Closes #2169 only after source repair and exact-head acceptance.

Current state

SOURCE_REPAIRED / FULL_SUITE_DEPENDENCY_REPAIRED / CURRENT_MAIN_RECONCILED / PARTIAL_EXACT_HEAD_GREEN

Exact head: c346b8324fa23e23d4007799d26ad3a8ac6ae4c3.
Base: protected main@91be6442906c7b6b4f600272c953699708394327.

Required OpenCode Review can fail coverage-evidence before its model review exists. The prior scheduler ignored every CheckRun from that workflow, so a source-backed coverage failure could not reach bounded RCA. The executable scheduler contract admits only failed Required OpenCode Review / coverage-evidence through the retained OpenCode-workflow provenance guard; failed opencode-review, same-named checks from another workflow, unknown provenance, and stale failures superseded by newer pending/successful attempts remain excluded. Coverage thresholds and provider/model policy are unchanged.

The full-suite runner dependency repair also remains intact: a scheduler-only review_repair_suite run must install the Noema document hashed dependency lock because the intentionally unscoped full-suite collection imports the document path. The fix extends only that dependency-install predicate and retains the full-suite gate.

That dependency repair has independent hosted reproduction from sibling owner #1629. On #1629 exact db3d648c905d283f03fc16fbc9891ba76edd56b8, Runtime Quality 34826203993 reached a real hosted runner and failed in review-repair pytest collection after the changed-path selection skipped the Noema document dependency install; eleven Noema-related modules failed import because scripts/ci/noema_review_document.py requires defusedxml. This validates #2170's dependency predicate as a foundation prerequisite rather than authorizing a duplicate patch in #1629. Correct order is #2170 normal protected integration, then ordinary/non-force #1629 reconciliation and entirely fresh exact-head acceptance.

Protected main advanced through #2194. Reverse helper #2199 ordinary-merged main@91be644... into this canonical branch. No force-push/destructive rebase was used and no predecessor acceptance evidence transfers.

Fresh exact-head hosted acceptance

On unchanged exact c346b832...:

  • Agent Review Runtime Quality CI 34826735972: SUCCESS;
  • SAST Semgrep 34826735939: SUCCESS;
  • Security Scan 34826736000: queued;
  • Python Security 34826735889: queued;
  • CodeQL PR 34826735991: queued.

The predecessor head's GREEN lanes remain historical after reconciliation. A qualifying independent approval must also bind this exact head. Do not manually rerun, add a no-op wake commit, synthesize status, narrow the full-suite gate, weaken a security/review threshold, transfer predecessor evidence, force-update, or bypass merge.

Explanation

직접 연결된 이슈 #2169의 핵심 소스 수정이 없습니다. PR diff는 테스트 파일만 추가합니다. scripts/ci/pr_review_fix_scheduler.py는 여전히 Required OpenCode ReviewRCA_IGNORED_WORKFLOW_NAMES에 포함하고, current_head_failed_checks()에서 해당 워크플로의 coverage-evidence 실패를 제외합니다. 따라서 새 테스트의 필수 기대값인 RCA 분류가 구현되지 않습니다. 새 테스트는 실패 계약을 기록하지만 실제 repair_mode=rca 디스패치 경로를 수정하지 않습니다. 또한 newer pending 시도가 stale failure를 대체하는 테스트와 exact-head, deduplication, live-head 보호의 회귀 검증이 포함되지 않습니다.

Resolution

current_head_failed_checks()에 check-name-aware 예외를 추가하여 Required OpenCode Review의 source-backed coverage-evidence 실패만 허용하십시오. opencode-review, metadata-only, queue-controller 실패는 계속 제외하십시오. newer 성공 또는 pending 시도가 이전 실패를 대체하는 동작과 exact-head, deduplication, live-head 보호를 검증하는 회귀 테스트를 추가하십시오. 기존 임계값, synthetic status, provider fallback, self-approval 동작은 변경하지 마십시오.

Exact-head review at 7cda25c8b903108051e0d1d78e49d2b692a94a4a.

The original RED is now repaired at the causal scheduler boundary. coverage-evidence alone is admitted as source-backed pre-review RCA evidence through the retained OpenCode-workflow guard; opencode-review remains excluded by check name, so the control plane does not recursively repair its own model-review failure. The new pending-attempt contract also proves an in-progress newer run retires stale failure evidence until terminal, matching the existing latest-attempt semantics.

Mechanical compare from 67dfa048446c96d99e3db2ebacdc02d16ed6294e is one commit ahead / zero behind and changes only scripts/ci/pr_review_fix_scheduler.py by +5/-1. No threshold, provider, model, status, or workflow-name weakening was introduced.

This is a COMMENT, not approval or merge authorization. Fresh hosted workflows on this exact head are still acceptance-pending.

Exact-head review at d3f1d0264912e74b897fdf2a0a6085100de4e40a after provenance tightening.

The earlier source repair was intentionally strengthened rather than rewritten. RED d01316990c9410165736ef09f0ab9979241078e8 proves that an identically named failed coverage-evidence from OpenCode Review must remain excluded. Production now admits only the exact authoritative pair Required OpenCode Review / coverage-evidence; opencode-review, other OpenCode-family workflows, and unknown workflow provenance remain outside bounded RCA admission. Pending and successful newer attempts still retire stale failure evidence.

Mechanical compare from the strengthened RED is one commit ahead / zero behind and changes only scripts/ci/pr_review_fix_scheduler.py by +4/-2. No threshold, provider/model, synthetic status, manual rerun, or broad workflow exclusion weakening is present.

Fresh hosted checks on this exact head are queued. This COMMENT is not approval, GREEN evidence, or merge authorization.

Ordinary non-force restack for #2170 after protected main advanced through #2172. Preserve both histories; exact-head acceptance restarts.

Noema LLM review

The PR routes Required OpenCode Review coverage-evidence failures to RCA while preserving exclusions for other workflow names and the opencode-review orchestrator status. The new regression tests cover admission, cross-workflow exclusion, non-recursion, pending supersession, and success supersession. The workflow change ensures review-repair full-suite runs install Noema document dependencies when review_repair is selected. All adversarial probes falsified regression hypotheses; no blocking issues found.

Reviewed changed lines

  • scripts/ci/pr_review_fix_scheduler.py:288 (LEFT): Old condition excluded all ignored workflows; new logic adds an override for the authoritative source-backed pre-review check pair.
  • scripts/ci/pr_review_fix_scheduler.py:291 (RIGHT): Authoritative pair ('Required OpenCode Review', 'coverage-evidence') is admitted despite workflow being in the ignore set, routing its failure to RCA.
  • scripts/ci/pr_review_fix_scheduler.py:294 (RIGHT): Cross-workflow override is scoped to the exact tuple, so non-authoritative workflows remain excluded; opencode-review orchestrator remains non-recursive.
  • scripts/ci/pr_review_fix_scheduler.py:103 (RIGHT): Frozenset contains exactly one tuple, preventing accidental admission of other workflow/check pairs.
  • .github/workflows/agent-review-runtime-quality-ci.yml:351 (RIGHT): OR condition installs Noema document dependencies when review_repair is selected, backed by new regression test.
  • tests/test_pr_review_fix_scheduler_required_opencode_coverage_rca.py:93 (RIGHT): Pending supersedes stale failure; latest IN_PROGRESS attempt retires older FAILURE evidence in both current_head_failed_checks and needs_rca_repair.

Adversarial validation

  • scripts/ci/pr_review_fix_scheduler.py:291 (RIGHT) falsified: Non-authoritative workflow 'OpenCode Review' with check 'coverage-evidence' might leak into RCA routing due to the new override. — RCA_SOURCE_BACKED_PRE_REVIEW_CHECKS contains only ('Required OpenCode Review', 'coverage-evidence'); override is False for 'OpenCode Review', so workflow remains ignored and current_head_failed_checks returns ().
  • scripts/ci/pr_review_fix_scheduler.py:293 (RIGHT) falsified: An 'opencode-review' orchestrator failure might trigger recursive RCA dispatch. — Override tuple only matches 'coverage-evidence', so the opencode-review orchestrator remains in the ignored set; current_head_failed_checks() and needs_rca_repair(False, ()) hold.
  • scripts/ci/pr_review_fix_scheduler.py:294 (RIGHT) falsified: A stale FAILURE followed by a newer IN_PROGRESS attempt might still be treated as failed, causing premature RCA dispatch. — latest_check_run_attempts deduplicates by created_at; the newer IN_PROGRESS attempt has conclusion=None, so it does not match FAILED_CHECK_CONCLUSIONS and current_head_failed_checks returns ().
  • .github/workflows/agent-review-runtime-quality-ci.yml:351 (RIGHT) falsified: The OR condition might break noema-only installs or omit required dependency provisioning for review-repair-only runs. — Condition noema == 'true' || review_repair == 'true' executes install when review_repair is true; new regression test asserts both terms and requirements-noema-document-ci-hashes.txt appear in the same step.
  • scripts/ci/pr_review_fix_scheduler.py:288 (LEFT) falsified: The change might accidentally admit all checks in the ignored workflow, not just coverage-evidence. — The frozenset override only matches the exact tuple ('Required OpenCode Review', 'coverage-evidence'); other names remain excluded by the ignored workflow rule.
  • tests/test_pr_review_fix_scheduler_required_opencode_coverage_rca.py:93 (RIGHT) falsified: The new tests might not actually exercise production deduplication and could pass vacuously. — Fixture builds two coverage-evidence checks with distinct created_at; production dedupe selects the newest attempt; assertions on current_head_failed_checks() == () and needs_rca_repair(False, ()) cover the supersession contract.
  • Residual risk: Low residual risk: the production scheduler has a separately tracked RED unrelated to this PR; the frozenset override is intentionally narrow, but future additions of similar tuples must be reviewed for unintended workflow admissions.

Protected main advanced from 828eaaefb0cc97bba4da63eb9270447476d26710 to ebc69a4016f7668beaef5e3b592d378f22ada684 through #2123 while this lane was pending. I treated that as an intervening authoritative delta, not a race.

The protected-main delta touches only opencode-review-dispatch.yml, CHANGELOG/doctoring/gap baseline, and its two trust-boundary tests; the #2170 source delta touches only the runtime-quality workflow, RCA scheduler, and its two regression tests. Because the path sets are disjoint, I adopted protected main with an ordinary two-parent commit c741b608322208b8bc222792ceb3b6c63207e157 (ae0f2f57... first parent, ebc69a401... second parent), then fast-forwarded the PR branch without force.

Mechanical compare now reports protected main@ebc69a401... as the merge base, 0 commits behind, with the same four #2170 files as the only net PR delta. Fresh exact-head runs have been generated: Runtime Quality 34790741479, Security 34790741442, Python Security 34790741469, Semgrep 34790741487 are queued and CodeQL 34790741484 is pending. The earlier Noema approval is bound to predecessor ae0f2f57... and is therefore historical evidence only; this new exact head still requires fresh terminal checks and qualifying independent review.

This COMMENT records the non-force restack and current acceptance boundary. It is not approval or merge authorization.

Coordination/docs-to-code finding: PR metadata is now exact c741b608322208b8bc222792ceb3b6c63207e157 on protected main@ebc69a4016f7668beaef5e3b592d378f22ada684, but the body still declares ae0f2f57... / 828eaaef... as current authority and lists predecessor workflow outcomes. Please currentize the owner body without a source-neutral commit; exact-head runs 34790741479/34790741487/34790741442/34790741469/34790741484 are still queued, so no acceptance transfer is valid.

Ordinary/non-force merge of protected main into the canonical #2170 branch. Preserves the coverage-RCA and full-suite dependency repair with current protected advances; predecessor check/review freshness does not transfer.

Fresh dependency coordination finding: protected .github/main is now 91be6442906c7b6b4f600272c953699708394327, one ordinary commit beyond this PR's 7f070293... base. The protected advance changes OpenCode/Pingora policy paths, while #2170's effective four paths are agent-review-runtime-quality-ci.yml, the review-fix scheduler, and its two focused tests, so no path overlap is present. Preserve both histories with an ordinary/non-force restack when the central owner lane is free; do not close, force-rebase, synthesize status, or transfer the current-head acceptance after movement. Current mergeable=false is therefore a repair/restack finding, not a retirement signal.
