From 852f76e697c71398a0c23538cca3b861899c2866 Mon Sep 17 00:00:00 2001 From: James Dunnam <7660553+jimador@users.noreply.github.com> Date: Thu, 11 Jun 2026 14:05:42 -0400 Subject: [PATCH 01/22] feat(projection): graph projection observability, lineage, and edge authority Makes projection to a graph observable and traceable, and carries source authority through to the projected edges. - GraphProjectionService and RelationBasedGraphProjector report why a projection was skipped or failed instead of failing silently; Projection carries structured failure reasons - ProjectionRecord lineage records what projected where; ProjectionLineageStaleCascade cascades a stale mark to everything a stale proposition projected - ProjectionPolicySupport carries a proposition's source authority onto the projected edge Signed-off-by: James Dunnam <7660553+jimador@users.noreply.github.com> --- .../graph/GraphProjectionService.kt | 100 +++++++++++-- .../dice/projection/graph/GraphProjector.kt | 44 +++--- .../projection/graph/LlmGraphProjector.kt | 24 ++-- ...ataRepositoryGraphRelationshipPersister.kt | 58 ++++++-- .../graph/ProjectionPolicySupport.kt | 37 +++++ .../graph/RelationBasedGraphProjector.kt | 107 +++++++++----- .../lineage/InMemoryProjectionRecordStore.kt | 30 +++- .../lineage/ProjectionLineageStaleCascade.kt | 54 ++++++++ .../lineage/ProjectionRecordStore.kt | 35 ++++- .../embabel/dice/proposition/Projection.kt | 113 ++++++++++++--- .../graph/EdgeAuthorityProjectionTest.kt | 125 +++++++++++++++++ .../GraphProjectionServiceLineageTest.kt | 131 ++++++++++++++++++ ...raphProjectionServiceReconciliationTest.kt | 122 ++++++++++++++++ ...epositoryGraphRelationshipPersisterTest.kt | 72 ++++++++++ .../graph/RelationBasedGraphProjectorTest.kt | 130 +++++++++++++++++ .../InMemoryProjectionRecordStoreTest.kt | 63 +++++++-- .../ProjectionLineageStaleCascadeTest.kt | 99 +++++++++++++ .../lineage/ProjectionRecordTest.kt | 8 +- .../lineage/ProjectionRecordTraceTest.kt | 74 ++++++++++ 19 files changed, 1293 insertions(+), 133 deletions(-) create mode 100644 dice/src/main/kotlin/com/embabel/dice/projection/graph/ProjectionPolicySupport.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/projection/lineage/ProjectionLineageStaleCascade.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/graph/EdgeAuthorityProjectionTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/graph/GraphProjectionServiceLineageTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/graph/GraphProjectionServiceReconciliationTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/lineage/ProjectionLineageStaleCascadeTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/lineage/ProjectionRecordTraceTest.kt diff --git a/dice/src/main/kotlin/com/embabel/dice/projection/graph/GraphProjectionService.kt b/dice/src/main/kotlin/com/embabel/dice/projection/graph/GraphProjectionService.kt index c0fd5602..155fc3ed 100644 --- a/dice/src/main/kotlin/com/embabel/dice/projection/graph/GraphProjectionService.kt +++ b/dice/src/main/kotlin/com/embabel/dice/projection/graph/GraphProjectionService.kt @@ -16,40 +16,118 @@ package com.embabel.dice.projection.graph import com.embabel.agent.core.DataDictionary +import com.embabel.dice.projection.lineage.ReconciliationDecision +import com.embabel.dice.projection.lineage.Reconciler +import com.embabel.dice.projection.lineage.AlwaysCreateReconciler +import com.embabel.dice.projection.lineage.ProjectionLifecycle +import com.embabel.dice.projection.lineage.ProjectionRecord +import com.embabel.dice.projection.lineage.ProjectionRecordStore +import com.embabel.dice.proposition.ProjectionFailed import com.embabel.dice.proposition.ProjectionResults +import com.embabel.dice.proposition.ProjectionSkipped +import com.embabel.dice.proposition.ProjectionSuccess import com.embabel.dice.proposition.Proposition +import java.util.UUID /** - * Facade that bundles a [GraphProjector], [GraphRelationshipPersister], and [DataDictionary] - * to simplify the common project-and-persist workflow. + * Bundles a [GraphProjector], [GraphRelationshipPersister], and [DataDictionary] together + * so you can project propositions to graph relationships and persist them in one call. * - * @param graphProjector The projector to use for converting propositions to relationships - * @param persister The persister to use for storing projected relationships - * @param schema The data dictionary for relationship validation + * @param graphProjector converts propositions to relationships + * @param persister writes those relationships to the graph + * @param schema data dictionary used for relationship validation + * @param recordStore optional lineage store; when supplied, one [ProjectionRecord] is + * written per result (PROJECTED / ADOPTED / SKIPPED / FAILED).

charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the projection-lineage SPI to a real repository, adds a reference Neo4j adapter, and gives DICE one front door for getting source material in. - RepositoryBackedReconciler resolves whether to create or reuse a graph artifact by looking it up, instead of always creating — what keeps re-projection from duplicating nodes; comes with a seeded-graph integration proof - Neo4jRagPropositionRepository is a reference store backed by the RAG entity store, declaring only the capability fragments it honestly supports - ingestion SPI: IngestionHandler / TextIngestionHandler turn artifacts into chunks; IngestionLedger dedups by content hash; IngestionResult reports per batch - Testcontainers test-scope deps and a Docker Engine api.version pin for the proof Signed-off-by: James Dunnam <7660553+jimador@users.noreply.github.com> --- dice/pom.xml | 23 ++ .../dice/ingestion/IngestedArtifact.kt | 116 +++++++++ .../embabel/dice/ingestion/IngestionBatch.kt | 41 ++++ .../dice/ingestion/IngestionHandler.kt | 60 +++++ .../embabel/dice/ingestion/IngestionLedger.kt | 95 ++++++++ .../embabel/dice/ingestion/IngestionResult.kt | 81 +++++++ .../ingestion/support/TextIngestionHandler.kt | 100 ++++++++ .../lineage/RepositoryBackedReconciler.kt | 54 +++++ .../store/Neo4jRagPropositionRepository.kt | 122 ++++++++++ .../dice/eval/CanonicalFlowFixtures.kt | 135 +++++++++++ .../dice/eval/FixedPropositionExtractor.kt | 67 ++++++ .../dice/eval/FixedVectorEmbeddingService.kt | 56 +++++ .../InMemoryGraphRelationshipPersister.kt | 70 ++++++ .../dice/ingestion/IngestionHandlerSpiTest.kt | 92 +++++++ .../ingestion/IngestionLedgerDedupE2ETest.kt | 153 ++++++++++++ .../ingestion/TextIngestionHandlerTest.kt | 225 ++++++++++++++++++ .../graph/SeededGraphNoDuplicateNodesIT.kt | 209 ++++++++++++++++ .../lineage/RepositoryBackedReconcilerTest.kt | 122 ++++++++++ .../Neo4jRagPropositionRepositoryTest.kt | 198 +++++++++++++++ .../store/RagAdapterDeclaredFragmentsIT.kt | 179 ++++++++++++++ 20 files changed, 2198 insertions(+) create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/IngestedArtifact.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/IngestionBatch.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/IngestionHandler.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/IngestionLedger.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/IngestionResult.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/ingestion/support/TextIngestionHandler.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/projection/lineage/RepositoryBackedReconciler.kt create mode 100644 dice/src/main/kotlin/com/embabel/dice/proposition/store/Neo4jRagPropositionRepository.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/eval/CanonicalFlowFixtures.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/eval/FixedPropositionExtractor.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/eval/FixedVectorEmbeddingService.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/eval/InMemoryGraphRelationshipPersister.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/ingestion/IngestionHandlerSpiTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/ingestion/IngestionLedgerDedupE2ETest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/ingestion/TextIngestionHandlerTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/graph/SeededGraphNoDuplicateNodesIT.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/projection/lineage/RepositoryBackedReconcilerTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/proposition/store/Neo4jRagPropositionRepositoryTest.kt create mode 100644 dice/src/test/kotlin/com/embabel/dice/proposition/store/RagAdapterDeclaredFragmentsIT.kt diff --git a/dice/pom.xml b/dice/pom.xml index ef5fe9d7..15dae7a4 100644 --- a/dice/pom.xml +++ b/dice/pom.xml @@ -111,6 +111,29 @@ test + + + org.testcontainers + neo4j + test + + + + org.testcontainers + junit-jupiter + test + + + + org.neo4j.driver + neo4j-java-driver + test + + diff --git a/dice/src/main/kotlin/com/embabel/dice/ingestion/IngestedArtifact.kt b/dice/src/main/kotlin/com/embabel/dice/ingestion/IngestedArtifact.kt new file mode 100644 index 00000000..b8df7ba7 --- /dev/null +++ b/dice/src/main/kotlin/com/embabel/dice/ingestion/IngestedArtifact.kt @@ -0,0 +1,116 @@ +/* + * Copyright 2024-2026 Embabel Pty Ltd. + * + * Licensed under the Apache License, Version 2.0 (the "License");

feat(storage): durable Neo4j projection and collector record stores DICE shipped only in-memory ProjectionRecordStore and CollectorRecordStore. Add Drivine-backed implementations that persist projection lineage and the collector audit trail as graph nodes, so they survive a restart and stay queryable. The graph-backed projection store also implements a real markStaleByProposition (the SPI default is a no-op), keeping the lifecycle cascade working against a durable store. Both are wired through DiceStorageAutoConfiguration on the existing embabel.dice.store.type=graph flip, default to in-memory otherwise, and are ConditionalOnMissingBean so an application's own bean wins. Reads and writes use parameterized Cypher (MERGE on the natural key for idempotent upserts); row mapping is extracted so it can be unit-tested without a database.

This note is about the decisions that keep the projected graph honest — not +about the projector classes themselves. + +## Edge lineage + +When a proposition becomes a graph edge, that's not the end of the story — DICE writes a record of +it. Each projection result becomes a `ProjectionRecord` (which proposition, which target, which +graph artifact, the outcome, and when), and the projected edge itself carries the IDs of the source +propositions and the authority tier of their source. + +The reason is auditability. An edge with no provenance is an opaque assertion: you can't ask "where +did this come from?" or "how much should I trust it?" Keeping the record turns the graph into +something you can interrogate. The record store is even reversible — given a node in the graph you +can find every record that created or adopted it — so a graph artifact can always be traced back to +the text that justified it. + +Authority travels with the edge for the same reason it matters everywhere else (see +[proposition-lifecycle](proposition-lifecycle.md)): a relationship derived from a first-party record +shouldn't be weighed the same as one inferred from a passing mention. The tier is re-stamped +whenever an edge is re-persisted, so it's never silently lost. + +## Projection outcomes + +Projection isn't a boolean. A proposition might be successfully projected as a new edge, *adopted* +onto a node that already existed, *skipped* because it met no projection criteria, or *failed* +because something threw. DICE records which of these happened for every proposition, with a reason +for the skips and failures. + +The point is that these outcomes mean different things to whatever decides what to re-project later. +"Nothing to do here" and "this broke" look identical if you only track success/failure, and you'd +either retry things that were fine or ignore things that need attention. Distinguishing *adopted* +from *newly projected* also records the reconciliation decision in the lineage, not just in the +graph write. + +```mermaid +flowchart TD + P[Proposition] --> RECON{"Reconcile against

Second, the cascade only marks the *records* stale; it +doesn't rip out the actual edge. Edge removal or refresh is a re-projection concern, and keeping the +cascade to a fast, idempotent "flag it" step means a status change never triggers expensive graph +surgery inline. The stale flag is a signal to downstream consumers that the edge needs a refresh, +not the refresh itself. + +The trigger is the `PropositionStatusChanged` event (see [events](events.md)) — this cascade is the +one place DICE consumes its own events, so nothing has to remember to run it: + +```mermaid +sequenceDiagram + autonumber + participant Life as A proposition's status changes + participant Bus as Event bus + participant Cascade as Stale-cascade listener + participant Records as Projection records + Life->>Bus: status becomes superseded / contradicted / stale + Bus->>Cascade: deliver the change + Cascade->>Records: mark every record derived from this proposition stale + Note over Records: the graph edge is left intact — the mark is only a refresh signal for later +``` + +## Idempotent ingestion and reconciliation + +Re-running ingestion or re-projecting a source should be safe and cheap. DICE guards both ends. + +At the **front door**, content is dedup'd by hash before any extraction runs. Extraction is an LLM +call; doing it twice on identical content wastes money and mints duplicate propositions. The ledger +claims a content hash atomically so two concurrent ingests of the same artifact can't both proceed — +and if extraction fails, the claim is released so a transient error doesn't permanently block +re-ingestion. (A second, durable layer tracks processed chunks across sessions for the incremental +path.) + +At the **graph end**, a reconciler checks the live graph before creating anything: if an entity a +proposition mentions already exists, the projection adopts that node instead of minting a duplicate. +The default match is exact-ID and deterministic — the reconciler would rather create a clean new +node than guess a fuzzy match and merge two things that aren't the same. + +The unifying idea is that ingestion and projection are operations you'll run repeatedly over +overlapping material, so they're built to converge rather than accumulate. + +## Backend access through a port + +The durable backend is Neo4j, but the core never depends on it directly — it depends on SPIs. +Proposition storage sits behind the `PropositionStore` interface, lineage and other records behind +their own store interfaces, and the entity/relationship axis behind embabel-agent's entity-repository +port. All the Neo4j-specific wiring lives in the storage module; domain code never imports a graph +driver. Because the core talks only to those interfaces, you can swap the backend or test against an +in-memory substitute. + +One consequence worth noting: the entity-repository-backed proposition store deliberately declares +only what it can honestly support — plain storage and vector search — and not proposition-scoped +graph traversal or temporal queries, because the entity-scoped repository can't genuinely back them. +That's the same "declare only what you really support" stance the store layer takes. + +## Configurable behavior + +The reconciler, the projection record store, and the authority resolver are all pluggable.

The decisions worth explaining are +the ones around *how* retrieval stays honest across different backends, why trust filtering happens +when you read rather than when you write, how the system surfaces connections nobody queried for, +and why it can explain itself. This note is about those choices. + +## Store-agnostic graph queries + +Neighborhood, path, and lineage queries don't require a graph database. A proposition that mentions +two resolved entities already *is* an edge between them, so the portable query surface answers +graph-shaped questions by walking propositions one hop at a time over whatever store is underneath. +A native graph backend gets routed to first when it can do the traversal faster, but the portable +walk is always there as the floor. + +The decision behind this is that graph-shaped *reasoning* shouldn't be chained to graph +*infrastructure*. A lightweight in-memory setup should still answer "how is A connected to B?" +without standing up Neo4j. And when a capability genuinely isn't there, these operations return +empty or null rather than throwing — asking a question the backend can't fully answer gives you +"nothing found," not an error. + +## Query-time authority filtering + +Graph queries take an optional authority floor. Edges below it are dropped *during* the traversal, +with authority re-resolved from each proposition's provenance as the walk proceeds — nothing is +filtered out at write time. + +This is a deliberate tradeoff. Trust policy changes more often than data does, and different callers +want different floors over the same facts. Baking a trust cutoff into stored edges would mean +re-ingesting everything whenever the policy moved, and would force one global standard on every +consumer. Filtering at read time keeps the stored graph complete and lets each query decide how +cautious to be. The safe-fail detail matters here: a proposition with no provenance resolves to the +weakest tier, so any non-trivial floor drops it — unknown provenance is treated as low trust, not +waved through. + +## Single retrieval entry point + +There are several ways to find propositions — by vector similarity, by entity, by walking the graph, +by time window, or a hybrid that blends similarity with graph neighborhood. Rather than make callers +know which of these the backing store can do and how to combine them, DICE puts a single router in +front of all of them. + +```mermaid +flowchart LR + Q[DiscoveryQuery] --> R{Retrieval router} + R -->|VECTOR| V[similarity] + R -->|ENTITY| E[by entity] + R -->|GRAPH_WALK| G[neighborhood] + R -->|TEMPORAL| T[time window] + R -->|HYBRID| H[vector ∪ graph, merged] + V --> DTO[Result: mode + supported + DTOs] + E --> DTO + G --> DTO + T --> DTO + H --> DTO +``` + +The router checks whether the backing store actually supports a mode and, if not, returns an empty +result that *says so* (`supported = false`) rather than silently falling back to a full scan. It also +clamps result size and traversal depth before doing any work. The reason for one entry point is that +the caller — a REST client, an agent tool, internal code — shouldn't have to reason about the store's +capabilities; that's exactly the knowledge the router is there to hold. + +## DTO boundary and context isolation + +Everything that crosses out to a caller is a DTO of primitives and enums — never an internal type +like a proposition or a store handle. And the request itself never carries a context of its own: the +agent tools fix the context when they're constructed, and the REST layer takes it from the URL path. + +Two concerns drive this. One is a stable external contract: internal types can evolve without +breaking the wire, and a leak-check guards against a domain type sneaking into a DTO by accident. The +other is isolation — because the request body has no context field, a caller *cannot* ask one +context's endpoint for another context's data. Cross-context reads aren't forbidden by a check; +they're structurally impossible, and an LLM given the agent tools can't wander across context +boundaries either. + +```mermaid +sequenceDiagram + autonumber + participant Caller as REST client or agent tool + participant Entry as Discovery entry point + participant Router as Retrieval router + participant Store + Note over Entry: the request carries no context of its own —

But some of the most +valuable knowledge is the connection you didn't know to look for. DICE surfaces these: it scans a set +of propositions, builds the co-mention graph, and reports pairs of entities that are never mentioned +together yet are both linked to a shared third entity. + +```mermaid +flowchart LR + A[Entity A] --- X[Entity X] + X --- B[Entity B] + A -. never co-mentioned .- B +``` + +The design decision is that this is *proactive* rather than reactive — anchorless discovery instead of +anchored lookup. It's kept purely structural and deterministic (two hops over co-mention edges, over +active propositions only), which makes it cheap and reproducible. And it deliberately reports only +evidence quality, not a "surprise" ranking — the confidence on a discovered link reflects how well +the evidence supports it, and judging which links are *interesting* is left to the consumer. Each +discovered link starts as a candidate and carries a review state, because suggesting a connection and +accepting it as known are different acts. + +## Explainability: rationale and reports + +DICE can produce a rationale for a proposition — an explanation of *why* it's held, citing the +evidence behind it — and a structured report that aggregates a set of propositions by status, level, +and confidence. The rationale is interpretive, so it's generated by a language model behind an +interface that isolates that dependency (and treats the proposition text it embeds as untrusted +input, since it originally came from ingested documents). The structured report is the opposite: pure, +deterministic aggregation with no model in the loop, so it's reproducible and safe to build on. + +The reason both exist is that a knowledge system you can interrogate is one you can trust.

callers never branch on backend"] + M --> SAME +``` + +The point is that the rest of DICE is written against the SPIs and never learns which backend won. +The graph backend even declares only the capabilities it can genuinely honour (vector search, graph +traversal, temporal queries); a leaner backend simply doesn't claim them, and callers degrade rather +than break — the same "declare only what you really support" stance the store layer takes everywhere. + +## Dedup as defense in depth + +Concurrent chunk extraction is the normal case, and two chunks can independently mint the *same* +fact — identical `(contextId, text)`. Letting both land would inflate confidence and double-count +evidence, so the durable backend guards against it in two layers rather than trusting either alone. + +The first layer is an application-level **stripe-locked find-then-insert**: a `save()` takes a lock +keyed on the content, checks for an existing node, and reuses it instead of inserting a twin. That +catches the common case cheaply within one instance. The second layer is a Neo4j **uniqueness +constraint** on `(contextId, text)` — a database-enforced backstop for the case the application lock +can't see, two writers in *different* JVMs racing the same fact. When that constraint fires, `save()` +catches the violation and falls back to reusing the existing node. + +```mermaid +flowchart TB + S["save(proposition)"] --> L["stripe lock on (contextId, text)"] + L --> F{"node already exists?"} + F -->|yes| REUSE["reuse it — no twin minted"] + F -->|no| INS["insert"] + INS --> C{"uniqueness constraint
(contextId, text)"} + C -->|ok| DONE["written"] + C -->|violated by a cross-JVM race| REUSE +``` + +Two layers because each covers the other's blind spot: the lock is fast but only sees one instance, +the constraint is global but only fires after the fact. Together they make "the same fact, minted +twice" converge to one node no matter how the writes interleave. + +## Two-phase save: authoritative facts, append-only evidence + +A proposition's node and its entity mentions are *authoritative* — a save reflects the current truth, +so stale mentions should be reconciled away. Its provenance edges are *evidence* — the trail of where +the fact came from, which should accumulate, never silently shrink because a later lean save didn't +mention it. Those are opposite write semantics, so the save is split in two. + +```mermaid +sequenceDiagram + autonumber + participant Caller + participant Repo as Durable repository + participant Graph as Neo4j + Caller->>Repo: save(proposition) + Repo->>Graph: write node + mentions (DELETE_ORPHAN — authoritative) + Note over Graph: mentions no longer present are reconciled away + Repo->>Graph: write provenance edges (PRESERVE — append-only) + Note over Graph: existing evidence is never dropped by a lean save + Repo-->>Caller: saved +``` + +The consequence is that a routine save can't accidentally erase the evidence behind a fact. Replacing +provenance is therefore a *deliberate* act through explicit set/clear provenance calls — never a side +effect of an ordinary update. + +## Materialised effective confidence + +Confidence decays continuously from the moment a fact's content last changed, so the value you rank +and filter by — `effectiveConfidence()` — is a function of time, not a stored constant (see +[proposition-lifecycle](proposition-lifecycle.md)). Recomputing it per row on every query would be +slow and would push decay math into the database. Instead the graph keeps a **materialised** +`effectiveConfidence` column that the decay tick refreshes, and queries with the default decay +parameters push their threshold straight onto that column — fast, index-backed, all in the DB. + +The honest part is the fallback: a query asking for a *non-default* decay rate or an `asOf` in the +past can't trust the materialised column, so it pulls a candidate set from the DB and filters in +memory at the requested parameters. The fast path serves the overwhelmingly common case; the slow +path keeps the uncommon one correct rather than quietly wrong. + +## Schema as idempotent declarations + +Indexes and constraints aren't created by an imperative migration runner. They're declared as +`SchemaCatalog` beans — uniqueness constraints (the dedup backstop above, plus natural keys for the +lineage records), range indexes on the columns queries actually filter by, and a vector index on the +proposition embedding sized to the embedding model's dimension. Drivine applies them idempotently on +startup, so the same declarations are safe to re-run every boot. + +Declaring schema as data rather than steps means startup converges to the desired shape no matter the +prior state, and the natural-key uniqueness constraints are what let the lineage stores `MERGE` their +records — a replayed projection or collector record updates in place instead of duplicating. One +caveat worth stating plainly: changing the embedding model to one with a different vector dimension +requires dropping and recreating the vector index — re-embedding alone won't resize it. + +## The decay tick + +Decay only matters if something advances it. A scheduled tick materialises the cached confidence +column and then applies lifecycle transitions (ACTIVE→STALE and, if opted in, pruning). It's split +into its own configuration so `@EnableScheduling` is switched on *only* when decay is enabled, and it +resolves the decay manager lazily so it works regardless of which backend registered one. + +```mermaid +flowchart LR + T["@Scheduled tick
(default hourly)"] --> EN{"decay enabled?"} + EN -->|no| OFF["scheduling never switched on"] + EN -->|yes| MAT["materialise effectiveConfidence"] + MAT --> TRANS["apply lifecycle transitions
(ACTIVE → STALE)"] + TRANS --> PRUNE{"prune-stale?"} + PRUNE -->|false default| KEEP["leave STALE in place (reversible)"] + PRUNE -->|true opt-in| DEL["hard-delete STALE"] +``` + +The defaults are deliberately gentle — tick hourly, transition to a reversible `STALE`, and *don't* +prune unless a deployment opts in — so leaving DICE running doesn't quietly delete knowledge. The +tick interval, the decay-rate multiplier, and whether stale facts are pruned are all properties. + +## Configurable behavior + +Backend choice, every store bean, the schema catalogs, and the decay schedule are all overridable — +define your own bean and the autoconfig backs off. What ships is safe by default: in-memory unless +asked otherwise, dedup enforced in two independent layers, provenance never dropped by a routine +save, and decay that ages knowledge gently rather than deleting it.

The combined `span || role` find let an earlier role-matching mention win over the mention the span actually named, producing wrong-direction edges. - GraphProjectionService: isolate each lineage-record write so a flaky record store can't drop the trail for every remaining result after a mid-batch failure. - GraphQuery.whyExplain: honor the context scope on the global findById path so a context-bound query can't return foreign-context lineage. - GraphQueryCapable: the authority-aware overloads now throw when a backend sets honorsAuthorityFilter but doesn't override them, instead of silently returning unfiltered results. - InMemoryProjectionRecordStore: make the stale check-and-set atomic so concurrent calls don't double-count transitions. - Drivine projection/collector stores: skip and log a corrupt row rather than failing the whole all() query on one bad node. - RetrievalRouter.graphPath: log cross-context paths that are dropped so an empty result is distinguishable from a disconnected graph.

The all()-based SPI defaults are documented as a trivial-store fallback that durable stores MUST override. - Added a Neo4j integration test asserting findByContext returns only the requested context's records.

Populate it where each layer actually knows the source: - PropositionPipeline.processChunk stamps every proposition with a ProvenanceEntry(chunkId, contentHash). The locator is the caller's SourceAnalysisContext.sourceLocator when set, else a ContentAddressedLocator over the chunk text — always available and honest about what grounds the fact. Stamped before revision, so merges union it and a new proposition keeps it. - SourceAnalysisContext gains an optional sourceLocator + withSourceLocator. - LlmPropositionReviser unions provenanceEntries on merge/reinforce (deduped), mirroring the existing grounding union. - PropositionDto exposes provenance via a slim ProvenanceEntryDto. - TextIngestionHandler sets the locator on the context and lets the pipeline stamp once, instead of stamping by hand after extraction — provenance now has a single owner across every ingestion path. grounding: List is unchanged (backward compatible).

-Source: adversarial review of `embabel/dice#49` (`feat/graph-backend-and-retrieval`). - -## F-01: Discovery REST wiring is not safely auto-importable or context-safe - -Severity: high - -`DiscoveryController` is imported by `DiceRestConfiguration`, but the controller is only conditional on `PropositionStore`. Its constructor also requires `GraphQuery`, `ProjectionRecordStore`, and `CollectorRunner`. Storage autoconfiguration creates record stores, but does not create `GraphQuery` or `CollectorRunner`, so adding the optional REST config can break application startup for users who only have a proposition store. - -The controller also injects a singleton `GraphQuery` and then constructs per-request `RetrievalRouter` instances with a path `ContextId`. That cannot make the injected `GraphQuery` follow the request path, and is unsafe if a user supplies a scoped or differently configured `GraphQuery` bean. - -## F-02: Projection lineage can claim an edge was projected even when persistence failed - -Severity: high - -`NamedEntityDataRepositoryGraphRelationshipPersister` catches merge failures and returns aggregate `RelationshipPersistenceResult` counts, while `GraphProjectionService` records `ProjectionLifecycle.PROJECTED` for every successful projection result without checking whether the persistence step failed. A failed relationship write can therefore leave projection lineage and health reporting claiming an edge exists when it was not persisted. - -## F-03: Repository-backed reconciliation adopts endpoint nodes, not the projected relationship - -Severity: medium - -`RepositoryBackedReconciler` adopts the first existing resolved entity mention ID when projecting graph relationships. That treats reused endpoint nodes as if the relationship artifact already existed. A newly created edge can be recorded as `ADOPTED` against an endpoint node instead of `PROJECTED` against the edge target reference, which makes projection health and `findByTargetRef` semantics misleading. - -## F-04: Native graph-query capability has no context parameter - -Severity: medium - -`GraphQuery` routes to `GraphQueryCapable` native methods before applying the portable context-scoped query path. The native capability methods do not accept `ContextId` or a scoped `PropositionQuery`, so an adapter cannot honor the same context-isolation contract. `RetrievalRouter` can filter returned propositions after the fact, but it cannot prevent native traversal through foreign-context edges. From 08265fe2998f07ecfbfd55c42d8770906c8289cd Mon Sep 17 00:00:00 2001 From: James Dunnam <7660553+jimador@users.noreply.github.com> Date: Thu, 25 Jun 2026 21:04:56 -0400 Subject: [PATCH 22/22] fix(graph): harden persistence-failure attribution and close review test gaps A partial-failure batch the persister can't attribute per edge no longer paints a succeeded edge as FAILED: persistenceFailed now decides precisely when per-edge refs are present, and otherwise only fails an item when the whole batch failed. The shipped persister always reports refs, so production behaviour is unchanged; this fixes a custom or non-reporting persister mislabeling successes (and the null-relationship edge case). Tests: - GraphProjectionServiceLineageTest: a partial-failure batch marks only the attributed edge FAILED, and an unattributable partial failure marks no succeeded edge FAILED. - SeededGraphNoDuplicateNodesIT: findRelated now answers from the live container and a second projection of the same proposition is asserted ADOPTED, exercising the reconciler's adopt path against a real graph instead of an always-empty mock. - PropositionReviserTest: the reviser's reinforce path unions provenance (was only covered for merge). - ProvenancePopulationE2ETest: assert exactly one provenance entry, catching a double-stamp regression the prior any{} check would miss.
