Independent closer audit at e85730eThe newer keepalive commit adds seven regression cases only. Independent Cursor review via Orchestrator confirms the real harvested benchmark-to-preparation path and all three stale rollback guards. Local checks: 75 promotion/harvester tests, 4 workflow/context tests, Ruff, Black target py312 and diff check pass.
Reran cancelled Gate run 34910335102 on e85730e; ledger and lint now passed, Python matrix was still running at inspection. No merge or auto-merge authorization. Source design #2819 stays closed as instructed. |

CI disposition preserved in corpus evidencePushed Validation: 90 passed across harvester, promotion preparation, workflow wiring and verifier terminal-disposition suites. Actual CLI roundtrip covers CI true/false/missing/unknown and the production fetch/parser/partition. Ruff and Black py312 pass, mypy passes all three production modules, full actionlint with the checked-in allowlist passes, strict template completeness passes, and diff checks are clean. The initial regression failed against the prior publisher; restored implementation passes. The separate seven-test keepalive addition was also audited. The CI dispatch fix restarts normal exact-head checks/review. Push observed by 2026-09-15T00:34:59.854181+00:00; conservative review floor 2026-09-15T00:41:59.854181+00:00. Do not merge or arm auto-merge before that floor; restart it after any later push. Provenance thread r4002514074 remains unresolved for independent acceptance of this correction; the description and rollback findings were independently dispositioned in comment5672827038. Source2819 remains closed; the metadata-generated broad-design checklist is not evidence of current recovery acceptance. |

Independent closer acceptance at 925a74cProvenance finding r4002514074 is satisfied. I inspected the production publisher, workflow context wiring, comment parser, record join, partition and case identity. The comparison job passes trusted Independent local validation: 116 focused harvester, promotion, workflow and backplane tests passed. Replacing only the publisher with its pre-fix e85730e version made all four production subprocess roundtrip cases fail; byte-restoring the current publisher made all four pass. This covers CI true/false/missing/malformed, live-fetch parsing and partition behavior. The latest 925a74c commit changes only promotion tests to exercise the actual CLI, exit signals, deterministic date and unchanged registry on failed gates; these tests passed. Worktree/diff checks are clean. Merge gates: all 106 paginated current-head check contexts passed or legitimately skipped; required The latest head was committed at 01:00:18Z and its current successful Gate completed at 01:10:25Z, beyond the seven-minute review floor. I am resolving the remaining outdated provenance thread based on this independent evidence, then re-querying exact head, all review threads and checks immediately before guarded squash merge. Closed design #2819 will stay closed; post-merge verify:compare must still disposition this bounded recovery. |

Those workflows already exist on Source context: Closing reference #2819 is the closed design epic. Per standing closer instruction, broad design #2819 stays closed; this merge addressed bounded corpus-evidence correctness only (publisher CI_FAILED floor, harvester provenance join, promotion regression tests). Provider split: Anthropic PASS (62%) explicitly notes epic checklist vs narrow diff mismatch. OpenAI CONCERNS (84%) are the same scope-category disagreement, not a reproducible code defect on the merged commit. Disposition: Treat verifier |
The harvester could turn a stable merge into benchmark PASS without a verifier decision. This recovery joins the actual comparison verifier report to the exact repository/PR, head, evaluated merge, run and attempt before admitting a case. It also preserves the verifier CI-failure guard: raw provider PASS cannot override failed merge CI, and missing CI context cannot publish benchmark evidence.
Related to the already-closed design #2819.
Scope
Acceptance and validation
No broad design reopening or live model-policy promotion is claimed. See durable recovery comments for prior 13 provenance-mutation failures, three promotion regression failures and full JavaScript evidence; see the latest CI-disposition comment for this head's exact review floor.
