fix(review-graph): preflight worker publication contracts

[acgetchell]

Compact review workers could omit required optional coverage fields, publish artifact references that compilation rejected, or synthesize duplicate and contradictory evidence rows. Dispatches now expose the relevant shapes and examples, and publication validates artifact references and synthesis bindings before writing.

• Include the complete optional coverage shape, including dependency_uncertainty and one-based finding indices, while retaining strict partition and reuse rules.
• Require exact declared validation artifact roots, including external logs; reject child paths and absent outputs with actionable diagnostics while preserving runtime snapshot verification.
• Verify synthesis against compiled predecessor artifacts and a digest-bound plan. Report binding errors together, clarify shared validators and merged requirements, and distinguish fresh acceptance from proved reuse. Document separate bounded schema and semantic metadata corrections.

Validation: just test-python passed 1,294 tests with two platform-specific skips. Python formatting, lint and type checks, Markdown checks, skill validation, Semgrep scanning and rule tests, and tool-pin checks passed.

The paired scripted benchmark preserved all four seeded findings and published/compiled all nine partitioned audits on their first attempt. Total worker input grew 5.0%, with no increase in coordinator operations. This measures protocol behavior, not model retry rates or hosted-platform execution.

Closes #126
Closes #130
Closes #131

Summary by CodeRabbit

• Validation
  • Validation artifact references must match permitted artifact roots; unknown or absent artifacts are rejected before publication.
  • Compilation uses persisted worker results and runtime snapshots, with acceptance checks applied to the resulting evidence.
• Synthesis
  • Validation reports multiple binding issues together, including duplicate requirements and conflicting or missing evidence.
  • Synthesis publication checks evidence against its bound plan and source artifacts.
• Documentation
  • Updated guidance clarifies artifact references, evidence placement, optional coverage partitions, publication checks, and retry limits.

Walkthrough

The review-graph runtime now describes optional coverage partitions and synthesis evidence, binds publication checks to dispatch inputs, and rejects invalid validation artifact references before payload writing. Synthesis validation reports collected blockers. Benchmark replay metrics and tests cover these changes.

_{A rabbit checks each path with care,
And binds the plan to evidence there.
Partitions count, findings stay,
Blockers gather on the way.
Nine audits publish in line,
Then compile with roots aligned.
I thump and mark the contract fine.}

- Around line 3861-3866: Update the external-metadata continuation flow around
_restart_reused_metadata_audits and resume_after_external_metadata so a changed
plan is published to a new artifact store rather than materialized over or
alongside immutable files in the existing store. Update the continuation’s
artifact-store and plan references to point to the new store.
