Understanding

Ticket-045 deliberately stopped at the contract boundary. The pipeline already persists a manifest on its success/degraded path and through one shared failure handler, so the smallest runtime slice is one codec/writer plus two call sites in that persistence boundary. GitHub events occur after or outside the pipeline and therefore belong to a later workflow-level producer, not an append to this immutable run log.

Execution plan

1. Obtain explicit approval for the runtime scope and local identity fallback.
2. Implement one closed parser/validator/renderer with deterministic hashes.
3. Add same-directory temporary write, validation and atomic rename.
4. Register and write logs.dsl.txt after succeeded/degraded and failed manifests without changing the public pipeline result type.
5. Prove canonical-fixture compatibility, negative validation, determinism and all three pipeline outcomes.
6. Run focused, full host, governance and Docker checks, then publish one exact-head reviewable PR.

Actual changes

• Human approval received; ticket transitioned from PLAN / WAIT_FOR_APPROVAL to IN_PROGRESS / EDIT.
• Architecture and implementation budget are accepted; source and test work is starting inside that boundary.
• Code inspection found that approved post-run actions mutate only manifest.files; hashing the complete file would make a correct immutable log stale. The implementation therefore hashes an allowlisted stable projection while retaining all semantic run and audit fields.
• Split persistence acquisition from the codec after the first implementation reached 580 lines; both modules now remain cohesive and below the repository GOD-file threshold within the global five-file budget.
• Kept merge evaluation out of the pipeline stream: this producer observes analysis and diagnostics but has no authority to claim ALLOWED.
• Implemented the closed codec, SHA-256 evidence/event chain, strict parser, safe evidence references and same-directory atomic publication.
• Integrated immutable logs for succeeded, degraded and failed pipeline runs; receipt registration is covered by a regression proving the stable manifest projection remains valid.
• Focused tests (15/15), full verification (396 passed, 1 JDK-local skip), deterministic governance, Docker smoke and diff checks all pass.
• Triaged the advisory Koru report: compiler-proven Buffer/Uint8Array and never findings were false positives, while its persisted-state consistency and new-test cleanup observations were accepted and corrected.
• Replaced a secret-shaped literal in a negative query-reference fixture after Validator App correctly enforced the repository’s patch secret heuristic; the test still proves that all query-bearing evidence references fail closed.
• The first hosted Koru report rejected two inherited deterministic metrics in the touched runPipeline function (CC=65, 372 lines). Refactored only the approved run.ts path into bounded internal stages without suppression or a public API change; local Lizard now reports a maximum CC=5 and 20 lines.
• Re-ran the 15 focused tests, full verification, governance, Docker smoke and whitespace validation after the refactor; all deterministic gates pass.

Blockers

• None. Koru passed, Validator App approved exact head 1180e45, all protected checks passed, PR #62 merged as main@c1decdb, and the implementation branch was deleted.
