Tasks

• Update .github/workflows/maint-77-model-registry-freshness.yml to dispatch .github/workflows/maint-78-model-evaluation-pilot.yml when a new catalog candidate passes freshness screening.
• Extend tools/harvest_verifier_corpus.py and .github/workflows/maint-79-verifier-corpus-harvest.yml to join verifier decisions to realized PR outcomes with stable case identities.
• Extend tools/prepare_model_promotion.py and .github/workflows/maint-86-model-promotion-prepare.yml so same-family, non-increasing-cost candidates can prepare bounded promotion PRs while riskier swaps remain approval-gated.
• Add rollback metadata and quality_gate_breach handling to .github/workflows/maint-86-model-promotion-prepare.yml without weakening config/model_selection_policy.json.
• Add the end-to-end regression cases to tests/tools/test_harvest_verifier_corpus.py, tests/tools/test_prepare_model_promotion.py, and tests/workflows/test_model_eval_pilot_workflow.py.

Acceptance criteria

• python -m pytest tests/tools/test_harvest_verifier_corpus.py tests/tools/test_prepare_model_promotion.py tests/workflows/test_model_eval_pilot_workflow.py -q passes with non-zero collection.
• A new catalogued model results in an auto-dispatched pilot with itself added as a candidate — no human trigger, no manual candidate edit.
• Live pr_verifier decisions + realized PR outcomes accumulate labeled paired cases into the approval corpus automatically (test: N simulated decisions+outcomes produce N corpus cases with correct labels).
• A candidate meeting all gates on ≥75 auto-harvested cases, same-family + cost≤, produces an auto-promotion PR; a cross-family/pricier candidate produces an approval-required PR.
• A post-promotion quality_gate_breach auto-reverts to the prior selection.
• Policy gates + human-approval-for-risky-swaps remain unchanged.

Closer review-thread disposition (cursor closer)

Audited the harvest diff and tools/harvest_verifier_corpus.py routing on exact head after rebasing onto current main.

CodeRabbit count mismatch (14 vs 18)

The commit adds 14 new staging records (9× stranske/Workflows, 1× stranske/Trend_Model_Project, 4× stranske/Fine-Art-Archive). The walkthrough’s “18” figure was incorrect; there are no missing records in this diff. Case IDs added: workflows-2981…workflows-2993, trend_model_project-5799, fine-art-archive-470…fine-art-archive-474.

Copilot staging vs frozen-corpus concern

This PR is staging-only by design for this harvest run. partition() routes clean-pass cases with confidence: low (merged younger than stability_days) into the auto-expiring staging file; only confidence: high cases promote into config/model_eval_pilot.json. A fresh dry-run on this head reports 0 promoted, 156 staged, and this PR intentionally contains no pilot-corpus edits because none of the newly harvested cases cleared the stability window yet.

Rebased branch onto current main (f294b789); fresh CI required before merge. Both threads are dispositioned as satisfied with this evidence.

[stranske]

Absent-check record (pre-merge)

gh pr checks lists what did report, so a check that never started is missing from the list, not red. Running the absent-check comparison by hand for this head (the check_checks_reported.py reporter is hardcoded to stranske/Orchestrator and does not cover this repo):

• Reported on head f294b789: 35 check-runs + 2 commit statuses (Gate / gate success, CodeRabbit success). 26 pass / 15 skipping / 0 fail / 0 pending.
• Reference set: check-run names reporting on ≥6 of the last 8 merged PRs (chore(main): release 1.32.2 #3400, fix(gate): survive a fork PR's read-only token when writing the Gate status #3398, chore(main): release 1.32.1 #3397, fix(repo-review): restart repo analysis on head drift #3396, fix(repo-review): fail closed on incomplete docs drift #3395, fix(sync): preserve current Claude review action pin #3393, config(models): refresh stale OpenAI pricing and record the Astra CLI-version constraint #3390, fix(sync): renew the sealed delivery Gate trigger #3388) → 36 names.
• Absent on this head: gate and auto-pilot — 8/8 on the reference set, 0 here.

Disposition — structural, not a verification gap. Both names are jobs of Agents Auto-Pilot (.github/workflows/agents-auto-pilot.yml). Its pull_request trigger is types: [labeled, closed] — it does not subscribe to synchronize. This head was produced by the rebase force-push, not by a label event, so those two jobs could not have run on it. The reference PRs carry them because a label event fired on their final head. No workflow was deleted, held, cancelled or path-filtered away, and neither name is a required check — branch protection requires summary, which reported and passed (run 34134676295).

Confirmed on head f294b789 by workflow run: Gate, Agents PR meta manager, Health 40/44/45/50/52, Maint 52, PR 11, Selftest CI all completed success; PR 46 Dependency Repair Contract completed skipped. Agents Auto-Pilot has no run on this SHA, as its trigger set predicts.

Merging on that basis. Zero active non-outdated review threads; MERGEABLE/CLEAN; post-push review window elapsed (push 14:45Z, head unchanged on re-read).

• Model: gpt-5.6-terra
• Verdict: FAIL
• Confidence: 95%
• Scores:
  • Correctness: 4.0/10
  • Completeness: 1.0/10
  • Quality: 7.0/10
  • Testing: 1.0/10
  • Risks: 4.0/10
• Summary: The JSON additions are syntactically simple and appear stylistically consistent with the existing staging corpus, but they are only a static corpus update. The documented acceptance criteria require implementation and regression coverage across harvesting, pilot dispatch, promotion preparation, approval gating, and rollback workflows. Those required code and test changes are absent, so the PR does not fulfill the stated acceptance criteria.
• Concerns:
  • The change only appends static entries to config/model_eval_corpus_staging.json. It does not implement or modify the required automatic join between live pr_verifier decisions and realized PR outcomes in tools/harvest_verifier_corpus.py or maint-79-verifier-corpus-harvest.yml.
  • None of the required workflow behavior is addressed: no freshness-triggered pilot dispatch, candidate injection into the pilot, tiered promotion handling, rollback metadata, or quality_gate_breach-triggered reversion is implemented in this diff.
  • The required promotion-policy behavior cannot be established from these data-only changes. There are no changes to tools/prepare_model_promotion.py, maint-86-model-promotion-prepare.yml, or policy-preserving enforcement logic.
  • No regression tests were added or updated in the three explicitly required test files. In particular, this diff does not demonstrate N simulated decisions/outcomes yielding N correctly labeled corpus cases, auto-promotion for qualifying same-family/cost-nonincreasing candidates, approval gating for risky swaps, or rollback behavior.
  • The appended cases contain stable-looking case_id values, but only record PASS/clean-pass labels and do not include verifiable decision/outcome linkage metadata in the change. The diff therefore provides no evidence that these labels were automatically derived from realized outcomes rather than manually curated.

• Scores:
  • Correctness: 3.0/10
  • Completeness: 1.0/10
  • Quality: 5.0/10
  • Testing: 0.0/10
  • Risks: 3.0/10
• Summary: This PR adds only static data (126 new JSON case entries) to config/model_eval_corpird_staging.json with zero code or test changes. None of the required task items (workflow dispatch logic, corpus harvesting tool extensions, promotion tool extensions, rollback/quality_gate_breach handling, or new regression tests) are present in the diff. While CI passed, that reflects existing test suites unaffected by this change rather than validation of the described acceptance criteria, which explicitly call for new/updated test files that are absent here. The PR does not implement or verify the auto-dispatch, auto-harvest, auto-promotion, or auto-rollback behaviors specified in the linked issue/PR description, so it fails to meet the stated acceptance criteria as a standalone change.
• Concerns:
  • The diff only adds static JSON entries to config/model_eval_corpus_staging.json (126 lines of data); it contains no changes to tools/harvest_verifier_corpus.py, tools/prepare_model_promotion.py, or any of the referenced workflow files (maint-77, maint-79, maint-86).
  • None of the required test files (tests/tools/test_harvest_verifier_corpus.py, tests/tools/test_prepare_model_promotion.py, tests/workflows/test_model_eval_pilot_workflow.py) were added or modified, so the acceptance criterion requiring these tests to pass with non-zero collection cannot be verified from this PR.
  • The acceptance criteria describe substantial new automation behavior (auto-dispatch pilot on new catalog candidate, auto-harvesting corpus with stable case identities, tiered auto-promotion vs approval-gated PRs, quality_gate_breach auto-revert) — none of this logic is present in the diff.
  • The PR title/scope ('harvest realized-outcome verifier cases') suggests this is meant to be a narrow follow-up populating corpus data, but it is being evaluated against a much broader design issue's acceptance criteria which it does not satisfy.
  • CI success reported is generic (lint, JS tests, Python tests) and does not confirm the specific pytest invocation named in the acceptance criteria actually exercises new functionality, since no corresponding code changes exist.
  • Risk: harvested data entries are unverifiable from the diff alone (no code to establish provenance/join logic), raising questions about how these case entries were generated without corresponding tool changes in this PR.

Closer verifier disposition — FAIL is a false positive caused by a wrong source binding on this PR

Provider Comparison (2026-09-07T15:03:49Z) returned FAIL from both providers (openai 95%, anthropic 85%). Both graded this PR against issue #2819's five tasks and six acceptance criteria — workflow dispatch logic, promotion tiering, rollback metadata, three named test files — and correctly observed that a 126-line append to config/model_eval_corpus_staging.json satisfies none of them.

The PR was never supposed to be graded against #2819. This is the weekly maint-79-verifier-corpus-harvest.yml job on branch verifier-corpus-harvest/auto. Its only job is to append realized-outcome cases to the staging corpus. #2819's implementation landed on 2026-07-25 (#2831, #2832) and the issue was CLOSED on 2026-08-15, three weeks before this PR opened. The verifier is holding a recurring data job to the acceptance criteria of a finished design epic.

The binding is new and is a regression. The six prior harvest PRs on this same branch carry no meta:issue marker and no closing reference:

PR	Opened	meta:issue	Closes #N
#3402	2026-09-07	2819	yes
#3291	2026-08-31	none	no
#3233	2026-08-24	none	no
#3135	2026-08-17	none	no
#3026	2026-08-10	none	no
#2906	2026-08-03	none	no
#2843	2026-07-27	none	no

The workflow's own body text (maint-79-verifier-corpus-harvest.yml:73) says only "Automated corpus growth (#2819 move 2)" — a provenance mention in owner/repo#N form, which source_context.js:206-212 explicitly skips (token.includes('/'), and the preceding character is a word character). Neither that workflow nor source_context.js / agents_pr_meta_update_body.js / agents-pr-meta-v4.yml has changed since 2026-08-24, so the mechanism is not yet identified.

Disposition: no code remedy on this PR, no follow-up PR against #2819. The merged content is correct — 14 harvested clean-pass cases, all expected_verdict: PASS, provenance: harvested, consistent with the 1,279 lines already in the file. #2819 stays closed; it is not reopened on the strength of a FAIL that was measured against the wrong contract. Merging did not misclose anything because #2819 was already closed — but the identical binding on an open epic would have closed it on a JSON append, which is why this is filed rather than just annotated: see #3407.

Closer lane, 2026-09-07. Verified against the merged diff, the six prior harvest PRs, issue #2819's state, and the commit history of all four pr-meta binding files.
