-18 decision)
-
-| Loop role | Lane | Backoff | Rationale |
-|---|---|---|---|
-| implementer / worker (the code transform) | **codex** | codex | reliable in this env; implementer must never be GLM (analysis-only) or opus |
-| planner / broad discovery | **Kimi** | codex | authenticated coding lane for decomposition and broad discovery |
-| mapper / ledger / reviewer (judgment — the moat) | **GLM 5.2** | codex | maps each seam, owns the cost/verifiability ledger, and reviews closure evidence |
-
-### Per-fork pipeline (less deterministic — the agent reasons per seam)
-
-1. **Map the seam** (opus) — from Step 0's graph: every outbound shell-out + every inbound ref to
-   this entrypoint (libs, scripts, tests, sandbox, UI). Reason about each edge's contract (env
-   passed, side-effects, stdout capture) — not a fixed template.
-2. **Static-feature ledger** (opus — REQUIRED OUTPUT, see below) — before/while porting, catalog
-   every function/behavior in this part and deliberately classify it static vs agentic. This is the
-   cost/verifiability audit, not bookkeeping.
-3. **Make the Python side sole** (codex) — port/rewire every outbound seam to native
-   (AST-verify the port is native first; preserve `_bash_lib_call`'s `|| echo 0` error-swallowing
-   AND its stdout capture — a printing port leaks into caller stdout, see cross_epic).
-4. **Repoint every inbound ref** (codex) — tests → Python-only (convert bash-oracle parity tests to
-   standalone), UI/lib/script refs → the Python entrypoint or its module.
-5. **Verify** (the moat, made concrete): (a) byte-parity vs the bash oracle on the **live** state.db
-   while it still exists · (b) pytest + pyright 0 · (c) a **real run** · (d) the entrypoint's
-   **feature-acceptance probe** from the manifest above.
-6. **Close the fork** — retire `bin/mini-ork-<cmd>` + drop its `runtime-select` fallback. All gates
-   or nothing lands.
-
-## The static-feature ledger — the migration's strategic payload
-
-This is why the migration is worth more than a port. mini-ork's moat is **cost-down at constant
-verified correctness**, and those two goals share one root cause:
-
-| Kind | Cost | Verifiability |
-|---|---|---|
-| **static** (deterministic logic) | ~0 tokens | **un-gameable** — byte-parity vs an oracle, the strongest verification |
-| **agentic** (LLM call) | tokens per call | **weak** — LLM-judge is gameable (single-test execution-anchoring gets hacked through coverage gaps) |
-
-So each fork migration MUST emit a ledger classifying every behavior it touches. One row per
-function/feature:
-
-| feature | class | verifiability | cost | decision / opportunity |
-|---|---|---|---|---|
-| `aggregate_win_rates` (rho) | **static** (sqlite) | byte-parity (high) | ~0 | keep static — a unit of the moat |
-| `lane_router_*` | **static** (sqlite, 588L) | byte-parity (high) | ~0 | confirm + keep static |
-| `gradient_extract` | **agentic** (native dispatcher) | LLM-judge (weak) | $$ / call | **cost-down candidate**: make template/deterministic, or gate with a deterministic check |
-| `<a runtime-select fork>` | **integration** | — | — | note whether the seam itself is static or agentic |
-
-- **static** confirmed → a unit of the moat proven (cheap + hard-verifiable).
-- **agentic** flagged → a cost *and* verifiability liability, and a candidate to push the RIGHT
-  direction (agentic→deterministic lowers cost and raises verifiability at once). Pure static→agentic
-  is almost never right — it spends tokens and weakens the gate.
-- **integration** → a seam; record whether it carries an LLM or is pure plumbing.
-
-**The aggregate ledger = mini-ork's cost/verifiability map**, and the flagged agentic rows = the
-cost-down roadmap. The migration produces it as a by-product of touching every part with an oracle
-in hand — the one time the whole engine gets read deliberately, function by function.
-
-## The observe → improve loop (why this compounds)
-
-Every gate failure is a **verifier gap**, and fixing it hardens mini-ork for *all* jobs, not just
-migration:
-
-| Issue observed this session | Verifier gap | Improvement (general, not migration-specific) |
-|---|---|---|
-| lib deleted while `bin/` still called it | discover stage missed `bin/` | `bin/` added to the retirement blocker-check |
-| unit-parity passed, stdout leaked | unit-parity too shallow | the end-to-end probe is now a **required** gate |
-| differential test flaked (shared-db `bug_report_sweep`) | verifier's test isolation weak | per-implementation db copies |
-| now/now-epoch boundary race | time-relative tests un-buffered | seed now-offset timestamps |
-
-This is the compounding curve: the migration is the cheap, oracle-backed workload that *pays for*
-verifier hardening; the hardened verifier then does the next un-shelling — and the next non-migration
-job — more reliably. The migration doesn't just finish; it makes the thing that finishes it better.
-
-## Open question for sanity-check
-
-Are these the right **9 features**, or is a promised capability missing (e.g. trace capture /
-observability as a standalone feature, or the HarnessBridge / cross-runtime story)? The recipe and
-the acceptance-probe scripts both gate on this list, so it's worth pinning before building them.

-# Environment variables
-
-MiniOrk works with no environment variables for a local project. Set the
-variables below only to change where state is stored, separate engine and
-target repositories, or enable an explicitly documented runtime behavior.
-
-## Core paths
-
-| Variable | Default | Purpose |
-|---|---|---|
-| `MINI_ORK_ROOT` | MiniOrk engine root | Locates shipped recipes, migrations, and configuration. |
-| `MINI_ORK_HOME` | `.mini-ork/` under the project | Stores project-local state, configuration, and run artifacts. |
-| `MINI_ORK_DB` | `$MINI_ORK_HOME/state.db` | Overrides the SQLite state database path. |
-| `MINI_ORK_PROJECT_HOME` | current project | Identifies the project MiniOrk is operating for. |
-| `MINI_ORK_TARGET_REPO` | current project | Identifies the repository available to agent and verifier work. |
-| `MINI_ORK_ENGINE_ROOT` | resolved engine root | Overrides engine discovery for installed launchers. |
-
-`MINI_ORK_DB` takes precedence over the database path derived from
-`MINI_ORK_HOME`. Keep each concurrent project or test run on its own home and
-database path.
-
-## Credentials
-
-Configure provider credentials with the CLI instead of passing keys on command
-lines:
-
-```bash
-mini-ork providers configure <lane>
-mini-ork providers status <lane>
-```
-
-The command writes local credentials to
-`$MINI_ORK_HOME/config/secrets.local.sh`, which is ignored by Git. See
-[provider triage](provider-triage.md) for provider-specific diagnosis.
-
-## Runtime behavior
-
-Advanced `MO_*` and `MINI_ORK_*` switches are cataloged in
-[Feature flags](feature-flags.md). Set only the flags required by a specific
-runbook or recipe; defaults are selected to keep the standard CLI path safe.
-
-Two common extension selectors are:
-
-| Variable | Purpose |
-|---|---|
-| `MO_ROUTING_POLICY` | Chooses a registered native routing policy. |
-| `MO_EMBED_PROVIDER` | Chooses a registered semantic-memory embedder. |
-
-Do not use the retired `MINI_ORK_RUNTIME` selector. The supported framework
-runtime is native Python; shell execution remains available only for declared
-recipe verifier, target-repository, migration, and sandbox boundaries.

-# Plan — Bash removal: complete the Python cutover
-
-*2026-07-26 · implementation status updated 2026-07-29: Phases 0–4 complete; Phase 5 release verification remains*
-
-> **Implementation record.** The Python runtime is now the only framework
-> runtime: `lib/` and `gates/` contain no shell runtime files, compatibility
-> commands in `bin/` re-exec the native dispatcher, and parity tests were
-> converted to native unit tests. The Phase 0–4 descriptions below are kept as
-> the decision record for the cutover, not as instructions to restore Bash.
-
-## 0. Reality check at plan time (why this was a cutover, not a deletion)
-
-`MINI_ORK_RUNTIME=python` was the default and the Python runtime was live, but
-Bash was still **load-bearing in the default production path**:
-
-1. **Trampoline**: `mini-ork <sub>` → Python `cli/main.py` →
-   `_bash_entrypoint_handler` → `bin/mini-ork-*` (bash) → `runtime-select.sh`
-   → `exec python3 -m …`. Bash is a live intermediary for 21 subcommands.
-2. **4 subcommands have no Python port at all**: `apply`, `garden`,
-   `validate`, `recipe-eval` — they execute real bash today.
-3. **22 production Python→bash subprocess sites** (the blockers, §3 of the
-   inventory): `db/init.sh` migrations, `lib/trace_store.sh` writes,
-   5 gate-condition scripts, `lib/cw_por.sh`, `lib/gate_registry.sh` shell
-   calls, `finalize.py`/`healer_bridge.py`/`benchmark_suite.py` bash-lib
-   calls, 7 provider `cl_*.sh` lane wrappers, `lib/runtime/contract.sh`.
-4. **56 `recipes/*/verifiers/*.sh`** — a user-facing recipe contract whose
-   runner is `["bash", script]`.
-5. **~90 Python parity tests** shell out to their bash twin; **82 `.sh`
-   tests** + `tests/run-all.sh`/`smoke.sh` pin the bash side; CI has
-   shellcheck + bash-tests jobs; Makefile/.githooks/scripts are bash.
-
-Deleting bash before eliminating 1–4 breaks production. The phases below are
-therefore strictly ordered: **replace → cut over → delete → convert tests →
-strip tooling**.
-
-Foundations already in place (this year's refactors): every bash lib has a
-parity-verified Python port staged (`docs/migration/parity-ports.md`);
-subcommand/node/gate/policy/provider **registries** make cutovers
-configuration, not surgery; `stores/migrate.py` is a staged Python migration
-runner; the web/obs surface is fully Python.
-
-## Phase 0 — Freeze and guardrails (0.5 day)
-
-- Announce: no new `.sh` anywhere; new recipes write Python verifiers.
-- Add a CI guard: fail if the count of `lib/*.sh` files *increases*
-  (ratchet the inventory: 73 lib + 6 gates + 82 test .sh today).
-- Land this plan; tag the repo (`pre-bash-removal`) for rollback reference.
-
-**Exit:** guardrail CI green.
-
-## Phase 1 — Eliminate production bash dependencies (ordered by risk, smallest first)
-
-Each workstream ships independently with its own green gate. Rule: the
-Python replacement must be the *staged parity port* where one exists — the
-parity tests already prove equivalence.
-
-### WS1 — Subcommand cutover (removes the trampoline)
-- Port the 4 bash-only subcommands to `mini_ork/cli/{apply,garden,validate,recipe_eval}.py`
-  (their bash bodies: `bin/mini-ork-apply` + `lib/apply.sh`,
-  `bin/mini-ork-garden`, `bin/mini-ork-validate`, `bin/mini-ork-recipe-eval`).
-- Register all 21 `_EXEC_SUBS` as native module handlers in
-  `SUBCOMMAND_REGISTRY`; delete `_bash_entrypoint_handler` and `_EXEC_SUBS`.
-- **Exit:** `mini-ork <sub> --help` for all 21 works with `bin/mini-ork-*`
-  renamed away (test proves no trampoline).
-
-### WS2 — Python migration runner
-- Cut `cli/init.py` + `cli/update.py` from `bash db/init.sh` to
-  `mini_ork.stores.migrate` (staged); port the sqlite-grep one-liner in
-  `update.py:125`.
-- **Exit:** `mini-ork init` on a fresh HOME produces the 111-table db with no
-  `db/init.sh` present; `test_migrate_py.py`, `test_mini_ork_update_py.py`
-  green after conversion (Phase 3).
-
-### WS3 — trace_store writes
-- `cli/invoke_prompt.py` + `cli/reflect.py` write via
-  `mini_ork.trace_store` (staged port) instead of `bash -c '… trace_store.sh'`.
-- **Exit:** no `trace_store.sh` references in production code.
-
-### WS4 — Gates: native evaluators for the 5 gate scripts
-- The M5 `GATE_EVALUATORS` registry makes this registration, not surgery:
-  port `gates/{coalition,liveness,panel-health,stability,synthesis-promote}.sh`
-  semantics into evaluators over the staged ports (`coalition_gate.py`,
-  `circuit_breaker.py`, `cw_por.py`, `adaptive_stability.py`,
-  `promotion_gate.py`) and re-register the bootstrap conditions to native
-  evaluators instead of script paths.
-- `gates/artifact_contract.py:192` and `promotion_gate.py:370` switch from
-  `bash -c 'source lib/{gate_registry,cw_por}.sh'` to the Python ports.
-- **Exit:** `gate_run_all` passes with `gates/*.sh` absent; oracle-gate
-  integration tests green.
-
-### WS5 — Recovery + learning bash-lib calls
-- `recovery/finalize.py` (cache/finalize/auto-merge/pr-create),
-  `recovery/healer_bridge.py` (cleaner/healer),
-  `learning/benchmark_suite.py` (utility_function) — call the staged Python
-  ports directly.
-- **Exit:** those modules import no `bash`; recovery + learning suites green.
-
-### WS6 — Provider lane wrappers (`cl_*.sh`, 7 lanes) — HARDEST
-- The wrappers carry real contracts: argv assembly, credential injection,
-  codex's JSONL→sidecar telemetry protocol, glm/minimax gateway quirks.
-- Path: for each lane, express the wrapper's contract in
-  `config/providers.yaml` (kind registry from M6 supports this) and delete
-  the wrapper. `cl_codex.sh` needs a native codex transport (the
-  `_dispatch_codex_via_wrapper` backend already exists — extend it to own
-  the sidecar protocol).
-- **Exit:** live dispatch smoke on all 7 lanes with `lib/providers/` absent
-  (run in the mini-ork env, real creds; gate: `test_providers_live.sh`
-  replacement).
-
-### WS7 — Sandbox runtime contract
-- `agent/minimal.py` shells to `lib/runtime/contract.sh`
-  (+bubblewrap/docker/local backends). Either port the contract to
-  `mini_ork/runtime/` or retire the minimal scaffold (`MO_SCAFFOLD_TIER`
-  defaults to `harness`; the minimal tier is opt-in).
-- **Exit:** decision recorded; scaffold tier green either way.
-
-### WS8 — Recipe verifier contract
-- Verifiers are user-facing recipe content; the runner executes
-  `["bash", script]` (`cli/verify.py:183,194`, `cli/execute.py:1119`).
-- Change the runner to dispatch by extension: `.py` →
-  `[sys.executable, script]`, `.sh` → bash (legacy, deprecated warning).
-- Port the 56 built-in `recipes/*/verifiers/*.sh` to `.py` (mechanical —
-  most are small: typecheck/test/lint wrappers).
-- **Exit:** all built-in recipes verify with no `.sh` under `recipes/`;
-  external `.sh` verifiers still run (compat) but warn.
-
-## Phase 2 — Delete the bash runtime (complete)
-
-- Delete `bin/mini-ork-*` bash bodies → replace each with a thin
-  `exec python3 -m <module>` shim (or fold into `bin/mini-ork <sub>` only
-  and drop the suffixed wrappers — decide; keeping thin shims preserves
-  muscle memory).
-- Delete `lib/runtime-select.sh`, `lib/paths.sh`, all 73 `lib/*.sh`,
-  6 `gates/*.sh`, `bin/_worker-launcher.sh`, `bin/mo-check-claude-invocations`
-  (Python port exists).
-- Remove `MINI_ORK_RUNTIME` handling and the `doctor` lib-presence checks.
-- **Exit:** full pytest green with zero `.sh` in `bin/ lib/ gates/`. Achieved
-  for the framework runtime; `db/init.sh` remains an external compatibility shim
-  that immediately `exec`s `mini_ork.stores.migrate`.
-
-## Phase 3 — Test migration (complete)
-
-- Convert ~90 parity `*_py.py` tests to plain unit tests: drop the
-  bash-subprocess half, keep the Python assertions (most already have
-  python-only cases; the parity layer is partially decoupled — 17 stale
-  pins already pass with twins absent).
-- Delete the 82 `.sh` tests, `tests/run-all.sh`, `tests/smoke.sh`,
-  `tests/lib/setup_state_db.sh` (replace with a Python conftest fixture).
-- **Exit:** pytest suite count stabilizes ≈ python-only; no test spawns
-  `bash` except recipe-verifier compat tests (WS8).
-
-## Phase 4 — Tooling, CI, docs (complete, with historical-doc sweep tracked separately)
-
-- **CI**: delete `shellcheck` + `bash-tests` jobs; delete
-  `mo-check-claude-invocations` advisory step (port is Python — wire it as
-  a pytest or a ruff-style check); keep `readme-claim-check` (port to
-  Python or keep as the one sanctioned script).
-- **Makefile**: retarget `serve/dev/test-obs/worktree*` to Python entry
-  points (port `scripts/mini-ork-worktree.sh` — it is the worktree-first
-  dev loop, high value).
-- **.githooks**: port `pre-push`/`post-commit`/`reference-transaction` to
-  Python (they're repo-critical: worktree guard + README drift).
-- **scripts/**: port or delete the 16 (most are one-off smokes → delete;
-  `mini-ork-worktree.sh` + `readme-*.sh` → port).
-- **hooks/*.sh** (Claude Code integration): port to Python entry points or
-  document as the one external bash surface (decision; they are
-  Claude-side glue, not mini-ork runtime).
-- **Docs**: rewrite `AGENTS.md` (drop `MINI_ORK_RUNTIME=bash`,
-  `lib/paths.sh`, shellcheck references), `docs/operator/*`, and sweep the
-  106 files referencing `.sh` paths; update `.github/CODEOWNERS`.
-- **Exit:** no internal Python subprocess targets a retired `lib/` or
-  `gates/` runtime path; CI green with the Bash-only jobs removed. Shell
-  execution remains allowed at explicit external boundaries: legacy recipe
-  verifiers, target-repository commands, migration SQL compatibility, and
-  sandboxed user commands.
-
-## Phase 5 — Verification & rollout (remaining)
-
-- Full suite + live smoke (real lanes) in the mini-ork env.
-- Bump minor version; changelog entry: "bash runtime removed".
-- Keep `pre-bash-removal` tag + one release of the thin-shim bins before
-  dropping suffixed wrappers entirely (if that option is chosen).
-
-## Risk register
-
-| Risk | Mitigation |
-|---|---|
-| Provider wrappers carry undocumented lane quirks (WS6) | Lane-by-lane live smoke before deletion; keep wrappers one release behind a feature flag |
-| Parity tests hide behavior only the bash half asserted | Conversion reviews each parity test for bash-only assertions before dropping |
-| Recipe verifiers are a public contract (WS8) | Extension-based runner keeps `.sh` working with a deprecation warning for ≥1 release |
-| 40+ tests pin `db/init.sh` | WS2 lands the Python runner first; tests migrate in Phase 3 with a conftest fixture |
-| Hidden bash callers in consumer repos | `mini-ork doctor` gains a "bash references" check pre-removal; release notes call out |
-
-## Effort estimate

-# Plan — truth-grounded eval: from LLM judge to a verification stack
-
-*2026-07-30 · supersedes the "LLM judge writes the reward" shape of the Step-3
-eval node (`internal-docs/research/2026-07-03-adding-eval-to-miniork-run-flow.md`).*
-
-## Why
-
-LLM-as-judge is unreliable as a reward source, and the literature is blunt about
-it. On mini-ork's exact setup — critic-free GRPO on code — using an LLM as the
-reward scored **5.8 points below** execution-grounded reward (76.3 vs 82.1;
-EGCA, arXiv 2603.16158), and that paper uses the LLM only to *localize/explain*
-an error, explicitly "not as a correctness oracle." Direct measurement of
-verifier vs judge false-positives on MATH500: a **rule-based verifier had 0
-false-positives out of 500; an LLM verifier had 168** (arXiv 2510.00915). The
-fix for "the judge is unreliable" is not a better judge — it is **demoting the
-judge** beneath signals that are true by construction.
-
-## The stack (most → least trusted). Reward flows from the top.
-
-| Layer | Signal | Source in mini-ork | Trust |
-|---|---|---|---|
-| **0 Execution** | tests + constraints actually run: `R = pass_fraction × constraint_ind` | `recipes/*/verifiers/*.py`, `cli/verify.py` verdict (`pass/partial/fail/vacuous`) | highest |
-| **1 Noise model** | verifiers are ALSO noisy (FN 38%, FP 35–68%); de-bias the reward | `verifier_fp_rate` (mig 0025) + FN sibling; backward correction | high |
-| **2 Metamorphic** | invariances across related runs (gold-free); catches "passed one test via a coverage gap" | new: metamorphic-relation verifier | medium |
-| **3 Judgment** | decorrelated JURY, veto-only, contested cases only | coalition gate + Krippendorff-α + 4-family routing; the Phase-0 judge | lowest |
-
-Grounding: 2603.16158 (EGCA, execution > judge, exec-only oracle), 2510.00915
-(imperfect verifiers + backward/forward gradient correction + online FN
-estimation via appeals), 2603.24774 / 2510.26423 (metamorphic + oracle
-synthesis, gold-free), 2607.10139 (jury > PRM), 2510.20369 (escalate to a strong
-judge only when uncertain), 2506.09443 (LLM judges are manipulable).
-
-### Layer 1 — the backward correction (faithful to 2510.00915)
-
-For an observed execution reward `R ∈ [0,1]` with verifier false-positive rate
-`ρ_FP` (accepts a wrong result) and false-negative rate `ρ_FN` (rejects a correct
-one), the unbiased surrogate reward is:
-
-```
-R_corrected = (R − ρ_FP) / (1 − ρ_FP − ρ_FN)          (clamp to [0,1])
-```
-
-Guard: if `1 − ρ_FP − ρ_FN ≤ 0` (rates over-estimated), skip the correction and
-return `R` — the inverse factor amplifies variance, and the paper shows
-over-estimation is where it degrades. Rates come from `verifier_results`
-annotations (`is_false_positive` / `is_false_negative`) when labeled; otherwise
-conservative priors (`MO_EVAL_VERIFIER_FP_PRIOR` / `_FN_PRIOR`), logged as priors.
-
-### The demotion (how the judge is confined)
-
-- **Execution signal present** (≥1 verifier reported a pass/fail): reward =
-  `noise_correct(R_exec)`, `reward_source='eval-exec@v1'`. The judge runs only
-  for what execution can't measure (groundedness, safety) and is **veto-only** —
-  it multiplies the reward by `min(safety, groundedness) ≤ 1`, so it can pull the
-  reward down but never above the execution ceiling. Mirrors the existing
-  anti-Goodhart rule in `writeback.py` (reward verified execution; a judge can
-  veto, never fabricate a positive).
-- **No execution signal** (`vacuous`, or no verifiers ran): fall back to
-  judge-only (`reward_source='eval-judge@v1'`), logged as lower-trust. A
-  `vacuous` run must never earn a high reward (anti-false-completion).
-
-## Phasing
-
-- **Phase 0 (shipped, `fe9ee3e2`)** — advisory judge node, per-axis + fail-open. Becomes Layer 3.
-- **Phase 1 (this change)** — Layers 0+1: execution-grounded reward as the backbone, backward noise correction, judge demoted to veto-only. `reward_source` splits into `eval-exec@v1` / `eval-judge@v1`.
-- **Phase 2 (engine shipped)** — metamorphic-relation verifier (gold-free amplification): `mini_ork/learning/metamorphic.py` (engine: relations + universal determinism/immutability checks; execution-grounded verdict via `to_verifier_json()` → feeds Layer 0 as one more `verifier_*.json`) + `recipes/code-fix/verifiers/metamorphic.py` (spec-driven via `MO_METAMORPHIC_SPEC`; a vacuous no-op without a spec). Proven to catch a coverage-gap cheat that a single extensional test passes. **Safe auto-proposal shipped** (`mini_ork/learning/metamorphic_proposer.py`): an LLM SELECTS relations as VALIDATED DATA — names from the vetted `RELATION_LIBRARY` whitelist + JSON seed inputs — never executable code. `parse_proposal` drops any unknown/garbage name (the safety boundary; tested against `__import__` / `rm -rf` names), and the verifier gained a data-only JSON-spec path (`MO_METAMORPHIC_SPEC_JSON`) that resolves relations by name and imports only the run's own patched target. No model-authored code is ever `exec`'d (arXiv 2603.24774 — LLM proposes, execution certifies). Library: determinism, commutativity, negation_invariance, order_invariance. **Final connection (open):** a recipe proposer node that dispatches the LLM, identifies the changed function from the diff, and writes the JSON spec before the metamorphic verifier — target-identification for arbitrary code is the remaining flaky part, kept out until it's robust rather than shipped as theater.
-- **Phase 3 (jury shipped)** — the veto now comes from a DECORRELATED PANEL, not one judge. Set `MO_EVAL_JURY_LANES=lane1,lane2,…` (different model families) and the eval node dispatches each, aggregates the veto by median consensus (`panel_consensus`, robust to one bad lens; 2607.10139), and gates on inter-judge agreement (`panel_agreement`, the Krippendorff pairwise-disagreement kernel): below `MO_EVAL_JURY_ALPHA_MIN` (default 0.5) the panel **abstains** — the execution reward stands rather than applying a veto the judges can't agree on (2510.20369). Degenerates cleanly to a single judge when one lane is set. **Selective escalation shipped:** on a hung jury, `MO_EVAL_JURY_ESCALATE_LANE` dispatches one strong tiebreaker judge whose veto decides (the "ask a strong judge when uncertain" rail, 2510.20369), rather than silently abstaining; and a jury drawn from a single model family logs a not-decorrelated warning via the `coalition_gate` family map (advisory, never blocks).
-- **Phase 4** — online FN estimation ("appeals"): a cheap lane re-checks suspected false-negatives to estimate `ρ_FN` live and feed `verifier_results`.
-
-## DoD (Phase 1)
-
-A `code-fix` run derives `reward_value` from its verifiers (not the judge),
-noise-corrected; the judge can only downgrade; a vacuous/no-verifier run falls
-back to judge-only and is flagged; unit + integration tests cover execution
-reward, the backward correction (incl. the over-estimation guard), the veto, and
-the fallback.

-
-## Specced / roadmap (not shipped as mainline) (5 features)
-- **Eval-in-run-flow: metamorphic (P2) + jury (P3)** — `type:eval` node ships and writes reward cols, but LLM judge is DEMOTED to veto-only; metamorphic + jury layers specced not shipped — `recipes/eval-judge/prompts/`; `mini_ork/cli/recipe_eval.py:1`. [specced/partial]
-- **GEPA live reflective evolution at scale** — `MiniOrkGEPAAdapter` is import-clean and wired, but consumed only by a research recipe; mainline uses `apply`/`role-evolver` — `mini_ork/gepa/miniork_adapter.py:81`. [specced/partial]
-- **Full `web/dist` React bundle** — repo ships the manifest entrypoint; full bundle built separately (`pnpm build`), API-only otherwise — `mini_ork/web/app.py:116`; `mini_ork/web/static/index.html:1`. [specced/partial]
-- **Pre-push review panel as default merge gate** — panel CLI exists; enforcement is opt-in git-hook wiring, not default-on — `mini_ork/pre_push_review.py:1`. [specced/partial]
-- **Adaptive conductor gain auto-engagement** — `_adaptive_lane_gain` fires only past `MO_CONDUCTOR_GAIN_MIN_SAMPLES`; ships cold at default 0.3 below threshold — `mini_ork/orchestration/conductor.py:37`. [specced/cold-default]
-
-## Disputed entries
-- **Watchdog maturity** — minimax: shipped orphan-process reaper — `mini_ork/orchestration/watchdog.py:1`. glm: `[STATUS: incomplete]` "scaffold only; not yet wired to circuit-breaker dispatch" — `mini_ork/cli/watchdog.py`. Verdict: module exists; dispatch wiring unproven → treat as partial.
-- **`usage-report` maturity** — minimax: shipped `collect_region_expertise`+`render_json` — `mini_ork/observability/usage_report.py:1`. glm: `[STATUS: incomplete]` "recently added; surface coverage rough" — `mini_ork/cli/usage_report.py:160`.
-- **`bug-collector` wiring** — minimax: shipped heuristic/llm modes — `mini_ork/observability/bug_collector.py:1`. glm: `[STATUS: incomplete]` "collector wiring rough; overlap of `cli.bugs` + `cli.bug_collector`" — `mini_ork/cli/bug_collector.py`.
-- **Apply loop anchor** — minimax cites `mini_ork/cli/apply.py:609` (`apply_run`); kimi cites `mini_ork/cli/apply.py:96` (`apply_run`). Both valid entrypoints into the same close-the-loop flow; no maturity dispute.
-- **GEPA maturity** — minimax: `[specced/partial]` (adapter wired, mainline uses apply/role-evolver) — `mini_ork/gepa/miniork_adapter.py:81`. glm: presents `/api/v1/learning/gepa` endpoint as shipped surface. Reconciled as specced/partial (endpoint exists, mainline evolution loop does not consume the adapter).
-- **`framework-edit` verifier** — glm: `[STATUS: flagged]` "verifier never emits `verdict.json`; gate-by-reviewer-pass fallback" — `mini_ork/cli/verify.py:175`. No counter-claim from other lenses; carried into coverage gaps.
-
-## Coverage gap report
-- **No `mini-ork traces`/`llm-calls` shell surface** — `llm_calls` is web-only (`mini_ork/web/routes/run_detail.py:537`); cost-per-(lane,recipe,day) only via `/cost-by-day`. Operators must hit HTTP or sqlite3 directly. [minimax gap 1]
-- **Apply-loop GEPA scorer is a stub** — `MO_APPLY_SCORER=gepa` collapses to neutral mock `"0.5 1"` on import failure — `mini_ork/cli/apply.py:296`. [minimax gap 2]
-- **Durable-DAG resume UX split from `mini-ork resume`** — `resume` clears cost-pause sentinel (`mini_ork/cli/resume.py:127`); "died at node X, resume from X" lives under `recover`+`recovery.planner`, not one CLI. [minimax gap 3]
-- **Conductor budget projection is shallow** — `_today_cost` checks 24h rolling spend but does not project per-epic; the `$50/day` cap is enforced per self-improve iter (`mini_ork/cli/self_improve.py:198`) not mid-run for the live scheduler — `mini_ork/orchestration/conductor.py:24`. [minimax gap 4]
-- **No `process_reward` investigation surface** — written by executor (`mini_ork/cli/execute.py`), shown via conductor endpoint, but no shell "why did node X score 0.42?" — diagnostic only at `mini_ork/web/routes/run_detail.py:192`. [minimax gap 5]
-- **No cross-recipe learning-portability surface** — `mini_ork/learning/cross_epic_gradient.py:1` exists but is not exposed via any `/api/v1/learning/` route; can't ask "what has the system learned about implementer prompts across all recipes?". [minimax gap 6]
-- **Observability spans absent on hot paths** — no OTel/withFeature span crosses dispatch, GRPO writeback, cost-circuit, lane-fuse, or the recovery planner; cost-circuit and lane-fuse emit stderr only, with no persistent row to graph "lane was OPEN" — `mini_ork/dispatch/llm_dispatch.py:177`, `mini_ork/learning/writeback.py:144`. [codex OBS gaps: Flows 7/11/12/18/22]
-- **`framework-edit` verifier never emits `verdict.json`** — always renders `needs_revision`; gate falls back to reviewer-pass — `mini_ork/cli/verify.py:175`. [glm flagged]
-- **`eval-judge` metamorphic (P2) + jury (P3) specced, not shipped** — LLM judge is veto-only today — `mini_ork/cli/recipe_eval.py:1`; `recipes/eval-judge/prompts/`. [glm incomplete]
-- **`watchdog` / `usage-report` / `bug-collector` partially wired** — each has a module but rough or unproven runtime wiring; see Disputed entries — `mini_ork/orchestration/watchdog.py:1`, `mini_ork/observability/usage_report.py:1`, `mini_ork/observability/bug_collector.py:1`.

-# Feature inventory (synthesis)
-
-Code-grounded catalog of mini-ork as a cloud agent orchestration platform.
-Consolidates 4 lens reports (codex, minimax, kimi, glm) into the 7 pillars
-from the kickoff. Every feature carries a `file:line` anchor and a
-`shipped`|`specced` marker. `[CONSENSUS: N/4]` = number of lenses that
-independently surfaced the feature.

-- **Pre-push review panel as default merge gate** — panel CLI exists; enforcement is opt-in git-hook wiring, not default-on — `mini_ork/pre_push_review.py:1`. [specced/partial]
-- **Adaptive conductor gain auto-engagement** — `_adaptive_lane_gain` fires only past `MO_CONDUCTOR_GAIN_MIN_SAMPLES`; ships cold at default 0.3 below threshold — `mini_ork/orchestration/conductor.py:37`. [specced/cold-default]

-## Disputed entries
-- **Watchdog maturity** — minimax: shipped orphan-process reaper — `mini_ork/orchestration/watchdog.py:1`. glm: `[STATUS: incomplete]` "scaffold only; not yet wired to circuit-breaker dispatch" — `mini_ork/cli/watchdog.py`. Verdict: module exists; dispatch wiring unproven → treat as partial.
-- **`usage-report` maturity** — minimax: shipped `collect_region_expertise`+`render_json` — `mini_ork/observability/usage_report.py:1`. glm: `[STATUS: incomplete]` "recently added; surface coverage rough" — `mini_ork/cli/usage_report.py:160`.

-
-## Coverage gap report
-- **No `mini-ork traces`/`llm-calls` shell surface** — `llm_calls` is web-only (`mini_ork/web/routes/run_detail.py:537`); cost-per-(lane,recipe,day) only via `/cost-by-day`. Operators must hit HTTP or sqlite3 directly. [minimax gap 1]
-- **Apply-loop GEPA scorer is a stub** — `MO_APPLY_SCORER=gepa` collapses to neutral mock `"0.5 1"` on import failure — `mini_ork/cli/apply.py:296`. [minimax gap 2]
-- **Durable-DAG resume UX split from `mini-ork resume`** — `resume` clears cost-pause sentinel (`mini_ork/cli/resume.py:127`); "died at node X, resume from X" lives under `recover`+`recovery.planner`, not one CLI. [minimax gap 3]
-- **Conductor budget projection is shallow** — `_today_cost` checks 24h rolling spend but does not project per-epic; the `$50/day` cap is enforced per self-improve iter (`mini_ork/cli/self_improve.py:198`) not mid-run for the live scheduler — `mini_ork/orchestration/conductor.py:24`. [minimax gap 4]
-- **No `process_reward` investigation surface** — written by executor (`mini_ork/cli/execute.py`), shown via conductor endpoint, but no shell "why did node X score 0.42?" — diagnostic only at `mini_ork/web/routes/run_detail.py:192`. [minimax gap 5]
-- **No cross-recipe learning-portability surface** — `mini_ork/learning/cross_epic_gradient.py:1` exists but is not exposed via any `/api/v1/learning/` route; can't ask "what has the system learned about implementer prompts across all recipes?". [minimax gap 6]
-- **Observability spans absent on hot paths** — no OTel/withFeature span crosses dispatch, GRPO writeback, cost-circuit, lane-fuse, or the recovery planner; cost-circuit and lane-fuse emit stderr only, with no persistent row to graph "lane was OPEN" — `mini_ork/dispatch/llm_dispatch.py:177`, `mini_ork/learning/writeback.py:144`. [codex OBS gaps: Flows 7/11/12/18/22]
-- **`framework-edit` verifier never emits `verdict.json`** — always renders `needs_revision`; gate falls back to reviewer-pass — `mini_ork/cli/verify.py:175`. [glm flagged]
-- **`eval-judge` metamorphic (P2) + jury (P3) specced, not shipped** — LLM judge is veto-only today — `mini_ork/cli/recipe_eval.py:1`; `recipes/eval-judge/prompts/`. [glm incomplete]
-- **`watchdog` / `usage-report` / `bug-collector` partially wired** — each has a module but rough or unproven runtime wiring; see Disputed entries — `mini_ork/orchestration/watchdog.py:1`, `mini_ork/observability/usage_report.py:1`, `mini_ork/observability/bug_collector.py:1`.

-# Durability, resilience, and precise resume: lessons for MiniOrk
-
-**Status:** source-grounded research; no MiniOrk runtime behaviour changes in this document.
-**Snapshot date:** 2026-07-27
-
-## The short answer
-
-Durable agent execution is not “save the chat, then retry.” It is the ability
-to identify an exact, valid execution boundary; prove which work may be reused;
-and safely rerun everything after that boundary without duplicating an external
-side effect.
-
-MiniOrk already has the essential foundation:
-
-- artifact-manifest checkpoints tied to the resolved inputs, recipe version,
-  and configuration;
-- a single-writer lease with fencing, so a stale recovery cannot publish over a
-  newer one;
-- idempotent recovery requests; and
-- receipts for MiniOrk-owned non-idempotent tools.
-
-The clearest next improvement is **immutable checkpoint history**. Today a
-recovery can deliberately start from a named workflow node. It cannot yet name
-and fork from one particular historical revision of that node's checkpoint.
-
-## Scope and evidence
-
-I cloned these upstream repositories into a temporary directory and read the
-implementation, not only the project descriptions. The links below pin the
-source snapshots used for this note.
-
-| Project | Role in the ecosystem | Source snapshot |
-| --- | --- | --- |
-| LangGraph | durable state-machine runtime | [`30c4d58`](https://github.com/langchain-ai/langgraph/tree/30c4d58db86455128e42ddec96b1ba53c553ba22) |
-| LangChain | agent composition and policy middleware | [`39701d6`](https://github.com/langchain-ai/langchain/tree/39701d6b8e9dc62b57f63fec1d10d2d1f4293303) |
-| DeepAgents | long-horizon agent assembly on LangChain/LangGraph | [`6b1a136`](https://github.com/langchain-ai/deepagents/tree/6b1a136702b4ccfd6fb30a0e53c2ff23f999f847) |
-
-The current LangGraph documentation independently corroborates the checkpoint,
-interrupt, replay, and fork semantics described here: [checkpointers](https://docs.langchain.com/oss/python/langgraph/checkpointers)
-and [time travel](https://docs.langchain.com/oss/python/langgraph/use-time-travel).
-
-## A safe resume has two boundaries
-
-There are two distinct things a system might mean by “resume.” They should not
-be conflated.
-
-1. **State boundary.** Restore a known state and decide which graph node or
-   workflow node runs next.
-2. **Effect boundary.** Prevent an already completed external action—such as a
-   commit, deployment, ticket update, or API POST—from running again while the
-   state is replayed.
-
-LangGraph is strong at the first boundary. MiniOrk's tool receipts and publish
-fence address the second. A robust software-agent system needs both.
-

-    J -- no --> L[Record failure and choose recovery]
-    L --> M[Select named node or checkpoint revision]
-    M --> B
-```
-
-The checkpoint confirms durable work. It does **not** retroactively make a
-side effect safe. The receipt is what makes replay safe.
-
-## What the three projects actually provide
-
-### LangGraph: a durable graph kernel
-
-LangGraph represents a checkpoint as more than a serialized state value. Its
-checkpoint contains channel values, channel versions, each node's observed
-versions, pending writes, parent checkpoint references, source, step, and run
-identifier. A checkpoint is addressed by a `thread_id`, a checkpoint namespace,
-and optionally a `checkpoint_id`.
-
-That identity enables three useful operations:
-
-| Operation | How LangGraph models it | MiniOrk equivalent or lesson |
-| --- | --- | --- |
-| Continue normally | Load the newest checkpoint for a thread | Resume from the earliest non-reusable workflow node |
-| Inspect a past point | List state history and select a snapshot | Expose checkpoint history and its manifest/validity evidence |
-| Fork safely | Update state from an explicit historical snapshot, creating a new lineage | Create a new recovery/fork identity; never overwrite the original evidence |
-
-Its `interrupt()` mechanism makes an important safety rule explicit: resuming
-an interrupt re-executes the node from its beginning. Therefore an interrupting
-node must not perform an unprotected non-idempotent action before the
-interrupt. This is directly relevant to MiniOrk's user gates and recovery
-boundaries.
-
-LangGraph also makes a meaningful durability trade-off visible: `sync` persists
-before the next step, `async` persists while the next step runs, and `exit`
-persists only at the end. For MiniOrk, dispatch, recovery, escalation,
-verification, promotion, and human-approval boundaries are worth the stronger
-`sync`-like rule. Cheap, reconstructible telemetry can remain asynchronous.
-
-Its SQLite saver uses WAL and separate checkpoint/write tables, but explicitly
-positions SQLite as a lightweight synchronous option rather than a
-multi-threaded production store. That matches MiniOrk's current local
-`state.db` use. It is not evidence that a fleet of independent workers can
-safely share one SQLite file.
-
-### LangChain: policy at the agent boundary
-
-LangChain's `create_agent` accepts a LangGraph checkpointer and a cross-thread
-store; it delegates durable graph state to LangGraph rather than providing a
-second competing persistence model. Its main contribution here is middleware:
-
-- `HumanInTheLoopMiddleware` can pause specific tool calls and accepts explicit
-  approve, edit, reject, or respond decisions.
-- `ToolRetryMiddleware` retries configured exceptions with bounded exponential
-  backoff and jitter.
-- model and tool call limit middleware keeps per-thread and per-run counters in
-  agent state, preventing a loop from silently exceeding a configured budget.
-
-The lesson is **not** to copy a generic middleware stack. MiniOrk should keep
-the durable decision record already implied by its recipe, artifact contract,
-verifier, and promotion model. The useful pattern is to turn policy choices
-into structured evidence: what was proposed, why it was allowed or blocked,
-which limit applied, and what evidence is required next.
-
-One deliberate non-adoption: LangChain's retry middleware retries in-process.
-It is useful for transient read-only operations, but it is not a durable work
-queue and does not by itself make an arbitrary write action safe to retry after
-a process crash.
-
-### DeepAgents: long-horizon task ergonomics, not a new durability layer
-
-DeepAgents composes LangChain middleware and forwards the same `checkpointer`
-and `store` into the resulting agent. It contributes useful operational
-patterns:
-
-- a task/todo list for decomposing long work;
-- isolated, synchronous subagents that receive a detailed task and return one
-  report; their task-tool documentation explicitly calls each invocation
-  stateless;
-- remote asynchronous subagents that persist `task_id`, remote `thread_id`,
-  `run_id`, status, and timestamps in agent state, then support check, update,
-  cancel, and list operations; and
-- conversation compaction that offloads old messages to a per-thread markdown
-  history file before summarization.
-
-The remote-task record is an especially useful shape for MiniOrk's parallel
-lanes: every dispatched item should carry a durable ID, owner, attempt,
-location, status, timestamps, and result reference. But DeepAgents' task state
-is a tracker around a remote service; it is not an exactly-once execution
-guarantee. MiniOrk still needs its own leases, fences, receipts, artifact
-manifests, and verifier gates.
-
-Conversation offload is a context-management technique, not an audit log.
-MiniOrk should keep manifests, verifier results, decisions, receipts, and
-promotion evidence in canonical structured storage. A model-facing summary may
-point to that evidence, but must not replace it.
-
-## What MiniOrk already does well
-
-The current implementation already encodes several lessons that are often
-missing when agents add “durability” late:
-
-| Existing MiniOrk mechanism | Why it matters | Primary code evidence |
-| --- | --- | --- |
-| Artifact-first checkpoint publication | Artifacts are hashed and fsynced before one SQLite transaction publishes the checkpoint and attempt record. Missing or altered artifacts fail closed on reuse. | `mini_ork/stores/checkpoints.py` |
-| Semantic checkpoint validity | Reuse checks the current input hash, recipe version, config hash, and manifest instead of treating “completed” as sufficient. | `db/migrations/0050_node_dag_checkpoints.sql` |
-| Selective DAG restart | `mini-ork recover <run_id> --from-node <id>` recomputes the rerun closure from that declared node rather than blindly rerunning everything. | `mini_ork/recovery/planner.py` |
-| Single-writer lease and fencing | An expired owner can be replaced, and a stale owner is rejected at checkpoint publication. | `mini_ork/stores/lease.py`, `db/migrations/0052_run_leases_recovery_requests.sql` |
-| Recovery idempotency and budget | Equivalent recovery requests converge on one record and dispatch is budget bounded. | `mini_ork/stores/lease.py` |
-| Effect receipts | A completed non-idempotent MiniOrk-owned tool call returns its recorded output on recovery rather than invoking again. | `mini_ork/stores/tool_receipts.py` |
-
-These are part of MiniOrk's differentiation. LangGraph, LangChain, and
-DeepAgents should inform the design, not displace the recipe-bound heterogeneous
-lanes, deterministic verifiers, artifact contracts, cost governance, or
-promotion gates.
-
-## The one important gap: exact historical checkpoint selection
-
-MiniOrk currently makes a strong **node-level** restart possible:
-
-```bash
-# Inspect a recovery plan without dispatching work.
-mini-ork recover <run_id> --from-node <node_id> --strategy pause
-
-# Run the recalculated closure after review.
-mini-ork recover <run_id> --from-node <node_id> --strategy resume
-```
-
-This is the correct operator interface for “start again from the reviewer” or
-“rerun implementation and all downstream verification.” It preserves the
-workflow topology instead of jumping into arbitrary agent code.
-
-However, `node_checkpoints` currently has one primary row per `(run_id,
-node_id)`. It records the latest reusable checkpoint for that node, while
-`node_attempts` preserves attempt observability. This makes current recovery
-safe, but it does not provide a first-class immutable **checkpoint revision**
-that an operator can select, compare, or fork.
-
-The resulting design target is:
-
-```text
-CheckpointRef = {
-  run_id, node_id, checkpoint_revision, parent_ref,
-  workflow_digest, recipe_version, config_hash, input_hash,
-  artifact_manifest_digest, verifier_summary, lease_fence
-}
-```
-
-An exact-resume request should require this reference (or a server-generated
-opaque ID), create a **new** recovery/fork run, and rerun that node's downstream
-closure. It must never mutate the original checkpoint or skip a verifier,
-promotion, scope, or human gate.
-
-```mermaid

-    Work->>DB: publish manifest only if fence is live
-    Work->>Gate: submit artifact and expected evidence
-    Gate-->>DB: verified pass or grounded failure
-```
-
-## Recommended path, in dependency order
-
-This extends the prior MiniOrk direction of Decision Checkpoints, structured
-lane resolution, leased work, recovery behaviours, and offline learning. It is
-deliberately additive.
-
-| Order | Change | Acceptance rule |
-| --- | --- | --- |
-| 1 | Emit a `DecisionCheckpoint@v1` at dispatch, recovery, escalation, verifier, promotion, and human-gate boundaries. Store the verifier state, failure class, allowed lanes/tools, capability health, remaining budget, selected action, reason, and expected evidence. | Every consequential routing action is explainable without reconstructing an LLM transcript. |
-| 2 | Preserve the existing node checkpoint as the current head, but add immutable checkpoint revisions and parent links. | An operator can inspect, select, and fork a specific revision; the original history is never overwritten. |
-| 3 | Generalise the current run lease into durable leased work items for parallel lanes. Require an artifact manifest and relevant verifier gate before completion can publish. | Expired work is recoverable; a stale worker cannot publish; duplicate completion is rejected. |
-| 4 | Make `LaneResolutionPolicy` a pure function that returns a structured decision rather than a lane string. Keep recipe-pinned heterogeneous lenses immutable unless an explicit policy permits a change. | The same checkpoint context yields the same decision; changing a lens is auditable. |
-| 5 | Define a small, authored recovery library: reproduce, inspect, narrow scope, safe tool retry, replan, stronger lane, and human gate. | Recovery actions are evaluated and verifier-grounded before any learning signal uses them. |
-| 6 | Only after the event and recovery data are reliable, evaluate routing offline. Use actions such as continue, tool, cheap lane, replan, stronger lane, and user interrupt. | The reward is verified information gain minus cost, latency, and interruption burden; learning cannot bypass the gates above. |
-
-## Resilience rules worth keeping explicit
-
-1. **A checkpoint is reusable only if the current inputs and evidence still
-   match.** Hash mismatch, recipe/config drift, absent artifact, or failed
-   verifier means rerun.
-2. **A lease is not a lock.** It expires; every publish must check the current
-   fence token. Lease acquisition alone cannot protect a late worker.
-3. **Retry by failure class.** Retry provider throttling and transient reads;
-   do not automatically retry an unclassified write, a scope violation, or a
-   failed verification.
-4. **Human decisions are durable artifacts.** Store the reviewed action,
-   allowed edits, decision, reviewer identity when available, and the exact
-   checkpoint they approved. Resuming should consume that artifact, not ask a
-   different question because the prompt changed.
-5. **Use summaries for context, not proof.** Summaries can guide a model to
-   manifest or verifier evidence; they cannot become the source of truth.
-6. **Do not learn from unverifiable success.** A model output, completed
-   process, or self-report is not a positive reward until the relevant
-   deterministic verifier and publication gates succeed.
-
-## What not to adopt
-
-- Do not replace MiniOrk's recipe, artifact, verification, and promotion model
-  with a general-purpose graph library.
-- Do not treat SQLite WAL as a multi-host coordination solution. Its local
-  single-writer discipline is valuable; distributed workers need a suitable
-  durable coordination store.
-- Do not automatically retry side effects just because an exception appears
-  transient. The safe prerequisite is an idempotency key or a completed receipt.
-- Do not let a selected historical checkpoint bypass new scope, verifier,
-  publication, promotion, or human gates.
-- Do not claim that MiniOrk can replay every provider-internal tool call. The
-  current receipt seam correctly covers MiniOrk-owned node-boundary effects;
-  opaque provider tool loops need a separate interception contract.
-
-## Existing verification seams
-
-The following focused tests already capture the important current guarantees
-and should remain part of the acceptance suite for future extensions:
-
-- `tests/test_recovery_closure.py` — reuse, invalidation, and `--from-node`
-  closure calculation;
-- `tests/test_lease_fencing.py` and `tests/test_recover_lease_wiring.py` —
-  one live recovery and rejection of stale checkpoint publication; and
-- `tests/test_tool_receipts.py` — replay does not invoke a completed
-  non-idempotent action twice.
-
-For immutable revisions and work-item leases, add equivalent tests for exact
-revision selection, parent-lineage preservation, rejected stale completion,
-and a recovery fork that cannot promote an unverified result.

-# Synthesis — Is mini-ork actually intelligent?
+# Research Synthesis — GEPA `promptEvolution/` → Prompt-Harness Migration
 
-**Run:** `run-1783718682-45995`
-**Question:** Which decision + learning mechanisms are INTELLIGENT (close a read-write loop from past runs) versus NOT-INTELLIGENT (static config, write-only tables, dead code)? Direct answer to the COMPOSER / interleaved-runs feature-isolation question.
-**Date:** 2026-07-10
-**Scope:** `bin/mini-ork*`, `lib/*.sh`, `mini_ork/**`, `recipes/**`, `config/**` at HEAD of `feat/gepa-gradient-fixes`.
+**Research question:** Should the `server/services/promptEvolution/` arc (GEPA mutation, reflection, VISTA gates, judge rubric, balanced-eval) migrate onto the mandatory project prompt harness (`registerPrompt` + `resolvePromptForDocument`, 3-tier `document → user → default` override chain)? If so, by what strategy, with what call-site→PromptKey mapping, what cache-key invariant, and what machine-checkable Definition-of-Done?
 
-Lens sources (read in full before composing):
-- `lens-glm.md` — breadth surface-scan (54 static sites, 11 DB tables tagged LIVE/WRITE-ONLY/DEAD)
-- `lens-kimi.md` — methodological rigor (6 closed-loop criteria, per-loop verdict table, 18 arxiv citations)
-- `lens-codex.md` — code-pattern survey (11 public frameworks, comparative table)
-- `lens-opus.md` — deep narrative (composer-question end-to-end trace)

-
-## 1. TL;DR
-
-- **★ Three genuine INTELLIGENT loops**, but only one is load-bearing for routing. GRPO lane routing (write→read symmetry, credit-assigned, decay-aware), gradient→context/role-evolver feedback, and within-run GEPA Pareto search. *(GLM-7 + Kimi-1+2+5; high confidence.)*
-- **★★ Three structurally correct mechanisms collapse toward STATIC in practice** because of reward starvation and a 3-sample floor. The lane router clears 5 of Kimi's 6 criteria on paper but degrades to noise-dominated at the floor; the explore rule never converges (constant ε-greedy); the reward rail silently NULLs on most runs. *(GLM-9 + Kimi-3+4.)*
-- **★★ At least five DB tables look like memory but aren't consulted**: `emergent_patterns`, `prompt_win_rates`, `conductor_decisions.outcome/realized_score`, `run_artifact_edges`, plus the WRITE-ONLY reflection chain (`gradient_records`/`pattern_records` w.r.t. routing). *(GLM-12 + Kimi-6.)*
-- **★★ Composer / interleaved-runs verdict: MIXED-WITH-LIMITS leaning GLOBAL-POLLUTED under default env.** `objective_domain="code-delivery"` is the universal default; `code_region` collapses feature dirs to top-level directory; `context_prior_runs_md`, `topology_win_rates`, `prompt_win_rates` all pool on `task_class` alone. Opt-in feature isolation is theoretically possible via `MINI_ORK_OBJECTIVE_DOMAIN=<feature>` but undocumented. *(Kimi-7 + Opus-3+4; high confidence.)*
-- **★ No public framework closes the full outcome→policy loop** — every one of the 11 surveyed (LangGraph, AutoGen, OpenHands, SWE-agent, MetaGPT, AutoGPT, Letta, Mem0, LlamaIndex, Agno, CAMEL) persists state or memory but none automatically turns graded outcomes into changed routing/prompt/topology. Mini-ork is not behind the field here, but it is also not ahead — closing this gap would be a genuine contribution. *(Codex-5 + Kimi-1.)*
+**Headline:** All four lenses converge that the migration is correct *and* that the naive reading of the kickoff premise is wrong. The kickoff says "43/44 files emit inline prompt literals"; the codex lens, reading live at HEAD, found that **only 10 of 50 non-test files actually call an LLM, 9 of those carry inline literals, and exactly 1 (`adversarialDrill.ts`) already registers** (Codex-A6). The migration backlog is **9 call-sites, not 43 files.** The single most important design finding — agreed by codex and opus, anticipated by glm and kimi as a gap — is that **GEPA mutation *candidates* are data and must NOT get a PromptKey; only the *meta-prompts that drive evolution* (reflector, judge, repair, rubric) are config and migrate.**

-## 2. Consensus findings (sources agree)
-
-Items where ≥2 lenses converge. ★ = 2-lens, ★★ = 3-lens, ★★★ = 4-lens.
-
-### ★★ GRPO lane routing is the only adaptive decision-maker (GLM-1 + Kimi-1)
-
-`agent_performance_memory` ← writes from `lane_router.py:235-245` (EMA-blended `relative_advantage` with shrinkage, recency, defect penalty); `lane_*_advantage` ← writes from `lane_router.py:247-279`; `preferred_lane` ← reads at `lane_router.py:286-330`; `decide()` consumes at `mini_ork/steering/decision_service.py:284-287` and `lib/decision_service.sh:80-217`. Region→domain→global fallback (GLM-21, Kimi-1) gives graceful degradation. This is the closest thing to a closed loop in the repo. The Kimi verdict "INTELLIGENT but NOISE-DOMINATED at floor" is the more honest reading; GLM calls it "INTELLIGENT closed loop" without quantifying the floor's variance cost. Both agree: it is the only one.
-
-### ★★ Reward starvation is the structural failure mode of the learning rail (GLM-12 + Kimi-3)
-
-`compute_reward_g` (`mini_ork/trace_store.py:28-40`) writes NULL when anchor==0; `grade_run_reward` (`mini_ork/trace_store.py:195-223`) only fires when `rubric.json` exists. The lane router skips NULL rows (`lib/lane_router.sh:173-187`). GLM identifies the 3-level step function at `bin/mini-ork-execute:289-299` (`_mo_reward_from_status` maps to 1.0/0.0/0.5) as the weak link; Kimi calls out the rubric gate as the reason most runs never produce `reward_g`. Both converge: the rail is mathematically sound but practically starved.
-
-### ★★ Constant ε-greedy exploration cannot converge (GLM-8 + Kimi-4)
-
-`MO_LEARNING_EPSILON=0.10` default at `lib/decision_service.sh:121`, no decay schedule. Kimi cites Auer et al. 2002 and Langford & Zhang 2008 — constant ε ⇒ linear cumulative regret. GLM notes "10% of dispatches ignore the learned route forever, no anneal" as risk shape. Worse, Kimi surfaces that exploration is gated `if learned_route:` (decision_service.py:289-297) — cold slices never explore at all, so the system cannot bootstrap its first sample.
-
-### ★★ The reflection chain (`gradient_records`/`pattern_records`/`emergent_patterns`) is memory-as-staging, not memory-as-decision-input (GLM-12 + Kimi-5)
-
-GLM tags `gradient_records` LIVE for context_assembler (failure-mode injection) and role_evolver (proposals); `pattern_records` LIVE as input to `emergent_patterns` promotion; `emergent_patterns` WRITE-ONLY (no consumer in routing/decision/context paths). Kimi calls the chain "WRITE-ONLY w.r.t. routing" — intelligent as memory substrate, not as a closed loop. Both agree: this is the largest gap between "the system looks reflective" and "reflection changes routing."
-
-### ★★ Composer / interleaved-runs feature isolation is nominally supported but in practice global-polluted (Kimi-7 + Opus-3+4)
-
-Kimi's formal analysis: `lane_router`'s region and domain tiers DO carry `objective_domain` end-to-end, so feature isolation is *theoretically* achievable. But (a) `objective_domain` defaults to `"code-delivery"` (`bin/mini-ork-execute:352`); (b) `code_region` collapses feature dirs to top-level directory (`bin/mini-ork-execute:1665-1737`, `_mo_infer_trace_code_region`); (c) `context_prior_runs_md` (`lib/context_assembler.sh:457-469`), `topology_preferred` (`lib/topology.sh:127-136`), `rho_top_prompts` (`lib/rho_aggregator.sh:108-111`) all pool on `task_class` alone. Opus's narrative trace says "MIXED-WITH-LIMITS leaning GLOBAL-POLLUTED under default env." Both lenses reach the same verdict via different paths.
+## Section 1 — TL;DR
 
-### ★★ Every cross-run learning surface except lane routing is keyed on `task_class` alone (Opus-3 + Kimi-7)
-
-`context_prior_runs_md`, `topology_preferred`, `rho_top_prompts`, GRPO grouping at `bin/mini-ork-execute:651` (`(node_type, task_class)`), agent_performance_memory global fallback (no `objective_domain` predicate, `lane_router.py:319-327`). The shared assumption is "task_class is the transfer boundary" — Kimi reads this from the SQL predicates; Opus reads it from the architectural commentary in `docs/architecture/techniques-compendium.md:121`. Both agree this is the load-bearing assumption and both agree it is contested in the literature.
-
-### ★ Static values dominate the decision surface (GLM-1..54 + Kimi-7+8)
-
-54 entries in GLM Catalog A; Kimi singles out reward starvation and constant ε as structural. The convergence: every per-run decision input that is *not* derived from prior traces is hardcoded somewhere (model names, fallback chains, reward weights, sample floors, budget caps, classifier keywords). GLM identifies a critical dual-edit hazard: `lib/process_reward.sh:99` and `mini_ork/learning/process_reward.py:55` mirror the same weights; `lib/lane_router.sh:87-90` and `mini_ork/lane_router.py:35-38` mirror the same hyperparameters.
-
-### ★ No public framework closes the full outcome→policy loop (Codex-5 + Kimi-1)
-
-Codex surveyed 11 frameworks; zero deliver "outcome/eval → credit assignment → policy/prompt/topology selection → future run." The dominant public pattern is **CLOSED context-state** (memory injection into next prompt) or **PERSISTENCE-ONLY** (durable state for human inspection). Kimi cites Shen et al. 2026 [arxiv:2606.16733] as the formal grounding for why write-read symmetry is the persistence half of any RL guarantee. Convergence: the field has not solved this problem either; mini-ork's GRPO loop is *one* of the few actually-attempted closures.
-
-### ★ Within-run intelligence ≠ cross-run intelligence (Kimi-5 + Codex-6)
-
-Kimi: GEPA's Pareto front is intelligent within one optimize run but rebuilt each run (gepa.py:62, no cross-run archive). Codex: "Within-run closure is kept separate from cross-run reuse. LangGraph closes resume/replay; SWE-agent closes reviewer/retry; AutoGPT records node execution. Those loops improve reliability without implying that run N learns a policy from runs 1..N-1." This is the most important conceptual distinction in the audit.
-
-### ★★ The reward signal is too coarse to discriminate at feature granularity (Opus-4-C + GLM-12)
-
-PRM weights at `lib/process_reward.sh:1-20` and `mini_ork/learning/process_reward.py:55-61` are a hardcoded 0.40/0.20/0.10/0.15/0.10/0.05 linear blend over trace observables. Opus Case C: a composer run that shipped a regression is indistinguishable from a clean run as long as `status=success`. GLM: the 3-level `_mo_reward_from_status` map collapses nuanced verdicts. Skalse et al. 2022 [arxiv:2209.13085] (reward hacking) is Opus's theoretical anchor. Both agree: the reward rail cannot form the per-feature GRPO signal that would make isolation valuable.
-
-### ★ Public frameworks mandate composite scope; mini-ork makes scope best-effort (Codex-2 + Opus-6)
-
-Codex convergent pattern #1: "Identity-scoped state is the unit of continuity" (LangGraph thread_id, OpenHands conversation_id, Letta agent/block, Mem0 user/agent/run, Agno user, AutoGPT execution/parent). Opus recommendation #6: "make a bare `mini-ork run` inherit its parent run's `objective_domain` (via `MINI_ORK_PARENT_RUN_ID`) when the caller doesn't stamp one." Both lenses converge: scope should be a mandatory composite namespace, not a default-everything fallback.
+- **Migrate — but only the 9 meta-prompt call-sites, never the mutation candidates.** The candidate prompt body flowing through `vistaGate.ts:333` (`scorePrompt(promptBody, …)`) is GEPA *data*; registering it is a category error. *(Codex-A6 + Opus-§3/§7; high.)*
+- **Use branch-by-abstraction gated per-file by existing fixtures, not big-bang.** All four refactoring sources reject big-bang; opus prefers strangler-fig but concedes the repo's own per-file fixture gates + pre-prod posture make the call closer than dogma. *(GLM-Fowler + Opus-§4.3/§6 + Kimi-10; high on "not big-bang", medium on strangler-vs-BBA — see §3.)*
+- **The cache key for replayed eval/judge prompts must be a full prompt-content hash + version, never owner-keyed or position-truncated.** This is a live defect: `idempotency.ts:44` hashes only the first 200 chars, and GEPA edits are deliberately small/targeted — a mutation past char 200 collides to a stale result. *(Codex-A5 + GLM-PromptLayer-repro + Kimi-8/Kimi-9 + Opus-§4.1; high.)*
+- **Treat each eval/judge prompt as a measurement instrument, not a feature.** Judge wording alone shifts outcomes up to 24.2pp; semantically equivalent rewordings flip 25% of verdicts — a drifting un-versioned ruler inside a self-improving loop is a metrology failure. *(Kimi-3/Kimi-4/Kimi-5 + Opus-§1/§4.2; high.)*
+- **Definition-of-Done is a machine-checkable invariant cloned from the repo's existing `no-restricted-syntax` gate.** `eslint.config.mjs:333` already bans raw `fetch()` to provider URLs via an AST selector; clone it to flag a literal/template passed as `prompt:` to `llm.generate*` inside `promptEvolution/**`, plus a grep gate in `scripts/lint-critical-gates.sh`. *(Codex-A "invariant" + Opus-§6.4; high.)*

-## 3. Disputed findings (sources disagree)
-
-### Dispute 1 — Is the lane router "INTELLIGENT" or "EFFECTIVELY-STATIC"?
-
-**GLM position:** Tags the lane router as a **genuinely closed learning loop** in Catalog B "What is genuinely INTELLIGENT" (#1). The write→read symmetry is clean; region/domain/global fallback is in place; the only qualifier is the static reward rail feeding it.
-
-**Kimi position:** "INTELLIGENT but **NOISE-DOMINATED at floor**." The loop formally closes but the 3-sample floor combined with NULL-reward starvation makes the learned preference indistinguishable from sampling noise (He & Gu 2025 [arxiv:2503.12020]; Tang et al. 2025 [arxiv:2502.10985]). Effective verdict: the loop "degrades toward static for three compounding reasons" — reward starvation, noise at the floor, cold-start blindness.
+## Section 2 — Consensus findings (≥2 lenses converge)
 
-**Why they disagree:** GLM verified write→read symmetry by grep; Kimi applied a statistical-validity test to the same evidence. GLM's framing is structural ("does the loop close?"); Kimi's framing is operational ("does the loop's output drive a better-than-random decision?"). Both are correct on their own terms.
+**★★★ (all 4) — A prompt that scores/judges is a versioned measurement instrument, and inline literals are pure liability for it.**
+glm frames it as the field's WHY ("prompt versioning must account for non-deterministic LLM outputs", GLM-MLflow; reproducibility needs the exact prompt pinned, GLM-PromptLayer-repro: "69 papers audited, only 5 runnable, 0 fully reproduced"). kimi supplies the effect sizes (Kimi-4/Zhang 2026: judge wording shifts harmful-rate up to **24.2pp**, surface rewording up to **20.1pp**; Kimi-3/Yagubyan 2026: pairwise prefs flip **13.6%** avg, semantically equivalent prompts change majority outcome in **25%** of cases). codex shows the repo *already accepted* a reflective meta-prompt as a harness key (Codex-A3, the `prompt_deep_research_reflect` "P2-10 harness-bypass closure"). opus supplies the theory (Opus-§1: the 2023 LLM-as-judge arrival turned the eval prompt from documentation into an instrument). **This is the load-bearing justification for the entire migration.**
 
-**My judgment:** Kimi is more useful for a practitioner. The structural closure is necessary but not sufficient — a loop that closes but emits noise is not a learner in any operational sense. The correct reclassification is **INTELLIGENT (structure) / STATIC (de-facto outcome)**.
+**★★★ (all 4) — GEPA mutation candidates are DATA, not config; only the meta-prompts are config.**
+codex makes it concrete and falsifiable: `vistaGate.ts:333` passes the candidate-being-scored as `systemPrompt`; "any ADR recommendation that tries to register `promptBody` is unsound" (Codex-A6). opus elevates it to the central tension and names the carve-out verbatim (Opus-§3/§7: "the candidates flow through placeholders, the instruments flow through the registry"). glm flagged it as a literature gap ("no canonical treatment of self-evolving prompts vs static-config", GLM-gap-1/gap-6). kimi flagged the same as caveat #6 ("GEPA prompts are data, not static config… the harness may need an extension"). **Convergent across breadth, rigor, practice, and theory — the strongest signal in the synthesis.**
 
-**Additional evidence needed:** η² (variance explained) of the learned advantage after conditioning on `task_class`/`objective_domain`/`code_region`. Opus §5 sketches the experiment design; it can be run on existing `state.db` data without code changes.
+**★★★ (all 4) — Cache key for replayed eval prompts must be content-hash + version, not owner-keyed / not truncated.**
+codex localizes the bug (Codex-A5: `idempotency.ts:44` = `sha256(...:promptSnippet.slice(0,200))`, 5-min TTL; GEPA edits are "small and targeted" per `gepaReflector.ts:239` → post-char-200 mutation = identical key = stale replay). opus supplies the defense already in-repo (Opus-§4.1/§6.3: `semanticPromptCache.ts:92-93` already does SHA-256 `content_hash` discriminated by `embedding_model_version`) and the CACE framing (Sculley 2015). glm supplies the external recipe (GLM-PromptLayer-repro + GLM-FutureAGI: cache must include prompt content + version + model + temp + seed; GLM-2601.23088 key-collision attack → need ≥SHA-256 collision resistance). kimi supplies the determinism science (Kimi-8/Messina-Scotta 2026: `T_bg ≈ 0.075` even at nominal T=0 → key must include model+provider+version; Kimi-9/Li 2026: 480k calls, temp↔agreement Pearson −0.82 to −0.93 → freeze + record judge temperature).
 
-### Dispute 2 — Is `objective_domain` a feature isolation lever or a consumer bucket?
+> **Note — two distinct cache mechanisms, not a contradiction.** codex's `idempotency.ts` (a 5-min request-dedup middleware, truncated/owner-keyed = the *defect*) and opus's `semanticPromptCache.ts` (content-hash eval cache = the *correct* model). The ADR fix is: route eval/judge calls through the content-hash cache (or mark them idempotency-exempt), never let the 200-char middleware key a GEPA eval. See §3 for why this is reconciliation, not dispute.
 
-**Opus position (from migration `0042` + techniques-compendium.md:121):** The official framing is consumer identity — "code-delivery" vs "book-gen." Within "code-delivery," runs of different features pool. The renaming recommendation #1 ("rename the env var to reflect its dual role") is based on this reading.
+**★★ (codex + glm) — The universal registry schema is "name + version + label", and the gateway sits downstream of prompt resolution.**
+codex: researcher's `PromptKey` + A/B variant + doc/user override mirrors Langfuse `getPrompt(name, version, {label})` (Codex-B1), promptflow filename (Codex-B3), Helicone/PromptLayer (Codex-B6); the `llm.generateStructured` facade takes a raw string, so migration swaps the literal *upstream* of the facade, never touches the facade (Codex-A4/convergent-pattern-2). glm: same triad across Langfuse/LangSmith/Helicone/MLflow (GLM-bucket-1), and prompt-as-flag-payload is a documented rollout pattern (GLM-GrowthBook/FeatBit). **Implication: the researcher harness already IS the convergent shape; the migration just enrolls 9 keys.**
 
-**Codex position (convergent pattern #1):** Identity-scoped state should be a *mandatory composite namespace* such as `(objective_domain, workflow_version_id, feature_id)`, not a single bucket. This implies `objective_domain` SHOULD serve as feature isolation if the user opts in.
+**★★ (opus + kimi) — Provenance must be recorded as a tuple per mutation cycle to defend against judge drift.**
+opus: record `(promptKey, source, content_hash, embedding_model_version)` so "by what standard was mutation X promoted?" is one query (Opus-§6.5). kimi: Preference Leakage (Kimi-7/Li 2025: PLS up to **37.9%**, p<0.001) + the alt-annotator test (Kimi-6/Calderon 2025) demand provenance separating judge lineage from generator lineage. RULERS (Kimi-5/Hong 2026) = "locked, versioned, immutable rubric bundles" with QWK 0.7276 vs 0.4319 — the academic blueprint for the registry's judge-rubric keys.
 
-**Why they disagree:** Opus is reading what mini-ork actually does (single bucket, consumer framing); Codex is prescribing what mini-ork should do (composite scope). Both are correct in their frame.
+**★★ (glm + kimi) — Co-version the eval set with the prompt; validate each variant before deleting the legacy literal.**
+glm: GLM-2601.22025 ("eval harness version-controlled alongside the prompt templates… small enough to run on every change"). kimi: same paper as Kimi-10/Commey 2026 — generic "improved" prompts dropped Llama-3 extraction **100%→90%**, RAG compliance **93.3%→80%**. **Direct support for per-file fixture-gated migration: each harness-registered replacement must pass the existing GEPA fixture before the inline literal is removed.**
 
-**My judgment:** The current implementation is the consumer-bucket design (Opus is right about the code). The codebase pattern that *would* make it a feature-isolation lever already exists in `lane_*_advantage` (Kimi-1+7) — the env var just isn't documented as such. The reconciliation: `objective_domain` is *technically* feature-isolated at the lane-router region/domain tiers, but the docs and the global fallback keep it consumer-bucketed in practice.
-
-**Additional evidence needed:** A scan of how many prior runs actually set `MINI_ORK_OBJECTIVE_DOMAIN` to a non-default value vs left it at "code-delivery." If <10%, the lever is dormant regardless of capability.
-
-### Dispute 3 — Are the WRITE-ONLY tables the right next thing to wire, or are they correctly dead?
-
-**GLM position (Catalog B):** `emergent_patterns`, `prompt_win_rates`, `conductor_decisions.outcome` are WRITE-ONLY — "the classic 'looks like memory, isn't consulted' case." Highest-leverage fix #1: read `conductor_decisions.realized_score` back into the conductor's predicted-score model.
-
-**Kimi position (criterion 1):** Write-only reflection rows are WRITE-ONLY but if wired back into routing without a judge gate, they risk "memory confabulation" (Dixit et al. 2026 [arxiv:2605.29463]). The recommendation is extract→distill→verify before any reflection row becomes a routing input.
-
-**Why they disagree:** GLM is identifying a closed-loop gap (read is missing). Kimi is identifying a correctness gap (if you just close it naively, you risk poisoning the rail with confident-but-wrong self-diagnoses).
-
-**My judgment:** Both are right. The fix order should be (1) build the extract→distill→verify pipeline (Kimi's safety argument), then (2) wire the verified rows into routing/context (GLM's closure argument). Naively closing the gap first is exactly the kind of self-poisoning failure mode that makes the audit worth doing.
-
-**Additional evidence needed:** A controlled test where promoted patterns are surfaced to one run group and withheld from another; compare downstream outcome variance to estimate whether the wiring would help or hurt.
+**★★ (codex + opus) — A fallback literal survives even in a "no-inline" system; the invariant forbids the *live* literal, not all strings.**
+codex-convergent-pattern-3 (researcher `fallbackPrompt`, Langfuse `fallback=`) + Opus-§6.4 carve-out ("forbid literal *templates* while allowing placeholder-injected mutation content"). **The lint gate must be written to this precision or it false-positives on GEPA's raison d'être.**

-## 4. Cross-lens gaps (what's NOT in any source)
-
-Items the lenses collectively did NOT investigate or answer. Candidates for future research:
-
-1. **η² for feature after task_class is controlled** (Opus §5 sketched this; nobody ran it). Without it, the entire feature-isolation debate is unresolvable in principle.
-2. **Realized-score regression.** GLM identified the missing edge; nobody has measured how much variance in conductor accuracy would be explained by `realized_score` regressed onto the predicted-score model's `0.3` gain.
-3. **Eval-node rollout.** The eval-after-verify node from `internal-docs/research/2026-07-03-adding-eval-to-miniork-run-flow.md` would solve the reward-starvation problem by guaranteeing a graded `reward_g` on every run. Nobody estimated the eval-cost-per-run vs the variance-reduction payoff.
-4. **Empirical shrinkage.** Adaptive sample-floor (Opus recommendation #5) with empirical-Bayes shrinkage. Theoretical benefit is clear; nobody benchmarked the cost in mini-ork's specific reward distribution.
-5. **Cross-framework GRPO audit.** Codex surveyed persistence/memory but did not check whether any framework has a similar GRPO-on-prior-outcomes loop. The closest is SWE-agent's within-run best-of-attempt — it is not cross-run.
-6. **Performance under non-stationary task mix.** Kimi cited Tang 2025 on Elo/BT misspecification but did not measure how mini-ork's diff-in-means advantage degrades when the lane population shifts (e.g., adding a new lane to the family).
-7. **`MINI_ORK_PARENT_RUN_ID` lineage propagation.** Opus recommendation #6 notes the write sites but no lens tested whether parent→child inheritance actually works end-to-end in the recursive spawn path.
-

-
-## 5. Numbered recommendations
-
-What a thoughtful practitioner should DO with this synthesis today. Each item: action, supporting lenses, condition under which it would be wrong.
-
-1. **Promote `emergent_patterns` (status='proposed'→'approved') into `context_assembler`'s failure-mode injection path.**
-   - Lenses: GLM-12 (highest-leverage #2), Kimi-3 (criterion 1 fails today)
-   - Wrong if: pattern promotion has no judge-gate; the patterns could be confidently-wrong self-diagnoses (Kimi §6 caveat; Dixit 2026 [arxiv:2605.29463]).
-   - Pre-condition: build extract→distill→verify pipeline first, then wire.
+## Section 3 — Disputed findings (sources disagree)
 
-2. **Read `conductor_decisions.realized_score` back into the conductor's predicted-score model** (replace fixed `0.3` gain with fitted/EMA coefficient).
-   - Lenses: GLM-12 (highest-leverage #1), Opus §4 case A (interleaved-runs pollution requires the conductor to self-correct)
-   - Wrong if: the predicted-score model is dominated by topology/lane-advantage terms that overwhelm the realized-score signal — measure first.
-   - Source: write at `bin/mini-ork-conductor:248-256`; current reader is only `scripts/smoke-learning-loops.sh:142`.
+**Dispute 1 — Strangler-fig vs branch-by-abstraction as the chosen strategy.**
+- **opus argues strangler-fig** (Opus-§6.1): wrap each call-site behind `resolvePromptForDocument` one file at a time, gated by its fixture, highest-stakes (judge rubric) first. Cites Fowler 2004 + Feathers 2004.
+- **opus simultaneously concedes branch-by-abstraction** may win "if the 43 files share so much state that no single file can be migrated without its neighbors" (Opus-§6.1) and that **pre-prod posture makes big-bang itself more tenable than dogma suggests** (Opus-§6.6).
+- **glm leans branch-by-abstraction** on structural grounds: "the GEPA migration has no HTTP façade — it's an internal service-layer refactor — so branch-by-abstraction may fit better than strangler-fig" (GLM-bucket-3, citing Fowler's *Patterns of Legacy Displacement* + *LegacySeam*: `resolvePromptForDocument` IS the seam).
+- **codex implicitly favors a precedent-extension** (not a named refactor school): replicate the P2-10 closure that already added a reflective key (Codex-A3) — i.e. the pattern is proven in-repo, lowering the risk of any sequencing choice.
+- **My judgment:** This is a *scale* disagreement, not a contradiction. Strangler-fig is for replacing a *system* at its edges via a façade; there is no façade here — `resolvePromptForDocument` is an internal **seam** (GLM-LegacySeam), which is the textbook trigger for **branch-by-abstraction**. But the migration is only **9 call-sites**, not 43 files (Codex-A6) — small enough that the strangler/BBA distinction nearly collapses. **Resolution: branch-by-abstraction is the technically precise label (seam, no façade, in-place swap), executed per-file gated by existing fixtures (the strangler discipline opus wants).** The ADR should pick **branch-by-abstraction**, name strangler-fig and big-bang as alternatives-rejected, and note the choice is low-stakes given the 9-site backlog. *Additional evidence that would resolve it fully: the call-site shared-state graph (does any of the 9 sites share mutable module state with another?) — codex's census suggests they don't, but the impl run should confirm before committing to per-file ordering.*
 
-3. **Run the η² experiment from Opus §5 on existing `state.db` data** before investing in feature-scoping infrastructure. SQL-only, no code changes.
-   - Lenses: Opus §5 (full design), Kimi-7 (the formal reading), GLM-7 (region advantage write site)
-   - Wrong if: the experiment is run on rows that pre-date the `objective_domain` column (migration `0042`); restrict to post-migration rows.
-   - Pre-condition: filter to post-2026 rows where `objective_domain IS NOT NULL`.
+**Dispute 2 — Is the kickoff's "43/44 inline literals" premise accurate?**
+- **Planner/kickoff premise:** 43/44 files emit inline literals (audit Bundle A: G-5/G-6/K-9/K-10/D-6/Opus-Seam-A).
+- **codex, reading live at HEAD (Codex-A6):** 50 non-test files; **10 call an LLM; 9 carry inline literals; 1 already registers.** "True compliant count is 1 of 50."
+- **My judgment:** Not a real contradiction — different denominators. The audit counted *files containing literal strings*; codex counted *files that actually invoke an LLM with a literal as the live prompt*. The migration-relevant number is codex's: **9 call-sites**. The ADR must use 9 (the actionable backlog) and footnote the 43 (the broader literal-sprawl the audit flagged, most of which are non-LLM strings or comments). *Resolving evidence: codex already cites file:line for all 9 (census table) — verifier should confirm each anchor resolves.*
 
-4. **Replace `_mo_reward_from_status` (3-level step function at `bin/mini-ork-execute:289-299`) with a graded signal** OR guarantee the eval node populates `reward_g` on every run.
-   - Lenses: GLM-12 (Catalog A #12), Kimi-3 (reward starvation), Opus Case C (reward-source coarseness)
-   - Wrong if: the eval node is too expensive per-trace or its reward is noisier than the PRM; cost-benefit must be measured first.
-   - Source: Skalse et al. 2022 [arxiv:2209.13085] on reward hacking (Opus-4-C).
+**Dispute 3 — Does the harness override chain *fit* self-evolving prompts at all, or does it need an extension?**
+- **kimi (caveat #6) + opus (§3) say the 3-tier chain is INERT for GEPA:** a system-authored prompt has no "user override of default"; forcing `userUuid:"system"` collapses four tiers to default-only ("theater", Opus-§3).
+- **opus's conclusion (§6.2) — add a `system`/`evolved` source tier** that bypasses `document→user` resolution; cites that the `source` enum already carries a non-user value (`label`, `promptIntegrationService.ts:181`) proving the tier set is extensible.
+- **codex implicitly says no extension needed for the meta-prompts:** they ARE human-authored config (the reflector/judge/repair templates), so the existing default tier fits; only candidates are data, and candidates don't migrate (Codex-A6).
+- **My judgment:** Both are right about different objects. **Meta-prompts (the 9 sites) = human-authored config → existing default tier fits, no extension required.** The `system` tier opus proposes is only needed *if* the team ever wants to persist an *evolved* prompt as a reusable canonical default (glm-gap-6's (a)+(b): persist/share mutation output). That is **out of scope for this migration** (which governs instruments, not candidates). **Resolution: the ADR migrates the 9 meta-prompts using the existing 3-tier default; it explicitly defers the `system`/`evolved` tier as a documented future extension, with opus's Kendall-τ experiment (§ below) as the gate for whether it's ever needed.** This is the cleanest reconciliation of the dissent: opus is right the chain is inert for *candidates*, wrong that this blocks *instrument* migration.
 
-5. **Document `MINI_ORK_OBJECTIVE_DOMAIN` as a feature-scoping lever** and make the default-on recursive path inherit parent_run_id → objective_domain automatically.
-   - Lenses: Opus §6 recommendation #1+#6, Kimi-7 (the lever exists, just dormant), Codex convergent pattern #1 (composite scope)
-   - Wrong if: η² experiment (recommendation #3) shows feature explains <5% of reward variance — then the lever is structurally useless.
-   - Source: write sites at `bin/mini-ork-spawn:113,123`, `recipes/doc-to-features-loop/lib/per_feature_dispatcher.py:422`; default at `bin/mini-ork-execute:352` and `mini_ork/trace_store.py:125`.
-
-6. **Reconcile the dual-source-of-truth hazards** — three `$50/day` literals (`config/agents.yaml:57`, `bin/mini-ork-conductor:48`, `lib/llm-dispatch.sh:1377`) and two PRM weight tables (`lib/process_reward.sh:99`, `mini_ork/learning/process_reward.py:55`).
-   - Lenses: GLM-1 + GLM-2 + GLM-27 + GLM-39 + GLM-43 (dual-edit hazards)
-   - Wrong if: the literals are intentionally different (e.g., per-pipeline budget vs global); if so, add a comment explaining.
-   - Pre-condition: verify the values are meant to match before consolidating.
-
-7. **Add adaptive sample floor** (empirical-Bayes shrinkage for thin slices) rather than moving the static floor.
-   - Lenses: Kimi-3 (criterion 2 marginal), Opus §6 recommendation #5
-   - Wrong if: shrinkage adds complexity but the underlying signal is dominated by static heuristics anyway (η² small per recommendation #3).
-   - Source: Efron & Morris 1975 (shrinkage theory).
+> **Per recipe discipline (Nasser 2026): disputes above are reported, not vote-ruled.** Where I render a "resolution" it is a *reconciliation* (the lenses describe different objects/scales), not a majority vote between same-conviction agents.

-## 6. Direct answer to the COMPOSER / interleaved-runs question
+## Section 4 — Cross-lens gaps (in no source)
 
-**Verdict: MIXED-WITH-LIMITS — leaning GLOBAL-POLLUTED under default env.**
+1. **No canonical "self-evolving prompt vs static-config prompt" treatment.** Every registry vendor (Langfuse/LangSmith/Helicone/MLflow) and academic source assumes human-authored prompts. The GEPA data-vs-config carve-out is constructed from first principles here (GLM-gap-1, Kimi-caveat-6, Opus-§3). *Candidate for: an in-repo ADR contribution + possible upstream note to GEPA authors.*
 
-Three regimes, in order of likelihood for real usage:
+2. **No published cache-key composition spec for LLM eval replay.** All sources gesture "pin everything"; nobody publishes the canonical recipe. The ADR must *invent* the composite: `sha256(canonical_json{prompt_content, prompt_version, model_id, provider, temperature, seed, parser_schema})` — flagged as an ADR contribution, not established practice (GLM-gap-2, corroborated by Kimi-8/Kimi-9 on which fields are load-bearing).
 
-- **Default (`MINI_ORK_OBJECTIVE_DOMAIN` unset):** **GLOBAL-POLLUTED.** All runs stamp `objective_domain="code-delivery"` (`bin/mini-ork-execute:352`, `mini_ork/trace_store.py:125`). `lane_domain_advantage`/`lane_region_advantage` pool across every eng-team run; `context_prior_runs_md` filters on `task_class` alone; `topology_preferred` and `rho_top_prompts` likewise. The only partition is `code_region` = top-level directory of `files_written[0]` (`bin/mini-ork-execute:1665-1737`), which collapses `src/composer` and `src/auth-middleware` to a shared key. Maximum effective continuity = the sample floor (3 runs) IF the composer's exact `(task_class, node_type)` triple clears it; otherwise global fallback.
+3. **No strangler-vs-BBA case study for an internal prompt-registry call-pattern migration.** Fowler's canon is application rewrites, not internal registry enrollment (GLM-gap-3). The ADR's branch-by-abstraction choice needs original justification (the seam argument), not just a citation.
 
-- **With `MINI_ORK_OBJECTIVE_DOMAIN=composer` explicitly exported:** **MIXED-WITH-LIMITS.** Region and domain slices (`lib/lane_router.sh:511-545`) DO carry composer identity into `lane_domain_advantage` / `lane_region_advantage`. But `context_prior_runs_md` (planner context), `topology_preferred` (recipe selection), and `rho_top_prompts` (prompt selection) still ignore the domain — those stages remain feature-blind. Effective feature memory reaches ~3 runs of continuity on lane routing alone, with cold-start on every fresh `(task_class, node_type)` pair.
+4. **No public OSS "no-inline-prompt-literal" lint rule.** The seam canon says "wrap then enforce" but no project publishes the regex/AST rule (GLM-gap-4). The repo's `no-restricted-syntax` clone (Codex-invariant) is novel practice worth documenting.
 
-- **With the audit recommendations implemented** (rec #1, #3, #5): Theoretically **FEATURE-ISOLATED** at the lane-routing layer and the planner-context layer, with adaptive shrinkage smoothing cold starts. Empirically untested.
+5. **No third-party empirical data on prompt-regression incidents caused by implicit vs explicit prompt-source.** Vendors *sell* "you need a registry"; the closest evidence (GLM-PromptLayer 69-paper audit) is about academic eval reproducibility, not prompt-source hygiene (GLM-gap-5). **Verifier must not over-claim external validation for the lint-invariant recommendation** — it rests on in-repo reasoning + analogy, not measured incident data.
 
-**Maximum effective continuity for one feature over N runs:** 3 runs under default (sample floor); 3 runs with explicit domain stamping (because non-lane stages remain polluted); N runs if the audit's recommendations are implemented and η² confirms the signal exists.
+6. **No accuracy anchor in the judge-reliability literature.** Kimi-caveat-2: Zhang/Yagubyan show prompts *disagree* but rarely establish which is *correct*. **So the migration's honest claim is improved *reproducibility + auditability*, NOT improved accuracy.** The ADR must state this scope limit explicitly.
 
-**Confidence:** High on the structural verdict (all 4 lenses converge on the read-site analysis). Medium on the operational "what users actually experience" because no lens measured real-world distribution of `MINI_ORK_OBJECTIVE_DOMAIN` values across prior runs.
+7. **Open question opus would measure (the OOD experiment):** *Does routing GEPA eval/judge prompts through the harness change the fitness ranking of mutations, holding content byte-identical?* Measurable = Kendall's τ between pre/post-migration mutation orderings. τ≈1.0 → harness is free auditability, migrate. τ<1.0 → harness leaks into the fitness signal (stray placeholder default, Tier-0 A/B firing on a system key, cache-key mismatch) → seal leaks first (Opus-§5). **This is the single best validation experiment for the impl run.**

+4. **Make the eval/judge cache key a full content-hash + version, never owner-keyed or 200-char-truncated.** Route GEPA eval/judge through `semanticPromptCache.ts` (content-hash, already correct) and mark those calls exempt from `idempotency.ts`'s 200-char middleware. *Support: Codex-A5 (the bug) + Opus-§4.1/§6.3 (the in-repo defense) + GLM-2601.23088 (≥SHA-256) + Kimi-8/Kimi-9 (include model+temp).* **Wrong if:** GEPA eval results were ever legitimately user-specific — they measure the prompt, not the user.

-- Combines the four lenses; no new external citations introduced.
-- Recommendation #3 design follows Opus §5 exactly; #1 follows GLM-12 with Kimi §6 caveat applied; #5 follows Opus recommendations #1+#6 with Kimi-7 + Codex convergent pattern #1.

+5. **Ship the machine-checkable DoD invariant** = clone `eslint.config.mjs:333` (`no-restricted-syntax`) to flag a `Literal`/`TemplateLiteral` passed as the `prompt:` property of an `llm.generate*` CallExpression inside `server/services/promptEvolution/**`, **plus** a grep gate in `scripts/lint-critical-gates.sh`: `! grep -REn 'prompt:\s*` + backtick `|const \w*[Pp]rompt\w* = ` + backtick + `You are' server/services/promptEvolution --include='*.ts' | grep -v '\.test\.'`. Green = zero inline literals remain. *Support: Codex-invariant + Opus-§6.4.* **Wrong if:** written too coarsely — it must forbid literal *templates* while allowing placeholder-injected candidate content (the §2 carve-out), or it false-positives on GEPA's own data path.

+6. **Record `(promptKey, source, content_hash, embedding_model_version)` as a provenance tuple per mutation cycle.** *Support: Opus-§6.5 + Kimi-5/Kimi-7 (judge drift/leakage).* **Wrong if:** per-cycle storage cost exceeds audit value — implausible at 5 mutations/cycle (`gepaReflector.ts:24`).

-### B.2 WRITE-ONLY (rows produced and counted, no decision reads them)
-
-| # | table | write site | why it's not consulted |
-|---|-------|-----------|------------------------|
-| 1 | `emergent_patterns` | `lib/reflection_pipeline.sh:396-437` (status='proposed') | no `SELECT … emergent_patterns` in routing, decision, or context_assembler paths (GLM-12) |
-| 2 | `prompt_win_rates` | `lib/rho_aggregator.sh` / `mini_ork/learning/rho_aggregator.py` | only `rho_top_prompts` + lifetime reporting; `bin/mini-ork-conductor:9` *claims* to read it but body queries only `topology_win_rates` + `agent_performance_memory` (GLM-12, header is stale) |
-| 3 | `conductor_decisions.outcome` / `realized_score` | `bin/mini-ork-conductor:248-256` | only `scripts/smoke-learning-loops.sh:142` (asserts `success:1.0`); conductor's predicted-score model never regresses on it |
-| 4 | Reflection chain (w.r.t. routing) | `lib/gradient_extractor.sh:57`; `lib/reflection_pipeline.sh:266`; `bin/mini-ork-reflect:301,184`; `bin/mini-ork-metrics:105` | readers are UI counts (`mini_ork/web/routes/trajectory.py:170`, `run_detail.py:295,310,375`) + tests; no `decide()`/`lane_router` reader by key (Kimi-5) |
-| 5 | `bug_reports` (emission half) | `lib/bug_report.sh` + `bin/mini-ork-bug-collector` (regex/severity/confidence) | ingestion is LIVE; emission is regex heuristic (same shape as `mini_ork-classify`), precision bounded by hand-written patterns |

-
-| # | table | write site | why it's dead |
-|---|-------|-----------|---------------|
-| 1 | `run_artifact_edges` | insert site exists | grep across `*.sh` + `*.py` returned zero non-test readers (GLM-12); also absent from context_assembler, conductor, lane_router, web routes |
-
-### B.4 NOT-INTELLIGENT veneer (looks intelligent but isn't)
-
-| # | mechanism | file:line | why it isn't |
-|---|-----------|-----------|--------------|
-| 1 | `coalition_ok` field in `decide()` return | `mini_ork/steering/decision_service.py:123-197` | computed AFTER `route` is fixed at `:287`; output-only diagnostic, not a decision input |
-| 2 | `reward_summary` field in `decide()` return | `mini_ork/steering/decision_service.py:200-262` | same — computed after route is fixed; no external caller branches on it |
-| 3 | `cost_pause` sidecar | `mini_ork/dispatch/cost_pause.py:24-57` | self-read same run only; within-run accounting, not cross-run learning |
+8. **Run opus's Kendall-τ pass-through experiment in the impl run** as the migration's correctness gate, and **defer the `system`/`evolved` source tier** unless τ<1.0 forces it. *Support: Opus-§5/§6.2 + Kimi-caveat-6.* **Wrong if:** no historical mutation cycles with recorded fitness exist to replay (then fall back to byte-identical-render assertion per call-site).

-## Appendix C — Top 5 highest-leverage changes (in order)
-
-Synthesizing across all 4 lenses, ranked by combined structural + operational payoff:
-
-1. **Promote verified `emergent_patterns` into `context_assembler`'s failure-mode injection path.** Single biggest gap between "the system looks reflective" and "reflection changes routing." Pre-condition: build extract→distill→verify pipeline (Kimi §6 caveat). *(GLM-12 highest-leverage #2 + Kimi-5 + Opus-6 #4.)*
-
-2. **Read `conductor_decisions.realized_score` back into the conductor's predicted-score model** (replace the fixed `0.3` gain with fitted/EMA coefficient). The meta-orchestrator currently cannot learn from its own prediction error. *(GLM-12 highest-leverage #1 + Opus Case A.)*
-
-3. **Replace `_mo_reward_from_status` with a graded signal OR guarantee `reward_g` population via eval node.** Without this, the GRPO rail is starved; reward_g=NULL for most runs makes the lane router operate on a thin slice. *(GLM-12 highest-leverage #5 + Kimi-3 + Opus-6 #4.)*
-
-4. **Document `MINI_ORK_OBJECTIVE_DOMAIN` as a feature-scoping lever and have the recursive spawn path inherit parent_run_id → objective_domain automatically.** Makes the lever opt-in-by-omission rather than opt-in-by-discipline. *(Opus-6 #1+#6 + Kimi-7 + Codex convergent pattern #1.)*
-
-5. **Run the Opus §5 η² experiment on existing `state.db` data** before investing in feature-scoping infrastructure. SQL-only, no code changes. Resolves the entire "is feature-isolation worth building" debate with data. *(Opus §5 + Kimi-7 + GLM-7.)*

-# Harsh-critic panel verdict — ported executor + runtime cutover
-
-**Date:** 2026-07-08
-**Target:** `mini_ork/cli/execute.py` (`dispatch_node` + live path) under `MINI_ORK_RUNTIME=python`, vs bash `bin/mini-ork-execute`.
-**Panel:** two independent adversarial reviewers (opus, separate contexts), refute-or-promote discipline. Cross-vendor lanes (kimi/codex) were unavailable this run — this is a single-family (Anthropic) panel; a kimi/codex second pass is still advisable but the findings below are code-grounded, not judgment calls, so family diversity does not change them.
-**Gate #1 (live-dispatch harness):** PASS — a real sonnet dispatch through the ported live path called the LLM, wrote the artifact, charged cost $0.34, rc 0. The *wiring* is live; the *fidelity* is where the gaps are.
-
-## VERDICT: NO-GO on flipping the LIVE dispatch default.
-
-The deterministic surface (dry-run / plan / classify / init / review …) IS safe — the parity harness proves it and the default cutover for those is fine. The **live `dispatch_node` path** has 5 blocks-cutover defects. Bash must remain the live executor until they are fixed.
-
-## Blocks-cutover findings (each with a concrete trigger)
-
-| # | Defect | Port | Bash | Trigger → divergent outcome |
-|---|--------|------|------|------------------------------|
-| 1 | **Policy lane-routing is dead.** Port dispatches `lane = model_lane or node_type` raw; never calls the policy router. The entire GRPO/learning-governed routing loop is inert. | `mini_ork_execute.py:870,915` | `bin/mini-ork-execute:2219` (`dispatch_lane=$(_mo_policy_route_lane …)` before dispatch; default policy `learning_governed`) | Any researcher node, `model_lane` unset: bash dispatches the routed lane (e.g. `kimi_lens`/`opus_lens`); port dispatches `--node-type researcher`. **Wrong model invoked + core value-prop disabled.** |
-| 2 | **Publisher is a stub.** Just `set_status("published")`. No oracle gates, no panel-verdict requirement, no artifact-contract copy, no git commit. | `mini_ork_execute.py:1000-1002` | `bin/mini-ork-execute:2909-2998, 3059-3068` (4 oracle gates → `return 1` on `safety_violation`; panel-verdict gate; `_publisher_try_commit_files` / source_artifact→outputs copy) | code-fix recipe: implementer edits never committed. artifact recipe: output file never written. `safety_violation` from a panel: bash BLOCKS, port marks `published`. **Ships unsafe or empty, reports success.** |
-| 3 | **`is_synth` misclassifies the panel gate.** `"synth" in node_id` matches `tier4_synth`, which bash treats as a *panel approval gate*, not an ungated synth. | `mini_ork_execute.py:945,963-966` | `bin/mini-ork-execute:2704-2727,2799-2816` (`_is_panel_gate=1`, `_is_synth=0`, writes `panel-verdict.json`, runs the verdict gate) | recursive-validate-impl `tier4_synth` with verdict=reject: bash fails+rolls back; port returns `0/done` ungated AND writes `synthesis.md` not `panel-verdict.json` (so F2's publisher gate can't read it either). **Approval gate dead.** |
-| 4 | **`MO_TARGET_CWD` never pinned.** Port reads `MO_TARGET_CWD or os.getcwd()` but nothing derives/exports it from the kickoff's git toplevel. | `mini_ork_execute.py:930-933` | `bin/mini-ork-execute:2632-2642` (`export MO_TARGET_CWD=$(… git rev-parse --show-toplevel)`, the CWT-A corruption fix) | `MINI_ORK_RUNTIME=python bin/mini-ork run <recipe> <foreign-repo-kickoff>` from the mini-ork repo: `os.getcwd()`=MINI_ORK_ROOT, so codex runs there AND `apply_impl_output` git-applies into **mini-ork's own tree**. Reintroduces the known repo-corruption hazard. |
-| 5 | **Pre-dispatch gates absent.** No `.stop-requested`, intervention gate, capability assert, or stale-heartbeat watchdog. | `mini_ork_execute.py:864-908` | `bin/mini-ork-execute:2231-2236, 2258-2262, 2296-2318` | UI POSTs `/stop` mid-run: bash halts before next node; port ignores it, keeps spending budget. Node `requires_capabilities` a lane lacks: bash fails `config`; port dispatches anyway. **No soft-stop; incapable-lane dispatch.** |
-
-Degrade-only: **F6** synth artifact naming hardcodes `synthesis.md` ignoring `artifact_contract.source_artifact` (`:946-947`) → downstream reads a missing/stale file for non-default contracts.
-
-## Refuted (confirmed sound)
-
-- **No other silent-no-op entrypoints.** All 13 delegated `mini_ork_<x>.py` have working `__main__`; the ~80 helper modules lacking `__main__` are unreachable by the shim's `basename|tr '-' '_'` mapping. (init/review already fixed, PR #151.)
-- **Reviewer verdict string mapping is correct** — `_REVIEW_PASS`/`_REVIEW_REVISE`/fail+unknown→`verdict_fail` all match bash. It only breaks via the `is_synth` path (F3), not the string set.
-- **Shim arg/env/cwd forwarding is correct** (`exec env PYTHONPATH=… python3 -m … "$@"`; process replacement, no set-e interaction). Minor: unset `MINI_ORK_ROOT` silently stays bash (observability, not correctness).
-
-## Must-fix list before live cutover (ordered)
-
-1. Apply `_mo_policy_route_lane` (or the ported `learning_static_lane` + governed policy) before `dispatch_fn`, so the routed lane — not the raw node_type — reaches `--node-type`.
-2. Port the publisher: oracle gates (block on `safety_violation`), panel-verdict requirement, `_publisher_try_commit_files` + source_artifact→outputs copy.
-3. Fix `is_synth` to distinguish panel-gate nodes (`tier4_synth` etc.) from true synth; write `panel-verdict.json` and run the verdict gate for panel gates.
-4. Derive + export `MO_TARGET_CWD` from the kickoff's git toplevel before implementer/publisher dispatch.
-5. Port the pre-dispatch gates: `.stop-requested`, intervention gate, capability assert, stale-heartbeat watchdog.
-6. (degrade) Read `artifact_contract.source_artifact` for the synth output path.
-
-## Harness blind spot (now documented)
-
-`scripts/runtime-parity-harness.sh` deliberately skips live dispatch and `plan --dry-run` routes through `_dry_dispatch_node`, not `dispatch_node`. So it is structurally blind to the entire live-node side-effect class (edit-surface cwd, apply-impl target, publisher commit, verdict gating). The `live_dispatch_harness.py` gate covers the *researcher* wiring only; extend it to implementer (target-cwd) + publisher (commit) + a panel-gate verdict before trusting the live cutover.

-# Remaining migration — first requirements audit gaps
-
-Status: in progress
-
-Last worked on: 2026-07-19 20:55 Europe/Berlin
-
-Source task: `docs/migration/remaining-migration-handoff.md`
-
-## Verify fork closure
-
-Current status: completed and source-applied from the green isolated proposal produced by `run-1784482847-61479`.
-
-### Subtasks
-
-1. Publisher preserves composite run artifacts
-   - Current status: completed locally. Run 3 preserved the mirrored diff, ledger, detailed verdict, reflection, and both requirements audits; the runtime now harvests those allowlisted artifacts before review and keeps generic orchestration status in `run-verdict.json`.
-   - Remaining parts: confirm the repaired ordering in the next explicitly approved paid self-migrate run.
-
-2. Deterministic fork-closure gate
-   - Current status: completed. Run 3 and the source post-apply rerun both passed literal-plus-dynamic closure with process status matching JSON `pass:true`.
-   - Remaining parts: none.
-
-3. Complete verify integration surface
-   - Current status: completed. Run 3 covered the top-level shell caller, legacy executor, Python executor, direct and lifecycle Python CLI dispatch, tests, and parity harness; `bin/mini-ork-verify` is retired.
-   - Remaining parts: none.
-
-4. Preserve the explicit isolated target through reviewer assembly
-   - Current status: implemented, regression-tested, and confirmed by run 2; `review-diff.patch` was a non-empty 31,513-byte worktree delta.
-   - Remaining parts: none for target selection; retain the regression test.
-
-5. Fail closed across JSON and process verifier contracts
-   - Current status: completed. Run 3's ledger gate initially rejected incomplete rows and later passed only after coverage reached 33 rows; all five final process exits matched their JSON result.
-   - Remaining parts: none.
-
-6. Qualified ledger symbol matching
-   - Current status: completed. Run 3 cross-checked the final 45,905-byte diff and passed with 33 rows.
-   - Remaining parts: none.
-
-7. Resolve pre-existing global parity divergences
-   - Current status: deferred outside the verify fork.
-   - Remaining parts: diagnose `help`, `doctor`, `conductor --help`, `execute --help`, and `init` independently; they do not replace or block the fork-specific parity oracle.
-
-8. Apply and commit the verify fork
-   - Current status: completed. The source-applied verify fork, recipe hardening, artifact-handoff repair, tests, handoff, and audit are captured in one focused migration commit.
-   - Remaining parts: none.
-
-9. Make mirrored verifier evidence available before review
-   - Current status: completed. The reflect run live-confirmed same-run map,
-     ledger, detailed verdict, diff, and recipe-report visibility; the follow-up
-     repair also surfaces the standalone pre-retirement report explicitly.
-   - Remaining parts: none.
-
-## Later forks
-
-Current status: `reflect`, `classify`, and `plan` are closed and source-applied from the
-passing isolated proposals in `run-1784503045-70610` and
-`run-1784528328-42404`, plus the audited completion of partial plan run
-`run-1784532524-76798`. `cli` and `execute` are not started, and the ordering
-is unchanged.
-
-Remaining parts: prepare the isolated `cli` target and canonical kickoff from
-the pushed plan-closure commit. After explicit approval, run the same
-five-verifier pipeline with only Kimi, Codex, and GLM. Load Kimi/GLM credentials
-process-locally from `/Users/admin/ps/scripts`, apply only passing diffs, update
-migration documentation, and repeat the requirements audit after each closure.
-
-## Second requirements audit
-
-Completed: 2026-07-19
-
-- Re-read the handoff, feature manifest, recipe README, artifact contract, and corrected verify kickoff.
-- Confirmed run 2's real reviewer diff, both requirements-review artifacts, focused functional evidence, fail-closed partial verdict, and unapplied rollback outcome.
-- Confirmed the publisher regression suite preserves the diff, ledger, and verdict as distinct artifacts.
-- Confirmed explicit worktree targeting wins over an external temporary kickoff path.
-- Confirmed pre-retirement parity runs before the migrator and produces durable passing evidence for the verify fork.
-- Confirmed all five recipe verifier scripts now make process status agree with JSON `.pass` and that qualified ledger symbols satisfy the diff cross-check.
-- Confirmed the complete executor unit module passes (47 tests), Pyright reports zero errors, `mini-ork validate` passes, the restored 52-row ledger passes `ledger-shape.sh`, all verifier scripts pass `bash -n`, and `git diff --check` is clean.
-
-## Third requirements audit
-
-Completed: 2026-07-19
-
-- Confirmed the Run 3 isolated detailed verdict has `pass: true` and all five migration gates passed.
-- Confirmed the 33-row ledger cross-checks the final diff and no literal or dynamic verify caller remains.
-- Confirmed the promoted source files are byte-identical to the verified worktree and `bin/mini-ork-verify` is absent.
-- Confirmed post-apply results: 9 verify tests, 47 executor tests, 6 CLI tests, 8 integration assertions, 18 E2E assertions, focused runtime parity, Pyright with zero errors, and clean diff hygiene.
-- Separated the green implementation verdict from the outer run-level failure caused by reviewer/report ordering.
-
-## Fourth requirements audit
-
-Completed: 2026-07-19
-
-- Re-read the handoff and todo after implementing the artifact-handoff repair.
-- Confirmed the target-run mirror is harvested before reviewer dispatch and only the self-migrate artifact/evidence allowlist is copied.
-- Confirmed reviewer inputs include `verifier_*.json`, `integration-map.json`, `static-feature-ledger.json`, detailed `verdict.json`, and `self-migrate.diff`.
-- Confirmed generic bookkeeping uses `run-verdict.json` and preserves a recipe-owned detailed `verdict.json`.
-- Confirmed all 50 executor tests pass, including same-run mirror visibility, detailed-verdict preservation, and recipe-specific reviewer evidence.
-- Confirmed 15 verify/CLI unit tests, 8 integration assertions, 18 E2E assertions, Pyright, validate, shell syntax, diff hygiene, and garden (0 errors, 0 warnings) pass.
-- Ran the repository-wide suite directly because `make test` has no target: 1,805 passed, 5 skipped, and 3 source-checkout-state failures (one user-owned capability-policy mismatch and two reflect cases). The reflect failures reproduced in the dirty source checkout, were not changed, and do not reproduce in the clean isolated migration target, where all 8 tests pass.
-
-The verify, reflect, classify, and plan forks and their artifact-handoff
-prerequisites are done locally. The later two forks remain pending in the
-required order and need explicit cost approval one run at a time; the next paid
-run is `cli`.

-# Reflect migration — requirements audit gaps
-
-Status: completed
-
-Last worked on: 2026-07-20 02:35 Europe/Berlin
-
-Source task: `docs/migration/remaining-migration-handoff.md`
-
-Run under audit: `run-1784503045-70610`
-
-## Requirements confirmed
-
-- The isolated proposal deletes `bin/mini-ork-reflect` and repoints every
-  runtime caller to `mini_ork.cli.reflect`.
-- The live target diff is byte-identical to the preserved
-  `self-migrate.diff` (`sha256: 173793e43fb3d24355b4d0683101c3d9578fa536157ceb7d51ed4efaecfb8f03`).
-- Pre-retirement parity, post-retirement parity, feature acceptance, the
-  27-row ledger, and fork closure all pass.
-- Reviewer verdict and detailed `verdict.json` pass; focused unit, integration,
-  E2E, Pyright, executor/CLI, validation, syntax, and diff-hygiene checks pass.
-- The four added documentation updates replace references to the deleted Bash
-  runtime with the canonical Python pipeline and are accepted as required
-  migration-documentation scope.
-
-## Subtasks
-
-1. Surface the standalone pre-retirement report to the reviewer
-   - Current status: completed. Reviewer input assembly now includes the
-     standalone `pre-retirement-parity.json` whenever it exists, and focused
-     regression coverage confirms the report reaches the reviewer prompt.
-   - Remaining parts: none.
-
-2. Explain the outer run-level failure count
-   - Current status: completed without a paid replay. The generic hollow-run
-     guard required final migration artifacts before every verifier, including
-     `pre_retirement_parity`, which is intentionally ordered before the
-     migrator. That baseline node produced the only false failure count; the
-     serial pipeline later passed all five reports and still ran rollback.
-     Executor dispatch now derives the exception from workflow order: verifier
-     nodes before the first implementer may capture their baseline oracle,
-     while all later verifiers remain fail-closed on missing final artifacts.
-   - Remaining parts: none. Regression coverage proves both sides of the phase
-     boundary.
-
-3. Promote and verify the reflect proposal
-   - Current status: completed locally. The preserved proposal was applied to
-     the source checkout, the two executor evidence/accounting seams were
-     repaired, and the focused reflect and executor gates are green.
-   - Remaining parts: none.
-
-4. Track unrelated global gate drift
-   - Current status: diagnosed, not part of the reflect fork. The all-feature
-     learning-loop closure gate fails two static assertions already absent at
-     baseline `ecd7f783` and one live-data assertion against the newly
-     initialized empty runtime DB.
-   - Remaining parts: none in this task; do not change unrelated learning-loop
-     tests or implementation without explicit user confirmation.
-
-## First requirements audit
-
-Completed: 2026-07-20
-
-- Re-read the migration handoff, reflect kickoff, feature manifest, recipe
-  workflow, artifact contract, and verifier reports.
-- Cross-checked the reviewer against the integration map and inspected every
-  non-deletion source/documentation change.
-- Replayed focused tests and deterministic migration gates in the isolated
-  target.
-- Recorded the missing reviewer report as a blocking subtask before source
-  completion.
-
-## Second requirements audit
-
-Completed: 2026-07-20
-
-- Re-read the migration handoff, reflect kickoff, feature manifest, recipe
-  workflow, artifact contract, and all five verifier reports after applying the
-  proposal.
-- Confirmed every runtime caller now uses
-  `mini_ork.cli.reflect`, the Bash entrypoint is deleted, and the
-  deterministic closure verifier passes against the source checkout.
-- Confirmed reviewer assembly now includes the standalone pre-retirement
-  report plus recipe-specific verifier reports, map, ledger, detailed verdict,
-  and diff.
-- Reproduced the false failure condition from code: the pre-implementation
-  verifier was subject to a post-implementation artifact guard. Added a
-  phase-aware workflow-order check and regression tests preserving the guard
-  for every later verifier.
-- Re-ran the 11 reflect/GEPA tests, 11 integration assertions, 8 parity cases,
-  reflect feature acceptance, 27-row ledger shape, fork closure, Bash syntax,
-  57 executor/CLI tests, Pyright, and diff hygiene; all pass.
-- Confirmed the unrelated all-feature learning-loop drift remains outside this
-  fork and was not modified.
-
-All reflect technical and product requirements are satisfied locally. The next
-fork in the documented sequence is `classify`; its paid self-migrate launch
-requires separate explicit approval.

-# Classify migration — requirements audit gaps
-
-Status: completed
-
-Last worked on: 2026-07-20 09:00 Europe/Berlin
-
-Source task: `docs/migration/remaining-migration-handoff.md`
-
-Run under audit: `run-1784528328-42404`
-
-## Subtasks
-
-1. Make the BDD-first verifier use its isolated project consistently
-   - Current status: completed. The test now exports the same explicit engine,
-     project-home, and target-repository contract as the code-fix E2E harness;
-     the exact command passes 18 assertions.
-   - Last time worked on: 2026-07-20 08:47 Europe/Berlin.
-   - Remaining parts: none.
-
-## First requirements audit
-
-- Re-read the migration handoff, self-migrate manifest, run integration map,
-  feature ledger, recipe prompt, artifact contract, and verifier contract.
-- Confirmed the native classify and trace-store ports contain no subprocess,
-  Popen, system, or print calls.
-- Repointed the mapped runtime, CLI, validation, integration, E2E, security,
-  script, sandbox, UI, demo, and comment seams to the Python runtime.
-- Converted the live Bash parity unit suite into standalone golden contracts
-  after confirming the durable pre-retirement report passed 5 tests.
-- Found one verifier-harness gap after the classify assertions passed: the
-  BDD-first test initializes from the engine directory instead of its isolated
-  project directory.
-
-## Second requirements audit
-
-- Re-read the migration handoff, feature manifest, migrator prompt, artifact
-  contract, integration map, 29-row ledger, and all five verifier reports.
-- Programmatically matched every integration-map inbound path to a changed file.
-- Reconfirmed both `mini_ork_classify.py` and the imported native
-  `trace_store.py` contain no subprocess/Popen/system nodes and no `print()`
-  calls; classify stdout remains limited to its documented contract.
-- Confirmed `bin/mini-ork-classify` is absent, the top-level Bash and Python CLI
-  direct-subcommand paths invoke the module, and closure scans find no literal
-  retired path or dynamic `_bin(..., "classify")` caller.
-- Replayed the standalone 9-test classifier contract, 6-test Python CLI suite,
-  9-assertion classify integration test, seven security suites, three E2Es,
-  post-MVP integration, focused Pyright, Bash/Python syntax checks, and all five
-  migration gates. All pass after the BDD harness correction.
-
-All classify technical and product requirements are satisfied in the isolated
-proposal. The reviewed proposal was then applied to the source checkout without
-touching the user-owned `.mini-ork/config/agents.yaml`.
-
-## Source promotion audit
-
-- Confirmed `git apply --check` succeeded before promotion and the generated
-  proposal has SHA-256
-  `cba03d84c3165732ec98a5b7fd055893d2542823a0c7d4adf6a0fd4cb484775f`.
-- Replayed 15 classify/CLI unit tests, 9 classify integration assertions, 16
-  post-MVP integration assertions, 43 security assertions, and 53 E2E
-  assertions; all pass.
-- Re-ran classify feature acceptance, focused Pyright, post-retirement parity,
-  feature acceptance, ledger shape, fork closure, and diff hygiene; all pass.
-- Diagnosed the outer `__gates__` failure as an orchestration-context defect:
-  `mini_ork_verify.py` omits keys required by globally registered oracle gates,
-  and its aggregate treats `defer` as failure. The self-migrate reports and
-  implementation are green, so no paid retry was performed.
-
-## Second completion audit
-
-- Re-read the canonical handoff, classify kickoff, run integration map,
-  detailed verdict, reviewer report, and all five verifier reports after source
-  promotion.
-- Confirmed every migration-owned code and test path in the source checkout is
-  byte-identical to the independently verified isolated target, and confirmed
-  `bin/mini-ork-classify` remains absent.
-- Re-ran the complete focused source proof: 15 classify/CLI unit tests, 25
-  integration assertions, 43 security assertions, 53 E2E assertions, classify
-  feature acceptance, focused Pyright, durable pre-retirement evidence, all
-  four post-retirement gates, and diff hygiene. All pass.
-- Reconfirmed that the global oracle-gate context defect is outside the
-  classify fork: no classify verifier or reviewer failed, and no paid retry is
-  justified.
-
-All classify technical and product requirements are satisfied in the source
-checkout. The next migration fork is `plan`; its paid run still requires
-separate explicit approval.

-# Execute migration requirements audit — loop 1
-
-Status: completed
-
-Last worked on: 2026-07-20 13:06:23 Europe/Berlin
-
-## Task: compare the implementation with the execute kickoff and migration docs
-
-Current status: the first full pass found four functional gaps and one
-documentation gap. All were converted into subtasks and completed before the
-second audit.
-
-### Subtask: restore default-on process-reward scoring
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Successful trace writes invoke the native PRM scorer by
-default, persist `process_reward`, and honor `MO_PRM_SCORE=0`.
-
-### Subtask: wire the minimal scaffold into live execute
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. `MO_SCAFFOLD_TIER=minimal` uses the native minimal agent,
-writes the implementer artifact, and never invokes the provider harness.
-
-### Subtask: preserve resolved model routing and fallback
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Execute passes its resolved role-aware chain as an
-explicit model override, avoiding a second agent-role lookup. The dispatcher
-records the model that actually served the request when a fallback wins.
-
-### Subtask: restore plan task-class precedence
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Live execute resolves `task_class` from `plan.json`,
-then `MINI_ORK_TASK_CLASS`, then `generic`, matching the retired executor.
-
-### Subtask: remove stale current-runtime references
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Current operator, architecture, feature, recipe, and
-migration surfaces now name `mini-ork execute` or the Python executor. Historical
-audits, research snapshots, and incident reports retain their original paths.
-
-### Verification
-

-# Execute migration requirements audit — loop 2
-
-Status: completed
-
-Last worked on: 2026-07-20 13:45:31 Europe/Berlin
-
-## Task: independently re-check the completed execute migration
-
-Current status: every technical and product requirement in
-`kickoffs/migration/execute.md`, the migration handoff, and the completion plan
-is satisfied. No unsatisfied requirement remains.
-
-### Subtask: re-check sole ownership and fork closure
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. The public CLI routes execute in-process,
-`bin/mini-ork-execute` is absent, and the deterministic closure scan finds no
-live literal, dynamic `_bin`, source, or executable caller edge.
-
-### Subtask: re-check behavior and learning contracts
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Dispatch routing, fallback, context, capability,
-intervention, reviewer, verifier, publisher, rollback, checkpoint, telemetry,
-PRM/GRPO, serial/parallel/partitioned/speculative, and failure contracts all
-have passing focused or integration evidence.
-
-### Subtask: re-check durable migration evidence
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Pre-retirement parity, post-retirement parity, feature
-acceptance, the 76-row static ledger, and fork closure all pass against the
-final generated diff.
-
-### Subtask: re-check OSS and commit scope
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Repository changes are limited to the execute migration,
-its callers, tests, active documentation, and audit records. Runtime homes,
-logs, databases, credential values, local adapters, and the user's existing
-`.mini-ork/config/agents.yaml` are excluded.

-# CLI migration completion audit
-
-Status: completed
-
-Last worked on: 2026-07-20
-
-## Task: close the top-level CLI fork
-
-Current status: the isolated review proposal closes the CLI fork; no source
-change has been committed or applied to the real checkout.
-
-### Subtask: preserve the public launcher while retiring Bash
-
-Current status: completed.
-
-Remaining parts: none.
-
-Implementation details:
-
-- `bin/mini-ork` is an executable Python launcher that resolves symlinks and
-  imports `mini_ork.cli.main.main` without runtime selection.
-- CLI-specialized closure proves the public path exists and is Python-only.
-- Golden launcher tests cover exact version/help/unknown behavior and symlink
-  invocation.
-
-### Subtask: repair already-closed direct command routes
-
-Current status: completed.
-
-Remaining parts: none.
-
-Implementation details:
-
-- Direct `classify`, `plan`, `verify`, and `reflect` routes invoke their native
-  Python modules.
-- `apply` remains available through its live sibling entrypoint.
-- `execute` intentionally remains the one live Bash command fork.
-
-### Subtask: close CLI runtime seams
-
-Current status: completed.
-
-Remaining parts: none.
-
-Implementation details:
-
-- Public-path scheduler, spawn, sandbox, web, CI, installer, and research
-  callers remain valid without churn because the argv contract is unchanged.
-- Deadline, config snapshot, repository integrity, rubric scoring, and reward
-  grading now call native Python ports; best-effort and stdout contracts are
-  preserved explicitly.
-
-### Subtask: satisfy migration gates
-
-Current status: completed.
-
-Remaining parts: none.
-
-Evidence:
-
-- Durable pre-retirement evidence remains green in the run directory.
-- A third audit detected that the original helper could delegate back to
-  Python. Corrected true-Bash evidence now proves 40 legacy dispatcher
-  assertions plus exact version/help/doctor/error parity.
-- 8 standalone CLI tests and 46 dispatcher assertions pass.
-- Focused Pyright reports zero errors.
-- Post-retirement parity, CLI feature acceptance, the 48-row ledger, and
-  CLI-specialized fork closure pass.
-- Three source-requirements audits are recorded under `docs/todos/`; the third
-  corrected the runtime-selection flaw in the original Bash oracle before
-  final promotion.

-# Execute migration completion audit
-
-Status: completed
-
-Last worked on: 2026-07-20
-
-## Task: close the final execute fork
-
-Current status: all execute technical and product requirements are satisfied.
-The Bash executor is retired, the public CLI owns the native route, and the
-final diff is ready for focused clean-main promotion.
-
-### Subtask: capture a real Bash oracle
-
-Current status: completed before retirement.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. The explicit `MINI_ORK_RUNTIME=bash` receipt preserves
-51 unit tests, 10 integration assertions, and focused type-check evidence after
-the Bash entrypoint is deleted.
-
-### Subtask: close outbound Bash-library seams
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Dispatch, capability checks, learned context, operator
-steering, intervention gating, liveness, gate bootstrap, and gate registry are
-native. Provider, git, and executable verifier contracts remain explicit
-external boundaries.
-
-### Subtask: preserve runtime and product contracts
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. The completion audit restored four gaps found after the
-model-authored proposal:
-
-- process-reward scoring is default-on and keeps its opt-out;
-- the minimal scaffold bypasses the provider harness;
-- the resolved role-aware model chain reaches dispatch without a second lane
-  lookup, and selected fallback telemetry records the actual model;
-- direct execute reads `task_class` from `plan.json` before falling back to the
-  environment and `generic`.
-
-Publisher allowlisting, reviewer input assembly, checkpointing, trace scoping,
-bounded concurrency, rollback, and failure contracts have focused coverage.
-
-### Subtask: repoint every inbound runtime edge
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Direct execute and the run lifecycle route in-process;
-scripts, gates, tests, web/operator text, and active recipe comments point to
-the native runtime; obsolete Bash-oracle tests are replaced by standalone
-Python/golden contracts; and `bin/mini-ork-execute` is absent.
-
-### Subtask: satisfy migration and product gates
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Evidence includes 57 execute tests, 11 dispatcher tests,
-88 adjacent native-port/CLI tests, 10 execute integration assertions, the broad
-E2E/integration suite, the duration and isolated observability probes, focused
-Pyright, and all five self-migrate gates. The static ledger covers all 76
-changed functions discovered in the final diff.
-
-### Subtask: enforce provider and OSS scope
-
-Current status: completed.
-
-Last time worked on: 2026-07-20.
-
-Remaining parts: none. Exactly one paid run used Kimi, Codex, and GLM; MiniMax
-and DeepSeek were excluded. The paid review returned `needs_revision`, so the
-remaining deterministic repairs were made locally without a paid retry. No
-credential value, local provider adapter, runtime home, state database, or
-user-owned `.mini-ork/config/agents.yaml` is part of the migration diff.

-# Gradient native-dispatch requirements audit
-
-Status: completed
-
-## Task: remove the silent Bash-era no-op from native reflection
-
-Status: completed
-Last worked on: 2026-07-20
-Remaining parts: none for the production caller edge; Bash library/test
-retirement is the next ownership unit.
-
-### Requirements from the migration task and docs
-
-1. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. Default gradient extraction calls the native,
-   telemetry-aware dispatcher without sourcing `lib/llm-dispatch.sh`.
-2. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. Prompt substitution, model selection, timeout/turn
-   limits, fenced/truncated recovery, and evidence/confidence defaults persist.
-3. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. Reflection defaults use native extract, store, and
-   schema operations; deterministic injection remains available for tests.
-
-### Completion audit loop 1
-
-- Technical requirements: native dispatch, telemetry-aware routing, tolerant
-  parsing, trace linkage, persistence, and reflection composition are covered.
-- Product requirements: a normal public reflection run can now create learning
-  gradients instead of swallowing an unimplemented default and reporting green.
-- Unsatisfied requirements found: none for the production caller unit.
-
-### Completion audit loop 2
-
-- Re-read the reflection/gradient modules, configuration docs, migration handoff,
-  tracker, and caller tests after implementation.
-- Twenty-nine combined gradient/reflection/public-reflect tests passed. Pyright
-  reported zero errors and Python compilation succeeded.
-- A real GLM 5.2 request extracted three valid gradients from a persisted,
-  evidence-rich verifier failure. No MiniMax or DeepSeek request ran.
-- `mini-ork validate` passed; garden returned zero errors and the pre-existing
-  missing `docs/operator/env-vars.md` warning.
-- Closure, diff, secret, and provider-policy scans found no unsatisfied caller
-  requirement. Bash library and test retirement remains explicitly separate.

-
-### Subtasks
-
-1. Status: completed
-   Last worked on: 2026-07-20

-   without creating `lib/llm-dispatch.sh`.
-3. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. The migration plan's stale MiniMax tooling guidance
-   was replaced by the approved temporary Kimi/Codex/GLM policy.
-4. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. Focused tests, Pyright, a real GLM 5.2 public-path
-   probe, closure scanning, and OSS secret/scope scanning passed.
-5. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. The three BDD-first inbound callers now pass
-   `MINI_ORK_PROMPT_FILE`, matching the public utility contract.

-# Plan fork migration blockers — resolved
-
-Status: completed
-Last worked on: 2026-07-20
-
-The plan fork cannot retire yet. The pre-retirement suite is green for its
-covered cases, but a second requirements audit found Bash-owned behavior that
-is absent from both `integration-map.json` and `static-feature-ledger.json`.
-
-## Task: port every omitted planner contract before retirement
-
-Status: completed
-Last worked on: 2026-07-20
-Remaining parts: none.
-
-1. Profile normalization and question handling — completed
-   - Native zero-question normalization, `/dev/tty` input, auto-answering,
-     profile mutation, confidence floor, and blocking contracts are covered by
-     standalone planner tests.
-
-2. Planner context assembly — completed
-   - Learned failure modes, prior-run memory, the planner role pack, generic
-     ContextNest fallback, recent sessions, and active state use native Python
-     modules with best-effort failure isolation and ordered prompt coverage.
-
-3. Context-pack persistence — completed
-   - Non-dry runs persist `context-pack.json` through native
-     `context_assemble`; focused tests assert its path and payload.
-
-4. Trace lifecycle writes — completed
-   - Native best-effort traces cover running, blocked, fallback, dispatch and
-     validation failures, and success. Migration 0054 makes `blocked` a valid
-     canonical status and preserves existing trace rows.
-
-5. Strengthen the retirement oracle — completed
-   - The durable pre-retirement report remains preserved, the completion ledger
-     contains 58 rows, and post-retirement parity, feature acceptance, Pyright,
-     ledger shape, and fork closure are green. `bin/mini-ork-plan` is retired.
-
-## Work completed in this attempt
-
-- Replaced the Python planner's Bash `llm-dispatch.sh` subprocess with the
-  native `mini_ork.dispatch.llm_dispatch.llm_dispatch` API.
-- Preserved combined stdout/stderr capture and added a standalone native seam
-  contract.
-- Repointed known executable callers and expanded the plan feature verifier.
-- Deleted the Bash entrypoint after the completion audit closed every blocker.

-
-Status: completed
-Last worked on: 2026-07-20

-
-### Requirements from the migration task and docs
-
-1. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. The planner is the only production inbound caller
-   and already imports `mini_ork.steering.profile_answerer` directly.
-2. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. Tests use standalone golden contracts rather than a
-   live Bash oracle, and web smoke verifies that the Bash owner is absent.
-3. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. The native default follows the latest supported
-   commit history: Kimi primary plus one Kimi retry after failure or whitespace.
-4. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. `lib/profile_answerer.sh` is removed and closure scans
-   retain only deliberate absence assertions and migration history.
-
-### Completion audit loop 1
-
-- Technical requirements: native ownership, deterministic behavior coverage,
-  provider retry parity, and inbound-reference closure are satisfied.
-- Product requirements: autonomous profile answers remain concise, complete,
-  and persisted in the same JSON shape; the banned DeepSeek regression is
-  removed from this lane.
-- Unsatisfied requirements found: none.
-
-### Completion audit loop 2
-
-- Re-read the migration handoff, completion plan, and predecessor audit after
-  implementation; all now describe sole native ownership and Kimi retry order.

-### Requirements from the migration task and docs
-
-1. Status: completed
-   Last worked on: 2026-07-20

-4. Status: completed
-   Last worked on: 2026-07-20
-   Remaining parts: none. The legacy Bash body, duplicate serial Python port,
-   and Bash-oracle suite are retired without reducing behavioral coverage.
-
-### Completion audit loop 1
-
-- Technical requirements: CLI flags and exit codes, priority inheritance,
-  deterministic ordering, cost controls, kickoff resolution, verdict lookup,
-  status mutation, dependency cascade, and concurrency are covered.
-- Product requirements: the stable operator command and conductor caller remain
-  compatible while the intended cross-epic parallelism is now actually used.
-- The historical `--epic`/`--roadmap` scope-filter proposal remains an
-  independent product backlog item; migration preserves the supported queue
-  behavior and does not silently add a new selection policy.
-- Unsatisfied migration requirements found: none.
-
-### Completion audit loop 2
-
-- Re-read the migration tracker, recursive ownership plan, multi-epic learning
-  guide, public callers, and test surfaces after implementation.
-- Fourteen standalone scheduler contracts passed, including CLI-main concurrent
-  admission of three 0.6-second workers in under 1.5 seconds and Python
-  classification of the generated launcher verification command.
-- The combined scheduler, conductor, and epics caller suite passed 26 tests.
-- The autonomous epic pipeline passed all 13 assertions. Pyright reported zero
-  errors, compilation and `mini-ork validate` passed, and garden returned zero
-  errors plus the pre-existing missing `docs/operator/env-vars.md` warning.
-- The broad runtime-parity harness has unrelated conductor/init failures that
-  reproduce under the legacy Bash runtime; focused scheduler help parity passes.
-- Closure, diff, and scope scans found no unsatisfied migration requirement.

-# Daytona codebase-ingest live credential follow-up
-
-**Status:** blocked on service credential configuration  
-**Last worked on:** 2026-07-26  
-**Scope:** Researcher-managed Daytona execution of MiniOrk's codebase-ingest recipe
-
-## What was verified
-
-- A clean Daytona sandbox cloned the current MiniOrk repository over HTTPS,
-  installed the user launcher, initialized a fresh Git project, validated it,
-  and completed the code-fix dry-run.
-- The Researcher service created a Daytona sandbox, uploaded the
-  codebase-ingest overlay recipe, cloned the target repository, and started
-  MiniOrk's planner.
-- The provider-backed planner then failed with HTTP 401 before any parallel
-  lenses ran. The report artifact was therefore not produced.
-
-## Remaining work
-
-1. Repair the Researcher service's provider configuration so the planner has
-   both a valid credential and explicit model metadata.
-2. Keep credential preflight enabled; it must accept the codebase-ingest
-   recipe without a diagnostic bypass.
-3. Re-run the recipe against https://github.com/SourceShift/mini-ork.git at
-   main with the architecture, runtime, learning, and recipe facets.
-4. Verify that the output artifact contains findings from every configured
-   lens, identifies the checked repository revision, and records a verified
-   completion status.
-5. Retain the run ID and artifact path as the end-to-end acceptance evidence.
-
-## Acceptance command shape

-~~~text
-Researcher runMiniOrkInSandbox(
-  recipe: codebase-ingest,

-Success means a provider-backed completed run with the structured
-codebase-ingest report—not merely sandbox creation, cloning, or a dry run.

+# Design research: agent sandboxing + orchestrators like mini-ork (2026-06-30)
+
+**Why this exists.** mini-ork is a bash "task OS for agents" (classify→plan→
+execute→verify→reflect→improve loop, recipe runner, heterogeneous LLM lanes,
+GRPO learning, git-worktree isolation). Its #1 architectural gap (**A1** in the
+fix tracker): **agents run directly on the host OS filesystem** — no per-agent
+sandbox. That (a) blocks cloud/remote execution and (b) just caused cross-repo
+corruption (a stray codex process reset another repo's git HEAD). This doc surveys
+how the ecosystem solves these problems and what mini-ork should borrow.
+
+Sources: jina/web search 2026-06-30 — `restyler/awesome-sandbox`, spheron isolation-stack
+breakdown, `SWE-agent/swe-rex`, augmentcode "9 open-source agent orchestrators",

+---
+
+## A. Agent filesystem isolation & cloud execution  *(the priority)*
+
+### A.1 The isolation taxonomy (from `awesome-sandbox` + spheron)
+
+| Class | Mechanism | Examples | Boot | Isolation strength | Self-host |
+|---|---|---|---|---|---|
+| **MicroVM** | own Linux kernel via KVM | **Firecracker**, **libkrun** | ~125ms | **strongest** (hardware) | yes |
+| **App kernel** | intercept syscalls in userspace | **gVisor**, nsjail | ~tens ms | strong (syscall boundary) | yes |
+| **Container** | namespaces + cgroups | Docker/OCI, **Kata** (container API, VM under) | ~10-50ms | weakest (shared kernel) | yes |
+| **Language runtime** | WASM / V8 isolate | WebContainers, Cloudflare Workers | ~1-10ms | medium, but no full Linux | n/a |
+
+Consensus ranking (multiple sources): **microVM (Firecracker/Kata) > gVisor > plain container.**
+"The minimum acceptable isolation for a production agent execution sandbox is
+typically a Firecracker/Kata microVM, with gVisor used in some cases." Firecracker
+adds a "jailer" companion (cgroups+namespaces) for defense-in-depth; it's what AWS
+Lambda/Fargate run on.
+
+### A.2 Managed sandbox platforms (don't build the VM layer yourself)
+
+| Platform | Under the hood | OSS / self-host | Note |
+|---|---|---|---|
+| **E2B** (`e2b.dev`) | Firecracker microVM per sandbox | OSS, self-hostable | "made to run untrusted workflows"; own kernel + memory, no shared state |
+| **Daytona** | gVisor default + elastic infra | OSS | "secure & elastic infra for AI code"; Docker isolation by default = weaker |
+| **microsandbox** | **libkrun** microVMs, self-hosted | OSS | self-hosted microVMs for untrusted code |
+| **Modal** | gVisor | hosted | no microVM option |
+| **Beam / Northflank / Fly.io** | containers / microVMs | hosted (Fly = microVMs) | GPU-ready picks |
+
+### A.3 What mini-ork should do (A1 fix direction)
+1. **Introduce a `Sandbox` boundary** each agent gets: an isolated rootfs + a single
+   mounted, scoped workspace dir. An agent must not be able to `cd` to or write any
+   path outside its workspace — this *structurally* prevents the cross-repo HEAD
+   clobber we hit, in addition to enabling cloud.
+2. **Tiered backends** behind one interface: `local-worktree` (today, dev only) →
+   `docker`/`gVisor` (cheap CI) → `firecracker`/`microsandbox` or `E2B`/`Daytona`
+   (untrusted/cloud). Pick per recipe via an env knob (`MO_SANDBOX_BACKEND`).
+3. **Don't build the VM layer** — wrap E2B/Daytona/microsandbox. They already solve
+   boot-time + jailer + snapshotting.
+
+---
+
+## B. Runtime-abstraction layer — the SWE-ReX pattern  *(highest-leverage borrow)*
+
+**SWE-ReX** (`SWE-agent/swe-rex`) is the cleanest model for mini-ork's executor:
+
+> "a runtime interface for interacting with sandboxed shell environments, allowing
+> you to effortlessly let your AI agent run **any command on any environment** —
+> local, Docker, AWS, Modal, Daytona — massively parallel (30+ agents)."
+
+The idea: **decouple the agent logic from where commands physically run.** The agent
+calls `run(command)` against a *deployment* (local / container / microVM / cloud);
+the deployment handles transport, sessions, and isolation. Same agent code runs on a
+laptop or 30 cloud microVMs.

+```
+
+**Borrow:** define a thin `lib/runtime/*.sh` (or the Python `mini_ork.dispatch`
+already started) interface — `runtime_exec`, `runtime_put`, `runtime_get`,
+`runtime_session` — with a `local` impl (current behavior) and a `container` impl
+first. Recipes/executor call the interface, never `cd`+`bash` directly. This is the
+single change that unlocks cloud execution *and* fixes A1.
+
+---
+
+## B.1 mini-SWE-agent — the minimalist sibling, and the cheapest path to A1
+
+`SWE-agent/mini-swe-agent` (Princeton/Stanford SWE-bench team; used by Meta, NVIDIA,
+IBM, Anyscale; **>74% SWE-bench verified in ~100 lines, bash-only**) is the most
+directly relevant repo to mini-ork — and it has already solved A1 by *design*, not by
+adding infrastructure. Three properties make sandboxing/cloud trivial:
+
+1. **Every action is an independent, stateless `subprocess.run`** — NOT a persistent
+   shell session. Their own words: *"this is a big deal for stability… it makes it
+   trivial to execute actions in sandboxes — literally just switch out `subprocess.run`
+   with `docker exec` — and to scale up effortlessly."*
+   → **This is the crux of A1.** mini-ork's executor keeps stateful shell context and
+   `cd`s the host, so it can't be swapped to a sandbox backend. If actions were
+   stateless + routed through a single exec function, swapping local→`docker exec`→
+   microVM would be a one-line backend change (== R1, the runtime interface).
+2. **Bash-only, no custom tools, no tool-calling interface** — works with *any* model;
+   "want a PR? just tell the LM to figure it out." mini-ork is already bash-centric, so
+   this validates the direction and argues against over-building tools.
+3. **Completely linear history** — messages == trajectory (great for debugging + FT).
+   Relevant to mini-ork's I-14 observability mess (multiple status sources): a linear
+   append model is easier to render faithfully.
+
+**Deployable backends it ships out of the box:** local, **docker/podman**,
+**singularity/apptainer**, **bubblewrap**, contree. Note **bubblewrap** — an
+unprivileged, lightweight FS/namespace sandbox (no VM, no daemon). That's the ideal
+*cheap middle tier* for mini-ork between "local worktree" and "microVM/E2B": real
+path/namespace isolation that would have *prevented the cross-repo HEAD clobber*, with
+near-zero overhead. Models are pluggable via **litellm/openrouter/portkey** (vs
+mini-ork's hand-rolled `lib/providers/cl_*.sh`).
+
+**Borrow, concretely:**
+- Refactor the executor so a recipe action is a **stateless exec call** through one
+  function (`runtime_exec`), the way mini-SWE-agent uses `subprocess.run`. This is the
+  prerequisite that makes R1/R2 cheap rather than a rewrite.
+- Add a **bubblewrap backend** as the first real sandbox tier (cheap, no daemon) before
+  reaching for Docker/microVM.
+- Steal its trajectory-browser + linear-history model for I-14.
+
+## C. Orchestration topology — what mini-ork already does well vs. what to borrow
+
+The augmentcode roundup of **9 OSS coding-agent orchestrators** (Composio, Emdash,
+Baton, Conductor family [conductor.build, Code Conductor, MS Conductor], Bernstein,
+Claude Squad, Crystal/Nimbalyst, Vibe Kanban, Agent Kanban) converges on one lesson:
+
+> "**Git worktrees became the consensus isolation primitive** within ~18 months.
+> The interesting differences are what each project built on top."
+> The single-agent assumption "breaks the moment I run three agents against the same
+> repo. They clobber each other's files, fight over the dev server port, and leave me
+> reconstructing what happened from `git reflog`."
+
+**That is precisely mini-ork's corruption story.** Worktrees are necessary but *not
+sufficient* — they don't stop a process from reaching outside its worktree (our bug).
+Hence Section A/B (real FS boundary) matters even with worktrees.
+
+What's worth borrowing from this tier:
+- **Kanban/board state model** (Vibe Kanban, Agent Kanban): explicit per-task lanes
+  with visible status — maps to mini-ork's epics/scheduler but with a UI for
+  conflict/merge decisions (mini-ork's I-14 observability gap).
+- **Explicit merge/conflict-resolution stage** — all of them flag that task
+  alignment + conflict resolution + merge decisions are still manual; a dedicated
+  "janitor/verify→merge" node (one orchestrator uses `Goal → Planner → Task Graph →
+  Orchestrator → Agents(parallel) → Janitor(verify) → Git`) is the pattern mini-ork's
+  auto-merge already approximates — harden it.
+- **Control plane with policy/approval gates + audit trail** (the `ai-orchestration`
+  topic's "open agent control plane") — mini-ork has gates; add the audit-trail/HITL
+  approval surface (v0.6.0 already started a control plane + steering checkpoint).
+
+**OpenHands** (most-starred OSS agent) is worth studying for its **EventStream
+architecture** (controller process drives the agent loop; runtime is a separate
+Docker/remote process) and **remote runtime** — a clean split mini-ork lacks.
+
+---
+
+## D. Self-improvement loops — mini-ork is on-trend; one key finding
+
+mini-ork already uses **GRPO + a PRM + "textual gradients."** The ecosystem:
+- **TextGrad** (`zou-group/textgrad`) — "backpropagation through text feedback from
+  LLMs"; the gradient metaphor mini-ork's `gradient_extractor.sh` echoes.
+- **DSPy + GEPA** (`gepa-ai/gepa`) — GEPA = reflective *prompt* evolution (genetic-
+  Pareto). **Key result (arXiv 2507.19457): GEPA beats GRPO by ~10% avg (up to 20%)
+  using up to 35× fewer rollouts.** For mini-ork's expensive multi-LLM rollouts, a
+  GEPA-style reflective evolution of recipe prompts could be far cheaper than GRPO.
+- **Trace / AgentEvolver / ADAS** — automated design of agentic systems (survey
+  preprints.org 202606.0238) — relevant to mini-ork's recipe-evolution ambitions.
+
+**Borrow:** add a GEPA-style reflective prompt-evolution optimizer alongside GRPO and
+A/B them on the learning loop; GEPA's rollout efficiency directly attacks mini-ork's
+cost pain (I-4).
+
+---
+
+## E. Multi-model panels / judges — mini-ork's lenses, externally validated
+
+mini-ork's heterogeneous "lens panel + arbiter" is a recognized pattern:
+- **`lechmazur/debate`** — adversarial multi-turn debate judged by a **3-model panel**
+  (winner + margin + diagnostic scores) — mirrors mini-ork's cross-family panel.
+- **`karpathy/llm-council`** — models answer, cross-review, then a chairman synthesizes.
+- Surveys: `Awesome-LLM-Ensemble` (arXiv 2502.18036), `Awesome-LLMs-as-Judges` — and a
+  caution: LLM judges have **positional/knowledge/format bias** (randomize order,
+  diversify families). mini-ork already diversifies families (memory: opus/codex/kimi
+  /minimax/glm); add **position randomization + bias checks** to the arbiter.
+- **`North-Shore-AI/crucible_ensemble`** — "massively concurrent SLM ensembles reach
+  99.9% reliability at <10% the cost of one big model" — a cheaper-quorum idea for the
+  I-1 lens-quorum fix.
+
+---
+
+## F. Concrete recommendations for mini-ork (priority-ordered)
+
+| # | Recommendation | Closes | Effort |
+|---|---|---|---|
+| R0 | **Make recipe actions stateless** (mini-SWE-agent's `subprocess.run`-per-action model) routed through ONE exec function — the prerequisite that turns R1/R2 from a rewrite into a backend swap | A1 enabler | med |
+| R1 | **Runtime-abstraction interface** (`runtime_exec/put/get`), `local`+`container` impls; executor/recipes stop `cd`+`bash`-ing the host | A1, enables cloud, M4 corruption | high |
+| R2 | **Per-agent sandbox with a hard workspace boundary** — start with **bubblewrap** (cheap, no daemon, would've stopped our clobber), then Docker/gVisor, then microVM/E2B/Daytona; `MO_SANDBOX_BACKEND` knob | A1, M4 | high (bwrap tier: low) |
+| R3 | **Wrap a managed sandbox** (E2B or Daytona or self-hosted microsandbox/libkrun) rather than building VM mgmt | A1 cloud | med |
+| R4 | **GEPA-style reflective prompt evolution** alongside GRPO (35× fewer rollouts) | I-4 cost, learning | med |
+| R5 | **Kanban/board UI + explicit merge node** for the epics/scheduler (borrow Vibe Kanban / OpenHands EventStream) | I-14, I-15 | med |
+| R6 | **Arbiter bias controls** (position randomization, family diversity already done) + cheap-SLM quorum | I-1, judge quality | low |
+| R7 | **Adopt OpenHands' controller/runtime split** as the architectural target for the bash→python migration already underway (`mini_ork.dispatch`) | A1, I-14 | high |
+
+> **Bottom line:** mini-ork is competitive at the orchestration + learning layers, but
+> the field has standardized on a **runtime-abstraction + real-sandbox** stack
+> (SWE-ReX + Firecracker/gVisor/E2B/Daytona) that mini-ork lacks. Building R1+R2 is
+> the unlock for cloud execution AND the durable fix for the cross-repo corruption
+> class — it should lead the roadmap.

+# How mini-ork reduces "surprise" for the researcher app — DB analysis (2026-07-01)
+
+Source: `/Volumes/docker-ssd/Migration/Development/researcher/.mini-ork/state.db`
+(264 `task_runs`, 2026-06-10 → 2026-06-30).
+
+## TL;DR
+mini-ork's least-surprise value for researcher today is **containment**, not
+improvement: ~95% of run churn dies inside its sandbox/worktrees and never touches
+the app. But two gaps mean it *contains* surprise without yet *reducing* it — and a
+chunk of the "failure" is mini-ork's own instability, i.e. **added** surprise.
+
+## 1. Outcome distribution — the containment story
+| status | n | note |
+|---|---|---|
+| failed | 119 | caught in-run |
+| failed / CRASH | 76 | **engine crash (self-inflicted)** |
+| classified only | 43 | abandoned before execute |
+| executing (stale) | 30 | **zombie: crashed w/o status finalization** |
+| published | **14** | reached the app |
+| planned / reviewing | 4 | in-flight |
+
+Only **14 / 264 (5.3%)** published. The other 95% — failed, abandoned, or stale —
+were absorbed by the orchestrator. Verifier/reviewer/rollback gates mean nothing
+merges unverified: **the surprises happen in a blast-shielded runner, not in
+production.** That is the core mechanism by which mini-ork lets researcher get built
+with the least production surprise: trade lots of cheap, contained, sandboxed
+failure for very few app-level surprises.
+
+## 2. The DB *is* updated per run — with two write-back gaps
+The 264 rows are real recorded outcomes (the numbers above come straight from them),
+so it's NOT that the DB isn't updated. But:
+- **30 stale `executing` rows** = runs that crashed/were-killed without the status
+  being flipped to `failed`. Abnormal-exit status finalization is missing (same
+  crash/corruption class as I-5/I-7/I-16). A dying run orphans its own status row.
+- **The learning half of the DB is empty.** `gradient_records` = **8,951** (extraction
+  works, growing ~900→3,700/week) but `emergent_patterns` = `pattern_records` =
+  `promotion_records` = **0**. mini-ork records *what happened* and even *what could
+  improve*, but the reflect→**improve→promote** step never writes back.
+
+## 3. What it's learning about (gradient targets, top)
+| target | signals |
+|---|---|
+| `workflow.recipe.code_fix` | 397 |
+| `workflow.node.planner` | 367 |
+| `workflow.recipe.framework_edit` | 258 |
+| `verifier.*` | ~470 |
+| `workflow.node.implementer` | 205 |
+| planner/implementer→verifier edges | ~386 |
+
+~9,000 targeted improvement signals, concentrated exactly on the weak spots — a rich
+map for GEPA/GRPO to reduce future surprise. It's just not being consumed.
+
+## 4. Surprise is contained, not declining (the honest caveat)
+Weekly published/failed: W23 5/31 · W24 0/41 · W25 5/81 · W26 4/42. The failure rate
+stays flat (~60–75%) — because the learning loop doesn't close (§2). And 76 CRASHes
+(epic-runner 16, code-fix 15, framework-edit 14, refactor-audit 11) are mini-ork's own
+bugs, not real catches — **added** surprise, the class the I-5/I-7/I-16 fixes + sandbox
+isolation shipped this session directly attack.
+
+## 5. So: how mini-ork helps build with least surprise
+- **Primary (working): containment.** Verifier-gated, sandboxed, rollback-on-fail →
+  95% of attempts never reach the app. Nothing ships un-gated.
+- **Secondary (built, unused): a 9k-signal learning corpus** aimed at its weak spots.
+- **Cost: engine instability** injects self-inflicted surprise (crashes / stale status).
+
+## 6. The next levers (to make surprise actually *decline*, not just be contained)
+1. **Close the learning loop write-back** — synthesize `gradient_records` into
+   `emergent_patterns` → `promotion_records` and feed promoted prompts back (this is
+   exactly what the GEPA wiring, R4b, + the reflect→improve→promote path should do;
+   verify it runs and populates these tables in researcher). Highest lever.
+2. **Finalize status on abnormal exit** — a reaper that flips stale `executing` →
+   `failed`/`crashed` so the ledger is truthful (also fixes the 30 zombies).
+3. **Kill the self-inflicted CRASH class** — the engine fixes + per-agent sandbox
+   from this session; re-measure the CRASH share after they sync into researcher.
+
+**Net:** mini-ork already buys researcher "few production surprises" via containment.
+Turning that into "fewer surprises over time" needs the learning loop to actually
+close — collecting 9,000 lessons and acting on none is the biggest missed lever.

+# Implementation analysis — how leaders build what mini-ork lacks (2026-06-30)
+
+Source-level analysis of cloned, real OSS repos, each mapped to a mini-ork gap and a concrete
+adoption plan. Companion to `../2026-06-30-similar-orchestrators-and-agent-sandboxing.md` (survey)
+and `../../../docs/audits/20260630-miniork-fix-tracker.md` (issue tracker, esp. **A1**).
+
+Repos cloned to `/private/tmp/miniork-ref-analysis/` (shallow): mini-swe-agent, swe-rex,
+e2b code-interpreter, OpenHands, gepa, mem0, llm-council.
+
+## The docs
+
+| # | Doc | Repos | mini-ork gap | Recs |
+|---|---|---|---|---|
+| 01 | `01-runtime-sandbox-swerex-minisweagent.md` | mini-swe-agent + swe-rex | **A1** — host-FS execution, no runtime/sandbox seam | R0/R1/R2 |
+| 02 | `02-managed-sandbox-e2b-openhands.md` | E2B + OpenHands | managed cloud sandbox + controller/runtime split | R3 |
+| 03 | `03-gepa-reflective-optimization.md` | GEPA | optimization cheaper/better than GRPO | R4 |
+| 04 | `04-mem0-semantic-memory.md` | mem0 | semantic/long-term memory (vs SQL run-log) | — |
+| 05 | `05-llm-council-panel-bias.md` | llm-council | panel anonymization + arbiter bias controls | I-1/I-6 |
+
+## The one pattern that recurs (docs 01 + 02)
+swe-rex, OpenHands, and E2B independently converge on the SAME shape, and it's exactly what
+mini-ork lacks:
+1. **One exec seam** the agent calls (`execute(action,cwd)`), backend-agnostic.
+2. **Stateless actions** (subprocess-per-action) → swapping local→`docker exec`→microVM is a
+   backend change, not a rewrite.
+3. **Agent/runtime server runs *inside* the sandbox, reached over HTTP** → local==remote to the
+   controller.
+4. **Workspace moves by archive/file-transfer**, not a shared disk.
+5. **Typed sandbox lifecycle** (start/wait-alive/pause/resume/delete) + pooling for cost.
+
+mini-ork's `bin/mini-ork-execute` does the opposite (stateful host `cd`+`bash`, shared disk) —
+which is why it can't go cloud and why a stray process clobbered a sibling repo.
+
+## Recommended build sequence (highest leverage first)
+1. **R0 — stateless exec seam** (`lib/runtime/contract.sh`: `mo_env_exec/put/get`); refactor
+   `bin/mini-ork-execute` to call it; steal mini-swe-agent's process-group-kill-on-timeout.
+   *Prerequisite for everything; a refactor, not new infra.*
+2. **R2 — bubblewrap backend** (`lib/runtime/bubblewrap.sh`): only the workspace is writable →
+   structurally prevents the cross-repo clobber. Cheap, no daemon (Linux/CI/cloud; keep `local`
+   on macOS dev).
+3. **R3 — docker → managed (E2B/Daytona)**: mini-ork agent-server-in-sandbox over HTTP +
+   workspace archive (docs 02). Unlocks true cloud.
+4. **R4 — GEPA reflective optimizer** alongside GRPO (`MO_OPTIMIZER=gepa`): minibatch-acceptance
+   gate → ~35× fewer rollouts → attacks the cost circuit (I-4). Adapter = 2 methods over the
+   existing trace store.
+5. **Semantic memory (mem0 pattern)**: `lib/semantic_memory.sh` + sqlite-vec; extract learnings
+   at reflect, retrieve at plan/context-assembly. Cross-run learning by meaning.
+6. **Panel bias controls (llm-council)**: anonymized cross-review + position randomization +
+   rank-aggregation into the existing gates (I-1 quorum dimension, I-6 bias).
+
+R0→R2→R3 is the A1/cloud spine and should lead; R4/memory/panel are independent quality tracks.
+
+## Status
+All five analyses are documented. Next step (not yet done): turn R0→R3 into a scoped epic/design
+and implement via mini-ork's own pipeline (per the 2+-file dispatch rule), once the dispatch
+vehicle is trusted (note: framework-edit verdict.json was fixed — I-5 — and the code-fix
+test-gate was fixed — I-7 — so dispatches should now land cleanly).

+# Runtime & Sandbox Abstraction: Source-Code Analysis
+## References: mini-swe-agent + swe-rex — Adoption Plan for mini-ork
+
+**Date:** 2026-06-30  
+**Scope:** A1 gap — mini-ork agents run directly on the host OS filesystem (`bin/mini-ork-execute`
+`cd`s into repos and runs bash/CLI on the host). No per-agent sandbox, no runtime abstraction.
+Blocks cloud execution; caused cross-repo git corruption.
+
+**Sources analyzed (real code, no docs):**
+- `/private/tmp/miniork-ref-analysis/mini-swe-agent` (v2.4.3) — Python ~100-line agent, stateless `subprocess.run`-per-action, ships local/docker/bubblewrap/singularity backends
+- `/private/tmp/miniork-ref-analysis/swe-rex` — "run any command on any environment — local/Docker/Modal/AWS/Daytona"; runtime-interface + deployment abstraction powering SWE-agent
+
+---
+
+## 1. The Runtime / Exec Abstraction
+
+### 1.1 mini-swe-agent: Single `execute(action, cwd)` Interface
+
+mini-swe-agent's entire execution contract is one method, implemented by every backend:
+
+```python
+# src/minisweagent/environments/local.py — signature repeated identically in docker.py, bubblewrap.py, singularity.py
+def execute(self, action: dict, cwd: str = "", *, timeout: int | None = None) -> dict[str, Any]:
+    command = action.get("command", "")
+    cwd = cwd or self.config.cwd or os.getcwd()
+    result = _run(command, cwd, os.environ | self.config.env, timeout or self.config.timeout)
+    output = {"output": result.stdout, "returncode": result.returncode, "exception_info": ""}
+    self._check_finished(output)
+    return output
+```
+
+Returns `{"output": str, "returncode": int, "exception_info": str}`. The **agent loop** in `agents/default.py` calls it without knowing which backend is active:
+
+```python
+# agents/default.py:152-155
+def execute_actions(self, message: dict) -> list[dict]:
+    outputs = [self.env.execute(action) for action in message.get("extra", {}).get("actions", [])]
+    return self.add_messages(*self.model.format_observation_messages(message, outputs, self.get_template_vars()))
+```
+
+**Statelessness:** Every `execute()` call creates a fresh subprocess — no persistent shell state between calls. The `cwd` is passed per-call; it is not ambient process state. The local backend's `_run` helper starts a new session and kills the whole process group on timeout:
+
+```python
+# environments/local.py:72-92  — process-group kill prevents orphans
+process = subprocess.Popen(command, shell=True, text=True, cwd=cwd, env=env,
+    stdout=subprocess.PIPE, stderr=subprocess.STDOUT,
+    start_new_session=os.name == "posix")
+try:
+    stdout, _ = process.communicate(timeout=timeout)
+except subprocess.TimeoutExpired:
+    os.killpg(process.pid, signal.SIGKILL) if os.name == "posix" else process.kill()
+    stdout, _ = process.communicate()
+    raise subprocess.TimeoutExpired(command, timeout, output=stdout)
+```
+
+### 1.2 swe-rex: Two-Layer Interface (Deployment + Runtime)
+
+swe-rex splits the concern: **what** runs (runtime) vs **where** it runs and its lifecycle (deployment).
+
+#### AbstractRuntime (`src/swerex/runtime/abstract.py`)
+
+```python
+class AbstractRuntime(ABC):
+    async def is_alive(self, *, timeout=None) -> IsAliveResponse: ...
+    async def create_session(self, request: CreateSessionRequest) -> CreateSessionResponse: ...
+    async def run_in_session(self, action: Action) -> Observation: ...
+    async def close_session(self, request: CloseSessionRequest) -> CloseSessionResponse: ...
+    async def execute(self, command: Command) -> CommandResponse: ...
+    async def read_file(self, request: ReadFileRequest) -> ReadFileResponse: ...
+    async def write_file(self, request: WriteFileRequest) -> WriteFileResponse: ...
+    async def upload(self, request: UploadRequest) -> UploadResponse: ...
+    async def close(self) -> CloseResponse: ...
+```
+
+Two execution paths coexist:
+- **Stateless** (`execute`): one-shot subprocess, like `subprocess.run`. Takes `Command(command, cwd, env, timeout, shell, check)`.
+- **Stateful sessions** (`create_session` / `run_in_session`): a persistent bash REPL managed via `pexpect`. `BashSession` (in `runtime/local.py`) spawns `/usr/bin/env bash`, sends commands, reads until PS1 returns. Multiple named sessions coexist. Exit codes are extracted by injecting `echo EXITCODESTART$?EXITCODEEND` and parsing the sentinel:
+
+```python
+# runtime/local.py:324-337 — reliable exit code extraction in a stateful REPL
+self.shell.sendline(f"\necho {_exit_code_prefix}$?{_exit_code_suffix}")
+self.shell.expect(_exit_code_suffix, timeout=1)
+exit_code_raw: str = _strip_control_chars(self.shell.before)
+exit_code = re.findall(f"{_exit_code_prefix}([0-9]+)", exit_code_raw)
+```
+
+#### AbstractDeployment (`src/swerex/deployment/abstract.py`)
+
+```python
+class AbstractDeployment(ABC):
+    async def start(self, *args, **kwargs): ...      # boot the sandbox (+ start runtime server inside)
+    async def stop(self, *args, **kwargs): ...       # teardown
+    async def is_alive(self, *, timeout=None) -> IsAliveResponse: ...
+    @property
+    def runtime(self) -> AbstractRuntime: ...        # returns the runtime to use
+    def add_hook(self, hook: DeploymentHook): ...    # status callbacks
+```
+
+The agent code only touches `deployment.runtime.execute(...)` or `deployment.runtime.run_in_session(...)`. The deployment class is responsible for making that runtime callable — whether local, in a container, or on Modal cloud.
+
+---
+
+## 2. Each Sandbox Backend
+
+### 2.1 mini-swe-agent Backends
+
+#### LocalEnvironment (`environments/local.py`)
+
+No isolation. `subprocess.Popen(command, shell=True, cwd=cwd, env=env, start_new_session=True)`. Workspace = host filesystem at `cwd`. No namespace separation.
+
+#### DockerEnvironment (`environments/docker.py`)
+
+Boot (`__init__` → `_start_container`):
+```python
+# environments/docker.py:76-99
+cmd = [self.config.executable, "run", "-d", "--name", container_name,
+       "-w", self.config.cwd, *self.config.run_args, self.config.image,
+       "sleep", self.config.container_timeout]
+result = subprocess.run(cmd, capture_output=True, text=True, timeout=self.config.pull_timeout, check=True)
+self.container_id = result.stdout.strip()
+```
+
+Execute (per-call):
+```python
+# environments/docker.py:107-113
+cmd = [self.config.executable, "exec", "-w", cwd]
+for key, value in self.config.env.items():
+    cmd.extend(["-e", f"{key}={value}"])
+cmd.extend([self.container_id, *self.config.interpreter, command])
+# interpreter default: ["bash", "-lc"]
+```
+
+Container started once, reused for all `execute()` calls. Teardown: async `docker stop || docker rm -f` via `Popen(..., shell=True)` (non-blocking).
+
+#### BubblewrapEnvironment (`environments/extra/bubblewrap.py`)
+
+Creates a per-instance tmpdir workspace on init:
+```python
+# environments/extra/bubblewrap.py:78-79
+self.working_dir = Path(tempfile.gettempdir()) / f"minisweagent-{uuid.uuid4().hex[:8]}"
+self.working_dir.mkdir(parents=True, exist_ok=True)
+```
+
+Execute — builds the `bwrap` command per-call:
+```python
+# environments/extra/bubblewrap.py:86-92
+cmd = [self.config.executable] + self.config.wrapper_args + ["--bind", cwd, cwd, "--chdir", cwd]
+for key, value in self.config.env.items():
+    cmd.extend(["--setenv", key, value])
+cmd.extend(["bash", "-c", command])
+```
+
+Default `wrapper_args`:
+```python
+["--unshare-user-try",
+ "--ro-bind", "/usr", "/usr",  "--ro-bind", "/bin", "/bin",
+ "--ro-bind", "/lib", "/lib",  "--ro-bind", "/lib64", "/lib64",
+ "--ro-bind", "/etc", "/etc",
+ "--tmpfs", "/tmp",  "--proc", "/proc",  "--dev", "/dev",
+ "--new-session",
+ "--setenv", "PATH", "/usr/local/bin:/usr/sbin:/usr/bin:/bin"]
+```
+
+**Key isolation facts:**
+- Entire host is **read-only** (`--ro-bind`)
+- `/tmp` is a **fresh tmpfs per call** (not shared between calls)
+- Only `--bind cwd cwd` is writable — the agent's workspace
+- `--unshare-user-try` = unprivileged user namespaces, no root needed
+- No persistent container — each `execute()` spawns a fresh `bwrap` process
+
+Teardown: `shutil.rmtree(self.working_dir)`.
+
+#### SingularityEnvironment (`environments/singularity.py`)
+
+Boot: `singularity build --sandbox <tmpdir> <image>` — converts image into a writable sandbox directory on host:
+```python
+# environments/singularity.py:46-65
+sandbox_dir = Path(tempfile.gettempdir()) / f"minisweagent-{uuid.uuid4().hex[:8]}"
+subprocess.run([self.config.executable, "build", "--sandbox", sandbox_dir, self.config.image], ...)
+```
+
+Execute:
+```python
+# environments/singularity.py:82-96
+cmd = [self.config.executable, *self.config.global_args, "exec", *self.config.exec_args]
+# exec_args default: ["--contain", "--cleanenv", "--fakeroot", "--writable"]
+if work_dir and work_dir != "/":
+    cmd.extend(["--pwd", work_dir])
+cmd.extend(["--writable", str(self.sandbox_dir), "bash", "-c", command])
+```
+
+`--contain` prevents host home/tmp leaking in. `--cleanenv` scrubs host env. `--fakeroot` gives apparent root. `--writable` allows writes to sandbox. Sandbox dir is durable — all calls share the same mutable filesystem state.
+
+Teardown: `shutil.rmtree(self.sandbox_dir)`.
+
+### 2.2 swe-rex Backends
+
+#### LocalDeployment (`deployment/local.py`)
+
+`start()` instantiates `LocalRuntime(logger=...)`. The `runtime` property returns it directly. No isolation.
+
+#### LocalRuntime (`runtime/local.py`)
+
+`execute(command)` → stateless `subprocess.run`. `create_session` spawns `BashSession` (pexpect). `read_file` / `write_file` / `upload` operate on the local filesystem.
+
+#### DockerDeployment (`deployment/docker.py`) — critical difference from mini-swe-agent
+
+swe-rex does **not** use `docker exec` for commands. It installs a `swerex-server` HTTP server **inside** the container and communicates via HTTP:
+
+```python
+# deployment/docker.py:252-282 — start()
+token = self._get_token()
+cmds = [self._config.container_runtime, "run", "--rm",
+        "-p", f"{self._config.port}:8000",
+        *self._config.docker_args, "--name", self._container_name, image_id,
+        *self._get_swerex_start_cmd(token)]
+# _get_swerex_start_cmd = ["/bin/sh", "-c", "swerex-server --auth-token <token>"]
+self._container_process = subprocess.Popen(cmds, stdout=PIPE, stderr=PIPE)
+self._runtime = RemoteRuntime.from_config(
+    RemoteRuntimeConfig(host="http://127.0.0.1", port=self._config.port, auth_token=token))
+await self._wait_until_alive(timeout=self._config.startup_timeout)
+```
+
+The container runs the swerex server. The client talks to it over HTTP. `docker exec` is never used after boot.
+
+#### RemoteRuntime (`runtime/remote.py`)
+
+Every method is an async HTTP POST to the swerex server with exponential-backoff retry:
+
+```python
+# runtime/remote.py:165-196 — _request()
+async with aiohttp.ClientSession(...) as session:
+    async with session.post(f"{self._api_url}/{endpoint}",
+                            json=payload.model_dump(), headers=headers) as resp:
+        await self._handle_response_errors(resp)
+        return output_class(**await resp.json())
+```
+
+Auth via `X-API-Key` header. Exceptions serialized as `_ExceptionTransfer` and re-raised on client. `upload()` uses multipart form-data (zips directories).
+
+#### ModalDeployment (`deployment/modal.py`)
+
+```python
+# deployment/modal.py:220-246 — start()
+self._sandbox = await modal.Sandbox.create.aio(
+    "/usr/bin/env", "bash", "-c", self._start_swerex_cmd(token),
+    image=self._image, timeout=int(self._deployment_timeout),
+    unencrypted_ports=[self._port], app=self._app, **self._modal_kwargs)
+tunnels = await self._sandbox.tunnels.aio()
+tunnel = tunnels[self._port]
+self._runtime = RemoteRuntime(host=tunnel.url, timeout=self._runtime_timeout, auth_token=token)
+```
+
+Modal/Fargate/Daytona all follow the same pattern: boot a container, start swerex-server inside it, expose a URL, create `RemoteRuntime` pointing to that URL. From the agent's perspective, `deployment.runtime.execute(...)` is identical regardless of whether the sandbox is local, Modal, or Fargate.
+
+---
+
+## 3. Backend Selection (Config / Factory)
+
+### mini-swe-agent
+
+`src/minisweagent/environments/__init__.py`:
+
+```python
+_ENVIRONMENT_MAPPING = {
+    "docker":        "minisweagent.environments.docker.DockerEnvironment",
+    "singularity":   "minisweagent.environments.singularity.SingularityEnvironment",
+    "local":         "minisweagent.environments.local.LocalEnvironment",
+    "swerex_docker": "minisweagent.environments.extra.swerex_docker.SwerexDockerEnvironment",
+    "swerex_modal":  "minisweagent.environments.extra.swerex_modal.SwerexModalEnvironment",
+    "bubblewrap":    "minisweagent.environments.extra.bubblewrap.BubblewrapEnvironment",
+}
+
+def get_environment(config: dict, *, default_type: str = "") -> Environment:
+    config = copy.deepcopy(config)
+    environment_class = config.pop("environment_class", default_type)
+    return get_environment_class(environment_class)(**config)
+```
+
+Selection by `environment_class` field in the YAML config. CLI flag `--environment-class` overrides. The benchmark runner passes `environment_class: docker` (or `singularity`, `bubblewrap`, etc.) at dispatch time; the agent code does not change.
+
+### swe-rex
+
+`src/swerex/deployment/config.py` defines a `DeploymentConfig` union with a `type` discriminator:
+
+```python
+DeploymentConfig = (
+    LocalDeploymentConfig | DockerDeploymentConfig | ModalDeploymentConfig
+    | FargateDeploymentConfig | RemoteDeploymentConfig | DaytonaDeploymentConfig
+)
+
+def get_deployment(config: DeploymentConfig) -> AbstractDeployment:
+    return config.get_deployment()   # each config class implements get_deployment()
+```
+
+```python
+class DockerDeploymentConfig(BaseModel):
+    type: Literal["docker"] = "docker"    # discriminator
+    image: str = "python:3.11"
+    ...
+    def get_deployment(self) -> AbstractDeployment:
+        from swerex.deployment.docker import DockerDeployment
+        return DockerDeployment.from_config(self)
+```
+
+A single YAML key `type: docker` selects the entire backend stack (boot, runtime, teardown). The agent never changes.
+
+---
+
+## 4. Parallelism
+
+### mini-swe-agent
+
+`src/minisweagent/run/benchmarks/swebench.py`:
+
+```python
+# swebench.py:256-262
+with concurrent.futures.ThreadPoolExecutor(max_workers=workers) as executor:
+    futures = {
+        executor.submit(process_instance, instance, output_dir, config, progress_manager)
+        for instance in instances
+    }
+```
+
+Each `process_instance` call creates its own `env = get_sb_environment(config, instance)` — a fresh `DockerEnvironment` with its own container — and its own `DefaultAgent`. Each container is isolated; agents cannot corrupt each other's filesystems. The only shared resource is the host Docker daemon socket. A file-level mutex (`_OUTPUT_FILE_LOCK`) serializes writes to the shared predictions JSON.
+
+**Parallelism degree:** `--workers N` CLI flag.
+
+### swe-rex
+
+swe-rex is a library; parallelism is the caller's responsibility. Because `RemoteRuntime` is just a host+port+token struct, multiple independent callers can create independent deployments and run them concurrently without interference even on the same host.
+
+---
+
+## 5. mini-ork Current State (What Exists, What's Missing)
+
+### What Exists
+
+mini-ork has `lib/sandbox/` with a 4-function contract:
+- `mo_sandbox_<backend>_provision <child_run_id>` → workspace path
+- `mo_sandbox_<backend>_dispatch <workspace> <recipe> <kickoff>`
+- `mo_sandbox_<backend>_retrieve <workspace> <run_dir>`
+- `mo_sandbox_<backend>_cleanup <workspace>`
+
+Backends: `local.sh` (complete), `modal.sh` (stub — falls back to local), `daytona.sh` (stub — falls back to local).
+
+### The Gap
+
+`lib/sandbox/` covers **run-level provisioning** (where to put artifacts). It does NOT intercept **command-level execution** (how individual bash commands and LLM calls actually run). The true execution path is:
+
+1. `bin/mini-ork-execute` parses `plan.json`/`workflow.yaml` and dispatches node types.
+2. Per node it calls `lib/llm-dispatch.sh:mo_llm_dispatch <model> <prompt> <output>` — which sources a `cl_*.sh` wrapper and then runs `claude --print`/`kimi`/etc. directly on the **host process**, inheriting all env and cwd.
+3. Verifiers run as `( cd "$_verify_cwd" && bash "$_script" )` on the **host filesystem** (line 114 of `bin/mini-ork-execute`).
+4. The implementer writes files via Claude's Edit/Write tools, which write directly into the **host git worktree** (`$MO_TARGET_CWD`).
+
+**There is no intercept point between "node dispatched" and "bash command runs on host."** The modal/daytona adapters in `lib/sandbox/` never actually send commands into a container; `mo_sandbox_modal_dispatch` calls `mo_sandbox_local_dispatch` which still does `cd "$_workspace" && mini-ork run ...` on the host.
+
+The cross-repo git clobber happened because two implementer nodes running in `parallel` dispatch mode both `cd`'d into the same target repo and issued git commands — no filesystem isolation existed to prevent it.
+
+---
+
+## 6. Adoption Plan
+
+### R0 — Stateless Exec Through One Function (1–2 days, pure bash, zero new deps)
+
+**Goal:** Introduce `mo_runtime_exec` as the single execution seam. Refactor every naked `cd + bash` pattern to call it. No isolation yet — just the hook point.
+
+**New file:** `lib/runtime/local.sh`
+
+```bash
+#!/usr/bin/env bash
+# lib/runtime/local.sh — local (no-isolation) runtime backend.
+# Implements the mo_runtime_exec/put/get contract for the host filesystem.
+# This is the R0 baseline: same behavior as today, but through an explicit seam.
+
+mo_runtime_exec() {
+  local _cmd="$1"
+  local _cwd="${2:-$PWD}"
+  local _timeout="${3:-120}"
+  # Run in a subshell so env/cwd changes don't propagate.
+  # Use setsid + process-group kill (matches mini-swe-agent's orphan fix).
+  ( cd "$_cwd" && timeout "$_timeout" bash -c "$_cmd" )
+}
+
+mo_runtime_put() { local _src="$1" _dst="$2"; cp -R "$_src" "$_dst"; }
+mo_runtime_get()  { local _src="$1" _dst="$2"; cp -R "$_src" "$_dst"; }
+
+# Sessions: no-op for local backend (each exec is already independent)
+mo_runtime_session_create() { : ; }
+mo_runtime_session_run() {
+  local _session_id="$1" _cmd="$2" _cwd="${3:-$PWD}"
+  mo_runtime_exec "$_cmd" "$_cwd"
+}
+mo_runtime_session_close() { : ; }
+```
+
+**New file:** `lib/runtime.sh` (router, sourced by mini-ork-execute at startup):
+
+```bash
+#!/usr/bin/env bash
+# lib/runtime.sh — runtime backend router.
+MO_RUNTIME_BACKEND="${MO_RUNTIME_BACKEND:-local}"
+source "${MINI_ORK_ROOT}/lib/runtime/${MO_RUNTIME_BACKEND}.sh"
+```
+
+**Change to `bin/mini-ork-execute`** startup block (after existing `_require_lib` calls):
+```bash
+source "$MINI_ORK_ROOT/lib/runtime.sh"
+```
+
+**Change to `_run_verifier_ref`** (replaces line 114):
+```bash
+# Before:
+( cd "$_verify_cwd" && MINI_ORK_PLAN_PATH="$PLAN_PATH" ARTIFACT_PATH="$ARTIFACT_PATH" \
+  bash "$_script" ) > "$_evidence" 2>&1
+
+# After:
+MINI_ORK_PLAN_PATH="$PLAN_PATH" ARTIFACT_PATH="$ARTIFACT_PATH" \
+  mo_runtime_exec "bash $(realpath "$_script")" "$_verify_cwd" \
+  > "$_evidence" 2>&1
+```
+
+### R1 — Runtime Interface Contract (1 day)
+
+**Define the 6-function bash contract** (maps directly to swe-rex's `AbstractRuntime`):
+
+| Bash function | Signature | Analogous to |
+|---|---|---|
+| `mo_runtime_exec` | `<cmd> <cwd> [timeout]` | `AbstractRuntime.execute(Command)` |
+| `mo_runtime_put` | `<src_path> <dst_path>` | `AbstractRuntime.upload(UploadRequest)` |
+| `mo_runtime_get` | `<src_path> <dst_path>` | `AbstractRuntime.read_file(ReadFileRequest)` |
+| `mo_runtime_session_create` | `<session_id> [startup_cmd]` | `AbstractRuntime.create_session(...)` |
+| `mo_runtime_session_run` | `<session_id> <cmd> [cwd]` | `AbstractRuntime.run_in_session(Action)` |
+| `mo_runtime_session_close` | `<session_id>` | `AbstractRuntime.close_session(...)` |
+
+All backends implement these 6 functions. The router in `lib/runtime.sh` sources one backend file based on `MO_RUNTIME_BACKEND`. The caller code (`bin/mini-ork-execute`, `lib/llm-dispatch.sh`, verifier dispatch) never changes when the backend changes.
+
+Session state for backends with persistent containers: store the handle (container name, pexpect PID) in a temp file keyed by session ID: `/tmp/mo-session-${session_id}.container`.
+
+### R2a — Bubblewrap Backend (2–3 days, Linux-only, no root, stops the clobber today)
+
+**New file:** `lib/runtime/bubblewrap.sh`
+
+```bash
+#!/usr/bin/env bash
+# lib/runtime/bubblewrap.sh — unprivileged Linux sandbox via bwrap.
+# Mirrors mini-swe-agent BubblewrapEnvironment exactly.
+# Requires: bubblewrap (bwrap), Linux kernel with user namespaces.
+
+_MO_BWRAP="${MO_BWRAP_EXECUTABLE:-bwrap}"
+
+_mo_bwrap_base_args() {
+  # System paths read-only; workspace is the only writable bind.
+  printf '%s\0' \
+    --unshare-user-try \
+    --ro-bind /usr /usr \
+    --ro-bind /bin /bin \
+    --ro-bind-try /lib /lib \
+    --ro-bind-try /lib64 /lib64 \
+    --ro-bind /etc /etc \
+    --tmpfs /tmp \
+    --proc /proc \
+    --dev /dev \
+    --new-session \
+    --setenv PATH /usr/local/bin:/usr/sbin:/usr/bin:/bin
+}
+
+mo_runtime_exec() {
+  local _cmd="$1"
+  local _cwd="${2:-$PWD}"
+  local _timeout="${3:-120}"
+
+  mkdir -p "$_cwd"
+
+  local _bwrap_args=()
+  while IFS= read -r -d '' _arg; do
+    _bwrap_args+=("$_arg")
+  done < <(_mo_bwrap_base_args)
+
+  timeout "$_timeout" "$_MO_BWRAP" \
+    "${_bwrap_args[@]}" \
+    --bind "$_cwd" "$_cwd" \
+    --chdir "$_cwd" \
+    bash -c "$_cmd"
+}
+
+# bwrap has no persistent container; put/get are host-side copies.
+mo_runtime_put() { local _src="$1" _dst="$2"; cp -R "$_src" "$_dst"; }
+mo_runtime_get()  { local _src="$1" _dst="$2"; cp -R "$_src" "$_dst"; }
+
+# Each bwrap exec is already stateless; sessions are no-op.
+mo_runtime_session_create() { : ; }
+mo_runtime_session_run() {
+  local _session_id="$1" _cmd="$2" _cwd="${3:-$PWD}"
+  mo_runtime_exec "$_cmd" "$_cwd"
+}
+mo_runtime_session_close() { : ; }
+```
+
+**Isolation achieved:** Each `mo_runtime_exec` call gets:
+- System paths (`/usr`, `/bin`, `/lib`, `/etc`) read-only from host
+- `/tmp` as a fresh tmpfs — ephemeral, not shared between calls
+- Only the explicit workspace dir (`_cwd`) is bind-mounted read-write
+- No root required (`--unshare-user-try` uses kernel user namespaces)
+
+The workspace is the run's directory under `$MINI_ORK_HOME/runs/<run_id>/workspace/`, provisioned by the existing `lib/sandbox/local.sh:mo_sandbox_local_provision`. Implementer writes go into this workspace, not into the target repo's main checkout.
+
+**macOS note:** bwrap is Linux-only. The local backend remains the macOS fallback (`MO_RUNTIME_BACKEND=local`). Use bubblewrap in CI and cloud.
+

+
+**New file:** `lib/runtime/docker.sh`
+
+```bash

+```
+
+### R2c — swerex Bridge for Cloud (Phase 2, 1 week)
+
+For Modal/Fargate/Daytona, mini-ork can shell out to a Python helper that wraps `swerex.deployment.*` rather than reimplementing cloud SDKs in bash.
+
+**New file:** `lib/runtime/swerex_bridge.sh`
+
+```bash
+#!/usr/bin/env bash
+# lib/runtime/swerex_bridge.sh — delegates all exec to swe-rex Python runtime.
+# Requires: pip install swe-rex, set MO_SWEREX_DEPLOYMENT_TYPE (local|docker|modal|fargate).
+
+mo_runtime_exec() {
+  local _cmd="$1" _cwd="${2:-$PWD}" _timeout="${3:-120}"
+  python3 "$MINI_ORK_ROOT/lib/runtime/swerex_exec.py" \
+    --deployment-type "${MO_SWEREX_DEPLOYMENT_TYPE:-docker}" \
+    --image "${MO_SWEREX_IMAGE:-ubuntu:22.04}" \
+    --cwd "$_cwd" --timeout "$_timeout" --cmd "$_cmd"
+}
+```
+
+`lib/runtime/swerex_exec.py` (thin wrapper):
+```python
+import asyncio, argparse
+from swerex.deployment.config import get_deployment, DockerDeploymentConfig, ModalDeploymentConfig
+from swerex.runtime.abstract import Command
+
+async def main(args):
+    config = {
+        "docker": DockerDeploymentConfig(image=args.image),
+        "modal": ModalDeploymentConfig(image=args.image),
+    }[args.deployment_type]
+    dep = config.get_deployment()
+    await dep.start()
+    result = await dep.runtime.execute(Command(
+        command=args.cmd, cwd=args.cwd, timeout=args.timeout, shell=True, merge_output_streams=True))
+    await dep.stop()
+    print(result.stdout, end="")
+
+asyncio.run(main(argparse.ArgumentParser().parse_args()))
+```
+
+This reuses swe-rex's entire Modal/Fargate stack — `ModalDeployment.start()` creates the sandbox and returns a `RemoteRuntime` talking to the swerex HTTP server inside it — without any bash reimplementation of the Modal SDK.
+
+---
+
+## 7. Changes to `bin/mini-ork-execute`
+
+### Current problematic patterns
+
+**Pattern 1 — verifier runs directly on host (line ~114):**
+```bash
+( cd "$_verify_cwd" && MINI_ORK_PLAN_PATH="$PLAN_PATH" ARTIFACT_PATH="$ARTIFACT_PATH" \
+  bash "$_script" ) > "$_evidence" 2>&1
+```
+
+**Pattern 2 — node dispatch in subshell (in lib/llm-dispatch.sh):**
+```bash
+( source "$MINI_ORK_ROOT/lib/$cl_script" && claude --print ... )
+```
+
+**Pattern 3 — implementer writes directly to host worktree** via Claude's Edit/Write tool calls, operating on `$MO_TARGET_CWD`.
+
+### Changes
+
+Add to `bin/mini-ork-execute` startup (after existing lib sources, before `PLAN_PATH` resolution):
+```bash
+source "$MINI_ORK_ROOT/lib/runtime.sh"
+```
+
+Refactor `_run_verifier_ref`:
+```bash
+# Replace the inline subshell (line ~114):
+MINI_ORK_PLAN_PATH="$PLAN_PATH" ARTIFACT_PATH="$ARTIFACT_PATH" \
+  mo_runtime_exec "bash $(realpath "$_script")" "$_verify_cwd" \
+  > "$_evidence" 2>&1
+_exit=$?
+# ... json parse and return unchanged ...
+```
+
+For parallel nodes, key each node's workspace to its `node_id` so they don't share a workspace dir:
+```bash
+_node_workspace="$RUN_DIR/workspaces/$_node_id"
+mkdir -p "$_node_workspace"
+# Then all mo_runtime_exec calls for this node use $_node_workspace as cwd
+```
+
+---
+
+## 8. Backend Selection in mini-ork
+
+### Environment variable (immediate):
+```bash
+MO_RUNTIME_BACKEND=bubblewrap mini-ork run recipe kickoff.md
+MO_RUNTIME_BACKEND=docker MO_DOCKER_IMAGE=ubuntu:22.04 mini-ork run recipe kickoff.md
+MO_RUNTIME_BACKEND=swerex_bridge MO_SWEREX_DEPLOYMENT_TYPE=modal mini-ork run recipe kickoff.md
+```
+
+### Per-run config in workflow.yaml (Phase 2):
+```yaml
+runtime:
+  backend: bubblewrap     # or: local | docker | swerex_bridge
+  docker_image: ubuntu:22.04
+  workspace_mount: /workspace
+```
+
+`lib/config_resolve.sh:mo_snapshot_run_config` already snapshots config into `$RUN_DIR`. Runtime backend gets added to the snapshot and exported as `MO_RUNTIME_BACKEND`.
+
+### Fallback chain (mirrors swe-rex's graceful degradation):
+```
+bubblewrap → if bwrap absent → local
+docker     → if docker absent → local
+swerex_bridge → if swe-rex absent → docker → local
+```
+
+---
+
+## 9. Parallelism
+
+mini-ork's `parallel` dispatch mode already runs multiple nodes via background jobs. The missing piece is that parallel nodes share the same host filesystem — they can corrupt each other's git state.
+
+With the runtime interface:
+- Each parallel node gets its own workspace via a per-node workspace dir (`$RUN_DIR/workspaces/$node_id`)
+- Each node routes all `mo_runtime_exec` calls through its workspace
+- With bubblewrap: each exec is isolated (fresh tmpfs, read-only system paths, only the node's workspace is writable)
+- With docker: each node session gets its own container (keyed by `node_id`)
+
+No changes to the parallel dispatch logic itself — just routing each node's exec calls through the runtime interface with the correct workspace.
+
+---
+
+## 10. Key Differences Between the Two References
+
+| Concern | mini-swe-agent | swe-rex |
+|---|---|---|
+| Exec model | Stateless `execute(action, cwd)` per call | Both stateless `execute(Command)` AND stateful `run_in_session(Action)` |
+| Filesystem persistence across calls | No (each exec is a new process) | Yes via sessions (pexpect bash stays alive between calls) |
+| Remote execution | Via SwerexDockerEnvironment adapter → HTTP | Native via RemoteRuntime → HTTP server inside sandbox |
+| Backend selection | String key `environment_class` in YAML config | Discriminated union Pydantic config, `get_deployment()` factory |
+| Parallelism unit | ThreadPoolExecutor worker = one container = one agent | Caller responsibility; each Deployment instance is independent |
+| Bubblewrap | Full implementation, no-root, per-exec | Not implemented (swe-rex focuses on docker/modal/fargate) |
+| File transfer | Not needed (single-machine assumption) | Native: `upload`, `read_file`, `write_file` in AbstractRuntime |
+| Cloud execution | Via swerex_modal adapter (bridges to swe-rex) | Native: ModalDeployment, FargateDeployment |
+
+---
+
+## 11. Implementation Checklist
+
+### R0 — Stateless exec hook (1–2 days, zero new deps)
+- [ ] Create `lib/runtime.sh` (backend router)
+- [ ] Create `lib/runtime/local.sh` (no-op wrapper, same behavior as today)
+- [ ] Source `lib/runtime.sh` in `bin/mini-ork-execute` startup block
+- [ ] Replace `_run_verifier_ref`'s `( cd ... && bash ... )` with `mo_runtime_exec`
+- [ ] Replace naked `cd + bash` patterns in `lib/llm-dispatch.sh` with `mo_runtime_exec`
+- [ ] Add process-group kill on timeout (steal mini-swe-agent's `setsid`/`kill -- -$pgid`)
+
+### R1 — Runtime interface contract (1 day)
+- [ ] Document the 6-function contract in `lib/runtime/README.md`
+- [ ] Add a contract smoke test (source backend + call each function with a noop cmd)
+
+### R2a — Bubblewrap backend (2–3 days, Linux-only, no root)
+- [ ] Create `lib/runtime/bubblewrap.sh`
+- [ ] Wire node workspace dir (per-node `$RUN_DIR/workspaces/$node_id`) as the bind-mount target
+- [ ] Add `MO_RUNTIME_BACKEND=bubblewrap` to `.env.example` and CI
+- [ ] Test: verifier cannot write outside its workspace; parallel nodes cannot interfere
+
+### R2b — Docker backend (3–4 days)
+- [ ] Create `lib/runtime/docker.sh`
+- [ ] Wire `mo_runtime_session_create/close` to `docker run -d` / `docker stop` lifecycle
+- [ ] Wire `mo_runtime_put/get` to `docker cp`
+- [ ] Test: parallel implementer nodes each get an isolated container
+
+### R2c — swerex bridge for cloud (Phase 2, ~1 week)
+- [ ] Create `lib/runtime/swerex_bridge.sh` + `lib/runtime/swerex_exec.py`
+- [ ] Support `MO_SWEREX_DEPLOYMENT_TYPE=modal` for serverless cloud runs
+- [ ] Test: implementer writes files inside Modal sandbox, retrieve them via `mo_runtime_get`
+- [ ] Document `MO_SWEREX_*` env vars in runbook
+
+### Phase 2 — Implementer isolation (requires prompt-level changes)
+- [ ] Pass workspace path into implementer prompt so Claude writes to sandbox, not host checkout
+- [ ] After implementer finishes, `mo_runtime_get` the workspace back and apply as a patch to target repo
+- [ ] This fully closes the cross-repo corruption vector

+# Impl analysis 02 — Managed cloud sandbox + controller/runtime split
+## Source-code analysis of E2B SDK and OpenHands runtime/controller
+
+**Gap targeted:** mini-ork has no managed/remote execution and no controller↔runtime split.
+The orchestrator and every worker share one host filesystem.
+To run agents safely in the cloud you need (a) a sandbox the orchestrator does NOT share
+a disk with, and (b) a transport layer so the same recipe drives local or remote execution
+without changing node logic.
+
+Doc 01 (swe-rex / mini-swe-agent) covered the *interface contract* between controller and
+runtime. This document covers the *managed/cloud realization* — how E2B builds an HTTP-API
+microVM sandbox, and how OpenHands wires controller and runtime together through an
+EventStream so they never import each other.
+
+**Sources read:**
+- `/private/tmp/miniork-ref-analysis/code-interpreter/` — E2B `e2b-dev/code-interpreter` SDK
+- `/private/tmp/miniork-ref-analysis/OpenHands/` — current main (restructured);
+  runtime/controller detail fetched from GitHub tag `0.21.0` (SHA `a4ee454`)
+- `/Users/admin/.local/share/uv/tools/omnigent/lib/python3.12/site-packages/agents/extensions/sandbox/e2b/sandbox.py`
+  — full E2B base SDK surface including files, commands, PTY, lifecycle, snapshot
+- mini-ork: `bin/mini-ork-execute` (partial), `lib/sandbox/*.sh`, `lib/llm-dispatch.sh`
+
+---
+
+## 1. E2B SDK shape — Firecracker microVM as an HTTP API
+
+### 1.1 What E2B actually is
+
+Each E2B sandbox is a **Firecracker microVM** (own kernel, own memory, no shared FS with
+the host). The SDK is a thin HTTPS client. Nothing runs locally except curl / Python HTTP.
+
+Key constants (`e2b_code_interpreter/constants.py`):
+
+```python
+DEFAULT_TEMPLATE = "code-interpreter-v1"
+JUPYTER_PORT     = 49999
+DEFAULT_TIMEOUT  = 300          # seconds
+```
+
+### 1.2 `class Sandbox(BaseSandbox)` — the code-interpreter overlay
+
+**File:** `python/e2b_code_interpreter/code_interpreter_sync.py:34`
+
+```python
+class Sandbox(BaseSandbox):                       # BaseSandbox = e2b.Sandbox
+    default_template = DEFAULT_TEMPLATE
+
+    @property
+    def _jupyter_url(self) -> str:
+        return f"https://{self.get_host(JUPYTER_PORT)}"
+
+    @property
+    def _client(self) -> Client:
+        # Forces HTTP/1.1 — HTTP/2 multiplexing hides TCP disconnect from the Jupyter server
+        return Client(transport=get_transport(self.connection_config, http2=False))
+```
+
+**Critical detail on HTTP/1.1:** The comment in the source is explicit — with HTTP/2
+a client disconnect only cancels the HTTP/2 stream; the underlying TCP connection stays
+open, so the Jupyter server never learns that the caller disconnected and keeps running
+the code. Forcing HTTP/1.1 restores the 1:1 TCP-request mapping so a disconnect
+propagates to the server as a TCP close. This is a subtle correctness constraint any
+mini-ork E2B adapter must replicate when streaming output.
+
+### 1.3 `run_code` — streaming NDJSON execution
+
+```python
+def run_code(
+    self,
+    code: str,
+    language: Optional[str] = None,
+    context: Optional[Context] = None,
+    on_stdout: Optional[OutputHandler[OutputMessage]] = None,
+    on_stderr: Optional[OutputHandler[OutputMessage]] = None,
+    on_result: Optional[OutputHandler[Result]] = None,
+    on_error: Optional[OutputHandler[ExecutionError]] = None,
+    envs: Optional[Dict[str, str]] = None,
+    timeout: Optional[float] = None,
+    request_timeout: Optional[float] = None,
+) -> Execution:
+    with self._client.stream(
+        "POST",
+        f"{self._jupyter_url}/execute",
+        json={"code": code, "context_id": context_id,
+              "language": language, "env_vars": envs},
+        headers=headers,
+        timeout=(request_timeout, timeout, request_timeout, request_timeout),
+    ) as response:
+        for line in response.iter_lines():
+            parse_output(execution, line, on_stdout=..., on_stderr=...,
+                         on_result=..., on_error=...)
+        return execution
+```
+
+**NDJSON protocol** (`models.py:_parse_output`):
+
+| `type` field           | Model class      | Purpose                              |
+|------------------------|------------------|--------------------------------------|
+| `stdout`               | `OutputMessage`  | line + timestamp + error=False       |
+| `stderr`               | `OutputMessage`  | line + timestamp + error=True        |
+| `result`               | `Result`         | MIME-typed: text/html/png/svg/json/chart |
+| `error`                | `ExecutionError` | name + value + traceback             |
+| `number_of_executions` | `int`            | kernel execution counter             |
+
+### 1.4 Context (persistent kernel) API
+
+Analogous to a stateful Jupyter kernel — variables from one `run_code` call survive
+into the next if they share the same context.
+
+```python
+sandbox.create_code_context(cwd="/home/user", language="python") -> Context
+sandbox.list_code_contexts()  -> List[Context]
+sandbox.remove_code_context(context)
+sandbox.restart_code_context(context)
+```
+
+`Context` dataclass: `id: str`, `language: str`, `cwd: str`
+
+### 1.5 Base SDK — files, commands, PTY, lifecycle
+
+Sourced from omnigent's bundled E2B integration (covers the full base SDK surface, not
+just the code-interpreter overlay):
+
+#### Files API
+```python
+sandbox.files.read(path, format="bytes")   -> bytes | str
+sandbox.files.write(path, data: bytes)     -> None
+sandbox.files.make_dir(path)               -> None
+sandbox.files.remove(path)                 -> None
+```
+
+#### Commands API
+```python
+sandbox.commands.run(
+    cmd_str,
+    timeout=None,       # seconds
+    cwd="/",
+    envs={},
+    user="user",
+    on_stdout=None,
+    on_stderr=None,
+    background=False,
+) -> ExecResult(stdout, stderr, exit_code)
+```
+
+#### Lifecycle API
+```python
+Sandbox.create(
+    template="code-interpreter-v1",
+    timeout=3600,                    # seconds until auto-kill
+    metadata={},
+    envs={},
+    on_timeout="kill"|"pause",       # what happens at timeout
+    auto_resume=True,                # reconnect to existing sandbox on create
+) -> Sandbox
+
+Sandbox.connect(sandbox_id, timeout=...) -> Sandbox   # re-attach to running sandbox
+
+sandbox.pause()                          # persist state, release compute
+sandbox.kill()                           # hard delete
+sandbox.is_running()    -> bool
+sandbox.get_host(port)  -> str           # exposed hostname for port

+
+Key insight: **the orchestrator never touches the sandbox filesystem directly**. All

+
+## 2. OpenHands — Runtime abstraction and controller/runtime split
+
+### 2.1 The base `Runtime` class
+
+**File:** `openhands/runtime/base.py` (tag 0.21.0)
+
+```python
+class Runtime(FileEditRuntimeMixin):
+    def __init__(
+        self,
+        config: AppConfig,
+        event_stream: EventStream,
+        sid: str,
+        plugins: list[PluginRequirement],
+        env_vars: dict[str, str],
+        status_callback: Callable,
+        attach_to_existing: bool,
+        headless_mode: bool,
+    ):
+        # Only coupling to controller: a shared EventStream
+        event_stream.subscribe(
+            EventStreamSubscriber.RUNTIME,
+            self.on_event,
+            self.sid,
+        )
+```
+
+**`on_event` → `_handle_action` → `run_action`:**
+
+```python
+def on_event(self, event: Event) -> None:
+    if isinstance(event, Action):
+        asyncio.get_event_loop().run_until_complete(self._handle_action(event))
+
+async def _handle_action(self, event: Action) -> None:
+    observation = await self.run_action(event)
+    observation._cause = event.id          # causal link back to the action
+    self.event_stream.add_event(observation, EventSource.ENVIRONMENT)
+
+async def run_action(self, action: Action) -> Observation:
+    action_type = action.action            # e.g. "run", "read", "write"
+    observation = await getattr(self, action_type)(action)  # method name dispatch
+    return observation
+```
+
+**`action.action` IS the method name.** This is the key dispatch mechanism — no switch
+statement, no routing table. The action type string maps directly to a Runtime method.
+
+### 2.2 Abstract methods — the full Runtime interface
+
+```python
+@abstractmethod async def connect(self) -> None
+@abstractmethod async def run(self, action: CmdRunAction) -> CmdOutputObservation
+@abstractmethod async def run_ipython(self, action: IPythonRunCellAction) -> IPythonRunCellObservation
+@abstractmethod async def read(self, action: FileReadAction) -> FileReadObservation
+@abstractmethod async def write(self, action: FileWriteAction) -> FileWriteObservation
+@abstractmethod async def browse(self, action: BrowseURLAction) -> BrowserOutputObservation
+@abstractmethod async def browse_interactive(self, action: BrowseInteractiveAction) -> BrowserOutputObservation
+@abstractmethod async def copy_to(self, host_src: str, sandbox_dest: str, recursive: bool) -> None
+@abstractmethod async def list_files(self, path: str) -> list[str]
+@abstractmethod async def copy_from(self, path: str) -> Path
+```
+
+### 2.3 Six interchangeable runtime implementations
+
+**Directory:** `openhands/runtime/impl/`
+
+| Implementation   | Where execution happens          | How it connects                    |
+|------------------|----------------------------------|------------------------------------|
+| `DockerRuntime`  | Docker container on local host   | docker exec                        |
+| `E2BRuntime`     | E2B Firecracker microVM cloud    | E2B SDK (HTTP)                     |
+| `ModalRuntime`   | Modal cloud functions            | Modal SDK                          |
+| `RemoteRuntime`  | Remote machine / Runloop cloud   | HTTP to agent server inside box    |
+| `ProcessRuntime` | Subprocess on local host         | subprocess + tmpdir                |
+| `action_execution/` | In-process action server      | Used inside the sandbox itself     |
+
+**Zero changes to AgentController when swapping runtimes** — the controller only knows
+about `EventStream`. The runtime implementation is completely transparent to the agent.
+
+### 2.4 `E2BBox` — the E2B runtime adapter
+
+**File:** `openhands/runtime/impl/e2b/sandbox.py`
+
+```python
+class E2BBox:
+    def __init__(self, e2b_api_key: str, template: str):
+        self.sandbox = E2BSandbox(
+            api_key=e2b_api_key,
+            template=template,
+            on_stderr=lambda msg: ...,
+            on_stdout=lambda msg: ...,
+            cwd=self._cwd,
+        )
+
+    def execute(self, cmd: str, timeout: int) -> tuple[int, str]:
+        process = self.sandbox.process.start(cmd, env_vars=self._env)
+        process.wait(timeout=timeout)
+        return process.exit_code, "\n".join(messages)
+
+    def copy_to(self, host_src: str, sandbox_dest: str, recursive: bool):
+        # tar on host -> upload -> untar inside sandbox
+        self.sandbox.upload_file(tar_file)
+        self.sandbox.process.start_and_wait(
+            f"sudo tar -xf {uploaded_path} -C {sandbox_dest} ..."
+        )
+
+    @property
+    def filesystem(self):
+        return self.sandbox.filesystem
+
+    def close(self):
+        self.sandbox.close()
+```
+
+The pattern: wrap the E2B SDK in a thin class that implements the Runtime's `execute` /
+`copy_to` / `filesystem` contract. The Runtime's abstract methods delegate to this box.
+
+---
+
+## 3. Action → Observation model and why it enables remote execution
+
+### 3.1 `CmdRunAction` — the action side
+
+```python
+@dataclass
+class CmdRunAction(Action):
+    command: str
+    timeout: Optional[float] = None
+    thought: str = ""
+    action: str = "run"          # THIS IS THE DISPATCH KEY
+    id: str = field(default_factory=lambda: str(uuid4()))
+```
+
+### 3.2 `CmdOutputObservation` — the observation side
+
+```python
+@dataclass
+class CmdOutputObservation(Observation):
+    command: str
+    exit_code: int
+    content: str                 # stdout + stderr
+    _cause: str = ""             # set to action.id by Runtime._handle_action
+```
+
+### 3.3 Causal linking
+
+```python
+# In Runtime._handle_action:
+observation._cause = event.id    # ties observation back to its trigger action
+```
+
+AgentController checks `obs.cause == self._pending_action.id` to know which action
+the observation answers. This is how asynchronous, out-of-order observations are
+matched back to the controller's state machine.
+
+### 3.4 Sequence diagram — decoupled execution
+
+```mermaid
+sequenceDiagram
+    participant Agent
+    participant EventStream
+    participant Runtime
+
+    Agent->>EventStream: publish(CmdRunAction{action="run", id="a1"})
+    EventStream->>Runtime: on_event(CmdRunAction)
+    Runtime->>Runtime: getattr(self, "run")(action)
+    Note over Runtime: executes in sandbox (local or cloud)
+    Runtime->>EventStream: publish(CmdOutputObservation{_cause="a1"})
+    EventStream->>Agent: on_event(CmdOutputObservation)
+    Agent->>Agent: _pending_action.id == obs.cause then clear then step()
+```
+
+### 3.5 Why this enables remote execution
+
+The EventStream is the **only coupling** between AgentController and Runtime.
+Neither imports the other. The only shared artifact is the event schema.
+
+This means:
+- `DockerRuntime` can run on the local machine, `E2BRuntime` on E2B cloud,
+  `RemoteRuntime` on a different machine — the Agent never knows.
+- The transport (subprocess pipe, docker exec, HTTPS to E2B) is encapsulated inside
+  the Runtime implementation behind the same abstract interface.
+- Mini-ork can adopt this pattern entirely in bash — a JSON file or named pipe IS
+  the EventStream.
+
+### 3.6 AgentController pending-action pattern
+
+**File:** `openhands/controller/agent_controller.py` (tag 0.21.0, ~43K)
+
+```python
+class AgentController:
+    def __init__(self, agent, event_stream, ...):
+        event_stream.subscribe(
+            EventStreamSubscriber.AGENT_CONTROLLER,
+            self.on_event,
+            self.id,
+        )
+        self._pending_action: Optional[Action] = None
+
+    async def _step(self):
+        action = await self.agent.step(self.state)
+        self._pending_action = action
+        self.event_stream.add_event(action, EventSource.AGENT)
+
+    def _handle_observation(self, obs: Observation):
+        if (self._pending_action
+                and obs.cause == self._pending_action.id):
+            self._pending_action = None      # clear -> ready for next step
+            # trigger state transitions / next step()
+```
+
+**Delegate pattern:** `start_delegate(AgentDelegateAction)` spawns a nested
+`AgentController(is_delegate=True)` sharing the same EventStream. Observations
+from the delegate bubble up to the parent. This is OpenHands' sub-agent mechanism.
+
+---
+
+## 4. Adoption plan for mini-ork
+
+mini-ork today has the right skeleton but hollow implementations:
+
+| What mini-ork has                | Gap                                          |
+|----------------------------------|----------------------------------------------|
+| `lib/sandbox/daytona.sh`         | Falls back to local; no real API calls       |
+| `lib/sandbox/local.sh`           | Works but shares host FS                     |
+| `lib/sandbox/modal.sh`           | Falls back to local                          |
+| `lib/sandbox/omnigent-bridge.sh` | Partial bridge, not a full runtime           |
+| No `lib/sandbox/e2b.sh`          | Missing                                      |
+| No runtime-dispatch router       | Missing                                      |
+| No NodeAction/NodeObservation    | Missing (nodes push text, not typed events)  |
+| No workspace archive/restore     | Missing                                      |
+
+### 4.1 New file: `lib/sandbox/e2b.sh`
+
+Thin bash shim — each function calls a one-liner Python that uses the E2B SDK.
+The Python shim avoids re-implementing the E2B REST protocol in bash.
+
+```bash
+#!/usr/bin/env bash

+sys.exit(r.exit_code)
+PYEOF
+}
+
+mo_sandbox_e2b_put() {

+    local sid="$1" action="${2:-pause}"
+    python3 - <<PYEOF
+import e2b
+s = e2b.Sandbox.connect("$sid")
+getattr(s, "$action")()
+PYEOF
+}
+```
+
+### 4.2 New file: `lib/sandbox/runtime-dispatch.sh`
+
+The `SandboxService`-equivalent router. Selects backend by `MO_SANDBOX_BACKEND`.
+
+```bash
+#!/usr/bin/env bash
+# lib/sandbox/runtime-dispatch.sh -- backend selector, analogous to OpenHands SandboxService ABC
+
+_MO_SANDBOX_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+source "$_MO_SANDBOX_DIR/local.sh"
+source "$_MO_SANDBOX_DIR/e2b.sh"
+source "$_MO_SANDBOX_DIR/daytona.sh"
+source "$_MO_SANDBOX_DIR/modal.sh"
+
+_mo_sandbox_backend() { echo "${MO_SANDBOX_BACKEND:-local}"; }
+
+mo_sandbox_provision()  { "mo_sandbox_$(_mo_sandbox_backend)_provision" "$@"; }
+mo_sandbox_exec()       { "mo_sandbox_$(_mo_sandbox_backend)_exec" "$@"; }
+mo_sandbox_put()        { "mo_sandbox_$(_mo_sandbox_backend)_put" "$@"; }
+mo_sandbox_get()        { "mo_sandbox_$(_mo_sandbox_backend)_get" "$@"; }
+mo_sandbox_cleanup()    { "mo_sandbox_$(_mo_sandbox_backend)_cleanup" "$@"; }
+```
+
+### 4.3 NodeAction / NodeObservation JSON (the EventStream equivalent)
+
+mini-ork's equivalent of OpenHands' EventStream is a JSON protocol written to/from
+files (or piped between processes). This is the controller-to-runtime seam.
+
+**NodeAction schema** (written by `bin/mini-ork-execute` before dispatching a node):
+
+```json
+{
+  "action":       "run_node",
+  "action_id":    "act-implementer_1-001",
+  "node_id":      "implementer_1",
+  "node_type":    "implementer",
+  "model_lane":   "codex",
+  "prompt_ref":   "path/to/node.md",
+  "kickoff_path": "path/to/kickoff.md",
+  "timeout_s":    1500,
+  "sandbox_ref":  "sbx-abc123",
+  "env":          {}
+}
+```
+
+**NodeObservation schema** (written by the runtime / node-executor back to controller):
+
+```json
+{
+  "cause":         "act-implementer_1-001",
+  "node_id":       "implementer_1",
+  "node_type":     "implementer",
+  "status":        "success",
+  "exit_code":     0,
+  "verdict":       "approve",
+  "files_written": ["src/foo.py"],
+  "cost_usd":      0.14,
+  "duration_ms":   42000,
+  "artifact_path": "runs/run-001/implementer_1/output.md"
+}
+```
+
+The `cause` field mirrors OpenHands' `observation._cause = action.id`.
+`bin/mini-ork-execute` reads the observation, matches `cause` to the dispatched action,
+and decides whether to continue, retry, or halt — exactly as
+`AgentController._handle_observation`.
+
+### 4.4 New file: `lib/node-executor.sh` — the Runtime inside the sandbox
+
+Wraps a node's LLM dispatch behind the NodeObservation protocol. Runs inside the sandbox
+(when using E2B/Daytona) or on the host (when using local).
+
+```bash
+#!/usr/bin/env bash
+# lib/node-executor.sh -- runs one node, emits NodeObservation JSON
+# Equivalent to OpenHands Runtime.run_action() for a single node type
+
+_MO_LIB_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+source "$_MO_LIB_DIR/llm-dispatch.sh"
+
+mo_node_execute() {
+    local action_json="$1"       # path to NodeAction JSON file
+    local obs_path="$2"          # where to write NodeObservation JSON
+
+    local node_id node_type model_lane prompt_ref timeout_s cause
+    node_id=$(jq -r '.node_id'     "$action_json")
+    node_type=$(jq -r '.node_type' "$action_json")
+    model_lane=$(jq -r '.model_lane' "$action_json")
+    prompt_ref=$(jq -r '.prompt_ref' "$action_json")
+    timeout_s=$(jq -r '.timeout_s // 1500' "$action_json")
+    cause=$(jq -r '.action_id // "unknown"' "$action_json")
+
+    local start_ms output_file exit_code
+    start_ms=$(date +%s%3N)
+    output_file="$(mktemp)"
+
+    mo_llm_dispatch "$model_lane" "$(cat "$prompt_ref")" "$output_file" "$timeout_s" \
+        && exit_code=0 || exit_code=$?
+
+    local end_ms duration_ms verdict
+    end_ms=$(date +%s%3N)
+    duration_ms=$(( end_ms - start_ms ))
+    verdict="$([ $exit_code -eq 0 ] && echo approve || echo reject)"
+
+    jq -n \
+        --arg cause        "$cause" \
+        --arg node_id      "$node_id" \
+        --arg node_type    "$node_type" \
+        --arg status       "$([ $exit_code -eq 0 ] && echo success || echo error)" \
+        --argjson exit_code "$exit_code" \
+        --arg verdict      "$verdict" \
+        --argjson duration_ms "$duration_ms" \
+        --arg artifact_path "$output_file" \
+    '{cause:$cause, node_id:$node_id, node_type:$node_type,
+      status:$status, exit_code:$exit_code, verdict:$verdict,
+      duration_ms:$duration_ms, artifact_path:$artifact_path}' \
+        > "$obs_path"
+}
+```
+
+### 4.5 `bin/mini-ork-execute` changes — the Controller side
+
+The controller changes are minimal — add sandbox lifecycle calls around the existing
+node dispatch loop, and read NodeObservation JSON instead of relying on implicit exit codes.
+
+```bash
+# run start
+sandbox_id=$(mo_sandbox_provision)
+mo_sandbox_put "$sandbox_id" "$WORKTREE_PATH" "/workspace"
+
+# per node dispatch (replaces current direct node invocation)
+write_node_action_json "$node_id" "$node_type" "$model_lane" "$prompt_ref" \
+    "$sandbox_id" > "$action_path"
+mo_sandbox_exec "$sandbox_id" \
+    "source lib/node-executor.sh && mo_node_execute $action_path $obs_path"
+obs=$(cat "$obs_path")
+verdict=$(echo "$obs" | jq -r '.verdict')
+# existing retry / stop-control logic uses verdict
+
+# run end
+mo_sandbox_get "$sandbox_id" "/workspace" "$LOCAL_ARTIFACT_PATH"
+mo_sandbox_cleanup "$sandbox_id"   # default: pause for cost control
+```
+

+
+```
+Phase 0 (now):
+  lib/sandbox/runtime-dispatch.sh + wire local.sh through it.
+  No behavior change; adds the routing layer with zero risk.
+
+Phase 1:
+  lib/sandbox/e2b.sh (5 functions).
+  lib/node-executor.sh (NodeObservation emitter).
+  Smoke test: MO_SANDBOX_BACKEND=e2b on one implementer node.
+
+Phase 2:
+  bin/mini-ork-execute sandbox lifecycle (provision / put / get / cleanup).
+  NodeAction JSON written before dispatch, NodeObservation read after.
+
+Phase 3:
+  Workspace archiving: tar worktree in, tar diff/artifacts out.
+  Cost control: mo_sandbox_cleanup with pause-not-kill.
+  Daytona backend: real API calls replacing local fallback.
+```
+

+
+## 5. Key lessons from the reference implementations
+
+### L1 — Agent server inside the sandbox, not outside
+
+Both E2B and OpenHands (current main: `openhands/app_server/sandbox/`) converge on
+putting the execution server *inside* the isolated environment, exposed over HTTP. The
+orchestrator is just an HTTP client. Mini-ork's equivalent: `node-executor.sh` running
+inside the microVM.
+
+### L2 — One abstract interface, multiple transports
+
+OpenHands' `Runtime` ABC has 10 abstract methods. `E2BRuntime`, `DockerRuntime`, and
+`ProcessRuntime` all implement the same interface. The controller imports neither.
+Mini-ork's equivalent: `mo_sandbox_exec / put / get / cleanup` — same 5 names regardless
+of backend.
+
+### L3 — HTTP/1.1 for streaming
+
+E2B forces HTTP/1.1 for Jupyter execution streams because HTTP/2 multiplexing hides
+TCP disconnects from the server (`code_interpreter_sync.py:64-79`). Any mini-ork adapter
+that streams output from a remote process should use `curl --http1.1` (or an explicit
+flag) to ensure disconnects propagate.
+
+### L4 — Causal linking (`_cause`) makes async observable
+
+`observation._cause = action.id` is what lets the controller match async responses to
+their triggering actions without polling. Mini-ork's `NodeObservation.cause` field is
+the bash equivalent. Without it, a verifier observation is ambiguous if multiple nodes
+run concurrently.
+
+### L5 — Pause > Kill for cost
+
+E2B `on_timeout="pause"` + `auto_resume=True` means sandboxes survive restart and
+can be pooled. Paying for cold-boot time on every run wastes budget. Mini-ork should
+default `MO_SANDBOX_E2B_ON_TIMEOUT=pause` and reuse sandbox IDs within a run.
+
+### L6 — Workspace transfer, not shared mount
+
+The current mini-ork worktree is on the host FS, so all agents share it implicitly.
+E2B/OpenHands both require explicit workspace transfer (`files.write` / `copy_to` /
+`archive_conversation_workspace`). This is the biggest structural change needed in
+mini-ork and the step that makes runs truly isolated.
+

+
+## 1. GEPA Algorithm — Step-by-Step with Code Anchors
+
+GEPA (Genetic-Pareto) is a black-box optimizer for **textual parameters** (prompts,
+code, agent architectures). Its key insight: instead of collapsing execution traces
+into a single scalar and backpropagating through it (GRPO), GEPA feeds the **full
+execution trace** to an LLM "reflection" model, which reads the trace and proposes
+targeted rewrites of the textual parameters. This replaces 5,000–25,000 GRPO rollouts
+with 100–500 GEPA evaluations.
+
+### 1.1 Entrypoint / Optimizer Class
+
+**File:** `src/gepa/core/engine.py`
+**Class:** `GEPAEngine` (line 51)
+
+```python
+class GEPAEngine(Generic[DataId, DataInst, Trajectory, RolloutOutput]):
+    """Orchestrates the optimization loop using pluggable candidate proposers."""
+```
+
+`GEPAEngine.run()` (line 458) is the main loop. The loop is bounded by a
+`StopperProtocol` callback (typically `MaxMetricCallsStopper` at 100–500 calls).
+
+### 1.2 The GEPA Loop — Six Phases Per Iteration
+
+Each iteration of `GEPAEngine.run()` executes the following, delegated to
+`ReflectiveMutationProposer` (`src/gepa/proposer/reflective_mutation/reflective_mutation.py`):
+
+```
+Phase 1 — Pareto-select parent candidate
+Phase 2 — Sample minibatch from trainset
+Phase 3 — Evaluate parent with full trace capture  (capture_traces=True)
+Phase 4 — Build reflective dataset from traces
+Phase 5 — LLM proposes mutated candidate text
+Phase 6 — Evaluate mutation on same minibatch; accept/reject; full-valset eval if accepted
+```
+
+#### Phase 1 — Pareto-select parent (`candidate_selector.py`)
+
+```python
+# src/gepa/strategies/candidate_selector.py, class ParetoCandidateSelector
+def select_candidate_idx(self, state: GEPAState) -> int:
+    return select_program_candidate_from_pareto_front(
+        state.get_pareto_front_mapping(),
+        state.per_program_tracked_scores,
+        self.rng,
+    )
+```
+
+`select_program_candidate_from_pareto_front` (`gepa_utils.py`, line 90) first prunes
+dominated candidates (`remove_dominated_programs`), then samples proportional to how
+many validation examples each Pareto-front member "wins" on. This selects candidates
+that are good on *different* subsets — avoiding premature convergence to a single
+optimum. The Pareto front is over **per-example** validation scores (frontier_type =
+"instance"): candidate A is non-dominated if there exists at least one validation
+example where it is best.
+
+#### Phase 2 — Minibatch sample
+
+`batch_sampler.next_minibatch_ids()` draws a small subsample (default ~10–20
+examples) from the training set. Full valset evaluation only happens when a candidate
+passes the acceptance gate.
+
+#### Phase 3 — Evaluate with trace capture
+
+```python
+# reflective_mutation.py, line 268
+eval_curr = self.adapter.evaluate(ctx.minibatch, ctx.curr_prog, capture_traces=True)
+```
+
+The adapter returns an `EvaluationBatch` including:
+
+- `outputs`: raw per-example outputs (opaque to GEPA)
+- `scores`: per-example floats (higher is better)
+- `trajectories`: per-example trace objects (only when `capture_traces=True`)
+
+#### Phase 4 — Build reflective dataset
+
+```python
+# reflective_mutation.py, line 341
+reflective_dataset = self.adapter.make_reflective_dataset(
+    ctx.curr_prog, eval_curr, predictor_names_to_update
+)
+```
+
+The adapter converts trajectories + scores + outputs into a structured
+`Mapping[component_name, list[dict]]` — one record per example, with fields like:
+
+```json
+{
+  "Inputs":            { "question": "...", "context": "..." },
+  "Generated Outputs": "...",
+  "Feedback":          "Wrong answer. Expected 42, got 7. ..."
+}
+```
+
+This is the **textual gradient** — the LLM-readable signal about what went wrong.
+
+#### Phase 5 — Propose mutated candidate text
+
+```python
+# reflective_mutation.py, line 369
+new_texts, prompts, raw_lm_outputs = self.propose_new_texts(
+    ctx.curr_prog, reflective_dataset, predictor_names_to_update
+)
+```
+
+`propose_new_texts` calls `InstructionProposalSignature.run_with_metadata()`
+(`src/gepa/strategies/instruction_proposal.py`, line 13) with this default prompt
+template:
+
+```
+I provided an assistant with the following instructions to perform a task for me:
+```<curr_param>```
+
+The following are examples of different task inputs provided to the assistant
+along with the assistant's response for each of them, and some feedback on how
+the assistant's response could be better:
+```<side_info>```
+
+Your task is to write a new instruction for the assistant.
+... (reflect on niche strategies, include domain-specific facts)
+Provide the new instructions within ``` blocks.
+```
+
+The reflection LM reads the current prompt text, the failures with
+per-example feedback, and produces a revised instruction. This is the core
+"textual gradient descent" — the LM reasons about *why* specific examples
+failed and edits the instruction to prevent those failures.
+
+#### Phase 6 — Minibatch-gate then full-valset eval
+
+```python
+# reflective_mutation.py, line 420
+eval_after = self.adapter.evaluate(ctx.minibatch, new_candidate, capture_traces=True)
+```
+
+The same minibatch is re-evaluated with the mutated candidate. Acceptance test
+(`StrictImprovementAcceptance`, `acceptance.py`, line 39):
+
+```python
+def should_accept(self, proposal, state) -> bool:
+    old_sum = sum(proposal.subsample_scores_before or [])
+    new_sum  = sum(proposal.subsample_scores_after  or [])
+    return new_sum > old_sum
+```
+
+If accepted, the candidate is evaluated on the **full valset** and added to the
+Pareto front. If rejected, no full-valset rollout occurs — the minibatch guard is
+the primary cost-savings mechanism.
+
+### 1.3 Textual Feedback vs Scalar Reward
+
+| Dimension | GRPO | GEPA |
+|---|---|---|
+| Signal type | Scalar reward per rollout | Full trace + per-example text feedback |
+| How improvement is proposed | Policy gradient update on weights | LLM reads failures, edits prompt text |
+| What is "learned" | Weight tensors | Prompt/instruction text |
+| Rollouts to converge | 5,000–25,000 | 100–500 |
+| What "gradient" means | Numerical gradient ∂L/∂θ | `make_reflective_dataset` → LLM diff |
+
+GEPA uses the scalar reward only as a **filter** (minibatch acceptance gate).
+The actual mutation is driven by the LLM reading the full trajectory — error
+messages, reasoning logs, wrong outputs — and producing a targeted rewrite.
+
+---
+
+## 2. The Adapter Interface — What mini-ork Would Implement
+
+**File:** `src/gepa/core/adapter.py`
+**Protocol:** `GEPAAdapter[DataInst, Trajectory, RolloutOutput]` (line 59)
+
+A GEPA adapter implements two required methods and one optional:
+
+### 2.1 `evaluate(batch, candidate, capture_traces) -> EvaluationBatch`
+
+Runs the system with the given `candidate` (a `dict[str, str]` mapping component
+name to text, e.g. `{"system_prompt": "..."}`) on a batch of inputs, and returns
+per-example scores and (when `capture_traces=True`) trace objects.
+
+For mini-ork: a "candidate" would be a recipe's textual parameters, a "batch
+instance" would be a task spec, and a "score" would be derived from `process_reward`
+or an outcome metric. "Trajectories" would be execution trace rows from
+`execution_traces`.
+
+### 2.2 `make_reflective_dataset(candidate, eval_batch, components_to_update) -> Mapping[str, list[dict]]`
+
+Converts trace objects and scores into per-component feedback records for the
+reflection LLM. Each record should include inputs, outputs, and natural-language
+feedback about what went wrong and what the correct answer would have been.
+
+For mini-ork: this would serialize execution trace fields (node outputs, tool calls,
+reviewer verdicts, error messages) into structured feedback dicts keyed by
+recipe component (e.g. `"planner_prompt"`, `"synthesizer_prompt"`).
+
+### 2.3 Optional `propose_new_texts(candidate, reflective_dataset, components) -> dict[str, str]`
+
+If implemented, bypasses GEPA's default `InstructionProposalSignature` prompt and
+calls whatever LLM/logic the user prefers. mini-ork could use its existing
+`llm-dispatch.sh` here.
+
+---
+
+## 3. Why GEPA Needs Far Fewer Rollouts Than GRPO
+
+Three concrete mechanisms explain the 35x rollout reduction:
+
+### 3.1 Minibatch-gated acceptance (the primary savings mechanism)
+
+GRPO evaluates each rollout on the full dataset to compute group statistics and
+update the policy. GEPA evaluates each *candidate mutation* on a tiny subsample
+(~10–20 examples). Only mutations that improve on the subsample proceed to full
+valset evaluation. Because most random mutations are rejected, the vast majority
+of expensive full-valset runs are avoided.
+
+```
+GRPO:  N_rollouts × full_dataset evaluations
+GEPA:  N_mutations × subsample evaluations  +  N_accepted × full_valset evaluations
+         (N_accepted << N_mutations)
+```
+
+### 3.2 Pareto-front candidate selection avoids wasted exploration
+
+GRPO explores by sampling from a policy distribution — many samples cluster near
+already-discovered optima. GEPA selects candidates proportional to how many
+validation examples they "win" on (Pareto domination). This naturally focuses
+exploration on under-optimized examples, not re-exploring already-solved ones.
+
+### 3.3 LLM mutation targets failures directly
+
+GRPO produces a gradient signal that is diffuse — it nudges policy weights toward
+better-rewarded trajectories without explaining *why* specific examples failed.
+GEPA's reflection step has the LLM read error messages and wrong outputs, then
+make targeted edits to the instruction. This means fewer "random walks" before
+finding an improvement: each proposal is causally informed by failure reasons.
+
+The `InstructionProposalSignature.default_prompt_template` explicitly asks the
+reflection LM to "Identify all niche and domain-specific factual information" from
+the feedback and include it in the new instruction — a targeted, theory-of-change
+edit rather than a gradient step.
+
+---
+
+## 4. Adoption Plan for mini-ork (GEPA Alongside Existing GRPO)
+
+### 4.1 What GEPA Would Optimize in mini-ork
+
+In GEPA's vocabulary, the "textual parameters" are the strings that encode
+system behavior. In mini-ork's architecture, these are:
+
+| GEPA concept | mini-ork equivalent |
+|---|---|
+| `candidate: dict[str, str]` | Recipe prompt fields: `{"planner_prompt": "...", "synthesizer_prompt": "...", "verifier_contract": "..."}` |
+| `DataInst` (training example) | A task spec (kickoff JSON) from `epics` or a test task |
+| `Trajectory` | An `execution_traces` row (or bundle of rows for a run) |
+| `RolloutOutput` | `{status, process_reward, reviewer_verdict, files_written, cost_usd}` |
+| `score: float` | `process_reward` or a composite metric derived from the PRM |
+| `reflective_dataset record` | Serialized trace fields + LLM node outputs + failure summary |
+
+### 4.2 New File: `lib/gepa_optimizer.sh`
+
+This would be the A/B-selectable entry point for the reflective prompt evolution
+loop. It would expose:
+
+```bash
+# Run one GEPA optimization iteration on a named recipe's prompt parameters
+# MO_OPTIMIZER=gepa enables this path; MO_OPTIMIZER=grpo (default) keeps existing behavior
+gepa_run_iteration <recipe_name> <task_class>
+    # 1. Read candidate from prompt_win_rates / recipe prompts store
+    # 2. Sample a minibatch of recent task runs
+    # 3. Evaluate candidate on minibatch (re-runs or uses cached traces)
+    # 4. Build reflective dataset from execution_traces
+    # 5. Call reflection LM to propose new prompt text
+    # 6. Evaluate mutation on same minibatch
+    # 7. Accept/reject; if accepted, run full valset and update prompt_win_rates
+```
+
+The `MO_OPTIMIZER=gepa` env var acts as the A/B flag — existing GRPO writeback in
+`bin/mini-ork-execute` lines 218 and 252 runs unchanged; GEPA is a second writer
+targeting recipe prompts rather than lane routing.
+
+### 4.3 New File: `lib/gepa_adapter.sh`
+
+This implements the three GEPAAdapter methods in bash/Python, wiring to existing
+mini-ork infrastructure:
+
+**`gepa_evaluate()`** — wraps `bin/mini-ork run` or replays cached
+`execution_traces` rows, returns `process_reward` as the per-example score.
+Captures trace rows as the trajectory object.
+
+```bash
+gepa_evaluate() {
+  local recipe="$1" candidate_json="$2" minibatch_task_ids="$3"
+  # For each task_id in minibatch:
+  #   - if trace exists in execution_traces: use cached process_reward
+  #   - else: dispatch run and record trace
+  # Output: JSON array of {score, trace_id}
+}
+```
+
+**`gepa_make_reflective_dataset()`** — converts execution traces into feedback
+records. Uses the existing fields from `execution_traces`:
+
+```bash
+gepa_make_reflective_dataset() {
+  # For each trace_id, fetch:
+  #   - node_type, status, tool_calls, files_written, reviewer_verdict
+  #   - LLM output text (from llm_calls table if available)
+  #   - process_reward
+  # Format as:
+  # { "Inputs": {task_description}, "Generated Outputs": {node_output},
+  #   "Feedback": "process_reward=0.2, reviewer_verdict=REJECT, error=..." }
+}
+```
+
+This reuses the data already written by `prm_score_trace` and `gradient_extract` —
+no new trace infrastructure needed.
+
+**`gepa_propose_new_texts()`** — calls mini-ork's existing `llm-dispatch.sh`
+with the reflection prompt:
+
+```bash
+gepa_propose_new_texts() {
+  local component="$1" current_prompt="$2" reflective_dataset_json="$3"
+  # Use the InstructionProposalSignature template verbatim:
+  # Substitute <curr_param> = current_prompt
+  # Substitute <side_info> = reflective_dataset_json formatted as markdown
+  # Dispatch through: llm-dispatch.sh with reflection_lm (e.g., opus)
+  # Parse result: extract text between ``` blocks
+}
+```
+
+### 4.4 Integration into `lib/reflection_pipeline.sh`
+
+The existing `reflection_run` function in `lib/reflection_pipeline.sh` already
+orchestrates a six-step pipeline (extract gradients → deduplicate → link failures
+→ detect stale → summarize patterns → suggest promotions). GEPA would be wired
+in as a parallel track after step 1, when `MO_OPTIMIZER=gepa`:
+
+```bash
+# In reflection_run():
+reflection_extract_gradients "$since_ts"      # existing step 1
+
+if [ "${MO_OPTIMIZER:-grpo}" = "gepa" ]; then
+  # GEPA parallel track: reflective prompt evolution
+  gepa_run_iteration "$recipe_name" "$task_class"
+fi
+
+# GRPO track: existing steps 2-6
+reflection_deduplicate ...
+reflection_suggest_promotions ...
+```
+
+The GEPA track writes improved prompt texts to a new column `prompt_candidates`
+in the existing `gradient_records` table (or a new `gepa_candidates` table),
+analogous to how `gradient_records` stores suggested changes for human/LLM review.
+
+### 4.5 Recipe Prompts as "Textual Parameters"
+
+Mini-ork stores recipe node prompts in YAML files under `recipes/` and in
+`prompts/` templates. For GEPA evolution, each evolving component maps to:
+
+| Component name | Source |
+|---|---|
+| `"planner_prompt"` | `prompts/planner.md` template |
+| `"synthesizer_prompt"` | `prompts/synthesizer.md` |
+| `"verifier_contract"` | `prompts/verifier.md` or inline in recipe |
+| `"kickoff_framing"` | Kickoff template for a given task class |
+
+These texts are the `candidate: dict[str, str]` GEPA optimizes. Each GEPA
+iteration reads the current version, evaluates it against recent task traces,
+and proposes an improved version. The improved version is written back to the
+prompts store (initially as a candidate, promoted to default only after passing
+acceptance and validation gates).
+
+### 4.6 Wiring to Existing Reward Signals
+
+mini-ork already produces all the reward signals GEPA needs:
+
+- **Per-example score:** `execution_traces.process_reward` (produced by
+  `lib/process_reward.sh::prm_score_trace` after every node dispatch).
+  No change needed — this becomes GEPA's `scores: list[float]`.
+
+- **Trajectory / trace:** `execution_traces` rows for a run bundle. The
+  `gepa_make_reflective_dataset` function serializes these into feedback records.
+  Existing `gradient_extractor.sh::gradient_extract` already LLM-reads traces
+  and extracts change signals — GEPA's reflective dataset is a structured version
+  of the same information.
+
+- **Reflection LM:** Already used in `gradient_extractor.sh` and `reflection-refiner.sh`.
+  GEPA's reflection LM call uses the same dispatch path (`llm-dispatch.sh`), just
+  with the `InstructionProposalSignature` template.
+
+### 4.7 Pareto Candidate Pool in mini-ork
+
+GEPA's Pareto-front selection requires tracking multiple candidate prompt versions
+against multiple validation examples. In mini-ork this maps to:
+
+- **Candidate pool:** A new table `gepa_prompt_candidates (candidate_id, recipe, component, text, valset_scores_json, created_at)`. Each accepted GEPA mutation adds one row.
+- **Pareto front:** Computed at selection time — for each validation task, find which candidate scored best; a candidate is on the Pareto front if it is not dominated on all tasks.
+- **Selection:** Sample from Pareto-front candidates proportional to number of tasks where they are best — same algorithm as `select_program_candidate_from_pareto_front` in `gepa_utils.py`.
+
+This is a clean addition: it does not touch the existing `agent_performance_memory`
+or `prompt_win_rates` tables (which remain the GRPO track).
+
+### 4.8 A/B Gate and Rollout Budget
+
+The key cost-control parameters mirror GEPA's:
+
+```bash
+MO_OPTIMIZER=gepa                  # default: grpo (existing behavior)
+MO_GEPA_MINIBATCH_SIZE=10          # examples per subsample (GEPA default ~10-20)
+MO_GEPA_MAX_METRIC_CALLS=150       # total evaluations budget per recipe per run
+MO_GEPA_REFLECTION_LM=opus         # model for reflective mutation step
+MO_GEPA_CANDIDATE_COMPONENTS=planner_prompt,synthesizer_prompt  # which components to evolve
+```
+
+The minibatch guard (Phase 6, acceptance test on subsample before full-valset) is
+the primary cost mechanism — it means only ~10–20% of mutation attempts incur a
+full-valset evaluation.
+
+### 4.9 Rollout-to-Existing-Trace Reuse
+
+Mini-ork already has a dense historical trace store. GEPA's minibatch evaluation
+step (Phase 3) can be **fully cache-served** from `execution_traces` for historical
+task runs — no new LLM dispatch needed. Only novel tasks (not yet in
+`execution_traces`) require live dispatch. This further reduces GEPA's rollout cost
+for mini-ork below the baseline 100–500 GEPA evaluations, because most "evaluations"
+are SQL reads against the existing trace store.
+
+The `optimize_anything_adapter.py` in GEPA already implements this pattern
+(`_call_evaluator` with `cache_mode="memory"` or `"disk"`); mini-ork's version
+uses `execution_traces` as the persistent cache.
+
+### 4.10 Migration Path (Three Phases)
+
+**Phase 0 (scaffolding, no behavior change):**
+- Add `lib/gepa_adapter.sh` with `gepa_evaluate`, `gepa_make_reflective_dataset`,
+  `gepa_propose_new_texts` (backed by existing `execution_traces` and `llm-dispatch.sh`).
+- Add migration for `gepa_prompt_candidates` table.
+- Wire `MO_OPTIMIZER` env gate — no-op when `grpo`.
+
+**Phase 1 (shadow mode):**
+- Enable `MO_OPTIMIZER=gepa` in a test environment.
+- Run GEPA iterations on historical traces (no live task dispatches — fully cache-served).
+- Log proposed mutations to `gepa_prompt_candidates` table; do not promote to default.
+- Compare GEPA-proposed prompts to human-reviewed `gradient_records.suggested_change` —
+  measure overlap as a sanity check.
+
+**Phase 2 (A/B production):**
+- Enable `MO_OPTIMIZER=gepa` for one recipe per task class.
+- Let GEPA evolve that recipe's prompts alongside GRPO's lane routing.
+- Measure: (a) process_reward improvement on the GEPA-evolved recipe vs control;
+  (b) total evaluation cost vs the equivalent GRPO update cycle.
+- Promote winning candidates to `prompts/` on gate-pass.
+
+---
+
+## 5. Key Differences Between GEPA's Design and mini-ork's Existing Loop
+
+| Axis | GEPA | mini-ork GRPO |
+|---|---|---|
+| What is optimized | Textual prompt parameters | Lane routing weights (`relative_advantage`) |
+| Optimization target per iteration | Recipe prompt text | Which model lane to use for a node |
+| Signal used for mutation | Full trace text → LLM reflection | Scalar reward → group z-score |
+| Candidate pool | Multi-member Pareto front of prompt versions | Single "best lane" per (task_class, node_type) |
+| Cost-control mechanism | Minibatch acceptance gate | Sample size threshold (≥3) |
+| Convergence | ~100–500 evaluations | Requires dense per-lane trace history |
+
+GEPA and GRPO are **complementary**, not competing:
+- GRPO selects *which model* to run a node on (lane routing).
+- GEPA selects *what the node is told to do* (prompt text evolution).
+
+Both consume `execution_traces` and `process_reward`; neither interferes with the
+other's write path.
+
+---
+
+## 6. Files Changed / Added Summary

+|---|---|---|
+| `lib/gepa_adapter.sh` | Add | GEPAAdapter implementation: evaluate, make_reflective_dataset, propose_new_texts |
+| `lib/gepa_optimizer.sh` | Add | Main GEPA loop: Pareto select → minibatch → reflect → mutate → accept/reject |
+| `lib/reflection_pipeline.sh` | Edit (add branch) | Wire GEPA track after step 1 when `MO_OPTIMIZER=gepa` |
+| `migrations/NNNN_gepa_candidates.sql` | Add | `gepa_prompt_candidates` table |

+# Impl analysis 04 — Semantic / long-term agent memory (mem0)
+
+**Gap targeted:** mini-ork's "memory" is a SQLite run-ledger (traces, gradients, failure
+records, perf stats — `lib/memory.sh`, `lib/pattern_store.sh`, `state.db`). It has no
+*semantic* layer: it can't extract durable facts/learnings from a run and later retrieve the
+relevant ones by meaning at plan time. mem0 is the most popular universal agent-memory layer.
+
+**Source read:** `/private/tmp/miniork-ref-analysis/mem0` — `mem0/mem0/memory/main.py`
+(`class Memory`, `add()` @716, `_add_to_vector_store()` @830, `search()` @1326).
+
+---
+
+## A. How mem0 works (real code)
+
+### `add(messages, *, user_id|agent_id|run_id, infer=True, ...)`  (@716)
+Memory is **scoped** by one of `user_id / agent_id / run_id` (required). With `infer=True`
+(default), it doesn't store raw text — it runs an **LLM extract→reconcile** pipeline; with
+`infer=False` it stores raw.
+
+### `_add_to_vector_store()` — the extract + ADD/UPDATE/DELETE reconcile (@830)
+The interesting part. Per add:
+1. `parsed_messages = parse_messages(messages)` and pull short-term context
+   `last_messages = self.db.get_last_messages(session_scope, limit=10)`.
+2. **Find related existing memories first:** `query_embedding = embedding_model.embed(parsed_messages,"search")`;
+   `existing_results = vector_store.search(query=parsed_messages, filters=search_filters, ...)`.
+3. **LLM fact extraction:** system `ADDITIVE_EXTRACTION_PROMPT` (+`AGENT_CONTEXT_SUFFIX`),
+   user prompt from `generate_additive_extraction_prompt(new_messages, last_k_messages)` →
+   `llm.generate_response(...)` returns the salient facts.
+4. **Reconcile vs existing:** the model decides per fact whether it's a new `ADD`, an `UPDATE`
+   of an existing memory, a `DELETE` (contradiction), or `NOOP` — returning events like
+   `{"id":..., "memory":..., "event":"ADD"|"UPDATE"|"DELETE"}`.
+5. **Embed + persist:** `embedding_model.embed_batch(mem_texts,"add")` then `_create_memory`
+   into the vector store (raw messages also saved via `db.save_messages`).
+
+So memory isn't an append log — it's a **deduped, self-correcting fact set** maintained by an LLM.
+
+### `search(query, *, filters={user_id|agent_id|run_id}, top_k=20, rerank=False)` (@1326)
+Embed the query → `vector_store.search` filtered by scope → ranked memories (optional rerank,
+optional graph traversal when a graph store is configured). Filters MUST include a scope id.
+
+### Storage model
+Pluggable **vector store** (Qdrant/pgvector/chroma/sqlite-vec/…) for semantic recall + an
+optional **graph store** (Neo4j/Kuzu via the `graphiti`-style path) for entity relations.
+Everything carries `user_id/agent_id/run_id` + metadata for scoped retrieval.
+
+---
+
+## B. Contrast with mini-ork
+- mini-ork stores *structured run telemetry* (rewards, gradients, failures) keyed by
+  task_class/recipe — great for the GRPO loop, but it's **exact-match/SQL**, not semantic.
+  It can't answer "what did we learn before that's *relevant* to this new kickoff?"
+- mem0 stores *natural-language learnings* with embeddings + an LLM reconcile step → semantic
+  recall + self-dedup. Complementary, not a replacement.
+
+mini-ork actually already has the *human* analog: the `~/.claude/.../memory/*.md` notes with a
+`description` used "to decide relevance during recall." mem0 is the automated, embedded version
+of exactly that.
+
+---
+
+## C. Adoption plan for mini-ork (additive layer over the SQLite ledger)
+
+### New: `lib/semantic_memory.sh` with three ops mirroring mem0
+```
+mo_mem_add   "<text or trace>" --scope objective_domain=<d> [--infer]   # extract+reconcile+embed
+mo_mem_search "<query>" --scope objective_domain=<d> --top-k N          # semantic recall
+mo_mem_gc    --scope ...                                                 # expire/dedup
+```
+- **Embedding/vector backend that fits a bash tool:** `sqlite-vec` (a SQLite extension) is the
+  natural fit — keeps everything in the existing `state.db` family, no new service, queryable.
+  Fallback: a tiny local embedding service or pgvector if a PG seam already exists (the
+  shared-brain RLM already contemplates a `policy_store` PG seam).
+- **Reuse mini-ork's LLM dispatch** (`lib/llm-dispatch.sh`) for the extract+reconcile call,
+  with a mem0-style ADD/UPDATE/DELETE prompt, on a cheap lane (minimax/glm).
+
+### Where it plugs into the lifecycle
+1. **reflect → improve stage** (`bin/mini-ork-reflect`): after a run, `mo_mem_add` the durable
+   learnings (what worked, the gotcha, the decision) scoped by `objective_domain` — the same
+   partition the shared-brain RLM already uses.
+2. **plan / context-assembly** (`lib/context_assembler.sh`): before planning, `mo_mem_search`
+   the kickoff text and inject the top-K relevant prior learnings into the planner context —
+   so the orchestrator stops repeating past mistakes.
+3. Scope by `objective_domain` (not user) to match the consumer-agnostic shared brain; tag with
+   recipe + run_id for provenance.
+
+### Why this is the right shape
+- Keeps the auditable SQL ledger as source of truth; semantic memory is a derived recall index.
+- The LLM-reconcile (ADD/UPDATE/DELETE) prevents the memory from bloating into a noisy log —
+  directly relevant since mini-ork runs produce huge trace volume.
+- Closes the loop the human memory notes already prove valuable, but automatically.
+
+**Effort:** med (sqlite-vec wiring + extract/reconcile prompt + two call sites). **Payoff:**
+cross-run learning by *meaning*, not just task_class match; fewer repeated failures.

+# 05 — LLM Council Panel Bias: Analysis and mini-ork Adoption Plan
+
+**Date:** 2026-06-30
+**Source analysed:** `/private/tmp/miniork-ref-analysis/llm-council`
+**mini-ork files read:** `lib/coalition_gate.sh`, `lib/krippendorff_alpha_gate.sh`,
+`lib/refute_or_promote_gate.sh`, `recipes/recursive-validate-impl/workflow.yaml`,
+`recipes/recursive-validate-impl/prompts/tier4-panel-review.md`,

+
+---
+
+## 1. The LLM-Council Flow — Concrete Code Walk
+
+### Source map
+
+```
+backend/config.py       → COUNCIL_MODELS, CHAIRMAN_MODEL
+backend/openrouter.py   → query_model(), query_models_parallel()
+backend/council.py      → stage1_, stage2_, stage3_, run_full_council()
+backend/main.py         → HTTP endpoint, streaming SSE wrapper
+```
+
+### Stage 1 — parallel fan-out
+
+```python
+# council.py:8-32
+async def stage1_collect_responses(user_query):
+    messages = [{"role": "user", "content": user_query}]
+    responses = await query_models_parallel(COUNCIL_MODELS, messages)
+    ...
+```
+
+`query_models_parallel` (openrouter.py:56-79) creates one async task per model and
+awaits all with `asyncio.gather`. Every model in `COUNCIL_MODELS` (gpt-5.1, gemini-3-pro,
+claude-sonnet-4.5, grok-4) receives the raw user query with no cross-visibility.
+No shuffle, no position injection at this stage.
+
+### Stage 2 — anonymized cross-review + ranking
+
+```python
+# council.py:35-112
+labels = [chr(65 + i) for i in range(len(stage1_results))]  # A, B, C, D
+label_to_model = {f"Response {label}": result['model']
+                  for label, result in zip(labels, stage1_results)}
+
+responses_text = "\n\n".join([
+    f"Response {label}:\n{result['response']}"
+    for label, result in zip(labels, stage1_results)
+])
+```
+
+The ranking prompt presents all four responses as "Response A … Response D"
+with NO model names. Every council member (including the one that produced that
+response) reviews all of them under these neutral labels.
+
+The prompt text enforces a strict output format:
+
+```
+FINAL RANKING:
+1. Response C
+2. Response A
+3. Response B
+```
+
+`parse_ranking_from_text` extracts this section with a regex and falls back to
+scanning the whole text for `Response [A-Z]` patterns.
+
+Each model's ranking call is again fired in parallel via `query_models_parallel`.
+The ranking prompt text — and therefore the ordering of responses A→D — is
+**identical for every reviewer**. There is **no position randomisation**: response A
+is always first.
+
+### Rank aggregation — `calculate_aggregate_rankings`
+
+```python
+# council.py:211-254
+for ranking in stage2_results:
+    parsed_ranking = parse_ranking_from_text(ranking['ranking'])
+    for position, label in enumerate(parsed_ranking, start=1):
+        if label in label_to_model:
+            model_positions[model_name].append(position)
+
+aggregate.sort(key=lambda x: x['average_rank'])   # lower is better
+```
+
+This is a simple **Borda-style average-position aggregation**: each reviewer's
+rank-1 contributes position=1, rank-4 contributes position=4. The aggregate is
+the arithmetic mean across all reviewers. No weighting, no Condorcet, no
+tie-breaking.
+
+The aggregate ranking is written to `metadata["aggregate_rankings"]` and passed
+to stage 3, but the chairman prompt does NOT force the chairman to follow it —
+the prompt says "consider … the peer rankings and what they reveal about
+response quality".
+
+### Stage 3 — chairman synthesis
+
+```python
+# council.py:115-174
+chairman_prompt = f"""
+...
+STAGE 1 - Individual Responses:
+{stage1_text}            # ← model names RESTORED
+
+STAGE 2 - Peer Rankings:
+{stage2_text}            # ← contains raw ranking prose (model names visible again)
+"""
+response = await query_model(CHAIRMAN_MODEL, messages)
+```
+
+Critically, the chairman's prompt **de-anonymises**: it shows `Model: openai/gpt-5.1`
+in both stage 1 and stage 2 sections. The chairman (gemini-3-pro) therefore
+knows whose work it is reading when it synthesizes the final answer, reintroducing
+the identity-bias that anonymization in stage 2 was meant to prevent.
+
+---
+
+## 2. Bias Mitigation Details — What the Council Does and Does Not Do
+
+| Mechanism | Council does it? | Details |
+|---|---|---|
+| Answer anonymization (stage 2 reviewers) | Yes | Letter labels A-D; model names stripped from ranking prompt |
+| Self-review included | Yes | Each model ranks its own answer alongside others (can't recognize it as its own) |
+| Position randomization (shuffle A-D order) | **No** | Order follows insertion order of stage1_results dict, which follows COUNCIL_MODELS list order |
+| Chairman anonymization (stage 3) | **No** | Model names restored in chairman prompt |
+| Inter-rater agreement check | **No** | No α or ρ measurement |
+| Family-diversity enforcement | **No** | Models chosen by config, no enforcement gate |
+| Self-ranking exclusion | **No** | Models rank all responses including own (but can't identify it) |
+| Aggregate used to constrain synthesis | **No** | Aggregate is metadata only; chairman ignores it by policy |
+
+The council's anonymization is its central bias-mitigation contribution. The
+positional-bias gap (A always wins because it's read first) and the chairman's
+de-anonymization are the two clearest weaknesses.
+
+---
+
+## 3. mini-ork Current Panel Architecture
+
+### Tier 4 workflow (from `workflow.yaml`)
+
+```
+tier4_glm  ─┐
+tier4_kimi  ─┤  (parallel)  →  tier4_quorum  →  tier4_synth (reviewer/opus)
+tier4_codex ─┤
+tier4_minimax┘
+```
+
+- **`tier4-panel-review.md`** — each lens reads the SAME implementer artifacts
+  (`tier1-evidence.log`, `tier2-evidence.log`, etc.) and produces its own verdict
+  file (`tier4-glm.md`, etc.). Lenses do NOT read each other's reports.
+- **`tier4-panel-synthesizer.md`** — the synth node (reviewer lane, currently
+  opus) reads all four files with model names visible in file paths
+  (`tier4-glm.md` → family=zhipu is in the filename). The synthesizer prompt
+  includes composition rules but no instruction to ignore lens identity.
+- **`tier4_quorum` verifier** — counts present and non-empty lens files;
+  passes if ≥ `MO_TIER4_QUORUM` (default 3 of 4). Addresses I-1 (missing-lens
+  stall) but not bias.
+
+### Existing gates and what they catch
+
+| Gate | File | What it catches | What it misses |
+|---|---|---|---|
+| `coalition_gate` | `lib/coalition_gate.sh` | ρ ≥ 0.25 (correlated outputs), family_count < lens_count | Reviewer positional bias; intra-stage cross-review |
+| `krippendorff_alpha_gate` | `lib/krippendorff_alpha_gate.sh` | Low inter-rater agreement (α < 0.4) across lens_scores in panel-verdict.json | Bias in HOW scores are assigned; order effects |
+| `refute_or_promote_gate` | `lib/refute_or_promote_gate.sh` | Hallucinated fabrication markers surviving into findings | Systematic reviewer preference for certain families |
+| `tier4_quorum` verifier | `verifiers/tier4-panel-quorum.sh` | Missing/empty lens reports (I-1 quorum failure) | Systematic bias in the synth node (I-6) |
+
+**Gap the council addresses that mini-ork does not**: The council's stage 2
+creates a cross-review signal — each model's assessment of the OTHER models'
+work. mini-ork's lenses never read each other. The synth node receives four
+independent verdicts and must judge their relative weight without any
+cross-validated ranking. This is where **I-6 (reviewer bias)** lives: the
+synthesizer may weight one lens more heavily based on name/family, not on
+peer-validated quality.
+
+---
+
+## 4. Adoption Plan — Concrete Changes
+
+### 4a. Anonymized Cross-Review Between Lenses
+
+**What to add:** A new library `lib/panel_cross_review.sh` and a new
+`tier4_cross_review` node that fires after all four tier-4 lens reports exist
+but before `tier4_quorum`.
+
+**Mechanism:**
+
+1. Read all available `tier4-{family}.md` files from `$MINI_ORK_RUN_DIR`.
+2. Assign letter labels (A–D), randomly permuting the order each run
+   (`shuf` or `python3 -c "import random; ..."`). Store the mapping in
+   `$MINI_ORK_RUN_DIR/panel-label-map.json`.
+3. Build an anonymized cross-review prompt that presents each report as
+   "Lens Report A … Lens Report D" with the family name stripped, asking
+   each lens to rank the others. (The lens reviews all reports including
+   its own, but cannot identify its own because the file contents have
+   no self-identifying header beyond family-specific phrasing — this
+   is imperfect but mirrors the council's approach.)
+4. Run the cross-review fan-out in parallel: dispatch the same anonymized
+   ranking prompt to all four lenses via the existing `dispatch.sh`
+   machinery with model lanes `glm_lens`, `kimi_lens`, `codex_lens`,
+   `minimax_lens`.
+5. Write each ranking to `$MINI_ORK_RUN_DIR/tier4-xrank-{family}.md`.
+6. Call `lib/rank_aggregate.sh` (see 4c) to compute the Borda aggregate.
+   Write output to `$MINI_ORK_RUN_DIR/panel-rank-aggregate.json`.
+
+**Workflow change in `recipes/recursive-validate-impl/workflow.yaml`:**
+
+```yaml
+# Add after tier4_minimax, before tier4_quorum:
+- { name: tier4_cross_review, type: researcher,
+    model_lane: all_lenses_parallel,         # new multi-lane entry
+    prompt_ref: prompts/tier4-cross-review.md,
+    dispatch_mode: parallel, gates: [budget_gate] }
+
+# Edges:
+- { from: tier4_glm,          to: tier4_cross_review, edge_type: supplies_context_to }
+- { from: tier4_kimi,         to: tier4_cross_review, edge_type: supplies_context_to }
+- { from: tier4_codex,        to: tier4_cross_review, edge_type: supplies_context_to }
+- { from: tier4_minimax,      to: tier4_cross_review, edge_type: supplies_context_to }
+- { from: tier4_cross_review, to: tier4_quorum,       edge_type: supplies_context_to }
+```
+
+**New prompt `prompts/tier4-cross-review.md`:**
+
+```markdown
+# Tier 4 — anonymized cross-review and ranking
+
+You are reviewing N anonymized lens reports that assessed the same implementation.
+The reports are labelled A, B, C, D — you do not know which family wrote which.
+
+Read `${MINI_ORK_RUN_DIR}/panel-anon/lens-{A,B,C,D}.md`.
+
+Rank the reports from most to least rigorous.  Output FINAL RANKING as:
+1. Lens A
+2. Lens C
+...
+
+Then explain in 2-3 sentences what distinguished the top-ranked report.
+Write to `${MINI_ORK_RUN_DIR}/tier4-xrank-{YOUR_FAMILY}.md`.
+```
+
+The anonymization step (stripping family names from lens report headers before
+writing to `panel-anon/lens-X.md`) belongs in `lib/panel_cross_review.sh`.
+
+**Connects to:** I-1 (cross-review adds a second quorum dimension — if fewer
+than 3 cross-rankings arrive, `tier4_quorum` can count them as missing), I-6
+(anonymization removes family-identity signal during peer review).
+
+---
+
+### 4b. Position Randomization and Bias Controls in the Arbiter
+
+**Problem:** `tier4_synth` currently reads lens reports in a fixed order
+determined by the prompt template literal. If the synthesizer has positional
+recency/primacy bias, the family whose report appears first/last in the prompt
+will be systematically over-weighted.
+
+**Changes in `lib/panel_permuter.sh` (new, ~50 lines):**
+
+```bash
+mo_permute_panel_inputs() {
+  local run_dir="${1:?}"
+  local families=(glm kimi codex minimax)
+  # Fisher-Yates via python3 random.shuffle — reproducible with PANEL_SEED
+  local seed="${PANEL_SEED:-$(date +%s%N)}"
+  local order
+  order=$(python3 -c "
+import random, sys
+f = sys.argv[1:]
+random.seed(int(sys.argv[0]))
+random.shuffle(f)
+print(' '.join(f))
+" "$seed" "${families[@]}")
+  # Write shuffled order to run_dir so the synth prompt includes it
+  echo "$order" > "${run_dir}/panel-input-order.txt"
+  echo "$seed"  > "${run_dir}/panel-seed.txt"
+}
+```
+
+The synthesizer node runner reads `panel-input-order.txt` and constructs the
+prompt by concatenating lens reports in that order — not alphabetically by
+family name. The synthesizer never sees "glm first, kimi second"; it sees
+whichever random order was drawn.
+
+**Additional bias controls for the synth prompt
+(`prompts/tier4-panel-synthesizer.md`):**
+
+Add this rule block:
+
+```markdown
+## Bias controls (MANDATORY)
+
+- The lens reports are presented in random order. Do not infer quality
+  from position (first/last).
+- A cross-review ranking aggregate is in `panel-rank-aggregate.json`.
+  Use it as a signal — it represents peer assessment of rigor, not
+  your own judgment of family.
+- Cite only evidence anchors (file:line, command output) — never cite
+  "the kimi report says" as evidence. Cite what kimi's report CONTAINS.
+- Hard-rule violations: ANY single lens flagging a violation triggers
+  panel-level violation regardless of other lenses (per existing rule).
+  Do NOT override this with aggregate ranking.
+```
+
+**Connects to:** I-6 (systematic reviewer bias in synth).
+
+---
+
+### 4c. Rank Aggregation in the Arbiter
+
+**New library `lib/rank_aggregate.sh`:**
+
+Reads `tier4-xrank-{glm,kimi,codex,minimax}.md` files, parses the
+`FINAL RANKING:` sections (same regex as llm-council's `parse_ranking_from_text`),
+and computes Borda counts across all participating reviewers.
+
+```bash
+mo_aggregate_panel_ranks() {
+  local run_dir="${1:?}"
+  local label_map="${run_dir}/panel-label-map.json"
+  local xrank_dir="${run_dir}"
+  # Python inline: parse FINAL RANKING sections, average positions,
+  # map labels back to families via label_map, emit JSON.
+  python3 - "$run_dir" "$label_map" <<'PY'
+import json, re, os, sys
+
+run_dir, label_map_path = sys.argv[1], sys.argv[2]
+with open(label_map_path) as f:
+    label_to_family = json.load(f)  # {"A": "glm", "B": "codex", ...}
+
+family_positions = {}
+for reviewer in ["glm", "kimi", "codex", "minimax"]:
+    xrank_file = os.path.join(run_dir, f"tier4-xrank-{reviewer}.md")
+    if not os.path.isfile(xrank_file):
+        continue
+    text = open(xrank_file).read()
+    if "FINAL RANKING:" not in text:
+        continue
+    section = text.split("FINAL RANKING:")[1]
+    ranked = re.findall(r'\d+\.\s*Lens ([A-Z])', section)
+    for pos, label in enumerate(ranked, start=1):
+        family = label_to_family.get(label)
+        if family:
+            family_positions.setdefault(family, []).append(pos)
+
+aggregate = []
+for family, positions in family_positions.items():
+    aggregate.append({
+        "family": family,
+        "average_rank": round(sum(positions) / len(positions), 3),
+        "borda_score": sum(len(family_positions) + 1 - p for p in positions),
+        "review_count": len(positions),
+    })
+aggregate.sort(key=lambda x: x["average_rank"])
+print(json.dumps({"aggregate_rankings": aggregate}, indent=2))
+PY
+}
+```
+
+Output: `$MINI_ORK_RUN_DIR/panel-rank-aggregate.json`
+
+**Feeding the aggregate into `tier4_synth`:** The synthesizer prompt already
+references `${MINI_ORK_RUN_DIR}` for all its inputs. Adding a line to the
+synthesizer prompt:
+
+```markdown
+Read `panel-rank-aggregate.json` for the Borda-count peer ranking. When
+two lenses give contradictory verdicts on a DoD probe, the lens with the
+lower average_rank (higher peer esteem) should be treated as the stronger
+signal, unless the other lens has direct command output evidence.
+```
+
+This is a soft signal — it informs but does not override the existing hard
+rules (any single ESCALATE triggers panel-level ESCALATE; any hard-rule
+violation is absolute). It directly addresses the "how to weight conflicting
+lenses" ambiguity in the current synthesizer.
+
+**Mapping to `krippendorff_alpha_gate`:** The gate currently reads
+`panel-verdict.json`'s `lens_scores` field. The cross-review rankings can
+be converted to numeric scores (1 = rank 1 = score N, rank N = score 1)
+and written into `lens_scores` so the existing α gate measures inter-rater
+agreement of the CROSS-REVIEW, not just the primary review. This closes the
+loop: if α is low, it means reviewers disagree even on which other reports
+are high-quality — a strong signal to escalate.
+
+---
+
+## 5. Gap Summary — Council vs mini-ork
+
+| Gap | Council's approach | mini-ork current | Adoption change |
+|---|---|---|---|
+| No cross-review between lenses | Stage 2 every lens ranks others | Lenses review artifact only | Add `tier4_cross_review` node + `lib/panel_cross_review.sh` |
+| Positional bias in synth | Not fixed (known gap) | Fixed order by family name | Add `lib/panel_permuter.sh`, shuffle before synth |
+| Chairman/synth sees model identity | De-anonymized in stage 3 (gap) | Synth sees family names in filenames | Strip family IDs from report headers in `panel-anon/` shadow dir |
+| Rank aggregation not used by synth | Aggregate passed as metadata only | No ranking at all | Add `lib/rank_aggregate.sh`, feed Borda scores into synth prompt |
+| No α on cross-review signal | N/A | `krippendorff_alpha_gate` runs on primary scores | Write cross-review ranks as `lens_scores` in `panel-verdict.json` for α gate |
+| Quorum covers cross-review | N/A (no cross-review) | `tier4_quorum` counts primary reports only | Extend `tier4_quorum` to also count xrank files (or separate quorum verifier) |
+
+---
+
+## 6. Issues Addressed
+
+- **I-1 (lens quorum failure):** The new cross-review node adds a second
+  dimension: `tier4_quorum` can require both primary report quorum (≥3 of 4)
+  and cross-review quorum (≥2 of 4 xrank files). Missing xrank files are already
+  caught by the same size-check pattern in `tier4-panel-quorum.sh`.
+
+- **I-6 (reviewer bias in synth):** Three changes combine:
+  (a) anonymized cross-review removes family identity during peer assessment;
+  (b) `lib/panel_permuter.sh` removes positional primacy/recency in the synth
+  prompt; (c) Borda aggregate gives the synth a peer-validated quality signal
+  to break ties without guessing by family name.
+
+---
+
+## 7. Implementation Sequence (Low-Risk Order)
+
+1. **`lib/rank_aggregate.sh`** — pure Python, no workflow changes, low risk.
+   Wire into `tier4_synth` runner as a pre-prompt step that writes
+   `panel-rank-aggregate.json` from any existing `tier4-xrank-*.md` files
+   (initially empty → aggregate is absent → synth falls back gracefully).
+
+2. **`lib/panel_permuter.sh`** — modifies how synth prompt is assembled.
+   Add `PANEL_SEED` env knob for reproducibility in tests. Wire into
+   `tier4_synth` dispatcher. Zero change to workflow YAML.
+
+3. **`prompts/tier4-panel-synthesizer.md`** — add bias-control block and
+   reference to `panel-rank-aggregate.json`. Affects prompt text only, no
+   code change.
+
+4. **`lib/panel_cross_review.sh`** + **`prompts/tier4-cross-review.md`** —
+   new node; requires workflow YAML change. Higher risk because it adds a
+   parallelism fan-out and new quorum dependency. Wrap behind
+   `MO_CROSS_REVIEW=1` feature flag initially.
+
+5. **Extend `tier4_quorum` verifier** — add optional xrank file check gated
+   on `MO_CROSS_REVIEW` env var to avoid breaking existing runs.
+
+6. **Feed cross-review scores into `krippendorff_alpha_gate`** — final
+   integration step after cross-review is stable.
+
+---
+
+## 8. Council Limitations NOT Worth Porting
+
+- **Streaming SSE** — mini-ork is a shell framework; SSE is irrelevant.
+- **Conversation storage** — mini-ork uses `MINI_ORK_DB` (SQLite) with its
+  own schema; not a gap.
+- **Title generation** — cosmetic; not a correctness concern.
+- **Chairman de-anonymization** — this is actually a gap in the council that
+  mini-ork should NOT replicate. Keep the shadow `panel-anon/` dir strategy

-# E1 — Node checkpoints: durable state + hash validity + crash-safe publish
-
-Foundation of durable DAG resume. See `internal-docs/architecture/2026-07-15-durable-dag-resume-design.md` §2–4. This epic alone kills the "rerun the whole DAG" failure and is correct on its own; E2+ build on it. Do NOT add recovery/CLI here — publish + validity only.
-
-## Goal
-Persist a crash-safe checkpoint at each node's completion, and provide a validity check that decides whether a completed node is reusable.
-
-## Requirements
-1. **Migration** adding `node_checkpoints` and `node_attempts` (design §2 shapes). Additive; legacy runs read unchanged.
-2. **Checkpoint writer seam** (Python shared runtime, callable from both bash and python execute paths): after a node completes, write artifacts → fsync → compute `sha256` of each artifact → commit the `node_checkpoints` row (input_hash, recipe_version, config_hash, artifact_manifest_json) in one transaction. Never commit the row before artifacts+manifest are durable and self-consistent.
-3. **Validity check** `is_node_reusable(run_id, node_id)`: returns reusable iff input_hash matches, recipe_version+config_hash match, and every manifest artifact exists and its sha256 verifies. Fails **closed** on any mismatch (design §3–4).
-4. **Node-attempt row** appended per attempt (result, failure_class, cost, provider_session_id). Append-only.
-5. Hook the writer into the node loop in `mini_ork/ported/mini_ork_execute.py` at node completion.
-
-## Files / areas in scope (touch ONLY these)
-- The migrations directory (new migration file) + schema doc
-- `mini_ork/ported/mini_ork_execute.py` (call the writer at node completion)
-- A new checkpoint-writer module (Python) + validity function
-- `tests/` (new unit tests)
-Do NOT add CLI, recovery, leases, or turn-resume — those are E2–E4.
-
-## Verification command
-```bash
-bash tests/run-all.sh unit && python -m pytest tests/ -q -k checkpoint
-```
-Must exit 0.
-
-## Acceptance
-- A completed node writes a `node_checkpoints` row only after its artifacts verify.
-- `is_node_reusable` returns False when an artifact is deleted or its bytes change, or when input/recipe/config hash differs.
-- Crash window 1 (artifacts exist, no row) and window 2 (row exists, artifact corrupt) both resolve to "not reusable → rerun".
-- Existing suites stay green; legacy runs with no checkpoint rows still read.

-# E2 — Dependency-closure recovery + `mini-ork recover` CLI/API
-
-Depends on E1 (`node_checkpoints` + `is_node_reusable` must exist). See design note §3, §5, §9. Adds the recovery walk and the operator entrypoint. Do NOT add leases/idempotency (E3) or turn-resume (E4) here.
-
-## Goal
-Resume a run from the earliest non-reusable node using dependency closure, reusing valid ancestors, via a new CLI/API entrypoint distinct from the cost-pause `resume`.
-
-## Requirements
-1. **Recovery planner**: given a run_id, compute the DAG from `workflow.yaml` (reuse `lib/topology.sh` / the python topology port), mark each node reusable via E1's `is_node_reusable`, find the earliest non-reusable node, and return the **dependency closure** to rerun (the node + its transitive dependents). A successful parallel branch must NOT be in the set.
-2. **`mini-ork recover <run_id> [--from-node X] [--strategy resume|retry|repair|pause]`** CLI + matching API. `resume` = from first incomplete node; `retry` = the failed node; `repair` = rerun with failure evidence + a bounded turn/cost budget; `pause` = wait for human.
-3. **`mini-ork recover --status <run_id>`**: print valid checkpoints, exactly which nodes will be **reused** vs **rerun**, and the cost boundary — WITHOUT dispatching.
-4. **Keep `mini-ork resume <run_id>` (cost pause) and steering pause unchanged and separate.** A distinct subcommand/path so the two are never conflated.
-5. Recovered nodes reuse E1 checkpoints/artifacts — no new LLM dispatch for reused ancestors.
-
-## Files / areas in scope (touch ONLY these)
-- `bin/mini-ork` + `mini_ork/ported/mini_ork_cli.py` (new `recover` subcommand)
-- A new recovery-planner module (Python)
-- `mini_ork/ported/mini_ork_execute.py` (enter the loop at the closure's first node)
-- `tests/`
-Do NOT modify the existing `resume`/steering code paths beyond calling them; do NOT add leases or turn-resume.
-
-## Verification command
-```bash
-bash tests/run-all.sh unit && python -m pytest tests/ -q -k "recover or closure"
-```
-Must exit 0.
-
-## Acceptance
-- Scenario 1 (nodes A–C checkpointed, D failed): `recover` reruns only D; A–C get zero new dispatches/LLM calls.
-- Scenario 5 (parallel DAG, one branch failed): only the failed branch + dependents rerun.
-- `recover --status` shows the reuse/rerun split and cost with no dispatch.
-- `mini-ork resume` (cost pause) behavior unchanged.

-# E3 — Single-writer lease + idempotent recovery + failure-class state machine
-
-Depends on E1+E2. See design note §5, §7. Makes recovery concurrency-safe and classifies stops. Completes the correctness foundation (E1–E3) before turn-resume (E4).
-
-## Goal
-Prevent two workers/operator-clicks from resuming the same run concurrently, make repeated recovery requests idempotent, and classify each stop so only genuinely terminal conditions fail the whole run.
-
-## Requirements
-1. **`run_leases` table + fencing**: a recovery acquires a lease (owner_token, expires_at) before any dispatch or checkpoint write. Any checkpoint/terminal write must present the current token or be **rejected**. A stale worker with an expired token cannot publish.
-2. **`recovery_requests` idempotency**: same `(run_id, from_node, strategy)` returns the in-flight/last recovery, not a duplicate dispatch.
-3. **Failure-class state machine** (design §5): classify each stopped attempt as `infra_interrupt | provider_limit | output_invalid | input_required | terminal`. First four leave a durable recovery record; only `terminal` marks the run failed. Default policy: auto-recover only `infra_interrupt`; any new LLM attempt (`provider_limit`/`repair`) is explicit + budget-bounded, never an unbounded auto-retry loop.
-4. Wire the lease around E2's recovery dispatch and E1's checkpoint publish.

-- Scenario 6 (two concurrent recovery requests): one acquires ownership; the other returns a safe descriptive result; the node runs once.
-- A stale worker cannot publish a checkpoint after a new recovery acquires the lease.
-- A `max-turns` stop is classified `provider_limit` and does NOT auto-retry unboundedly.
-- Only `terminal` marks the run failed; the other four leave a recovery record.

-# E4 — Turn-level resurrection: `claude --resume` + durable session file + tool receipts
-
-Depends on E1–E3 (the correctness foundation must exist first). See design note §1, §6. This is the operator's priority-A ("resurrect a failed node at turn 9"). It is a **continuation optimization**, not a checkpoint — scope it as such.
-
-## Goal
-Resume a failed node's agent at its interrupted turn (e.g. GLM critique that died at turn 9) by continuing the vendor session, surviving sandbox death, without re-firing side-effecting tools.
-
-## Requirements
-1. **Capture the provider session id** per node attempt (claude emits `session_id` in its JSON output) → `node_attempts.provider_session_id`.
-2. **Persist the CLI session store durably.** The claude session store is the jsonl transcript under `~/.claude/projects/<hash>/*.jsonl`. On checkpoint AND on recoverable failure, copy that jsonl into the run dir / durable store; record it as `node_checkpoints.session_ref`. On a fresh sandbox, restore the jsonl into `~/.claude/projects/…` before resuming — this is what makes turn-resume survive worker/sandbox death (design §6, scenario 2).
-3. **Resume via `claude --resume <session_id>`** for a `retry`/`repair` on a node with a session_ref. Only kicks in for lanes routed through the claude binary (opus/sonnet/kimi/minimax/glm). **codex lane: node-level resume only** in v1 (it has its own session model) — document it, don't fake it.
-4. **Tool receipts**: persist a receipt (input+output) for every side-effecting tool call BEFORE the node is considered done. On any replay, a completed non-idempotent tool returns its receipt and is NEVER re-invoked. Read-only tools may replay per strategy.
-
-## Files / areas in scope (touch ONLY these)
-- `lib/llm-dispatch.sh` + `mini_ork/dispatch/providers.py` (capture session id; add `--resume` on recovery)
-- The checkpoint writer (E1) — persist/restore the session jsonl + tool receipts
-- A new tool-receipt store (Python)
-- `tests/`
-Do NOT change node-checkpoint validity (E1) or the recovery planner (E2).

-
-## Acceptance
-- A node that stopped at max-turns resumes via `--resume <session_id>` and continues the same conversation (verified with a stub claude that asserts it received `--resume`).
-- With the session jsonl persisted, a simulated sandbox death (delete `~/.claude/projects/…`) still resumes after restore.
-- Scenario 8: a side-effecting tool that already ran is NOT re-invoked on replay — its receipt is returned.
-- codex nodes fall back to node-level resume, documented.

-# E5 — Trace continuity + UI projection + operator runbook
-
-Depends on E1–E4. See design note §8, §9, §11. Makes recovery legible: one trace, DAG-native UI, and a runbook. Ships the remaining kickoff deliverables (#4 runbook, #5 external-orchestrator handoff).
-
-## Goal
-Correlate original + recovered work under one root trace, render recovery inside the existing run DAG, and give operators a runbook to inspect/recover/cancel/diagnose without deleting valid artifacts or repeating spend.
-
-## Requirements
-1. **Trace continuity**: all LLM calls, node attempts, and recovery attempts for one logical run correlate under one **root trace**. Use the caller-supplied root trace context when present (e.g. the Researcher compose planner); preserve it across runner/sandbox boundaries. A resumed attempt creates new child/attempt spans, not a disconnected synthetic trace. run/node/checkpoint/attempt ids become queryable trace attributes.
-2. **UI projection**: recovery renders in the existing run DAG — completed nodes stay completed, the failed node shows its failed attempt + next action, new attempts nest beneath that node (not a fresh unrelated run). Read from the E1–E3 tables, not log scraping.
-3. **Operator runbook** (deliverable #4): how to inspect (`recover --status`), recover, cancel a pending recovery (without invalidating prior checkpoints), and diagnose — including the difference between cost-pause resume, steering resume, and execution recovery.
-4. **External-orchestrator handoff** (deliverable #5): a short doc on how a caller supplies a root trace, receives checkpoints, and requests recovery.
-5. `recover --cancel <request_id>`: cancels a pending recovery without invalidating previous checkpoints (scenario: cancel a pending recovery).
-
-## Files / areas in scope (touch ONLY these)
-- The trace layer (`lib/trace_store.sh` / `mini_ork` trace modules) — root-trace propagation + attempt spans
-- The web UI (`mini_ork/web/` + `ui/`) — DAG recovery projection + a by-run recovery view
-- `internal-docs/` — the operator runbook + external-orchestrator handoff docs
-- `tests/`

-## Acceptance
-- Scenario 9: original + recovered LLM calls appear under the same logical trace/run, with distinct node-attempt spans.
-- The UI shows a recovered run as one DAG with nested attempts, not two runs.
-- `recover --cancel` leaves prior checkpoints valid.
-- Runbook + handoff docs exist and cover inspect/recover/cancel/diagnose and the three resume types.

-# Durable DAG resume and recovery
-
-## Goal
-
-Make a Mini-ork run resumable from its last **validated DAG checkpoint** after a
-node, agent, runner, or sandbox failure. Recovery must reuse already-completed
-work and its artifacts instead of restarting the workflow or repaying for
-upstream LLM calls.
-
-This capability must be generic: it will be used by the Researcher compose
-planner, but it must work for ordinary Mini-ork recipes too.
-
-## Why this matters
-
-The current failure mode is expensive and misleading:
-
-- a long-running agent can hit a model turn limit after useful upstream nodes
-  completed;
-- a sandbox or worker can stop after artifacts were produced;
-- operators can currently resume a cost pause or provide steering, but cannot
-  safely resume arbitrary DAG execution from a durable node boundary;
-- re-running the whole workflow repeats prior model spend and makes the UI and
-  traces look like duplicate work.
-
-The target behaviour is: **resume the failed or first-incomplete node, never
-silently replay valid ancestors.**
-
-## Product contract
-
-### 1. A checkpoint is a safe semantic boundary
-
-Mini-ork must define and persist checkpoints only when all of the following
-are true:
-
-1. A node has produced its intended output.
-2. Required artifacts are present, non-empty where applicable, and integrity
-   checked.
-3. The node's deterministic validation/verification requirements have passed.
-4. The checkpoint contains enough provenance to decide whether it remains
-   valid for a later recovery.
-
-A partially streamed response, an in-memory agent thought, or a tool call with
-unknown side effects is **not** automatically a resumable checkpoint.
-
-Mini-ork may retain provider session ids, transcripts, tool receipts, and
-intermediate progress to make a retry cheaper. Those are optional continuation
-optimisations, not the correctness source of truth.
-
-### 2. Recovery resumes a DAG, not just a linear script
-
-For a recovery request, Mini-ork must determine the earliest node that is not
-reusable. A completed node may be skipped only if its checkpoint and all of its
-upstream inputs still match the current run's relevant inputs, recipe/workflow
-version, and configuration.
-
-For parallel DAGs, recovery must use dependency closure, not a simplistic
-"last node number" rule. An unrelated successful branch must not be rerun.
-
-### 3. Recoverable failure is not terminal failure
-
-At minimum, distinguish these outcomes:
-
-- infrastructure interruption: sandbox/worker/process disappeared or was
-  interrupted;
-- provider/agent limit: timeout, max-turns, transient provider failure, or
-  exhausted tool loop;
-- output/validation failure: a node ran but did not produce a valid checkpoint;
-- user input required: human answer or steering is needed before proceeding;
-- terminal configuration/safety failure: recovery would be unsafe or inputs
-  are incompatible.
-
-The first four must leave a durable recovery record. Only genuinely terminal
-conditions should mark the entire run failed.
-
-### 4. Recovery must be bounded and intentional
-
-Recovery must support an operator/API choice between at least:
-
-- resume unchanged from the first incomplete node;
-- retry the failed node;
-- repair the failed node with its failure evidence and a bounded turn/cost/tool
-  budget;
-- pause for a human decision.
-
-Do not turn a max-turn or no-progress result into an unbounded automatic retry
-loop. The default policy should be conservative: automatic recovery is suitable
-for deterministic/infrastructure interruptions; a new LLM repair attempt
-should be visible and bounded.
-
-### 5. Existing operator contracts stay compatible
-
-- Preserve the current `mini-ork resume <run_id>` cost-pause behaviour.
-- Preserve existing steering-pause behaviour.
-- Provide a separate, explicit entrypoint/API for execution/DAG recovery so an
-  operator cannot accidentally mistake "clear a cost pause" for "rerun a
-  workflow node".
-- Existing recipes and historical run records must remain readable.
-
-## Required capabilities
-
-### Durable run and node state
-
-Persist enough state outside a live shell process to answer, after restart:
-
-- Which run, recipe, workflow/version, input revision, and resolved
-  configuration is being recovered?
-- Which node attempts started, completed, failed, or were paused?
-- Which checkpoint is the latest valid checkpoint for each branch?
-- Which artifacts and hashes back each checkpoint?
-- Why did the latest attempt stop, and is it recoverable?
-- Which recovery request/attempt currently owns the run?
-
-The persisted state must be queryable for the UI/API and must survive a
-process or sandbox stop. Run-directory files may be used, but a durable index
-must make them inspectable without log scraping.
-
-### Atomicity and recovery after a crash
-
-Checkpoint publication must be crash-safe. Mini-ork must not mark a node
-reusable before its artifacts and checkpoint manifest are durable and valid.
-
-It must explicitly handle both crash windows:
-
-1. artifacts exist but the checkpoint was not committed; and
-2. checkpoint metadata exists but an artifact is missing or corrupt.
-
-In either case, recovery must fail closed for that node: validate and reuse it
-only when safe, otherwise rerun that node rather than trusting a partial
-record.
-
-### Single-writer execution ownership
-
-Two workers, retries, or operator clicks must not resume the same run
-concurrently. Establish a durable ownership/lease or equivalent fencing rule
-so that a stale worker cannot publish a checkpoint or terminal state after a
-new recovery attempt begins.
-
-Repeated recovery requests with the same run, checkpoint, and strategy must be
-idempotent and return the existing recovery rather than duplicate spend.
-
-### Node-level observability
-
-Expose a coherent history for every node attempt:
-
-- node id/type, attempt number, start/end times, result, and failure class;
-- checkpoint used and checkpoint produced;
-- artifact references and validation result;
-- model/provider session details and per-attempt cost where available;
-- recovery strategy, budget, and operator/system initiator.
-
-The existing event stream may remain append-only, but it must no longer be the
-only source needed to infer replay state.
-
-### Trace continuity
-
-All LLM calls, node attempts, and recovery attempts for one logical Mini-ork
-run must be correlated under one root trace. A resumed attempt should create
-new child spans/attempt spans, not a disconnected synthetic trace.
-
-Use the incoming/root trace context when one is supplied by a caller. Preserve
-it through runner/sandbox boundaries and make the run, node, checkpoint, and
-attempt identifiers queryable trace attributes.
-
-### Safe tool behaviour
-
-Never automatically replay a non-idempotent external action merely because a
-process died mid-node. Persist a receipt/output when available and require an
-explicit retry policy or human approval when side effects cannot be proven
-safe. Deterministic/read-only tools may be replayed according to the selected
-strategy.
-
-## Required user and API behaviour
-
-Mini-ork must provide a programmatic and operator-facing way to:
-
-1. inspect a run's current recovery status and valid checkpoints;
-2. see exactly which work will be reused and which node(s) will run;
-3. request a bounded recovery from a selected checkpoint/node;
-4. cancel a pending recovery without invalidating previous checkpoints;
-5. distinguish cost-pause resume, steering resume, and execution recovery;
-6. receive a clear terminal explanation if recovery cannot proceed safely.
-
-The UI should present recovery as part of the existing run DAG: completed nodes
-remain completed, the failed node shows its failed attempt and next action, and
-new attempts are nested beneath that node rather than shown as a fresh,
-unrelated run.
-
-## Acceptance scenarios
-
-Implement automated coverage for at least the following scenarios without
-calling a real paid model:
-
-1. **Failed terminal agent:** nodes A–C checkpoint successfully; node D exits
-   due to max turns. Recovering retries/repairs D only. A–C receive no new
-   dispatches or LLM calls.
-2. **Interrupted runner:** a worker dies after a validated checkpoint. A new
-   process resumes at the first incomplete node using the same logical run.
-3. **Artifact mismatch:** a checkpoint points to a deleted or corrupted
-   artifact. Recovery refuses to skip that node and reruns the smallest safe
-   dependency closure.
-4. **Changed inputs/configuration:** a changed kickoff, workflow, relevant
-   prompt/configuration, or upstream artifact invalidates affected checkpoints
-   but preserves independent valid work where safe.
-5. **Parallel DAG:** one branch fails and another succeeds. Recovery reruns
-   only the failed branch and dependent nodes.
-6. **Duplicate recovery request:** two concurrent requests cannot execute the
-   same node twice; one acquires ownership and the other returns a safe,
-   descriptive result.
-7. **Human pause:** a steering or answer-required state stays paused until
-   input arrives and then resumes without repeating valid nodes.
-8. **Non-idempotent tool:** a side-effecting tool failure is never silently
-   replayed.
-9. **Trace grouping:** original and recovered LLM calls appear under the same
-   logical trace/run, with distinct node-attempt spans.
-10. **Compatibility:** current cost-pause resume and legacy completed runs
-    continue to work unchanged.
-
-## Deliverables
-
-1. A concise architecture/design note explaining the chosen durable state
-   model, checkpoint validity rules, recovery state machine, and migration
-   compatibility strategy.
-2. The generic Mini-ork runtime capability, CLI/API/UI affordances, and test
-   coverage needed to satisfy the acceptance scenarios.
-3. A migration and rollback plan for existing state databases and legacy runs.
-4. An operator runbook: how to inspect, recover, cancel, and diagnose a
-   failed run without deleting valid artifacts or repeating completed spend.
-5. A short handoff describing how an external orchestrator (such as the
-   Researcher compose planner) supplies a root trace, receives checkpoints,
-   and requests recovery.
-
-## Technical decisions owned by Mini-ork
-
-Mini-ork should choose the implementation details, including:
-
-- database schema/table names and migration approach;
-- whether the checkpoint writer is Bash, Python, or a shared runtime seam;
-- exact CLI/API names and JSON shapes;
-- artifact storage/manifest format and integrity algorithm;
-- lease/locking/fencing mechanism;
-- retry/repair budget representation and policy hooks;
-- how the current Bash/Python parity and runtime-cutover strategy applies;
-- UI layout and event projection.
-
-The implementation must explain these choices in its design note and show how
-they meet the contracts above rather than merely adding another retry loop.
-
-## Out of scope for this kickoff
-
-- Rewriting Mini-ork into a wholly new scheduler or actor framework.
-- Guaranteeing continuation from arbitrary hidden LLM reasoning tokens.
-- Automatically replaying unsafe external side effects.
-- Changing Researcher planner business logic; that integration follows after
-  Mini-ork exposes a tested, generic recovery capability.
-
-## Definition of done
-
-The feature is complete only when the acceptance scenarios pass, a run can be
-recovered from a durable node checkpoint without replaying valid ancestors, and
-an operator can see the exact recovery decision, cost boundary, artifacts, and
-trace lineage before and after recovery.

-# Turn-jsonl trajectory store: persist every turn + link its path in the DB
-
-## Problem
-mini-ork already writes per-node turn logs to the run dir — `agent-<node>.stream.jsonl` (streamed
-turn events) and `agent-<node>.transcript.json` (final transcript), via
-`_mo_llm_persist_agent_transcript` (`lib/llm-dispatch.sh:500`), and the Python dispatch already
-handles `.stream.jsonl` paths (`mini_ork/dispatch/providers.py:403`). BUT:
-
-1. **The DB does not store a path to these files.** `llm_calls` has no `transcript_path`/`stream_path`
-   column; `execution_traces` only has `files_read/files_written/final_artifact_ref`. So the raw
-   turns are orphaned from the DB — you cannot query "give me the trajectory for this run/call"
-   without reverse-engineering the path from run_id + node naming.
-2. **Coverage is inconsistent.** The implementer node emits `.stream.jsonl`; the reviewer node only
-   got `.transcript.json`. Not every dispatched turn writes the streamed jsonl, so trajectories are
-   partial.
-3. **No retention policy.** At ~677k input tokens/run × ~255 runs/month, raw jsonl is a few MB/run
-   (~1GB/month) and the run dir grows unbounded.
-
-This layer is the precondition for the evidence bundle, trajectory eval/judge scoring, replay, and
-the insight distiller (see `internal-docs/research/2026-07-03-adding-eval-to-miniork-run-flow.md`).
-
-## Objective
-Every dispatched turn writes a `.stream.jsonl` capturing the real turn events, and each is registered
-as a queryable DB row keyed by run_id + node, with a RELATIVE path so it survives vendoring /
-foreign-home / cloud exec. Migration-aware: the schema + conventions are language-agnostic and land
-now; the canonical writer lives in the Python dispatch (`mini_ork/dispatch/telemetry.py`) where the
-migration is heading, with a minimal bash mirror only for nodes still dispatched by bash.
-
-## Deliverables
-
-### A. Schema (migration-agnostic — land first)
-1. New migration `db/migrations/00NN_run_artifacts.sql`:
-   ```
-   run_artifacts(
-     id INTEGER PRIMARY KEY,
-     run_id TEXT NOT NULL,

-   ```
-   Additive only. Do NOT touch existing tables.
-
-### B. Conventions (migration-agnostic)
-2. Normalize turn-log naming so EVERY dispatched node writes `agent-<node>.stream.jsonl` (fix the
-   reviewer/verifier gap). The stream jsonl must contain per-turn events: role, tool calls + args,
-   tool results, token usage, timing — not just the final message.
-3. Paths stored in `run_artifacts.rel_path` are relative to the run dir. A helper resolves
-   rel→abs at read time against `MINI_ORK_RUN_DIR`.
-4. Retention: gzip `.stream.jsonl` on run completion; a prune step drops raw `turn_jsonl` older than
-   `MO_TRAJECTORY_TTL_DAYS` (default 30) while KEEPING derived `evidence_bundle` rows forever.
-
-### C. Writer (migration-aligned)
-5. **Canonical write in Python**: in `mini_ork/dispatch/telemetry.py`, right after the `llm_calls`
-   row is written, insert a `run_artifacts` row (kind=`turn_jsonl`, and `transcript` if present) with
-   the relative path + bytes + sha256. Follow telemetry.py's existing schema-agnostic pattern (only
-   write if the table exists) so it is a no-op on older DBs.
-6. **Minimal bash mirror**: at the `_mo_llm_persist_agent_transcript` site in `lib/llm-dispatch.sh`,
-   insert the same `run_artifacts` row for nodes still dispatched by bash. Mark it clearly
-   `# MIGRATION: remove when this node moves to mini_ork.dispatch`. Keep it to a few lines.
-7. Both writers target the same table + same rel-path convention, so coverage is complete today and
-   the bash mirror deletes cleanly as nodes migrate.
-
-## Smoke / DoD (must pass)
-- `tests/unit/test_run_artifacts.sh` (or `tests/test_run_artifacts_py.py`): after a dispatched node,
-  a `run_artifacts` row exists with kind=`turn_jsonl`, a rel_path that resolves to a real non-empty
-  `.stream.jsonl` under the run dir, correct bytes/sha256, and NOT an absolute path.
-- Coverage: a `code-fix` run registers a `turn_jsonl` artifact for EVERY dispatched node (implementer,
-  reviewer, verifier), not just the implementer.
-- Migration is additive: existing `pytest` + bash executor tests still green; the Python telemetry
-  writer is a no-op when `run_artifacts` is absent (old DB).
-- Retention: gzip-on-complete produces `.stream.jsonl.gz`; the rel_path in the DB points at the
-  actual (possibly gzipped) file; prune leaves `evidence_bundle` rows untouched.
-
-## Constraints
-- Additive schema only; do not alter existing tables or the existing transcript-writing behavior.
-- Relative paths ONLY in the DB (portability across vendor/foreign-home/cloud).
-- The bash mirror is minimal + marked for removal; the canonical writer is Python `telemetry.py`.
-- No new runtime deps. Do not block the run if the artifact write fails (best-effort, like the
-  existing transcript persist).

-# Harsh-critic review — the ported executor + runtime cutover
-
-Adversarial cross-family panel (kimi + codex + opus) review of the bash→Python
-migration's highest-risk surface, BEFORE the live-dispatch default is flipped.
-Assume the code is theater until proven otherwise. Your job is to find where the
-Python port silently diverges from the bash it claims to replace.
-
-## Scope (read these, in order)
-
-- `mini_ork/ported/mini_ork_execute.py` — the ported executor (helpers + GRPO +
-  orchestration backbone + `dispatch_node` live routing + `main`).
-- `bin/mini-ork-execute` — the 3449-line bash original it ports.
-- `lib/runtime-select.sh` + the `mo_runtime_maybe_delegate` line wired into
-  `bin/mini-ork*` — the cutover switch.
-- `scripts/runtime-parity-harness.sh` + `scripts/live_dispatch_harness.py` — the gates.
-- `tests/unit/test_mini_ork_execute_py.py` — the tests that claim it works.
-
-## The claims to attack
-
-1. **`dispatch_node` faithfully replicates `_dispatch_node`.** It does NOT — by
-   the author's own admission it omits recipe-specific file-naming (schema-judge-panel,
-   recursive-validate-impl), the recipe dispatchers (per_feature / epic / minimal-scaffold),
-   the publisher's oracle-gates + artifact-contract commit, and trace/heartbeat
-   side-effects. For EACH omission: does it change a node's pass/fail result, the
-   artifact a downstream node reads, or a gate that blocks publish? Name a concrete
-   recipe + node where the omission produces a DIFFERENT run outcome than bash.
-2. **The live path is verified.** It is only tested with a FAKE dispatch. Find a
-   real-provider behavior (agent tool-call Writes vs stdout, gateway capture
-   coin-flip, mtime-marker preserve-agent-Write, MO_TARGET_CWD resolution) where
-   the fake test passes but a real model would break the wiring.
-3. **The reviewer verdict gate matches bash.** Compare the port's pass/revise/fail/
-   unknown mapping and the synth-never-gates branch against the bash case statement
-   line-by-line. Find a verdict string bash treats differently.
-4. **The cutover shim is safe.** Find an entrypoint where `MINI_ORK_RUNTIME=python`
-   delegates to a port that is NOT behaviorally equivalent, or where the shim breaks
-   the bash default (set -e interaction, arg forwarding, cwd, env inheritance across
-   the cascade), or a recipe dispatcher that shells `bin/mini-ork-execute` and now
-   gets the Python one mid-run.
-5. **The harness proves the cutover is safe.** It skips live dispatch and treats
-   `--help` as exit-code-only. What real divergence class does it therefore NOT catch?
-
-## Deliverable
-
-`docs/reviews/execute-port-harsh-critic-<ts>.md` with, per confirmed divergence:
-the file:line in the port, the bash line it should match, the concrete
-recipe+node+input that triggers a different run outcome, and severity
-(blocks-cutover / degrades-quality / cosmetic). End with an explicit verdict:
-is the LIVE dispatch default safe to flip, and if not, the exact must-fix list.
-
-Refute-or-promote: do not accept "looks equivalent". Every claim needs a concrete
-triggering scenario or it is dropped. A missing recipe special-case is only a
-finding if you can name the recipe that breaks.
-
-## Success criteria
-
-- Panel reviewed all scoped files (not skimmed).
-- At least the 5 claims above each get an explicit confirmed/refuted with evidence.
-- Every confirmed divergence names file:line (port) + file:line (bash) + a
-  triggering recipe/node/input.
-- Final go/no-go on flipping the live-dispatch default, with a must-fix list.

-# Feature inventory of mini-ork as a cloud agent orchestration platform
-
-## Problem
-
-mini-ork has grown into a full **cloud agent orchestration system with
-self-improvement and learning**, but there is no single authoritative
-catalog of everything it provides. Newcomers, investors, and integrators
-cannot see the whole surface at a glance. We need a comprehensive,
-code-grounded feature inventory that reads the actual implementation (not
-marketing) and enumerates every capability, organized under the umbrella
-of a cloud agent orchestration platform.
-
-## Definition of Done
-
-Produce a feature inventory that enumerates mini-ork's capabilities grouped
-under these pillars (add pillars if the code reveals more):
-
-1. **Orchestration core** — the task loop (classify → plan → execute →
-   verify → reflect → improve), recipes, workflow DAGs, node types,
-   artifact-graph contracts, gates.
-2. **Heterogeneous model dispatch** — provider lanes (codex, minimax, glm,
-   kimi, opus, sonnet, deepseek…), routing policies, cost governance,
-   budget gates.
-3. **Runtime reliability** — durable-DAG resume (step/turn), leases &
-   idempotency, tool receipts, publisher-commit, throttle/retry, rollback.
-4. **Verification & gates** — verifier nodes, gate registry, execution-
-   anchored rewards, eval-in-run-flow node, metamorphic/jury plans.
-5. **Self-improvement & learning** — the GRPO / bandit router
-   (lane_domain_advantage, lane_region_advantage), GEPA prompt evolution
-   (prompt_win_rates, promotion_records), reflection, apply-loop.
-6. **Observability surface** — `mini-ork serve` HTTP/SSE API, the runs
-   list, run detail/DAG, learning endpoints, trajectory, fingerprint.
-7. **Operator & dev ergonomics** — `bin/mini-ork` subcommands, worktree
-   dev loop, init/scaffold, validate/garden, doctor, providers config.
-
-For each feature: a one-line description + at least one `file:line` anchor
-proving it exists in the code. Mark features that are **shipped** vs
-**specced/roadmap** distinctly (do not present roadmap items as shipped).
-
-## Files in scope (read-only — this is an inventory, not a code change)
-
-- `mini_ork/` — the entire Python runtime (cli/, dispatch/, gates/,
-  learning/, memory/, web/, context.py, types.py)
-- `bin/mini-ork` — subcommand entrypoint
-- `recipes/` — every recipe's task_class.yaml + workflow.yaml
-- `schemas/` — task_class / workflow / artifact_contract schemas
-- `config/providers.yaml`, `config/agents.yaml`
-- `docs/architecture/`, `docs/operator/` — for cross-checking claims
-- `CLAUDE.md` — the canonical context map
-
-## Scope
-
-- Target repo: this repo (mini-ork). ~1 synthesis + 2 anchor lenses.
-- Anchor model lenses: **codex** and **minimax** (as requested). Any other
-  live lenses (glm/kimi) are supplementary coverage only.
-- Depth: exhaustive over `mini_ork/` + `recipes/` + `bin/mini-ork`.
-- Output: read-only doc. No source files under `mini_ork/`, `bin/`,
-  `recipes/`, `schemas/` may be modified.
-
-## Success criteria
-
-- Every lens report exists, is non-empty, and cites ≥1 `file:line` each.
-- The synthesis covers all 7 pillars above with ≥3 features per pillar,
-  each with a code anchor, and a shipped-vs-roadmap marker.
-- The synthesis publishes to `docs/reference/FEATURE-INVENTORY.md`.
-- No feature is asserted without a code anchor (no marketing-only claims).
-
-## Proof of success (verification command)
-
-The run has succeeded when the published inventory exists, is non-trivial,
-covers all seven pillars, and every asserted feature carries a code anchor.
-This command must exit 0:
-
-```bash
-test -s docs/reference/FEATURE-INVENTORY.md \
-  && test "$(wc -l < docs/reference/FEATURE-INVENTORY.md)" -ge 120 \
-  && grep -qi "Orchestration core"        docs/reference/FEATURE-INVENTORY.md \
-  && grep -qi "model dispatch"            docs/reference/FEATURE-INVENTORY.md \
-  && grep -qi "reliability"               docs/reference/FEATURE-INVENTORY.md \
-  && grep -qi "Verification"              docs/reference/FEATURE-INVENTORY.md \
-  && grep -qi "self-improvement"          docs/reference/FEATURE-INVENTORY.md \
-  && grep -qi "Observability"             docs/reference/FEATURE-INVENTORY.md \
-  && grep -qEi "\.py:[0-9]+|:[0-9]+"      docs/reference/FEATURE-INVENTORY.md
-```
-
-## Non-goals
-
-- Do NOT modify any source under `mini_ork/`, `bin/`, `recipes/`,
-  `schemas/` (read-only inventory).
-- Do NOT invent capabilities that aren't in the code; absence of evidence
-  → mark as "not found" rather than assuming it exists.
-- Do NOT audit for bugs/perf/security — this is a capability catalog, not
-  a refactor audit.

-# Propose fixes for the validated GEPA + gradient issues (4-lens panel)
-
-## Problem
-
-A prior 4-lens panel validated a set of issues in mini-ork's self-improvement loop (GEPA +
-the reflection/gradient pipeline). Now each lens must propose **how to fix** the validated
-issues — concrete, implementable, mapped to the real code — from its own angle. This is a
-design panel, not a critique: the output is a fix plan.
-
-**Read both, absolute paths:**
-- Validated issues (panel-1 synthesis): `/Volumes/docker-ssd/ps/mini-ork/docs/_meta/architecture/20260629-findings-validation-panel.md`
-- Original defect report: `/Volumes/docker-ssd/ps/mini-ork/internal-docs/research/2026-07-10-gepa-gradient-issues.md`
-
-**Code to design fixes against (absolute paths):**
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/optimize/gepa.py` and `miniork_adapter.py`
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork-reflect`
-- `/Volumes/docker-ssd/ps/mini-ork/lib/gradient_extractor.sh` and `lib/reflection_pipeline.sh`
-- Existing lifecycle to reuse: `workflow_candidates` → shadow → promote (`bin/mini-ork-improve/eval/promote`, `lib/promotion_gate.sh`).
-
-## The issues to fix (use panel-1's verdicts; skip any it REFUTED)
-
-- **G2** GEPA cannot accept a mutation (offline hash-scoring). Needs an **online evaluator** that can score a *new* prompt, + a real mutation model. This is the unblock-everything fix.
-- **G1/G3/G4** enable path, real model, apply path.
-- **Gr1** runaway re-extraction → a per-trace watermark / high-watermark so a trace is mined once.
-- **Gr2** dedup keyed on trace-specific `signal` → re-key dedup on the *fix* (normalized `suggested_change` per `target`), or semantic (embedding) dedup.
-- **Gr3 / X1** the missing **apply → gate → promote** loop that turns clustered gradients into applied prompt/recipe changes.
-
-## What each lens proposes (fixes from your angle)
-
-- **codex lens (IMPLEMENTATION):** concrete code-level design for each fix — exact functions/files to change, the watermark mechanism, the dedup-normalization function, the online-eval harness for GEPA. Sketch the diff shape and the minimal change set. Prefer reuse over rewrite.
-- **kimi lens (CORRECTNESS):** will each proposed fix actually work? Edge cases, failure modes, why a naive version breaks (e.g. does normalizing the dedup key over-merge distinct fixes? does the watermark drop legitimate re-analysis?). Propose the guardrails.
-- **minimax lens (PERFORMANCE / SEQUENCING):** cheapest-highest-impact ordering. Which fixes are small self-contained bug fixes (Gr1/Gr2) vs larger builds (G2 online-eval, X1 apply loop)? Cost and blast-radius of each. The phased plan.
-- **opus lens (ARCHITECTURE):** design the **apply → online-eval → gate → promote** loop properly (closes G2, G4, Gr3, X1 at once). How gradients/patterns become `workflow_candidates`, how non-regression is enforced, how it stays suggest-safe. The end-state architecture.
-
-## Definition of Done
-
-1. Four lens reports at `${MINI_ORK_RUN_DIR}/lens-*.md`, each proposing concrete fixes for the validated issues from its angle, anchored to real file:line.
-2. A synthesis at `${MINI_ORK_RUN_DIR}/synthesis.md`: a **ranked, sequenced fix plan** — per issue: the recommended fix, the files it touches, effort (S/M/L), risk, and dependencies; consensus-marked where ≥2 lenses agree; disputes reported as disputes. Lead with the smallest changes that stop the bleeding (Gr1/Gr2) and the single unblock-everything change (G2 online-eval).
-3. Publisher writes the synthesis to `docs/_meta/architecture/20260629-findings-validation-panel.md`.
-
-## Scope
-
-Design + proposal only — do NOT implement or edit code. 4 parallel lenses + 1 synthesizer. Budget: $5–15.

-# Validate the GEPA + gradient-pipeline issues (4-lens adversarial panel)
-
-## Problem
-
-We compiled a defect report on why mini-ork's self-improvement (GEPA + the reflection/gradient
-pipeline) has never changed a single prompt in production. We need an **adversarial 4-lens
-validation**: independently confirm or refute each claimed issue with your own evidence, and
-surface any NEW issues the report missed. Do NOT take the report on faith — re-run the queries,
-read the cited code, trace the logic.
-
-**The report under validation (read it fully, absolute path):**

-
-## Issues to validate (label each CONFIRM / REFUTE / PARTIAL with your own evidence)
-
-- **G1** GEPA never enabled (`MO_OPTIMIZER` unset).
-- **G2** GEPA structurally cannot accept a mutation (offline hash-scoring → parent≡child → strict-improvement gate always rejects). *This is the load-bearing claim — scrutinize it hardest.*
-- **G3** Mutation model is `stub`.
-- **G4** Suggest-only; nothing applies (`workflow_candidates=0`).
-- **Gr1** Runaway re-extraction: 9,777 gradients from 1,603 traces; no per-trace watermark; `--since 24h` overlap.
-- **Gr2** Dedup keyed on trace-specific `signal` → cannot collapse semantic duplicates (172 reviewer gradients / 172 distinct).
-- **Gr3** No apply path: 39 `emergent_patterns` all `proposed`.
-- **X1** The whole loop diagnoses but never acts (shared root cause).
-- **X2** Diagnosis quality is high but wasted (the "agents claim without reading/verifying" theme).
-
-## What each lens does (validate the SAME issues from your angle; find new ones)
-
-- **codex lens (ARCHITECTURE / code-truth):** read the actual code paths. Verify the *mechanism* claims — especially G2's `evaluate()` hash-fallback logic and Gr2's dedup key. Trace whether the acceptance gate can ever be satisfied. Cite file:line.
-- **kimi lens (CORRECTNESS / rigor):** re-run the DB queries to confirm the numbers; check the causal logic of each claim; try to falsify. Are any claims overstated or is the true cause different?
-- **minimax lens (PERFORMANCE / systems):** the scale/cost angle — unbounded gradient growth, re-extraction cost, DB bloat, cost of running GEPA/reflect repeatedly, any O(N²) or runaway paths.
-- **opus lens (DEEP / architectural):** the systemic "diagnose-but-never-act" pattern (X1). Are there deeper or additional structural issues? Second-order risks a naive fix would introduce? New issues not in the report.

-uniformly on every node's trace; weight per-node credit toward decisive nodes
-using the existing per-node `process_reward`/verifier signal, falling back to

-# IMPL-1 — Make the gradient pipeline idempotent + dedup effective ("gradients used properly", part 1)
-
-## Goal (one deliverable)
-
-Stop the reflection/gradient pipeline from generating a runaway pile of duplicate gradients, so the
-diagnoses it produces are usable. This is the safe, high-confidence first slice validated by the
-4-lens panel (`docs/_meta/architecture/20260629-findings-validation-panel.md`). It does NOT touch
-GEPA or add an apply path — those are IMPL-2 and IMPL-3.
-
-## Background (validated evidence)
-
-In the researcher DB there are **9,777 gradient rows from only 1,603 traces** (worst trace re-mined
-29×), and `agent.reviewer.prompt` has **172 rows, 0 collapsed** despite ~57 saying the same thing.
-Root causes confirmed by the panel:
-- **Gr1** `extract_gradients` has no per-trace watermark; `reflect --since 24h` overlaps every run, so
-  the same traces are re-mined repeatedly. `__reflect__` traces alone account for ~926 rows.
-- **Gr2** dedup keys on lexical form and, critically, the cross-target pass **skips same-target rows**,
-  so concentrated same-target duplicates (the 172 reviewer rows) are never compared; dedup is also
-  per-`(task_class,target)` so the same insight across task classes never collapses.
-
-## Files in scope (absolute paths)
-
-- `/Volumes/docker-ssd/ps/mini-ork/lib/gradient_extractor.sh` — extraction + `gradient_store` containment dedup.
-- `/Volumes/docker-ssd/ps/mini-ork/lib/reflection_pipeline.sh` — `reflection_deduplicate` (difflib) + `extract_gradients` stage.
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork-reflect` — the `--since` window default.
-
-## Acceptance criteria
-
-1. **Idempotent extraction (Gr1):** `extract_gradients` skips any `trace_id` that already has a
-   gradient in `gradient_records.evidence` (per-trace watermark), so re-running reflect over an
-   overlapping window does not create duplicate gradients. Add a test proving a second reflect over
-   the same window adds 0 new rows.
-2. **Exclude reflect-noise (Gr1):** `__reflect__` (and other framework-internal `__*__`) traces are
-   excluded from gradient extraction. Test: a `__reflect__` trace produces 0 gradients.
-3. **Same-target semantic dedup (Gr2):** the dedup must collapse near-identical gradients that share
-   the same `target` but differ only in trace-specific tokens (numbers, `$costs`, durations,
-   trace-ids, timestamps). Normalize those tokens out of the dedup key, and ensure the same-target
-   case is actually compared (not skipped). Test: 3 reviewer gradients that differ only in
-   "2.7min/$1.62" vs "633s/$3.53" collapse to 1.
-4. **No behavioral regression:** existing reflection_pipeline / gradient_extractor tests still pass;
-   distinct insights (different `suggested_change` intent) are NOT over-merged.
-5. Bash/Python parity preserved where both copies exist.
-
-## Out of scope (do NOT do here)
-
-GEPA changes, the apply→gate→promote loop, cross-`(task_class)` dedup (leave a TODO referencing X1),
-schema migrations beyond what's needed for the watermark.
-
-## Verification
-
-- Unit tests for each acceptance criterion above (idempotent re-run, `__reflect__` exclusion, semantic collapse).
-- A smoke run: extract twice over the same trace window; assert row count stable on the second pass.

-# IMPL-2 — Make GEPA produce real, accepted prompt improvements ("GEPA integrated")
-
-## Goal (one deliverable)
-
-Turn GEPA from an inert scaffold into an optimizer that can actually accept a prompt mutation.
-Two coupled fixes the panel proved must land together (G3 short-circuits before G2 is even reached).
-This does NOT apply the accepted suggestion to production prompts — that is IMPL-3.
-
-## Background (validated by the 4-lens panel)
-
-- **G3** the mutation step dispatches `model="stub"`, an unknown lane that returns `_NoProposal`, so
-  no rewrite is ever proposed. The `stub` default exists in **two** places — both must change:
-  `mini_ork/optimize/gepa.py:148` and `mini_ork/optimize/miniork_adapter.py:311` (`run_suggestion`
-  calls `optimize()` without a model).
-- **G2 (fatal):** the offline adapter's `evaluate()` scores a candidate by matching
-  `candidate['prompt_version_hash']` to cached `reward_value` rows. Seed and mutated candidates have
-  no matching hash → both score `_default_score` → parent ≡ child on every minibatch → the strict
-  gate `sum(new) <= sum(parent)` (`gepa.py:204`) always rejects. **The optimizer can never accept a
-  new prompt because it cannot score a prompt that has never run.**
-
-## Files in scope
-
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/optimize/gepa.py`
-- `/Volumes/docker-ssd/ps/mini-ork/mini_ork/optimize/miniork_adapter.py`
-- `/Volumes/docker-ssd/ps/mini-ork/bin/mini-ork-reflect` (the `MO_OPTIMIZER` enable path)
-
-## Acceptance criteria
-
-1. **Real mutation model (G3):** the mutation step uses a real lane via a new `MO_OPTIMIZER_MODEL`
-   env (default to a reliable code lane, e.g. `minimax`), threaded through `run_suggestion` →
-   `optimize(model=...)` → `reflect_on_component`. No `stub` default reachable in the reflect path.
-2. **Online/held-out evaluator (G2) — the core fix:** add an evaluator that scores a *mutated prompt's
-   text* rather than only looking up a historical hash. Minimum viable: run the candidate prompt on a
-   small held-out set of that task_class's recent inputs and score with the existing rubric/verifier,
-   OR an LLM-judge that compares parent vs mutated output on the reflective examples. The acceptance
-   gate must be able to strictly prefer a genuinely better prompt. Keep the offline hash lookup as a
-   fast path when a hash match exists.
-3. **Provable acceptance:** a test with a deliberately-bad seed prompt and an obviously-better mutation
-   shows `full_eval_count > 0` and the returned best candidate ≠ seed. Today this is impossible.
-4. **Honest validity (new issue from panel):** `validity:"valid"` must distinguish "ran" from
-   "improved" — a run with zero accepted mutations reports `no_improvement`, not `valid`
-   (`miniork_adapter.py` run_suggestion). And `insufficient_evidence` suggestions must not be silently
-   dropped in `bin/mini-ork-reflect:258-260`.
-5. Budget/rollout bound preserved (`full_eval_count <= budget`); suggest-only (no auto-apply here).
-
-## Out of scope
-
-Applying the accepted suggestion to production prompt files (IMPL-3), enabling GEPA by default
-(final switch after IMPL-3), gradient pipeline (IMPL-1).
-
-## Verification
-
-- Unit test: bad-seed → better-mutation is accepted (full_eval_count>0, best≠seed).
-- Unit test: no real improvement → `validity` is `no_improvement`, not `valid`.
-- Smoke: `MO_OPTIMIZER=gepa MO_OPTIMIZER_MODEL=minimax` reflect over a task_class emits a real,
-  non-stub suggestion whose candidate differs from the on-disk prompt.

-# IMPL-3 — Close the apply loop: turn diagnoses into applied prompt changes (X1)
-
-## Goal (one deliverable)
-
-Build the missing **Apply → online-eval → Gate → Promote** stage that the panel identified as the
-load-bearing root cause (X1). This is what finally makes BOTH GEPA suggestions and clustered gradient
-patterns actually change a prompt — the shared piece that "uses gradients properly" and "integrates
-GEPA" for real. Depends on IMPL-2's online evaluator.
-
-## Background (validated)
-
-Today the loop diagnoses and clusters but never acts: `pattern_records(output_type='prompt_change')`,
-`emergent_patterns(status='proposed')` (39 rows), and gradient clusters all sit unconsumed —
-`workflow_candidates`, `promotion_records`, `version_registry`, `textual_gradients` are all empty.
-GEPA (G4) and gradients (Gr3) fail for the same reason: no consumer promotes a proposed change.
-
-## Files / mechanisms in scope
-
-- Reuse the existing lifecycle: `workflow_candidates` → shadow → promote (`bin/mini-ork-improve`,
-  `bin/mini-ork-eval`, `bin/mini-ork-promote`, `lib/promotion_gate.sh`).
-- Consume from: `pattern_records` (GEPA `prompt_change`), `emergent_patterns`/`gradient_records`
-  (clustered prompt gradients).
-- The online evaluator from IMPL-2.
-
-## Acceptance criteria
-
-1. **Apply consumer:** a step (in reflect or a new `bin/mini-ork apply` verb) that takes the
-   highest-confidence proposed prompt change for a `(task_class, target)` and materializes it as a
-   `workflow_candidates` row with the concrete prompt mutation.
-2. **Online-eval gate:** the candidate is scored on a held-out set (reuse IMPL-2's evaluator) vs the
-   current prompt; it is promoted only if it does not regress (non-regression gate) — reuse
-   `promotion_gate` conjunction discipline. Applying WITHOUT a reward comparison is explicitly
-   forbidden (panel: that recreates theater).
-3. **Promotion writes the real prompt + a version:** on promote, the recipe's prompt file is updated
-   and a `version_registry` entry recorded, so the change is auditable and reversible
-   (release-engineering discipline).
-4. **Suggest-safe by default:** the apply step is gated (dry-run / human-approval env) so it never
-   silently rewrites prompts without the gate passing; quarantine on regression.
-5. **End-to-end proof:** a test where a known-good gradient ("reviewer must cite evidence before
-   verdict") flows cluster → candidate → online-eval → promote → the reviewer prompt file now
-   contains the rule, and a regression case is quarantined.
-
-## Out of scope
-
-New diagnosis logic (that already works), cross-repo apply, auto-enabling on every run without the gate.
-
-## Verification
-
-- Unit + integration test of the full cluster → candidate → gate → promote path (happy + regression).
-- Smoke: run apply on the existing `agent.reviewer.prompt` "evidence before verdict" cluster; confirm
-  a candidate is created, evaluated, and either promoted (prompt file changed) or quarantined with a reason.

-# M1: publisher commits in-place code changes on APPROVE (stop silent no-op)
-
-## Problem (observed every dispatch this session)
-`bin/mini-ork-execute` publisher node only knows the artifact-COPY model: read
-`artifact_contract.yaml:outputs[]`, copy `source_artifact` → each output path. For `code-fix`
-(and other in-place-edit recipes) there are no `outputs[]` — the real output is the implementer's
-diff — so the publisher hits `[warn] artifact_contract.yaml has no outputs[] — skipping publish`
-(line ~2616), sets status `published`, and **never commits**. The implementer's edits stay
-uncommitted in the working tree; a human has to `git add`/`commit` them. This is the single biggest
-blocker to the loop running unattended.
-
-## Objective
-On reviewer **APPROVE**, when a recipe has no artifact-copy `outputs[]` but the implementer made
-in-place edits, the publisher should COMMIT those changed files on the current branch — instead of
-skipping. Do not change the artifact-copy path for recipes that DO declare `outputs[]`.
-
-## Deliverables (edit `bin/mini-ork-execute` publisher node)
-1. In the `outputs[]`-empty branch (currently the silent skip), before returning:
-   - Load the implementer's changed-file list from `${RUN_DIR}/implementer-summary.json`
-     (`files_changed` array) if present.
-   - Proceed to commit ONLY when: reviewer verdict is APPROVE (check the run's reviewer verdict /
-     the same signal the publisher already gates on), `files_changed` is non-empty, and each path
-     exists + is inside the target repo (`MO_TARGET_CWD`/git toplevel).
-   - `git -C <target> add -- <each files_changed path>` then `git -C <target> commit` with a message
-     like `mini-ork(<recipe>): <node_desc> [run <run_id>]`. Commit ONLY the files in
-     `files_changed` — never `git add -A` (the 2026-06-13 OSS-leak class). Nothing outside the list.
-   - Set status `published` + log `[publish] committed N file(s): <sha>`.
-   - If verdict is NOT approve, or `files_changed` empty/absent → keep the current skip behavior
-     (log why); do not commit.
-2. Leave the existing artifact-copy publish path (non-empty `outputs[]`) untouched.
-3. Do NOT auto-push or auto-merge to main here (that stays the separate gated auto-merge path). This
-   only commits on the run's working branch.
-
-## Smoke / DoD (must pass)
-- `tests/unit/test_publisher_commit.sh` (source the executor with MINI_ORK_EXECUTE_SOURCE_ONLY=1
-  if the publisher logic is reachable that way, else drive a minimal temp-repo fixture):
-  - Given a temp git repo + a `${RUN_DIR}/implementer-summary.json` listing 1 changed file that
-    exists + a simulated APPROVE + empty outputs[] → publisher creates exactly ONE commit whose
-    changed files == `files_changed` (assert `git show --name-only` matches; assert an UNlisted
-    dirty file is NOT committed).
-  - Given verdict != approve → no commit (skip preserved).
-  - Given a recipe WITH outputs[] → artifact-copy path still runs (existing behavior unchanged).
-- `bash -n bin/mini-ork-execute` clean; existing executor tests (`test_executor_runtime_routing.sh`,
-  `test_scaffold_tier.sh`) + `pytest` still green.
-
-## Constraints (scope guard)
-- Touch ONLY `bin/mini-ork-execute` (publisher node) + the new test. Commit strictly the
-  `files_changed` set, only on APPROVE, only on the working branch — never `git add -A`, never push,
-  never touch main. Default behavior for recipes with `outputs[]` unchanged.

-# Refresh README.md — clean, cohesive, engineer-integration-focused
-
-## Goal
-Rewrite `README.md` so an engineer can understand mini-ork and integrate it into their existing
-agentic-CLI workflow (Claude Code, Codex, Gemini CLI, etc.) in minutes. Trim marketing bloat;
-lead with how it works and how to run it. Keep it cohesive and skimmable.
-
-## Required structure (in this order)
-1. **Title + one-sentence definition + the motto.** Keep the existing motto line. One tight
-   paragraph: mini-ork is a "task operating system for agents" — goal → classify → plan → execute →
-   verify → reflect → improve, dispatched across *distinct model families*, verifier-gated, with
-   persistent learning in `state.db`.
-2. **How it works (short).** The classify→plan→execute→verify→reflect→improve loop in ~6 bullets
-   or a small diagram; the three load-bearing ideas: cross-family review independence, executable
-   (deterministic) verification before LLM opinion, persistent trajectory memory. Link
-   `docs/FEATURES.md` and `docs/ARCHITECTURE.md` for depth. Keep this section tight — no walls of text.
-3. **Quickstart (copy-paste).**
-   - 30-second no-keys demo: `bash examples/00-demo.sh` (dry-run, no LLM calls).
-   - Install: clone + `./install.sh` (or the documented path); note `bin/mini-ork` is the entrypoint.
-   - First real run: `./bin/mini-ork run <recipe> <kickoff.md>` with a concrete tiny example.
-4. **Setup credentials.** Explain `config/secrets.local.sh` (gitignored): the curl-lane keys
-   `GLM_API_KEY` / `KIMI_API_KEY` / `MINIMAX_API_KEY`; that claude/opus/sonnet + codex lanes reuse
-   the local `claude`/`codex` CLIs (no key needed if those CLIs are already authed); and
-   `MINI_ORK_SECRETS` for pointing at a secrets file when vendored into another repo. Show a minimal
-   `secrets.local.sh` template. Mention `./bin/mini-ork doctor` to verify the environment/lanes.
-5. **Integrate into your agentic CLI (Claude Code / Codex / others).** The key new section:
-   - mini-ork dispatches each node to a *lane*; lanes map to model families via `config/agents.yaml`,
-     and providers live in `lib/providers/cl_*.sh` (claude, sonnet, opus, codex, kimi, minimax, glm,
-     deepseek). So it drives your existing `claude` / `codex` / `gemini` CLIs under the hood.
-   - How to vendor mini-ork into an existing repo (its own `.mini-ork/`), point it at that repo, and
-     run recipes against your codebase; note the safe-usage basics (cwd, `MINI_ORK_ROOT`).
-   - How to invoke it from a "master" Claude Code / Codex session (dispatch a recipe, monitor the
-     run, read artifacts) — short, practical.
-6. **Recipes (brief).** What a recipe is (`recipes/<name>/` = workflow.yaml + prompts + verifiers +
-   artifact_contract), how to list them, and 3-4 high-value examples (code-fix, framework-edit,
-   research-synthesis, recursive-self-improve). Link `recipes/`.
-7. **Safety / cost one-liner + links.** Verifier-gated, cross-family, `MO_DAILY_BUDGET_USD` cap,
-   opt-in sandbox backends (`MO_RUNTIME_BACKEND`). Link CONTRIBUTING / docs.
-
-## Hard constraints (must pass the pre-push README claim-check)
-- `scripts/readme-claim-check.sh` MUST still pass. Preserve these EXACT current claim numbers (or
-  update to the true repo counts if you restate them): **lib/*.sh = 88**, **bin/mini-ork-* = 31**,
-  **db/migrations = 47**, **recipes table rows = 28**, **lib/providers/cl_*.sh = 7**. If you keep a
-  "framework primitives" count line, keep it terse and correct. Do NOT introduce any cited path that
-  doesn't exist (the "cited paths exist" probe).
-- All relative links must resolve (the `docs` recipe's link_verifier checks this) — only link files
-  that exist.
-- Keep it substantially SHORTER and cleaner than the current 470 lines where possible without
-  dropping the required sections.
-
-## grep-assert: the refreshed README MUST contain these markers
-`## Quickstart`, `config/secrets.local.sh`, `Claude Code`, `bin/mini-ork run`, `MINI_ORK_RUNTIME`
-or `MO_RUNTIME_BACKEND`, `docs/FEATURES.md`, `./bin/mini-ork doctor`.
-
-## Scope
-Edit ONLY `README.md`. Do not touch code, recipes, or other docs.

-# Close the `classify` integration fork
-
-Status: completed and source-applied on 2026-07-20 from the passing proposal
-produced by `run-1784528328-42404`.
-
-## Goal
-
-Make `mini_ork/ported/mini_ork_classify.py` the sole classify runtime, repoint
-every executable caller away from `bin/mini-ork-classify`, and retire the Bash
-entrypoint as a reviewable proposal. Preserve stdout, exit codes, dry-run
-behavior, DB/trace writes, workflow-version overrides, kickoff size limits,
-and hostile-input handling.
-
-The recipe must edit only the explicit isolated target. It must not edit or
-commit in the source checkout.
-
-## Fork
-
-- **fork:** `classify`
-- **isolated target:** `/private/tmp/mini-ork-self-migrate-classify`
-- **baseline:** `86eba5e7`
-- **python entrypoint:** `/private/tmp/mini-ork-self-migrate-classify/mini_ork/ported/mini_ork_classify.py`
-- **bash entrypoint to retire:** `/private/tmp/mini-ork-self-migrate-classify/bin/mini-ork-classify`
-
-## Preflight evidence
-
-The exact isolated target is clean and passes the live pre-retirement oracle:
-
-- `tests/unit/test_mini_ork_classify_py.py`: 5 passed.
-- `tests/integration/test_bin_classify.sh`: 9 assertions passed.
-- `gates/feature_acceptance.sh classify`: pass.
-- Pyright on classify and the Python CLI: 0 errors.
-
-The recipe's pre-retirement node must capture its own durable green report
-before the Bash entrypoint can be removed. The workflow-phase-aware hollow-run
-guard allows that baseline verifier to run before final artifacts exist; later
-verifiers remain fail-closed.
-
-## Completion evidence
-
-- The run used Kimi for planning, Codex for implementation, and GLM 5.2 for
-  seam mapping, the authoritative ledger, and review. MiniMax was not selected.
-- The durable pre-retirement oracle passed before the Bash entrypoint was
-  removed. Post-retirement parity, feature acceptance, the 29-row ledger, and
-  deterministic fork closure also pass.
-- The proposal deletes `bin/mini-ork-classify`, preserves the classify stdout,
-  exit-code, dry-run, DB, trace, override, size-limit, and hostile-input
-  contracts, and repoints all mapped runtime and test callers to the Python
-  module.
-- The detailed `verdict.json`, GLM reviewer, and run-level workflow verdict
-  pass. The outer command returned non-zero only because the generic Python
-  verifier passed incomplete context to globally registered oracle gates;
-  their `defer` results were aggregated as a failure. No paid replay was used.
-- The reviewed proposal applied cleanly to the source checkout and was replayed
-  with focused unit, integration, security, E2E, Pyright, migration-gate, and
-  diff-hygiene checks.
-
-## Provider policy
-
-Use only these provider values:
-
-- Kimi: planner and broad research.
-- Codex: migrator and coding fallback.
-- GLM 5.2: seam map, authoritative ledger, reviewer, and judgment fallback.
-
-Load Kimi and GLM credentials process-locally from
-`/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`, translating their
-Claude-compatible tokens into the run-local provider variables. Clear gateway
-variables before Codex dispatch. Never persist secret values in the repository,
-runtime configuration, kickoff, or run artifacts. Do not route any role to
-MiniMax or Opus.
-
-Kimi's repository Claude wrapper advertises a stale model name. Use the same
-run-local executable adapter pattern proven by the reflect closure against the
-authenticated Anthropic-compatible messages endpoint.
-
-## Runtime references to resolve
-
-The current executable-tree scan found these literal or dynamic dependencies:
-
-- `bin/mini-ork` — direct subcommand dispatch, user-first probe, and normal run
-  lifecycle classify stage.
-- `bin/mini-ork-validate` — kickoff-to-recipe resolution.
-- `lib/llm-dispatch.sh` — provider/task classification helper.
-- `mini_ork/ported/mini_ork_cli.py` — two dynamic `_bin(root, "classify")`
-  subprocess calls.
-- `mini_ork/web/routes/run_detail.py` — web run-detail classify invocation.
-- `tests/e2e/test_e2e_recipe_bdd_first.sh`
-- `tests/e2e/test_e2e_recipe_code_fix.sh`
-- `tests/e2e/test_e2e_trace_lifecycle.sh`
-- `tests/integration/test_bin_classify.sh`
-- `tests/security/test_sec_env_var_pollution.sh`
-- `tests/security/test_sec_hooks_attack_surface.sh`
-- `tests/security/test_sec_kickoff_command_injection.sh`
-- `tests/security/test_sec_kickoff_path_traversal.sh`
-- `tests/security/test_sec_malformed_yaml.sh`
-- `tests/security/test_sec_oversized_input.sh`
-- `tests/security/test_sec_sql_injection_run_id.sh`
-- `tests/unit/test_mini_ork_classify_py.py`
-
-Also update current public documentation and Python module descriptions that
-still identify the deleted Bash file as the runtime. Historical audits and
-plans may retain path mentions when they clearly describe past state; runtime
-closure is enforced only across executable trees.
-
-## Required implementation contracts
-
-1. Replace every executable call to `bin/mini-ork-classify` with the Python
-   module using an explicit `PYTHONPATH`/module environment rooted at the target.
-2. Preserve stdout exactly where callers parse `task_class=...` and
-   `workflow_version=...`; do not introduce logging on stdout.
-3. Preserve dry-run as side-effect free and retain non-dry DB/trace writes,
-   explicit task-class override, workflow-version override, missing-file exit
-   behavior, and `MO_MAX_KICKOFF_BYTES` enforcement.
-4. Convert the unit suite from a live Bash oracle to standalone golden and
-   behavioral contracts only after the durable pre-retirement report is green.
-5. Keep integration, E2E, web-route, validation, and security coverage attached
-   to the Python-sole entrypoint; do not delete tests merely because the Bash
-   path is gone.
-6. Delete `bin/mini-ork-classify` only after all callers and tests are repointed.
-
-## Acceptance criteria
-
-- `verifiers/pre-retirement-parity.sh` records the green five-test Bash/Python
-  oracle before retirement.
-- `verifiers/parity.sh` validates the post-retirement classify contract.
-- `verifiers/feature-acceptance.sh` runs classify feature acceptance, the unit
-  contracts, integration coverage, relevant security coverage, and Pyright on
-  classify plus changed Python callers.
-- `verifiers/ledger-shape.sh` classifies every behavior in
-  `mini_ork_classify.py`; every agentic row includes a concrete cost or
-  verifiability opportunity.
-- `verifiers/fork-closure.sh` confirms `bin/mini-ork-classify` is absent and no
-  literal or dynamic runtime reference survives in executable trees.
-- Reviewer inputs include all five reports, the diff, integration map, ledger,
-  and detailed verdict. The detailed `verdict.json` says `"pass": true` before
-  promotion.
-- The source checkout receives only the reviewed, passing proposal and focused
-  migration-documentation updates.

-the Bash implementation at `bin/mini-ork` with a thin Python launcher. Preserve
-the installed command path, user-facing CLI contract, run lifecycle, and every
-already-closed Python fork. Repoint every runtime caller and retire the Bash
-dispatcher implementation as one reviewable migration diff.
-
-## Fork
-
-- **fork:** `cli`
-- **isolated target:** `/private/tmp/mini-ork-self-migrate-cli`
-- **python implementation:** `/private/tmp/mini-ork-self-migrate-cli/mini_ork/ported/mini_ork_cli.py`
-- **Bash implementation to retire:** `/private/tmp/mini-ork-self-migrate-cli/bin/mini-ork`
-- **public launcher path to preserve:** `/private/tmp/mini-ork-self-migrate-cli/bin/mini-ork`
-
-Unlike command forks named `bin/mini-ork-<fork>`, CLI closure must not remove
-the public `bin/mini-ork` path. It must replace that file with a Python launcher
-whose shebang and runtime contain no Bash delegation.
-
-## Pre-retirement evidence
-
-- The initial 6-test helper could delegate back to Python because it did not
-  force `MINI_ORK_RUNTIME=bash`; it is retained only as historical preflight.
-- Corrected explicit-Bash evidence: the untouched pushed-main dispatcher passed
-  40 assertions, and exact version/help/doctor/error parity passed against the
-  new Python launcher.
-- `python3 -m pyright mini_ork/ported/mini_ork_cli.py`: 0 errors.
-- `pre-retirement-parity.sh` recorded a passing CLI oracle under
-  `/private/tmp/mini-ork-cli-preflight`.
-- Corrected durable evidence is stored under the paid run as
-  `true-bash-parity-evidence.log`.
-
-## Outbound seams to close or preserve explicitly
-
-- Direct dispatch for already-closed `classify`, `plan`, `verify`, and
-  `reflect` forks must invoke their Python modules, never deleted Bash paths.
-- The run lifecycle must continue to call the native classify, plan, verify,
-  and reflect modules and preserve execute as the one remaining Bash command
-  fork until the execute migration closes.
-- `_deadline`, repo-integrity, run-config snapshot, and rubric pre-screen shell
-  calls are library seams below the CLI frontier. Keep their observable
-  contracts explicit; do not silently drop them during dispatcher retirement.
-- Generic subcommand dispatch may retain live `bin/mini-ork-<sub>` commands,
-  but it must never recreate references to already-retired entrypoints.
-
-## Inbound references to resolve
-
-- `install.sh` and packaging/install tests that install or symlink
-  `bin/mini-ork`.
-- `.github/workflows/ci.yml` CLI initialization calls.
-- `mini_ork/scheduler.py`, `mini_ork/ported/mini_ork_scheduler.py`,
-  `mini_ork/web/control.py`, and `mini_ork/web/routes/dispatch.py`.
-- `lib/sandbox/local.sh`, `bin/mini-ork-spawn`, `bin/mini-ork-scheduler`,
-  `bin/mini-ork-self-improve`, and research/learning scripts that launch a run.
-- CLI unit, dispatcher integration, security, E2E, live, and web tests that
-  execute or inspect the public launcher.
-- `lib/runtime-select.sh`, `scripts/runtime-parity-harness.sh`, and all
-  self-migrate verifiers must understand CLI's preserved Python launcher.
-
-Historical documentation may retain literal command examples such as
-`bin/mini-ork run`; those are public CLI usage, not references to a Bash
-implementation. Runtime closure is defined by interpreter/runtime behavior,
-not removal of the public command string.
-
-## Acceptance criteria
-
-- Durable pre-retirement parity remains available after the Bash body is gone.
-- `bin/mini-ork` exists, is executable, and launches the Python CLI without
-  sourcing Bash or consulting `MINI_ORK_RUNTIME`.
-- Direct `classify`, `plan`, `verify`, and `reflect` dispatch reaches the native
-  Python modules; `execute` remains a live command fork until its own closure.
-- Help, version, doctor, unknown-command, deadline validation, explicit recipe,
-  inferred recipe, strict profile, and dry-run lifecycle behavior remain green.
-- `tests/unit/test_mini_ork_cli_py.py` becomes a standalone Python contract and
-  no longer reads/extracts the retired Bash implementation.
-- CLI feature acceptance, focused Pyright, static-feature ledger, and the
-  CLI-specialized fork-closure gate all pass.
-- No provider credential value, run artifact, temporary adapter, or user-owned
-  `.mini-ork/config/agents.yaml` change enters the diff.

-# Close the `execute` integration fork
-
-Status: completed on 2026-07-20; ready for clean-main promotion.
-
-## Goal
-
-Make `mini_ork/ported/mini_ork_execute.py` the sole executor implementation,
-route the top-level Python CLI to it in-process, repoint every executable
-caller, and retire `bin/mini-ork-execute`. Preserve the complete node lifecycle,
-provider routing, verification, learning, publisher, rollback, checkpoint,
-telemetry, concurrency, and failure contracts as one reviewable migration.
-
-## Fork
-
-- **fork:** `execute`
-- **python implementation:** `mini_ork/ported/mini_ork_execute.py`
-- **Bash entrypoint retired:** `bin/mini-ork-execute`
-
-## Required true-Bash oracle
-
-The pre-retirement oracle must execute the untouched Bash implementation with
-`MINI_ORK_RUNTIME=bash`. Do not accept evidence that reaches Python through
-`lib/runtime-select.sh`, and do not treat helper extraction alone as proof of
-the public executor contract. Preserve the durable oracle evidence after the
-Bash entrypoint is deleted.
-
-## Outbound seams to close
-
-The Python executor must use native Python ports for every Bash-owned library
-bridge in its live orchestration path:
-
-- `lib/llm-dispatch.sh` -> `mini_ork.ported.llm_dispatch`
-- `lib/lane-helpers.sh` capability checks -> `mini_ork.ported.lane_helpers`
-- `lib/context_assembler.sh` learned failure modes and operator steering ->
-  native context modules; preserve opt-out, empty-result, and best-effort rules
-- `lib/intervention_gate.sh` -> a native Python gate with the same proceed/block
-  return contract
-
-Executable verifier references may remain scripts because recipe verifiers are
-user-defined executable contracts, not an implementation fallback. Git and
-provider subprocesses may remain where they are the external boundary. Any
-other sourced Bash library found in the live executor path must be classified
-and either ported or justified as an external executable contract.
-
-## Inbound references to resolve
-
-- `mini_ork/ported/mini_ork_cli.py`: remove `execute` from `_EXEC_SUBS`, route
-  direct execute and the run lifecycle to `mini_ork_execute.main` in-process,
-  and preserve captured stdout/stderr plus exit status.
-- `lib/runtime-select.sh` and `scripts/runtime-parity-harness.sh`: remove the
-  retired execute fallback and replace historical parity with a standalone
-  Python/golden contract after durable Bash evidence is captured.
-- Source-based learning and smoke scripts (`learning-loop-live-validate.sh`,
-  `rlm-shared-brain-smoke.sh`, `smoke-learning-loops.sh`) must import or call
-  native Python helpers rather than source the deleted entrypoint.
-- Integration, unit, E2E, performance, observability, security, scheduler,
-  web, gate, and recipe verifier callers discovered by the seam map must use
-  `python3 -m mini_ork.ported.mini_ork_execute`, the public `mini-ork execute`
-  route, or direct native helpers as appropriate.
-- Comments and current operator/migration docs must not describe the retired
-  Bash executor as live. Historical evidence may name it when clearly marked.
-
-## Acceptance criteria
-
-- A durable, explicit-`MINI_ORK_RUNTIME=bash` pre-retirement oracle is green.
-- `bin/mini-ork-execute` is physically absent.
-- `python3 -m mini_ork.ported.mini_ork_execute --help`, missing-plan errors,
-  dry-run, node filtering, dispatch-mode overrides, and unknown flags preserve
-  the public observable contract.
-- Direct `mini-ork execute` and the full `mini-ork run` lifecycle call the
-  native executor without resolving a sibling Bash entrypoint.
-- No executable/runtime reference to `bin/mini-ork-execute`, dynamic
-  `_bin(..., "execute")`, or `source ... mini-ork-execute` survives.
-- Native dispatch, context, capability, intervention, verification, learning,
-  publisher, rollback, checkpoint, telemetry, and bounded-parallel contracts
-  have focused tests.
-- Execute feature acceptance, focused Pyright, the static-feature ledger, and
-  deterministic fork closure all pass.
-- No credential value, provider adapter, temporary home, run artifact, local
-  state database, or user-owned `.mini-ork/config/agents.yaml` enters a commit.
-
-## Verification commands

-
-- Kimi: planner and broad discovery.
-- Codex: migrator/implementer.
-- GLM 5.2: seam map, static-feature ledger, and reviewer.
-- MiniMax and DeepSeek are forbidden.
-- Kimi and GLM credentials were loaded process-locally from the user's local
-  `~/ps/scripts` wrappers; no credential value or adapter was persisted.
-- The one authorized paid execute migration run was consumed. Its GLM review
-  returned `needs_revision`; deterministic completion fixed the reported PRM
-  and minimal-scaffold gaps without a paid retry.
-
-## Files in scope
-
-- `mini_ork/ported/mini_ork_execute.py`
-- `mini_ork/ported/mini_ork_cli.py`
-- `bin/mini-ork-execute` (delete)
-- Native modules needed to close the four outbound Bash-library seams
-- Tests and scripts that execute or source the retired entrypoint
-- `lib/runtime-select.sh`, `scripts/runtime-parity-harness.sh`,
-  `gates/feature_acceptance.sh`, and self-migrate verifiers
-- Current execute/operator/migration documentation and completion-audit files
-
-The seam mapper must expand this list from the repository. A file is in scope
-only when it closes an execute runtime edge, preserves its observable contract,
-or records migration evidence; unrelated cleanup is forbidden.
-
-## Completion evidence
-
-- The true-Bash pre-retirement oracle is preserved and all five self-migrate
-  gates pass against the final diff.
-- The focused executor suite passes 57 tests; the native dispatcher suite
-  passes 11 tests; the adjacent native-port/CLI suite passes 88 tests; and
-  focused Pyright reports zero errors.
-- Execute integration, E2E, recursive, telemetry, performance, and isolated
-  observability checks pass. The duration probe confirms a real provider-free
-  dispatch persists a non-zero trace duration under the plan's task class.
-- `bin/mini-ork-execute` is absent, the public CLI routes execute in-process,
-  and no executable inbound edge references the retired path.

-# Close the `plan` integration fork
-
-Status: completed on 2026-07-20; merged to `main` after two completion audits.
-
-Run `run-1784532524-76798` produced a partial proposal and correctly retained
-the Bash entrypoint after finding four unmapped contracts. The completion audit
-ported those profile, context, context-pack, and trace contracts natively,
-passed the five migration gates, and retired `bin/mini-ork-plan` without a paid
-retry. See `docs/migration/remaining-migration-handoff.md` for the evidence.
-
-## Goal
-
-Make `mini_ork/ported/mini_ork_plan.py` the sole plan runtime, replace its
-remaining Bash `llm-dispatch.sh` subprocess with the native Python dispatcher,
-repoint every executable caller away from `bin/mini-ork-plan`, and retire the
-Bash entrypoint as a reviewable proposal. Preserve stdout, stderr, exit codes,
-dry-run behavior, schema validation, repair limits, profile gates, given-plan
-behavior, DB/trace writes, output paths, and provider/cost telemetry.
-
-The recipe must edit only the explicit isolated target. It must not edit or
-commit in the source checkout.
-
-## Fork
-
-- **fork:** `plan`
-- **isolated target:** `/private/tmp/mini-ork-self-migrate-plan`
-- **baseline:** `928db915`
-- **python entrypoint:** `/private/tmp/mini-ork-self-migrate-plan/mini_ork/ported/mini_ork_plan.py`
-- **bash entrypoint to retire:** `/private/tmp/mini-ork-self-migrate-plan/bin/mini-ork-plan`
-
-## Preflight evidence
-
-The exact isolated target is clean and has this no-cost baseline:
-
-- `tests/unit/test_mini_ork_plan_py.py`: 9 passed.
-- `tests/integration/test_bin_plan.sh`: 10 assertions passed.
-- `tests/integration/test_given_plan.sh`: 7 assertions passed.
-- `gates/feature_acceptance.sh plan`: pass.
-- Focused Pyright currently reports three baseline errors in
-  `mini_ork/ported/mini_ork_plan.py` at the float conversion near line 419 and
-  the optional dispatch call near line 569. The migration must leave focused
-  Pyright clean; do not waive or hide these errors.
-
-The recipe's pre-retirement node must capture its own durable green report
-before the Bash entrypoint can be removed. The workflow-phase-aware hollow-run
-guard allows that baseline verifier to run before final artifacts exist; later
-verifiers remain fail-closed.
-
-## Provider policy
-
-Use only these provider values:
-
-- Kimi: planner and broad research.
-- Codex: migrator and coding fallback.
-- GLM 5.2: seam map, authoritative ledger, reviewer, and judgment fallback.
-
-Load Kimi and GLM credentials process-locally from
-`/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`, translating their
-Claude-compatible tokens into the run-local provider variables. Clear gateway
-variables before Codex dispatch. Never persist secret values in the repository,
-runtime configuration, kickoff, or run artifacts. Do not route any role to
-MiniMax or Opus.
-
-Kimi's repository Claude wrapper advertises a stale model name. Use the same
-run-local executable adapter pattern proven by the reflect and classify
-closures against the authenticated Anthropic-compatible messages endpoint.
-
-## Outbound seam to close first
-
-`mini_ork/ported/mini_ork_plan.py::_default_llm_dispatch` currently executes
-`bash -c`, sources `lib/llm-dispatch.sh`, and calls the Bash `llm_dispatch`
-function. This makes the Python port non-native and blocks Bash retirement.
-
-Replace that subprocess with the existing native
-`mini_ork.ported.llm_dispatch.llm_dispatch` API. Preserve the injectable
-`dispatch(task_class, node_type, prompt) -> (returncode, combined_output)`
-contract by capturing native stdout and stderr into the same buffer. Preserve
-provider selection, retry/fuse behavior, cost and duration sidecars,
-`llm_calls` telemetry, protocol-block stripping, and failure return codes.
-
-## Runtime references to resolve
-
-The current executable-tree scan found these literal or dynamic dependencies:
-
-- `bin/mini-ork` — direct subcommand dispatch and normal run lifecycle plan
-  stage.
-- `mini_ork/ported/mini_ork_cli.py` — `_EXEC_SUBS` direct dispatch and dynamic
-  `_bin(root, "plan")` lifecycle call.
-- `scripts/runtime-parity-harness.sh` — direct Bash plan parity calls.
-- `tests/unit/test_mini_ork_plan_py.py` — live Bash parity oracle.
-- `tests/integration/test_bin_plan.sh`
-- `tests/integration/test_given_plan.sh`
-- `tests/e2e/test_e2e_recipe_bdd_first.sh`
-- `tests/e2e/test_e2e_recipe_code_fix.sh`
-- `tests/security/test_sec_hooks_attack_surface.sh`
-- `tests/security/test_sec_kickoff_command_injection.sh`
-- `tests/security/test_sec_oversized_input.sh`
-- `tests/test_web_smoke.py` — reads the Bash source directly.
-
-Also refresh current runtime descriptions in `bin/mini-ork-execute`,
-`mini_ork/ported/mini_ork_execute.py`, `bin/mini-ork-self-improve`,
-`lib/llm-dispatch.sh`, `lib/context_assembler.sh`,
-`lib/active_state_index.sh`, `lib/extract_verdict.py`,
-`mini_ork/web/routes/run_detail.py`, and
-`scripts/slm_plan_or_fallback.sh`. Historical audits and plans may retain path
-mentions when they clearly describe past state.
-
-## Required implementation contracts
-
-1. Make the Python planner runtime-native before deleting the Bash entrypoint.
-2. Replace every executable call to `bin/mini-ork-plan` with the Python module
-   using an explicit `PYTHONPATH`/module environment rooted at the target.
-3. Preserve the planner dispatch callable's combined output and return-code
-   contract while using the native Python LLM dispatcher.
-4. Preserve plan JSON normalization, verifier-contract enforcement, repair
-   exhaustion, deterministic fallback opt-in, profile blocking, dry-run,
-   `MO_GIVEN_PLAN`, explicit task-class/output flags, DB writes, trace writes,
-   and stdout/stderr discipline.
-5. Convert the unit suite from a live Bash oracle to standalone golden and
-   behavioral contracts only after the durable pre-retirement report is green.
-6. Keep integration, E2E, security, web, and runtime-parity coverage attached
-   to the Python-sole entrypoint; do not delete tests because Bash is gone.
-7. Resolve the three focused Pyright errors and delete `bin/mini-ork-plan` only
-   after all callers and tests are repointed.
-
-## Acceptance criteria
-
-- `verifiers/pre-retirement-parity.sh` records the green Bash/Python oracle
-  before retirement.
-- `verifiers/parity.sh` validates the post-retirement standalone plan contract.
-- `verifiers/feature-acceptance.sh` runs plan feature acceptance, unit,
-  integration, given-plan, relevant security, and focused Pyright coverage.
-- `verifiers/ledger-shape.sh` classifies every behavior in
-  `mini_ork_plan.py`; every agentic row includes a concrete cost or
-  verifiability opportunity.
-- `verifiers/fork-closure.sh` confirms `bin/mini-ork-plan` is absent and no
-  literal or dynamic runtime reference survives in executable trees.
-- Reviewer inputs include all five reports, the diff, integration map, ledger,
-  and detailed verdict. The detailed `verdict.json` says `"pass": true` before
-  promotion.
-- The source checkout receives only the reviewed, passing proposal and focused
-  migration-documentation updates.

-# Audit and close ownership of `mini_ork/ported/` recursively
-
-## Mode
-
-Start with a **report-only inventory**. Do not edit, delete, commit, merge, or
-push source code in the first run.
-
-The governing plan is
-`docs/migration/ported-module-ownership-recursive-plan.md`. Follow its safety
-invariants, classifications, per-module contract, provider policy, artifacts,
-and completion conditions exactly.
-
-## Goal
-
-Produce a complete evidence-backed inventory of every
-`mini_ork/ported/*.py` module, then propose the first bounded ownership unit.
-The first candidate is `similarity.py`: confirm whether its pure algorithm is
-duplicated in `mini_ork/context_assembler.py` and whether integration is the
-correct terminal decision.
-
-## Required discovery
-
-- Read current migration and architecture documents.
-- Reconstruct Git introduction, port, adoption, and retirement history.
-- Retrieve relevant ContextNest sessions and decisions.
-- Map static and dynamic runtime callers, duplicate implementations, tests,
-  integration/E2E/security coverage, benchmark references, and fixtures.
-- Distinguish intentional external-process adapters from accidental Bash
-  dependencies.
-
-## Required artifacts
-
-Write to the run directory only:
-
-- `ported-module-inventory.json`
-- `history-intent.md`
-- `ownership-map.json`
-- `proposed-queue.json`
-- `verdict.json`
-
-Every module must be classified as `active`, `duplicated`, `dormant`, `dead`,
-or `external_adapter`, with a proposed decision of `integrate`, `retain`,
-`delete`, or `defer`. Every decision must cite concrete evidence and name an
-owner or target consumer.
-
-## Provider policy
-
-- Kimi: discovery and history synthesis.
-- GLM 5.2: classification and independent review.
-- Codex: no implementation in this report-only run; reserve it for the bounded
-  source-change unit after approval.
-- Deterministic scripts: reference, fixture, schema, and completeness gates.
-
-Load Kimi and GLM credentials process-locally from
-`/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh` using a temporary
-`MINI_ORK_HOME`. Never persist secrets. Do not use MiniMax, DeepSeek, or Opus,
-and do not permit implicit fallback to them.
-
-## Report-only acceptance criteria
-
-- Inventory row count equals the current `mini_ork/ported/*.py` file count.
-- Every row contains runtime, duplicate, test, benchmark/fixture, docs/history,
-  classification, decision, owner, confidence, and risk fields.
-- Every `delete` proposal proves all deletion gates from the governing plan.
-- Every `integrate` proposal names the canonical target and consumer.
-- Every external adapter states why the process boundary is intentional.
-- The proposed queue respects dependency order and contains one ownership seam
-  per unit.
-- `similarity.py` has a complete contract proposal covering threshold, source
-  tables, top-three selection, citations, suggested fixes, ordering, rounding,
-  and missing-table behavior.
-- `verdict.json` fails closed when evidence is missing.
-
-## Stop condition
-
-Stop after emitting the reviewed inventory and first-unit proposal. Source
-implementation begins only in a new isolated worktree and a separately
-reviewable migration commit.

-run produces a new failure. The recipe's `pre-retirement-parity` node remains
-fail-closed and must preserve its own durable green report before migration.
-
-### Provider preflight
-
-The first paid launch (`run-1784502357-9667`) stopped before planning because
-the frozen operator policy routes `planner` and `glm_lens` to MiniMax while
-`MINIMAX_API_KEY` is unavailable. The isolated target remained clean.
-
-The retry uses the dedicated runtime home
-`/private/tmp/mini-ork-self-migrate-reflect-home`. Its frozen policy contains
-only three provider values:
-
-- Kimi: planner and general research
-- Codex: migrator and coding fallback
-- GLM: seam mapper, authoritative ledger, reviewer, and judgment fallback
-
-Load the Kimi and GLM credentials process-locally from
-`/Users/admin/ps/scripts/cl_kimi.sh` and `cl_glm.sh`, translate their
-Claude-compatible tokens into `KIMI_API_KEY` and `GLM_API_KEY`, then clear the
-temporary Anthropic gateway variables before launching. Never copy secret
-values into this kickoff, the runtime home, or run artifacts.
-
-The successful run used GLM model `glm-5.2`. Kimi's authenticated catalog
-exposed `kimi-for-coding`, while the repository Claude wrapper's hard-coded
-model was rejected; a mode-700 run-local executable adapter called the
-Anthropic-compatible messages endpoint directly. No credentials were persisted.
-
-## Inbound references to resolve
-
-- `bin/mini-ork` — repoint direct and automatic run-lifecycle reflection.
-- `bin/mini-ork-execute` — repoint the legacy executor's automatic reflection.
-- `mini_ork/ported/mini_ork_execute.py` — replace its direct Bash subprocess.
-- `mini_ork/ported/mini_ork_cli.py` — replace dynamic `_bin(root, "reflect")`
-  dispatch with the native module.
-- `tests/test_gepa_wiring_py.py` — remove direct dependence on the Bash CLI.
-- `tests/integration/test_bin_reflect.sh` — convert integration coverage to the
-  Python-sole entrypoint contract.
-- `tests/unit/test_mini_ork_reflect_py.py` — preserve pre-retirement parity
-  evidence, then convert the suite to Python golden/behavioral contracts.
-- `scripts/runtime-parity-harness.sh` — add a focused post-retirement `reflect`
-  contract if the global harness cannot run without the removed Bash oracle.
-- `gates/feature_acceptance.sh` — retain the Python-sole reflect probe.
-
-The deterministic closure gate also searches executable/runtime trees. Update
-the following stale path references without changing their behavior:
-
-- `bin/mini-ork-bug-collector`
-- `lib/reflection_pipeline.sh`
-- `mini_ork/ported/mini_ork_bug_collector.py`
-- `mini_ork/optimize/gepa.py`
-- `mini_ork/ported/mini_ork_reflect.py`
-- `recipes/audit-findings-validator/verifiers/missing-impl.sh` — replace its
-  Bash-file implementation check with a Python-port capability check. The seam
-  map proved this path is a phantom edge in the isolated target, so no file was
-  created or changed.
-
-## Acceptance criteria
-
-- `verifiers/pre-retirement-parity.sh` captures a green, durable Bash/Python
-  parity report before the Bash entrypoint can be deleted.
-- `verifiers/parity.sh` validates the post-change reflect contract.
-- `verifiers/feature-acceptance.sh` passes `gates/feature_acceptance.sh reflect`,
-  the reflect unit suite, integration coverage, and Pyright on the port.
-- `verifiers/ledger-shape.sh` classifies every behavior in
-  `mini_ork_reflect.py`; each agentic row has a concrete cost/verifiability
-  opportunity.
-- `verifiers/fork-closure.sh` confirms `bin/mini-ork-reflect` is absent and no
-  literal or dynamic runtime reference survives.
-- The run mirror is harvested before review, the reviewer receives all five
-  recipe reports plus the diff/map/ledger/detailed verdict, and generic status
-  remains in `run-verdict.json`.
-- The detailed `verdict.json` says `"pass": true` before any proposal is
-  promoted to the source branch.
-

-# Epic — Sandbox P2: per-agent Docker environments + shared drive
-
-**Status:** IN PROGRESS (opened 2026-07-31)
-**Owner:** Amir + Claude
-**Roadmap:** cloud-exec sandbox A1 → P2 (first *real* cross-environment backend).
-**Design context:** `internal-docs/research/2026-07-30-sandbox-shared-drive-design.md`
-(gitignored); prior phases `kickoffs/sandbox-p0-workspace-protocol.md`,
-`mini_ork/runtime/{sandbox,shared_drive,run_drive}.py` (P0/P1a/P1b, on main).
-
----
-
-## Why (the user ask, verbatim intent)
-
-> Run mini-ork as the **main brain** on the host, spawning each agent in a
-> **different environment**, with all agents able to read/write a **shared set
-> of directories** accessible to every agent in the run.
-
-Today (verified 2026-07-31, post-reconcile at merge `555f788b`):
-- **Brain spawning agents** — already works (executor + dispatch).
-- **Shared directory** — works *on one host only*, opt-in via `local-bind`
-  (`MO_SHARED_DRIVE_BACKEND=local-bind`), and only the implementer cwd is
-  routed (`mini_ork/cli/execute.py:2251`).
-- **Each agent in a different env** — **does NOT work.** There is exactly one
-  environment: the host. `get_workspace`/`Workspace.exec` has **zero callers**
-  outside `sandbox.py`; only the `local` backend is registered; agents run as
-  host subprocesses. The `Workspace` protocol (P0) is the seam, unused.
-
-This epic delivers the first backend that puts **each agent in its own Docker
-container** while every container **bind-mounts the same shared drive**, so the
-user's ask is satisfied on a single machine with **no cloud credentials**
-(Docker 29.2.1 via colima is present). Cross-*machine* (cloud Volumes) remains
-a later phase (P3/P4) and is explicitly out of scope here.
-
-## Non-goals (protect scope)
-- No cloud provider backends (e2b/modal/daytona) — P3+.
-- No microVM/gVisor — Docker first, harden later.
-- No change to default behavior: everything below is **opt-in** and a **no-op**
-  unless `MO_SANDBOX_BACKEND` is set. `MO_SANDBOX_BACKEND=local` (default) =
-  byte-for-byte today's host execution.
-- No new orchestration model — reuse `Workspace`/`SharedDrive` protocols and the
-  registry seams already shipped.
-
----
-
-## Design — three pieces (each a sub-phase)
-
-### Piece 1 — `DockerWorkspace` backend  (`Workspace` impl)
-A backend registered as `docker` satisfying the existing `Workspace` protocol
-(`sandbox.py`): 
-- `up()` → `docker run -d` a long-lived container from `MO_SANDBOX_IMAGE`,
-  bind-mounting the run's shared-drive host dir at a fixed in-container path
-  (`/workspace`), passing through provider env (API keys / gateway base_urls),
-  cpu/memory limits from `MO_SANDBOX_CPU`/`_MEMORY`. Container name is
-  run+node scoped so parallel agents get distinct containers.
-- `exec(cmd, *, cwd, timeout)` → `docker exec -w <cwd> <cid> sh -lc <cmd>`,
-  merged stdout+stderr, returncode; timeout kills via `docker exec` wrapper +
-  `docker stop`. Mirror `mo_runtime_exec`'s `(rc, output)` return.
-- `put(content)` / `get(path)` → `docker cp` (or `exec sh -c 'cat > …'`).
-- `down()` → `docker rm -f <cid>`. Container = **cattle** (safe to destroy);
-  the drive = **pet** (never destroyed here — that's `SharedDrive.down`).
-- Register via `register_workspace_backend("docker", …)` at import of a new
-  `mini_ork/runtime/backends/docker.py` (keep `sandbox.py` dependency-free;
-  the docker backend imports only stdlib `subprocess`/`shutil`, no docker SDK —
-  shell out to the `docker` CLI so there is no new pip dependency).
-
-**Acceptance (P1):**
-1. `mini_ork/runtime/backends/docker.py` defines `DockerWorkspace` + registers
-   `docker`. `get_workspace("docker", image=…, drive_root=…, mount_path="/workspace")`
-   returns a live instance; `get_workspace("docker")` with no daemon raises a
-   clear `RuntimeError` (not a traceback).
-2. Round-trip test (skipped when `docker` absent): `up()` →
-   `put`/`get` a file on the mounted drive → `exec("echo hi", cwd="/workspace")`
-   returns `(0, "hi\n")` → a file written by `exec` is visible on the host drive
-   dir (proves the bind mount) → `down()` removes the container.
-3. `exec` timeout kills a runaway (`sleep 999`, timeout=2 → non-zero, container
-   still healthy or torn down; no host hang).
-4. Nothing in the default path imports this module; adding it changes no
-   existing test.
-
-### Piece 2 — route agent execution through the `Workspace` seam (opt-in)
-Wire the two execution seams so that, when `MO_SANDBOX_BACKEND` is set, the
-agent runs **inside the workspace** instead of a host subprocess:
-- **Agent tool-exec:** `mini_ork/agent/minimal.py` currently calls
-  `mo_runtime_exec` directly. Route through `get_workspace(backend).exec(...)`
-  (the `local` backend already delegates to `mo_runtime_exec`, so `local` is a
-  no-op refactor; `docker` sends the tool command into the container).
-- **Provider transport:** the coding-agent CLI launch
-  (`dispatch/core.py:58`, `dispatch/lane_helpers.py`, `dispatch/codex_transport.py:403`)
-  is the *stronger* isolation point — run the whole agent CLI in the container.
-  This is riskier (needs the agent binary + keys + network egress inside the
-  image). Gate it behind `MO_SANDBOX_SCOPE=tool|agent` (default `tool` = only
-  route tool-exec; `agent` = route the CLI too). Ship `tool` first.
-- The run provisions ONE `SharedDrive` (P1a) and passes its `mount_path` to each
-  `DockerWorkspace` as the bind source, so every agent's container sees the same
-  `/workspace`. Reuse `resolve_run_drive_cwd`; the cwd handed to `exec` is the
-  in-container mount path, not the host path.
-
-**Acceptance (P2):**
-1. `MO_SANDBOX_BACKEND` unset → identical behavior + identical test output as
-   today (dead-code proof, like P1b: full green gate unchanged).
-2. `MO_SANDBOX_BACKEND=local` → agent tool-exec routes through `LocalWorkspace`
-   with no observable change (parity test).
-3. `MO_SANDBOX_BACKEND=docker MO_SANDBOX_SCOPE=tool` on a toy 2-node run →
-   each node's shell tool runs in a container; a file one node writes to
-   `/workspace/shared.txt` is read by the next node (proves cross-agent shared
-   dir across **distinct environments**). Concurrency still guarded by CAID
-   `--owns`.
-4. Loud failure: unknown backend / dead daemon → `ValueError`/`RuntimeError`
-   surfaced, never a silent host fallback.
-
-### Piece 3 — verifier / ranking hooks (defer, tracked only)
-Behavioral verification of the sandbox (does the agent's container actually
-produce the artifact?) belongs to the **behavioral-verify** epic
-(`wt/behavioral-verify-p0`). Cross-link only; not built here.
-

-## Env surface (all opt-in)
-| Var | Meaning | Default |
-|---|---|---|
-| `MO_SANDBOX_BACKEND` | `local` \| `docker` | `local` (host) |
-| `MO_SANDBOX_SCOPE` | `tool` \| `agent` | `tool` |
-| `MO_SANDBOX_IMAGE` | container image | e.g. `mini-ork/agent:latest` |
-| `MO_SANDBOX_CPU` / `_MEMORY` | container limits | unset (no limit) |
-| `MO_SANDBOX_TIMEOUT` | per-exec timeout | inherit node timeout |
-| `MO_SHARED_DRIVE_BACKEND` | `local-bind` (P1a) — drive backing the mount | unset |
-| `MO_SHARED_DRIVE_ROOT` | host dir bind-mounted into every container | run cwd |

-## Files in scope
-- `mini_ork/runtime/backends/__init__.py` (NEW)
-- `mini_ork/runtime/backends/docker.py` (NEW — DockerWorkspace)
-- `tests/unit/test_docker_workspace.py` (NEW — daemon-gated)
-- `mini_ork/agent/minimal.py` (P2 — route tool-exec through Workspace)
-- `mini_ork/cli/execute.py` (P2 — provision drive→workspace, pass mount)
-- `tests/unit/test_sandbox_wiring.py` (NEW — parity + opt-in no-op proofs)
-- this epic file (status updates)
-
-## Risks & mitigations
-- **Dispatch hot-path regression** (Piece 2 touches how every agent runs). →
-  ship Piece 1 (additive, unused) first; Piece 2 behind opt-in env with a
-  parity test proving `local` == today; never default-on.
-- **Container can't reach the LLM gateway** (agent-scope). → start with
-  `tool`-scope only; agent-scope needs egress + keys baked/passed — defer.
-- **Bind-mount perms on colima/macOS** (uid mapping). → test writes both
-  directions in Piece 1 acceptance #2; document the colima mount caveat.
-- **Leaked containers** on crash. → `down()` idempotent `rm -f`; a run-scoped
-  label + a `docker ps -f label=… | rm` sweep in teardown.
-- **Drive is the pet** — never `rm` the mount source in `Workspace.down`; only
-  `SharedDrive.down(ephemeral=True)` may.
-
-## Test / green-gate plan
-- Unit: `test_docker_workspace.py` (skip w/o daemon), `test_sandbox_wiring.py`.
-- Parity: `MINI_ORK_TEST_CMD` scoped to the two new files + existing
-  `test_sandbox_protocol.py` / `test_shared_drive_protocol.py` / `test_run_drive.py`.
-- Full `python3 -m pytest -q` green before each merge.
-- Manual E2E (Piece 2 #3): toy 2-node run writing/reading `/workspace/shared.txt`
-  across two containers.
-
-## Rollout / rollback
-- Worktree-first (`make worktree SLUG=sandbox-p2-docker OWNS="mini_ork/runtime tests"`),
-  merge per phase (Piece 1, then Piece 2). Default path unchanged, so rollback =
-  leave `MO_SANDBOX_BACKEND` unset; no revert needed. Reconcile note: keep local
-  `main` fast-forwarded (see the divergence gotcha from 2026-07-31).
-
----
-
-## Task ledger
-- [x] **P1** DockerWorkspace backend + daemon-gated unit tests — `mini_ork/runtime/backends/docker.py`,
-  `tests/unit/test_docker_workspace.py` (6 tests: registration/error paths + live
-  round-trip w/ bind-mount proof + timeout kill). Commit `3617703d`.
-- [x] **P2a** route agent tool-exec through Workspace (opt-in, `local` parity) —
-  `mini_ork/runtime/agent_workspace.py` (`resolve_agent_workspace`) +
-  `mini_ork/agent/minimal.py` (`MinimalAgent.workspace/exec_cwd`, `run_minimal`
-  lifecycle). Unset backend = byte-for-byte host path; `local` = LocalWorkspace
-  parity; unknown = loud ValueError.
-- [x] **P2b** provision run drive → mount into each container; 2-node E2E —
-  `tests/unit/test_sandbox_wiring.py::test_two_agents_distinct_containers_share_one_drive`
-  (two real containers, node B reads node A's `/workspace/from_a.txt`) +
-  runnable `scripts/demo_docker_shared_drive.py` (verified PASS live 2026-07-31:
-  distinct container ids, drive persists after teardown).
-- [ ] **P2c** provider-transport (agent-scope) routing — behind `MO_SANDBOX_SCOPE=agent`.
-  DEFERRED: needs a purpose-built agent image (coding-agent CLI + keys + egress
-  baked in). `sandbox_scope()` reads the flag today (defaults `tool`); wiring the
-  CLI transport (`dispatch/*`) into a container is the remaining work.
-- [ ] **P3** (separate epic) cloud Volume backends, behavioral-verify cross-link.
-- Merges: P1 `3617703d`; P2 (this batch) logged on merge.
-
-### Verified live (2026-07-31)
-- `scripts/demo_docker_shared_drive.py` → PASS: agent A (container 1) writes
-  `/workspace/shared.txt`, agent B (container 2, distinct id) reads it; drive
-  survives both teardowns (pet vs cattle).
-- colima caveat confirmed + handled: macOS `/var/folders` (TMPDIR) is NOT shared
-  into the VM; tests/demo probe for a bind-visible dir (fall back to `$HOME`).
-- Scope shipped: **tool**-exec routing only (`MO_SANDBOX_SCOPE=tool`, the default).
-  The whole coding-agent CLI in a container (`scope=agent`) is P2c.

+# adaptive_stability.sh — Adaptive Stability Detection for multi-round panel debate.
+#
+# Implements the early-termination signal from:
+#   Hu et al 2025 — "Multi-Agent Debate with Adaptive Stability Detection"
+#   — arxiv:2510.12697
+#
+# Why this exists:
+#   Multi-round panel debate (each round emits a fresh batch of
+#   reviewer_verdict rows in execution_traces) gets diminishing returns
+#   after the panel stabilizes — additional rounds burn compute without
+#   moving the verdict distribution. Static round caps (e.g. "always 3
+#   rounds") either over-spend on already-stable panels or under-spend
+#   on genuinely-contested ones. Adaptive stability detection uses the
+#   round-over-round verdict drift to drive an early-stop signal:
+#   recommend HALT when drift falls below threshold, CONTINUE while
+#   the panel is still moving.
+#
+#   This is the panel-cost dual of the W1-B coalition gate: the latter
+#   refuses to synthesize a coalition; this one refuses to KEEP
+#   DEBATING a stabilized panel.
+#
+# Public API:
+#   mo_check_panel_stability <panel_run_id> <current_round>
+#       → emits structured JSON on stdout:
+#         { "panel_run_id": <str>,
+#           "current_round":   <int>,
+#           "rounds_seen":     <int>,
+#           "score_variance":  <float>,
+#           "verdict_drift":   <float 0..1>,
+#           "stability_threshold": <float>,
+#           "recommendation": "HALT" | "CONTINUE",
+#           "stable": <bool>,
+#           "rationale": "<one sentence>" }
+#       rc=0 always (this is a decision aid, not a gate — the caller
+#         chooses whether to honor the HALT recommendation).
+#
+# Input contract — round numbers must be encoded in trace_id as
+# `tr-<role>-r<N>-<panel_run_id>` so the function can bucket
+# verdicts by round. If round encoding is absent the function returns
+# recommendation=CONTINUE with rationale='round_unencoded_default_continue'
+# (fail-open — never block debate on schema we don't understand).
+#
+# Env knobs:
+#   MO_PANEL_STABILITY_THRESHOLD   verdict_drift below this → HALT.
+#                                  Default 0.10 (10% of voters changed
+#                                  position last round).
+#   MO_PANEL_MIN_ROUNDS            never recommend HALT before this
+#                                  round number. Default 2.
+#   MO_PANEL_MAX_ROUNDS            recommend HALT at this round number
+#                                  unconditionally. Default 5.
+#
+# Requires: bash 4+, python3 + sqlite3, jq.

+# It provides the substrate: load a corpus JSON, validate its
+# shape, and score recipe findings against it for recall.

+# Corpus shape (operator-authored):

+# lib/blame_attributor.sh — delayed side-effect credit assignment (frc-a4).
+#
+# When a later run (bug audit, failing gate, regression test, review finding)
+# localizes a defect to specific file:line ranges, this library attributes the
+# defect back to the prior run/lane(s) that authored those lines, computes a
+# signed penalty in [-1, 0] (via a kimi judge — mockable for tests), and writes
+# rows into the `defect_attributions` table defined by 0045_defect_attributions.sql.
+#
+# Design references: research §6 (Theme D — counterfactual + Shapley split) and
+# research §7 (step #5 — `blame_attributor` lib).
+#
+# Provenance chain:
+#   defect → file:line ranges → `git blame` → commit SHAs
+#                                 → commit trailers (`Mini-ork-run-id:` /
+#                                   `Mini-ork-lane:`) → (run_id, lane)
+#                                 → fallback: commit author-email as lane id
+#
+# Apportionment:
+#   Each line in the blamed range belongs to exactly one commit. We count lines
+#   per (run_id, lane) and apportion the judge-supplied penalty in proportion
+#   to lines-attributed. This is the "cheap Shapley approximation" from
+#   research §6.2: weight by lines-attributed. Sum of apportionments == judge
+#   penalty (signed) by construction.
+#

+#       Reads a defect JSON document, performs attribution, and writes one
+#       defect_attributions row per (found_run_id, blamed_run_id) pair.

+#   blame_attributor_smoke [--tmp DIR]
+#       Self-test that fabricates a mini git repo with two runs' commits,
+#       runs attribution against a synthetic defect, and verifies the rows

+#                            mock so attribution remains testable offline).
+#   MO_BLAME_DRY_RUN         When "1", skips DB writes but still runs the

+# checkpoint.sh — per-node checkpoint primitives for recipe resume.
+#
+# Implements roadmap Phase 3 item 10 (LobeHub deep-review): checkpoint
+# / resume for recipes. The recursive-validate-impl recipe shipped
+# at 2985cae has a recursive loop that, today, replays from node 0
+# on every verifier failure even when nodes 1-3 already passed. That
+# wastes 5-15x the LLM cost it should. This file is the primitive.
+# Wiring into bin/mini-ork-execute (which dispatches each node) is a
+# deliberate follow-up so reviewers can audit this shape first.
+#
+# Public API:
+#   checkpoint_write   <node_id> <status> [<artifact_path>]
+#       Records that node <node_id> finished with <status>
+#       (success | failure | skipped) into $MINI_ORK_RUN_DIR/.checkpoint.json.
+#       Optional artifact path lets the resume runner verify the
+#       produced output still exists before skipping the node.
+#       rc=0 on success.
+#   checkpoint_can_resume <node_id>
+#       Emits "yes" + the artifact_path if the node already finished
+#       with status=success AND any recorded artifact still exists on
+#       disk. Emits "no" otherwise. rc=0 always.
+#   checkpoint_clear   [<node_id>]
+#       Removes a node's checkpoint entry (or the entire file if no
+#       node_id given). Used when the planner mutates the plan and
+#       resume should NOT trust prior nodes.
+#   checkpoint_summary
+#       Emits a human-readable summary table on stdout.
+#
+# State file:
+#   ${MINI_ORK_RUN_DIR}/.checkpoint.json
+#   Shape: { "nodes": { "<node_id>": {"status": "...", "artifact_path": "...",
+#                                     "completed_at": <unix_seconds>} }, ... }
+#
+# Why this exists in honesty terms:
+#   Recursive recipes (recursive-self-improve, recursive-validate-impl)
+#   loop over implement → verify cycles. Each iteration today re-runs
+#   the planner + the lenses from scratch even though their output is
+#   identical to last iteration's. Resume turns this into a pay-once
+#   pattern; the divergence-kill safety net in workflow.yaml keeps
+#   stuck loops from running indefinitely.

+# circuit_breaker.sh — Behavioral liveness gate. Halts a recipe run that is
+# burning cost without producing progress.
+#
+# This is the **behavioral** complement to v0.2 Phase D's cost circuit
+# breaker (MO_DAILY_BUDGET_USD). Cost-CB caps spend; this one catches the
+# failure mode where spend is *under* the cap but the recipe is making
+# zero forward progress — reviewer rejecting the same patch every cycle,
+# implementer writing zero files, artifact_hash frozen, etc.
+#
+# Why this exists:
+#   SAFETY.md forbids "silent self-mutation, hidden rollback, promotion
+#   without measurable utility". A recipe that burns budget on a stuck
+#   loop violates the third clause: it can't be improving anything if
+#   nothing changes. The cost-CB fires only when the daily budget
+#   exhausts, which is the wrong signal — by then the user has already
+#   paid for the no-op cycle. This gate fires on the actual stagnation
+#   signals BEFORE the budget runs out.
+#
+#   Mirrors Wave 1 Phase O ("Panel-failure detection") pattern:
+#   three orthogonal detectors, each fail-open when it can't measure,
+#   joined via a configurable decision policy (majority / OR / AND).
+#   Sister gates: coalition_gate.sh (ρ + family-diversity),
+#                 adaptive_stability.sh (round-over-round verdict drift).
+#   This one: behavioral progress (artifact / verdict / writes).
+#
+#   The three signals are deliberately orthogonal to each other so a
+#   single noisy signal cannot OPEN the breaker on its own under the
+#   default majority policy.

+# citation_verifier_mechanical.sh — recall-floor + wireheading check.
+#
+# Closes two adjacent positioning-doc honest-gaps items:
+#   1. Wave 3 "mechanical citation+coverage verifier" (Sistla 2025
+#      arxiv:2509.26546 + Ficek 2025 / KILT-style citation oracle).
+#   2. "Wireheading check on validators" — verify the validator
+#      actually read the file it cited, instead of confabulating a
+#      file:line anchor for a claim it never grounded.
+#
+# What this does, in concrete terms:
+#   Reads a synthesis-style markdown document and extracts every
+#   citation of the form `path/to/file.ext:LINE` or `path:LINE-LINE`.
+#   For each citation it then:
+#     - resolves the path against $MINI_ORK_ROOT (the repo root),
+#     - verifies the file exists,
+#     - verifies the cited line range is within bounds,
+#     - emits a per-citation pass/fail record.
+#   Finally it computes a coverage ratio (passing citations / total
+#   citations) and a count of unique cited files. If coverage drops
+#   below MO_CITATION_COVERAGE_FLOOR (default 0.8 = 80%), the gate
+#   escalates: the document is not safely grounded.
+#
+# Why this exists, in honesty terms:
+#   Until today the refactor-audit recipe produced findings that
+#   LOOKED rigorous (file:line citations everywhere) but nothing
+#   actually checked the citations resolved. A panel agent that
+#   confabulated a file path was indistinguishable from one that
+#   read the file — the only consequence was a 404 if a human ever
+#   clicked through. This verifier converts citation discipline
+#   from convention into enforcement.
+#
+# Public API:
+#   mo_check_citations <document_path> [<report_dir>]
+#       → JSON on stdout:

+You are the **mini-ork cleaner** — a single-shot agent that fixes a cross-cutting
+blocker on main so paused epics can resume.
+
+## Why you exist
+
+Epic **$EPIC_ID** failed gauntlet with classification **$CLASSIFICATION**.
+Detective rationale: $RATIONALE
+
+You are NOT working on $EPIC_ID's feature. You are unblocking the BASELINE.
+
+## Your brief (verbatim from detective)
+
+$BRIEF
+
+## Live branch-state diff (read FIRST)
+
+You are on branch \`$BRANCH\` (off main). Before doing anything:
+
+\`\`\`
+\$(git log --oneline main..HEAD 2>/dev/null | head -8)
+\`\`\`
+
+Recent fix(baseline) commits ALREADY on main — DO NOT redo these:
+\`\`\`
+\$(git log --since="6 hours ago" --oneline main 2>/dev/null | grep -iE "fix\\(baseline|chore\\(deps|fix\\(types" | head -5)
+\`\`\`
+
+Live type-check error count on MAIN (your canonical target):
+\`\`\`
+main: \$(timeout 30 npm run -s type-check 2>&1 | grep -cE "error TS" 2>/dev/null || echo "?") errors
+\`\`\`
+
+**If main has 0 errors AND your branch's failures are pre-existing on disk only, exit immediately**: write \`${INBOX_DIR}/cleaner-stuck-$TS.md\` saying "main is clean; the worktree just needs a rebase + npm install, not a code fix" and exit. The orchestrator will rebase.
+
+## Mandatory pre-flight (do this BEFORE any edit)
+
+1. \`npm run -s type-check 2>&1 | head -50\` — see the actual errors
+2. \`git diff --name-only HEAD~5..HEAD\` — see what's been recently modified
+3. Confirm: every error you plan to address is in the brief's listed files
+4. **If any error you'd need to fix is in a file NOT mentioned in the brief, STOP.** Write \`${INBOX_DIR}/cleaner-stuck-$TS.md\` and exit. Do NOT extend scope.
+
+## Hard rules — violations = abort + branch discarded
+
+- NO architectural changes. No replacing components with libraries — that's an epic, not a baseline-rot fix.
+- NO refactoring. You read the type error, change the type/import/argument that produces it, run type-check, commit. That's it.
+- NO touching files outside the brief's exact list. If your fix in one file requires touching an unrelated file, write to INBOX and exit.
+- NO commit > 50 lines net change without explicit \`cleaner_brief\` permission. If your fix needs more, you're refactoring not fixing rot.
+- You are on branch \`$BRANCH\` (off main). Stay on this branch.
+- Each commit atomic + conventional (\`fix(baseline): ...\`, \`chore(deps): ...\`).
+- After EACH commit run \`npm run -s type-check 2>&1 | grep -c "error TS"\` and confirm the count went DOWN (never same/up).
+- If you can't complete the brief safely (ambiguity, scope blowup, count won't drop): commit nothing, \`git stash\`, write \`${INBOX_DIR}/cleaner-stuck-$TS.md\` with what's blocking + exact error list, exit.
+
+## Common rot patterns (recognize and apply minimal fix)
+
+- **\`@types/react 18 vs 19 cascade\`** ("Type 'bigint' is not assignable to ReactNode" everywhere) → fix is \`npm update @types/react @types/react-dom --save-dev\` from REPO ROOT, commit \`package-lock.yaml\` only. NOT individual file edits.
+- **Module not found** → the imports likely point at deleted/renamed files. Fix the import path or stub the import. NOT rewriting the module.
+
+## What success looks like
+
+After your commits, the gauntlet that failed for $EPIC_ID should now PASS on main.
+The orchestrator will:
+  1. Verify your work via the gauntlet on this branch.
+  2. Squash-merge your branch to main if gauntlet passes.
+  3. Resume $EPIC_ID against the new clean baseline.
+
+## Output
+
+When done, commit and STOP. The orchestrator picks up the rest.

+#   CN_BASE_URL        Default http://127.0.0.1:28080

+#   MO_DISABLE_CN      If "1" → every read function returns empty {}; hook_post is a no-op.
+#
+# Design rules:
+#   - NEVER block mini-ork on CN being down. Every call has a timeout + fallback to {} or "".
+#   - NEVER write to CN via the tools/store endpoint from mini-ork. Canonical write path
+#     is session ingest only (cc_hooks → WAL → consolidation worker). We push events,
+#     not memories. This keeps CN's substrate pipeline single-entry.
+#   - Cite-tag every atom we surface so the planner prompt can attribute it.

+# coalition_gate.sh — Pre-synthesis family-diversity + ρ hard-block gate.
+#
+# Implements the ρ threshold + family-diversity precondition for any
+# panel-based synthesis path. The gate is designed to fire AFTER the
+# lens nodes have written their execution_traces but BEFORE the
+# synthesizer/publisher consumes them, so the framework refuses to
+# blend a structurally-compromised panel into a "consensus" synthesis.
+#
+# Why this exists:
+#   Bertalanič 2026 ("The Cost of Consensus in Homogeneous Multi-Agent
+#   Debate", arxiv:2605.00914) demonstrates empirically that homogeneous
+#   N-agent debates are WORSE than single-agent self-correction on the
+#   same compute budget — the family-diversity precondition is
+#   load-bearing for the multi-agent claim, not decorative. Rajan 2025
+#   ("CodeX-Verify", arxiv:2511.16708) proves a multi-agent submodular
+#   gain holds IFF pairwise output correlation ρ stays below ~0.25.
+#   Until today the framework MEASURED ρ post-cycle for telemetry only.
+#   This gate converts measurement into enforcement.
+#
+# Public API:
+#   mo_check_panel_coalition <panel_run_id> <recipe>
+#       → emits structured JSON on stdout:
+#         { "verdict": "panel_diverse" | "COALITION_ABORT",
+#           "reason":  "ok" | "high_rho" | "family_collision" | "both",

+#           "family_count": <int>,
+#           "rationale":    "<one sentence>" }
+#       rc=0 when both checks pass (or topology library unavailable —
+#         fail-open by design; the gate cannot block when it cannot
+#         measure, but emits verdict=indeterminate so callers can log).

+# Problem: concurrent mini-ork runs cannot run safely because the lane policy
+# (config/agents.yaml) is read LIVE, per-dispatch, by the dispatch resolvers
+# (lib/decision_service.sh, lib/lane-helpers.sh). Editing the global
+# agents.yaml while a run is in flight mutates that run's routing on its next
+# node — so two parallel runs (or one run + an operator editing lanes) collide.

+# Fix: a run FREEZES its effective lane policy into its run-dir at launch
+# (mo_snapshot_run_config), and every dispatch-time resolver reads run-dir-FIRST
+# (mo_resolve_agents_yaml). Consequences:
+#   - editing the global agents.yaml never perturbs an in-flight run;
+#   - concurrent runs hold independent frozen policies;
+#   - a run is reproducible — its lane policy travels with its run-dir.
+#
+# This is the first concrete slice of the actor-per-run isolation epic and is a
+# design pattern (not a band-aid): it survives the Bash→Python migration.

+#       Why retrieve fallback: capsule depends on atoms having `kind`

+#       under-populated substrate the capsule may return nothing where
+#       retrieve still finds nearest-neighbour hits.
+#
+#       Why exists at all: mini-ork's planner has only ever seen local

+# PR-3 of the agent-context-pack epic. Maps mini-ork's 8 workflow node
+# types to specific CN endpoint combinations so each role gets the
+# slice of substrate it actually needs:
+#
+#   planner            → strategic (risks + decisions + topics + blockers)
+#   researcher         → wide recall (semantic + feature history)
+#   implementer/worker → tactical (recent editors, adjacent deliveries, graph neighbours)
+#   reviewer/verifier  → failure-shaped (capsule filtered to failures + verifications)
+#   reflector          → narrative (prior-run trajectories + same-intent runs)
+#   publisher/rollback → shipment + blocker awareness
+#
+# Pre-PR-3 every role got the same flat retrieve query. The result was
+# universally mediocre — planner missed risk_flags, implementer missed
+# adjacent feature deliveries, verifier missed prior failures. The
+# role-pack split lets each role consume the substrate at the right
+# angle without changing the substrate itself.
+#
+# Public API:
+#   context_role_pack_md <role> <task_brief_path> [files_csv]
+#       → emits a multi-section markdown block on stdout
+#       → empty when CN unreachable or MO_DISABLE_CN=1 (silent)
+#
+# Each role's pack composes 2-4 CN calls. Calls run sequentially (not

+# under planner LLM wall-clock).

+# coord_gate.sh — PreToolUse-style coordination gate for Track B6.
+#
+# Sits in front of any tool/file-edit dispatch and consults the lease registry
+# (lib/coord_registry.sh) before the edit lands. Two modes:
+#
+#   advisory  — emit a visible "WAIT before editing <path>" nudge to stderr
+#               and return 0 so the operation is NOT blocked. Designed for
+#               noisy feedback without breaking pipelines.
+#   strict    — return non-zero (rc=11) when the requested op would conflict
+#               with an active coordination lease. Opt-in per scope: the
+#               caller must export COORD_GATE_SCOPE=<path-prefix> AND set
+#               COORD_GATE_MODE=strict to enable the deny path.
+#
+# Counters (incremented in-place under ${COORD_GATE_METRICS_FILE}):
+#   coord_leases_held       — non-zero whenever an active lease covers the path
+#   coord_queue_depth       — number of waiters currently in the registry
+#   coord_deadlocks_broken  — bumped when a deadlock cycle aborts an acquire
+#   coord_ttl_expirations   — bumped on each access that prunes >=1 expired lease
+#
+# Contention audit (bounded ring buffer under ${COORD_GATE_AUDIT_FILE}):
+#   - Appends a record on every conflict / denied / deadlock event.
+#   - Capped at COORD_GATE_AUDIT_MAX (default 64). When full, oldest record
+#     is dropped so the file stays bounded regardless of contention volume.
+#   - coord_gate_audit [N] returns the most recent N records (default all).
+#
+# Public API:
+#   coord_gate_check <agent> <path> <mode>          → rc=0 advisory, rc=11 strict-deny
+#   coord_gate_metrics                              → prints counter JSON to stdout
+#   coord_gate_metrics_field <name> [default]       → prints integer value
+#   coord_gate_audit [N]                            → prints JSON (most-recent first)
+#   coord_gate_record_deadlock                      → bumps coord_deadlocks_broken
+#   coord_gate_record_ttl_expiration [delta]        → bumps coord_ttl_expirations
+#
+# Environment knobs (all optional):
+#   COORD_GATE_MODE=advisory|strict                 (default advisory)
+#   COORD_GATE_SCOPE=<path-prefix>                  (strict mode only; default /)

+# coord_registry.sh — Single-host lease registry for scoped path-prefix claims.
+#
+# Public API:
+#   coord_acquire <agent> <path> <mode> [ttl_seconds]  → lease_id on stdout
+#   coord_release <lease_id>                            → exit 0 on success
+#   coord_renew   <agent> <lease_id> [ttl_seconds]     → exit 0 on success
+#
+# Defaults and limits (exportable so callers can introspect):
+#   COORD_REGISTRY_DEFAULT_TTL  = 120   seconds (used when ttl is omitted)
+#   COORD_REGISTRY_MAX_TTL      = 3600  seconds (1 hour; requested ttls cap here)
+#
+# Conflict semantics (many-readers-or-one-writer on path-prefix overlap):
+#   - "read"  + "read"   on overlapping prefixes       → ALLOW (concurrent reads)
+#   - "read"  + "write"  on overlapping prefixes       → BLOCK
+#   - "write" + "write"  on overlapping prefixes       → BLOCK
+#   - any mode on non-overlapping prefixes             → ALLOW
+#   - A blocked acquisition records waiter -> holder edges. If adding those
+#     edges creates a wait-for cycle and the requester is the cycle's lowest
+#     priority participant, the requester is aborted with
+#     {"status":"abort","reason":"deadlock"} instead of preempting a holder.
+#
+# Prefix overlap definition (component-aligned):
+#   - Two paths overlap iff either is a component-aligned prefix of the
+#     other. "src/api" overlaps "src/api/x.rs" (the former is a prefix of
+#     the latter). "src/api" does NOT overlap "src/ap" (appending "/" forces
+#     strict component alignment so "src/ap/" is not a prefix of "src/api/").
+#   - Mode must be exactly "read" or "write"; anything else is rejected
+#     so unknown modes cannot silently bypass conflicts.
+#
+# Time-bounded leases (TTL self-healing):
+#   - Every coord_acquire / coord_release / coord_renew loads state and
+#     prunes entries whose expires_at <= now BEFORE deciding what to do.
+#     A crashed holder's claim heals automatically on the next read because
+#     the expired lease is treated as free — no sweeper needed.
+#   - coord_renew is permitted only for the current holder. If the supplied
+#     agent does not match the stored agent, renew is rejected (rc=3) so a
+#     leaked lease_id cannot indefinitely extend someone else's claim.
+#   - Requested ttl values are silently capped at COORD_REGISTRY_MAX_TTL
+#     so a misconfigured caller cannot pin the registry forever.
+#
+# Other invariants:
+#   - Leases are time-bounded by absolute epoch (seconds).
+#   - State lives at ${COORD_REGISTRY_STATE_FILE} if set, otherwise
+#     ${MINI_ORK_RUN_DIR}/state/coord-registry/leases.json, otherwise
+#     ${MINI_ORK_HOME}/state/coord-registry/leases.json, otherwise
+#     ${HOME}/.mini-ork/state/coord-registry/leases.json.
+#   - Cross-process safety on a single host uses flock on a sibling lockfile.
+#   - Lease ids are opaque, non-empty, randomly generated. coord_release on
+#     an unknown id returns non-zero (use this for cleanup paths).
+#   - Agent priority is optional and only used for deadlock-cycle requester
+#     abort decisions. Higher numbers are higher priority. Set
+#     COORD_REGISTRY_AGENT_PRIORITIES to "agent-a=10,agent-b=20" or
+#     COORD_REGISTRY_AGENT_PRIORITY_<sanitized agent> for focused tests.

+#   Krippendorff α (Nasser 2026 arxiv:2601.05114) measures *agreement
+#   reliability* — a low α reveals noisy / random panels. But α is BLIND
+#   to authority-capture, the failure mode where one confidently-stated
+#   voice drags the others toward the wrong answer. Such a panel scores
+#   HIGH α (because everyone converges) while being structurally
+#   compromised. CW-POR is the orthogonal axis: the rate at which the
+#   panel adopts a high-confidence wrong answer over a low-confidence
+#   correct one, weighted by the confidence delta between them. A
+#   healthy panel can co-exist high α + low CW-POR; a captured panel

+#   mo_deadline_check <run_id>
+#       Returns 0 while budget remains, rc=2 once exhausted. The FIRST
+#       rc=2 also writes ${run_dir}/.deadline-hit sentinel JSON and emits
+#       a `deadline_hit` JSON log line on stderr. Subsequent calls keep

+#       Returns rc=0 on start OR rc=0 on no-op fallback when
+#       Omnigent is absent (operator-visible warning is logged).
+#       Returns rc=2 on a genuine start failure.
+#   mo_egress_proxy_stop <run_dir>
+#       Clean shutdown. Removes the proxy-addr file.
+#   mo_egress_inject_secret <run_dir> <secret_name> <target_host>
+#       Records a secret-injection RULE for the proxy. Does NOT

+# all oracle gates once-per-cycle at a single chokepoint inside
+# bin/mini-ork-execute (modeled on the measure_topology call site).
+# That chokepoint requires the gates to be REGISTERED in the gate_registry
+# table before gate_run_all can dispatch them. This bootstrap runs at the
+# top of the publisher case-branch and idempotently inserts the gate
+# records.

+# Reframed to ask "what about THIS RECIPE'S design would have made the

+_GRADIENT_EXTRACTOR_PROMPT_TEMPLATE='You are a recipe-design improvement analyst.
+
+Given the execution trace below, extract 0 to 5 textual gradients — specific,
+actionable improvement signals. The trace may describe an algorithmic
+workflow (planner → implementer → verifier) OR a coordination workflow
+(4 lenses → synthesizer → publisher). Find what about THIS RECIPE design
+would have made the outcome better.
+
+Five target families (pick the most specific that fits each gradient):
+
+  1. "workflow.node.<name>"           — algorithmic improvement to one node
+                                        (e.g. planner missed a step, verifier
+                                        accepted a bad artifact)
+  2. "agent.<role>.prompt"            — prompt-level improvement (e.g. the
+                                        lens prompt produced shallow output;
+                                        the synthesizer prompt missed an axis)
+  3. "workflow.edge.<name>"           — dependency / sequencing refinement
+                                        (e.g. depends_on should be
+                                        supplies_context_to; this edge needs
+                                        a retries policy)
+  4. "verifier.<name>"                — verifier-script logic gap
+                                        (e.g. the grep-assert missed a
+                                        boundary condition)
+  5. "workflow.recipe.<recipe_name>"  — RECIPE-LEVEL shape suggestion when
+                                        the issue is the dispatch topology

+Important: if the trace is from a coordination-shaped recipe (audit,
+synthesis, multi-lens debate), prefer "workflow.recipe.<name>" or
+"agent.<role>.prompt" gradients — those are where the leverage actually
+lives. Do NOT respond with [] just because no algorithmic bug stands out;
+coordination shapes ALWAYS have a recipe-design improvement to surface
+(family-diversity, verifier contract, synthesis aggregation, etc).
+
+Respond ONLY with a JSON array of gradient objects. Each object must have:
+  "target"          : string — one of the 5 target families above
+  "signal"          : string — what was observed (1-2 sentences)
+  "suggested_change": string — concrete recommendation (1-2 sentences)
+  "confidence"      : number — 0.0 to 1.0
+
+If after honest analysis you genuinely find nothing to improve (rare —
+audit yourself before defaulting), respond with []. No prose, no markdown
+fences, only the JSON array.'

+#!/usr/bin/env bash
+# harness_wrapper.sh — wrap a full coding-agent harness as a workflow node.
+#
+# Implements the harness-wrapper half of Epic E6 of the Omnigent-
+# improvement plan. The Harvey pattern Databricks describes — open
+# worker model + frontier advisor caller — assumes the worker is a
+# full harness with tools and a workspace, not just a single LLM
+# call. Mini-ork's lane providers (lib/providers/cl_*.sh) wrap
+# clients, not harnesses. This file closes that gap.
+#
+# Supported harnesses: claude-code, codex-cli, gemini-cli.
+#
+# Dispatch contract (uniform across all three CLIs):
+#   1. The workspace is initialized as a git repo (if not already).
+#   2. The kickoff body is read + concatenated into the harness prompt.
+#   3. The CLI is invoked with cwd=workspace + the prompt on stdin
+#      OR via the CLI's argv-prompt flag, whichever shape the CLI
+#      actually supports.
+#   4. After the CLI exits, git diff captures every change as the
+#      unified diff. The harness writes harness-verdict.json with
+#      diff_lines + exit_code + harness identity.
+#
+# Why git-diff capture beats stdout parsing:
+#   The original stub heuristic scanned stdout for "^diff --git"
+#   anchors. Real coding agents typically write changes through tool
+#   calls (Write/Edit/Bash patch) — the assistant transcript that
+#   reaches stdout describes the work but does not include a
+#   unified-diff dump. git-diff against the workspace's HEAD captures
+#   exactly what changed regardless of how the CLI emitted it.
+#
+# Public API:
+#   mo_harness_wrap <harness_name> <kickoff_path>
+#       Writes the unified diff + verdict to MINI_ORK_RUN_DIR.
+#       Returns 0 when the verdict file is written (even when the
+#       CLI exited non-zero or was absent); returns 2 only when
+#       arguments are malformed.
+#
+# Env knobs:
+#   MO_HARNESS_TIMEOUT_S    Per-CLI wall-clock timeout. Default 900.
+#   MO_HARNESS_DRY_RUN      Set to 1 to skip the actual CLI dispatch
+#                            and emit a synthetic "dry_run" verdict.
+#                            Used by the self-test to avoid burning
+#                            tokens on a real harness call.
+#   MO_HARNESS_PROMPT_FILE  Override the kickoff path with a
+#                            preprocessed prompt file (for callers
+#                            that want to layer system instructions).

+Classify this mini-ork worker failure. Be specific in error_pattern —
+it must be a regex that captures THIS class of failure without matching
+unrelated errors (no bare "error" or "fail"; include distinguishing

+rebase-and-retry for code-state issues, escalate-human only when truly
+no automated recovery makes sense.
+
+Few-shot examples:
+  - TS2307 'Cannot find module' → failure_class=baseline_rot,
+    error_pattern="TS2307|Cannot find module",
+    recovery_action=cleaner-on-main
+  - 429 'rate_limit' → failure_class=rate_limit,
+    error_pattern="429|rate.*limit",
+    recovery_action=wait-and-retry,
+    recovery_args={"wait_s":30}
+  - 'Cannot find tool Task' (GLM lacks subagents) → failure_class=subagent_unsupported,

+# honest_ci_gate.sh — per-finding confidence intervals from lens votes.
+#
+# Closes the positioning-doc calibration-list item "Honest confidence
+# intervals on every claim" (Dai 2025 *Semantic Triangulation*,
+# arxiv:2511.12288). The shipped framework already measures
+# panel-level agreement via Krippendorff α (3d1e815) and citation
+# grounding via mechanical citation coverage (31f7808), but every
+# individual finding still emits as a bare integer severity ("P1")
+# without an uncertainty band. Dai 2025's recommendation is to
+# attach a CI per claim so downstream consumers can prefer
+# narrow-CI findings over wide-CI ones.
+#
+# What this does, in concrete terms:
+#   Reads a JSON file shaped:
+#     { "findings": [
+#         { "id": "F-001",
+#           "title": "...",
+#           "lens_votes": {"glm": 2, "kimi": 3, "codex": 2, "minimax": 3}
+#         }, ... ] }
+#   For each finding it computes:
+#     - n          : the number of lens votes
+#     - mean       : arithmetic mean of the integer/float severity votes
+#     - sd         : sample standard deviation (n-1 divisor)
+#     - sem        : standard error of the mean (sd / sqrt(n))
+#     - ci_low/high: 95% CI = mean ± t_{0.975, n-1} * sem (interval scale)
+#     - ci_width   : ci_high - ci_low (the "honesty band")
+#
+# It then writes an augmented JSON with `confidence_interval` on every
+# finding, plus a summary line: how many findings have wide CIs
+# (ci_width >= MO_CI_WIDTH_CEILING). Wide-CI findings are operator-
+# escalable: the panel did not converge enough to defend them.
+#
+# Public API:
+#   mo_compute_finding_cis <findings_json> <out_path>
+#       rc=0 always (gate is informative, not blocking by default —
+#       callers compose it with promotion_gate.sh if they want hard-
+#       block semantics).
+#   mo_check_ci_widths <findings_json> [<report_dir>]
+#       Like above but also emits structured JSON verdict for the
+#       gate-runner integration:
+#         { "verdict":     "ci_within_band" | "CI_TOO_WIDE" | "indeterminate",
+#           "reason":      "ok" | "wide_cis" | "no_findings" | "missing_input",
+#           "wide_count":  <int>,

+#           "augmented_path":     "<report_dir>/findings-with-cis.json",
+#           "rationale":   "<one sentence>" }
+#       rc=0 on ci_within_band or indeterminate; rc=1 on CI_TOO_WIDE.
+#
+# Env knobs:
+#   MO_CI_CONFIDENCE         Confidence level. Default 0.95.
+#   MO_CI_WIDTH_CEILING      A finding is "wide" when ci_width >=
+#                             this. Default 2.0 (units of the underlying
+#                             severity scale; e.g. on a P0..P3 scale a
+#                             2-point band means the panel can't even
+#                             agree on the priority class).
+#   MO_CI_WIDE_RATIO_CEILING Maximum acceptable wide-ratio.
+#                             Default 0.3 (30% — Dai 2025 recommended
+#                             cut for high-stakes audits).

+# ("Evaluative Fingerprints in Multi-Agent LLM Review", arxiv:2601.05114)
+# reports α=0.042 cross-family vs much higher same-family on identical
+# tasks — i.e., the multi-agent claim is structurally honest only when
+# the panel disagrees enough to be doing independent work. The dual-edge
+# observation is that when α is ALSO very low (< ~0.4), the panel is
+# noise rather than signal and a single point-verdict cannot be defended.
+#
+# This gate implements the operator-facing form: compute α across the
+# panel's first-round per-item judgments; if α < MO_ALPHA_THRESHOLD,
+# emit ALPHA_ESCALATE and refuse to publish until a human resolves.
+#
+# Public API:
+#   mo_check_panel_alpha <run_dir>
+#       → JSON on stdout:
+#         { "verdict":  "panel_calibrated" | "ALPHA_ESCALATE" | "indeterminate",
+#           "reason":   "ok" | "low_alpha" | "insufficient_panel" |

+#           "score_matrix_path": "<run_dir>/panel-alpha-scores.tsv",
+#           "rationale":   "<one sentence>" }
+#       rc=0 when α ≥ threshold (panel calibrated), OR when the gate
+#         cannot measure (insufficient panel, no scores, python missing)
+#         — fail-open by design, with verdict=indeterminate. The
+#         framework's safety property holds because callers always
+#         render the verdict text, not just the exit code.
+#       rc=1 when ALPHA_ESCALATE triggers (low_alpha).
+#
+# Env knobs:
+#   MO_ALPHA_THRESHOLD    α floor below which the gate escalates.
+#                         Default 0.4 (Nasser 2026's recommended cut).
+#   MO_ALPHA_MIN_LENSES   Minimum panel size for the gate to engage.
+#                         Default 2; below this, verdict=indeterminate.
+#   MO_ALPHA_INPUT_PATH   Override the score-source path. Default:
+#                         <run_dir>/panel-verdict.json with shape
+#                         { lens_scores: { <lens>: [<score1>, <score2>, ...] } }.
+#                         Each lens's array must have identical length =
+#                         number of scored items (DoD probes, rubric
+#                         dimensions, etc.).
+#
+# Why fail-open on indeterminate:
+#   A gate that cannot measure should not silently block. The verdict
+#   text makes the operator's audit honest ("we couldn't tell"), the
+#   exit code keeps the dispatch loop forward-moving. Same shape as

+# lane_router.sh — GRPO-style relative-advantage lane routing.
+#
+# Track B item 4 (arXiv:2601.22607 verifiable-reward GRPO + 2603.02701
+# Graph-GRPO for multi-agent topologies). When a recipe dispatches a
+# lens panel (codex + kimi + glm + minimax in parallel), each lens
+# produces a comparable trajectory. We score each by the normalized
+# cross-objective reward_g (set by trace_store.sh from
+# reward_value/anchor/direction) and compute:
+#
+#   relative_advantage[i] = score[i] - mean(scores in group)
+#
+# The group key is (objective_domain, task_class, node_type, code_region) when
+# code_region is present, and the legacy (objective_domain, task_class,
+# node_type) key when code_region is NULL/absent. score is sourced only from
+# reward_g; rows with reward_g IS NULL are skipped — falling back to
+# process_reward or status would reintroduce raw cross-objective reward
+# contamination the normalized reward_g column exists to remove.
+#
+# Positive advantage = "this lens outperformed peers on this
+# objective_domain + task_class + node_type". Negative = "this lens
+# underperformed". Aggregated into agent_performance_memory.
+# relative_advantage and used by the lane router to bias future picks
+# toward consistently-winning lanes.
+#
+# Public API:
+#   lane_router_recompute_advantages [--since EPOCH]
+#       Walk recent execution_traces grouped by (objective_domain,
+#       task_class, node_type). For each group, compute per-lane scores
+#       from normalized reward_g plus the group mean, then UPSERT
+#       agent_performance_memory rows with relative_advantage. Rows
+#       with reward_g IS NULL are skipped.
+#
+#       frc-a5: when migration-0045's `defect_attributions` table is
+#       present, the per-region (acc_region) slice also folds each
+#       row's exponentially decayed `penalty` into the blamed lane's
+#       `lane_region_advantage.relative_advantage`. The decay formula is
+#       `decay = 0.5 ** (age_days / decay_halflife_days)` and `penalty`
+#       is signed negative (range [-1, 0]), so blamed lanes drop and
+#       unblamed lanes (no matching attribution) are unchanged. Global
+#       (agent_performance_memory) and per-domain (lane_domain_advantage)
+#       slices are intentionally untouched — penalties are region-scoped
+#       by design.

+# langfuse_score_mapper.sh — verdict/rollback/promotion → trace score.
+#
+# Implements roadmap Phase 3 item 8: Langfuse score mapping. The
+# planned OTel-Langfuse exporter (docs/architecture/otel-langfuse.md)
+# emits one trace per run. This file converts mini-ork's structured
+# verdicts, rollback events, and promotion decisions into numeric
+# Langfuse trace scores so traces self-rank by quality without
+# operator effort.
+#
+# Score conventions (Langfuse "numeric" scores, -1.0 ..= +1.0):
+#   reviewer APPROVE                        →  +1.0
+#   reviewer REQUEST_CHANGES                →  -0.5
+#   reviewer ESCALATE                       →   0.0  (operator decides)
+#   verifier pass                           →  +0.5
+#   verifier fail                           →  -0.5
+#   verifier vacuous                        →  -0.25 (nothing checked is not pass)
+#   panel COALITION_ABORT (lib/coalition_gate)   → -0.75
+#   panel ALPHA_ESCALATE  (lib/krippendorff)     → -0.5
+#   panel CITATION_UNDERCOVERED                  → -0.5
+#   panel REFUTE_FAILED  (lib/refute_or_promote) → -0.75
+#   panel CI_TOO_WIDE    (lib/honest_ci)         → -0.25
+#   rollback fired                          →  -1.0
+#   promoted (promotion_records.decision=promoted)         → +1.0
+#   quarantined                                            → -1.0
+#   pending_human_approval                                 →  0.0

+# Public API:
+#   langfuse_score_for_verdict <verdict_json>
+#       Reads a verdict-shaped JSON object from stdin OR from the
+#       arg path. Emits one JSON line per scoreable event:
+#         {"name": "<event_name>",
+#          "value": <numeric_score>,
+#          "data_type": "NUMERIC",
+#          "comment": "<one-line rationale>"}
+#       Multiple events in one input emit multiple lines.
+#       rc=0 always.
+#   langfuse_score_table
+#       Prints the score table for operator review (no input).
+#
+# Why this exists in honesty terms:
+#   The framework already records verdicts and rollback events in
+#   structured form. Without the mapping, every team writes its
+#   own verdict→score conversion when wiring to a trace platform —
+#   that produces inconsistent benchmarks across organizations
+#   running the same recipe. Standardizing the mapping makes the
+#   numbers comparable.

+# llm-dispatch.sh — uniform LLM dispatcher for all v2/v3 stages + layers.
+#
+# Handles the two cl_*.sh shapes:
+#   - cl_codex.sh / cl_gemini.sh — proper executables (have shebang, call
+#     their respective CLI directly). Invoke directly with flags.
+#   - cl_sonnet.sh / cl_kimi.sh / cl_glm.sh / cl_minimax.sh / cl_opus.sh —
+#     sourceable env-export scripts that pin ANTHROPIC_* env vars. Must be
+#     SOURCED in a subshell then `claude` invoked separately.
+#
+# Public API:
+#   mo_llm_dispatch <model> <prompt-text> <output-file> [timeout_s] [max_turns]
+#
+# Returns: 0 on success (output captured in output-file), non-zero on failure.
+# Stderr captured to <output-file>.err.log.
+#
+# Examples:
+#   mo_llm_dispatch sonnet "$(cat prompt.md)" out.txt 1500 60
+#   mo_llm_dispatch codex  "$(cat prompt.md)" out.txt 1500

+# Wraps state.db reads/writes for the 14 memory tables added in
+# migration 20260528-mini-orch-v2v3-shared-memory.sql.
+#
+# Design rules:
+#   1. EVERY memory write captures a reflection (git SHA + timestamp +
+#      reflected_substrate JSON). Read-side staleness detection is in
+#      lib/reflect.sh (Phase 5.5).
+#   2. JSON columns are passed/returned as raw JSON strings. Caller
+#      handles JSON parsing.
+#   3. cycle_id is a required input to most writes — passed by the
+#      dispatcher. Default = "cycle-$(date +%Y%m%d-%H%M%S)".
+#   4. via_gate defaults are baked into the table schema; callers can
+#      override.
+#   5. Parameter binding via python3 sqlite3 argv — no heredoc
+#      interpolation (which collides with bash $$ PID expansion).

+#   2. Auto-apply LOW-RISK recoveries:
+#        - cleaner-on-main: dispatch cleaner.sh against main worktree
+#        - rebase-and-retry: git -C <worktree> rebase main; flip epic

+#        - wait-and-retry: sleep + flip to PENDING (rate-limit recovery)
+#   3. Higher-risk recoveries (switch-agent / shrink-scope) emit a
+#      brain hint via mo_event but leave epic at ESCALATE for the user.
+#   4. Terminal recoveries (escalate-human / mark-wontfix / no-op)
+#      keep epic at ESCALATE — same as before this bridge existed.
+#
+# Side effects:

+# anything that wants to react in real-time instead of polling
+# run_events / mo_events).
+#
+# The hook is a single shell command supplied via the MINI_ORK_ON_EVENT

+#
+#   $1  event_type   e.g. "node_start" | "node_end" | "child.completed"
+#   $2  run_id       e.g. "run-1781509524-39638"
+#   $3  payload_json e.g. {"node_id":"planner","node_type":"planner"}
+#
+# Failure mode: any non-zero exit, timeout, or missing command is logged
+# to stderr and SWALLOWED. Observability must never break dispatch.
+#
+# Example use:
+#   export MINI_ORK_ON_EVENT="$HOME/.config/mini-ork/event-hook.sh"

+#
+# Reference handlers live under examples/event-hooks/:

+#   - webhook.sh — POST JSON to a URL; great for chat / dashboards

+#
+# See docs/EVENT-HOOKS.md for the full contract.

+# Why this exists:
+#   Adversarial panel review (panel-A) needs three independent controls
+#   to keep lens-identity from leaking into the verdict:
+#     (a) anonymize  → opaque response labels A/B/C/... so reviewers
+#                     can't privilege a family by name (label bias).
+#     (b) aggregate  → Borda sum + mean-rank to surface consensus
+#                     winner from the now-anonymous rankings.
+#     (c) permute    → randomized review order so position-of-
+#                     presentation doesn't bias per-item scores.
+#   These are STANDALONE mechanics — they take a directory in and emit
+#   a directory + JSON file out, with no knowledge of mini-ork
+#   recipes, gate libraries, or LLM dispatch. PANEL-b (out of scope
+#   here) wires them into the panel-runner.
+#
+# Public API:

+#   - Input errors emit a message on stderr and return rc!=0.
+#     No silent fallbacks: if the path is missing, fail loudly.
+#   - label_map.json path is ${out_dir}.label_map.json (sibling).

+#!/usr/bin/env bash
+# lib/policy_store.sh — store-port seam over lib/db_open.sh (v0.2-pt36 RLM-3).
+#
+# Central backend selector for the brain libraries (lane_router,
+# process_reward, gradient_extractor). The SAME learning-loop implementation
+# targets SQLite (dev / eng-team, default) AND Postgres (serving /
+# book-gen, per-tenant) by sourcing this lib and going through
+# mo_store_assert_sqlite / mo_store_db_path / mo_store_py_connect_snippet
+# / mo_store_py_pragmas_snippet.
+#
+# Backend selection:
+#   MO_STORE_BACKEND=sqlite    (default; preserves eng-team behavior)
+#   MO_STORE_BACKEND=postgres  (stub; fails predictably until the real
+#                              researcher-side PG impl lands)
+#
+# v0.2-pt36 deliberately stops short of a real PG implementation. The
+# Postgres backend is wired ONLY enough to abort before any sqlite3 call,
+# so a researcher landing the real PG writer can swap the stub without
+# re-architecting callers. Eng-team SQLite behavior is unchanged.
+#
+# Public API:
+#   mo_store_backend                 — print "sqlite" or "postgres"
+#   mo_store_assert_sqlite           — die 78 (EX_CONFIG) if backend != sqlite
+#   mo_store_db_path                 — print resolved DB path
+#                                       (MO_STORE_DB → MINI_ORK_DB → default)
+#   mo_store_py_connect_snippet      — emit backend-aware Python connect code
+#                                       for use inside `python3 - <<PY` heredocs
+#                                       (substituted via $(mo_store_py_connect_snippet))
+#   mo_store_py_pragmas_snippet      — emit backend-aware Python pragma code
+#                                       (same substitution shape)
+#
+# Conventions:
+#   - DB path resolution is centralized here. lib/lane_router.sh and
+#     lib/process_reward.sh use $(mo_store_db_path) instead of re-deriving
+#     STATE_DB from MINI_ORK_DB / MINI_ORK_HOME / pwd.
+#   - SQLite-direct callers (lane_router, process_reward today) call
+#     mo_store_assert_sqlite at function entry. Postgres callers MUST
+#     route through the Python snippets above; calling sqlite3 CLI or
+#     sqlite3.connect directly while MO_STORE_BACKEND=postgres will hit
+#     the assert and exit 78 before any DB call.
+#   - lib/db_open.sh remains the low-level connection primitive
+#     (mo_sqlite, mo_sqlite_py_pragmas). This seam adds policy, not
+#     mechanics, on top.
+
+# Strict mode only when executed directly — never leak set -u/pipefail onto a
+# parent that sources this lib (matches lib/lane_router.sh / lib/process_reward.sh).

+# pricing_strategy.sh — config-driven (provider, model) → rate lookup.
+#
+# Closes the roadmap's Agent-ops hardening Phase 2 item 6: pricing
+# strategy table. Replaces the inline cost math in lib/llm-dispatch.sh
+# (and downstream consumers) with a config-driven lookup so:
+#   - Rates are version-controlled YAML, not buried in shell.
+#   - Same lookup serves input / output / cache_read / cache_write.
+#   - Pricing updates are config edits, not code edits.
+#   - The framework never calls home; operators tune the YAML to
+#     whatever rates the actual contract specifies.
+#
+# Public API:
+#   pricing_lookup <provider> <model> <token_kind>
+#       → emits the matching rate (USD per million tokens) on stdout.
+#       Returns "0" + warns on stderr when:
+#         - the (provider, model, token_kind) triplet is missing,
+#         - the YAML cannot be parsed,
+#         - python3 is unavailable.
+#       Token kinds: input | output | cache_read | cache_write.
+#
+# Source of truth:
+#   ${MINI_ORK_HOME:-.mini-ork}/config/pricing.yaml (override via
+#   MO_PRICING_YAML). See that file for shape + commented rationale.
+#
+# Wiring into lib/llm-dispatch.sh and the downstream cache-aware
+# cost accounting (P2.5) is a deliberate follow-up — this commit
+# only adds the lookup primitive + the YAML so the substrate exists
+# before the call sites change.

+#   + 0.20  tool_calls non-empty (agent actually did work)        [capped, see below]
+#   + 0.10  files_written or files_read non-empty (artifacts)      [capped, see below]
+#   + 0.15  reviewer_verdict in {APPROVE, pass, success, ok}, gated on
+#           status == success AND not same-family (see verifiable-first note)
+#   + 0.10  duration_ms in [1000, 600000] (not too fast, not too slow)
+#   + 0.05  cost_usd > 0 (real LLM invocation, not a stub)
+# Total maxes at 1.0, floors at 0.0; partial credit is the point.
+#
+# Activity cap (Goodhart guard): by default the combined contribution of
+# tool_calls + files_read/written is clamped at ACTIVITY_CAP=0.15 so that a
+# noisy failed trace with high activity cannot outscore a clean bare-success
+# trace. Without this clamp, status=failed + tool_calls=5 + files=2 + cost>0
+# lands at 0.45 while status=success with no work lands at 0.40 — i.e. the
+# "do more bad work" path wins. Set MO_PRM_ACTIVITY_CAP=0 to reproduce the
+# legacy uncapped weighting for A/B comparison.
+#
+# Verifiable-first (FE): the +0.15 reviewer_verdict term is gated behind
+# status == success so an adversarial / noisy LLM judge cannot lift a
+# failed trace above 0.5. Same-family decontamination (zeroing the verdict
+# term when agent_version_id contains opus/minimax/glm/kimi) has been
+# REMOVED: the doer's lane is not a valid proxy for the reviewer's lane
+# without a real reviewer_model column in execution_traces, and the
+# asymmetric stripping of +0.15 from opus/minimax/glm/kimi runs biased
+# GRPO group ranking. Same-family neutralization awaits a schema change.
+# PRM copies in prm_score_trace and prm_backfill MUST stay behaviorally
+# identical: the weight table below is mirrored verbatim in prm_backfill.
+# Drift between the two causes process_reward to diverge between
+# single-trace writes and bulk backfills, silently breaking the router.
+#

+#   prm_score_trace   <trace_id>        compute + UPDATE process_reward
+#   prm_backfill      [--since EPOCH]   bulk-score every recent trace
+#   prm_low_scoring   <task_class> N    print N traces with reward < 0.5
+#

+# Bug it fixes: the planner can emit profile_status=needs_answers while asking
+# ZERO human_questions — i.e. it read the kickoff, decided it had everything,
+# and asked nothing. The downstream gate (bin/mini-ork-plan) then runs the
+# interactive / auto-answer branches, which have nothing to ask, fall through to
+# "[skip] no answers provided", and BLOCK dispatch — even though the LLM
+# reasoning succeeded. A profile with zero questions has nothing to answer, so
+# "needs_answers" is unsatisfiable and wrong: normalize it to ready.
+#
+# Scope: this ONLY resolves the needs_answers + 0-questions contradiction. The
+# independent confidence-floor gate (MINI_ORK_PLAN_CONFIDENCE_FLOOR) is untouched
+# — a genuinely low-confidence plan still blocks. Defines a pure function with no
+# top-level side effects, so it is safe to source early.

+# ── Synthesis-class promotion gate (Wave 1 D, oracle-hardening-v0.3) ─────────
+#
+# desc: Selective-feedback conjunction gate for synthesis-class task classes.
+#
+# The framework auto-promotes deterministic-oracle classes (code_fix,
+# db_migration) via promotion_evaluate above — the external verifier IS
+# the oracle. Synthesis classes (research_synthesis, refactor_audit,
+# blog-post, ui-audit, ops-runbook) lack such an oracle: their promotion
+# gate is LLM-judged by the same family distribution that produced the
+# candidate. Zenil 2026 (arxiv:2601.05280) proves this yields
+# degenerative dynamics in the limit.
+#
+# Adapala 2025 (arxiv:2509.10509) demonstrates the cheap remedy:
+# "Anti-Ouroboros" effect — a selective filter retaining only
+# candidates passing a quality threshold BEFORE re-ingest flips
+# collapse into emergent resilience. The selection step does the work
+# of a tiny oracle slice.
+#
+# This gate requires ALL THREE conditions to mark a synthesis candidate
+# auto-promote-eligible:
+#
+#   1. Panel rubric score >= MO_PROMOTE_SCORE_THRESHOLD (default 80)
+#   2. CW-POR <= MO_CW_POR_THRESHOLD (default 0.3) — no authority capture.
+#      Soft dep on lib/cw_por.sh: default-passes if the library is absent
+#      so this gate doesn't hard-depend on W1-C ordering.
+#   3. >= 1 independent structural quality signal:
+#        - citation_density_per_lens > MO_MIN_CITATION_DENSITY (default 3)
+#        - file_coverage_delta > 0
+#        - finding_cardinality > MO_MIN_FINDING_CARDINALITY (default 5)
+#
+# Conjunction beats single-signal: correlated failures across the LLM
+# panel are less likely to also fool the second independent structural
+# signal.
+#
+# Deterministic-oracle classes route through promotion_evaluate above
+# unchanged; this gate is the additive synthesis-class branch.
+#
+# Public API:
+#   mo_promote_synthesis_gate <panel_verdict.json> <task_class>
+#       → emits structured JSON: { decision, reason, signals: {...} }

+# cl_codex.sh — executable wrapper that adapts mini-ork's dispatcher
+# calling convention to the OpenAI Codex CLI shape.
+#
+# Why executable (not sourceable like cl_glm.sh / cl_opus.sh):
+# Codex isn't an Anthropic-compatible gateway — it's a separate CLI
+# with its own auth (~/.codex/config.toml) and its own invocation
+# pattern (`codex exec [PROMPT]`). The framework's lib/llm-dispatch.sh
+# dispatcher has TWO branches at mo_llm_dispatch:
+#
+#   - Sourceable (cl_glm/cl_kimi/cl_opus/cl_sonnet/cl_deepseek/cl_minimax):
+#     source the cl_*.sh in a subshell → env-vars pin claude's
+#     ANTHROPIC_BASE_URL/MODEL → invoke `claude --print --output-format
+#     text "$prompt"`.
+#
+#   - Executable (cl_codex / cl_gemini per _MO_LLM_EXECUTABLE_MODELS in
+#     lib/llm-dispatch.sh:54): call the cl_*.sh as a binary with the
+#     same `--print --output-format text "$prompt"` args; wrapper
+#     translates to native CLI shape.
+#
+# This wrapper IS the executable form for codex. It accepts the
+# dispatcher's flag dialect and emits the same shape of output (raw
+# text or JSON envelope) to stdout.
+#
+# Requires: `codex` CLI on PATH + ~/.codex/config.toml authenticated
+# (run `codex login` if not).
+#
+# v0.2-pt15 (D-049): closes the cl_codex.sh gap that made positioning
+# claim "codex_lens → codex" undeliverable. Validates by `mini-ork run
+# refactor-audit` or `research-synthesis` actually routing codex_lens
+# through this wrapper.

+# refute_or_promote_gate.sh — adversarial fabricated-bug injection oracle.
+#
+# Implements the Refute-or-Promote gate cited in the positioning-doc
+# calibration list (Agarwal 2026, arxiv:2604.19049). The unit measurement
+# question is: "does the validator actually distinguish real findings
+# from planted fakes?" A validator that confidently flags fabricated
+# bugs as real is hallucinating, regardless of how rigorous its review
+# prose sounds. This gate exposes that property mechanically.
+#
+# The full Refute-or-Promote pipeline is a recipe-level orchestration:
+#   1) generate N unique fabrication markers + record their identifiers,
+#   2) splice them into a corpus copy under fixed offsets,
+#   3) run the audit recipe on the modified corpus,
+#   4) parse the audit's findings list,
+#   5) count how many findings cite fabrication identifiers,
+#   6) compute FP-survival rate = fp_count / N,
+#   7) compare against MO_REFUTE_FP_CEILING.
+#
+# This file provides the two leaf primitives (1 and 5+6+7) and leaves
+# corpus mutation + audit dispatch to the caller, because those are
+# recipe-specific. The fabrication design is deliberately tractable:
+# each marker is a synthetic file path that does NOT exist in the repo,
+# paired with a synthetic claim. A validator that reads its citations
+# (citation_verifier_mechanical.sh shipped at 31f7808) will reject the
+# fake; a validator that hallucinates will accept it.
+#
+# Public API:
+#   mo_generate_fabrications <count> <out_json_path>
+#       Writes a JSON array of fabrication records:
+#         [{"id": "<short hex>",
+#           "path": "<fake path containing the id>",
+#           "line": <int>,

+#       rc=0 on success.
+#
+#   mo_check_fabrication_survival <findings_path> <fabrications_json> [<report_dir>]
+#       findings_path is a text or markdown file containing the audit's
+#       findings. Detection counts a fabrication as "survived" when its
+#       id token appears anywhere in the findings text — i.e., the
+#       validator cited the fake path as if it were real evidence.
+#       Emits JSON:

+# lib/repo_integrity_guard.sh — standing guard against cross-repo clobbers
+# of the current branch ref.
+#
+# Problem this solves: a foreign dispatch (codex sandbox cleanup, framework
+# edit, or rogue subagent) has been observed orphaning the current branch
+# tip onto an UNRELATED, OLDER commit. The post-commit watchdog
+# (.githooks/post-commit) catches this only when a local commit just
+# happened — there's a window (between commits, or when no commit ever
+# happened locally on this clone) where the clobber slips through.
+#
+# This guard runs on every mini-ork startup so the window collapses to
+# "next dispatch step". It is best-effort: a transient git error must
+# never abort the calling mini-ork run.
+#
+# Strategy:
+#   1. Resolve baseline SHA — priority:
+#        a. .mini-ork/last-known-good-ref.<branch> (preferred)
+#        b. origin/main  (fallback for fresh clones / no prior file)
+#        c. Most recent reflog entry for the branch (last-resort fallback)
+#   2. If no baseline exists  → cold start, just record current tip and exit.
+#   3. If baseline == current tip → up-to-date, re-record, exit.
+#   4. Two-condition clobber test (mirrors .githooks/post-commit lines 80-94):
+#        a. ! merge-base --is-ancestor <baseline> <tip>     (commit orphaned)
+#        b. tip_ct < baseline_ct                            (not a fresh amend)
+#      Both true → CLOBBER. Restore via `git update-ref` only — never the
+#      destructive git operations that mutate HEAD or the working tree;
+#      those are out of scope for a guard that runs on every startup.
+#   5. Otherwise → legitimate advance / fast-forward. Record new tip.
+#
+# Recovery log lives at .mini-ork/repo-integrity-guard.log (TSV):
+#   <iso-timestamp>\t<baseline>\t<old-tip>\t<action>

+#   MO_REPO_INTEGRITY_GUARD_DISABLED=1   → exit 0 immediately, no I/O.

+# at the same path inside the container. Real put/get cross the

+# Never abort a run because isolation is unavailable.
+#
+# Concurrency: the container-id lives at
+#   ${MINI_ORK_RUN_DIR:-/tmp/mo-runtime-docker-$$-$RANDOM}.cid
+# so ~29 simultaneous MO_RUNTIME_BACKEND=docker runs don't clobber each
+# other's cid (and don't accidentally `docker rm` a sibling container).

+# the panel-revised ordering at
+# docs/research/omnigent-vs-mini-ork-panel-synthesis.md.
+#
+# The 8-lens panel unanimously flagged secret isolation as the
+# highest-leverage gap (codex-1 verified the exfil path at
+# lib/llm-dispatch.sh:694-781). Omnigent ships a real OS sandbox
+# stack (bwrap on Linux at omnigent/sandbox/bwrap.py, seatbelt on
+# macOS at omnigent/sandbox/seatbelt.py). Both Apache 2.0.
+#
+# This bridge does NOT reimplement those backends — it shells out
+# to the omnigent CLI when installed and falls back to a clearly-
+# logged pass-through when not. Operators choose whether to install
+# Omnigent; mini-ork stays runnable either way.
+#
+# Public API:
+#   mo_sandbox_detect
+#       Emits backend identity on stdout:
+#         linux_bwrap | mac_seatbelt | omnigent_absent | unsupported
+#   mo_sandbox_run <command-array>
+#       Runs <command...> inside the resolved sandbox. When the
+#       sandbox CLI is absent, runs the command directly and logs
+#       a structured 'omnigent_unavailable' warning to stderr.
+#
+# Env knobs:
+#   MO_OMNIGENT_BIN   Override path to the omnigent CLI. Default:
+#                      `command -v omnigent`.

+#   - the dispatcher's plan-status gate (bin/mini-ork-execute) does the

+# A recipe signals a checkpoint by emitting plan_status=needs_steering in its
+# run_profile/plan. The gate then asks this library "is steering present yet?":
+#   - YES  → clear the checkpoint marker, proceed (the steering row is consumed
+#            by the next node's context_assemble),
+#   - NO   → write a .steering-checkpoint marker + JSON, pause the run.
+# The external driver (dashboard, product backend) sees the awaiting marker,
+# collects the human's steering, POSTs it to /api/v1/task-runs/<id>/steer, then
+# resumes the run — which re-evaluates the gate and now proceeds.

 """Python framework facade for mini-ork.
 
-Two public layers:
-
-* **Primitives** — in-process building blocks with no YAML and no subprocess:
-  execution-anchored verification (``Crucible``), heterogeneous model dispatch
-  (``dispatch_model``), verified-outcome memory (``memory``), and cost-free
-  bandit routing (``router`` / ``preferred_lane``). These run in your process
-  and return typed objects, so any application can embed them directly::
-
-      from mini_ork import Crucible, dispatch_model, memory, router
-
-* **Orchestrator** — the full classify -> plan -> execute -> verify lifecycle via
-  the ``MiniOrk`` client and the typed spec/request objects. It shells out to
-  the ``mini-ork`` CLI behind a stable ``--json`` result contract.
-
-The heavy primitive modules are imported lazily (PEP 562 ``__getattr__``) so
-``import mini_ork`` stays cheap and free of import cycles — you only pay for
-the dispatch/runtime/memory machinery when you actually reference it.
+The Python API is intentionally a facade over the existing mini-ork runtime:
+it gives integrators typed objects, extension hooks, and transparent run
+artifacts while preserving compatibility with the CLI/Bash engine.

-the cache and skips the LLM/verifier call.
-
-MIGRATION NOTE — win #2 (cross-iteration reuse):

-    inputs. This port drops ``iter`` from the MATCH predicate — it is still
-    stored for provenance — so a stable region is embedded once and reused
-    across iterations. The allowed ``stage`` set is also widened to include the
-    verifier tiers + panel so the loop's expensive nodes become cacheable.

-"""Python port of ``bin/mini-ork-apply`` + ``lib/apply.sh`` — close the apply
-loop (IMPL-3).
-
-Consumes the highest-confidence pattern_records / emergent_patterns /
-gradient_records row for a (task_class, target_kind, target_name) tuple,
-materializes it as a workflow_candidates row, scores it on a held-out set,
-and ONLY if the non-regression gate clears does it rewrite the target prompt
-file + write a version_registry entry. On regression it quarantines the
-candidate and writes a promotion_records row explaining the decision.
-
-Strangler-fig parity port. The bash implementation is already mostly inline
-``python3 - <<'PY'`` heredocs; this module lifts those blocks verbatim into
-functions and replaces the bash control flow (arg parsing, env exports,
-command substitution) with equivalent Python. CLI surface (flags, stdout/
-stderr contract, exit codes) matches ``bin/mini-ork-apply``.
-
-Public surface (mirrors the bash API one-for-one):
-
-    help_text()                          → bash `_usage` heredoc
-    ensure_tables(db=None)               → _apply_ensure_tables
-    pick_candidate(tc, tk, tn, db=None)  → apply_pick_candidate
-    score_candidate(cid, scorer=None)    → apply_score_candidate
-    evaluate_gate(cid, ub, ua,
-                  pertask_json="")       → apply_evaluate_gate
-    materialize_candidate(...)           → apply_materialize_candidate
-    apply_mutation(cid, target_file,
-                   new_prompt, db=None)  → apply_apply_mutation
-    attempt_record(...)                  → apply_attempt_record
-    record_promotion(...)                → apply_record_promotion
-    apply_run(tc, tk, tn,
-              target_file="", db=None)   → apply_run
-    main(argv=None)                      → bin/mini-ork-apply dispatcher
-
-Env contract (identical to bash):
-    MO_APPLY_ENABLED=1            master gate (default OFF)
-    MO_APPLY_DRY_RUN=1            skip file write + version_registry write
-    MO_APPLY_NONREGRESSION_DELTA  default 0.0
-    MO_APPLY_REGRESSION_TOLERANCE default 0 (strict per-task no-regression)
-    MO_APPLY_PERTASK_JSON         optional {"before":[...],"after":[...]}
-    MO_APPLY_MIN_EXAMPLES         default 1
-    MO_APPLY_SCORER               mock (default) | gepa
-    MO_APPLY_MOCK_BASELINE        mock baseline (score: 0.5; gate: 0.0)
-    MO_APPLY_MOCK_DELTA           mock delta (default 0.05)
-    MO_APPLY_FORCE_REGRESSION=1   test seam: forces a regression score
-    MINI_ORK_REQUIRE_HUMAN_APPROVAL=true  force pending_human_approval
-
-Exit code mapping (mirrors bash exactly):
-    0  success (promote, quarantine, and no_candidate all exit 0 — a
-       gate-driven quarantine is success: the gate ENFORCED itself)
-    1  missing flag value (bash `${2:?msg}` aborts with rc 1)
-    2  usage error (unknown flag, unexpected argument, missing --task-class
-       or --target)

-"""Python port of ``bin/mini-ork-bugs`` — operator CLI for the bug-report channel.
-
-Strangler-fig parity port of the 42-line bash dispatcher. The bash script
-stays in place (strangler-fig KEEP invariant per the migration kickoff);
-this module gives Python callers an in-process target and gives the parity
-test a stable surface to byte-diff against the live bash subprocess.
-
-Pipeline map (bash subcommand → Python dispatch):
-  sweep                 → bug_report_sweep      (delegates to mini_ork.observability.bug_report)
-  list                  → bug_report_list       (delegates)
-  show <id>             → bug_report_show       (delegates)
-  prioritize [--top N]  → bug_report_prioritize (delegates)
-  promote --top N       → bug_report_promote    (delegates)
-  help|--help|-h        → _usage()              (hand-mirrored literal)
-  <other>               → stderr msg + _usage + exit 2
-
-Env resolution (mirrors bash bin/mini-ork-bugs lines 19-23):
-  * ``MINI_ORK_ROOT``  — repo root for promote kickoff files; default is the
-    parent of the ``mini_ork`` package, resolved via ``Path.resolve()`` which
-    canonicalizes symlinks (mirrors bash ``readlink -f``).
-  * ``MINI_ORK_HOME``  — runs root for sweep; default ``$MINI_ORK_ROOT/.mini-ork``.
-  * ``MINI_ORK_DB``    — state.db path; default ``$MINI_ORK_HOME/state.db``.
-
-Output semantics:
-  * ``sweep`` / ``promote`` return a count integer from the peer; the
-    dispatcher writes ``"<n>\\n"`` to stdout, matching bash's ``print(N)``.
-  * ``list`` / ``prioritize`` / ``show`` forward peer stdout byte-for-byte.
-  * ``help`` / ``--help`` / ``-h`` write ``_USAGE_BLOCK`` to stdout.
-  * Unknown subcommand writes ``Unknown subcommand: <x>\\n`` to stderr,
-    then ``_USAGE_BLOCK`` to stdout, then exits 2 (matches bash case `*`).
-
-Parity is enforced by ``tests/unit/test_mini_ork_bugs_py.py`` (>=6 cases
-that drive the LIVE bash subprocess against a temp DB seeded by
-``db/init.sh`` and diff stdout/stderr/exit-code against the Python port
-byte-for-byte; floats 1e-6 on confidence; epochs 1-second tolerance).
-
-Bash source-of-truth: ``bin/mini-ork-bugs`` lines 2-16 (extracted by bash
-``_usage()`` via ``sed -n '2,16p' "$0" | sed 's/^# \\{0,1\\}//'``). The
-literal below is hand-mirrored; ``test_help_parity`` re-verifies it on
-every CI run so any drift in the bash docblock is caught immediately.

-"""mini_ork_eval — Python port of ``bin/mini-ork-eval``.
-
-Faithful port of the bash entry point that evaluates a workflow candidate
-against the benchmark suite and emits ``utility_delta`` on stdout. Re-uses
-``mini_ork.learning.benchmark_suite`` so we don't re-port that surface.
-
-The bash script (bin/mini-ork-eval) is the authoritative source; this
-module gives Python callers an in-process target and gives
-``tests/unit/test_mini_ork_eval_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Co-existence model (strangler-fig): ``bin/mini-ork-eval`` stays
-byte-identical. The python port mirrors the embedded stdout/stderr
-block-for-block — same 14-line usage block, same ``=== mini-ork eval ===``
-header/footer, same ``tasks_evaluated: 0 / total_utility: 0 /
-baseline_utility:0 / utility_delta:   0`` lines, same trailing
-``utility_delta=0`` line, same 4-line "Candidate not found" stderr,
-same PRAGMA-WAL UPDATE heredoc into ``workflow_candidates``. Parity
-is enforced by the sibling test (8 live-subprocess cases, floats
-within 1e-6, stdout bytes-equal, DB row-diff zero on stable columns).
-
-Latent bash bug preserved (parity-required): bash's
-``_eval_result_cb`` is shell-internal and never crosses the
-bash→python boundary. Concretely:
-  * ``benchmark_run`` has no flag parsing — it always takes ``$1``
-    as ``candidate_id`` and ignores ``--suite``/``--candidate-id``/
-    ``--workflow-file``/``--executor``/``--on-result-callback``.
-  * ``utility_compute`` / ``utility_baseline`` are called by the
-    callback but do not exist in ``lib/utility_function.sh``.
-  * The callback never fires, so ``TOTAL_UTILITY`` /
-    ``BASELINE_UTILITY`` / ``TASK_COUNT`` are always ``0`` in bash,
-    and ``utility_delta`` is always ``0``.
-
-The python port mirrors that literal behaviour — total_utility=0,
-baseline_utility=0, task_count=0, utility_delta=0 every non-dry-run.
-``benchmark_suite.run`` is still called (to mirror the bash side-effect
-of writing a synthetic epic + runs row + benchmark_results rows) but
-its return value is discarded because the bash callback that would
-have populated TOTAL/BASELINE/TASK_COUNT never fires.
-
-DB resolution: bash reads ``${MINI_ORK_DB:-${MINI_ORK_HOME}/state.db}``
-with env > cwd fallback. The port mirrors that exact order — env wins,
-then ``$MINI_ORK_HOME/state.db``, then ``cwd/.mini-ork/state.db``.

-
-    mini_ork.dispatch.routing     — lane fallback chains + routing policy registry

-"""Pure-logic port of ``bin/mini-ork-init``.
-
-Faithful Python port of the ``.mini-ork/`` scaffolder: creates the
-home directory tree, seeds ``config/task_classes/`` from every recipe's
-``task_class.yaml``, copies ``agents.yaml`` and ``scope-patterns.yaml.example``
-into ``config/``, builds ``state.db`` via the native Python migration runner
-(``mini_ork.stores.migrate.init_db``, the db/init.sh port), and
-appends the canonical ``.gitignore`` entries to the project root's
-``.gitignore``. Idempotent on re-run.
-
-Strangler-fig co-existence: ``bin/mini-ork-init`` is byte-identical
-before and after this module exists. ``tests/unit/test_mini_ork_init_py.py``
-is the parity gate that proves the port produces byte-identical stdout
-and filesystem state (including ``state.db`` row content within 1e-6
-float tolerance) against the live bash subprocess (no mocking).

-"""Native implementation of the ``mini-ork-invoke-prompt`` utility.

-Bash-side contract this port mirrors (verbatim from bin/mini-ork-invoke-prompt):

-    MINI_ORK_NODE_TYPE (default "implementer"), MINI_ORK_TASK_CLASS (default
-    "generic"), MINI_ORK_ROOT (default = repo root, two parents up from the
-    script). MINI_ORK_RECIPE / MINI_ORK_RUN_ID are advisory (read by trace).
-  - Placeholder substitution: {{[A-Z][A-Z0-9_]*}} -> os.environ[name]; missing
-    var leaves the token verbatim (matches bash's `os.environ.get(name,
-    match.group(0))` heredoc).
-  - LLM dispatch is owned by ``mini_ork.dispatch.llm_dispatch``; trace writes
-    go through the native ``mini_ork.trace_store.trace_write`` (bash
-    ``lib/trace_store.sh`` retired at this call site).
-  - Exit codes: 0 success, 1 llm-failure, 2 bad-args (prompt file missing OR
-    env var unset).
-  - Output: bash's `RESPONSE=$(... 2>&1)` strips trailing newlines, then
-    `printf '%s\\n' "$RESPONSE"` adds one back. This port mirrors via
-    `response.rstrip('\\n') + '\\n'` so multi-newline LLM outputs remain
-    byte-equal across backends.
-  - Stderr merging: the native dispatcher's stdout and stderr are redirected
-    to the same buffer, preserving the former shell ``2>&1`` contract.

-"""Sole runtime implementation of the mini-ork reflect command.
-
-Mirrors the bash CLI byte-for-byte: same flags, same stdout/stderr lines,
-same env-var opt-out toggles (MO_PATTERN_MINER, MO_CROSS_EPIC_GRADIENTS,
-MO_BUG_REPORT_SWEEP, MO_RHO_AGGREGATE, MO_LANE_ROUTER), same SQLite writes.
-
-This module owns the CLI surface and dispatches
-the load-bearing pipeline call (`reflection_run`) to the ported Python
-implementation in `mini_ork.learning.reflection_pipeline`. The rho aggregator,
-lane router, trace-store writes, pattern-store, cross-epic-gradient, and
-bug-report side channels are all native now (bash side-channel libs retired).
-Parity is enforced by
-`tests/unit/test_mini_ork_reflect_py.py` (eight standalone golden and
-behavioral contracts captured after pre-retirement byte parity passed).
-
-GEPA optimizer block (MO_OPTIMIZER=gepa) is intentionally NOT ported: the
-default path (MO_OPTIMIZER unset) leaves the block fully skipped, which
-matches the kickoff's "byte-identical to the pre-R4b reflect" invariant.

-"""Python port of ``bin/mini-ork-resume``.

-``MO_PAUSE_EVERY_USD``. This entrypoint removes the sentinel and records
-the approval to ``<run_dir>/.cost-pause-approvals.jsonl`` so the resume

-The bash script at ``bin/mini-ork-resume`` is the live reference; this

-called in-process by tests and other modules without forking a shell.
-Parity is enforced by ``tests/unit/test_mini_ork_resume_py.py`` which

-"""Python port of ``bin/mini-ork-rollback`` — thin CLI over
-``mini_ork.registries.version_registry.rollback``.
-
-Strangler-fig parity port. The bash script is a thin wrapper that parses
-two positional args (``kind`` and ``name``), validates them, then delegates
-to ``version_rollback`` from ``lib/version_registry.sh``. The Python port
-mirrors that role: it re-parses the same arguments, applies the same
-validation, and delegates to the already-ported
-``mini_ork.registries.version_registry.rollback``. Argument parsing, exit
-codes, help text, and stderr routing all match the bash source
-byte-for-byte so the parity test (``tests/unit/test_mini_ork_rollback_py.py``)
-can compare live bash invocations against this module on the same
-temp DB.
-
-Public surface (mirrors bash functions / arg flow):
-
-    help_text()              → bash `_usage` heredoc block
-    rollback(kind, name,
-             db=None, now=None)
-                              → version_registry.rollback (delegates)
-    main(argv=None)          → CLI dispatcher (exit codes mirror bash)
-
-Exit code mapping (mirrors bash exactly):
-
-    0  success — JSON of the now-stable previous version on stdout.
-    2  usage error — bash emitted `_usage` to stderr (invalid kind,
-       missing name, or wrong arg count). Python mirrors by writing
-       HELP_TEXT to stderr.
-    1  rollback failure — ``version_rollback`` itself failed (no stable
-       found, or stable has no ``previous_stable_version``). The
-       bash heredoc's ``sys.exit(1)`` propagates through the function
-       call and ``set -e`` exits the script with 1. Python catches the
-       ValueError raised by the Python port of ``version_registry.rollback``
-       and emits ``str(e)`` to stderr (matches bash's stderr verbatim).
-
-Environment honored:
-
-    MINI_ORK_DB        — state.db path (used when ``db=None``).
-    MINI_ORK_HOME      — base dir for the default DB path
-                         (only when ``db=None`` AND ``MINI_ORK_DB`` unset).
-    TZ                 — pinned in parity tests to ``UTC`` so any
-                         ``datetime(..., 'localtime')`` comparison
-                         doesn't drift. The rollback SQL itself does
-                         not format datetimes — only ``int(time.time())``
-                         epoch seconds — but TZ is still propagated
-                         for consistency with other parity tests.
-
-Parity is enforced by ``tests/unit/test_mini_ork_rollback_py.py``
-(>=6 cases that drive the LIVE ``bin/mini-ork-rollback`` bash subprocess
-against a temp DB seeded by ``db/init.sh`` and compare stdout / stderr /
-exit codes against this module).

-"""Python port of bin/mini-ork-serve — boot the local observability UI.

-Strangler-fig parity port of the launcher. The server itself is already Python
-(``mini_ork.web.app:app``); this replicates the bash entrypoint's arg parsing,
-preflight checks (state.db present, fastapi+uvicorn importable), and the final
-``uvicorn`` exec. Returns an int rc (like the bash exit codes) so it's testable
-without actually binding a port; ``run_server`` is split out so tests can assert

-Options:
-  --port N      HTTP port (default 7090)

-"""Python port of bin/mini-ork-spawn — bounded child mini-ork orchestrator.
-
-Faithful port of the bash CLI wrapper that approves + (optionally) executes a
-bounded child mini-ork. Co-existence model (strangler-fig): bash
-`bin/mini-ork-spawn` remains the authoritative source. This module mirrors
-its observable surfaces exactly:
-
-    spawn_id=…
-    parent_run_id=…
-    child_run_id=…
-    child_workspace=…
-    child_kickoff=…
-    depth=N
-    allow_child_spawn=0|1
-    spawn_status=approved|completed|failed
-
-Plus identical DB rows in `run_spawns`, `run_events`, and `task_runs` (floats
-1e-6 on `authority_level`; epochs within 1s tolerance; `spawn_id`/`event_id`
-stem-equal because the random hex12 suffix is generated per port).
-
-DB writes are delegated to `mini_ork.orchestration.recursive` (the
-port of `lib/recursive_orchestration.sh`). The Python port does NOT inline
-SQLite writes; it composes the recursive_orchestration helpers so that DB
-parity vs bash is enforced once at that layer's parity test.
-
-The execute path shells out to `bin/mini-ork` subprocess (the real CLI), so
-the port does not duplicate the child run engine. The `MINI_ORK_ROOT` env var
-locates the CLI binary; falls back to the directory above this file.
-
-Usage:
-    from mini_ork.cli import spawn as mini_ork_spawn
-    rc = mini_ork_spawn.main(["--parent-run", "p1", "--kickoff", "/tmp/k.md",
-                              "--child-run", "c1", "--no-execute"])

-"""Python port of ``bin/mini-ork-topology`` — query + compute panel-topology telemetry.
-
-Faithful port of the E-MO-01 operator CLI ``bin/mini-ork-topology``. The
-bash entrypoint sources ``lib/topology_metrics.sh`` and exposes three
-subcommands (default summary, ``--compute <panel_run_id> <recipe>``, and
-``--backfill``). This module mirrors the same subcommand surface via
-``main(argv=None)`` so callers (including the parity test) can drive it
-both as a CLI (``python -m mini_ork.cli.topology …``) and
-as an importable library.
-
-Public API (mirrors the bash CLI 1:1)::
-

-Co-existence model (strangler-fig): ``bin/mini-ork-topology`` stays
-byte-identical; the Python port is invoked independently. Parity is
-enforced by ``tests/unit/test_mini_ork_topology_py.py`` (six
-live-subprocess parity cases; floats within 1e-6; ``sqlite3 -box``
-output diffed as parsed row dicts to insulate from column-width drift).
-
-The bash script's ``measure_*`` calls shell out to inline ``python3 -``
-heredocs. The port inlines the peer module
-:func:`mini_ork.observability.topology_metrics.{measure_rho, measure_C,
-measure_I, measure_topology}` and calls them directly — no bash
-subprocess required for measurement, only for the parity test's own
-comparison invocation.
-
-Output format notes (kept verbatim so the parity test can grep on
-literal banner text):
-
-  * ``--compute`` emits 8 lines:
-        ``=== mini-ork topology — ad-hoc measurement ===``
-        ``    panel_run_id: <id>``
-        ``    recipe:       <recipe>``
-        ```` (blank)
-        ``    rho:   <float>``
-        ``    C:     <float>``
-        ``    I:     <float>``
-        ```` (blank)
-        ``Persisting to panel_topology_telemetry...``
-        ``telemetry_id=<id>``
-    The em-dash is U+2014 (``\\u2014``); bash emits the same character
-    via UTF-8 source. Tests parse this banner into named fields rather
-    than asserting raw string equality to keep parser tolerance tight.
-
-  * ``--backfill`` emits the banner then ``<prid> → <recipe> →
-    <telemetry_id>`` per row, ending with ``Backfilled N panel_runs.``.
-
-  * Default ``summary`` mode shells out to ``sqlite3 -box`` with the
-    same SQL body as bash, then a second ``sqlite3 -box`` for the
-    quadrant distribution. Both ports round-trip through the same
-    ``sqlite3`` binary so column widths match; the parity test parses
-    rows by ``|``-boundary splits.

-"""mini_ork/cli/update — Python port of bin/mini-ork-update.
-
-Bash-side contract this port mirrors (verbatim from bin/mini-ork-update):
-  - Inputs (positional argv): --dry-run, --pull, --help/-h. Unknown option → rc=2
-    + 'Unknown option: X' + usage on stderr.
-  - Env resolution (in priority order):
-      MINI_ORK_ROOT  : framework checkout; defaults to 2 parents up from the
-                       script (bin/.. → repo root). For this Python port the
-                       equivalent is parents[2] of mini_ork/cli/.
-      MINI_ORK_HOME  : project's .mini-ork/; defaults to <cwd>/.mini-ork.
-      MINI_ORK_DB    : state.db path; defaults to <MINI_ORK_HOME>/state.db.
-  - Subprocess delegation (strangler-fig — bash is single source of truth):
-      * git pull sequence  → `git -C "$ROOT" …` via subprocess.run (3 calls)
-      * sqlite3 schema check → native Python sqlite query (ported from the
-        bash `sqlite3 file:DB?mode=ro | grep -qx 1` one-liner)
-      * migration apply    → `mini_ork.stores.migrate.init_db` (native Python
-        port of db/init.sh; stdout/stderr re-emitted byte-identically)
-  - Output bytes MUST match bash. The [OK]/[WARN]/[FAIL] status helpers, the
-    per-line spacing ('  [OK]   ' vs '  [WARN] ' / '  [FAIL] ' — three spaces
-    vs one space), the '           suggested: …' followups (11 leading spaces),
-    and the trailing summary block are all part of the byte-equality surface
-    that the parity test asserts.
-  - Exit codes: 0 success (FAIL count == 0), 1 failure (missing home, dirty
-    git checkout, db/init.sh non-zero, or summary FAIL>0), 2 unknown option.

-"""Canonical run-context and environment contract for the mini-ork runtime.
-
-Historically the runtime communicated across layers by reading and mutating
-``os.environ`` ad hoc (766 references across the package). This module is the
-single source of truth for that contract:
-
-- ``RunContext`` names the run-identity variables (``MINI_ORK_*``) as typed
-  fields, with ``from_env`` / ``as_env`` / ``apply`` converting between the
-  dataclass and the process environment in one tested place.
-- ``node_env_overrides`` names the per-node dispatch variables (``MO_*``) the
-  executor publishes before a node runs.
-- ``apply_env_overrides`` / ``scoped_environ`` are the only sanctioned ways to
-  mutate process env: overrides are explicit mappings where ``None`` means
-  "remove", and ``scoped_environ`` restores prior state for scopes that must
-  not leak.
-
-Behavioral note: several consumers (in-process ``dispatch_fn`` seams, the
-provider layer, and parity tests) intentionally read ``os.environ`` *during*
-dispatch, so the executor still publishes these variables process-wide rather
-than passing them purely as parameters. What changes is that the contract is
-declared once, here, instead of being re-derived at every call site.

-"""Native Python port of ``lib/providers/cl_codex.sh`` (bash-removal WS6).
-
-Drop-in replacement for the executable codex wrapper, invoked exactly like it::
-
-    python3 -m mini_ork.dispatch.codex_transport --print --output-format text "$prompt"
-
-The prompt is also accepted on stdin (no positional arg + non-tty stdin), which
-is how ``mini_ork.dispatch.core.dispatch`` drives it (E2BIG-proof end to end).
-
-Contract ported faithfully from the bash wrapper:
-
-  - arg dialect: ``--print`` / ``--permission-mode`` / ``--max-turns`` /
-    ``--exclude-dynamic-system-prompt-sections`` accepted + ignored (claude
-    compat); ``--output-format text|json``; any other ``-*`` flag ignored;
-    first positional is the prompt. No prompt → stderr + rc 2.
-  - ``codex`` CLI missing from PATH → stderr + rc 3.
-  - BYO endpoint: ``MO_OAI_BASE_URL`` + ``MO_OAI_ENV_KEY`` set → the named key
-    var must be non-empty (else stderr + rc 5); passes
-    ``-c model_providers.mini_ork={...wire_api="chat"}`` +
-    ``-c model_provider=mini_ork``; ``MO_OAI_MODEL`` → ``-m``.
-  - cwd: ``MO_TARGET_CWD`` → ``MINI_ORK_TARGET_REPO`` → process cwd; the
-    framework-tree guard (``bin/mini-ork`` present, or a path matching the
-    bash ``*/.mini-ork`` / ``*/mini-ork`` patterns) refuses with stderr + rc 2
-    unless ``MO_ALLOW_FRAMEWORK_CWD=1``; ``-C <dir>`` only when the dir exists.
-  - env hardening: ``GIT_TERMINAL_PROMPT=0``, ``GIT_ASKPASS`` /
-    ``SSH_ASKPASS=/bin/false``, batch-mode ``GIT_SSH_COMMAND`` (setdefault
-    semantics only).
-  - stream sidecar: ``${MO_USAGE_FILE%.tokens}.stream.jsonl`` when
-    ``MO_USAGE_FILE`` is set, else a mktemp file; the two launch lines are
-    written first; ``MO_CODEX_STREAM_FILE`` is exported.
-  - invoke: ``codex exec --skip-git-repo-check --sandbox ${CODEX_SANDBOX:-
-    workspace-write} --json --output-last-message <tmp> [-C cwd] [BYO flags]
-    -- "$PROMPT"`` with stdin from /dev/null and stdout+stderr appended to the
-    stream file. rc != 0 → stderr lines + rc 4.
-  - harvest: thread.started → thread_id; turn.completed → usage sums + turns;
-    writes ``MO_USAGE_FILE`` TSV, ``MO_TURNS_FILE`` jsonl, ``MO_COST_FILE``
-    cost at rates: ``MO_CODEX_USD_PER_MTOK_{IN,CACHED,OUT}`` env override →
-    pricing.yaml lookup (openai gpt-5 input/cache_read/output, via
-    :mod:`mini_ork.dispatch.pricing_strategy`) → defaults 1.25/0.125/10.0.
-  - body: ``--output-last-message`` content when non-empty, else reconstructed
-    from ``item.completed`` ``agent_message`` events joined with ``\\n\\n``;
-    the transcript envelope is stripped (text after the final bare ``codex``
-    line; status-line regexes dropped). Empty clean → raw fallback.
-  - output: ``--output-format json`` → claude-shaped envelope
-    ``{"result", "total_cost_usd": 0.0, "model": "codex"}``; else clean text.

-"""Pure-logic port of ``lib/config_resolve.sh``.
-
-Faithful port of the per-run config isolation pattern (roadmap T1.0):
-each run FREEZES its launch-time lane policy by snapshotting the
-global agents.yaml into ``run_dir/config/`` at launch, and every
-dispatch-time resolver reads ``run_dir/config/`` FIRST. This is the
-first concrete slice of the actor-per-run isolation epic — a design
-pattern (not a band-aid) that survives the Bash→Python migration.
-
-Strangler-fig co-existence: ``lib/config_resolve.sh`` is byte-identical
-before and after this module exists.
-``tests/unit/test_config_resolve_parity.py`` is the gate that proves the
-port produces byte-identical stdout and filesystem state against the
-live bash subprocess (no mocking).
-
-Public API::
-

-"""Lane-helpers — Python port of ``lib/lane-helpers.sh``.
-
-Faithful Python port of the six bash functions in
-``lib/lane-helpers.sh`` (lane predicate, budget flag, cache flag,
-capability assertion, cache-stats aggregation, claude --print wrapper).
-The bash source is the authoritative spec and stays byte-identical
-(strangler-fig invariant); this module gives Python callers an
-in-process target and gives ``tests/unit/test_lane_helpers_py.py`` a
-stable surface to byte-diff against the LIVE bash subprocess (no mocks,
-no hardcoded outputs).
-
-Co-existence model (strangler-fig): ``lib/lane-helpers.sh`` is not
-modified by this port. The Python port mirrors its CLI semantics
-exactly. Parity is enforced by
-``tests/unit/test_lane_helpers_py.py`` (>=6 live-bash-subprocess cases
-that drive ``bash lib/lane-helpers.sh <op>`` / ``bash -c '. … && mo_<op>'``
-on identical inputs and diff the resulting flags, stderr, exit codes,
-and cache-stats.json byte-for-byte).
-
-Pipeline map (bash function → Python):
-  mo_lane_is_free(lane)              → lane_is_free(lane) -> bool
-  (case glm|kimi|minimax)            (frozenset of free lanes)
-  mo_emit_budget_flag <arr> …        → emit_budget_flag(lane, val) -> list[str]
-  (local -n; out=(--max-budget-usd …)) (returns [] when free, [flag, val] when paid)
-  mo_emit_cache_flags <arr>          → emit_cache_flags() -> list[str]
-  (one-shot claude --help probe +     (module-level _CACHE_FLAG_SUPPORTED var;
-   _MO_CACHE_FLAG_SUPPORTED env var)  one-shot probe via _PROBE_DONE flag)
-  mo_assert_lane_capability <lane>   → assert_lane_capability(lane) -> None
-  (heredoc python3; stderr <cap>)    (raises RuntimeError(<cap>); reuses
-                                       mini_ork.dispatch.config_resolve
-                                       for yaml path resolution; same
-                                       external observable)
-  mo_aggregate_cache_stats <dir>     → aggregate_cache_stats(iter_dir) -> dict
-  (grep -oE + jq -n to write JSON)   (Python regex + json.dumps to

-"""Pure-logic port of ``lib/pricing_strategy.sh::pricing_lookup``.
-
-Faithful port of the deterministic lookup core of ``pricing_lookup``. The
-bash function is a thin shell that resolves ``MO_PRICING_YAML`` (with a
-``MINI_ORK_HOME`` fallback), checks for ``python3`` + ``PyYAML``, and
-otherwise delegates to an embedded Python heredoc that walks
-``pricing[provider][model][kind]``. This module lifts that walk into a
-regular import, strips the I/O + env + stderr layers (the test layer owns
-I/O), and exposes a single ``lookup(data, provider, model, kind)`` entry
-point.
-
-Public API::
-
-    from mini_ork.dispatch.pricing_strategy import lookup, ALLOWED
-
-    rate = lookup(data, "anthropic", "claude-sonnet-4-6", "input")
-    # -> "3.0"      # str() of the YAML-parsed rate, identical to bash
-
-``data`` is the parsed YAML document (typically ``yaml.safe_load(path)``).
-The port performs no I/O, reads no env, emits no stderr — every miss path
-returns ``"0"`` (the literal two-character string), matching bash's
-``print("0")`` after its stderr warning. Callers needing the file/env
-wrapping should invoke the bash function directly.
-
-``tests/unit/test_pricing_strategy_parity.py`` enforces byte-exact stdout
-parity between this module and the live bash subprocess over a fixture
-corpus of ``>=6`` cases.
-
-Parity contract (mirrors bash verbatim):
-    - kind not in ALLOWED -> "0"
-    - any of ``data``, ``data['pricing']``, the provider block, the model
-      block, or ``kind`` value missing/wrong-type -> "0"
-    - on hit, returns ``str(value)`` where ``value`` is whatever
-      ``yaml.safe_load`` produced (int stays int-repr, float stays
-      float-repr, str stays str)
-    - no exceptions escape; ``lookup`` never raises on malformed data
-      shape — it degrades to ``"0"`` so callers can compare to bash's
-      warning-then-``0`` behavior at the stdout level.

-"""Retention helpers for run_artifacts (kickoff feat/run-artifacts-store).

-Two functions, both best-effort and idempotent:
-
-  - :func:`gzip_run_stream` walks ``$MINI_ORK_RUN_DIR``, gzips every
-    ``agent-*.stream.jsonl`` to ``agent-*.stream.jsonl.gz``, and rewrites the
-    matching ``run_artifacts`` row's rel_path/sha256/bytes to the .gz file.
-
-  - :func:`prune_old_trajectories` deletes ``run_artifacts`` rows whose kind
-    is the per-call ``turn_jsonl`` and whose ``created_at`` is older than the
-    TTL (default 30 days), removing the matching ``.gz`` files from disk too.
-    Rows with kind ``evidence_bundle`` / ``transcript`` (or any other derived
-    kind) are NEVER pruned — those are the durable audit trail.
-
-Both functions no-op (return 0) when the ``run_artifacts`` table is absent or
-the run dir / DB doesn't exist. The DB is gated with the same PRAGMA-table
-introspection used by :mod:`mini_ork.dispatch.telemetry`, so old DBs keep
-working without the migration.

-"""adaptive_stability — Python port of lib/adaptive_stability.sh.
-
-Faithful port of ``mo_check_panel_stability`` — the early-termination
-signal for multi-round panel debate (Hu et al 2025, arxiv:2510.12697).
-The bash script is the authoritative source; this module gives Python
-callers an in-process target and gives
-``tests/unit/test_adaptive_stability_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Co-existence model (strangler-fig): ``lib/adaptive_stability.sh`` stays
-byte-identical. This port mirrors the embedded Python heredoc exactly —
-same query, same round-bucketing regex, same fail-open reasons, same
-two-site ``round(.., 4)`` rounding, same decision order and rationale
-strings. Parity is enforced by the sibling test (>=6 live-subprocess
-cases; floats within 1e-6, strings/bools equal).
-
-Contract map (bash heredoc → Python):
-  SELECT ... WHERE trace_id LIKE %pid% OR tr-%-pid%   → _fetch_rows
-  re.search(r"-r(\\d+)-", trace_id)                    → round bucketing
-  verdict = (reviewer_verdict or verifier_output or "").strip().lower()
-                                                        → per-row verdict

-"""ArtifactContract loader + validator — Python port of lib/artifact_contract.sh.
-
-Faithful, line-by-line port of the deterministic core. The bash stays
-authoritative (strangler-fig co-existence); this module gives Python callers +
-pytest an in-process target. Parity is verified by
-``tests/unit/test_artifact_contract_py.py`` which invokes the live bash via
-subprocess and asserts byte/JSON-identical output for >=6 cases including one
-DB-coupled case seeded by ``db/init.sh``.
-
-Pipeline map (bash function → Python):
-  artifact_contract_load <task_class>            → load_contract(task_class, ...)
-  artifact_contract_validate <tc> <artifact>     → validate_artifact(contract,
-                                                            artifact_path, ...)

-        validate,                # -> (verdict_str, payload_dict)
-    )
-
-Output shape mirrors the bash's stdout:
-  load:    "{json}\n"
-  validate: "{pass|fail}\n{json}\n"
-
-Note on parity: no floats are emitted, so exact-string JSON comparison is the
-right gate (1e-6 tolerance is a no-op for this module but kept in this
-docstring per the kickoff's verifier requirement).
-
-Forward compatibility: any new ``expected_artifact_type`` enum value must be
-mirrored in BOTH ``lib/artifact_contract.sh`` AND this module. The port must
-NOT silently accept new types only on one side.

-"""Python port of ``lib/citation_verifier_mechanical.sh::mo_check_citations``.
-
-Recall-floor + wireheading check on synthesized documents. Extracts every
-``path:LINE`` (or ``path:START-END``) citation, verifies each resolves to
-a real file with the cited line range in bounds, computes a coverage ratio,
-and gates on a recall floor. Mirrors the bash semantics byte-stable so the
-parity test in ``tests/unit/test_citation_verifier_mechanical_py.py`` can
-diff live-bash vs ported-Python output at 1e-6 float tolerance.
-
-Public API:
-    ``check_citations(doc, report_dir=None, root=None, floor=None, min_count=None)``
-    returns ``(verdict_dict, rc)``. Same dict shape bash emits on stdout; same
-    rc semantics (``rc=0`` when gate cannot measure or coverage >= floor;
-    ``rc=1`` when ``CITATION_UNDERCOVERED`` triggers).
-
-Env knobs honored (overridable via kwargs):
-    ``MO_CITATION_COVERAGE_FLOOR``  default 0.8
-    ``MO_CITATION_MIN_COUNT``       default 3
-    ``MINI_ORK_ROOT``               default = parent of ``lib/`` (this module's

-"""Mini-ork gate bootstrap — Python port of lib/gates_common.sh.
-
-Faithful port of the bash ``mo_grounded_rejection`` helper required on every
-gate fail/needs_revision verdict per HarnessBridge Technique 4
-(arxiv:2606.12882) and the 2026-06-15 audit Theme C finding. The reflector
-reads structured rows from ``grounded_rejections`` (per
-``db/migrations/0037_grounded_rejection.sql``) instead of re-extracting tuples
-from free-text rationale.
-
-Public API mirrors ``lib/gates_common.sh`` exactly:
-    tuple_json(concern, evidence, suggestion) -> str
-    emit(gate, verdict, concern, evidence_summary, suggestion,
-         evidence_trace_ids='[]', run_id=None) -> str | int
-
-Return-value contract (matches bash):
-    tuple_json → JSON string on success; raises ValueError on missing required
-                 args (bash returns rc=2 in that case).
-    emit       → hex id (str) on success; rc (int: 2/3/0) on failure.
-                 rc=2 argument error, rc=3 JSON validation error, rc=0 success
-                 OR table-absent no-op.
-
-Strangler-fig note: this co-exists with lib/gates_common.sh; the bash file is
-not modified by the port. The Python side uses sqlite3 ``?`` parameter binding
-instead of bash's triple-quoted heredoc, so it's stricter against input but
-the observable row content is identical to a successful bash emit.

-"""coord_gate — Python port of lib/coord_gate.sh.
-
-Faithful port of the PreToolUse-style coordination gate: the public bash API
-(``coord_gate_check`` / ``coord_gate_metrics`` / ``coord_gate_metrics_field`` /
-``coord_gate_audit`` / ``coord_gate_record_deadlock`` /
-``coord_gate_record_ttl_expiration``) plus the internal bump / audit /
-observe / probe helpers. Mirrors the embedded Python heredocs inside
-``lib/coord_gate.sh`` exactly — same flock semantics, same default schema,
-same snapshot-vs-delta counter split.
-
-Co-existence model (strangler-fig): ``lib/coord_gate.sh`` stays
-byte-identical. This port gives Python callers an in-process target and
-gives ``tests/unit/test_coord_gate_py.py`` a stable surface to diff against
-the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Env knobs (bash reads these at function entry; the Python port takes them as
-explicit kwargs so callers/tests can pin them — the parity test passes the
-same values it exports to the bash subprocess). Reading happens at function
-entry, NOT at import time — matches bash semantics:
-
-  COORD_GATE_MODE               → mode_override     (default "advisory")
-  COORD_GATE_SCOPE              → scope_override    (default "/")
-  COORD_GATE_METRICS_FILE       → explicit metrics path override
-  COORD_GATE_AUDIT_FILE         → explicit audit path override
-  COORD_GATE_AUDIT_MAX          → audit_max         (default 64)
-  COORD_REGISTRY_STATE_FILE     → registry state file (skip fallback chain)
-  MINI_ORK_RUN_DIR              → state base dir (run-scoped override)
-  MINI_ORK_HOME                 → state base dir (user override)
-  HOME                          → ~/.mini-ork fallback
-
-Two exit-code paths preserved verbatim from bash:
-  rc=0   advisory path (with nudge on conflict, or no conflict)
-  rc=11  strict deny (path inside COORD_GATE_SCOPE)
-  rc=2   usage / argument validation failure

-"""Confidence-Weighted Persuasion Override Rate diagnostic — Python port of
-``lib/cw_por.sh``.
-
-Faithful port of the bash function ``mo_compute_cw_por``. Mirrors:
-
-  * file-existence validation + ``.voters[]`` shape validation (raises
-    ``FileNotFoundError`` / ``ValueError`` to mirror bash ``rc=2`` + stderr)
-  * the indeterminate branch (all voters have ``ground_truth_match=None``)
-  * the ``Counter.most_common(1)`` panel-adoption proxy on ``approve|reject``
-    votes
-  * the pairwise (correct, wrong) loop with confidence-delta overrides
-  * threshold-anchored verdict + rationale templating
-  * float rounding via ``round(x, 4)`` and ``{x:.3f}`` formatting
-
-Public API mirrors the bash contract:
-
-  ``compute_cw_por(verdict_file, threshold=None)`` → ``(rc, dict)``
-    rc == 0 on success, ``dict`` is the JSON-ready payload (matches the
-    bash stdout byte-for-byte at the structural level).
-    rc == 2 raises ``FileNotFoundError`` (missing file) or
-    ``ValueError`` (missing/empty ``.voters[]``).
-
-The bash implementation (lib/cw_por.sh) stays in place; this port gives
-Python callers an in-process target and gives the parity gate in
-``tests/unit/test_cw_por_py.py`` a stable surface to compare against the
-live bash subprocess.
-
-Orthogonal to Krippendorff α (Nasser 2026 arxiv:2601.05114): α measures
-agreement reliability but is BLIND to authority-capture. CW-POR (Agarwal &
-Khanna 2025, arxiv:2504.00374 §3.2) is the orthogonal axis — the rate at
-which the panel adopts a high-confidence wrong answer over a low-confidence
-correct one, weighted by the confidence delta. A healthy panel shows low α
-+ low CW-POR or high α + low CW-POR; a captured panel shows high α + high
-CW-POR.

-Idempotent. Fail-open — rc=0 even on partial failures (matches bash
-semantics).
-
-WS4 (bash-removal): conditions are now ``native:<name>`` sentinels that
-``gate_registry`` maps to the in-process evaluators in
-``mini_ork.gates.native_gates`` — the production gate path no longer
-executes the ``gates/*.sh`` shims. Live DBs whose oracle-* rows still
-point at ``<root>/gates/<name>.sh`` keep working: the registry resolves
-those script basenames to the same native evaluators (the script is never
-executed for a recognized oracle gate), so no DB migration is required.
-
-Two-phase insert-then-rename mirrors the bash sequence exactly:
-  (a) INSERT 5 candidate rows with UUID-suffixed gate_ids (matches the bash
-      gate_register output: gate-custom-<hex8>), gate_type='custom',
-      task_class_filter='' initially, safety per the bash roster
-      (coalition/panel-health/synthesis-promote/liveness=1; stability=0),
-      condition=native:<name>
-  (b) UPDATE OR IGNORE the 5 newly-inserted rows to stable oracle-* IDs,
-      DELETE the UUID rows
-  (c) UPDATE task_class_filter=NULL for all oracle-* rows (so gate_list's
-      "task_class_filter IS NULL OR task_class_filter=?" treats NULL as

-Design notes
-------------
-
-* **Lazy CREATE TABLE.** The bash side uses ``_gate_ensure_table``
-  guarded by a per-process ``_MO_GATE_SCHEMA_INIT`` flag. The Python
-  port has no per-process state and is naturally idempotent via
-  ``CREATE TABLE IF NOT EXISTS`` (PRAGMA busy_timeout=5000 to match
-  bash heredoc).
-* **Gate-id parity.** ``gate-<gtype[:6]>-<uuid4().hex[:8]>`` is
-  mirrored exactly so a side-by-side row diff across both
-  implementations matches when the random suffix is excluded.
-* **Native liveness, explicit executable gates.** ``liveness_gate`` uses the
-  native circuit-breaker port. External-callable gate types may execute an
-  explicit executable contract with rc 0=pass, 2=defer, else=fail. Shell
-  function names are intentionally not resolved through an implicit Bash
-  process; unresolved conditions defer.
-* **Native oracle gates (WS4 bash-removal).** Conditions that name one of
-  the 5 oracle gates — either the ``native:<name>`` sentinel seeded by
-  ``gate_bootstrap`` or a legacy ``gates/<name>.sh`` script path from an
-  existing DB row — are evaluated IN-PROCESS via
-  ``mini_ork.gates.native_gates`` (no bash, no subprocess). Unrecognized
-  script paths keep the legacy executable contract.
-* **Bash ``null`` → Python ``None``** for missing/inactive rows.
-
-Public API (mirrors bash function names exactly)::
-
-    from mini_ork.gates.gate_registry import (
-        ensure_table,            # (db_path) -> None
-        gate_register,           # (db_path, gate_type, condition, task_class_filter='', safety=False) -> gate_id
-        gate_evaluate,           # (db_path, gate_id, context_json) -> 'pass'|'fail'|'defer'
-        gate_list,               # (db_path, task_class=None) -> list[dict]
-        gate_run_all,            # (db_path, task_class, context_json, mini_ork_root=None) -> dict
-    )

-Parity is enforced by ``tests/unit/test_gate_registry_py.py`` (>=6
-live-subprocess cases against the bash function).

-"""honest_ci_gate — per-finding confidence intervals from lens votes (Python port).
-
-Faithful strangler-fig port of ``lib/honest_ci_gate.sh``'s
-``mo_compute_finding_cis`` and ``mo_check_ci_widths``. Closes the
-positioning-doc calibration-list item "Honest confidence intervals on
-every claim" (Dai 2025 *Semantic Triangulation*, arxiv:2511.12288).
-
-For each finding it computes:
-
-    n           number of numeric lens votes
-    mean        statistics.fmean of the votes
-    sd          sample stddev (n-1 divisor), statistics.stdev
-    sem         sd / sqrt(n)
-    ci_low/high mean +/- t_{conf, n-1} * sem
-    ci_width    ci_high - ci_low (the "honesty band")
-
-using a small t_critical() table (df<1 -> inf, df<=200 interpolation at
-conf<=0.95 else 1.96; conf > 0.95 -> 2.576).
-
-Public API mirrors the bash contract:
-
-    compute_finding_cis(findings_json, out_path, confidence=None) -> int
-        rc=0 on success, rc=2 on missing arg or unreadable input.
-
-    check_ci_widths(findings_json, report_dir=None, width_ceiling=None,
-                    wide_ratio_ceiling=None) -> tuple[dict, int]
-        Verdict dict shape matches bash's ``print(json.dumps(...))``
-        field-for-field. rc=0 on ``ci_within_band`` or ``indeterminate``;
-        rc=1 on ``CI_TOO_WIDE``.
-
-Env knobs (read only when the corresponding function argument is None):
-
-    MO_CI_CONFIDENCE          default 0.95
-    MO_CI_WIDTH_CEILING       default 2.0
-    MO_CI_WIDE_RATIO_CEILING  default 0.3
-
-The bash script (``lib/honest_ci_gate.sh``) stays in place; this port
-gives Python callers an in-process target and gives
-``tests/unit/test_honest_ci_gate_py.py`` a stable surface to compare
-against the LIVE bash subprocess.
-
-Bash's optional ``mo_grounded_rejection`` integration is NOT replicated
-(out of scope for the port); the verdict JSON shape is preserved so the
-parity test still diff-equals the live bash output.

-"""Krippendorff α calibration gate — Python port of lib/krippendorff_alpha_gate.sh.
-
-Faithful port of ``mo_check_panel_alpha`` from
-``lib/krippendorff_alpha_gate.sh``. Mirrors:
-
-  * missing_run_dir early-return (no score_matrix_path key in JSON)
-  * score-source file loading (default: <run_dir>/panel-verdict.json)
-  * JSON parse-error branch
-  * lens_scores shape validation (must be dict; each value must be list)
-  * per-entry numeric coercion (TypeError/ValueError → indeterminate)
-  * ragged-matrix detection (lens arrays of unequal length)
-  * insufficient_panel branch (lens_count < min_lenses OR item_count==0)
-  * score-matrix TSV write (item_index \\t <lens>...) for audit
-  * Krippendorff α for interval data: α = 1 - D_o/D_e
-    D_o = mean pairwise squared diff per item (column-wise)
-    D_e = mean pairwise squared diff across the flat matrix
-  * constant-marginals fallback → α = 1.0
-  * NaN/Inf guard
-  * low_alpha threshold comparison (rc=1 ALPHA_ESCALATE) else rc=0
-  * verdict-dict shape:
-      {verdict, reason, alpha, alpha_threshold, lens_count, item_count,
-       score_matrix_path, rationale}
-
-Public API mirrors the bash contract:
-
-    check_panel_alpha(run_dir, threshold=None, min_lenses=None,
-                      input_path=None, scores_tsv=None) -> (verdict_dict, rc)
-
-The bash script (lib/krippendorff_alpha_gate.sh) stays in place; this
-port gives Python callers an in-process target and gives
-``tests/unit/test_krippendorff_alpha_gate_py.py`` a stable surface to
-compare against the LIVE bash subprocess.
-
-Why this exists in Python: the bash implementation works by forking a
-``python3 - <<PY`` subprocess every call. The Python port reproduces
-that math in-process so callers that already have a Python runtime
-(pipeline orchestrator, gate-bootstrap, decide()) don't pay fork-exec
-cost on every panel decision.

-"""mutation_adversary — Python port of lib/mutation-adversary.sh.
-
-Faithful port of the *testable* deterministic sub-pipelines of
-``lib/mutation-adversary.sh`` — the cache-hash, the assistant-text JSON
-extraction (jq-stream + brace-balancer + awk-grep fallback cascade), the
-mutations.json shape, and the mutation-validator math (skipped / zero /
-dirty / counted / threshold). The bash function ``mo_run_mutation_validator``'s
-git-apply + npx-playwright loop stays bash-only (it would require a fake
-worktree + Playwright runtime per case = hours of test time). The Python
-port gives callers an in-process surface and gives parity tests a stable
-target to byte-diff against the live bash.
-
-Co-existence model (strangler-fig): bash ``lib/mutation-adversary.sh``
-stays byte-identical. Parity is enforced by
-``tests/unit/test_mutation_adversary_py.py`` (>=6 live-subprocess cases:
-cache-hash via ``printf|shasum`` vs Python; extraction via a bash
-pipeline that wraps the verbatim brace-balancer heredoc vs the Python
-function; validation math via ``jq -n`` vs Python; DB row-shape via
-real ``mo_cache_emit`` vs Python's stdlib ``sqlite3`` INSERT, both
-running against a temp ``db/init.sh``-scaffolded state).

-"""Native evaluators for the 5 oracle gates — replaces the gates/*.sh shims.
-
-WS4 (bash-removal): the production gate path
-(``publisher_node`` → ``gate_bootstrap.bootstrap_oracle_gates`` →
-``gate_registry.gate_run_all`` → ``gate_evaluate``) previously executed the
-registered gate *condition* as a bash script via subprocess. The 5 oracle
-gates seeded by ``gate_bootstrap`` pointed at
-``gates/{coalition,panel-health,synthesis-promote,stability,liveness}.sh`` —
-thin shims that sourced a bash lib, called one function, and mapped the
-JSON verdict onto the rc contract (0=pass, 1=fail, 2=defer).
-
-This module maps each shim onto its staged Python port, preserving the
-shim's exact verdict contract:

-Condition resolution (``resolve_native_evaluator``) recognizes BOTH:
-
-  * the new sentinel conditions seeded by ``gate_bootstrap`` —
-    ``native:<name>`` (e.g. ``native:coalition``), and
-  * the legacy script-path conditions already present in live DBs —
-    any path whose basename is one of the 5 known shim filenames
-    (e.g. ``/repo/gates/coalition.sh``). These rows keep working with
-    zero migration, but no longer execute bash.
-
-Unrecognized conditions fall through to the legacy executable contract in
-``gate_registry._evaluate_external`` (script exists + executable → run it;
-else defer), so user-registered custom script gates are unaffected.
-
-Evaluator signature matches ``gate_registry.GateEvaluator``:
-``(condition, context_json, db_path, mini_ork_root) -> 'pass'|'fail'|'defer'``.

-RNG parity note: bash uses ``awk 'BEGIN{srand(seed)}'`` which is a
-platform-specific linear-congruential generator with 20-digit precision.
-Python's ``random.seed(seed); random.random()`` is Mersenne Twister. The
-two generators produce DIFFERENT sequences for the same seed — the
-parity test asserts equivalence of downstream OUTPUTS (file presence,
-byte-content, label_map keys/families, borda/mean_rank values, sort
-order) NOT raw RNG order. panel_permute_order uses random.seed for its
-own determinism; the parity test asserts Python-vs-Python determinism
-(same seed → identical order, different seeds → different orders) plus
-multiset preservation, NOT byte-equality with bash.

-                                  schema).
-  * ``promotion_approve``      — resolves a ``pending_human_approval`` row
-                                  by UPDATE-then-SELECT and returns a

-                                  conjunction (panel score, CW-POR, ≥1
-                                  structural signal). Soft-dep on CW-POR via

-
-Co-existence model (strangler-fig): ``lib/promotion_gate.sh`` stays
-byte-identical. This port gives Python callers an in-process target and
-gives ``tests/unit/test_promotion_gate_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Public API mirrors the bash contract:
-

-                       require_human=None, mini_ork_root=None) -> dict

-        the candidate has no ``base_workflow_version_id`` row (rc=1 in
-        bash). Floats are rounded to 6 decimals (round(_, 6)).
-
-    promotion_approve(db_path, candidate_id, approver, rationale) -> dict
-        Returns ``{candidate_id, decision, approver, approved_at}``.
-        Raises ``SystemExit`` when no pending row was updated (rc=1 in
-        bash).
-
-    mo_promote_synthesis_gate(verdict_file, task_class, *,

-        classes (default ``code_fix db_migration``) early-return rc=0
-        with reason ``deterministic_class``.
-
-Env knobs (bash reads these at function entry; the Python port reads the
-same env names with the same defaults at function entry — NO import-time
-caching):
-
-    MINI_ORK_REQUIRE_HUMAN_APPROVAL  → promotion_evaluate require_human (default "false")

-"""Python port of ``lib/refute_or_promote_gate.sh``.
-
-Adversarial fabricated-bug injection oracle. Mirrors the bash semantics
-byte-stable so the parity test in
-``tests/unit/test_refute_or_promote_gate_py.py`` can diff live-bash vs
-ported-Python output at dict-equality (json.loads'd) plus 1e-6 float
-tolerance.
-
-Public API:
-    ``generate_fabrications(count, out_path, prefix=None)`` — writes a
-    JSON array of fabrication records; mirrors ``mo_generate_fabrications``.
-    Raises ``ValueError`` on bad args (count<1, non-int, or empty out_path).
-
-    ``check_fabrication_survival(findings_path, fabrications_json,
-    report_dir=None, ceiling=None)`` — returns ``(verdict_dict, rc)``.
-    Mirrors ``mo_check_fabrication_survival``. Same dict shape bash emits
-    on stdout; same rc semantics (rc=0 on validator_grounded or
-    indeterminate; rc=1 on REFUTE_FAILED).
-
-Env knobs honored (overridable via kwargs):
-    ``MO_REFUTE_FP_CEILING``  default 0.1
-    ``MO_REFUTE_PREFIX``      default "__fabricated_"
-    ``MINI_ORK_RUN_DIR``      report_dir fallback (default ".")
-
-Asymmetry (mirror bash):
-    The two shell-level early-return dicts OMIT ``report_path``
-    (findings_path or fabrications_json missing; python3 unavailable).
-    Every other dict shape — including the inner heredoc's missing_inputs
-    branches — INCLUDES ``report_path``.
-
-The bash-only ``mo_grounded_rejection`` side-effect from
-``gates_common.sh`` is intentionally NOT replicated here — Python callers
-wire rejection through their own substrate (per
-``citation_verifier_mechanical.py`` precedent).

-"""rubric_prescreen — Python port of lib/rubric-prescreen.sh (orchestration layer).
-
-Faithful port of the public surface of ``lib/rubric-prescreen.sh``. The
-bash file already lifts three Python heredocs into itself (extracting
-JSON, summarizing artifacts, substituting template markers) — this port
-collapses those back into a Python module while keeping the bash
-control flow (cache lookup → template split → claude subprocess →
-extract → cache emit) mirrored as a callable orchestrator.
-
-Co-existence model (strangler-fig): ``lib/rubric-prescreen.sh`` stays
-byte-identical. Parity is enforced by
-``tests/unit/test_rubric_prescreen_py.py`` (≥6 live-subprocess cases:
-each helper called via real ``bash -c 'source lib/rubric-prescreen.sh
-&& source lib/cache.sh && fn args'`` against a temp
-``db/init.sh``-scaffolded SQLite, then again via the Python port, then
-DB-row + stdout diffed). The orchestrators
-(``mo_run_rubric_prescreen`` / ``mo_rubric_run_score``) shell out to
-non-deterministic subprocesses (claude -p, llm_dispatch); their parity
-is structural (same argv, same DB writes) and not covered by the
-test suite.
-
-SRP split (SOLID refactor): the pure parsing/scoring helpers live in
-``mini_ork/gates/rubric_scoring.py`` and the SQLite cache/DB layer in
-``mini_ork/gates/rubric_cache.py``. This module keeps the orchestration
-+ lane dispatch + ``RubricPrescreenConfig`` and RE-EXPORTS every moved
-public name so existing importers and bash-parity tests are untouched
-(behavior is byte-identical — the bash line-reference comments moved
-with the code).

-Notes on parity:
-- The three Python heredocs lifted from bash are byte-equivalent by
-  construction (they were Python source files wrapped in bash heredocs).
-  The port reproduces them with only the minimum required type hints.
-- ``cache_emit`` uses ``secrets.token_hex(16)`` for the uuid (32 hex
-  chars, no hyphens). The bash version uses ``uuidgen`` which emits a
-  hyphenated UUID. The DB-row diff IGNORES the uuid column (per the
-  plan's risk note) — only logical columns (stage, epic_id, iter,
-  input_hash, status, output_path, log_path, cost_usd, turns,
-  duration_ms, prompt_version) are compared.
-- ``substitute_template`` does FIRST-occurrence-only replacement
-  (mirrors the bash awk splitter at lines 57-66 which splits on the
-  first marker). This is intentionally different from ``str.replace``
-  which would substitute every occurrence. The parity test exercises
-  the first-only semantics.
-- ``cache_costline_from_log`` returns ``(0.0, 0, 0)`` on parse failure
-  (bash emits literal "0 0 0" — three space-separated zeros).
-- ``mo_run_rubric_prescreen`` / ``mo_rubric_run_score`` are not
-  parity-tested: they shell out to ``claude -p`` and ``llm_dispatch``
-  which are non-deterministic. The port mirrors the bash control flow
-  verbatim including argv construction and DB writes.
-- The bash file's own subprocess-on-bash handling
-  (``( set -uo pipefail; ... )``) and the ``|| true`` after the
-  claude call are preserved: the orchestrator never raises on
-  subprocess failure (advisory-only, matches bash semantics).

-Co-existence model (strangler-fig): bash ``lib/scope-overlap.sh`` is

-Notes on parity:
-- ``_rubric_uuid`` in bash calls ``secrets.token_hex(6)`` (12 lowercase
-  hex chars). The port mirrors that verbatim — DO NOT substitute
-  ``uuid.uuid4().hex[:12]``; the formats are equivalent on length but
-  both should still emit lowercased hex, so ``secrets.token_hex(6)`` is
-  the safer one-to-one match.
-- Bash ``rubric_get`` on miss prints literal ``null`` (with a trailing
-  newline from ``print()``). The port mirrors with ``print('null')``.
-- Bash ``verifier_fp_rate`` on zero-results prints literal ``0.0``.
-- Bash ``verifier_fp_rate`` happy-path uses ``f"{fps/total:.4f}"`` —
-  the port mirrors with the same f-string so the emitted text is
-  byte-equal (``"0.2500"`` not ``"0.25"``).
-- The CHECK constraint on ``verifier_results.verdict`` (and the
-  ``NOT (is_false_positive=1 AND is_false_negative=1)`` cross-flag
-  constraint) is enforced at the DB layer. The port does NOT
-  pre-validate; ``sqlite3.IntegrityError`` propagates with rc=1
-  semantics (caller sees the raise — matches bash's ``exit 1``).

-"""GEPA <-> mini-ork adapter.
-
-Integrates the `gepa` framework (github.com/gepa-ai/gepa, `pip install gepa`)
-into mini-ork's existing prompt-optimization scaffolding, upgrading the
-`apo-prompt-tune` "propose a variation" step (kickoffs/auto/arx-6-apo-prompt-
-mutation.md) from a single synthesizer call to GEPA's reflective Pareto evolution.
-
-The text components GEPA optimizes are a recipe's node prompt files
-(`recipes/<recipe>/prompts/{planner,implementer,reviewer}.md`). The score comes
-from REAL downstream outcomes in `execution_traces` (status + verifier +
-tests_passed) plus the `completion_honesty` signal we wired into the reward
-vector. The reflective feedback is built from the failing traces, so GEPA learns
-concrete rules ("on .tsx files run tsc --noEmit before claiming done").
-
-Best-practice notes baked in:
-- Isolation: each candidate is evaluated in a *copied* recipe dir; the real recipe
-  is never mutated during search.
-- Grounded scoring: only real verifier/test outcomes count (no keyword labels).
-- Honesty-aware: a run that claims done but fails is penalized via completion_honesty.
-- Cost-aware: token cost is a soft penalty so GEPA doesn't win by burning money.
-
-Running the search executes REAL mini-ork runs (real spend); do it from the
-mini-ork env. See run_gepa.py for the entry point.
-
-SIBLING MODULE: ``mini_ork.optimize.miniork_adapter`` is the OFFLINE adapter
-(cached execution_traces, no live dispatch) behind the ``GepaAdapter``
-Protocol in ``mini_ork.optimize.gepa``. Use this module (``mini_ork.gepa``)
-for live reflective Pareto evolution with the external gepa framework; use
-``mini_ork.optimize`` for offline/cached optimization loops and tests.

-"""GRPO relative-advantage lane routing — Python port of lib/lane_router.sh (Tier A).
-
-This module persists + reads two ROUTING FACES over the same execution_traces:
-
-  * Legacy face (MO_ROUTER_UCB_C=0, MO_ROUTER_SINGLE_SAMPLE=0):
-      relative_advantage = (lane_mean - group_mean), shrunken, EMA-blended.
-      Within-group shrunken means get stored into agent_performance_memory +
-      lane_domain_advantage + lane_region_advantage exactly as the old code did.
-      ``preferred_lane`` orders by relative_advantage DESC. Single-sample
-      groups (only one lane in the slice) are skipped, same as before.
-
-  * Bandit face (MO_ROUTER_UCB_C > 0):
-      recompute_advantages ALSO computes advantage_var / advantage_std /
-      z_score_advantage per (lane, slice) and writes them into the per-domain
-      + per-region tables. Single-sample groups (when MO_ROUTER_SINGLE_SAMPLE=1)
-      drop their score into lane_slice_baseline as a persistent EMA. The
-      ``preferred_lane`` selector uses the Upper Confidence Bound
-      ``z_score_advantage + C * sqrt(2 ln N / n_lane)`` so under-sampled lanes
-      get explored via the exploit-time ordering. (Follow-up: reroute
-      ``lib/decision_service.sh``'s ε-explore draw to the highest-uncertainty
-      lane too — not yet wired; the ε path is still uniform-random.)
-
-  * NeuralUCB (MO_ROUTER_CONTEXTUAL=1, default OFF):
-      a Linear-Bandit UCB using mini_ork.memory.semantic.HashEmbedder to
-      featurize (task_class, node_type, code_region) and per-lane ridge
-      regression to predict expected reward. Used to break ties between lanes
-      with identical UCB scores. Embedder import + call live strictly inside
-      the gated branch — the default path makes zero extra per-task model
-      calls. (D7)
-
-This is a CONTEXTUAL BANDIT — not canonical GRPO. The advantage estimator
-remains within-group (no importance-sampling / IPS), the UCB bonus is a
-heuristic ordering term not a bound, and NeuralUCB is a linear posterior not
-a deep network. Off-policy correction under near-deterministic logging is
-intentionally NOT attempted (per research note 2509.00648 Fig 3g). The
-comments + docs do not claim zero-cost unbiasedness.
-
-relative_advantage[i] = score[i] - mean(group), score = normalized reward_g
-(NULL rows skipped), grouped by (objective_domain, task_class, node_type,
-code_region). Refinements preserved exactly: per-group shrinkage (K=5), EMA
-blend with prior (α=0.30), recency halflife (14d), cost tie-break on flat
-groups, and the decayed defect-attribution penalty on the region slice.
-Faithful extraction of the bash heredoc; env knobs unchanged.

-"""benchmark_suite — Python port of lib/benchmark_suite.sh.
-
-Faithful port of the four bash entry points: ``benchmark_add``,
-``benchmark_list``, ``benchmark_run``, ``benchmark_results``. The bash
-script is the authoritative source; this module gives Python callers
-an in-process target and gives
-``tests/unit/test_benchmark_suite_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Co-existence model (strangler-fig): ``lib/benchmark_suite.sh`` stays
-byte-identical. This port mirrors the embedded Python heredoc exactly —
-same INSERT column set, same ON CONFLICT update set, same FK bootstrap
-(synthesized epic + run row to satisfy ``benchmark_results.run_id
-REFERENCES runs(id)``), same subprocess wrapper, same summary key
-ordering. Parity is enforced by the sibling test (>=6 live-subprocess
-cases; floats within 1e-6, JSON shapes equal, DB row-diff zero on
-stable columns).
-
-Schema caveat (closed by the test harness): ``lib/benchmark_suite.sh``'s
-private ``_bench_ensure_tables`` builds a STALE DDL (column names
-``id``, ``input``, ``expected_artifact_hash_or_criteria``, INTEGER
-``created_at``) that DIFFERS from migration 0010's column set. The
-bash INSERT itself targets the canonical 0010 columns, so the only
-correct bootstrap path is ``db/init.sh`` (which applies migrations
-0001, 0010, …) — letting bash's private DDL win would crash the
-INSERT with a no-such-column error. The parity test therefore
-bootstraps via ``db/init.sh`` with ``MINI_ORK_HOME`` /
-``MINI_ORK_DB`` env vars, never the bash-side DDL.
-
-DB resolution: bash uses ``${MINI_ORK_DB:?}`` (errors if unset). The
-port raises ValueError when ``db`` is None AND ``MINI_ORK_DB`` is
-unset — it never silently reads a cwd-relative default.
-
-WS5 cutover — runner execution:
-    The bash ``benchmark_run`` shelled out to
-    ``bash -c 'source $MINI_ORK_ROOT/lib/utility_function.sh; <runner_fn>'``
-    with the task JSON on stdin. ``runner_fn`` is now native:
-
-    - a **callable** — invoked in-process with the task dict; it may
-      return a dict (→ JSON-normalised stdout-equivalent), a JSON/plain
-      string (→ stdout-equivalent), or a ``(rc, stdout)`` tuple
-      (→ bash rc + stdout semantics). Exceptions map to the bash
-      subprocess-error path (``err_msg``, ``passed=False``).
-    - the string ``"utility_score"`` — the staged port
-      ``mini_ork.learning.utility_function.score`` computes the score on
-      the task JSON and the stdout contract (``f"{U:.6f}"``, rc 0;
-      rc 1 on invalid JSON) is emulated exactly.
-    - any other string — a legacy shell snippet; unsupported natively
-      (per-task error, ``passed=False``). Migrate to a callable.
-
-    The 300s subprocess timeout is a bash-only concern and is not
-    enforced for in-process runners.
-
-Public surface:
-    add(task_json, db=None) -> str           (returns bench_id)
-    list_(task_class=None, db=None) -> list[dict]
-    run(candidate_id, runner_fn=None, root=None, db=None) -> dict
-    results(candidate_id, db=None) -> list[dict]

-real, trajectory-aware, LLM-judged score. Phase 0 is **advisory**: an ``eval``
-node dispatches a judge over the run's artifact + trajectory; the judge returns
-per-AXIS sub-scores; this module aggregates them **deterministically in code**
-and persists the result onto the existing ``0042`` reward columns with
-``reward_source='eval@v1'``. There is no gate — the run is never blocked or
-slowed by eval, and the judge fails **open** to the rubric/PRM heuristic when it
-is unavailable (the foreign-home "secret missing" failure mode must never sink a
-run).
-
-Why the judge returns axes but *we* aggregate: a single holistic judge score is
-easy for the generator to game (learn to please the judge's gestalt). A fixed
-aggregation over named axes — with safety as a one-way downgrade multiplier — is

-"""Failure-class state machine for durable-DAG recovery (E3).
-
-Design source: ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md`` §5.
-
-Every stopped node attempt is classified into exactly one of five classes.
-The class decides recovery policy — crucially, whether the whole run is marked
-failed and whether an automatic (unattended) recovery is allowed:
-
-    class            leaves recovery record?   auto-recover?   marks run failed?
-    ---------------  ------------------------   -------------   -----------------
-    infra_interrupt  yes                        YES (re-run)    no
-    provider_limit   yes                        no (explicit)   no
-    output_invalid   yes                        no (repair)     no
-    input_required   yes                        no (human)      no
-    terminal         no                         no              YES
-
-The load-bearing invariants (design §5, kickoff acceptance):
-
-  * A ``max-turns`` stop is ``provider_limit`` — NOT ``infra_interrupt`` — so
-    it never triggers an unbounded auto-retry loop. Any new LLM attempt for a
-    ``provider_limit``/``output_invalid`` stop is explicit and budget-bounded
-    (see ``lease.can_dispatch``).
-  * ONLY ``terminal`` marks the run failed. The other four leave a durable
-    recovery record so an operator (or the auto-policy, for infra) can resume.
-  * Unknown/unrecognized stops default to ``terminal`` — fail-closed. The
-    node's E1 checkpoints still persist, so a terminal run remains *manually*
-    recoverable via the E2 planner; it simply won't auto-recover or burn spend
-    on a stop we could not classify.
-
-This module is pure (no I/O) so it is trivially testable and callable from
-both the checkpoint writer and the recovery planner.

-_GRADIENT_EXTRACTOR_PROMPT_TEMPLATE = """You are a recipe-design improvement analyst.
-
-Given the execution trace below, extract 0 to 5 textual gradients — specific,
-actionable improvement signals. The trace may describe an algorithmic
-workflow (planner → implementer → verifier) OR a coordination workflow
-(4 lenses → synthesizer → publisher). Find what about THIS RECIPE design
-would have made the outcome better.
-
-Five target families (pick the most specific that fits each gradient):
-
-  1. "workflow.node.<name>"           — algorithmic improvement to one node
-                                        (e.g. planner missed a step, verifier
-                                        accepted a bad artifact)
-  2. "agent.<role>.prompt"            — prompt-level improvement (e.g. the
-                                        lens prompt produced shallow output;
-                                        the synthesizer prompt missed an axis)
-  3. "workflow.edge.<name>"           — dependency / sequencing refinement
-                                        (e.g. depends_on should be
-                                        supplies_context_to; this edge needs
-                                        a retries policy)
-  4. "verifier.<name>"                — verifier-script logic gap
-                                        (e.g. the grep-assert missed a
-                                        boundary condition)
-  5. "workflow.recipe.<recipe_name>"  — RECIPE-LEVEL shape suggestion when
-                                        the issue is the dispatch topology
-                                        itself, not any single node (e.g.
-                                        the 4-lens panel has 2 lenses in the
-                                        same family; the synthesizer should
-                                        be a different family from any lens;
-                                        a missing publisher node lets
-                                        artifacts vanish from the audit)
-
-TRACE:
-<<<TRACE_JSON>>>
-
-Important: if the trace is from a coordination-shaped recipe (audit,
-synthesis, multi-lens debate), prefer "workflow.recipe.<name>" or
-"agent.<role>.prompt" gradients — those are where the leverage actually
-lives. Do NOT respond with [] just because no algorithmic bug stands out;
-coordination shapes ALWAYS have a recipe-design improvement to surface
-(family-diversity, verifier contract, synthesis aggregation, etc).
-
-Respond ONLY with a JSON array of gradient objects. Each object must have:
-  "target"          : string — one of the 5 target families above
-  "signal"          : string — what was observed (1-2 sentences)
-  "suggested_change": string — concrete recommendation (1-2 sentences)
-  "confidence"      : number — 0.0 to 1.0
-
-If after honest analysis you genuinely find nothing to improve (rare —
-audit yourself before defaulting), respond with []. No prose, no markdown
-fences, only the JSON array."""

-"""Layer 2 of the truth-grounded eval stack — metamorphic / gold-free testing.
-
-Where Layer 0 asks "did the given tests pass?", Layer 2 asks "does the patched
-code hold invariances the given tests never checked?" — catching the failure a
-single extensional test misses: a patch that passes the exact test inputs but is
-wrong on nearby inputs (overfitting to the test / coverage-gap gaming). No
-ground-truth label is needed: a metamorphic relation is a property that must
-hold *between* related executions of the same program.
-
-The verdict is ALWAYS execution-grounded. A relation is violated iff running it
-produces a concrete counterexample, so an LLM that merely *proposes* relations
-can never corrupt the verdict — a bad proposal simply fails to reproduce a real
-violation. This is what keeps Layer 2 truth-grounded while escaping the
-"no oracle" wall.
-
-Grounding: arXiv 2603.24774 (LLM proposes metamorphic relations, execution is
-the oracle), arXiv 2510.26423 (execution-grounded oracle synthesis); and this
-repo's own finding that a single extensional test is hackable through coverage
-gaps while metamorphic relations over amplified inputs are not.
-
-Pure engine — no IO, no dispatch. Callers (a recipe verifier, an offline grader,
-or an LLM-proposer wrapper) supply the function under test, seed inputs, and
-relations; this module runs them and reports an execution-grounded verdict whose
-``to_verifier_json()`` drops straight into Layer 0's execution reward (it is read
-as one more ``verifier_*.json`` pass signal).

-Faithful port of ``lib/process_reward.sh::prm_score_trace``. Approximates a

-function remains the canonical scorer (this module co-exists via the
-strangler-fig pattern) and parity is enforced by
-``tests/unit/test_process_reward_parity.py`` which invokes the live bash
-function and compares scores within ``1e-6``.

-================  ======  ==================================================

-success-only bonus (combined activity clamped at ``ACTIVITY_CAP=0.15``). A bare

-This sharpens the success/failure separation the GRPO group-relative advantage

-disables the activity clamp for A/B comparison.
-
-Same-family decontamination is INTENTIONALLY ABSENT: the doer's lane is

-"""Reflection-refiner sub-pipelines — Python port of lib/reflection-refiner.sh.
-
-Faithful port of the *deterministic* sub-pipelines of `mo_run_reflection_refiner`
-and `mo_append_reflection_to_feedback`. The LLM call (claude -p with budget/cache
-flags) stays in bash — it requires live model + provider env scripts and is
-out of scope for pytest. The Python port gives callers an in-process surface
-and gives parity tests a stable target to byte-diff against the live bash.
-
-Co-existence model (strangler-fig): bash `lib/reflection-refiner.sh` is the
-authoritative source. This module mirrors its sub-pipelines exactly. Parity
-is enforced by `tests/unit/test_reflection_refiner_py.py` (>=6 cases that
-invoke `jq`/`awk`/`sed`/`sqlite3` via subprocess and diff against the Python
-output byte-for-byte; floats 1e-6).
-
-Pipeline map (bash function → Python):
-  mo_run_reflection_refiner:
-    early-bail (missing bdd-verdict / verdict!=FAIL)      → should_run
-    sqlite query 'SELECT kickoff_path FROM epics WHERE id=:epic' → read_kickoff_path
-    jq failure-summary projection                          → format_failure_summary
-    awk+awk+awk split / sed {{KICKOFF_PATH}} replace / cat → build_prompt
-    awk '^## Reflection refiner/,/EOF/' extraction        → extract_reflection

-"""Pure-logic port of ``lib/rho_aggregator.sh``.
-
-Faithful port of the two pure/deterministic callables of the bash
-Retrospective Harness Optimization (RHO) aggregator (arXiv:2606.05922).
-The bash file resolves ``STATE_DB`` at *source* time from
-``${MINI_ORK_DB:-${MINI_ORK_HOME:-.mini-ork}/state.db}``; the Python
-port takes the database path as a parameter instead, which is the
-controllable equivalent.
-
-Bash function inventory (verbatim from ``lib/rho_aggregator.sh``)::
-
-    rho_aggregate_win_rates [--since EPOCH] [--task-class X]
-        Re-aggregate from ``execution_traces``. Idempotent: upserts the
-        row keyed by ``(prompt_version_hash, task_class)`` into
-        ``prompt_win_rates``. Emits the row count on stdout.
-
-    rho_top_prompts <task_class> <node_type> [<top_n>]
-        Print the top-N prompts by ``win_rate`` for the given
-        ``task_class`` + ``node_type`` filter, ``sample_size >= 3`` to
-        avoid one-shot noise.
-
-Parity-mapping contract (must remain exact)::
-
-    bash                                     python
-    -------------------------------------------------------------------------------
-    rho_aggregate_win_rates [..]   ─►  aggregate_win_rates(state_db, since=0,
-                                                            task_class="")
-                                       returns int (row count printed by bash)
-    rho_top_prompts tc nt [n]      ─►  top_prompts(state_db, task_class, node_type="",
-                                                    top_n=5)
-                                       returns str (the full multi-line stdout,
-                                       trailing newline preserved)
-
-Output-format parity notes (verified against live bash on a 3-trace seed)::
-
-    * ``win_rate`` is rounded to 4 dp on insert (``round(wr, 4)``) and
-      printed at 3 dp by ``top_prompts`` via ``printf '%.3f'``. Python
-      mirrors with ``round(x, 4)`` / ``f"{x:.3f}"``.
-    * ``sample_size`` printed as ``printf '%4d'`` (width 4, right-aligned).
-    * Hash printed as ``printf '%-12s'`` over the first 12 chars (left-aligned).
-    * ``node_type`` printed via ``COALESCE(node_type,'?')`` — so a NULL
-      node_type always renders as ``?``.
-    * Filter clause ``(node_type IS NULL OR node_type = X)`` means a
-      NULL node_type row passes any node_type filter; this is preserved.
-
-Float equality is enforced at ``<1e-6`` for ``win_rate``-shaped outputs;
-string equality is exact after ``.strip()`` for the formatted table.
-
-``tests/unit/test_rho_aggregator_parity.py`` enforces this parity over a
-fixture corpus of ``>=6`` cases by shelling out to live bash via
-``subprocess.run`` and comparing byte-for-byte.

-"""Pure-logic port of ``lib/utility_function.sh::utility_score``.
-
-Faithful port of the **default formula branch** of the bash utility-score
-function (Ch 18). The bash source is a thin shell that resolves a per-task
-override and otherwise delegates to an embedded Python heredoc; this module
-lifts that heredoc into a normal importable function and exposes the
-deterministic helpers it depends on.
-
-The per-task override path (``${MINI_ORK_HOME}/config/utility_functions/
-<task_class>.sh``) is impure I/O and is intentionally **not** ported here.
-Parity fixtures omit ``task_class`` so both bash and Python fall through to
-the default formula; callers needing the override path should call the bash
-function directly.
-
-Public API::
-
-    from mini_ork.learning.utility_function import score
-
-    score(run_result_json, weights=None) -> float
-
-``weights`` is a dict with any of ``success``, ``verifier``, ``quality``,
-``cost``, ``latency``, ``risk``. Missing entries fall back to the
-``MINI_ORK_W_*`` environment defaults (matching ``lib/utility_function.sh``'s
-``_UTILITY_W_*`` constants).
-
-Default formula (mirrors bash verbatim)::
-
-    U = w_success*success + w_verifier*verifier_score + w_quality*quality_score
-        - w_cost*norm_cost - w_latency*norm_latency - w_risk*risk_penalty
-
-All components are clamped to ``[0.0, 1.0]`` before combination and ``U`` is
-clamped to ``[0.0, 1.0]`` before return. Score rendering matches bash's
-``f"{U:.6f}"`` format.
-
-``tests/unit/test_utility_function_parity.py`` enforces float parity (within
-``1e-6``) between this module and the live bash subprocess over a fixture
-corpus of ``>=6`` cases.

-"""Python port of ``bin/mini-ork-bug-collector`` — auto-dispatched side-issue scanner.
-
-Strangler-fig parity port of the bash dispatcher. The bash
-``bin/mini-ork-bug-collector`` stays in place (strangler-fig KEEP
-invariant per the migration kickoff); this module gives Python
-callers an in-process surface and gives the parity test a stable
-target to byte-diff against the live bash subprocess.
-
-Source-of-truth: ``bin/mini-ork-bug-collector`` lines 2-32 (extracted
-by bash ``--help`` via ``sed -n '2,32p'`` then stripping a leading
-hash-space or bare-hash from each line).
-The literal ``_USAGE_BLOCK`` below is hand-mirrored; ``test_help_parity``
-re-verifies it on every CI run so any drift in the bash docblock is
-caught immediately.
-
-Pipeline map (bash branch → Python dispatch):
-  --mode off                          → return 0 (bash line 50)
-  --mode heuristic  [--output-file X] → _resolve_scan_targets → heuristic_scan
-  --mode llm                          → stderr stub + return 0 (lines 162-164)
-  unknown mode                        → stderr msg + return 0 (lines 167-170)
-  --help / -h                         → print _USAGE_BLOCK to stdout, return 0
-
-Env resolution (mirrors bash lines 27-32):
-  * ``MINI_ORK_ROOT``        — repo root; default = parent of ``mini_ork`` package
-                                (mirrors ``readlink -f`` canonicalization).
-  * ``MINI_ORK_HOME``        — runs root; default ``$MINI_ORK_ROOT/.mini-ork``.
-  * ``MINI_ORK_RUN_DIR``     — per-run sink dir; default ``/tmp``.
-  * ``MO_BUG_COLLECTOR_MODE`` — default mode (bash line 34).
-
-Output semantics:
-  * Heuristic path: appends one JSONL row per finding to
-    ``${MINI_ORK_RUN_DIR}/noticed_bugs.jsonl`` (separators=(",", ":"),
-    utf-8, trailing ``\\n``). Mirrors bash heredoc exactly.
-  * Always writes ``f"{emitted}\\n"`` to stderr on the heuristic
-    path (mirrors bash ``print(emitted, file=sys.stderr)``).
-  * ``--mode llm`` writes ``"  [bug-collector] llm mode not yet
-    implemented; use --mode heuristic\\n"`` to stderr (mirrors bash
-    echo >&2 at line 163).
-  * Unknown mode writes ``f"bug-collector: unknown mode '<mode>'\\n"``
-    to stderr (mirrors bash line 168).
-  * Returns 0 in every branch — bash always exits 0 (line 173).
-
-Parity is enforced by ``tests/unit/test_mini_ork_bug_collector_py.py``
-(8 cases that drive the LIVE bash subprocess against a sandbox run-dir
-and diff the resulting ``noticed_bugs.jsonl`` + stderr + exit-code
-against the Python port byte-for-byte; floats 1e-6 on confidence).

-"""Bug-report channel + orchestrator queue — Python port of ``lib/bug_report.sh``.
-
-Faithful port of the six bash public functions that implement the per-agent
-noticed-but-deferred bug reporting channel and the orchestrator queue that
-dedupes, ranks, and promotes top-N into new epics. The bash
-``lib/bug_report.sh`` stays in place (strangler-fig co-existence); this
-module gives Python callers an in-process surface and gives the parity test
-a stable target to byte-diff against the live bash subprocess.
-
-Pipeline map (bash function → Python):
-  bug_report_emit       → bug_report_emit       (validate → append JSONL row)
-  bug_report_sweep      → bug_report_sweep      (walk .mini-ork/runs → upsert bug_reports)
-  bug_report_prioritize → bug_report_prioritize (ranked open rows, bash printf format)
-  bug_report_promote    → bug_report_promote    (top-N → epic rows + kickoff files)
-  bug_report_list       → bug_report_list       (recent rows, bash printf format)
-  bug_report_show       → bug_report_show       (sqlite3 -line format)
-
-Internal helpers (mirrors of bash underscore-prefixed functions):
-  _bug_report_now         → _now                  (int epoch seconds)
-  _bug_report_severity_weight → _severity_weight (critical=8 high=4 medium=2 low=1)
-  _bug_report_fingerprint → _fingerprint          (sha256 of normalized title)
-
-Env knobs honored (also accepted as explicit kwargs):
-  * ``MINI_ORK_DB``         — state.db path (default ``${MINI_ORK_HOME:-.mini-ork}/state.db``).
-  * ``MINI_ORK_HOME``       — runs root (``.mini-ork`` by default) for sweep.
-  * ``MINI_ORK_RUN_DIR``    — per-run sink dir (``/tmp`` by default) for emit.
-  * ``MINI_ORK_ROOT``       — repo root for promote kickoff files
-    (default: parent of ``mini_ork/`` package, mirrors bash's
-    ``cd "$(dirname "${BASH_SOURCE[0]}")/.."``).
-
-Output format mirrors:
-  * ``bug_report_prioritize`` / ``bug_report_list`` emit rows joined by
-    ``" | "`` with a trailing ``"\\n"`` (mirrors ``sqlite3 -separator ' | '``).
-  * ``bug_report_show`` emits key/value lines (``key = value\\n``) terminated
-    by a blank ``\\n`` (mirrors ``sqlite3 -line``).
-
-Parity is enforced by ``tests/unit/test_bug_report_py.py`` (>=6 cases that
-drive the LIVE bash subprocess against a temp DB seeded by ``db/init.sh``
-and diff the resulting ``bug_reports`` rows + JSONL sinks + stdout strings
-against the Python port byte-for-byte; floats 1e-6 on confidence;
-epochs 1-second tolerance).

-"""mo_emit_hook — Python port of lib/mo_emit_hook.sh.
-
-Faithful port of the internal bash helper ``_mo_emit_hook``: an outbound
-event-callback hook that turns mini-ork's DB-only event emission into a
-push channel for external observers (dashboards, CI bridges, chat bots).
-The hook is a single shell command supplied via the ``MINI_ORK_ON_EVENT``
-env var. Mini-ork calls it best-effort after every DB write with three
-positional args (event_type, run_id, payload_json); non-zero exit,
-timeout, or missing command is logged-and-swallowed so observability
-never breaks dispatch.
-
-Co-existence model (strangler-fig): ``lib/mo_emit_hook.sh`` stays
-byte-identical. This port gives Python callers an in-process target and
-``tests/unit/test_mo_emit_hook_py.py`` a stable surface to diff against
-the LIVE bash subprocess.
-
-Behavioural parity (every branch from the bash original is preserved):
-
-  1. ``MINI_ORK_ON_EVENT`` unset or empty → silent no-op (return 0).
-  2. Missing positional args default to ``"unknown"`` / ``""`` / ``"{}"``
-     to match bash's `${1:-unknown}` / `${2:-}` / `${3:-...}` default
-     expressions. The literal payload default is the two-byte string
-     ``{}`` — NOT ``json.dumps({})`` (same bytes, different meaning).
-  3. Relative ``.sh`` path is resolved to absolute via the bash regex
-     anchored at first-char-not-slash, ending in literal ``.sh``. If the
-     file exists, it is rewritten as ``$(cd dirname && pwd)/basename``;
-     non-relative paths and non-``.sh`` paths pass through unchanged.
-  4. Timeout binary is probed in bash's priority order:
-     ``gtimeout`` (GNU coreutils on macOS) preferred, ``timeout`` as
-     fallback. If neither is on PATH, the hook runs unguarded — matches
-     bash's two-branch ``if [ -n "$timeout_bin" ]`` decision.
-  5. Hook invocation is hard-capped at 5 seconds; stdout and stderr are
-     redirected to ``DEVNULL``; non-zero exit codes are swallowed
-     (``|| true`` in bash; bare ``subprocess.run`` in Python — it
-     already raises only on timeout, which the caller catches).
-  6. ``shell=False`` so the user's chosen binary wins, matching bash's
-     direct ``exec`` (no PATH re-interpretation, no shell-quoting bugs).
-
-Public surface:
-    mo_emit_hook(event_type: str = "unknown",
-                 run_id: str = "",
-                 payload_json: str = "{}") -> None
-
-Returns None; never raises on hook failure (best-effort observability).
-The sole documented failure mode of the *bash* version is that a missing
-``MINI_ORK_ON_EVENT`` is a no-op — this port preserves that contract.

-"""Node-events emit — Python port of lib/mo_node_events.sh.
-
-Faithful port of the run_events emission helpers used by mini-ork to power
-the per-node DAG status view in the observability UI. The Python port gives
-callers an in-process surface (no `python3` heredoc per call) and gives the
-parity test a stable target to byte-diff against the live bash.
-
-Co-existence model (strangler-fig): bash `lib/mo_node_events.sh` is the
-authoritative source. This module mirrors its surfaces exactly. Parity is
-enforced by `tests/unit/test_mo_node_events_py.py` (>=6 cases that drive
-the LIVE bash subprocess against a temp DB seeded by `db/init.sh` and diff
-the resulting `run_events` rows against the Python port byte-for-byte;
-floats 1e-6 on integer epoch columns).
-
-Schema citations:
-  - `run_events` base table  — db/migrations/0016_recursive_orchestration.sql
-      (event_id, run_id, parent_run_id, event_type, payload_json, created_at)
-  - `run_events.finish_reason`  — db/migrations/0021_error_taxonomy_finish_reasons.sql
-  - `run_events.last_heartbeat_at`  — db/migrations/0023_node_heartbeat_fuse.sql
-
-Pipeline map (bash function → Python):
-  _mo_now_ms              → _now_ms          (gdate → time.time_ns → seconds*1000)
-  mo_node_emit            → mo_node_emit     (required-arg guards + schema-aware insert)
-  mo_node_start           → mo_node_start    (model_lane convenience)
-  mo_node_end             → mo_node_end      (build_extra_json + delegate)
-  mo_emit_node_heartbeat  → mo_emit_node_heartbeat
-  mo_node_emit_end_trap   → mo_node_emit_end_trap
-        (signature drift: bash uses RETURN-trap + caller-scope vars; the port
-        takes them as explicit args. Bash callers cannot 1:1 swap.)
-
-Signature deltas vs bash (documented for callers):
-  - `mo_node_emit_end_trap`: bash reads `_mo_run_id`, `_mo_node_start_ms`,
-    `node_id`, `node_type`, `VERDICT`, `CONTEXT_FILE`, `IMPL_LOG`, `REVIEW_FILE`,
-    `MO_NODE_FINISH_REASON` from the caller's scope (RETURN-trap pattern).
-    Python has no caller scope, so the port takes them as explicit args. Bash
-    also auto-resolves artifact via `CONTEXT_FILE → IMPL_LOG → REVIEW_FILE`
-    chain; the port takes a single resolved `context_path` and the caller
-    must perform the chain.
-  - `_now_ms` is the public name of bash's `_mo_now_ms` (the leading
-    underscore is dropped to match Python idioms; the bash function name
-    is preserved in the docstring for grep parity).

-"""Span-buffer for live OTel — Python port of lib/mo_otel.sh.
-
-Faithful port of the JSONL span emitter used by mini-ork to flush a
-run's lifecycle events to Langfuse via the OTLP/JSON exporter. The Python
-port gives callers an in-process surface (no `bash`/subprocess per call)
-and gives the parity test a stable target to byte-diff against the live
-bash.
-
-Co-existence model (strangler-fig): bash `lib/mo_otel.sh` is the
-authoritative source. This module mirrors its surfaces exactly. Parity is
-enforced by `tests/unit/test_mo_otel_py.py` (>=6 cases that drive the
-LIVE bash subprocess against a per-case MINI_ORK_RUN_DIR temp dir and
-diff the resulting `.otel-spans.jsonl` buffer line-by-line against the
-Python port byte-for-byte; the `flush` case uses MO_OTEL_DRY_RUN=1
-against a `db/init.sh`-seeded state.db and diffs the printed OTLP
-payload). Internally-generated timestamps (`root_begin.start_ms`,
-`root_end.end_ms`) are compared within a 1500ms tolerance window
-(subprocess-drift between the bash and Python invocations is expected);
-explicit-arg timestamps (`mo_otel_agent`'s `start_ms`/`end_ms`) are
-compared exactly.
-
-Gating mirrors lib/mo_otel.sh:11-19:
-  MO_OTEL=1                  master switch — without it every function
-                              no-ops and returns 0
-  MINI_ORK_RUN_DIR           buffer location (.otel-spans.jsonl lives here);
-                              mo_otel_enabled() requires it set
-  MO_OTEL_DRY_RUN=1          flush prints the OTLP payload instead of POSTing
-  LANGFUSE_PUBLIC_KEY/SECRET flush leaves the host; without creds the JSONL
-                              buffer survives on disk for a later resync
-
-Failure mode: best-effort everywhere (mirrors bash). Observability must
-never break execution — every entry point returns 0.
-
-Pipeline map (bash function → Python):
-  mo_otel_enabled     → mo_otel_enabled     (MO_OTEL=='1' AND MINI_ORK_RUN_DIR set)
-  mo_otel_buf         → mo_otel_buf         (run_dir/.otel-spans.jsonl, '/.' fallback)
-  _mo_otel_now_ms     → _now_ms             (gdate → time.time_ns → seconds*1000)
-  mo_otel_emit        → mo_otel_emit        (append + newline; swallow OSError)
-  mo_otel_root_begin  → mo_otel_root_begin  (delegates to mo_otel_emit)
-  mo_otel_root_end    → mo_otel_root_end    (rc=='0' → 'success', else 'failure')
-  mo_otel_agent       → mo_otel_agent       (delegates to mo_otel_emit)
-  mo_otel_flush       → mo_otel_flush       (subprocess python3 -m mini_ork.otel_export)
-
-JSON key/whitespace parity: the bash printf strings at lib/mo_otel.sh:54,
-63, 71 emit no-space JSON (`{"type":"agent","node_id":"...",...}`). The
-port reproduces that shape via `json.dumps(payload, separators=(",", ":"))`
-with dict keys inserted in the same order as the bash printf — both the
-buffer-diff and the flush-payload diff rely on this for byte-equality
-(structural compare tolerates drift, but we don't want to depend on it).

-"""Pure-logic + DB-access port of ``lib/topology_metrics.sh``.
-
-Faithful port of the deterministic panel-topology measurement logic in
-``lib/topology_metrics.sh``. The bash function (a wrapper around several
-inline ``python3 - <<'PY'`` heredocs) reads from ``execution_traces``,
-computes three axes of realised panel topology — ρ (output correlation),
-C (context formation distance), I (inductive prior distance) — and
-classifies them into one of eight quadrants from the framework doc:
-
-    docs/_meta/research/20260602-2030-context-formation-diversity-framework-multi-agent-panels.md
-
-This module lifts the heredoc bodies into proper Python functions and
-provides both:
-
-  * **Pure helpers** (no I/O):  family_of, classify_quadrant, _quadrant_thresholds,
-                                 _compute_rho, _compute_C, _compute_I
-  * **DB wrappers** (sqlite3):  ensure_table, measure_rho, measure_C,
-                                 measure_I, measure_topology
-
-The bash function ``measure_topology`` is the canonical post-cycle hook.
-This module mirrors it 1:1 and writes the row to
-``panel_topology_telemetry`` using the SAME column list and the SAME
-``pt-<panel_run_id[:16]>-<uuid6>`` ``telemetry_id`` format.
-
-Public API (mirrors bash function names exactly)::
-
-    from mini_ork.observability.topology_metrics import (
-        ensure_table,                  # (db_path) -> None
-        family_of,                     # (version_id, lane_to_family=None) -> str
-        measure_rho,                   # (db_path, panel_run_id) -> float
-        measure_C,                     # (db_path, panel_run_id) -> float
-        measure_I,                     # (db_path, panel_run_id, root) -> float

-        measure_topology,              # (db_path, panel_run_id, recipe, root) -> telemetry_id
-    )
-
-Co-existence model (strangler-fig): ``lib/topology_metrics.sh`` stays
-byte-identical. The Python port mirrors its public API semantically.

-"""Python port of bin/mini-ork-usage-report — per-(code_region, lane) report.
-
-Strangler-fig co-tenant: ``bin/mini-ork-usage-report`` stays untouched; this
-port gives Python callers an in-process target and the parity test a stable
-surface for byte-for-byte comparison against the live bash. The bash script
-composes two embedded Python heredocs (collect + render); this port splits
-those into pure functions so tests can pin inputs/outputs and the smoke
-self-test can run in-process without a nested subprocess round-trip.
-
-Public surface (mirrors bash sub-commands + smoke self-test):
-
-    collect_region_expertise(db_path, since=0) -> dict
-    render_json(report) -> str                   # indent=2 + sort_keys=True + '\\n'
-    build_smoke_db(db_path) -> None              # CREATE TABLE + seed rows
-    run_smoke() -> int                           # build tmp dir, run + assert
-    parse_argv(argv) -> tuple                    # mirrors bash case block
-    help_text() -> str                           # bash heredoc verbatim
-    main(argv=None, *, stdout=None, stderr=None) -> int
-
-Output parity:
-
-* The bash script emits JSON via ``json.dump(report, f, indent=2,
-  sort_keys=True)`` + a single trailing ``\\n``. Python must mirror
-  exactly. ``sort_keys=True`` is load-bearing: the multi-region/lane
-  case depends on lexicographic entry ordering for byte-equality.
-* Datetime format string is ``%Y-%m-%dT%H:%M:%fZ`` (Python 6-digit
-  microseconds). The defect_attributions timestamp parser accepts
-  both ``%Y-%m-%dT%H:%M:%fZ`` (Python-style) and ``%Y-%m-%dT%H:%M:%SZ``
-  (SQLite-style, 3-digit milliseconds or no-fraction) — both forms
-  appear in legacy migration seeds.
-* Missing-DB branch emits ``{"generated_at", "source_db", "since",
-  "entry_count": 0, "entries": [], "note": "state.db not found; no
-  region evidence to summarize"}``. The ``note`` field is ONLY present
-  in this branch — production + smoke paths omit it.
-
-Env knobs honored (also accepted as explicit kwargs to ``main()``):
-
-* ``MINI_ORK_DB``   — state.db path (default
-  ``${MINI_ORK_DB:-${MINI_ORK_HOME:-$(pwd)/.mini-ork}/state.db}``).
-* ``MINI_ORK_HOME`` — base dir for the default DB path.
-
-Parity is enforced by ``tests/unit/test_mini_ork_usage_report_py.py``
-(8 cases driving the LIVE bash subprocess against a temp DB seeded by
-``db/init.sh`` and comparing parsed region_expertise.json dicts with
-floats within 1e-6, ``generated_at`` ignored).

-"""active_state_index.py — Python port of lib/active_state_index.sh.
-
-Faithful strangler-fig port (HarnessBridge Technique 1, arxiv:2606.12882).
-The bash function ``mo_active_state_block`` in ``lib/active_state_index.sh``
-stays in place; this module gives Python callers an in-process target and
-gives tests a stable surface for parity verification against the live
-bash subprocess.
-
-Public API:
-    render_active_state_block(task_class='__any__', days_window=30,
-                              max_per_section=None, db_path=None,
-                              disabled=None) -> str
-
-Behavior mirrors the bash function byte-for-byte:
-    - MO_DISABLE_ACTIVE_STATE=1 (env) or disabled=True → return ""
-    - Internal helpers (_unresolved_errors, _open_constraints,
-      _established_facts, _pending_goals) guard on table presence and
-      return [] when the relevant sqlite_master row is missing.
-    - DECISION_VARIABLES is the static 6-entry list; the empty-block
-      shortcut (total==0 AND len(d)==0) is preserved verbatim even
-      though it's unreachable with the static list.
-    - Final assembly prints the markdown wrapper ('--- ACTIVE STATE
-      INDEX ... ---' fences + ```json ...``` + optional
-      '**Summary:** N ...' line) byte-equal to bash output.
-
-Env knobs (read at call time, matching bash's lookup order):
-    MINI_ORK_DB                    — db path (overridable via db_path kwarg)
-    MO_DISABLE_ACTIVE_STATE=1      — short-circuit to empty string
-    MO_ACTIVE_STATE_MAX_PER_SECTION — cap per section (default 5)

-"""mini_ork_coord — Python port of bin/mini-ork-coord CLI dispatcher.
-
-Faithful Python port of the thin bash wrapper at ``bin/mini-ork-coord``.
-The bash wrapper sources ``lib/coord_registry.sh`` and ``lib/coord_gate.sh``
-then dispatches ``argv[1]`` to one of the public coord_* / coord_gate_*
-functions. This module does the same by dispatching to the already-ported
-peer modules ``mini_ork.registries.coord_registry`` and
-``mini_ork.gates.coord_gate``.
-
-Strangler-fig: ``bin/mini-ork-coord`` stays byte-identical at git HEAD;
-this port is additive and gives Python callers an in-process target while
-``tests/unit/test_mini_ork_coord_py.py`` enforces byte-level parity.
-
-Subcommand contract:
-    acquire <agent> <path> <mode> [ttl_seconds]  → lease id on stdout (rc=0/4)
-    release <lease_id>                            → exit 0 on success
-    renew   <agent> <lease_id> [ttl_seconds]     → exit 0 on success (holder only)
-    gate    <agent> <path> <mode>                 → rc=0 (advisory) / rc=11 (strict deny)
-    metrics                                       → prints metrics JSON to stdout
-    audit    [N]                                  → prints last N audit records
-
-Exit codes (mirrors bash exactly):
-    acquire  0 / 1 (conflict) / 2 (usage) / 4 (deadlock)
-    release  0 / 1 / 2
-    renew    0 / 1 / 2 / 3 (not holder)
-    gate     0 / 2 (usage) / 11 (strict deny)
-    metrics  0
-    audit    0
-    help     0
-    unknown  2
-
-argv parsing parity: bash uses ``${1:-}`` (empty-default) for missing
-positional args; this module routes missing positional args through empty
-strings so the rc=2 'usage' stderr path stays identical.

-"""Python port of lib/harness_wrapper.sh.
-
-Wraps a full coding-agent harness (claude-code, codex-cli, gemini-cli) as a
-workflow node. Reads the bash source of record (lib/harness_wrapper.sh) and
-re-implements its dispatch contract in Python so test code and future Python
-callers can invoke it as an in-process callable. The bash file remains the
-system of record — DO NOT edit lib/harness_wrapper.sh; the parity test in
-tests/unit/test_harness_wrapper_py.py fails if the bash source drifts from
-what the port expects.

-"""mini-ork lifetime — operator CLI for the lifetime leaderboard (Python port).
-
-Faithful port of ``bin/mini-ork-lifetime`` (3 subcommands: ``show``,
-``conductor-history``, ``summary``). All three are read-only sqlite3
-queries against ``state.db`` and produce stdout that must match the live
-bash control byte-for-byte (floats within 1e-6, ints exact, dates
-honor ``TZ``). The bash script stays in place (strangler-fig
-co-existence); this module gives Python callers an in-process surface
-and the parity test a stable target.
-
-Public surface (mirrors bash functions):
-
-    show(recipe, task_class=None)         → show <recipe> [--task-class X]
-    conductor_history(n=10)               → conductor-history [N]
-    summary()                             → summary
-    help_text()                           → bash `cat <<EOF` block
-    main(argv=None)                       → CLI dispatcher (exit codes mirror bash)
-
-Output format mirrors:
-
-* ``sqlite3 -separator ' | '`` mode: rows joined by ``" | "`` with each
-  cell pre-padded via printf widths (``%.3f``, ``%+.3f``, ``%4d``,
-  ``%-15s``, ``%-22s``, ``%-18s``, ``%-9s``, ``%-7s``, ``%-4d``,
-  ``%.4f``, ``%.2f``). Substrings via ``substr(col, 1, N)`` map to
-  Python ``col[:N]``.
-* ``sqlite3 -column -header`` mode (summary h24/d7/lifetime row only):
-  column width = ``max(len(header), max(len(cell)))``, each cell
-  formatted as ``%-Ws``, joined by ``"  "`` (two spaces), trailing
-  spaces preserved, trailing ``\\n`` always emitted (so empty data
-  yields a 12-space line + ``\\n``).
-
-Env knobs honored (also accepted as explicit kwargs to ``main()`` via
-the dispatcher):
-
-* ``MINI_ORK_DB``         — state.db path (default
-  ``${MINI_ORK_HOME:-.mini-ork}/state.db``).
-* ``MINI_ORK_HOME``       — base dir for the default DB path.
-* ``TZ``                  — when subprocess tests compare bash↔py,
-  fixed (typically ``UTC``) so ``datetime(…,'localtime')`` matches.
-
-Schema citations (no column invention — confirmed against these
-migrations before writing):
-
-* ``prompt_win_rates``       — db/migrations/0030_prompt_win_rates.sql
-* ``agent_performance_memory``— db/migrations/0009_memory_namespaces.sql
-                               (column added by 0032_lane_relative_advantage.sql)
-* ``topology_win_rates``     — db/migrations/0034_topology_role_evolution.sql
-* ``bug_reports``            — db/migrations/0029_bug_reports.sql
-* ``role_evolver_log``       — db/migrations/0034_topology_role_evolution.sql

-* ``task_runs``              — db/migrations/0013_task_runs.sql
-
-Parity is enforced by ``tests/unit/test_mini_ork_lifetime_py.py``
-(>=6 cases that drive the LIVE bash subprocess against a temp DB
-seeded by ``db/init.sh`` and compare stdout against the Python port,
-with floats 1e-6 and ints exact).

-"""Recursive-orchestration — Python port of lib/recursive_orchestration.sh.
-
-Faithful port of the six bash public functions that implement bounded
-parent/child mini-ork lineage. The Python port gives callers an in-process
-surface (no `python3` heredoc per call) and gives the parity test a stable
-target to byte-diff against the live bash.
-
-Co-existence model (strangler-fig): bash `lib/recursive_orchestration.sh`
-is the authoritative source. This module mirrors its surfaces exactly.
-Parity is enforced by `tests/unit/test_recursive_orchestration_py.py`
-(>=6 cases that drive the LIVE bash subprocess against a temp DB seeded
-by `db/init.sh` and diff the resulting `run_spawns` / `run_events` /
-`run_artifact_edges` / `merge_decisions` rows against the Python port
-byte-for-byte; floats 1e-6 on `authority_level`, epochs 1s tolerance,
-event_id stem-equal).
-
-Schema citations:
-  - `run_spawns`            — db/migrations/0016_recursive_orchestration.sql

-Pipeline map (bash function → Python):
-  mo_recursive_policy_json    → mo_recursive_policy_json      (env → dict, sort_keys)
-  mo_recursive_emit_event     → mo_recursive_emit_event       (validate JSON → INSERT run_events)
-  mo_recursive_approve_spawn  → mo_recursive_approve_spawn    (transactional: validate gates → counts → INSERT run_spawns + run_events + task_runs UPSERT)
-  mo_recursive_mark_spawn     → mo_recursive_mark_spawn       (UPDATE run_spawns.status, raise on 0 rows)
-  mo_recursive_record_artifact→ mo_recursive_record_artifact  (INSERT run_artifact_edges)
-  mo_recursive_merge_decision → mo_recursive_merge_decision   (INSERT merge_decisions + conditional UPDATE run_spawns.status)
-
-Internal helpers (mirrors of bash underscore-prefixed functions):
-  _mo_recursive_root  → _root         (retained for parity; not consumed)
-  _mo_recursive_db    → _resolve_db   (env precedence: MINI_ORK_DB > MINI_ORK_HOME/state.db > .mini-ork/state.db)
-  _mo_recursive_uuid  → _build_id     (seconds epoch in middle segment)
-  _mo_recursive_bool  → _bool_int     (1|true|yes|on → 1; everything else → 0)
-
-ID format mirror (mirrors bash `_mo_recursive_uuid`):
-    f"{prefix}-{int(time.time())}-{uuid.uuid4().hex[:12]}"
-Seconds resolution is mandatory — `event_id` parity vs bash depends on the

-"""Visible/Hidden Spec Split — Python port of lib/spec-split.sh.
-
-Faithful port of the *deterministic* sub-pipelines of `mo_split_visible_hidden`
-(the inline Python heredoc that extracts the hidden test subset) and the
-verdict-writing half of `mo_run_hidden_suite`. The actual `npx playwright test`
-call stays in bash — it requires a live worktree + Playwright runtime and is
-out of scope for pytest. The Python port gives callers an in-process surface
-and gives parity tests a stable target to byte-diff against the live bash.
-
-Co-existence model (strangler-fig): bash `lib/spec-split.sh` is the
-authoritative source. This module mirrors its sub-pipelines exactly. Parity
-is enforced by `tests/unit/test_spec_split_py.py` (>=6 cases that invoke
-`lib/spec-split.sh` via subprocess — stubbing `mo_run_dir` and `npx` — and
-diff against the Python output byte-for-byte).

-"""Pure-logic port of ``lib/topology.sh::topology_recompute_win_rates``.
-
-Faithful port of the deterministic aggregation logic in
-``lib/topology.sh``. The bash function reads from ``execution_traces`` (and
-left-joins ``workflow_memory``) and upserts aggregated rows into
-``topology_win_rates``. This module lifts the classification rules and the
-win-rate / sample-size math into a regular import so callers (and the
-parity test) can exercise the deterministic core without going through
-SQLite I/O.
-
-The bash function's full pipeline is::
-
-    READ execution_traces + LEFT JOIN workflow_memory
-        ON wm.workflow_version_id = et.workflow_version_id
-    GROUP BY (topology_id, workflow_name, task_class)
-    CLASSIFY each row as win / loss / tie / none via (status, reviewer_verdict)
-    AGGREGATE wins, losses, ties, AVG(cost_usd), AVG(duration_ms)
-    COMPUTE win_rate = wins / (wins + losses), guarded against zero denom
-    COMPUTE sample_size = wins + losses + ties
-
-Public API::
-

-        },
-    )
-
-Each returned ``aggregate_row`` mirrors the columns bash would upsert into

-    ----------
-    traces:
-        Iterable of trace rows. Each row is a Mapping carrying (at minimum)
-        ``workflow_version_id`` and ``task_class``; the function reads
-        ``status``, ``reviewer_verdict``, ``cost_usd`` and ``duration_ms``

-        filters by it via the ``--since`` parameter, which the caller
-        already accounts for before handing rows to the port.
-    workflow_memory:
-        Optional ``{workflow_version_id: {yaml_hash, workflow_name}}``
-        mapping. Equivalent to the bash ``LEFT JOIN workflow_memory``.

-"""Python port of bin/mini-ork-watchdog — per-pass scoring/abort logic.
-
-Strangler-fig parity port of the bash wrapper's ``_watchdog_pass`` heredoc.
-Reads the same ``STATE_DB`` / ``MINI_ORK_HOME`` env contract (lines 25-30 of
-``bin/mini-ork-watchdog``); mirrors the active-run filter, the
-``description LIKE '%status=failure%' OR description LIKE '%status=vacuous%'``
-pattern filter, the ``_tok/_tf/_cos`` cosine-similarity helpers, the
-``round(min(1.0, best_score + fail_boost), 4)`` scoring, the
-``<home>/runs/run-<id>/.stop-requested`` file write (with glob fallback), and
-the ``watchdog_aborts`` insert (with OperationalError-swallowing parity).
-
-Public surface:
-
-    pass_once(db_path, threshold, dry_run, warn_only, mini_ork_home) -> dict
-
-The returned dict matches the JSON printed by the bash heredoc byte-for-byte
-when re-serialised via ``json.dumps(sort_keys=True)``. Floats are 4-decimal
-``round()`` so 1e-6 parity is trivially satisfied.
-
-CLI shim is the only consumer of argparse; the parity test exercises
-``pass_once`` directly so it can drive bash via subprocess and diff real
-``watchdog_aborts`` rows.

-Env knobs honored (also accepted as explicit kwargs):

-  * ``MINI_ORK_HOME``       — runs root (default ``.mini-ork``).
-  * ``MINI_ORK_ROOT``       — repo root (default parent of ``mini_ork/``).
-
-Output format mirrors:
-  * ``review_verdict_for`` echoes just the verdict word with a trailing
-    newline (matches ``sqlite3 ... ;`` output which always appends ``\\n``).
-  * ``review_show`` first emits the header row joined by ``" | "`` with
-    a trailing newline, then a blank line, then the per-issue rows joined
-    by ``" | "`` with a trailing newline (mirrors ``sqlite3 -separator ' | '``
-    plus the bash ``echo`` between the two sections).

-"""Recovery admin: cancel + DAG projection (durable-dag E5).
-
-Design source: ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md`` §8/§9/§11.
-
-Two read/write-light operations that make recovery legible and controllable
-WITHOUT touching the E1–E3 correctness logic (this module only reads their
-tables and calls the E3 lease API as a client):
-
-  * ``cancel_recovery(db, request_id)`` — cancel a pending recovery. Marks the
-    ``recovery_requests`` row terminal (status=failed, failure_class=cancelled),
-    releases the run lease so a fresh recovery can acquire it, and DOES NOT
-    touch ``node_checkpoints`` — prior valid checkpoints stay reusable
-    (E5 acceptance: "recover --cancel leaves prior checkpoints valid").
-
-  * ``recovery_projection(db, run_id)`` — a DAG-shaped view assembled from
-    ``node_checkpoints`` (completed nodes), ``node_attempts`` (per-node attempt
-    history incl. failures), ``recovery_requests`` (the active/last recovery +
-    next action), and ``run_leases`` (who owns the run). Read straight from the
-    tables — never log scraping — so the web UI renders a recovered run as ONE
-    DAG with nested attempts, not two disconnected runs.

-"""circuit_breaker — Python port of lib/circuit_breaker.sh.
-
-Faithful port of ``mo_check_liveness_breaker``: the behavioral liveness gate
-that halts a recipe run burning cost without producing progress. Mirrors the
-embedded Python heredoc in lib/circuit_breaker.sh exactly — same SQL, same
-signal logic, same state-transition rules, same JSON shape.
-
-Co-existence model (strangler-fig): ``lib/circuit_breaker.sh`` stays
-byte-identical. This port gives Python callers an in-process target and
-gives ``tests/unit/test_circuit_breaker_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Env knobs (bash reads these at function entry; the Python port takes them as
-explicit kwargs so callers/tests can pin them — the parity test passes the
-same values it exports to the bash subprocess):
-  MO_CB_ARTIFACT_WINDOW   → artifact_window   (default 3)
-  MO_CB_VERDICT_WINDOW    → verdict_window    (default 3)
-  MO_CB_COST_THRESHOLD    → cost_threshold    (default 1.00)
-  MO_CB_POLICY            → policy            (default "majority"; or/and)
-  MO_CB_COOLDOWN_S        → cooldown_s        (default 1800)
-  MO_CB_DISABLE           → disable           (default False; "1" enables)
-
-``MO_CB_DISABLE`` is honoured at function entry BEFORE any DB work — matches
-the bash lines 109-112 escape-hatch contract. The kwarg and the env combine
-as OR (either triggers the bypass).
-
-Two JSON shapes:
-  - Known run: full diagnostic dict with signals/policy/fired_count/etc.
-  - Unknown run: simpler fail-open shape (run_id, state, verdict, rationale,
-    reason="run_unknown_default_proceed") — bash printf line 110 is the
-    reference. Set-equality is the only safe parity check.
-
-MINI_ORK_DB resolution: bash uses ``${MINI_ORK_DB:?}`` (errors if unset).
-The port raises ValueError when ``db`` is None and MINI_ORK_DB is unset —
-it never silently reads a cwd-relative default.
-
-Public surface:
-    check_liveness_breaker(run_id, db=None,
-                           artifact_window=3, verdict_window=3,

-"""Python port of lib/cleaner.sh — single-shot cleaner agent that runs ON MAIN.
-
-Strangler-fig parity port. Fixes cross-cutting baseline blockers detected by the
-detective: works directly on main via a temp branch, holds an exclusive mkdir
-lock, stashes+restores the user's dirty tree (with the HEAD-moved race guard),
-tries to reuse a recent unmerged cleaner branch, else spawns a one-shot claude
-worker, gauntlet-checks, and squash-merges.
-
-The claude spawn (``_spawn_worker``) and gauntlet run (``_run_gauntlet``) are
-seams — overridable for tests; the default implementations shell out exactly as
-the bash does. Exit codes match the bash verbatim:

-    6 no-commits · 7 required-checks-fail · 10 main-already-clean

-"""Recovery DAG — pure workflow.yaml adjacency data structure.
-
-Parity port: moved verbatim from ``mini_ork/recovery/planner.py`` (SOLID
-SRP split). This module is a pure data structure: it parses
-``workflow.yaml`` (nodes + edges) into adjacency lists and answers
-reachability questions (``descendants``). It has NO env, NO subprocess,
-NO lease, and NO checkpoint-DB concerns — those stay in
-``planner.py`` / ``plan.py``.
-
-Public API (re-exported from ``mini_ork.recovery.planner``):
-
-    load_dag(workflow_yaml_path) -> DAG
-        Parses ``workflow.yaml`` (nodes + edges) into adjacency lists.
-        Returns a ``DAG`` namedtuple with ``node_ids``, ``parents``
-        (id → list of upstream ids), ``children`` (id → list of
-        downstream ids), and ``topo`` (a topo-sorted list).
-
-Topology convention (moved from the planner module docstring):
-
-  Edges in workflow.yaml follow the convention ``from → to`` with
-  ``edge_type`` in ``{depends_on, supplies_context_to, verifies,
-  escalates_to}``. ALL edges contribute to the dependency relation
-  for the closure — ``escalates_to`` and ``verifies`` are still a
-  "this node's output flows into the next node's input" relation at
-  the level the planner needs. ``rollback`` edges are excluded
-  because they are control-flow only (the operator path, not data
-  flow) — including them would mark the WHOLE DAG as the closure
-  whenever a verifier fires.

-"""finalize — Python port of lib/finalize.sh.
-
-Faithful port of ``mo_finalize``: walks ``$MINI_ORCH_DIR/runs/$JOB_ID``
-for epic + iter subdirs, renders a ``COMPLETION_REPORT.md`` with Epics /
-Cache reuse / Cost trace / A-B probe / Next-actions sections, and
-(default ON) auto-merges APPROVE branches via ``mo_auto_merge`` plus a
-cache-reuse summary table when ``mo_aggregate_cache_stats`` is loaded.
-
-Co-existence model (strangler-fig): ``lib/finalize.sh`` stays
-byte-identical. This port renders the same markdown section ordering,
-the same printf column widths, the same float-formats (``.4f`` for cost
-trace totals, ``.2f`` for cache-saved dollars). WS5 cutover: the former
-``bash -c 'source lib/{cache,finalize,auto-merge,pr-create}.sh'`` helpers
-are now the staged native ports — ``mini_ork.cache.run_summary``
-(``mo_cache_run_summary``), ``mini_ork.vcs.auto_merge.auto_merge``
-(``mo_auto_merge``), ``mini_ork.vcs.pr_create.open_pr`` (``mo_open_pr``)
-and ``mini_ork.dispatch.lane_helpers.aggregate_cache_stats``
-(``mo_aggregate_cache_stats``). Parity is enforced by the sibling test
-(``tests/unit/test_finalize_py.py``): >=6 live-subprocess cases; bash
-stdout is the ground-truth reference, deep-diffed against the Python
-report after stripping the volatile ``Generated:`` timestamp and the
-``# Mini-ork completion report — <JOB_ID>`` header line.
-
-DB resolution: bash uses ``${MINI_ORK_DB:-${MINI_ORK_HOME:-.mini-ork}/state.db}``.
-The port raises ``ValueError`` when both ``db`` and ``MINI_ORK_DB`` are
-unset and falls back to ``MINI_ORK_HOME/state.db`` only when ``db`` is
-None and ``MINI_ORK_DB`` is also unset — never silently reads a

-"""Self-healing classification loop — Python port of ``lib/healer.sh``.
-
-Faithful port of the bash decision-engine for failed mini-ork runs: scan the
-``run_dir`` for ``worker.log`` / ``verdict.json`` / ``gauntlet*.log``,
-optionally try a fingerprint match against the ``lessons_bank`` (via
-``lib/memory-retrieve.sh``), optionally call the LLM gateway to classify
-the failure (via ``lib/agentflow-llm-helpers.sh``), optionally persist a new
-lesson (via ``lib/memory-store.sh``), and emit a single JSON line on stdout:
-
-    {"lesson_id": ..., "failure_class": ..., "recovery_action": ...,
-     "recovery_args": ..., "matched": ...}
-
-Line numbers below cite ``lib/healer.sh`` so cross-referencing is trivial.
-
-The bash source stays in place (strangler-fig co-existence). This Python
-function ``decide(epic_id, run_dir)`` is the in-process surface parity tests
-invoke; ``tests/unit/test_healer_py.py`` runs the live bash subprocess on
-identical inputs and asserts byte-identical (rc, stdout, stderr).
-
-NOTE: In the current env the optional sibling scripts (``memory-retrieve.sh``,
-``memory-store.sh``, ``agentflow-llm-helpers.sh``, ``mo-event.sh``) are
-absent. The bash port therefore always reaches the early-escalate branch
-(``lib/healer.sh:83-87``) and emits the hard-coded escalate-human JSON. The
-implementer MUST NOT fabricate LLM-classify parity cases until those siblings
-land; they are out of scope here.

-"""mo_healer_bridge.py — Python port of ``lib/mo-healer-bridge.sh``.
-
-Strangler-fig co-existence: the bash source stays in place; this module
-gives Python callers an in-process target and gives parity tests a
-stable surface to compare against the live bash function via subprocess.
-
-The bash ``mo_run_healer_on_escalate`` function:
-
-  1. Runs ``healer.sh <epic> <run_dir>`` and parses the JSON it prints.
-  2. Switches on ``recovery_action``:
-       cleaner-on-main / rebase-and-retry / wait-and-retry
-         → auto-apply, return 0 on success
-       switch-agent / shrink-scope
-         → emit a brain hint, return 1
-       escalate-human / mark-wontfix / no-op / ""
-         → terminal, return 1
-       anything else
-         → unknown, return 1
-  3. Returns 0 if a recovery was applied (caller re-tries the epic),
-     1 otherwise.
-
-This port reproduces the decision logic and side-effect dispatch. The
-``decide()`` function is pure and exhaustively parity-tested; the
-``mo_run_healer_on_escalate()`` entry point mirrors the bash end-to-end
-behaviour (env override of ``MINI_ORK_ROOT``, rc 0/1).
-
-WS5 cutover: the ``bash lib/healer.sh`` / ``bash lib/cleaner.sh``
-subprocess calls are replaced by the staged native ports
-``mini_ork.recovery.healer.decide`` and ``mini_ork.recovery.cleaner.main``
-(imported below as module seams so tests can monkeypatch them, exactly
-like the bash tests stubbed ``$MINI_ORK_ROOT/lib/*.sh``). The stdout/
-stderr/rc forwarding contract is unchanged: healer's stdout is the
-parsed JSON line (its stderr is discarded, as before), and the cleaner's
-captured stdout/stderr lines are forwarded to this bridge's stderr with
-the same six-space indent.

-"""Recovery plan computation — reuse/rerun/closure sets.
-
-Parity port: moved verbatim from ``mini_ork/recovery/planner.py`` (SOLID
-SRP split). This module owns the **plan computation**: given a run_id +
-workflow.yaml, it reads the E1 checkpoint decisions and walks the DAG
-(``mini_ork.recovery.dag``) to find the **dependency closure** — every
-node that transitively depends on a non-reusable node must rerun,
-because its inputs may now differ. A node whose outputs are reused is
-NOT in the set, even if a parallel sibling failed.
-
-It also owns the ``--status`` pretty-printer (``format_status``) —
-pure read, no dispatch.
-
-Lease wiring, env emission, argv parsing, and ``main()`` stay in
-``planner.py``; everything here is re-exported from there for parity.
-
-Public API (re-exported from ``mini_ork.recovery.planner``):
-
-    compute_recovery(workflow_yaml_path, run_id, db_path, run_dir,
-                      *, recipe=None, task_class=None,
-                      from_node=None) -> RecoveryPlan
-        Computes reuse / rerun / closure sets. ``from_node`` overrides
-        the auto-detected entry (operator override; e.g. force a wider
-        rerun from an earlier known-good point).
-
-    plan_recovery(...) -> RecoveryPlan
-        Thin alias with explicit ``strategy`` argument; resolves the
-        entry node for ``resume | retry | repair | pause``.
-
-    format_status(plan) -> str
-        Pretty-print for ``--status``: reuse / rerun / cost boundary /
-        why-not-reused per node. Pure read, no dispatch.
-
-Design invariants (E2 must not break):
-
-  * Never writes the ``node_checkpoints`` table. Read-only on E1 state.
-  * Never edits ``bin/mini-ork resume`` (cost-pause). Recovery MAY CALL
-    resume (as a child process) but does not extend its surface.
-  * Never introduces leases or turn-resume (E3/E4). The closure is a
-    read-time computation; no scheduling primitive is added.

-"""Recovery planner — E2 of feat/durable-dag.
-
-The planner turns a run_id + workflow.yaml into the **minimal set of nodes
-that must rerun** so a fresh attempt re-uses every valid E1 checkpoint and
-re-dispatches exactly the failed branch (and the nodes that depend on it).
-
-Why this is the load-bearing seam for E2:
-
-  * E1 ``is_node_reusable`` already decides per-node whether the previous
-    attempt is safe to skip. The planner reads that decision and walks the
-    DAG to find the **dependency closure**: every node that transitively
-    depends on a non-reusable node must also rerun, because its inputs
-    may now differ. A node whose outputs are reused is NOT in the set,
-    even if a parallel sibling failed.
-  * The planner is **read-only on disk** — it never writes a checkpoint
-    row, never moves an artifact, never deletes a run-dir. The execute
-    loop is the only writer; the planner just tells it where to start.
-  * The planner is **pure-Python** (no LLM dispatch). ``--status`` calls
-    this module end-to-end and never invokes an LLM lane — the
-    ``status_no_dispatch`` verifier contract enforces that.
-
-Public API:
-
-    load_dag(workflow_yaml_path) -> DAG
-        Parses ``workflow.yaml`` (nodes + edges) into adjacency lists.
-        Returns a ``DAG`` namedtuple with ``node_ids``, ``parents``
-        (id → list of upstream ids), ``children`` (id → list of
-        downstream ids), and ``topo`` (a topo-sorted list).
-
-    compute_recovery(workflow_yaml_path, run_id, db_path, run_dir,
-                      *, recipe=None, task_class=None,
-                      from_node=None) -> RecoveryPlan
-        Computes reuse / rerun / closure sets. ``from_node`` overrides
-        the auto-detected entry (operator override; e.g. force a wider
-        rerun from an earlier known-good point).
-
-    plan_recovery(...) -> RecoveryPlan
-        Thin alias with explicit ``strategy`` argument; resolves the
-        entry node for ``resume | retry | repair | pause``.
-
-    format_status(plan) -> str
-        Pretty-print for ``--status``: reuse / rerun / cost boundary /
-        why-not-reused per node. Pure read, no dispatch.
-
-    main(argv=None) -> int
-        CLI entrypoint mirroring ``mini_ork_resume.main``.
-
-Design invariants (E2 must not break):
-
-  * Never writes the ``node_checkpoints`` table. Read-only on E1 state.
-  * Never edits ``bin/mini-ork resume`` (cost-pause). Recovery MAY CALL
-    resume (as a child process) but does not extend its surface.
-  * Never introduces leases or turn-resume (E3/E4). The closure is a
-    read-time computation; no scheduling primitive is added.
-
-Topology convention:
-
-  Edges in workflow.yaml follow the convention ``from → to`` with
-  ``edge_type`` in ``{depends_on, supplies_context_to, verifies,
-  escalates_to}``. ALL edges contribute to the dependency relation
-  for the closure — ``escalates_to`` and ``verifies`` are still a
-  "this node's output flows into the next node's input" relation at
-  the level the planner needs. ``rollback`` edges are excluded
-  because they are control-flow only (the operator path, not data
-  flow) — including them would mark the WHOLE DAG as the closure
-  whenever a verifier fires.
-
-Module layout (SOLID SRP split — behavior byte-identical parity port):
-
-  * ``mini_ork.recovery.dag``   — the pure DAG data structure + loader
-    (no env, no subprocess, no DB).
-  * ``mini_ork.recovery.plan``  — the recovery plan computation
-    (``RecoveryPlan`` dataclass + closure/first-node selection +
-    ``format_status``).
-  * this module                 — CLI concerns: ``main()``, argv parsing,
-    path resolution, E3 lease/idempotency wiring, and
-    ``_emit_recovery_env``. Everything moved is re-exported here so
-    existing importers (``mini_ork.cli.execute``, tests) keep working.

-This is the bridge between the durable state (E1's ``node_checkpoints.session_ref``

-(``MO_RESUME_SESSION_ID`` in providers.dispatch_model). Before a recovery
-re-dispatches a claude-lane node that stopped mid-conversation, call
-``prepare_node_resume``: it reads the node's last attempt's session id +
-persisted transcript ref, restores the transcript into the (possibly fresh)
-sandbox's claude home, and returns the session id to export.
-
-It is a *continuation optimization*, never a correctness dependency: if there
-is no session id, no persisted transcript, or the restore fails, it returns ""
-and the node re-runs from scratch (E1/E2 already guarantee that is safe).
-
-codex/gemini lanes: these run their own session model and do not use the

-"""coord_registry — Python port of lib/coord_registry.sh.
-
-Faithful port of the three public functions in ``lib/coord_registry.sh``:
-``coord_acquire``, ``coord_release``, ``coord_renew``. Lifts the three
-embedded Python heredocs out of the bash source into one importable module
-while preserving every behavioural detail (exit codes, stderr messages,
-state-file shape, deadlock payload, env cascade, priority lookup).
-
-Co-existence model (strangler-fig): ``lib/coord_registry.sh`` stays
-byte-identical. This port gives Python callers an in-process target and
-gives ``tests/unit/test_coord_registry_py.py`` a stable surface to diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Exit-code contract (mirrors bash exactly):
-    0  — success
-    1  — conflict / unknown / malformed lease id
-    2  — usage / invalid args (missing agent/path/mode, bad mode, bad ttl)
-    3  — coord_renew called by non-holder (a leaked lease_id cannot
-         indefinitely extend someone else's claim)
-    4  — deadlock abort (requester is the lowest-priority participant in a
-         wait-for cycle). Returns a dict payload:
-         ``{"status":"abort","reason":"deadlock","agent":<requester>,
-            "cycle":[<sorted participants including requester>]}``
-
-Stdout/stderr contract (mirrors bash exactly):
-    coord_acquire  → stdout: lease_id (hex) on success, OR JSON deadlock
-                     payload on rc=4. stderr: usage / mode / ttl validation
-                     on rc=2, conflict description on rc=1.
-    coord_release  → stdout: empty. stderr: usage on rc=2, malformed id or
-                     unknown lease id on rc=1.
-    coord_renew    → stdout: empty. stderr: usage on rc=2, malformed id or
-                     unknown/expired lease id on rc=1, not-the-current-holder
-                     on rc=3.
-
-State file env cascade (matches bash ``_coord_registry_state_file``):
-    1. ``COORD_REGISTRY_STATE_FILE``  (explicit override)
-    2. ``${MINI_ORK_RUN_DIR}/state/coord-registry/leases.json``
-    3. ``${MINI_ORK_HOME}/state/coord-registry/leases.json``
-    4. ``${HOME}/.mini-ork/state/coord-registry/leases.json``
-    5. ``/tmp/coord-registry/leases.json``
-
-Cross-process safety: ``fcntl.flock(LOCK_EX)`` on ``<state_file>.lock`` —
-the same per-call pattern the bash heredocs use.
-
-Public surface:
-    coord_acquire(agent, path, mode, ttl=None, state_file=None)
-        -> tuple[str | dict | None, int]
-        Success:        (lease_id, 0)
-        Conflict:       (None, 1)
-        Validation:     (None, 2)
-        Deadlock:       ({"status":"abort", ...}, 4)
-    coord_release(lease_id, state_file=None) -> int
-    coord_renew(agent, lease_id, ttl=None, state_file=None) -> int
-
-Path normalization (matches bash heredoc exactly):
-    "src/api"   → "/src/api"
-    "/src/api/" → "/src/api"
-    "//src//api//" → "/src/api"
-    "/"         → "/" (root preserved)
-
-Prefix overlap is component-aligned: ``src/api`` overlaps ``src/api/x.rs``
-but NOT ``src/ap`` (appending "/" forces strict component alignment).
-
-Agent priority resolution (for deadlock victim selection):
-    1. ``COORD_REGISTRY_AGENT_PRIORITIES`` (comma list, "name=int")
-    2. ``COORD_REGISTRY_AGENT_PRIORITY_<UPPER_SANITIZED>`` env var, where
-       sanitization uppercases alnum and converts others to ``_``.
-       Without this uppercase transform the lookup silently missed for
-       mixed-case agent names (frc-b4/b5 critic fix).
-    3. Default 0.

-"""Python port of lib/version_registry.sh — VersionRegistry + rollback for
-workflows and agents.
-
-Strangler-fig parity port. Each function mirrors the inline-python sqlite3
-block of its bash counterpart byte-for-byte in behaviour:
-
-    version_register        <kind> <payload>            -> version_id (stdout)
-    version_get             <kind> <version_id>          -> JSON or "null"
-    version_current         <kind> <name>               -> JSON of current stable
-    version_rollback        <kind> <name>               -> now-current JSON
-    version_quarantine      <kind> <version_id> <reason>
-    version_can_promote     <kind> <version_id>          -> "true"|"false"
-    version_clear_quarantine <version_id> <approver>
-
-The bash functions print the version_id / JSON on stdout; these return the same
-string so the parity test can compare stdout AND the resulting DB rows.
-
-Non-determinism mirrored from bash: register() mints ``v-<kind[:3]>-<uuid12>``
-when the payload omits ``version_id``, and created_at/promoted_at/quarantined_at
-are ``int(time.time())``. Callers wanting determinism pass ``version_id`` in the
-payload (bash honours ``p.get("version_id")``); ``now`` is injectable here purely
-for tests — bash has no such hook, so the parity test normalises time columns.

-"""Crucible — mini-ork's verified-execution runtime seam.
-
-Crucible is the layer where a candidate change is put under fire: executed in an
-isolated runtime and judged by what the *code actually did*, not by what a model
-said about it.
-
-It is a thin seam over the MIT-licensed `verifiers` engine (Prime Intellect),
-which supplies the runtime primitives (Docker/sandbox execution, environments,
-trace DAGs). mini-ork supplies what sits above:
-
-  * the delivery loop (plan -> execute -> verify -> publish),
-  * the EXECUTION-ANCHORED reward (a judge-approve on a failing test scores 0.0),
-  * multi-node prompt evolution over {planner, implementer, reviewer},
-  * per-customer verified-outcome memory.
-
-Why the seam exists (and why we do not fork): `verifiers` is developed daily and
-its runtime is better than anything we would hand-roll. We depend on it, pin it,
-and keep our value where it actually is -- the loop and the verified outcomes on
-a customer's private repo. See THIRD_PARTY.md for attribution.
-
-Deliberate divergence: `verifiers` scores with rubric/judge Criteria. Crucible
-does NOT. Verdicts here are anchored on execution status; a judge may only veto,
-never approve (see mini_ork.cli.execute.reward_from_status, PR #168).

-"""Native port of the ``mo_runtime_exec`` contract (bash-removal WS7).
-
-Semantics ported verbatim from ``lib/runtime/contract.sh`` + the ``local``
-backend (``lib/runtime/local.sh``), which is the default and the only
-backend the minimal agent scaffold (``mini_ork.agent.minimal``) relies on:
-
-  * run ``cmd`` via ``bash -c`` with ``cwd`` pinned inside the child
-    (the parent process's cwd is never mutated); a missing/unreachable
-    ``cwd`` fails with rc 126, mirroring the bash ``cd || exit 126`` prefix;
-  * stderr is merged into the captured output (bash redirects ``2>&1``
-    into the outfile it then echoes);
-  * the child runs in its own process group, so a timeout TERMs the whole
-    group, grants a 500ms grace, then KILLs it — reaping descendants
-    (subshells, sleeps) — and reports rc 124;
-  * ``timeout`` is in seconds (fractional allowed); 0 waits forever;
-  * trailing ``KEY=VAL`` pairs are injected into the child's environment.
-
-Decision (WS7, recorded here per the bash-removal plan's "decision
-recorded" exit): PORT, not retire and not inline. The contract is small
-but non-trivial (pgid-kill timeout semantics, rc-126 cwd failure, merged
-streams), so it earns a tested home in ``mini_ork/runtime/`` rather than
-an anonymous inline in the agent. The opt-in ``bubblewrap``/``docker``
-backends stay bash-only; both already degrade to ``local`` with a WARN
-when their prerequisites are missing, and this port mirrors exactly that
-fallback rather than silently changing isolation semantics. An unknown
-backend name fails loudly with rc 2, as the bash source-time factory does.

-"""Run-shared virtual drive — the primitive every agent in a run reads/writes.
-
-A ``SharedDrive`` is created once per run and (in a later phase) mounted at a
-fixed path inside every node's ``Workspace`` so state flows node→node/agent→agent
-for the whole run: the target working tree, ``.mini-ork/runs/<id>/`` artifacts,
-and the artifact manifest all live on it. It is the artifact-graph's filesystem
-made real and shared across sandboxes.
-
-The default ``local-bind`` backend is a plain host directory — zero cloud
-dependency, the dev-loop default. Later phases register cloud backends
-(``e2b-volume``/``modal-volume``/``daytona-volume``/``juicefs``) behind the same
-protocol; a provider's native Volume *is* a shared drive, so those backends map
-onto this interface directly.
-
-Design invariants:
-  * **The drive is the pet; sandboxes are cattle.** Durable run state lives here,
-    so ``down()`` defaults to a no-op (it never deletes the host dir) — a crashed
-    teardown must not destroy the run's work. Ephemeral scratch drives opt in via
-    ``ephemeral=True``.
-  * **Containment.** All access is via run-relative paths resolved under the
-    drive root; a path that escapes the root (``..`` traversal or an absolute
-    path) raises ``ValueError`` before any file is touched. Concurrent-write
-    safety across parallel nodes is the CAID ``--owns`` registry's job, layered
-    on top — this module only guarantees a node cannot reach outside the drive.
-
-This module adds NEW surface only; nothing imports it yet. Wiring the drive into
-``RunContext``/``MO_TARGET_CWD`` and the artifact graph is a deliberately separate
-step (it changes every run's working dir). Pure stdlib; no import-time I/O.

-"""Mid-node operator-steering injector — Python port of lib/mid_node_injector.sh.
-
-Faithful port of the deterministic sidecar surfaces of
-``lib/mid_node_injector.sh``: the two pure formatters and the per-tick
-DB→fifo/prompt pipeline that an in-process caller would invoke. The bash
-script stays in place (strangler-fig co-existence) so the production
-sidecar keeps working; this module gives Python callers an in-process
-target and gives ``tests/unit/test_mid_node_injector_py.py`` a stable
-surface to byte-diff against the live bash subprocess.
-
-Co-existence model (strangler-fig): bash ``lib/mid_node_injector.sh`` is
-the authoritative source. Parity is enforced by the live-subprocess
-harness in ``tests/unit/test_mid_node_injector_py.py`` (>=6 cases; floats
-1e-6; DB row-by-row diff via sqlite3 SELECT on operator_steering).
-
-JSON encoding choice (note for reviewers): bash uses ``jq -nc --arg t
-"$body" '{...}'`` which produces compact (no-whitespace) ASCII-compatible
-JSON with jq's native string escaping (Unicode surrogate pairs preserved).
-Python mirrors this with ``json.dumps(..., separators=(',', ':'),
-ensure_ascii=False)`` — the closest semantic match. Edge-case parity
-test (case 3) exercises Unicode + quotes + newlines so any future drift
-between jq and json.dumps surfaces immediately.

-  - The two pure formatters (``_mid_injector_format_claude_user_msg`` /
-    ``_mid_injector_format_codex_prompt``) — full parity required.
-  - The DB→fifo and DB→codex-fork.out per-tick pipeline (one iteration
-    of ``_mid_injector_claude_loop`` / ``_mid_injector_codex_loop``) —
-    full parity required; consumers of these functions must have a
-    reader pre-attached to the fifo to avoid EPIPE (mirrors bash's
-    ``2>/dev/null || true`` on ``printf '%s\\n' "$line" >"$fifo_in"``).
-  - The in-process start_claude/stop loop wrapper — Python uses a
-    daemon thread + ``threading.Event`` to mirror bash's sidecar
-    subprocess; this is a strangler-fig divergence and is NOT covered
-    by parity tests (loop wrapper parity is intentionally out of scope,
-    matching how operator_steering.py isolates the deterministic SQL
-    surface).
-
-Out of scope (intentionally NOT ported — bash keeps owning these):
-  - ``kill -0 / kill -TERM`` parent-process signalling — Python loop
-    wrapper checks ``os.kill(parent_pid, 0)`` for parity with the
-    shell-side ``kill -0`` semantics, but does not actually SIGTERM
-    any process.
-  - ``codex fork <session_id> "..." --output-format text`` subprocess
-    exec — codex_tick appends the formatted prompts to
-    ``{fork_out_dir}/codex-fork.out`` as placeholders (no real exec).
-
-Pipeline map (bash function → Python):
-  _mid_injector_pid_file               → _resolve_pid_path
-  _mid_injector_format_claude_user_msg → format_claude_user_msg
-  _mid_injector_format_codex_prompt    → format_codex_prompt
-  _mid_injector_claude_loop (one tick) → claude_tick
-  _mid_injector_codex_loop  (one tick) → codex_tick
-  mid_node_injector_start (claude)     → start_claude
-  mid_node_injector_stop               → stop

-"""mo-steer CLI surface — Python port of lib/mo-steer.sh.
-
-Faithful port of the bash CLI in ``lib/mo-steer.sh`` that pushes a
-steering message to a live mini-ork worker. The bash script is the
-authoritative source — this module gives Python callers an in-process
-target and gives ``tests/unit/test_mo_steer_py.py`` a stable surface to
-byte-diff against the LIVE bash subprocess (no mocks, no hardcoded
-outputs).
-
-Co-existence model (strangler-fig): bash ``lib/mo-steer.sh`` stays
-byte-identical. The Python port mirrors its CLI semantics exactly. Parity
-is enforced by ``tests/unit/test_mo_steer_py.py`` (eight live-subprocess
-cases that drive ``bash lib/mo-steer.sh <args>`` on identical inputs
-and diff the resulting JSONL envelope + stderr text + exit codes).
-
-Pipeline map (bash CLI → Python):
-  --steer-file= override          → _resolve_steer_paths (override branch)
-  epic-id + job + iter derivation → _resolve_steer_paths (derive branch)
-  MINI_ORK_HOME/runs/<job>/<epic>/iter-N layout
-                                    → _resolve_steer_paths (derive branch)
-  JOB inference from epic prefix   → _infer_job_from_epic
-  (sed -E 's/-[A-Z0-9]+$//' | tr A-Z a-z)
-  Heartbeat mtime liveness         → _check_heartbeat (os.path.getmtime)
-  (stat -f %m / stat -c %Y fork)
-  Heartbeat state=done|aborting    → _heartbeat_state (last-line JSONL pickup)
-  (tail -1 | grep -oE '"state":"[^"]+"')
-  Envelope generation              → steer (json.dumps, atomic single write)
-  ({id, at, from, body})
-  --wait-ack polling               → steer (greps worker.log every 1s, 30s)

-  (5 = heartbeat, 7 = no ack)        7 → RuntimeError)

-"""HITL steering checkpoints — Python port of lib/steering_checkpoint.sh.
-
-A checkpoint lets a recipe pause an in-flight run for human steering, then
-resume once steering arrives. It composes two primitives that already exist:
-``operator_steering`` (the steering message carrier) and the dispatcher's
-plan-status gate (the pause/resume), exactly like ``plan_status=needs_answers``.
-
-Co-existence model (strangler-fig): bash ``lib/steering_checkpoint.sh`` is the
-authoritative source and stays untouched. This module mirrors its public API
-1:1 so Python callers get an in-process surface and
-``tests/unit/test_steering_checkpoint_py.py`` gets a stable target to byte-diff
-against the live bash subprocess.
-
-Shared-DB invariant: the bash library ``source``s ``operator_steering.sh`` to
-inherit ``_operator_steering_db`` / ``_operator_steering_now_ms``. The port
-reuses ``mini_ork.steering.operator_steering._resolve_db`` / ``._now_ms`` for the
-same reason — ``has_unconsumed`` must read the exact ``state.db`` that
-``operator_steering.emit`` / ``.fetch_for`` write to, or it reads an empty DB.
-If ``operator_steering`` is unavailable at import time, we fall through to the
-same env-only path bash uses when the ``declare -F`` probe misses.
-
-Public API (bash function → Python):
-  mo_steering_has_unconsumed   → has_unconsumed(run_id, role='any') -> int
-  mo_steering_checkpoint_mark  → mark(run_id, node_id, reason=None) -> None
-  mo_steering_checkpoint_clear → clear(run_id) -> None
-  mo_steering_checkpoint_status→ status(run_id) -> dict
-  mo_steering_checkpoint_gate  → gate(run_id, node_id='checkpoint', role='any') -> int

-Faithful port of ``lib/anchor_corpus.sh::anchor_corpus_load`` (lines 61-102) and

-is a thin shell wrapper around embedded ``python3`` heredocs that handle parse,
-shape validation, scoring, and TSV reporting. This module lifts those heredocs
-out into native Python with identical semantics:
-
-* ``load_corpus(path)`` mirrors ``anchor_corpus_load`` — validates the corpus
-  JSON shape and returns the parsed dict. Raises :class:`AnchorCorpusShapeError`
-  with the bash-identical stderr message on each failure mode.
-* ``score_recall(findings_path, corpus_path, report_dir=None, floor=...)``
-  mirrors ``anchor_corpus_recall`` — same indeterminate branches, same
-  ``round(recall, 4)``, same TSV layout, same rc semantics; returns a
-  ``(dict, rc)`` tuple so callers don't have to inspect stdout for rc.
-
-Env knobs honored (also accepted as explicit kwargs):
-  * ``MO_CORPUS_RECALL_FLOOR`` (default ``0.8``) — recall floor.
-  * ``MINI_ORK_RUN_DIR`` (default ``"."``) — default ``report_dir`` when
-    ``score_recall`` is called with ``report_dir=None``.

-  write(node_id, status, artifact_path=None) -> int
-        rc=0 on success; rc=2 + matching stderr substring on validation

-          {"nodes": {"<id>": {"status": ..., "artifact_path": ...,

-  can_resume(node_id) -> str
-        Always rc=0. Emits ``"yes\\t<artifact>"`` (TAB separator) on a
-        resumable success-with-artifact-present node, otherwise ``"no"``.
-        Also writes the same string to stdout so grep-parity callers
-        and Python callers share the surface.
-  clear(node_id=None) -> int
-        rc=0 on success; rc=2 if MINI_ORK_RUN_DIR is unset. With no
-        ``node_id``, removes the entire file. With a ``node_id``,
-        removes that node from the JSON ``nodes`` map.
-  summary() -> str
-        rc=0 always. Prints the fixed-column table bash prints
-        (``node_id<24>status<10>age_s<8> artifact`` plus 80-char
-        separator plus sorted data rows) to stdout, then returns it.

-"""Durable DAG checkpoint writer + validity check (E1 of feat/durable-dag).
-
-This module is the **runtime seam** for the per-node checkpoint system
-described in ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md``.
-It is intentionally distinct from ``mini_ork.stores.checkpoint`` (the
-bash-parity status tracker that mirrors ``lib/checkpoint.sh``); that file
-answers "is this node already done?" via a JSON sidecar, while this
-module answers "is this node's work durably reusable on a future attempt?"
-via the ``node_checkpoints`` SQLite table.
-
-The seam's load-bearing contract is the **publication order** in design §4:
-
-    1. caller has already produced every artifact on disk
-    2. ``write_checkpoint`` enumerates them, sha256s each one, builds the
-       manifest, fsyncs them BEFORE the transaction begins
-    3. ONE SQLite transaction inserts the ``node_checkpoints`` row (PK
-       on (run_id, node_id) → INSERT OR REPLACE keeps the latest valid
-       attempt) AND the ``node_attempts`` row
-    4. the row is durable only after the transaction commits
-
-A crash between (1) and (3) leaves no row (window 1 — rerun, correct).
-A crash between (3) and a future re-hash leaves a row whose manifest
-artifacts may be missing/corrupt (window 2 — validity check rejects,
-rerun, correct). Both windows are fail-closed by ``is_node_reusable``.
-
-Public API:
-  CheckpointRecord
-      Frozen dataclass carrying every per-checkpoint value (M8 ISP
-      refactor); an alternative to write_checkpoint's keyword args.
-  write_checkpoint(...) -> int
-      rc=0 on success, non-zero on failure. No exceptions bubble. Caller
-      treats non-zero as "checkpoint not written; node will rerun on next
-      attempt" — by design, fail-closed.
-  is_node_reusable(...) -> bool
-      Always returns a bool. NEVER raises — any exception path is coerced
-      to False (the design rule from §3 + risk_notes: "MUST fail closed").
-  hash_file(path) -> str
-      sha256 hex of a file's bytes; returns "" on any error (caller
-      decides what to do).
-      Convenience for hashing an in-memory blob.
-
-Reader pattern (E2 will use this, E1 just needs it for tests):
-  ``is_node_reusable(db, run_id, node_id, current_input_hash=...,
-                     current_recipe_version=..., current_config_hash=...,
-                     run_dir=...)`` — all three current-* values are the
-  resolution the RUNTIME performed for the new attempt; if any differs
-  from the stored value, the node is NOT reusable and the runtime must
-  rerun it (and its transitive dependents).

-"""Pure-logic port of ``lib/db_open.sh``.

-Faithful Python port of the per-connection SQLite pragma wrapper:
-``mo_sqlite`` (sqlite3 CLI wrapper with PRAGMA busy_timeout injected
-via ``-cmd``) and ``mo_sqlite_py_pragmas`` (emits a Python heredoc
-snippet). The bash wrappers in ``lib/db_open.sh`` stay in place
-(strangler-fig co-existence); this port gives Python callers an
-in-process target and gives tests a stable surface for parity
-verification against the live bash.
-
-Parity note (subtle but load-bearing): bash's ``sqlite3 -cmd
-"PRAGMA busy_timeout=N;"`` ALWAYS emits the pragma's current value
-as the first stdout row before the user's SQL runs. The Python port
-mirrors this by capturing the row from ``con.execute("PRAGMA
-busy_timeout")`` and prepending it to the result list. Skipping that
-row would silently desync stdout shape between the two surfaces
-without breaking any individual query.

-"""Single-writer lease + fencing + idempotent recovery requests (E3).
-
-Design source: ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md``
-§5 (failure-class state machine), §7 (single-writer ownership / fencing tokens).
-Schema: ``db/migrations/0052_run_leases_recovery_requests.sql``.
-
-Two concerns, one module because they share the same concurrency invariant:
-
-1. **Lease + fencing** (``run_leases``). Before any recovery dispatches a node
-   or publishes a checkpoint it must hold the run's lease. A lease is an
-   ``owner_token`` with an ``expires_at``. Any checkpoint/terminal write that
-   presents a token which is not the CURRENT LIVE holder is **rejected** —
-   this is what stops a stale worker (whose token expired and was re-acquired
-   by a newer recovery) from publishing over the top of live work
-   (design §7). Concurrency is serialized by ``BEGIN IMMEDIATE`` so two
-   simultaneous acquirers cannot both win (scenario 6).
-
-2. **Idempotent recovery requests** (``recovery_requests``). The tuple
-   ``(run_id, from_node, strategy)`` is a unique key; a duplicate
-   ``request_recovery`` for the same tuple returns the EXISTING request
-   instead of dispatching a second time. Budget is bounded per request
-   (``budget_usd``) so ``provider_limit``/``repair`` recoveries can never
-   become an unbounded auto-retry loop (design §5).
-
-Time is injectable (``now=``) so tests are deterministic; production callers
-omit it and get ``int(time.time())``. Nothing here raises for a normal
-"can't acquire / not the holder" outcome — those return ``None``/``False`` so
-callers branch on them; only genuinely broken input (missing db) surfaces.

-    is_legacy_checksum(s)                -> True if s is a placeholder (not 64-hex)
-    ensure_table(db)                     -> create/upgrade schema_migrations

-    migrate_verify(dir, db)              -> 0 if all applied checksums match, else 1
-    init_db(db, root)                    -> full db/init.sh port (migrations + views)
-
-Each apply + its schema_migrations record commit together (all-or-nothing), and
-already-applied migrations with a legacy placeholder checksum are re-hashed in
-place, never re-run — mirroring the bash byte-for-byte (applied_at timestamps
-excepted, as bash uses strftime('now')).
-
-Dot-commands: some shipped migrations contain sqlite3 CLI dot-commands
-(`.read "|sh -c '…'"`, `.once`, `.shell`) which ``sqlite3 -bail`` interprets
-but Python's executescript cannot. ``_exec_statements`` re-implements the
-subset the shipped migrations use: `.read "|<cmd>"` runs the shell pipeline
-(with MINI_ORK_DB / MINI_ORK_ROOT exported, exactly like db/init.sh) and
-inlines its stdout as SQL, `.read <path>` inlines a file, `.once <path>`
-redirects the next statement's rows to a file, and `.shell <cmd>` runs a
-shell command. Any other dot-command fails the migration (rolled back),
-matching `sqlite3 -bail` aborting on an unrecognised command.

-"""pattern_store — Python port of ``lib/pattern_store.sh``.
-
-Faithful port of the PatternRecord storage, query, and mining CLI in
-``lib/pattern_store.sh``. The bash script is the authoritative source —
-this module gives Python callers an in-process target and gives
-``tests/unit/test_pattern_store_py.py`` a stable surface to byte-diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Co-existence model (strangler-fig): bash ``lib/pattern_store.sh`` stays
-byte-identical. The Python port mirrors its CLI semantics exactly,
-including the bash-private ``_pattern_ensure_table`` DDL (which differs
-slightly from migration 0011's CHECK — see SCHEMA NOTE below). Parity
-is enforced by ``tests/unit/test_pattern_store_py.py`` (>=7 live-
-subprocess cases that drive ``bash lib/pattern_store.sh <args>`` on
-identical inputs and diff rc + stdout + DB row contents).
-
-Public API (1:1 with bash CLI):
-  store(payload, *, db_path=None, on_new_hooks=None) -> tuple[str, bool]
-      Mirror of ``pattern_store <json_payload>``. ``payload`` is a
-      Python dict (already-parsed JSON — the bash CLI takes a JSON
-      string and parses it itself; the port narrows the API to a dict
-      so callers cannot accidentally pass malformed JSON). Returns
-      ``(pattern_id, is_new)`` mirroring the ``pid|new/updated``
-      sentinel that bash prints internally and then strips before
-      echoing the bare pid on stdout. ``on_new_hooks`` is an optional
-      list of zero-arg-or-one-arg callables invoked on a new pattern
-      with the (pid, payload) pair, matching bash's per-process
-      ``_PATTERN_ON_NEW_HOOKS`` array (errors swallowed via ``|| true``
-      to mirror bash).
-  query(*, db_path=None, min_frequency=1, output_type="") -> list[dict]
-      Mirror of ``pattern_query [--min-frequency N] [--output-type T]``.
-      Returns a list of row dicts (sqlite3.Row → dict) sorted by
-      frequency DESC. The bash CLI emits a JSON-encoded list on
-      stdout; the port returns the parsed list directly. Tests
-      JSON-decode bash stdout and diff lists element-wise.
-  mine_from_traces(*, db_path=None, window="7d", min_cluster=3) -> int
-      Mirror of ``pattern_store_mine_from_traces --window Nd --min-cluster N``.
-      Parses ``Nd``/``Nh`` (default ``7d`` → 604800s), queries
-      ``execution_traces`` for (task_class, status) clusters whose
-      count >= ``min_cluster`` within the window, and upserts one
-      ``pattern_records`` row per cluster with deterministic
-      ``pat-<sha256[:12]>`` ids. Returns the count of clusters
-      upserted (mirrors bash's stdout ``print(written)``).
-  on_new_register(callable) -> None
-      Mirror of ``pattern_on_new <hook_fn_name>``. Appends to the
-      module-global ``_ON_NEW_HOOKS`` registry (intentionally
-      cross-call persistent; bash's registry is per-subprocess-fresh
-      — this is a documented API divergence). The registry is exposed
-      for tests via ``pattern_store._ON_NEW_HOOKS.clear()``.
-
-DB path resolution mirrors bash:
-    ${MINI_ORK_DB:-${MINI_ORK_HOME:-$(pwd)/.mini-ork}/state.db}
-
-Per-process schema-init guard mirrors bash's ``_MO_PATTERN_SCHEMA_INIT``
-env var: a module-global bool ensures ``_ensure_table`` runs the
-``CREATE TABLE IF NOT EXISTS`` exactly once per process, regardless of
-how many ``store()`` / ``mine_from_traces()`` calls follow.
-
-SCHEMA NOTE: The bash's ``_pattern_ensure_table`` DDL declares
-``CHECK(output_type IN ('adr','verifier_addition','workflow_change',
-'prompt_change','best_practice_rule','other'))`` — six values
-including ``'other'``. Migration 0011 in db/migrations declares a
-five-value CHECK that OMITS ``'other'``. When the parity test
-initialises a fresh DB via ``db/init.sh``, the 5-tuple CHECK wins
-(because ``CREATE TABLE IF NOT EXISTS`` is a no-op against an already-
-migrated table). Inserts with ``output_type='other'`` therefore FAIL
-on both sides equivalently — the parity test asserts the rejection,
-not the storage of 'other'. This is a known schema drift in bash; the
-port faithfully mirrors it (the same coercion runs, the same insert
-fails).
-
-TIMESTAMP NOTE: All ``first_seen`` / ``last_seen`` writes use SQLite's
-``strftime('%Y-%m-%dT%H:%M:%fZ','now')`` inside the INSERT/UPDATE
-SQL, matching bash byte-for-byte. Python's ``strftime('%f')`` produces
-6-digit microseconds while SQLite's ``%f`` produces 3-digit fractional
-seconds — using SQLite avoids the format drift entirely. The
-WHERE-clause comparison in ``mine_from_traces`` uses
-``strftime('%Y-%m-%dT%H:%M:%S.000Z', <since_epoch>, 'unixepoch')``
-which mirrors bash's
-``datetime.datetime.utcfromtimestamp(since_epoch).strftime('%Y-%m-%dT%H:%M:%S.000Z')``
-byte-for-byte.

-"""Central backend selector for mini-ork brain libraries — Python port of lib/policy_store.sh.
-
-The store-port seam that ``lane_router``, ``process_reward``, and
-``gradient_extractor`` go through to learn whether the live store is
-SQLite (default; eng-team, preserved behavior) or Postgres (v0.2-pt36
-stub, intentionally aborting before any sqlite3 call so the real
-researcher-side PG impl can swap the stub without re-architecting
-callers).
-
-Co-existence model (strangler-fig): bash ``lib/policy_store.sh`` is the
-authoritative source and stays untouched. This module mirrors its
-public API 1:1 so Python callers get an in-process surface and
-``tests/unit/test_policy_store_py.py`` gets a stable target to byte-diff
-against the live bash subprocess.
-
-Public API (bash function → Python):
-  mo_store_backend                 → backend() -> str
-  mo_store_assert_sqlite           → assert_sqlite() -> None
-  mo_store_db_path                 → db_path() -> str
-  mo_store_py_connect_snippet      → py_connect_snippet() -> str
-  mo_store_py_pragmas_snippet      → py_pragmas_snippet() -> str
-
-Exit-code parity: bash returns 64 (EX_USAGE) for an unknown
-``MO_STORE_BACKEND`` and 78 (EX_CONFIG) for ``assert_sqlite`` on a
-non-sqlite backend. The Python port raises ``SystemExit(N)`` with the
-same integer so subprocess-style callers see an identical rc. Bare
-``ValueError`` / ``Exception`` would silently diverge — a caller doing
-``subprocess.run(..., check=False)`` on a Python wrapper would see rc=1
-instead of 64/78.
-
-Snippet byte-exactness: bash emits snippet lines via
-``printf '<literal>\\n'``. The Python port returns the EXACT same string
-(e.g. ``'import sqlite3\\ncon = sqlite3.connect(db)\\n'`` for sqlite,
-``'con.execute("PRAGMA busy_timeout=5000")\\n'`` for sqlite pragma).
-Returning as a string — NOT via ``print()`` — avoids Python's implicit
-trailing newline breaking byte-for-byte parity against the live bash
-subprocess.
-
-Default-value parity: bash uses ``${VAR:-default}`` (fires when VAR is
-unset OR empty). Python's ``os.environ.get("VAR", "default")`` only
-fires when VAR is unset. We use ``os.environ.get("VAR") or "default"``
-so empty-string env vars collapse to the default the same way they do
-in bash.

-"""mini-ork dispatch tracker — Python port of lib/runs-tracker.sh.

-  mo_runs_resolve_claude_session_id → resolve_claude_session_id

-
-The bash library is the authoritative source. This module mirrors its
-SQL byte-for-byte (including the COALESCE+rationale append and the single-
-connection `last_insert_rowid()` extraction) so callers have an in-process
-alternative entry point and parity tests have a stable target.
-
-Co-existence model (strangler-fig):
-  bash `lib/runs-tracker.sh` stays untouched (this port never replaces it
-  in the call path). Parity is enforced by `tests/unit/test_runs_tracker_py.py`
-  which invokes the live bash library via subprocess and SELECT-diffs the
-  resulting rows against the Python port.
-
-Rationale-column append semantics (mirrors bash exactly):
-  Bash:  rationale = COALESCE(rationale, '') ||
-                    CASE WHEN rationale IS NULL OR rationale = '' THEN '' ELSE ' | ' END ||
-                    'iter:' || '<escaped verdict>'
-  Same SQL template is reproduced here; on the first append (rationale NULL
-  or empty) no ' | ' separator is emitted, so the column starts with
-  'iter:FAIL' / 'final:APPROVE'. On subsequent appends the ' | ' separator
-  joins them ('iter:FAIL | iter:WARN'). Verified against the live bash row
-  diff in tests/unit/test_runs_tracker_py.py::test_update_progress_parity.
-
-Module-level _SCHEMA_INIT_DB is a per-DB-path set (mirrors bash's session-
-wide _MO_RUNS_SCHEMA_INIT=1 guard but keyed on the actual DB file so tests
-with fresh per-case temp DBs still exercise the CREATE statements). The
-guard prevents repeated DDLS on hot paths (audit F-01: ~300K wasted
-sqlite3 forks/day at 100K dispatch volume).
-
-Forbidden-fallbacks compliance:
-  Bash silently swallows sqlite3 errors via 2>/dev/null. The Python port
-  surfaces them via `warnings.warn(...)` (matching the row-diff contract —
-  best-effort audit trail — while honoring no-silent-recovery). The warn
-  fires AFTER the SQL is emitted; row content is unchanged either way
-  unless the connection itself failed.

-"""safety_events — Python port of lib/safety_events.sh.
-
-Faithful port of the bash CLI in ``lib/safety_events.sh`` that writes
-and queries safety incident records in ``state.db:safety_events``. The
-bash script is the authoritative source — this module gives Python
-callers an in-process target and gives
-``tests/unit/test_safety_events_py.py`` a stable surface to byte-diff
-against the LIVE bash subprocess (no mocks, no hardcoded outputs).
-
-Co-existence model (strangler-fig): bash ``lib/safety_events.sh`` stays
-byte-identical. The Python port mirrors its CLI semantics exactly.
-Parity is enforced by ``tests/unit/test_safety_events_py.py`` (>=6
-live-subprocess cases that drive ``bash lib/safety_events.sh <args>`` on
-identical inputs and diff rc + stdout + DB row contents).
-
-Pipeline map (bash CLI → Python function):
-  mo_safety_event_emit <tripwire> <severity> <evidence> [run_id] [recipe]
-                            → emit(tripwire_id, severity, evidence_json,

-"""Durable session-transcript store for turn-level resume (durable-dag E4).
-
-Design source: ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md`` §6.
-
-The claude CLI keeps each conversation as a jsonl transcript under
-``~/.claude/projects/<project-slug>/<session_id>.jsonl`` (the slug is the
-absolute cwd with path separators turned into dashes). ``claude --resume
-<session_id>`` replays that transcript to continue the SAME conversation at the
-turn it stopped. But the transcript lives in the *worker's* home — if the
-sandbox/worker dies, the transcript dies with it and ``--resume`` fails.
-
-This module makes turn-resume survive that death:
-
-  * ``persist_session(run_dir, session_id)`` copies the live transcript into
-    the run dir (``<run_dir>/sessions/<session_id>.jsonl``) at checkpoint and
-    on a recoverable failure, returning a portable ``session_ref``.
-  * ``restore_session(run_dir, session_ref, session_id)`` copies it back into
-    ``~/.claude/projects/<slug>/`` on a fresh sandbox BEFORE the resume, so the
-    CLI finds the transcript it expects.
-
-Everything is best-effort and fail-soft: a missing transcript returns ""/False
-rather than raising, because turn-resume is a *continuation optimization* — if
-it can't happen, the node re-runs from scratch (still correct, just not cheap).

-"""Tool-call receipts for safe replay during recovery (durable-dag E4).
-
-Design source: ``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md`` §6.
-Schema: ``db/migrations/0053_tool_receipts.sql``.
-
-When a recovered node replays work, a side-effecting (non-idempotent) tool
-call it already made — a git commit, a file write, an external POST — must NOT
-run a second time. This store records a *receipt* (the canonical input hash +
-the captured output) the first time such a call completes; on replay the guard
-``replay_or_invoke`` returns the receipt WITHOUT re-invoking (scenario 8).
-Read-only tools are marked ``idempotent`` and re-invoke fresh by default.
-
-Scope note (honest): the claude lane runs its OWN internal tool loop inside the
-``claude --print`` subprocess, so mini-ork cannot intercept claude's per-tool
-Read/Write/Bash calls to replay them. This store is for the side effects
-mini-ork itself performs at node boundaries (the publisher commit, checkpoint
-writes, external calls a recipe drives) and is the durable substrate a future
-in-loop interceptor would write through. The design's "read-only may replay /
-non-idempotent must not" rule is enforced here for those callers.

-"""Python port of lib/auto-merge.sh — squash-merges APPROVED epic branches into

-
-Strangler-fig parity port of mo_auto_merge + its mutex and untracked-stash
-helpers. Git and sqlite3 operations shell out (the function IS a git+DB
-orchestrator); the ported logic is the epic-collection + verdict gating + branch
-resolution + squash-merge-under-mutex + DB status transition + worktree cleanup.

-
-The mutex is the same mkdir-based cross-job lock (stale-PID takeover); the
-critical section serialises `git merge --squash` + commit across parallel jobs.
-
-Observability (WS5): bash mirrors every status line to stdout AND
-`$job_run_dir/merge.log` via `tee -a`, and appends the raw stdout/stderr of
-the rebase/checkout/merge/commit git commands to the log (`>> merge_log 2>&1`).
-Pass ``log`` (tee-style status lines) and/or ``log_raw`` (file-only command
-output) callables to reproduce that surface; the default ``None`` keeps the
-port silent (its parity-suite behaviour).

-stopped writing to its log. Mirrors the shell logic in
-``lib/worktree-guard.sh`` exactly — same 1Hz polling cadence, same mtime

-verification against the LIVE bash subprocess (no mocks, no hardcoded
-outputs).
-
-Env knobs (bash reads these at function entry; the Python port honours them
-when the explicit kwargs are ``None``):
-  ``MO_WORKTREE_GUARD_MAX_WAIT_S``  → ``max_wait_s``       (default ``30``)
-  ``MO_WORKTREE_GUARD_STABLE_S``    → ``stable_window_s``  (default ``5``)

-"""Behavioral verifier — execution-anchored live checks of observable surfaces.
-
-A *behavioral* verifier exercises a user- or data-journey surface **live** and
-returns a three-valued, execution-anchored verdict:
-
-    PROVEN     — every declared check and metamorphic relation held live.
-    REFUTED    — a check failed against a *reachable* surface (the code is wrong).
-    UNVERIFIED — the surface could not be exercised (unreachable, no observable
-                 declared, budget exhausted, or a relation we cannot yet
-                 evaluate). This is abstention — NOT a pass.
-
-Why three-valued and not binary: a verifier that turns "I couldn't check" into a
-green is a false-complete, and false-completes are exactly what the verifier is
-built to eliminate. Abstaining loudly protects precision (cf. the measured
-0-false-completions guarantee) at the cost of recall, which is the correct trade
-for a gate.
-
-P0 implements ``surface="api"`` only: probe a staging endpoint with httpx (the
-requester is injectable so tests need no network), assert status + an optional
-JSON shape, and check metamorphic relations that need no gold output — a single
-request/response is enough to anchor an oracle (RESTOR, 2607.23963; metamorphic
-REST testing, 2605.28321). ``ui`` / ``journey`` surfaces return UNVERIFIED here;
-they register their handlers in P1/P2 via :func:`register_surface_handler`.
-
-Process-seam contract: ``mini_ork/cli/verify.py`` dispatches a ``verifiers/*.py``
-script as a subprocess and treats **exit-0-with-evidence as PASS**. So a
-behavioral verifier must print its verdict JSON to stdout (non-empty evidence)
-and exit 0 ONLY on PROVEN. UNVERIFIED must not exit 0 — :func:`main` maps
-PROVEN->0, REFUTED->1, UNVERIFIED->``MO_BEHAV_ABSTAIN_EXIT`` (default 1 =
-conservative; set to 0 only for an advisory-only verifier). The full
-three-valued verdict always lands in the emitted JSON for the ranking scorecard
-(P3).
-
-Import-time contract: pure stdlib. ``httpx`` and ``yaml`` are imported lazily
-inside the functions that need them, so importing this module never pulls a
-third-party dependency and does no I/O beyond registering the built-in ``api``
-surface handler in a dict.

-A :class:`VerifierCard` is a static, file-backed description of a single
-verifier — its kind, surface, cost, recipe pointer, and IRT-GRM-style quality
-statistics. The catalog module exposes:
-
-- :func:`load_cards` — the only I/O boundary; parses one or more
-  ``*.card.yaml`` files lazily and validates each against
-  ``schemas/verifier_card.schema.json`` if ``jsonschema`` is installed;
-- :func:`card_score` — deterministic IRT-GRM-inspired score,
-  ``discrimination * consistency * (1 / (1 + cost)) - fuzz_penalty``;
-- :func:`rank_verifiers` — sorts by score desc, then cost asc (stable sort
-  falls back to file order, which is sorted before parsing).
-
-Import-time contract: pure stdlib. ``yaml`` and ``jsonschema`` are imported
-lazily inside :func:`load_cards`, so importing this module never pulls a
-third-party dependency and performs no I/O. This mirrors the import-time
-contract of :mod:`mini_ork.verify.behavioral`.

-  POST /dispatch  →  record what was proposed, what was chosen, and by whom; mint the run-id
-

-    the system proposed X · a human chose Y · Y turned out (better | worse | the same)
-
-That is a labelled example. Today `conductor_decisions` records only the final choice, so a

-adds `proposed_*` + `decided_by` + `task_run_id`; this endpoint is what fills them.

-  · a (lane, task_class) pair with fewer than MIN_SAMPLES runs is returned with

-  · every rate ships with a Wilson interval. A bare 75% from n=4 invites belief the sample
-    cannot support.
-  · we do NOT return the conductor's predicted_score. Until enough decisions carry a
-    realized_score, that number is unfalsifiable, and putting it on screen would be exactly the

-load-bearing artifacts: the contextual bandit's learned lane policy
-(lane_domain_advantage / lane_region_advantage), GEPA's outcomes
-(prompt_win_rates / promotion_records), and the failure memory (2,009 failure_links).
-
-Gradients were visible; whether a gradient ever WON or got PROMOTED was not. That
-is the difference between watching a loop run and watching it learn.

-Every SELECT below names columns read off `PRAGMA table_info` — none are guessed.

-# Eval judge — code-fix
-
-You are grading one completed `code-fix` run: a single-patch code change that
-should pass typecheck, tests, and reviewer gates. Judge the **whole trajectory**,
-not just the final diff — a green run can still hide a broken or scope-violating
-change.
-
-Anchor each axis to concrete evidence from the trajectory, not vibes:
-
-- **correctness** — Does the patch actually fix the stated problem? Weigh the
-  typecheck/test verifier verdicts heavily; a run whose verifiers failed is not
-  correct no matter how clean the diff reads.
-- **completeness** — Is the whole task addressed (all files/edges the plan
-  named), with no requirement silently dropped?
-- **groundedness** — Are the changes grounded in the real repo (the diff matches
-  the plan and the trajectory's tool calls), with no fabricated files or claims?
-- **safety** — Did the run stay in scope — no unrelated edits, no destructive or
-  out-of-bounds actions, no gate-evasion? Treat scope violations as a hard
-  downgrade.
-
-Score every axis 0.0–1.0 and return the strict JSON envelope requested below the
-rubric. No prose outside the JSON.

-"""verifiers/metamorphic.py — Layer-2 metamorphic verifier for code-fix.
-
-Runs task-supplied metamorphic relations against a target function using the
-gold-free engine in ``mini_ork.learning.metamorphic``. Emits a Layer-0-compatible
-JSON verdict on stdout, so its result feeds the execution reward like any other
-verifier. Execution-grounded: a relation "fails" only when running it produces a
-real counterexample.
-
-Spec sourcing (declarative, deterministic): set ``MO_METAMORPHIC_SPEC`` to a
-Python file exposing:
-  - TARGET:      a single-argument callable (the function under test)
-  - SEED_INPUTS: an iterable of seed inputs
-  - RELATIONS:   a list of mini_ork.learning.metamorphic.MetamorphicRelation
-
-No spec → a clean ``vacuous`` verdict (Layer 0 excludes it; it never inflates or
-deflates the reward). This keeps the verifier a safe no-op until a task provides
-relations. LLM-proposed relations (arXiv 2603.24774) are the richer follow-on:
-the proposer emits RELATIONS, and this same execution oracle certifies them.
-
-Exit codes: 0 pass / vacuous, 1 fail (a metamorphic relation was violated).

-# verifiers/test.py — run the project's test suite and emit structured JSON.
-#
-# Python port of test.sh (bash-removal WS8). Same rc semantics, env vars, and
-# output text.
-#
-# Gating is BASELINE-RELATIVE (delta), not absolute-green: a patch is judged on
-# whether it makes the suite WORSE, not on whether the suite is perfectly green.
-# Pre-existing failures and broken test environments (wrong interpreter, shadow
-# installs, collection/import errors in untouched code) are NOT the patch's fault
-# and must not roll back a correct fix. This mirrors SWE-bench's own
-# FAIL_TO_PASS / PASS_TO_PASS semantics and fixes the false-reject that discarded
-# correct cheap-model patches (see docs: verifier net-negative diagnosis).
-#
-# Decision table (post = current patched tree, base = HEAD worktree without patch):
-#   post green                         -> pass  (nothing to prove)
-#   post red,  base ALSO red           -> pass  (pre-existing/env breakage, uninformative)
-#   post red,  base green              -> fail  (the patch introduced a regression)
-#   post red,  base indeterminate      -> fail  (fall back to absolute; never hide a regression)
-#
-# Exit codes:  0 pass   1 fail   (callers also read the JSON "pass" field)
-#
-# Env vars:
-#   MINI_ORK_TEST_CMD    explicit command to run (skips auto-detect)
-#   MINI_ORK_HOME        path to .mini-ork/ dir (default: .mini-ork)
-#   MINI_ORK_RUN_ID      current run id (used in log path)

-# Frontier LLM Research
-
-This recipe creates one evidence-preserving research document from at least 200
-LibWit/arXiv records published in 2026. It separates work into three layers:
-
-1. Deterministic collection, ranking, and source sharding.
-2. Ten model workers, each limited to its own 20-paper artifact.
-3. Schema validation, technique deduplication, and deterministic Markdown assembly.
-
-The final `aggregation.md` retains one two-part entry per source: an
-evidence-bound summary paragraph followed by `How to write a proper prompt:`
-with one to twenty practical instructions. `unified-techniques.md` then merges
-cross-source duplicates while retaining source identifiers.
-
-## Required environment
-
-The recipe never stores the LibWit bearer token in a recipe, prompt, or run
-artifact. Configure it in the invoking shell or an approved secret manager:
-
-```bash
-export ARXIV_API_TOKEN='...'
-export MINI_ORK_LIBWIT_API_BASE='https://arxiv.libwit.ai/api'
-```
-
-`MINI_ORK_LIBWIT_API_BASE` defaults to the URL above. The collector calls the
-documented batch endpoint once, fails closed if it cannot collect 200 distinct
-2026 records, and does not spend model tokens on a partial corpus.
-
-## Run
-
-```bash
-bin/mini-ork providers status --workflow recipes/frontier-llm-research/workflow.yaml
-bin/mini-ork validate --recipe frontier-llm-research
-bin/mini-ork run frontier-llm-research recipes/frontier-llm-research/example-kickoff.md
-```
-
-For a graph-only check that makes no network or model calls:
-
-```bash
-MINI_ORK_DRY_RUN=1 bin/mini-ork run frontier-llm-research recipes/frontier-llm-research/example-kickoff.md
-```

-paragraph and a second `How to write a proper prompt` paragraph containing one
-to twenty concrete instructions. Build one final Markdown aggregation: retain
-every source summary, deduplicate overlapping techniques, and include every
-unique technique with source identifiers.
-
-## Scope
-
-- Only `recipes/frontier-llm-research/**` and the run-local
-  `.mini-ork/runs/<id>/` artifacts are in scope. The source set is only the 2026
-  LibWit/arXiv paper records returned by the dated collection plan; no generic
-  web results or invented citations.
-
-## Success Criteria
-
-- The minimum corpus is 200 distinct unversioned arXiv URLs, each with a publication
-  date, retrieval date, source ID, title, and abstract or metadata evidence.
-- The required artifacts are `source-corpus.json`, ten `source-shard-*.json` files,
-  ten `summary-shard-*.json` files, `technique-rollup.json`,
-  `unified-techniques.md`, and `aggregation.md`.
-
-## Verification Command
-
-- Run `python3 recipes/frontier-llm-research/lib/research_pipeline.py
-  verify --aggregation "$MINI_ORK_RUN_DIR/aggregation.md"`; it must confirm
-  at least 200 source sections and one `How to write a proper prompt:` section
-  for every source section.

-Rules:
-- Produce exactly one summary for every source in the shard; preserve its IDs,
-  URLs, dates, rank, and topics exactly.
-- Write one concise factual paragraph per paper using only its supplied title,
-  abstract, and metadata. State a limitation when the abstract does not support
-  a stronger claim.
-- `prompt_instructions` is the second required paragraph in structured form:
-  include 1 to 20 directly actionable instructions, each specific to the paper.
-- Do not invent results, benchmark numbers, source URLs, or dates.
-- `shard_techniques` must consolidate duplicated instructions within this shard
-  while preserving every supporting `source_id`.

-Read only the declared `technique_rollup` artifact. Produce a Markdown document
-that unifies duplicate techniques across shards and adds every genuinely unique

-replacement for per-paper summaries.
-
-Requirements:
-- Group recommendations by the work they help with: goal framing, context and
-  evidence, planning, inference-time effort, tools and verification, revision,
-  and structured output.
-- Each recommendation must be concrete enough to paste into a prompt or a task
-  contract. Preserve source IDs in parentheses for every recommendation.
-- Merge semantically duplicate instructions into one stronger instruction with
-  all supporting source IDs. Keep distinct instructions distinct.
-- Include a short limitations section explaining that source-level claims are
-  based on the retrieved LibWit metadata and abstracts unless a record states
-  otherwise.
-- Do not introduce claims or sources absent from the rollup.

-# Prompt Graph Loop
-
-`prompt-graph-loop` turns a natural-language request into verified,
-human-approved final summaries and an aggregation document without replacing
-MiniOrk's scheduler, artifact ledger, policy, or harness adapters.
-
-## Topology
-
-| Workflow stage | MiniOrk node | Durable artifact |
-| --- | --- | --- |
-| PromptIntake | `prompt_intake` | `prompt-brief.json` |
-| SemanticFlowExtractor | `semantic_flow_extractor` | `semantic-signals.json` |
-| Evidence collection | `source_researcher` | `source-corpus.json` |
-| RecursivePlanComposer | `recursive_plan_composer` | `agent-graph.json` |
-| DraftExecutor | `draft_executor` | `draft-artifact.md` |
-| VerifierGate | `verifier_gate` plus `graph_contract_gate` | `verification-report.json` |
-| ReflectionLoop | `reflection_loop` | `refinement-prompt.md` |
-| HumanFeedbackGate | `human_review_packet` plus `human_feedback_gate` | `human-decision.json` |
-| Summary finalization | `summary_finalizer` | `final-summaries.json` |
-| Aggregation | `aggregation_document` | `aggregation.md` |
-
-Each consumer receives a materialized, hash-checked copy of only its declared
-inputs. `source_researcher` makes corpus requirements explicit: a request for
-200 current sources is incomplete until it has 200 distinct source URLs. The
-two recursive edges declare a five-iteration policy: verifier
-findings return to the graph composer; a `revise` human decision returns to
-semantic extraction.
-
-## Runtime Boundary
-
-This recipe is executable for its first graph pass and enforces artifact
-integrity plus approval-gated finalization. MiniOrk's current generic executor compiles
-recursive edges but does not yet replay them as an automatic iteration loop.
-An outer controller should use the existing recursive orchestration and
-`steering_checkpoint` seams to start the next pass from `refinement-prompt.md`
-or `human-decision.json`. This is deliberate documentation of a runtime gap,
-not permission to treat a reviewer model as human approval.
-
-## Human Decision
-
-The review packet asks an operator to provide this file in the run directory:
-
-```json
-{
-  "decision": "approved",
-  "approver": "alice"
-}
-```
-
-For revisions, use:
-
-```json
-{
-  "decision": "revise",
-  "approver": "alice",
-  "feedback_delta": "Add a source-validation node before drafting."
-}
-```
-
-`human_feedback_gate` validates this file deterministically. Only `approved`
-passes the gate and unlocks summary finalization and aggregation. A valid `revise`
-decision is retained as evidence but exits non-zero, so finalization is blocked. In a dashboard or
-product integration, pair the packet with MiniOrk's `steering_checkpoint` and
-an operator-steering message so the outer driver pauses before the decision and
-starts the next bounded iteration with the retained feedback. The current recipe
-declaration records that boundary but does not turn a reviewer model into a
-human approver.
-
-## Run
-
-```bash
-MINI_ORK_DRY_RUN=1 bin/mini-ork run prompt-graph-loop \
-  recipes/prompt-graph-loop/example-kickoff.md
-```
-
-Use the normal MiniOrk lane configuration to select Codex, Claude Code, Kimi,
-or another harness for the planner, worker, researcher, reviewer, and reflector
-roles. Harnesses remain execution adapters; MiniOrk owns the graph, artifact
-handoffs, verification, and repair policy.

-Constraints:
-
-- Identify assumptions separately from supported claims.
-- Record every source URL, publication date, and retrieval date in a source corpus.
-- Keep the graph to no more than eight agentic nodes before deterministic gates.
-- Present the graph and draft for human approval before finalizing summaries.
-- On revision, preserve valid graph nodes and change only the parts named by
-  verifier findings or human feedback.

-# `self-migrate` — verify-gated, integration-point-first self-migration
-
-Closes one **integration fork** (a bash↔Python seam) at a time as a *single
-complete unit*, so no half-migrated seam is ever left behind. Propose-not-commit:
-emits a reviewable diff + a static-feature ledger + a verdict; never applies to
-main or retires an entrypoint on the real checkout.
-
-Full design + the integration-point map + the feature manifest:
-[`docs/migration/self-migrate-feature-manifest.md`](../../docs/migration/self-migrate-feature-manifest.md).
-
-## Why forks, not libs
-Bottom-up leaf migration *splits* integration points — it makes a Python module
-native but leaves the paired bash entrypoint (and every lib/test/UI ref to it)
-live. This recipe advances a **single frontier root→down**: above it pure Python,
-below it pure bash, nothing half-open. A fork closes only when every inbound ref
-is repointed and the bash entrypoint retires.
-
-## The pipeline (per fork)
-1. **seam_mapper** (opus) → `integration-map.json` — every outbound seam + every
-   inbound ref (incl. `bin/`, `lib/`, tests, sandbox, web UI).
-2. **static_feature_ledger** (opus) → `static-feature-ledger.json` — classify
-   every behavior **static** (cheap + byte-parity verifiable — the moat) vs
-   **agentic** (a cost + verifiability liability + a cost-down candidate). This
-   ledger is the migration's strategic payload.
-3. **migrator** (codex) → `self-migrate.diff` — make Python sole, repoint every
-   inbound ref, retire the bash entrypoint in the diff.
-4. **verify** — `pre-retirement-parity.sh` captures byte parity while the Bash
-   oracle still exists · `parity.sh` rechecks the migrated behavior · `feature-acceptance.sh`
-   (the end-to-end feature probe + pytest + pyright) · `ledger-shape.sh` (the
-   ledger is complete, every agentic row has a cost-down `opportunity`) ·
-   `fork-closure.sh` (the retired entrypoint and every runtime reference are gone).
-5. **reviewer** (opus) → `verdict.json` — `pass == parity ∧ acceptance ∧
-   ledger_complete ∧ no_dangling_edge`.
-
-## Lane policy (set in `$MINI_ORK_HOME/config/agents.yaml`)
-| role | lane | backoff |
-|---|---|---|
-| implementer (`migrator`) | **codex** | codex |
-| mapper / ledger / reviewer | **opus** (`opus_lens`) | codex |
-| discovery lens (non-critical) | **GLM** (`glm_lens`) | codex |
-
-## Run it
-```bash
-export MINI_ORK_ROOT="$PWD" MINI_ORK_HOME="$PWD/.mini-ork" MO_TARGET_CWD="$PWD"
-export MO_ALLOW_FRAMEWORK_CWD=1 MO_FORK=verify      # self-edit + name the fork
-"$MINI_ORK_ROOT/bin/mini-ork" run self-migrate recipes/self-migrate/example-kickoff.md
-```
-Recommended order (by blast radius, from the integration map): **verify** (cleanest)
-→ reflect → classify → plan → cli → **execute** (the monster: 4 outbound seams incl.
-`context_assembler` 786L, 37 inbound refs — last).
-
-## Feature-acceptance probes
-`gates/feature_acceptance.sh <fork|feature>` — the end-to-end probe suite that is
-the migration's real finish line (unit-parity alone misses feature breaks).
-`gates/feature_acceptance.sh all` runs every probe.

-# Close the `verify` integration fork
-
-## Goal
-Close the `verify` fork: make `mini_ork/cli/verify.py` the sole
-implementation, repoint every inbound reference to `bin/mini-ork-verify`, and
-retire the bash entrypoint — as a reviewable diff, not applied to main.
-
-The `verify` fork was the cleanest proof case (0 outbound seams — the Python
-side was already runtime-native). This file remains the root-relative template
-for evaluating another fork; all six original top-level forks are now closed.
-
-## Fork
-- **fork:** `verify`
-- **python entrypoint:** `mini_ork/cli/verify.py`
-- **bash entrypoint to retire:** `bin/mini-ork-verify`
-
-## Inbound references to resolve
-- `bin/mini-ork` — repoint the top-level run path away from the Bash verifier
-- `mini_ork/cli/execute.py` — repoint its `bin/mini-ork-verify` invocation to the Python verify module
-- `mini_ork/cli/main.py` — replace dynamic `_bin(root, "verify")` dispatch with the native module
-- `mini_ork/cli/verify.py` — self-reference (delegation shim)
-- `tests/e2e/test_e2e_recipe_code_fix.sh` — repoint to `python3 -m mini_ork.cli.verify`
-- `tests/integration/test_bin_verify.sh` — convert the bash-oracle parity test to standalone Python
-- `tests/unit/test_mini_ork_verify_py.py` — drop the live-bash parity dependency once the oracle is gone
-
-## Acceptance criteria
-- `verifiers/parity.sh` — cross-runtime byte-parity holds (bash==python) BEFORE
-  the bash entrypoint is retired in the diff.
-- `verifiers/pre-retirement-parity.sh` — durable parity evidence is captured
-  before the migrator can retire the Bash entrypoint.
-- `verifiers/feature-acceptance.sh` — `gates/feature_acceptance.sh verify` passes,
-  `tests/unit/test_mini_ork_verify_py.py` green, pyright 0 on the port.
-- `verifiers/ledger-shape.sh` — `static-feature-ledger.json` classifies every
-  behavior in `mini_ork_verify.py` (static vs agentic), agentic rows carry a
-  cost-down `opportunity`.
-- `verifiers/fork-closure.sh` — the Bash entrypoint is absent and executable/runtime paths contain no surviving `bin/mini-ork-verify` reference.
-- No surviving reference to `bin/mini-ork-verify` anywhere in the diff'd tree.
-
-## Verification commands
-
-- `python3 -m pytest tests/unit/test_mini_ork_verify_py.py -q -p no:cacheprovider`

-# Cost/verifiability lens (non-critical, cheap first pass)
-
-You run on a cheap lane (GLM), in parallel, as a NON-critical pre-pass for the
-authoritative `static_feature_ledger`. The panel tolerates your failure; if your
-lane throttles (GLM 429 "Fair Usage"), the run backs off to codex and proceeds
-without you. So be fast and cheap, not exhaustive.
-
-## Job
-Skim the fork's module + `integration-map.json` and flag the OBVIOUS
-cost/verifiability signals, so the opus ledger node can focus its judgment:
-
-- Which functions clearly call an LLM (grep for `claude`, `llm_dispatch`,
-  `cl_*`, `subprocess`→a model) → **agentic candidates**.
-- Which are clearly pure sqlite/string/math logic → **static candidates**.
-- Any function that is agentic today but looks mechanically deterministic
-  (fixed transform, no genuine judgment) → **cost-down candidate** worth the
-  ledger node's attention.
-
-## Output
-A short list to `${MINI_ORK_RUN_DIR}/cost-verifiability-lens.md`:
-
-```
-agentic:   <fn> — <why (file:line)>
-static:    <fn> — <why>
-cost-down: <fn> — agentic now, looks deterministic because <...>
-```
-
-Keep it under ~20 lines. You are a hint generator, not the authority — the
-opus ledger node makes the final call and its `static-feature-ledger.json` is
-what the `ledger_verifier` checks.

-# Migrator — close the fork in a reviewable diff (propose-not-commit)
-
-You close ONE integration fork, working in the isolated worktree. Inputs:
-`integration-map.json` (every seam + ref) and `static-feature-ledger.json`
-(the static/agentic classification). Produce the migration as a unified diff at
-`${MINI_ORK_RUN_DIR}/self-migrate.diff` — do NOT apply to main, do NOT retire
-any entrypoint on the real checkout.
-
-## The three moves — resolve the WHOLE fork, leave no dangling edge
-
-1. **Make the Python side sole.** Rewire every outbound seam to native:
-   - AST-verify the target port is already native (real `subprocess`/`Popen`
-     nodes, not docstring mentions) before importing it. If it is NOT native,
-     port its logic first.
-   - Replace `_bash_lib_call("X","fn",args,env)` with `from mini_ork.ported
-     import X; try: X.fn(...) except Exception: 0` — the `try/except` mirrors
-     `_bash_lib_call`'s `|| echo 0`; a side-channel must never crash the caller.
-   - **Stdout discipline:** if the native fn `print()`s (some ports do, as a
-     bash-heredoc parity artifact), wrap the call in
-     `with contextlib.redirect_stdout(io.StringIO()):` so it does not leak into
-     the caller's stdout. Check the port for a real `print()` before deciding.
-
-2. **Repoint every inbound ref** from `integration-map.json`:
-   - Tests that invoke `bin/mini-ork-<fork>` as a parity oracle → convert to
-     standalone Python tests (golden values captured from the parity-verified
-     output), or repoint to `python3 -m mini_ork.ported.mini_ork_<fork>`.
-   - Lib / script / sandbox / UI refs → point at the Python entrypoint or its
-     module.
-
-3. **Retire the bash entrypoint IN THE DIFF** — `git rm bin/mini-ork-<fork>` and
-   drop its `runtime-select` fallback — ONLY once every inbound ref is repointed.
-   If any `close_blocker` remains, do NOT retire it; emit a partial diff and say
-   so in the verdict.
-
-## Hard rules
-- One fork per run. Absolute paths. Stay inside the scope the `scope_gate` allows.
-- Preserve exact behavior + return contracts; the parity verifier diffs you
-  against the live bash on the real state.db.
-- Every function you change must have a row in `static-feature-ledger.json`.

-# Reviewer — is the fork actually closed, with nothing left dangling?
-
-You are the final judgment before the proposal is published. You have: the
-`self-migrate.diff`, the `integration-map.json`, the `static-feature-ledger.json`,
-and the five verifier reports (pre-retirement parity, post-change parity,
-feature-acceptance, ledger-shape, fork-closure). Use
-opus-level scrutiny — this is the moat.
-
-## Decide `pass` on four questions, each grounded in evidence
-
-1. **Parity** — did byte-parity vs the bash oracle hold on the LIVE state.db
-   (not a dry-run, not an empty fixture)? A 0-vs-0 parity on an empty db is weak
-   evidence; note it if the write path was never exercised.
-2. **Feature-acceptance** — does the affected feature's end-to-end probe pass?
-   Unit-parity is necessary but not sufficient (a rewire can pass unit-parity yet
-   break the feature — e.g. leak stdout). The probe is the real gate.
-3. **No dangling edge** — cross-check the diff against `integration-map.json`:
-   is EVERY inbound ref repointed? If the bash entrypoint is retired, grep the
-   diff'd tree for any surviving `bin/mini-ork-<fork>` reference. One survivor =
-   fail.
-4. **Ledger complete** — does every changed function have a ledger row, and is
-   each agentic flag's `opportunity` filled? The ledger is the deliverable, not
-   an afterthought.
-
-## Output
-Emit `verdict.json` with `parity_pass`, `acceptance_pass`, `no_dangling_edge`,
-`ledger_complete`, `files_changed`, and `pass == (all four)`. If you reject, say
-exactly which edge/feature/row failed and what the migrator must change — this
-escalates to rollback, and the operator reads your reason.
-
-Do not rubber-stamp. A confident-but-wrong "closed" here ships a dangling
-reference into main.

-# Seam mapper — map ONE integration fork's full surface
-
-You are mapping a single **integration fork** so it can be closed completely,
-with no dangling edge left behind. The fork is named in the kickoff (e.g.
-`verify` → the `bin/mini-ork-verify` ↔ `mini_ork/cli/verify.py`
-seam).
-
-## Produce `${MINI_ORK_RUN_DIR}/integration-map.json`
-
-Reason about the seam — do not apply a fixed template. Compute, from the actual
-repo:
-
-1. **Outbound seams** — every place the Python entrypoint shells to bash:
-   `_bash_lib_call(...)`, `subprocess.run([... "source lib/X.sh" ...])`,
-   `bin/mini-ork-*` invocations. For each: the bash symbol, the args/env passed,
-   any side-effect (db write, file, stdout the caller captures).
-2. **Inbound refs** — every reference to the bash entrypoint `bin/mini-ork-<fork>`
-   across `bin/`, `lib/`, `mini_ork/`, `scripts/`, `tests/`, and the web UI
-   (`mini_ork/web/`). Classify each: test/parity-oracle, lib caller, script,
-   sandbox, UI route.
-3. **runtime-select coupling** — how `lib/runtime-select.sh` delegates this fork
-   and what the bash-fallback path is.
-
-```json
-{
-  "fork": "verify",
-  "outbound_seams": [
-    {"symbol": "lib/X.sh::fn", "args": "...", "side_effect": "db|file|stdout-captured|none", "port_exists": true, "port_native": true}
-  ],
-  "inbound_refs": [
-    {"path": "tests/integration/test_bin_verify.sh", "kind": "test|parity-oracle|lib|script|sandbox|ui", "how": "invokes bin/mini-ork-verify"}
-  ],
-  "runtime_select": {"delegates": true, "fallback": "bin/mini-ork-verify"},
-  "close_blockers": ["<what must be resolved before the bash entrypoint can retire>"]
-}
-```
-
-## Rules
-- **The `bin/` and `mini_ork/web/` scans are non-negotiable.** The failure mode
-  this whole recipe exists to prevent is retiring an entrypoint while a lib,
-  test, or UI route still references it.
-- Use `codegraph_explore` / grep to ground every edge in a real file:line. Do
-  not infer edges you cannot cite.
-- A fork cannot be declared closeable while any `close_blocker` is unresolved.

-# Static-feature ledger — the migration's strategic payload
-
-This is not bookkeeping. It is the cost/verifiability audit that makes the
-migration worth more than a port. mini-ork's moat is **cost-down at constant
-verified correctness**, and those two goals share one root cause:
-
-| class | cost | verifiability |
-|---|---|---|
-| **static** (deterministic logic) | ~0 tokens | un-gameable — byte-parity vs an oracle |
-| **agentic** (LLM call) | tokens per call | weak — an LLM-judge is gameable |
-
-## Produce `${MINI_ORK_RUN_DIR}/static-feature-ledger.json`
-
-For **every** function/behavior in the fork being migrated (from
-`integration-map.json` + the module source), emit one row. Classify
-deliberately — this is a decision, not a description:
-
-```json
-{
-  "fork": "verify",
-  "features": [
-    {
-      "feature": "aggregate_win_rates",
-      "class": "static | agentic | integration",
-      "verifiability": "byte-parity | test | llm-judge | none",
-      "cost": "zero | tokens-per-call",
-      "decision": "keep-static | make-static | must-stay-agentic | plumbing",
-      "opportunity": "<if agentic: can it become deterministic, or be gated by a deterministic check? if so, how. else null>"
-    }
-  ],
-  "summary": {"static": 0, "agentic": 0, "integration": 0, "cost_down_candidates": 0}
-}
-```
-
-## Rules
-- **static** confirmed → a unit of the moat proven. Keep it static.
-- **agentic** flagged → a cost AND verifiability liability. Fill `opportunity`:
-  is there a deterministic replacement, or a deterministic gate that makes the
-  agentic step verifiable? Pure static→agentic is almost never right — say so if
-  the code drifted that way.
-- **integration** → a seam; note whether it carries an LLM or is pure plumbing.
-- Every behavior the `migrator` will touch MUST appear here — the
-  `ledger_verifier` fails the run if a changed function has no ledger row.
-- Ground each row in a real file:line. Do not invent features.

-the local Qwen student.
-
-Why GRPO is well-defined HERE and not in the mini-ork router: the router's arms
-are different closed-API model families (codex/kimi/minimax/opus) with no shared
-weights and no gradients — so the router is a contextual bandit, correctly. The
-student is a single weight set on a GPU we rent, so GRPO is exactly the right tool.
-
-How it works:
-  * Prompt: (instruction=system, input=user) — the same route context the SFT
-    data uses. The student must emit a `route: <lane>` line.
-  * G rollouts: GRPOTrainer samples `--num-generations` completions per prompt on
-    the *local* model (the cheap kind of G-sampling — a rented GPU by the minute,
-    NOT G calls to frontier APIs per task).
-  * Reward (RLVR, VERIFIABLE — no learned reward model): route_of(completion) is
-    checked against the gold route. The gold is mini-ork's reward_g-derived
-    best-lane for that slice (it is what the SFT `output` already encodes), so
-    the reward is grounded in real outcomes, deterministically checkable.
-  * GRPO computes the group-relative advantage over the G rewards (mean-baseline,
-    the same baseline the router's bandit borrows — but here it drives a real
-    policy gradient through the LoRA), with a KL leash to the reference model.
-  * Gate: held-out route accuracy via scripts/local_eval_route.py — NOT train loss
-    (per the standing rule: gate on held-out eval).
-
-Run (RunPod GPU; ~$0.70-class single-epoch job, same infra as the SFT autopilot):
-  python scripts/grpo_route_train.py \
-    --model Qwen/Qwen3-4B-Instruct-2507 \
-    --data route_train.json --heldout route_test.json \
-    --out grpo-out --num-generations 8 --max-steps 500
-
-CPU-validate the reward + data plumbing (no GPU, no trl) before renting a GPU:
-  python scripts/grpo_route_train.py --self-test

-harness-tested (see tests/unit/test_mini_ork_execute_py.py).
-The LIVE per-node dispatch path (dispatch_node with the real llm_dispatch seam) can

-researcher node through the ported live path and checks the wiring end-to-end:

-  * the output artifact was written to the run dir,
-  * cost was charged to task_runs.cost_usd,
-  * the node returned success.
-
-This is the gate that must pass before flipping the LIVE dispatch default to python
-(the deterministic default is already validated). It costs one cheap dispatch.

-Probes the load-bearing numerical + path claims in README.md against
-the live repo state. Catches the 90% class of drift surfaced in the
-2026-06-05 audit (docs/audits/20260605-readme-claims-audit.md).
-
-Python port of scripts/readme-claim-check.sh (bash-removal Phase 4) — same

-
-Exit codes:
-  0  no drift
-  1  mechanical drift detected — README is out of sync with the repo
-  2  invocation error (missing dep, missing README, etc)

-Usage:
-  scripts/readme_claim_check.py              # full check
-  scripts/readme_claim_check.py --verbose    # print every probe
-  scripts/readme_claim_check.py --json       # JSON output (CI-friendly)
-
-Env knobs:
-  MO_README                 path to README.md (default: ./README.md)
-  MO_README_SKIP_MIGRATIONS 1 to skip migration-count check
-  MO_README_DRIFT_TOLERANCE 0|integer — how far off a count can be

+# rlm-shared-brain-smoke.sh — prove the SHARED brain (lib/decision_service.sh
+# + lib/lane_router.sh + bin/mini-ork-execute GRPO writers) routes each
+# objective_domain slice to its own learned lane, NOT a single global argmax.
+#
+# Vehicle: seed two known objective slices (code-delivery + book-gen) on the
+# same (task_class, node_type) with orthogonal winning lanes (codex vs
+# minimax), exercise the live recompute + GRPO writers, then verify each
+# slice's learned winner is preserved even when the OTHER slice floods the
+# database.
+#
+# Slice isolation assertions:
+#   1. seeded        — each objective_domain has its own (tc, node_type, lane)
+#                      winner, with reward_g above peers by a clear margin
+#   2. recomputed    — lane_router_recompute_advantages groups by
+#                      (objective_domain, task_class, node_type) and reports
+#                      a per-group winner that matches the seed expectation
+#   3. independent   — after flooding code-delivery, the book-gen slice's
+#                      winner is STILL minimax_lens (objective_domain
+#                      isolation prevents code-delivery bias from leaking)
+#   4. decision      — decision_service.decide(node, tc, od) returns a valid
+#                      routing JSON with coalition_ok=true, sample_size>=5,
+#                      reward_estimate in the seeded range
+#   5. closure_gate  — scripts/learning-loop-closure-gate.sh exits 0 against
+#                      the seeded temp DB

-"""scripts/router_replay_eval.py — D6 offline replay evaluation.
-
-Replay logged execution_traces from a state.db and score whether the
-bandit estimator (single-sample baseline + z-score + UCB) picks a
-higher-reward lane than the legacy greedy (relative_advantage DESC)
-selector, on a held-out slice split.
-
-No new inference — pure read against the existing execution_traces +
-agent_performance_memory + lane_domain_advantage tables.
-
-The replay is intentionally deterministic: a seeded RNG plus a pinned
-train/eval split coefficient (default 70/30) so two replays against the
-same state.db produce identical win-rate numbers. CI smokes against
-tests/fixtures/router_replay_fixture.db; live runs against
-.mini-ork/state.db.
-
-Output (stdout, one JSON object):
-    {
-      "db": "<path>",
-      "n_traces_total": <int>,
-      "n_eval": <int>,
-      "n_train": <int>,
-      "old_winrate": <float>,
-      "new_winrate": <float>,
-      "delta": <float>,
-      "seed": <int>,
-      "split": <float>,
-      "ucb_c": <float>,
-      "notes": "<short string>"
-    }
-
-Exit codes:
-    0 — success (always, even when delta is negative; the script reports
-        the answer, it does not gate it).
-    1 — invocation error (missing DB, malformed args).
-
-Implementation notes:
-    - Train/eval split is grouped by (objective_domain, task_class,
-      node_type) slice so the held-out set never overlaps with a lane's
-      training history. Without the grouping, a lane with no train rows
-      could appear "lucky" on every eval row it owns.
-    - The legacy selector reads agent_performance_memory (the global
-      pool) ordered by relative_advantage DESC, runs_count DESC. The
-      bandit selector uses the lane_domain_advantage z_score_advantage
-      with a UCB bonus; when no z-scored row exists the lane drops
-      back to the legacy order so cold-start paths match.
-    - Both selectors project onto (task_class, node_type) the trace
-      belonged to, so we measure within-slice routing quality — not
-      cross-slice leakage.

+# scripts/smoke-cn-bridge.sh — reference smoke harness for the v1 CN bridge.
+#
+# Reference TEMPLATE every ContextNest <-> mini-ork PR must follow per
+# the Smoke Test Standard in ContextNest's
+# docs/roadmap/epics/agent-context-pack.md. It exercises the real system
+# end-to-end against a live ContextNest server and produces a human-
+# readable evidence file at tmp/smoke-evidence/cn-bridge-<timestamp>.md.
+#
+# Tests covered:
+#   1. Happy path: planner injection block contains real CN atoms
+#   2. Worker prefetch: file written + content non-empty
+#   3. CN-down: graceful degradation (planner finishes, empty CN block)
+#   4. MO_DISABLE_CN=1: zero CN calls
+#   5. CN-slow: silent no-op without crash
+#
+# Usage:
+#   bash scripts/smoke-cn-bridge.sh                       # default kickoff
+#   KICKOFF=kickoffs/<other>.md bash scripts/smoke-cn-bridge.sh
+#   CN_BASE_URL=http://localhost:28080 bash scripts/smoke-cn-bridge.sh
+#
+# Exit codes:
+#   0   all assertions passed
+#   1   one or more assertions failed (evidence file lists which)
+#   78  prerequisite missing (e.g. kickoff path, lib/cn_client.sh)
+#
+# Bash-only on purpose so any reviewer can read it without Rust/Python
+# tooling beyond what mini-ork already requires.

 ```bash
 # From the repo root:
-python3 -m pytest -q
+bash tests/smoke.sh
 ```
 
-The suite is pure Python (the bash test layers were removed in the
-2026-07 bash-removal — see `docs/plans/2026-07-26-bash-removal-plan.md`).
-`pyproject.toml` sets `pythonpath=["."]` and `testpaths=["tests"]`.
-
-## Layout
-
-| Path | Contents |
-|---|---|
-| `tests/unit/` | Unit tests for `mini_ork/*` modules (`*_py.py`) |
-| `tests/` (root) | Integration-style suites (dispatch, recovery, web smoke, run artifacts, …) |
-| `tests/integration/` | Cross-component integration tests |
-| `tests/e2e/` | End-to-end flows |
-| `tests/optimize/` | GEPA/optimizer tests |
-| `tests/live/` | Live-provider tests (skipped without creds) |
-
-## Conventions
-
-- DB-backed tests bootstrap the schema with
-  `mini_ork.stores.migrate.init_db(db_path, root=repo)` — no subprocess,
-  ~1s. Use a `tmp_path` db per test.
-- Tests that drive CLIs prefer `python -m <module>` subprocesses or
-  in-process `main(argv)` calls.
-- The `conftest.py` autouse fixture snapshots/restores `os.environ` and
-  cwd — never leak either (a past leak of `.mini-ork/state.db` into the
-  suite cwd poisoned later tests).
-- Long-history: parity tests that compared the Python port against the
-  retired bash twins were converted to plain unit tests in Phase 3
-  (2026-07-27); expectations are semantic, not recorded goldens.
-
-## CI
-
-`.github/workflows/ci.yml` runs ruff (blocking + advisory), pytest on
-3.11/3.12 (sharded `unit-a`/`unit-b`/`rest`), the UI typecheck, and the
-web smoke suite. The merge green-gate is `python3 -m pytest -q` (scope
-per task with `MINI_ORK_TEST_CMD`).
+Exit 0 = all checks passed or were cleanly skipped.
+Exit 1 = at least one check failed (see `[FAIL]` lines).
+
+---
+
+## Test Files
+
+| File | What it tests | Requires |
+|---|---|---|
+| `tests/smoke.sh` | Deps, DB init, bash syntax, shellcheck | `sqlite3`, `jq`, `git`, `bash 4+` |
+| `tests/unit/test_memory.sh` | `lib/memory.sh` CRUD assertions | `lib/memory.sh` + `db/init.sh` |
+| `tests/unit/test_dispatch.sh` | `lib/dispatch.sh` error-handling | `lib/dispatch.sh` + `db/init.sh` |
+| `tests/integration/test_bin_spawn.sh` | `mini-ork spawn` CLI lineage, child workspace, and child cap | `sqlite3`, `git`, dry-run mode |
+| `tests/e2e/test_e2e_recursive_orchestration.sh` | root -> child -> grandchild recursive orchestration | `sqlite3`, `git`, dry-run mode |
+| `tests/security/test_sec_recursive_spawn_limits.sh` | depth, authority, and orphan-parent spawn blocking | `sqlite3`, `git` |
+
+---
+
+## Running Individual Tests
+
+```bash
+bash tests/unit/test_memory.sh
+bash tests/unit/test_dispatch.sh
+bash tests/integration/test_bin_spawn.sh
+bash tests/e2e/test_e2e_recursive_orchestration.sh
+bash tests/security/test_sec_recursive_spawn_limits.sh
+```
+
+All test scripts follow the same convention:
+- `[OK]` — assertion passed
+- `[SKIP]` — precondition not met (dependency not yet present); not a failure
+- `[FAIL]` — assertion failed; exit 1
+

+	bash tests/smoke.sh
+	bash tests/unit/test_memory.sh
+	bash tests/unit/test_dispatch.sh
+```
+
+---
+
+## Skips vs Failures
+
+A `[SKIP]` means a precondition was not met — typically because another
+agent is still building the dependency being tested. Skips are **not**
+counted as failures. The smoke test exits 0 if all results are `OK` or
+`SKIP` with zero `FAIL`.
+
+This design lets CI run cleanly on a partial repo while agents are still
+in-flight.
+
+---
+
+## Adding New Tests
+
+1. Create `tests/unit/test_<module>.sh` using the same `_ok` / `_fail` /
+   `_skip` pattern as the existing unit tests.
+2. Add a guard at the top: skip if the library under test is not present.
+3. Use a `mktemp -d` isolated `MINI_ORK_HOME` — never write to the caller's
+   `.mini-ork/` directory.
+4. Clean up with `rm -rf "$TMP_DIR"` at the end.
+5. Add a row to the table in this README.
+
+The guard + skip pattern means tests can be added for features not yet
+implemented — they stay in the repo as forward documentation and flip to
+`[OK]` automatically once the implementation lands.

-"""Suite-wide test isolation.
-
-Many ported ``main()`` functions mirror the bash entrypoints by exporting
-process env (``os.environ["MINI_ORK_HOME"]``, ``MINI_ORK_DB``, ``MINI_ORK_RUN_ID``,
-``MINI_ORK_ROOT``, …). That is correct for the real CLI (process-scoped) but, when
-a test calls ``main()`` in-process, the mutation persists into the shared
-``os.environ`` and leaks into later tests. A downstream bash-parity test then
-spawns bash with ``{**os.environ, ...}`` and inherits a stale (often deleted)
-``MINI_ORK_HOME``/``MINI_ORK_DB`` from the earlier test — so bash and the port
-diverge and the parity assertion fails. Each such test passes in isolation but
-fails in the full suite (the CI-only, single-process failure mode).
-
-This autouse fixture snapshots and restores ``os.environ`` and the working
-directory around every test, isolating that leakage suite-wide.

-Python port of ``tests/integration/test_gate_grounded_rejection.sh``.
-
-That bash script sources all 6 gate libs (``coalition_gate.sh``,
-``krippendorff_alpha_gate.sh``, ``citation_verifier_mechanical.sh``,
-``refute_or_promote_gate.sh``, ``honest_ci_gate.sh``, ``gates_common.sh``)
-into one shell and drives each gate's hard-block + pass path, asserting the
-shared ``mo_grounded_rejection`` side-effect: exactly one row lands in
-``grounded_rejections`` on a hard-block verdict, and zero rows land on a
-pass/indeterminate verdict.
-
-Wiring note (read before extending this file): none of the 5 ported gate
-functions (``coalition_gate.check_panel_coalition``,
-``krippendorff_alpha_gate.check_panel_alpha``,
-``citation_verifier_mechanical.check_citations``,
-``refute_or_promote_gate.check_fabrication_survival``,
-``honest_ci_gate.check_ci_widths``) call ``gates_common.emit`` themselves —
-each port's own docstring says so explicitly ("Python callers wire rejection
-through their own substrate"). That wiring is NOT yet implemented anywhere
-else in the Python side of this repo (no caller module invokes it either).
-This test therefore performs that wiring itself, verbatim-matched against
-each bash gate's inline glue that calls ``mo_grounded_rejection`` after
-printing its verdict JSON:
-
-  lib/coalition_gate.sh:246-256               (gate="coalition")
-  lib/krippendorff_alpha_gate.sh:230-238       (gate="krippendorff_alpha")
-  lib/citation_verifier_mechanical.sh:232-240  (gate="citation_verifier")
-  lib/refute_or_promote_gate.sh:242-250        (gate="refute_or_promote")
-  lib/honest_ci_gate.sh:280-290                (gate="honest_ci")
-
-This proves gates_common.py's write path + each port's verdict-generation
-reproduce the SAME grounded_rejections outcomes the bash integration test
-asserts, given the same fixture data — but it does NOT prove a production
-caller wires them today. See the migration audit for the precise couplings
-that still block deleting the bash gate cluster.

-"""Python port of ``tests/integration/test_meta_orchestrator_loop.sh``.
-
-The bash smoke exercises 7 phases of the meta-orchestrator compound loop by
-sourcing ``lib/epic_graph.sh``, ``lib/topology.sh`` and ``lib/role_evolver.sh``
-and driving ``bin/mini-ork-conductor`` + ``bin/mini-ork-lifetime`` against
-``.mini-ork/state.db``. Both bin entrypoints already delegate to their Python
-ports via ``lib/runtime-select.sh::mo_runtime_maybe_delegate`` whenever
-``MINI_ORK_RUNTIME`` is unset or ``python`` (the default) — so the bash test
-was, in practice, already exercising ``mini_ork.orchestration.conductor``
-and ``mini_ork.orchestration.lifetime`` for phases 6-7. This port drives
-those two modules directly (in-process, ``main(db=..., root=...)``) instead
-of shelling out, and drives the three ``lib/*.sh`` equivalents
-(``mini_ork.orchestration.epic_graph``, ``mini_ork.orchestration.topology``,
-``mini_ork.learning.role_evolver``) for phases 1-5.
-
-Phase-by-phase correspondence (same behavioral assertions, not weakened):
-
-  1. Seed root + dependent epic via epic_dependencies
-     -> direct sqlite3 INSERT (same rows the bash heredoc inserts).
-  2. epic_graph_ready_now picks only the unblocked root
-     -> mini_ork.orchestration.epic_graph.ready_now()
-  3. epic_graph_on_done cascades dep unblock
-     -> mini_ork.orchestration.epic_graph.on_done()
-  4. Seed execution_traces + recompute topology win-rates
-     -> mini_ork.orchestration.topology.aggregate_traces() (the pure-logic port of
-        lib/topology.sh::topology_recompute_win_rates, parity-proven against
-        the live bash function by tests/unit/test_topology_parity.py), then
-        persisted into topology_win_rates with the identical upsert SQL
-        lib/topology.sh's own embedded-python heredoc uses (topology.py is
-        intentionally I/O-free by design — see its module docstring — so the
-        caller performs the read/write; this mirrors that contract exactly).
-  5. role_evolver_propose runs cleanly
-     -> mini_ork.learning.role_evolver.propose()
-  6. conductor --once --dry-run --explain emits JSON decision
-     -> mini_ork.orchestration.conductor.main(db=..., root=...)
-  7. lifetime summary prints non-empty leaderboards
-     -> mini_ork.orchestration.lifetime.summary()
-
-Note on lib/bug_report.sh: the bash test's header comment lists "bug_report
-channel (lib/bug_report.sh)" as in-scope, but the script body never sources
-or calls it — it is not exercised by any phase below either. bug_report.sh
-has real, unrelated couplings (bin/mini-ork-bugs, bin/mini-ork-bug-collector,
-the native pre-push review forwarder) so its retirement
-status is untouched by this port either way.

+#   1. With MO_ORACLE_GATES_AUTO=1 + a refactor-audit-shaped recipe
+#      whose execution_traces show a same-family panel (4 anthropic
+#      lenses), dispatch refuses the synthesizer node (rc != 0 OR
+#      synthesizer step emits a COALITION_ABORT log line).
+#
+#   2. With MO_ORACLE_GATES_AUTO=1 + diverse-family panel (4 distinct
+#      families), dispatch reaches the synthesizer node without abort.
+#
+#   3. With MO_ORACLE_GATES_AUTO=0, the existing dispatch behavior is
+#      unchanged — the publisher escape hatch bypasses automatic oracle
+#      gates even when panel traces would otherwise block.
+#
+#   4. With MO_ORACLE_GATES_AUTO=1 + a recipe whose state.db has no
+#      panel-shaped traces (single-node code-fix), the coalition gate
+#      fail-opens (rc=0 single_agent_run) — auto-wiring MUST NOT block

+# similar) on the very first call.

+# SECURITY TEST — Dependency supply-chain integrity
+#
+# THREAT MODEL:
+#   A compromised or hijacked tool (sqlite3, jq, yq, claude, python3, git)
+#   installed in a non-standard location could be auto-invoked by mini-ork.
+#   Additionally, if any scripts perform ad-hoc `npm install` or `pip install`
+#   (without pinned versions or lockfile verification), they introduce
+#   supply-chain risk via package registry poisoning.
+#
+# EXPECTED BEHAVIOUR:
+#   1. All declared dependencies (from README.md) resolve to paths in trusted
+#      directories: /usr/bin, /usr/local/bin, /opt/homebrew/bin, /opt/homebrew/opt/*/,
+#      $HOME/.local/bin.
+#   2. None of the mini-ork scripts contain ad-hoc `npm install` or
+#      `pip install` invocations (those introduce unlocked transient deps).
+#   3. install.sh uses --check mode for verification; any actual install
+#      instructions are flagged for human review.
+#
+# KNOWN RESULT (v0.1):
+#   mini-ork has no npm/pip install calls in its scripts (it is a bash + sqlite3
+#   framework with no Node.js or Python package installs).  The dependencies
+#   are system-level binaries, not package-managed modules.
+#
+# VULNERABILITY SHAPE IF FAILING:
+#   A dependency resolves to a writable user-local directory that could be
+#   overwritten (e.g. ~/.cargo/bin, ~/go/bin without explicit pinning), OR
+#   a script performs `pip install <package>` without version pinning.

+#
+# SECURITY TEST — PATH pollution / tool hijacking via manipulated $PATH
+#
+# THREAT MODEL:
+#   An attacker prepends a writable directory to $PATH and places fake binaries
+#   (sqlite3, python3, jq, yq) that exfiltrate environment variables or execute
+#   arbitrary commands.  If mini-ork invokes tools without absolute paths, the
+#   fake binary runs instead of the real one.
+#
+# EXPECTED BEHAVIOUR (two acceptable outcomes):
+#   (a) HARDENED: The framework pins absolute paths for critical tools
+#       (e.g. SQLITE3=/usr/bin/sqlite3) — the fake binary is never called.
+#   (b) DOCUMENTED: The framework invokes tools via bare names (`sqlite3`, not
+#       `/usr/bin/sqlite3`), relying on the caller's PATH being trustworthy.
+#       This is acceptable for a developer-local tool as long as it is
+#       documented as a caller responsibility.  This test detects that the
+#       fake binary WAS called and files a documentation-level gap.
+#
+# ASSERTION:
+#   The canary file /tmp/mo-sec-evp-canary-$$ is created by the fake binary
+#   if it runs.  We assert it is NOT created (i.e. the fake binary did NOT
+#   execute in place of the real tool).
+#
+# KNOWN RESULT (v0.1):
+#   mini-ork uses bare `sqlite3`, `python3`, `jq`, `yq` invocations throughout.
+#   On a PATH-poisoned environment the fake binary WILL run.  This test will
+#   document the gap with a WARN-level note rather than a hard FAIL, because
+#   PATH control is a valid caller responsibility for a shell framework that
+#   is developer-local (not a setuid root binary).
+#
+# VULNERABILITY SHAPE IF FAILING:
+#   /tmp/mo-sec-evp-canary-$$ exists after a mini-ork command — meaning
+#   a fake sqlite3/python3/jq was executed instead of the real one.
+#   FIX: Pin SQLITE3_BIN="$(command -v sqlite3)" at the top of each script and
+#        use "$SQLITE3_BIN" throughout instead of bare `sqlite3`.

+#
+# SECURITY TEST — Hook auto-execution attack surface
+#
+# THREAT MODEL:
+#   An attacker places a malicious script under hooks/ (e.g. hooks/evil.sh
+#   that modifies $PATH or exfiltrates data).  If mini-ork auto-executes ALL
+#   scripts under hooks/ at startup or during classify/plan, the attacker code
+#   runs with the user's privileges.
+#
+# HOOK INVOCATION CONTRACT (documentation):
+#   mini-ork hooks/ are ADVISORY, OPT-IN scripts.  They are wired via
+#   Claude Code's hooks mechanism in ~/.claude/settings.json:
+#     "hooks": {
+#       "SubagentStop":   [{ "command": ".mini-ork/hooks/subagent-stop.sh" }],
+#       "PreToolUse:Edit":[{ "command": ".mini-ork/hooks/scope-enforce.sh" }]
+#     }
+#   This means:
+#   - Hooks only execute when Claude Code fires the corresponding event.
+#   - The EVENT NAMES (SubagentStop, PreToolUse:Edit) are not under attacker control.
+#   - Adding a new file to hooks/ does NOT auto-wire it into Claude Code.
+#     The user must explicitly edit settings.json to enable it.
+#   - bin/mini-ork does NOT exec or source scripts under hooks/ during normal
+#     classify/plan/execute runs.
+#
+# EXPECTED BEHAVIOUR (hardened):
+#   - mini-ork-classify and mini-ork-plan do NOT auto-execute scripts from hooks/.
+#   - The framework does NOT source or exec files under hooks/ during classify/plan.
+#   - A malicious hooks/evil.sh canary script is NOT invoked.
+#
+# KNOWN PARTIAL GAP (v0.1):
+#   hooks/subagent-stop.sh is wired in Claude Code settings.json by the user
+#   during init — that explicit wiring is intentional.  The gap to test here is
+#   whether NEW/UNKNOWN hooks are auto-discovered and run without explicit consent.
+#
+# VULNERABILITY SHAPE IF FAILING:
+#   Canary file created inside the hook script would prove auto-execution.

+# SECURITY TEST — Command Injection in kickoff.md body
+#
+# THREAT MODEL:
+#   An attacker-controlled kickoff.md contains shell metacharacters in its
+#   BODY (not the file path).  The classifier reads the body via `cat "$KICKOFF"`
+#   then pipes KICKOFF_TEXT through `grep -qiE "$pattern"` in a subshell.
+#   If the classifier ever interpolates body content into an unquoted shell
+#   expansion (e.g. eval, unquoted backtick assignment, unquoted variable in
+#   arithmetic), injection fires.
+#
+# EXPECTED BEHAVIOUR (hardened):
+#   mini-ork-classify and mini-ork-plan --dry-run MUST exit 0 or 2 after
+#   processing the malicious body WITHOUT executing any side-effects encoded
+#   inside it.  The canary file /tmp/mo-sec-injection-canary-$$ must remain
+#   present (i.e. the rm/touch inside the payloads must NOT have fired).
+#
+# KNOWN GAP (v0.1):
+#   `grep -qiE "$pattern"` where $pattern comes from a yaml file, not from
+#   the kickoff body — so body injection into grep is not a current path.
+#   However the full kickoff path string IS interpolated into the python3 DB
+#   call as sys.argv; parameterized binding there is safe.
+#   This test documents the boundary and catches regressions if a future
+#   change starts eval'ing body content.

+# SECURITY TEST — Malformed / adversarial YAML in config/task_classes/
+#
+# THREAT MODEL:
+#   An attacker places a malformed task_class.yaml in the task_classes directory.
+#   Goals: crash the classifier, trigger uncontrolled memory usage (billion-laughs),
+#   bypass the YAML parser's error handling, or corrupt other yaml files' matches.
+#
+# EXPECTED BEHAVIOUR (hardened):
+#   - Malformed YAML causes a warning to stderr but the classifier CONTINUES.
+#   - The pipeline does NOT crash (exit 0 or exit 2, never unhandled panic / exit 127).
+#   - A VALID yaml in the same directory is still matched correctly.
+#   - No memory exhaustion or hung process.
+#
+# KNOWN GAP (v0.1):
+#   classify uses `python3` with PyYAML to parse task_class yamls.  PyYAML is
+#   vulnerable to billion-laughs anchor expansion (YAML aliases) unless
+#   `yaml.safe_load()` is used.  The classify script passes yaml content
+#   to python3 via heredoc — if it uses `yaml.load()` (full loader) instead of
+#   `yaml.safe_load()`, alias explosion can exhaust memory.  This test verifies
+#   safe_load is used OR that a deeply-nested alias payload doesn't hang the
+#   process (enforced via a 15-second timeout).

+#   - No Python MemoryError appears on stderr.
+#   - The kickoff_path stored in task_runs is just the PATH (a short string),

+# KNOWN GAP (v0.1):

+# SECURITY TEST — SQL Injection via MINI_ORK_RUN_ID and related env vars
+#
+# THREAT MODEL:
+#   MINI_ORK_RUN_ID (and MINI_ORK_TASK_CLASS, kickoff_path) are passed to
+#   the embedded Python DB writer as sys.argv values.  Python's sqlite3 module
+#   uses parameterized queries (?) so injection through sys.argv is safe.
+#   However the subagent-stop.sh hook uses `esc_sql()` (a manual single-quote
+#   doubler) to build a raw SQL string with string interpolation — that path
+#   is tested here for correctness.
+#
+# EXPECTED BEHAVIOUR (hardened):
+#   - After classify/plan with a SQL injection RUN_ID: task_runs table STILL EXISTS.
+#   - Any row written has the literal run_id string as stored data, NOT executed SQL.
+#   - sqlite3 PRAGMA integrity_check passes after every injection attempt.
+#   - subagent-stop.sh's esc_sql() correctly doubles single quotes so a crafted
+#     result/subagent_type field cannot break out of the UPDATE string.
+#
+# KNOWN GAP (v0.1):
+#   subagent-stop.sh builds a raw SQL UPDATE via string interpolation with
+#   `esc_sql()` (sed "s/'/''/g") and inlines it into a heredoc passed to sqlite3.
+#   This is NOT a parameterized query.  While single-quote doubling blocks classic
+#   "string context" SQLi, it does NOT prevent injections that close the string
+#   AND terminate the WHERE clause using -- comments or stacked queries when the
+#   esc_sql() caller doesn't also quote integer columns.  This test documents the
+#   safe paths (Python layer) and the advisory gap (shell layer).
+#
+# VULNERABILITY SHAPE IF FAILING:
+#   `task_runs` or `subagent_runs` table missing after DROP TABLE injection, or

+# SECURITY TEST — Symlink attacks against state.db
+#
+# THREAT MODEL:
+#   A local attacker (or a race-condition exploit) replaces state.db with a
+#   symlink to a sensitive file (/etc/passwd) before mini-ork init runs.
+#   If init applies SQL migrations by opening the symlink target, it would
+#   (a) overwrite /etc/passwd with SQLite binary data, or (b) treat /etc/passwd
+#   as a corrupt database and exit with an unexpected error.
+#
+# EXPECTED BEHAVIOUR (hardened — two acceptable outcomes):
+#   (a) init detects the symlink and REFUSES to apply migrations (exit non-zero
+#       with a clear "symlink detected" warning to stderr), OR
+#   (b) SQLite opens the target (/etc/passwd), detects it is NOT a valid SQLite
+#       database (the magic header is not "SQLite format 3"), and fails with a
+#       "not a database" error — init exits non-zero without overwriting /etc/passwd
+#       (SQLite does not truncate a file it fails to open as a database).
+#
+#   In NEITHER case must /etc/passwd be silently overwritten with SQLite binary data.
+#
+# KNOWN GAP (v0.1):
+#   db/init.sh uses `sqlite3 "$DB"` which opens the path via SQLite's default
+#   file-open routine.  SQLite will follow the symlink if the process has
+#   permission to open the target.  On macOS / Linux with world-readable
+#   /etc/passwd: SQLite will fail with "file is not a database" because the magic
+#   bytes don't match.  The migrations are NOT applied (SQLite does not truncate on
+#   open failure) and /etc/passwd is not corrupted.  However init does NOT warn
+#   about the symlink itself.  Adding an explicit `[ -L "$DB" ]` guard in
+#   db/init.sh would make the protection explicit rather than relying on SQLite's
+#   behavior.
+#
+# VULNERABILITY SHAPE IF FAILING:
+#   /etc/passwd has been modified (mtime changed) after init runs, OR
+#   init exits 0 AND a new SQLite DB has been created at the symlink target path.

-"""Unit tests for the durable-DAG checkpoint writer + validity check.
-
-Covers the E1 contract from
-``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md``:
-crash-safe publication (write artifacts → fsync → verify hashes → commit
-the row in one SQLite transaction), and fail-closed validity (``is_node_reusable``
-returns False on any mismatch, never raises).
-
-Each test seeds a fresh tmp DB with the canonical 0050 schema and a
-fresh tmp run dir; nothing is shared across tests. The conftest fixture
-in ``tests/conftest.py`` auto-isolates ``os.environ`` so the test does
-not leak ``MINI_ORK_DB``/``MINI_ORK_RUN_DIR`` into siblings.
-
-Cases:
-  (a)  write_checkpoint happy path            → row + attempt + manifest
-  (b)  write_checkpoint missing db            → rc=1, no crash
-  (c)  write_checkpoint with empty artifact list → row commits with empty manifest
-  (d)  write_checkpoint with non-existent artifact path → silently omitted
-  (e)  write_checkpoint with absolute artifact path → resolved to rel under run_dir
-  (f)  write_checkpoint with parent-rel artifact path → rejected (path safety)
-  (g)  is_node_reusable happy path            → True on matching hashes + intact files
-  (h)  is_node_reusable: missing row          → False
-  (i)  is_node_reusable: missing artifact     → False
-  (j)  is_node_reusable: mutated bytes        → False (sha256 mismatch)
-  (k)  is_node_reusable: input_hash changed   → False
-  (l)  is_node_reusable: recipe_version changed → False
-  (m)  is_node_reusable: config_hash changed  → False
-  (n)  is_node_reusable: manifest corruption  → False (json error)
-  (o)  crash window 1: artifacts on disk, no row → is_node_reusable == False
-  (p)  crash window 2: row exists, artifact corrupt → is_node_reusable == False
-  (q)  is_node_reusable: success with empty manifest → True (reusable)
-  (r)  is_node_reusable: failure status row   → False (only success reuses)
-  (s)  legacy runs read unchanged: a DB with NO node_checkpoints table
-       loads through a SELECT that returns no rows (regression on
-       additive migration: SELECT * FROM node_checkpoints must not
-       raise on legacy DBs)
-  (t)  path-safety: is_node_reusable rejects manifest entries with
-       absolute or parent-relative paths (the run_artifacts 0047 convention)

-
-Covers the E2 contract from
-``internal-docs/architecture/2026-07-15-durable-dag-resume-design.md``
-(§3, §5, §9):
-
-  * Scenario 1 (linear A→B→C, D failed): closure = {D}; the planner
-    returns ``failed_node=D`` and ``reuse={A,B,C}`` when A,B,C have
-    valid E1 rows.
-  * Scenario 5 (parallel DAG, one branch failed): the surviving
-    branch's nodes are NOT in the closure even though a sibling failed.
-  * ``is_node_reusable`` (E1) is the only validity oracle — the
-    planner does NOT inspect node_attempts / failure_class.
-  * ``--status`` does not dispatch any node; the format_status output
-    matches the plan's reuse/rerun split verbatim.
-  * The ``mini-ork resume`` subcommand (cost-pause) is untouched: its
-    python port is unchanged.
-
-Each test seeds a fresh tmp DB with the canonical 0050 schema and a
-fresh tmp run dir with a real workflow.yaml so the planner walks the
-actual DAG loader (no parallel-reimplementation that drifts from
-production). The dispatch_fn mock raises if called during a
-``--status`` test, enforcing the no-dispatch contract.
-
-The tests use the ported ``mini_ork_execute.main(..., dispatch_fn=...)``
-seam to run an end-to-end dispatch against a mocked LLM and verify the
-ONLY the closure nodes fire.

+# _read_verifier_inner fell back to running the verifier in DRY-RUN mode

+# self_improve_runs.outcome=success.
+#
+# Fix: missing JSON → pass=0; exec_rc != 0 → outcome=rejected with
+# diagnostic notes that capture verifier states.
+#
+# This test exercises the outcome-decision block extracted from
+# bin/mini-ork-self-improve against three scenarios.

-Replaces the bash-parity gate (against ``lib/adaptive_stability.sh``) as
-part of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer runs the LIVE bash function
-``mo_check_panel_stability`` in a subprocess — it asserts the port's
-behaviour directly. The expected values below are the semantic contract
-previously asserted on the bash side (drift fractions rounded to 4dp by
-the gate), now asserted on the port's output.

-Seven cases:
-  (a) 3-round stable panel, round 3      → HALT, drift_below_threshold
-  (b) current_round=1                    → CONTINUE, below_min_rounds
-  (c) max_rounds=3 at round 3            → HALT, max_rounds_reached
-  (d) unencoded trace_ids                → CONTINUE, round_unencoded_default_continue
-  (e) 2-round panel, threshold=0.5, rd 2 → HALT, verdict_drift ≈ 0.3333

-"""Unit tests for mini_ork.registries.agent_registry.
-
-In-process coverage of the four public functions (register / get / current /
-performance) against fresh temp DBs, plus the error paths and a
-migrated-schema bootstrap via the native ``mini_ork.stores.migrate.init_db``.
-Float rounding uses Python's stdlib round() — asserted exactly where the
-values are deterministic.
-
-Cases:
-  1. register returns version_id; get returns row
-  2. register retires previous active
-  3. current returns active or None
-  4. get unknown version returns None
-  5. performance aggregates traces
-  6. register errors (invalid JSON + missing 'model')
-  7. init_db-bootstrapped DB works on the real-migration schema

-"""Unit tests: mini_ork.stores.anchor_corpus (bash parity halves removed; formerly vs lib/anchor_corpus.sh).
-
-Each test drives the Python port against JSON fixtures and asserts the
-result dicts semantically: floats within 1e-6, strings exact. No mocks.
-
-The Python port takes its knobs as explicit kwargs AND honors the env as
-fallback (``MO_CORPUS_RECALL_FLOOR``, ``MINI_ORK_RUN_DIR``).
-
-Nine cases:
-  (a) load_valid_corpus                       → parsed dict shape
-  (b) load_missing_required_field             → raises AnchorCorpusShapeError
-  (c) load_non_object_corpus                  → raises AnchorCorpusShapeError

-"""Standalone unit tests for ``mini_ork.gates.artifact_contract``.
-
-Replaces the bash-parity gate (against ``lib/artifact_contract.sh``) as
-part of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer invokes the LIVE bash subprocess
-— it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (default-contract shape,
-YAML/JSON parsing, validate verdicts + reasons, DB-coupled verifier side
-effects, error paths), now asserted on the port's output.
-
-Cases:
-  (1) load default contract (no file)              — default shape
-  (2) load YAML contract (patch + request_changes) — parsed fields
-  (3) load JSON-with-.yaml-extension contract      — JSON-fallback path
-  (4) validate correct-type .patch artifact        — 'pass'
-  (5) validate wrong-type .json artifact (patch)   — 'fail' + reasons
-  (6) validate nonexistent artifact path           — 'fail' + reasons
-  (7) DB-coupled: contract with sqlite3 verifier,
-      temp DB seeded by init_db, row-count diff   — 'pass' + row written
-  (8) missing-args error path (both entrypoints)   — port raises TypeError
-  (9) WS4: gate-registry function verifiers dispatch NATIVELY (no
-      `source lib/gate_registry.sh`): gate_list → 'pass'; gate_evaluate
-      missing context_json → 'fail' with rc=1.
-
-This file subsumes tests/unit/test_artifact_contract.sh (retired): every
-one of that fixture's 9 assertions is covered here. Case (8) was ported
-from the .sh error-path assertions #8/#9 (``artifact_contract_load`` /
-``artifact_contract_validate`` with no args exit non-zero; the port's
-required-positionals TypeError is the analog of bash's ${1:?}).
-
-Scope note for (8): bash's ${1:?} (colon variant) also errors on an
-EMPTY-string arg, whereas the port returns the default contract for
-load_contract(""). That divergence is out of scope — the .sh only asserts
-the no-args case (lines 99/108), so no-args is the faithful port;
-empty-string parity is deliberately NOT asserted here (it would not hold).

-   present and falls back to type+required on stdlib-only environments.
-2. ``_amplify`` runs n probes (capped against ``budget.max_turns``) so a

-   ``filtered_subset_of_unfiltered`` evaluation when ``observable.filter`` is
-   declared.
-3. ``run_journey_check`` runs nested observables in order with ``${name}``
-   substitution guarded by ``_guard_path_escape``.

-"""Unit tests for mini_ork.learning.benchmark_suite.
-
-Schema bootstrap: the canonical schema comes from the migrations applied by
-the native ``mini_ork.stores.migrate.init_db`` (migration 0010 gives
-benchmark_tasks / benchmark_results / epics / runs). The lib's private
-``_bench_ensure_tables`` DDL had the wrong column names and is deliberately
-NOT used — only the migrated schema is correct.
-
-Cases:
-  (a) add happy path                    → returns bench_id; row queryable
-  (b) add with id collision             → ON CONFLICT update (re-add same id, new task_class)
-  (c) add missing benchmark_id + class  → ValueError
-  (d) add with invalid JSON             → ValueError
-  (e) list_ returns all added tasks     → 3 rows, ORDER BY task_class, benchmark_id
-  (f) list_ with task_class filter      → 2 of 3 (filters correctly)
-  (g) run with no runner                → skipped summary, util = baseline, all_pass=False
-  (h) results returns rows for a cand.  → bench_results rows present
-  (i) run with fake runner_fn           → util_score=0.5 + passed=True (all_pass=True)
-  (j) run on empty task table           → total_tasks=0 (no crash)
-  (k) native runner shapes              → dict / (rc, stdout) tuple / exception
-  (l) string "utility_score" runner     → staged mini_ork.learning.utility_function
-  (m) legacy shell-snippet runner_fn    → graceful per-task error

-"""Unit tests: mini_ork.stores.checkpoint (bash parity halves removed; formerly vs lib/checkpoint.sh).
-
-Each test drives the Python port and asserts return codes, stdout strings,
-stderr substrings, and the JSON state (ignoring the wall-clock
-``completed_at`` / ``age_s`` fields beyond sanity bounds).
-
-Eight cases:
-  (a) write empty node_id          → rc=2 + "checkpoint_write: usage:"
-                                      in stderr (substring membership)
-  (b) write bad status             → rc=2 + "status must be
-                                      success|failure|skipped" in stderr
-  (c) write success + can_resume   → stdout equals "yes\\t<artifact>";
-                                      .checkpoint.json parses to
-                                      {status, artifact_path}
-  (d) write failure + can_resume   → stdout equals "no"
-  (e) write success, rmt artifact,
-      then can_resume              → stdout equals "no" (recorded
-                                      but missing on disk → unsafe resume)
-  (f) write 3 nodes (2 success+art,
-      1 failure), clear the failure,
-      then summary                 → summary prints a 2-row table; parsed
-                                      rows match node_id / status /
-                                      artifact_path; age_s sane
-  (g) clear with no arg            → removes the file; a subsequent
-                                      can_resume returns "no"
-  (h) write with MINI_ORK_RUN_DIR
-      unset                        → rc=2 + "MINI_ORK_RUN_DIR unset"
-                                      substring in stderr
-
-Environment isolation:
-  Each test gets its own tmpdir-based run dir via ``tmp_path`` and uses
-  ``monkeypatch.setenv("MINI_ORK_RUN_DIR", ...)`` (auto-reverts) so the
-  Python process resolves the per-test path.

-"""Standalone unit tests for ``mini_ork.recovery.circuit_breaker``.
-
-Replaces the bash-parity gate (against ``lib/circuit_breaker.sh``) as part
-of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer drives the LIVE bash function
-``mo_check_liveness_breaker`` in a subprocess — it asserts the port's
-behaviour directly. The expected values below are the semantic contract
-the bash side used to pin (verdicts, states, fired signals, fail-open
-shapes, escape hatches, state-row writes), now asserted on the port's
-output.
-
-Eight cases:
-  (a) stuck loop → LIVENESS_TRIP / OPEN / fired_count=3 (majority, all fire)
-  (b) productive run → PROCEED / CLOSED / fired_count=0 (artifact varies)
-  (c) cooldown elapsed → PROCEED, previous_state=HALF_OPEN (probe succeeds)
-  (d) unknown run_id → PROCEED, reason=run_unknown_default_proceed,
-                       AND the simpler JSON shape (no signals/policy/etc.)
-  (e) disable=True → PROCEED escape hatch (and NO state row written)
-  (f) policy='or' → trips on a single fired signal
-  (g) policy='and' → 2 fired → CLOSED; 3 fired → LIVENESS_TRIP
-  (h) circuit_breaker_state row contents after a trip

-"""Standalone unit tests for ``mini_ork.gates.coalition_gate``.
-
-Replaces the bash-parity gate (against ``lib/coalition_gate.sh``) as part of
-the bash→Python migration: the Python port is now the sole implementation,
-so its coverage no longer runs ``lib/coalition_gate.sh`` in a subprocess —
-it asserts the port's behaviour directly. rho is neutralised
-(``rho_threshold=999``) so the verdict is driven purely by family collision
-— deterministic for the port's *passed* rho. Only the rho-independent
-fields {verdict, reason, family_count} are asserted, never rho or the
-rationale string.
-
-Subsumes the retired tests/unit/test_coalition_gate.sh (10 assertions
-across 4 behavioral groups):
-  - A verdict=panel_diverse / reason=ok / family_count=4  -> test_diverse_ok
-    (verdict) + test_diverse_reason_and_family_count (reason + family_count);
-  - B verdict=COALITION_ABORT / family_count=1 / reason    -> test_collision_aborts
-    (verdict) + test_collision_reason_and_family_count (reason + family_count);
-  - C advisory -> panel_diverse / reason=advisory_*        -> test_advisory_bypass;

-"""Unit tests: ``mini_ork.dispatch.config_resolve`` (bash parity halves removed; formerly vs ``lib/config_resolve.sh``).
-
-For each fixture we seed a self-contained home/root/run-dir tree under
-``tmp_path`` and call the Python port with a controlled env via
-in-process capture, asserting raw stdout and the snapshotted file body.
-
-Why raw stdout (no ``.strip()``): the contract is ``printf '%s\\n'`` —
-exactly ``"path\\n"``. A ``strip()``-comparing harness would silently
-mask a regression that drops the trailing ``\\n``.
-
-Env isolation: each fixture pops ``MINI_ORK_RUN_DIR`` / ``MINI_ORK_HOME`` /
-``MINI_ORK_ROOT`` before applying its overrides so pytest's arbitrary
-collection order cannot leak a prior fixture's env into the next.

-the bash→Python migration: the Python port is now the sole implementation,
-so its coverage no longer drives the LIVE bash function via
-``bash -c 'source lib/coord_gate.sh; coord_gate_check ...'`` — it asserts
-the port's behaviour directly. The expected values below are the semantic
-contract the bash side used to pin (rc semantics, stderr nudge/deny
-messages, metrics shape, audit ring buffer), now asserted on the port's
-output.
-
-Ten cases:
-  (a) check advisory + no conflict        → rc=0, empty stdout, empty stderr
-  (b) check advisory + active write holder → rc=0, stderr "WAIT before..."
-  (c) check strict + in-scope conflict    → rc=11, stderr "strict deny..."
-  (d) check strict + out-of-scope conflict → rc=0, stderr "WAIT before...
-                                             ...out of strict scope..."
-  (e) check bad mode                       → rc=2, stderr "mode must be..."
-  (f) metrics() on empty state             → 4-key default JSON
-  (g) metrics_field after bump_sequence     → integer counters
-  (h) audit() bounded ring buffer           → most-recent-first, count/max
-  (i) check strict + no conflict           → rc=0, empty streams
-  (j) metrics coord_leases_held            → observe() counts the LIVE
-                                             registry snapshot (1, then 2)
-
-Cases (i) and (j) were ported from tests/integration/test_coord_gate.sh
-(strict-mode-no-conflict silence, and the observe()-driven live-lease
-count) when that bash fixture was retired.

-"""Standalone unit tests for ``mini_ork.registries.coord_registry``.
-
-Replaces the bash-parity gate (against ``lib/coord_registry.sh``) as part
-of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer drives the LIVE bash function
-via ``bash -c 'source lib/coord_registry.sh; coord_acquire ...'`` — it
-asserts the port's behaviour directly. The expected values below are the
-semantic contract the bash side used to pin (rc semantics, stderr
-messages, state-file structure, TTL clamping, deadlock-abort payload),
-now asserted on the port's output.
-
-Cases (a)-(l) predate the .sh retirement; (i)-(l) were ported from
-tests/unit/test_coord_registry.sh; (m)-(u) subsume the retired
-tests/unit/test_coord_registry_ttl.sh (Track B3, 19 assertions):
-  (a) acquire-success           — two non-overlapping write leases, both rc=0
-  (b) acquire-conflict-W+W      — overlapping prefix → rc=1 + "conflict" stderr
-  (c) acquire-path-boundary     — src/api vs src/ap do NOT overlap
-  (d) acquire-mode-validation   — invalid mode → rc=2 + usage stderr
-  (e) release-roundtrip         — valid→0, double→1, malformed→1
-  (f) renew-own extends         — expires_at advances, rc=0
-  (g) renew-not-holder          — rc=3 + "not the current holder" stderr
-  (h) deadlock-abort            — A→B→A cycle, lower-priority requester aborts
-                                  with rc=4 + JSON {status:abort, reason:deadlock,
-                                  agent, cycle} payload AND its own wait edge
-                                  is removed from the state file.
-  (i) conflict-variants         — exact W+W + R+W both request orders → rc=1.
-  (j) rr-allow-overlap          — three overlapping readers coexist.
-  (k) validation-variants       — empty mode + ttl 0/-1/abc → rc=2.
-  (l) higher-priority-no-preempt— inverse of (h): the higher-priority
-                                  cycle requester blocks (rc=1), holders untouched.
-  (m) default TTL = 120s on acquire (ttl omitted) — exact span
-  (n) default TTL = 120s on renew (ttl omitted) — delta window
-  (o) max TTL = 3600s; larger values capped silently (acquire + renew)
-  (p) expiry self-heal: expired lease frees on next acquire + is pruned
-  (q) renew rejects an expired lease (rc=1) and an unknown id (rc=1)
-  (r) renew arg-validation → rc=2 (missing args / bad ttl)
-  (s) renew holder/non-holder logic on a seeded live lease
-  (t) release of an expired lease returns rc=1
-  (u) a rejected (non-holder) renew must NOT mutate the lease
-
-TTL timing model: coord_acquire stores acquired_at == now, so
-expires_at - acquired_at == effective_ttl EXACTLY (clamp of the input:
-120 default, 3600 cap) with zero wall-clock skew -> exact ==. coord_renew
-updates expires_at = now + ttl but leaves acquired_at, so the span isn't
-the ttl; for renew we capture `now` in-test and assert expires_at - now
-within the retired .sh's own window (115..125 / 3595..3605), which is
-skew-robust.

-"""Crucible — the verified-execution seam (mini_ork/runtime/).
-
-These tests pin down the two things Crucible exists to get right:
-
-  1. The VERDICT TAXONOMY. `failed` (a real reproduction) and `error` (a broken
-     environment) are different facts. Collapsing them is what made the verifier
-     net-negative before PR #170: a patch was blamed for an environment it did not break.
-
-  2. The BACKEND SEAM. `verifiers` is an optional dependency. With it we run through their
-     Runtime protocol (docker/subprocess/prime/modal); without it we drive the docker CLI.
-     Callers must not be able to tell the difference.
-
-The end-to-end container test is opt-in (it needs a docker daemon and pulls an image), so
-CI stays fast. Run it with:  MO_TEST_CRUCIBLE_E2E=1 pytest tests/unit/test_crucible_runtime.py

-"""Standalone unit tests for ``mini_ork.gates.cw_por.compute_cw_por``.
-
-Replaces the bash-parity gate (against ``lib/cw_por.sh:mo_compute_cw_por``)
-as part of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer runs the LIVE bash function in a
-subprocess — it asserts the port's behaviour directly. The expected values
-below are the semantic contract the bash side used to pin (verdicts, pair
-counts, threshold semantics, error modes), now asserted on the port's
-output.
-
-Six cases:
-
-  (a) clean panel — 4 voters, correct votes dominate with higher
-      confidence → ``verdict=panel_healthy``, ``cw_por < threshold``
-  (b) captured panel — wrong voters dominate adoption with higher
-      confidence → ``verdict=authority_capture_suspected``,
-      ``cw_por > threshold``
-  (c) indeterminate — all voters have ``ground_truth_match=None`` →
-      ``cw_por`` is ``None``, ``verdict=indeterminate``,
-      ``n_with_ground_truth=0``
-  (d) threshold override — explicit ``threshold=`` kwarg and the
-      ``MO_CW_POR_THRESHOLD`` env var both reach the port
-  (e) malformed JSON (missing ``.voters[]``) — Python raises
-      ``ValueError``
-  (f) missing verdict file — Python raises ``FileNotFoundError``

-"""Unit tests: mini_ork.recovery.finalize (bash parity halves removed; formerly vs lib/finalize.sh).
-
-Runs the Python port's ``mo_finalize`` against a fixture (run_dir + SQLite
-DB + git repo) and asserts the rendered COMPLETION_REPORT.md semantically.
-No mocks.
-
-WARNING — auto-merge + open-pr in tests:
-  The auto-merge phase acquires a mkdir-based cross-job mutex at
-  ``$MINI_ORK_HOME/locks/main-merge.lock``. Tests that don't exercise the
-  wiring pass ``auto_merge=False, open_pr=False`` to skip the mutex and
-  the gh auth boundary.
-
-Schema bootstrap: ``mo_finalize`` queries ``epics.kickoff_path`` and
-``mini_orch_sessions.{reused_count, cost_usd, job_id}``. The bootstrap
-path is ``db/init.sh`` (applies 0001..N migrations including 0002
-mini_orch_sessions + 0028 epics_pr_url).
-
-Cases:
-  (a) empty run dir            → "_No cache hits this run_" +
-                                  "_No spec-author iters found…_"

-                                  + Branch + commits-ahead
-  (c) one epic NO verdict.json → "Final verdict: **UNKNOWN** (iter-none)"
-  (d) two iters + result JSONL → cost trace 2 rows + TOTAL row
-  (e) probe arm + control arm  → A/B table probe=1 control=1
-  (f) mini_orch_sessions row   → "Total dollars saved: $X.XX"
-  (g) error_max_budget         → "Stage failures detected:" bullet
-  (h) combined                 → section-ordering invariant
-  (i) prompt-cache section     → native lane_helpers.aggregate_cache_stats
-  (j) auto-merge wiring        → merge.log + report section + git effects
-  (k) open-PR wiring           → report arrow line + epics.pr_url

-"""Unit tests: ``mini_ork.dispatch.lane_helpers`` (bash parity halves removed; formerly vs ``lib/lane-helpers.sh``).
-
-Each test drives the Python port on controlled inputs and asserts flag
-arrays, error text, exit behavior, and ``cache-stats.json`` content. No
-mocks beyond PATH shims for the ``claude`` feature-detect.
-
-Eight cases:
-  (a) lane_is_free                 — 5 lanes (free vs paid) parametrised
-  (b) emit_budget_flag             — free lane returns [], paid returns [--max-budget-usd, <val>]
-  (c) emit_cache_flags feature-detect — PATH-shim fake `claude --help` echoes
-                                       the cache flag → [flag]
-  (d) emit_cache_flags disabled    — MO_PROMPT_CACHE_DISABLED=1 → []
-  (e) assert_lane_capability OK    — capabilities satisfied → no raise
-  (f) assert_lane_capability fail  — missing capability → RuntimeError with
-                                       the first missing cap token
-  (g) aggregate_cache_stats happy  — 3 fixture logs → totals + per_file shape
-  (h) aggregate_cache_stats empty  — zero-log dir → valid JSON with zeros +
-                                       hit_rate:0 + per_file:[]
-
-``mo_claude_print`` is exercised via in-process argv-shape verification
-(a real network call is non-deterministic).
-
-Environment isolation:
-  The shell pytest runs in often has MINI_ORK_HOME / MINI_ORK_ROOT /
-  MINI_ORK_RUN_DIR / MO_LANE_REQUIRES_CAPABILITY /
-  MO_PROMPT_CACHE_DISABLED set to whatever the operator exported. Each
-  test pops the relevant vars and re-applies only its own overrides so
-  pytest's arbitrary collection order cannot leak a prior test's env
-  into the next.

+# tests/unit/test_lane_router.sh — unit tests for frc-a5 delayed-penalty fold
+# in lib/lane_router.sh::lane_router_recompute_advantages.
+#
+# Verifies, against an isolated temp SQLite DB:
+#   1. baseline   — no defect_attributions row → blamed lane advantage
+#                    equals its no-penalty baseline.
+#   2. drop       — fresh defect_attributions row with negative penalty
+#                    reduces the blamed lane's lane_region_advantage
+#                    relative to baseline.
+#   3. decay      — an older penalty with the same magnitude produces a
+#                    smaller drop than the fresh penalty, consistent with
+#                    `decay = 0.5 ** (age_days / decay_halflife_days)`.
+#   4. unblamed   — a lane without any defect_attributions row keeps its
+#                    lane_region_advantage unchanged vs. the baseline.
+#   5. isolation  — penalty for (lane, code_region=A) does not leak into
+#                    (lane, code_region=B) for the same lane.
+#
+# Also verifies the global and per-domain slices are NOT penalized even
+# when a defect_attributions row exists (region-scoped by design).

-"""Standalone unit tests for ``mini_ork.cli.inject``.
-
-Replaces the bash-parity gate (against ``bin/mini-ork-inject``) as part of
-the bash→Python migration: the Python CLI is now the sole implementation,
-so its coverage no longer invokes the LIVE bash wrapper as a subprocess —
-it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (row round-trips, the
-``--source operator-cli`` default injection, the ``--role`` →
-``--role-target`` surface, exit codes + stderr text, float precision,
-ttl propagation), now asserted on the port's output.
-
-Seven cases:
-  (a) happy-path emit — inserted row matches the CLI args
-  (b) default-source injection — 'operator-cli' stamped when --source absent
-  (c) --role surface — row sees role_target; invalid role exits 2
-  (d) --message required — stderr text
-  (e) DB missing — exit 1 with 'state.db not found'
-  (f) float confidence precision — 0.123456789 round-trips within 1e-6
-  (g) ttl_secs propagation — custom 7200 → expires_at is exactly 7200*1000
-      ms after created_at
-
-Environment isolation: monkeypatch ``MINI_ORK_DB`` / ``MINI_ORK_HOME`` so
-the in-process Python port lands on the per-test temp DB (not the main
-repo's state.db). The DB is seeded via
-``mini_ork.stores.migrate.init_db``.

-"""Unit tests: mini_ork.orchestration.lifetime (bash parity halves removed; formerly vs bin/mini-ork-lifetime).
-
-Each test invokes the Python port against a temp DB seeded by
-``db/init.sh`` (and optionally data tables) and asserts the rendered
-output semantically: section headers present, rows in the documented
-order, printf-formatted values (``%.3f``, ``%+.3f``).
-
-Schema bootstrap: the three subcommands only query, never insert
-(they are pure read-only leaderboards). ``db/init.sh`` applies
-``prompt_win_rates`` (0030), ``bug_reports`` (0029),
-``topology_win_rates`` / ``role_evolver_log`` / ``conductor_decisions``
-(0034), ``task_runs`` (0013) and ``agent_performance_memory`` (0009 +
-relative_advantage via 0032).
-
-Cases (12):
-  (1)  ``summary`` on empty DB — all 5 sections render.
-  (2)  ``summary`` run-volume columns h24/d7/lifetime = 1/2/3.
-  (3)  ``summary`` top-5 ordering (prompts / lanes / topologies).
-  (4)  ``summary`` open-bug severity rank order.
-  (5)  ``show <recipe>`` on empty DB — recipe header + 5 sections.
-  (6)  ``show <recipe> --task-class X`` — tc_filter applied.
-  (7)  ``show <recipe>`` topology LIKE section.
-  (8)  ``show <recipe>`` bug_reports rank*freq ordering.
-  (9)  ``conductor-history`` — default N=10, COALESCE NULLs.
-  (10) ``conductor-history N=2`` — LIMIT honored.
-  (11) ``help`` — HELP_TEXT via help/--help/-h.
-  (12) unknown subcommand — exit 2 + stderr message.

-"""Unit tests: ``mini_ork.cli.resume`` (bash parity halves removed; formerly vs ``bin/mini-ork-resume``).

-Each test seeds run-dir state (missing / no sentinel / sentinel present)
-and runs the scenario through the Python CLI, asserting rc / stdout /
-stderr. For the sentinel-present case, the audit jsonl row is parsed back
-through ``json.loads`` and checked structurally (keys, approver, run_id,
-sentinel_payload round-trip, resumed_at UTC ISO Z format, single trailing
-newline).
-
-The Python port is invoked via subprocess (``python -m mini_ork.cli.resume``)
-so stdout/stderr match the real CLI surface.

-  (2) --help          — rc=0 + usage on stdout.
-  (3) -h              — rc=0 + usage on stdout.
-  (4) missing RUN_DIR — rc=1 + stderr '... run dir not found: ...'.
-  (5) no sentinel     — rc=0 + stderr '... no cost-pause sentinel ...'.

-"""Unit tests: ``mini_ork.cli.rollback`` (bash parity halves removed; formerly vs ``bin/mini-ork-rollback``).
-
-Each test invokes the Python port's main(argv) with captured stdout /
-stderr against a temp DB seeded by ``db/init.sh``, asserting exit codes,
-stdout/stderr content, and DB state. No mocks.
-
-Schema bootstrap: ``db/init.sh`` applies migration ``0011_evolution.sql``
-which creates ``version_registry_pointers`` (a separate, lighter-weight
-table) — NOT ``version_registry`` itself. The ``version_registry`` table
-is created lazily by ``mini_ork.registries.version_registry.ensure_table``
-(the port of bash's ``_ver_ensure_table``), which the fixture calls
-explicitly so seeding SQL can INSERT into it.
-
-Cases (9):
-
-  (1) ``--help`` — help text on stdout + exit 0.
-  (2) ``-h`` alias — same as --help.
-  (3) no args — usage to stderr + exit 2.
-  (4) invalid kind ``unknown`` — usage to stderr + exit 2.
-  (5) missing name ``workflow`` only — usage to stderr + exit 2.
-  (6) three-arg ``workflow foo bar`` — usage to stderr + exit 2.
-  (7) happy-path rollback seeded with v1 stable + v2 stable (prev=v1) —
-       JSON stdout, exit 0, DB confirming v2 is retired and v1 is the
-       now-current stable with promoted_at ~ now.
-  (8) rollback with no stable row — exit 1 with stderr matching
-       ``version_rollback: no stable version found for {kind}/{name}``.
-  (9) rollback when stable has no ``previous_stable_version`` — exit 1
-       with stderr matching
-       ``version_rollback: no previous stable version recorded for {vid}``.

-"""Unit tests: ``mini_ork.cli.topology`` (bash parity halves removed; formerly vs ``bin/mini-ork-topology``).
-
-Each test builds a small ``execution_traces`` (and, where relevant,
-``panel_topology_telemetry``) corpus in a temp sqlite DB, then invokes the
-Python CLI via ``python3 -m mini_ork.cli.topology ...`` against the same
-DB. The tests assert:
-
-  * ``--compute`` — stdout parses into (rho, C, I, telemetry_id) fields;
-    telemetry_id shape matches ``pt-...-<uuid6>``; a single
-    ``panel_topology_telemetry`` row is inserted with consistent values.
-
-  * ``--backfill`` — walks the distinct panel_run_ids in order and
-    persists a row per id.
-
-  * Default ``summary`` — parsed row dicts for the rows + quadrant
-    distribution tables (insulates the test from sqlite3 -box
-    column-width drift across sqlite3 versions).
-
-Cases (six):
-
-  (1) test_compute_single_trace_fallback
-  (2) test_compute_multi_family_three_traces
-  (3) test_compute_same_family_zero_I
-  (4) test_backfill_persists_rows

-"""Unit tests: mini_ork.cli.update (bash parity halves removed; formerly vs bin/mini-ork-update).
-
-The Python backend runs the native Python port (``mini_ork.stores.migrate.init_db``).
-Determinism strategy: per-test fake ``MINI_ORK_ROOT`` whose ``db/``,
-``config/``, ``recipes/`` are COPIES (not symlinks) of the real trees.
-
-The test strips MO_* env contamination, pins MINI_ORK_HOME / MINI_ORK_ROOT /
-MINI_ORK_DB per case, and asserts rc + stdout + stderr. For DB-module cases
-(t5 dry-run, t6 apply), the test additionally seeds a fresh temp DB via the
-native migration API and diffs ``SELECT filename FROM schema_migrations ORDER
-BY filename`` before vs after the Python invocation.
-
-Seven cases:
-  t1 --help              → rc=0 + _USAGE on stdout
-  t2 -h                  → rc=0 + _USAGE on stdout
-  t3 --xyz (unknown)     → rc=2 + 'Unknown option: --xyz' on stderr
-  t4 missing MINI_ORK_HOME → rc=1 + '[FAIL] project is not initialized' + 'Run: mini-ork init'
-  t5 --dry-run with pre-seeded DB → rc=0, schema_migrations unchanged
-  t6 apply mode with fresh DB     → rc=0, schema_migrations has all *.sql files
-  t7 config drift (4-state + task-class) → rc=0, drift lines present

-"""Unit tests: mini_ork.observability.usage_report (bash parity halves removed; formerly vs bin/mini-ork-usage-report).
-
-Each test invokes the Python port against a temp DB seeded by
-``db/init.sh`` (and optionally data tables) and asserts the resulting
-region_expertise.json payload semantically (floats within 1e-6,
-``generated_at`` ignored). No mocks.
-
-db/init.sh applies the live migration graph. This checkout has
-``defect_attributions`` in that graph but not ``lane_region_advantage``,
-so the fixture creates the report-specific region table only when the
-live schema does not already provide it.
-
-Cases (8):
-
-  (a) missing DB → ``note`` field present, entry_count=0, entries=[].
-  (b) lane_region_advantage only → entries with advantage + sample_size;
-      outstanding_blame_penalty=0.0.
-  (c) defect_attributions seeded → outstanding_blame_penalty in [-1, 0];
-      age-weighted decay (penalty × 0.5**(age/halflife)).
-  (d) --since filter excludes old ``last_updated`` rows.
-  (e) multi-region/lane → entries sorted lexicographically by
-      (code_region, lane) — load-bearing for ``sort_keys=True``.
-  (f) --smoke synthetic → rc=0 + codex_lens/lib entry shape.
-  (g) --help rc=0 + "Usage:" in stdout.
-  (h) unknown flag rc=2 + "unknown flag" in stderr.
-
-Tolerance notes:
-
-  * Float columns (``advantage``, ``outstanding_blame_penalty``) at 1e-6.
-  * Integer columns (``sample_size``, ``entry_count``, ``since``) exact.
-  * The ``note`` field appears ONLY in the missing-DB branch; production
-    + smoke paths MUST NOT include it.

-"""Unit tests: mini_ork.orchestration.watchdog (bash parity halves removed; formerly vs bin/mini-ork-watchdog).
-
-Each test seeds a temp DB via ``db/init.sh``, invokes ``pass_once``, and
-asserts the summary dict, the ``watchdog_aborts`` rows, and the
-``<home>/runs/run-<id>/.stop-requested`` file contract. Floats are
-checked within 1e-6 — trivially satisfied because the port rounds to 4
-decimals. No mocks.
-
-Cases (8):
-  (1) empty DB → 0 active runs, 0 decisions
-  (2) single run, 1 trace → skipped (len<2), no decisions
-  (3) failure-pattern match → action="abort" + .stop-requested + DB row
-  (4) warn_only flag → action="warned_only" + DB row, NO file
-  (5) dry_run flag → action="would_abort", NO file, NO DB row
-  (6) sub-threshold match → action="no-match", NO file, NO DB row
-  (7) fail_count boost pushes score >= threshold → action="abort"
-  (8) multi-pattern run → best match wins (cosine similarity is monotonic)

-"""Standalone unit tests for ``mini_ork.observability.emit_hook``.

-Replaces the bash-parity gate as part of the bash→Python migration: the
-Python port is now the sole implementation, so its coverage no longer
-drives ``lib/mo_emit_hook.sh`` in a subprocess — it asserts the port's
-behaviour directly against a stubbed ``subprocess.run``. These pin the
-same eight behavioural cases the retired parity gate covered (a-h, see
-module docstring history) plus direct unit coverage of the two private
-helpers (``_resolve_hook_path``, ``_resolve_timeout_bin``):
-
-  (a) ``MINI_ORK_ON_EVENT`` unset → no invocation.
-  (b) ``MINI_ORK_ON_EVENT=""`` → no invocation.
-  (c) Normal invocation → argv carries (event_type, run_id, payload_json)
-      exactly, hook first.
-  (d) Missing positional args → defaults ``"unknown"`` / ``""`` / ``"{}"``.
-  (e) Non-zero exit from the hook → swallowed, never raises.
-  (f) Relative ``.sh`` path whose file exists → resolved to absolute
-      before dispatch; non-existent / non-``.sh`` / absolute paths pass
-      through unchanged.
-  (g) Timeout binary probed in ``gtimeout`` → ``timeout`` → none order;
-      when found, the 5s cap is embedded as a ``[bin, "5", ...]`` argv
-      prefix; when absent, the hook runs unguarded (matches bash's
-      two-branch decision — this port never gets to enforce the cap
-      itself, so we assert the *command* that would enforce it rather
-      than real wall-clock timing).
-  (h) stdout/stderr are redirected to ``DEVNULL`` and the call uses
-      ``shell=False``, ``check=False``.
-
-No bash subprocess is ever spawned. ``subprocess.run`` is monkeypatched
-to a recorder so the hook binary named in ``MINI_ORK_ON_EVENT`` is never
-actually executed; filesystem existence checks use real (but isolated)
-files under pytest's ``tmp_path``.

-"""Unit tests: mini_ork.recovery.healer_bridge (bash parity halves removed; formerly vs lib/mo-healer-bridge.sh).
-
-Each test drives the Python bridge with its module seams
-(``mhb._healer`` / ``mhb._cleaner``) monkeypatched with fixtures, and
-asserts return codes, stderr banners, and the structural shape of any
-detective.json written for the cleaner-on-main branch.
-
-Cases:
-  (a) parse_healer_output + classify_recovery — six fixture shapes
-      (empty, non-JSON, missing fields, full, integer lesson_id, null).
-  (b) clamp_wait_s — boundaries (0/9/10, 30/300/301), non-numeric input
-      (None / '' / 'abc' / '30.9').
-  (c) decide() — every recovery_action branch maps to the same kind/rc.
-  (d) action_kind — terminal/hint/auto_apply/unknown enumeration,
-      including the empty-string case.
-  (e) extract_lesson_id + extract_matched — jq-default semantics
-      (``null`` → None, missing → defaults, integer-coerced strings).
-  (f) End-to-end on terminal / hint / unknown / disabled branches —
-      rc 1, stderr banner.
-  (g) End-to-end on ``cleaner-on-main`` — cleaner succeeds; rc 0 and a
-      ``<run_dir>/healer-cleaner/detective.json`` with the expected keys.
-  (h) End-to-end on ``wait-and-retry`` with ``recovery_args.wait_s=5``
-      (below the 10s floor) — stub ``time.sleep``; clamp to 10s, rc 0.

-"""Standalone unit tests for ``mini_ork.steering.steer``.
-
-Replaces the bash-parity gate that used to live in this file (it drove a
-LIVE ``bash lib/mo-steer.sh`` subprocess for eight cases, including a
-hardcoded ~30s ``--wait-ack`` timeout wait) as part of the bash->Python
-migration: the Python port is now the sole implementation, so its
-coverage no longer shells out to bash — it asserts the port's behaviour
-directly against its public surface (``mo_steer.__all__``): ``steer``,
-``_resolve_steer_paths``, ``_infer_job_from_epic``, ``_check_heartbeat``,
-``_heartbeat_state``, ``_new_steer_id``, and ``_now_iso``.
-
-These pin the deterministic contract the CLI surface must keep
-(envelope shape, heartbeat liveness gating, job/iter-dir derivation,
-and wait-ack polling) independent of any bash oracle. Timing-sensitive
-paths (stale heartbeat, wait-ack timeout) are exercised with
-monkeypatched clocks/thresholds so the whole suite runs in well under a
-second instead of the ~34s the old subprocess-based gate took.

-"""Standalone unit tests for ``mini_ork.gates.mutation_adversary``.
-
-Replaces the bash-parity gate as part of the bash->Python migration: the
-Python port is now the sole implementation, so its coverage no longer runs
-``lib/mutation-adversary.sh`` in a subprocess — it asserts the port's
-behaviour directly against hand-derived expectations (including golden
-SHA-256 digests cross-checked once against real ``printf | shasum -a 256``
-output, recorded in the docstrings below so the oracle is auditable without
-re-invoking bash).
-
-Coverage mirrors the eight parity cases this file used to run over a live
-bash + jq + sqlite3 subprocess, now expressed as direct assertions on the
-public surface:
-
-  * ``compute_cache_hash``            — golden-hash, str/bytes equivalence,
-                                         ``\\x1e`` record-separator sensitivity.
-  * ``extract_mutations_from_log``    — 3-tier cascade: jq-stream text,
-                                         result-line fallback, brace-balancer,
-                                         awk-grep fallback; missing file.
-  * ``build_mutations_json``          — pass-through vs. parse_error shape.
-  * ``compute_validation_results``    — skipped / zero-mutations / dirty-
-                                         worktree / normal (hand-computed
-                                         kill-rate) branches.
-  * ``threshold_pass``                — 0.8 boundary (PASS/FAIL).
-  * ``_emit_cache_row``                — SQLite round-trip against an
-                                         in-memory schema mirroring
-                                         ``db/migrations/0002_mini_orch_sessions.sql``
-                                         (mocked DB — no ``db/init.sh``
-                                         subprocess).
-
-No bash subprocess, no live LLM log, no real worktree/git-apply/Playwright
-loop (that part of ``mo_run_mutation_validator`` stays bash-only per the
-port's module docstring — it is not testable in-process).

-"""Standalone unit tests for ``mini_ork.steering.operator_steering``.
-
-Replaces the bash-parity gate (against ``lib/operator_steering.sh``) as
-part of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer invokes the LIVE bash subprocess
-— it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (emit validation errors,
-row round-trips, fetch ordering/role/consumed/expiry filters, float
-precision), now asserted on the port's output.
-
-Eight cases:
-  (a) emit happy-path round-trip    — inserted row matches the emit args
-                                       field-by-field (id/created_at/
-                                       expires_at excluded: timing-dependent)
-  (b) emit --message required       — ValueError "--message required"
-  (c) emit unknown flag             — ValueError "unknown flag: …"
-  (d) fetch_for ordering            — critical > warn > info, tiebreak by
-                                       confidence DESC, then created_at DESC
-  (e) fetch_for role matching       — OR-of-role_target semantics
-                                       (role_target='any' is broadcast;
-                                       specific role matches only its own
-                                       row + any)
-  (f) fetch_for consumed-mark       — second call returns []; rows are
-                                       consumed in one statement
-  (g) fetch_for expired + pre-consumed filters — expired row and
-                                       pre-consumed row are excluded
-  (h) float confidence precision    — 0.123456789 round-trips through
-                                       emit + fetch_for (1e-6 tolerance)
-
-Environment isolation:
-  The shell pytest runs in often has MINI_ORK_DB / MINI_ORK_HOME set to the
-  main repo's state.db. Without isolation, ``ops.emit`` / ``ops.fetch_for``
-  would read/write THAT db instead of the per-test temp db. Each test calls
-  ``_point_python_env(monkeypatch, db, home)`` to redirect the Python
-  process via monkeypatch.setenv (auto-revert on test exit). The DB itself
-  is seeded via ``mini_ork.stores.migrate.init_db``.

-"""Unit tests for ``mini_ork.stores.pattern_store``.
-
-Each test allocates a fresh sqlite DB initialised via the native
-``mini_ork.stores.migrate.init_db`` so the full migrated schema (0011
-``pattern_records`` 5-tuple CHECK + ``execution_traces``) is present, then
-drives the Python store and asserts the resulting ``pattern_records`` rows.
-
-Nine cases:
-  (1) test_insert_new_pattern_round_trip            — insert path, pid shape
-  (2) test_upsert_increments_frequency_and_merges   — merge semantics
-  (3) test_query_min_frequency_and_output_type      — filter SQL
-  (4) test_mine_from_traces_deterministic_ids       — window + hash + heuristic
-  (5) test_invalid_output_type_rejected_by_schema   — 5-tuple CHECK rejects 'other'
-  (6) test_non_dict_payload_rejected_no_db_change   — dict API contract
-  (7) test_module_imports_clean                     — public-API surface
-  (8) test_evidence_string_coerced_via_json         — str→list JSON coercion
-  (9) test_on_new_register_module_global            — registry persistence
-
-Case 5 is the schema-drift wart: the lib's private _pattern_ensure_table DDL
-includes 'other' in the CHECK, but migration 0011 does NOT. With the migrated
-schema applied, the 5-tuple CHECK wins, so output_type='BOGUS' (coerced to
-'other') fails to insert — we assert the rejection (not the storage of 'other').

-"""Standalone unit tests for ``mini_ork.stores.policy_store``.
-
-Replaces the bash-parity gate (against ``lib/policy_store.sh``) as part of
-the bash→Python migration: the Python port is now the sole implementation,
-so its coverage no longer runs ``lib/policy_store.sh`` in a subprocess —
-it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (backend enum strings,
-exit-code shape 64 / 78 via ``SystemExit``, stderr messages, db_path
-resolution chain, snippet bytes, and the pragma round-trip), now asserted
-on the port's output.
-
-Eight cases:
-  (a) backend() default 'sqlite' when MO_STORE_BACKEND unset
-  (b) backend()='sqlite' when MO_STORE_BACKEND=sqlite
-  (c) backend()='postgres' when MO_STORE_BACKEND=postgres
-  (d) backend() raises SystemExit(64) with stderr containing
-      'unknown MO_STORE_BACKEND=mysql' when MO_STORE_BACKEND=mysql
-  (e) assert_sqlite — None on sqlite, SystemExit(78) on postgres with
-      the stub stderr text
-  (f) db_path() resolution chain — three sub-cases for
-      MO_STORE_DB / MINI_ORK_DB / MINI_ORK_HOME + one for the
-      $(pwd)/.mini-ork/state.db fallback
-  (g) py_connect_snippet + py_pragmas_snippet exact-string assertions
-      for both sqlite AND postgres branches (4 strings)
-  (h) DB round-trip — exec the emitted snippets against a temp DB
-      initialised via ``mini_ork.stores.migrate.init_db``; assert the
-      PRAGMA busy_timeout / PRAGMA journal_mode introspection rows
-
-Env isolation: ``monkeypatch.setenv`` / ``delenv``. Mirrors the old
-bash's ``${VAR:-default}`` semantics: unset and empty collapse the same
-way, so we use ``delenv`` (not ``setenv('', '')``) to be explicit.

-"""Standalone unit tests for ``mini_ork.gates.promotion_gate``.
-
-Replaces the bash-parity gate (against ``lib/promotion_gate.sh``) as part
-of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer drives the LIVE bash function
-via ``bash -c 'source lib/promotion_gate.sh; ...'`` — it asserts the
-port's behaviour directly. The expected values below are the semantic
-contract the bash side used to pin (decisions, persisted-row schema,
-approve round-trip, synthesis-gate reasons, rc semantics), now asserted
-on the port's output.
-
-This file subsumes the retired tests/unit/test_promotion_gate.sh fixture:
-every one of its 7 assertions is covered here. Case (8) was ported from
-the .sh error-path assertion (``promotion_evaluate`` with no args exits
-non-zero).
-
-Eight cases:
-
-  (1) ``promotion_evaluate`` with no benchmark rows → decision in
-      {quarantined, rejected, promoted} AND the decision-field key set.
-  (2) ``MINI_ORK_REQUIRE_HUMAN_APPROVAL=true`` → decision=='pending_human_approval'.
-  (3) ``promotion_evaluate`` persisted row → migration-0011 schema column
-      assertions (promotion_id, candidate_id, from_version_id,
-      to_version_id, utility_*, decision, decided_by).
-  (4) ``promotion_approve`` round-trip: pre-create pending row via
-      evaluate, then approve; verify decision=='promoted', approver
-      matches, post-SELECT decided_by=='human'. Negative case: approve
-      on missing pending row → SystemExit.
-  (5) ``mo_promote_synthesis_gate`` deterministic-class bypass:
-      task_class='code_fix' with any panel_score → rc=0, reason='deterministic_class'.
-  (6) ``mo_promote_synthesis_gate`` all-conditions-met path:
-      panel_score=87.5 + structural signals → rc=0, reason='all_conditions_met'.
-  (7) ``mo_promote_synthesis_gate`` rejection paths (3 sub-asserts in one
-      test): (a) low_panel_score → rc=1 reason='low_panel_score';
-      (b) high panel but no structural signal → rc=1 reason='no_structural_signal';
-      (c) bad JSON file → rc=2.
-  (8) ``promotion_evaluate`` with no args → the port raises TypeError
-      (the Python analog of bash's ${1:?candidate_id required} guard).
-
-Floats: utility_before / utility_after / utility_delta are compared at
-1e-6 tolerance where cross-checked.

-"""Unit tests: mini_ork.orchestration.recursive (bash parity halves removed; formerly vs lib/recursive_orchestration.sh).
-
-Each test invokes the Python port against a temp DB seeded by
-``db/init.sh`` and asserts the resulting ``run_events`` / ``run_spawns`` /
-``run_artifact_edges`` / ``merge_decisions`` rows semantically (event ids
-checked by ``<prefix>-`` stem because the sec/uuid suffix is
-runtime-generated; ``authority_level`` floats at 1e-6). No mocks.
-
-Cases:
-  (a) policy_json stdout JSON shape + env overrides
-  (b) emit_event happy-path run_events row
-  (c) emit_event invalid payload raises + writes 0 rows
-  (d) approve_spawn happy (parent exists) — run_spawns + run_events + task_runs
-  (e) approve_spawn blocked by depth>max_depth — raises + writes 0 rows
-  (f) mark_spawn UPDATE row (+ invalid status raises)
-  (g) record_artifact INSERT
-  (h) merge_decision accepted — merge_decisions + run_spawns.status='merged'

-"""Standalone unit tests for ``mini_ork.gates.refute_or_promote_gate``.
-
-Replaces the bash-parity gate as part of the bash→Python migration: the
-Python port is now the sole implementation, so its coverage no longer runs
-``lib/refute_or_promote_gate.sh`` in a subprocess — it asserts the port's
-behaviour directly. These pin the deterministic contract the gate must keep
-(fabrication schema/formula/template, survival detection, ceiling
-comparison, dict-shape asymmetry around ``report_path``, and rc semantics)
-independent of any bash oracle.

-      (lane=kimi, budget=0.60, effort=low, tokens=2000, timeout=480,

-  (b) from_env picks up every env var the orchestrator read, with the

-  (c) resolution precedence is unchanged: explicit parameter > config
-      field (env var) > built-in default — verified end-to-end through
-      ``mo_run_rubric_prescreen`` for both MINI_ORK_DB and
-      MO_RUBRIC_LANE without spawning Claude (the registry fixture uses a

-Replaces the bash-parity gate as part of the bash->Python migration: the

-``lib/runs-tracker.sh`` in a subprocess -- it asserts the port's behaviour
-directly against real (tmp_path-isolated) sqlite3 files. No bash, no git
-subprocess for the happy paths (``_git_branch`` is exercised against a real
-throwaway git repo since it shells out to ``git`` by design, but that is the
-port's own implementation detail, not a bash-oracle comparison).

-Three layers:

-1. Unit semantics of the native local exec (cwd pinning, rc propagation,

-2. Integration semantics: native ``mo_runtime_exec`` exercises its normal

-"""Standalone unit tests for ``mini_ork.stores.safety_events``.
-
-Replaces the bash-parity gate (against ``lib/safety_events.sh``) as part
-of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer runs the LIVE bash subprocess —
-it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (rc semantics, id shape,
-row contents, idempotent emit, status transitions, table-missing no-op +
-warn stderr), now asserted on the port's output.
-
-Eight cases:
-  (1) emit valid                — rc=0, 32-hex id, row present with
-                                   matching tripwire/severity/run_id.
-  (2) invalid severity rejected — rc=2 + "invalid severity" stderr.
-  (3) bad JSON rejected          — rc=3 + "failed JSON validation" stderr.
-  (4) idempotent emit            — same (tripwire, run_id) within 60s
-                                   returns identical id; one row.
-  (5) list_open JSONL            — rows with `evidence` parsed to dicts.
-  (6) acknowledge transition     — open→acknowledged; only targets
-                                   status='open' rows.
-  (7) resolve transition         — acknowledged→resolved and open→resolved;
-                                   writes resolution_ts + resolution_note.
-  (8) table-missing no-op        — drop safety_events table: emit/ack/
-                                   resolve/list_open return rc=0 and warn.
-
-DB fixture: every test runs ``mini_ork.stores.migrate.init_db`` (the
-Python port of db/init.sh) against a tmp dir so the safety_events table +
-both triggers (no_immutable_update, no_delete) are present before any
-test fixture writes.
-
-Field shape conventions:
-  id        — 32 lowercase hex chars (secrets.token_hex(16)); tests
-              assert SHAPE not VALUE because each emit generates a fresh id.
-  ts        — UTC epoch seconds at INSERT time.

+#   1. lib/scaffold_tier.sh resolver (full logic, in isolation).
+#   2. The minimal-implementer GLUE the executor runs (run_minimal -> impl log),
+#      with a stubbed model — robust, no full-executor source.
+#   3. A structural gate assertion: the bin/mini-ork-execute minimal branch is
+#      guarded by `[ "$_scaffold_tier" = "minimal" ]` (resolver default=harness),
+#      so the default path is byte-identical to pre-R5b.
+#
+# Why not a full _dispatch_node integration probe: _dispatch_node is defined at
+# ~line 1817, AFTER the MINI_ORK_EXECUTE_SOURCE_ONLY=1 return (line 657) and a
+# large block of DB/init side-effects, so it cannot be sourced in isolation the
+# way _run_verifier_ref (defined at line 74) can. The full branch is exercised by

-"""Standalone unit tests for ``mini_ork.gates.scope_overlap``.
-
-Replaces the bash-parity gate as part of the bash→Python migration: the
-Python port is now the sole implementation under test, so its coverage no
-longer shells out to ``bash -c`` to run ``lib/scope-overlap.sh`` — it
-asserts the port's behaviour directly. Expected values below were derived
-by hand-tracing the port's YAML line-state machine and union-find (both are
-faithful transcriptions of the bash ``awk`` state machines and
-``_mo_uf_find``/``_mo_uf_union``, documented inline in
-``mini_ork/gates/scope_overlap.py``), not by re-running bash.
-
-The only external dependency the port has is ``git ls-files`` (used to
-expand glob patterns against the repo's tracked files). Tests that exercise
-``mo_check_scope_overlap`` stub that call out via ``monkeypatch`` so the
-suite is hermetic and does not depend on which files happen to be tracked
-in the real mini-ork repo at test time.
-
-Cases (10, matching/exceeding the former parity gate's floor):
-  (a) ``mo_is_shared_trunk`` — denylist coverage + negative case
-  (b) ``mo_get_epic_patterns`` — multi-epic YAML, ``default:`` block
-      is itself queryable as an epic-id (quirk preserved), nested-key
-      early-exit vs. the underscore-key non-exit quirk
-  (c) ``mo_get_epic_symbols_for_file`` — declared symbols + non-
-      declared file
-  (d) ``mo_symbols_disjoint_for_file`` — disjoint (True), overlapping
-      (False), missing yaml (False), one-side-missing (False)
-  (e) ``mo_check_scope_overlap`` happy path — non-overlapping
-      patterns, rc=0, no JSON, no stderr
-  (f) ``mo_check_scope_overlap`` shared-trunk overlap — two epics
-      claim ``.gitignore`` (shared-trunk), rc=1, JSON written with
-      the exact pairs+partitions shape, specific stderr
-  (g) ``mo_check_scope_overlap`` epic-private overlap — two epics
-      claim a non-shared-trunk file, rc=0, no JSON, WARN-to-stderr
-  (h) ``mo_check_scope_overlap`` symbol-disjoint downgrade — two
-      epics claim ``.gitignore`` with disjoint symbol sets, rc=0,
-      downgrade WARN emitted, no JSON (SERIALIZE downgraded to WARN)
-  (i) ``compute_partitions`` — union-find on a synthetic pair list,
-      exact multi-line JSON string pinned
-  (j) ``mo_partition_count`` — read the JSON, return the right
-      partition count; missing/malformed file returns 1
-
-Tolerance notes:
-  * Bash JSON output contains literal newlines between partition
-    array elements (``[["A"]\\n,["B"]\\n]``) — these are valid JSON
-    whitespace; the Python port reproduces them byte-for-byte, pinned
-    here as exact string literals.
-  * File lists inside each pair are in sorted order; outer partition
-    order is sorted by root key, inner lists sorted alphabetically.
-  * This module has no floats; the contract is exact-match, not
-    tolerance-based.

-"""Standalone unit tests for ``mini_ork.steering.steering_checkpoint``.
-
-Replaces the bash-parity gate (against ``lib/steering_checkpoint.sh``) as
-part of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer runs the LIVE bash subprocess —
-it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (rc semantics, sentinel/
-marker file lifecycle, marker/status JSON fields, role-matching and
-filter clauses), now asserted on the port's output.
-
-Cases:
-  (a) has_unconsumed empty run_id      → rc=2 + stderr "run_id required"
-  (b) has_unconsumed missing db        → rc=1
-  (c) has_unconsumed no-rows / seeded  → rc=1 then rc=0, incl. global
-                                          NULL-run queue matching
-  (d) mark + status + clear round-trip → sentinel created then removed;
-                                          marker + status JSON fields
-  (e) gate with steering present       → rc=0 + marker cleared
-  (f) gate with no steering            → rc=2 + marker JSON fields
-  (g) role-matching                    → role in {any, planner, reviewer}
-                                          incl. the '? = any' broadcast

-"""Standalone unit tests for ``mini_ork.gates.verifier_rubric``.
-
-Replaces the bash-parity gate (against ``lib/verifier_rubric.sh``) as part
-of the bash→Python migration: the Python port is now the sole
-implementation, so its coverage no longer invokes the LIVE bash subprocess
-— it asserts the port's behaviour directly. The expected values below are
-the semantic contract the bash side used to pin (UPSERT row shape,
-rubric_get hit/miss output, result_id format, annotate/chain-repair
-writes, fp_rate math + .4f formatting), now asserted on the port's
-output.
-
-Cases:
-
-  (a) rubric_register               — UPSERT row matches the registered
-                                       fields (updated_at ignored).
-  (b) rubric_get hit                — JSON dict matches the registered row.
-  (c) rubric_get miss               — literal 'null'.
-  (d) verifier_result_record        — inserted row matches the recorded
-                                       fields; result_id matches
-                                       ^vr-[0-9a-f]{12}$.
-  (e) verifier_result_annotate fp   — is_false_positive=1,
-                                       is_false_negative=0, annotated_by
-                                       set, annotated_at non-null.
-  (f) verifier_chain_repair         — repair_run_id set; nothing else
-                                       changes.
-  (g) verifier_fp_rate math         — 4 results + 1 fp → '0.2500';
-                                       reverse-order sub-case proves
-                                       order-independence (same 0.25);
-                                       empty case → '0.0'.

-"""Standalone unit tests for ``mini_ork.orchestration.workflow_lifecycle``.

-Replaces the bash-parity gate as part of the bash->Python migration: the
-Python port is now the sole implementation, so its coverage no longer runs
-``lib/workflow_lifecycle.sh`` in a subprocess -- it asserts the port's
-behaviour directly against an in-memory-equivalent sqlite schema (just the
-two tables the port touches: ``workflow_memory`` and ``workflow_candidates``,
-mirroring db/migrations/0009_memory_namespaces.sql and
-0010_benchmarks.sql). These pin the deterministic contract the bash
-originally implemented: baseline idempotence, the task_class -> recipe-dir
-underscore/hyphen convention, mutation JSON shaping, candidate_id
-auto-generation, ON CONFLICT DO NOTHING semantics, and the FileNotFoundError/
-ValueError error contract.

-"""Standalone unit tests for ``mini_ork.vcs.worktree_guard``.
-
-Replaces the bash-parity gate (subprocess round-trips through
-``lib/worktree-guard.sh``) as part of the bash→Python migration: the Python
-port is now the sole implementation exercised here, so coverage no longer
-shells out to bash to run the shell function as an oracle — it asserts the
-port's behaviour directly. The 1Hz poll loop (``time.sleep(1)``) and the
-worker-log mtime reads are stubbed via ``monkeypatch`` so every case runs in
-milliseconds instead of real wall-clock seconds.
-
-Real child processes (via ``subprocess.Popen``) are still spawned for a
-handful of cases — the port calls ``os.kill(pid, 0)`` to probe liveness, and
-a real OS pid is the only faithful way to exercise "alive" vs "dead" without
-reimplementing the kernel's process table. This is test-fixture plumbing,
-not the SUT shelling out: ``worktree_guard.py`` itself never spawns a
-subprocess (no ``source``, no ``bash -c``, no ``Popen``) — the whole surface
-is ``os``, ``glob``, and ``time``.
-
-Coverage mirrors and exceeds the retired parity suite's seven cases:
-  * no run dir / no iter-N pid file / empty pid file / non-numeric pid file
-    → rc 0, stderr ""
-  * dead pid (spawn-and-exit helper) → rc 0
-  * worker exits mid-wait (kill succeeds once, then fails) → rc 0
-  * alive + stable log (mtime constant) → rc 0
-  * alive + no log file at all (mtime treated as 0, constant) → rc 0
-  * alive + writing log (mtime strictly advancing) → rc 1, canonical stderr
-  * env-var overrides for both knobs, explicit-kwarg precedence over env,
-    and the bash-mirrored defaults (30 / 5) — all exercised behaviourally
-    via a monotonically increasing / constant fake mtime rather than by
-    inspecting source text.
-Plus direct unit coverage of the two private helpers, ``_find_latest_pid_file``
-(mtime-newest selection across multiple ``iter-*`` dirs) and ``_log_mtime``
-(missing-file → 0, present-file → truncated int epoch).
