Delivery context

The cross-repository integration hub is genlayerlabs/genlayer-node#1835

Closes GVM-323

Problem and outcome

Fee configuration and results used positional bucket indexes, while several v0.3 outbound-message reserve rules had drifted from consensus

This stack moves fee accounting to named buckets and aligns message accounting with consensus, including compact leader-output encoding, submitted-message caps, retained-output RAM, allocation matching, timeout bounds, and per-message declared budgets

Known non-goal: the reveal leg still shares the single-round execution_data_gas limit and requires a follow-up fix. The too_many_rounds behavior is intentionally unchanged

Implementation and validation

  • Uses named bucket maps through manager and executor interfaces
  • Keeps exactly 1 commit in the manager and each executor repository
  • Pins both executor lines and includes generated ABI and specification updates
  • Enforces separate propose and commit timeout bounds with the both-zero opt-out
  • Computes each internal declaredBudget as minPrimaryFees + sum(direct child budgets) for both acceptance and finalization; external messages declare zero
  • Treats zero-budget internal allocation nodes as absent while preserving external allocation behavior
  • Charges nondeterministic outputs using a conservative compact LeaderPublicData size estimate
  • Leaves descendant capacity across repeated novel acceptance executions explicitly unspecified
  • Passed the debug build, codegen check, complete commit-hooks pipeline, documentation build, 92 Rust unit targets, and 255 v0.3 message and balance integrations
  • Latest focused validation passed 126 v0.3 executor library tests and all 12 output-cap leader/validator/sync scenarios
  • Independent re-review found no blockers

Risk is concentrated in fee-host configuration compatibility: v0.3 hosts must provide the 4 phase-timeout bounds. No persisted-data migration is required; rollback is commit-level

Full E2E has not been requested yet

Summary by CodeRabbit

  • Breaking Changes

    • Fee accounting now uses named buckets instead of positional arrays.
    • Leader public data uses calldata-encoded maps.
    • Message allocation encoding and node ordering have changed.
    • Legacy method-key rewriting is no longer supported.
    • Storage access bounds now use storage-slot length.
  • New Features

    • Added named-bucket fee reservations and allocation-funded internal-message accounting.
    • Added event-based fee rules, array startup deductions, and nested-run fee handling.
    • Added separate validation for timeout ranges, execution budgets, and rotation limits.
  • Documentation

    • Updated fee specifications, manager API schemas, execution results, and changelog with the revised behavior.

📝 Walkthrough

Walkthrough

The change replaces positional fee-bucket data with named maps, updates allocation ABI encoding to breadth-first traversal, revises fee and timeout rules, updates result specifications, and aligns executor references and cross-major tests.

Changes

Fee model and execution format update

Layer / File(s) Summary
Named fee data and allocation ABI contracts
crates/modules-interfaces/src/domain.rs, crates/modules-interfaces/src/domain/fees/*, implementation/src/manager/run.rs, docs/website/src/impl-spec/appendix/manager-api.yaml, docs/website/src/spec/03-vm/05-result.rst
Fee totals and remaining balances now use bucket-name maps. Wildcard call keys use keccak256(""). Allocation trees encode from a matched root in breadth-first order.
Fee configuration and allocation matching
docs/website/src/impl-spec/04-fees.rst, docs/website/src/spec/02-execution-environment/03-wasi_genlayer_sdk/02-gl_call.rst
The fee rules document named buckets, allocation-funded budgets, startup deductions, gross-up behavior, and timeout and budget validation errors.
Result format, version behavior, and integration updates
docs/website/src/spec/changelog.rst, executors/v0.2.x, executors/v0.3.x, .genvm-tool.py
The changelog records result and fee-model changes. Executor references advance, and cross-major system tests select executor major version 3.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 7fc4d

This changes fee and executor integration behavior, but the external-message fee example remains inconsistent and the v0.3 executor release artifact cannot currently be downloaded through the manifest-derived URL. Resolve both before merging to avoid incorrect fee guidance and broken package generation.

the matched node’s budget and rejected with an allocation-budget error when it
exceeds that limit. Remove the capping behavior and preserve declaredBudget at
its exact calculated value for valid allocations.

- Line 267: Update the internal branch of the executable configuration’s fee
calculation to use minPrimaryFees(feeParams), while preserving the existing
external-message calculation. Ensure the example derives internal primary
reserve from the documented minimum-fee calculation rather than node.gasInternal
and rotation count.
- Line 267: Update the message_fee expression so its external-message branch,
where a.isInternal is false, returns literal zero instead of multiplying
gasLimit by maxGasPrice; preserve the existing internal-message calculation
using node.gasInternal and rotation count.
