Summary

Stops the maintainer comment gate from dismissing pr-review's approval on dev-lead:hands-off PRs whose only bot comments are no-finding summaries. A Codex or CodeRabbit summary now clears when the bot's own structured state says the review found nothing. SonarCloud's passed notice already cleared. Comments that report real findings still block.

Problem

On a dev-lead:hands-off PR, pr-review approves and then dismisses its own approval about a minute later ("Dismissing approval due to a PR issue comment lacking a verified disposition (#1813)"). This hit #2456 and #2467 on 2026-11-06.

Codex and CodeRabbit each keep one summary comment and edit it on every push. Under #2008 every edit needs a new dev-lead disposition reply. Dev-lead stays off a hands-off PR, so no reply is ever written. Maintainers must not forge the markers. The user approves as the same donpetry-bot account, so the next sweep dismisses their approval too. On #2467 the PR was only unstuck by removing hands-off and running dev-lead-retry.yml by hand three times.

Change

A Codex or CodeRabbit summary no longer needs a disposition when the bot's own structured state says its review found nothing. The match is on that state, never on prose. It holds however often the bot edits the comment. The new no_finding_summary jq predicate is in scripts/lib/maintainer-comment-gate.sh.

Bot	Clears only when
chatgpt-codex-connector	The body opens with <!-- codex-pull-request-review-summary --> and has exactly one codex-review-state:v1 JSON. In it the code review is completed, has_any_findings and has_unresolved_findings are both false, and commit_sha is 40 hex characters. The security review either never ran (all fields null) or completed the same way.
coderabbitai	The summary has exactly one final_review_risk_label field reading Merge Risk ⚪ Minimal, exactly one final_review_risk_coverage JSON with kind reviewed, and only passed pre-merge check badges.
sonarqubecloud	No change. The existing #1918 info_status_pattern already clears the passed notice.

Each case also requires all of the following, or the comment still blocks:

• The author is the GitHub App (author.__typename == "Bot"). A User account, another bot, or a missing type still blocks.
• No finding-bearing section (reviewer_sources_finding_section_pattern) is present.

Every other state still blocks: failed, in progress, findings present, unparseable, a duplicated state block, or a state quoted further down the body. CodeRabbit 🔵 Low still blocks too. In a sample of the last 40 PRs in five combsmith repos, every Low rating came with a stated follow-up.

The same predicate also filters the gate's sibling lists, so they cannot disagree with the gate:

• dev-lead's candidate list (maintainer_gate_open_comment_ids)
• the CodeRabbit's Security Architecture Review is throttled separately from its code review — findings in both sections must be addressed, and an in-place edit after disposition must re-open the comment #2008 re-open list (maintainer_gate_reopen_candidates)
• the stale-disposition sweep (maintainer_gate_stale_dispositions)
• the bot-comment retry (bcr_retry_decisions)

Nothing re-opens, chases or retries a summary the gate clears. ADR-0012 gains exemption 6, and docs/pr-review-agent/maintainer-comment-gate.md documents it.

Checked against 1,001 sampled bot comments: 28 Codex and 12 CodeRabbit summaries clear. Every Codex summary with findings or a failed review still blocks, as does every CodeRabbit summary rated Low, Moderate or High or with a failed, warning or inconclusive pre-merge check. The live #2467 and #2456 snapshots (all three bot comments unminimized, as during the deadlock) now return rc=0. Before this change they returned rc=1.

Sweep: one fix-bot-comment per PR per run (confirmed, not changed)

scan_pr_for_undispositioned_bot_comments dispatches only the oldest candidate (first(.[] | select(.decision == "dispatch"))). This is on purpose. Every retry joins the same per-PR concurrency lane, and a second dispatch would cancel the first while it is still pending. That is the loss #2017/#2262 recover from. The fix-bot-comment pass handles a single comment from start to finish: the intent payload, the prompt, the terminal marker and the retry dedup. Handling all comments in one run would need a multi-comment pass, which is a separate change. This PR takes the no-finding summaries out of the retry set entirely, so a hands-off PR no longer needs any retries for them.

Test plan

• tests/dev-lead/unit/test_maintainer_comment_gate.bats (+24 tests) covers:
  • the full hands-off fix(dev-lead-retry): CI-retry payloads carry the check run id and URL again #2467 snapshot (clears, and has nothing to disposition, re-open or chase);
  • Codex state variants;
  • CodeRabbit risk, coverage and pre-merge variants;
  • Sonar passed and failed notices;
  • author-type checks;
  • finding-bearing sections.
• tests/dev-lead/unit/test_bot_comment_retry.bats (+2 tests): no-finding summaries are not retry candidates; summaries with findings still dispatch.
• Live fixtures from fix(dev-lead-retry): CI-retry payloads carry the check run id and URL again #2467 and fix(maintainer-gate): bind info-status exemptions to the Bot author and body prefix #2456 are in tests/fixtures/{codex,coderabbit,sonarqubecloud}/. CodeRabbit's scope= link parameter is scrubbed.

Local runs used bash 5.3 (macOS /bin/bash 3.2 cannot parse comment-disposition-verify.sh on main). The gate suite passes 150/150. The sweep(#2262) tests in test_bot_comment_retry.bats also fail locally on unmodified main, so they are not affected by this change; CI is the reference for them.

Risk

Medium. The change is narrow, but it loosens an approval gate. A wrong match would clear a summary that should have blocked. The predicate limits that: Bot author only, structured state only, exact single fields, and the finding-section guard still applies. If Codex or CodeRabbit changes its state format, the predicate stops matching and the gate goes back to blocking (fail closed), never the other way.

Rollback

Revert this PR. The gate goes back to requiring a disposition per edit. No other side effects.

Monitoring

pr-review runs on hands-off PRs should stop logging skip: a PR issue comment lacks a verified disposition and stop posting "Dismissing approval due to a PR issue comment lacking a verified disposition (#1813)" when the only bot comments are no-finding summaries. dev-lead-retry.yml should stop dispatching fix-bot-comment for them.

Interaction contract

• N/A — this PR does not add or change an agentic role.

Design decision: no head-SHA check on no-finding summaries (maintainer-accepted)

no_finding_summary deliberately does not compare CodeRabbit's coveredCommitId or Codex's commit_sha with headRefOid. A summary that reported no findings for an earlier commit still clears the comment gate when the bot never reviewed the current head (for example, because it was rate-limited). This is intentional:

• Policy: we don't require every advisory reviewer to take part in every PR. A PR may merge while some bots are rate-limited.
• Consistent with the advisory gate: check_advisory_reviews (scripts/lib/advisory-review-gate.sh) already removes RATE_LIMITED or UNSUPPORTED bots from the required set (pr-review never auto-approves when advisory bots are rate-limited/out-of-quota — advisory-gate blocks on bots that can't submit #657). It proceeds on partial evidence after the 20-minute head-age or 10-minute quiescence timeout (pr-review advisory gate: timeout-proceed / skip absent advisory bots (durable hardening) #1193), and records it via _record_partial_evidence (pr-review has no false-negative metric and no production feedback loop — accepted defects found by advisory bots after approval are never counted or learned from #1596). It also counts a bot's latest submission whatever commit it covered. The rate-limited marker only schedules a sweep retry; it is not a hard hold. So no gate requires a bot to review the head, and requiring it here alone would bring back the deadlock this PR fixes, now for any rate-limited PR.
• Separation of concerns: the comment gate answers "does any bot comment still have an undispositioned finding?", not "did every bot review the head?" A stale summary that reports findings, or a Low/Moderate/High rating, still blocks. Inline findings remain review threads that need resolving.
• Backstop: pr-review itself always does a full review of the current head before approving.

The qa-lead advisory (stale-head clear) and pr-review finding 1 on 307098a are therefore accepted as designed. The fixture pr2467-summary-minimal-ratelimited.md clearing the gate is the intended behavior.

Release channel

This changes scripts/lib/maintainer-comment-gate.sh, scripts/lib/bot-comment-retry.sh and scripts/dev-lead-fix-reviews.sh. Merging to main alone does not activate it. It rides the Release Manager's next 4-hourly autocut to pr-review/v1-next and dev-lead/v139-next. That is when the deadlock fix takes effect here, because pr-review-trigger.yml pins @pr-review/v1-next. It reaches the consumer repos pinned to pr-review/v1-stable and dev-lead/v139-stable only through gated ring promotion.

Checklist

• shellcheck passes for the changed shell scripts (maintainer-comment-gate.sh, bot-comment-retry.sh).
• Docs updated where behavior or standards changed (ADR-0012, docs/pr-review-agent/maintainer-comment-gate.md).

QA Lead — test-risk advisory

Risk tier: MEDIUM. This loosens an approval gate. The negative-path coverage is strong (failed, running and findings states, duplicated or quoted state, author-type checks, finding sections, format drift that fails closed). But nothing ties the "no findings" state to the commit actually being merged.

What I'd shore up (highest leverage first):

• Stale-head clear. no_finding_summary checks that Codex commit_sha and CodeRabbit coveredCommitId look like 40-character SHAs, but never compares them to the PR head. check_maintainer_comments already fetches headRefOid. A summary that says "no findings up to X" still clears when the head is Y and the bot was rate-limited or failed on Y. The pr2467-summary-minimal-ratelimited fixture is exactly that case, and it is asserted to clear. Add a failing test (same body, head SHA ≠ covered SHA, result must be block), then compare to the head SHA in the predicate. Apply the same check to a completed Codex security review, which currently skips commit_sha.
• Parity across the five filters. Only the fix(dev-lead-retry): CI-retry payloads carry the check run id and URL again #2467 snapshot shows that the gate, the open-comment ids, re-open, stale-dispositions and the retry decision all agree. Run every fixture and every variant through a table-driven test that asserts the same clear/block result from all five.
• Unexplained local failures. The sweep(#2262) tests that "fail locally on main" are environment-dependent tech debt. Confirm they pass in CI under bash 5 and file a follow-up rather than leaving them as known failures.
• Monitoring. Log each clear (bot, comment id, covered SHA) so a format change or a stale clear shows up in a log.

Escalate? yes. A no-finding summary for an older commit can keep an approval on code no bot reviewed. A maintainer should decide on the head-SHA check before merge.

Advisory only — I comment, I do not change code. Ground: BMAD Test Architecture
(bmad-tea v1.19.0). Opt out on this item with the qa-lead:hands-off label.

The findings from the previous review (merge risk assessment) have been addressed in the current commit (307098a "fail closed on partial Codex security state; skip re-verify"). All security validation checks are in place: commit_sha is validated against code review, security_review fields are required to be explicitly present, and no-finding summaries are correctly excluded from re-verification. All tests pass including specific coverage for these scenarios.

Agent reasoning

**Issues addressed:** All dismissed review findings from previous commit (e3b434a) have been addressed in current HEAD (307098a):
1. ✅ **Security review commit SHA validation** — Fixed: Lines 207 in maintainer-comment-gate.sh now validate `$r.commit_sha == $sha` before accepting a clean state
2. ✅ **All-null security review check** — Fixed: Lines 200-201 require all four fields (`status`, `has_any_findings`, `has_unresolved_findings`, `commit_sha`) to be explicitly present via `has()` checks before validating all-null state
3. ✅ **Reverify list excludes no-finding summaries** — Fixed: Lines 2005-2007 in dev-lead-fix-reviews.sh now call `maintainer_gate_no_finding_ids` and exclude those IDs from re-verification  
4. ✅ **Tests strengthened** — Added comprehensive test coverage (tests 129, 130, 140, 141) for RESOLVED summaries edited after disposition, partial security review states, and mismatched commit SHAs
**Files changed:** All fixes in current HEAD (307098a):
- scripts/lib/maintainer-comment-gate.sh (security review validation, new `maintainer_gate_no_finding_ids` function)
- scripts/dev-lead-fix-reviews.sh (exclude no-finding summaries from reverify)

Summary

This PR adds a no_finding_summary jq predicate to scripts/lib/maintainer-comment-gate.sh. It clears a Codex or CodeRabbit summary comment when the bot's own structured state reports no findings. The same predicate filters dev-lead's candidate list, the #2008 re-open and stale-disposition lists, the bot-comment retry, and dev-lead's re-verify list. The aim is to stop pr-review from dismissing its own approval on dev-lead:hands-off PRs. The predicate is strict: a Bot author only, exactly one state block anchored at the top of the body, 40-hex SHAs, the finding-section guard, and an exact ⚪ Minimal label. About 24 new bats cases cover it, many of them negative paths. I agree with triage's MEDIUM rating. Triage did not catch one design question that the qa-lead persona explicitly left for a maintainer to decide. It is the only reason this review escalates.

Linked issue analysis

No linked or closing issue. The PR body explains the problem in full: the self-dismissal deadlock on PRs 2456 and 2467 on 2026-11-06. The change addresses it. Per its tests, the #2467 snapshot now returns rc=0, and it still blocks when Codex reports findings, CodeRabbit rates Low, Moderate or High, or Sonar fails.

Findings

1. [MEDIUM, blocking: maintainer decision needed] The no-finding state is never tied to the PR head.

• coderabbit_no_finding checks only that sourceCommitId and coveredCommitId are 40-hex.
• codex_no_finding checks only that code_review.commit_sha is 40-hex. The security review must match that SHA, but neither is compared with headRefOid.
• So a summary saying "no findings up to X" clears the gate when the head is Y and the bot never reviewed Y because it was rate-limited or failed.
• The fixture tests/fixtures/coderabbit/pr2467-summary-minimal-ratelimited.md is exactly that case ("Review limit reached" next to a Minimal rating for an earlier commit), and the tests assert it clears. The tests also hard-code 11929668… as the Codex commit_sha, which is not the snapshot's head.
• The qa-lead advisory (comment IC_kwDOR9SdIs8AAAABj1xGHQ) raised this and ended with "Escalate? yes … A maintainer should decide on the head-SHA check before merge."
• Neither the description nor any reply addresses it. CodeRabbit's description check noted the same omission. Commit 307098a fixed the four CodeRabbit findings but not this one.
• Possible mitigation (unconfirmed): pr-review's separate advisory-bot rate-limit hold may already withhold approval in this case. It posted such a hold on this PR at e3b434a. I could not read that code, so I cannot confirm it covers an edited CodeRabbit summary.
• To resolve, do one of these:
  • (a) Compare coveredCommitId and Codex commit_sha with the snapshot's headRefOid in the predicate, and add a failing test where the covered SHA differs from the head.
  • (b) Have a maintainer reply that accepts the gap and explains why, e.g. that the rate-limit hold covers it. Then re-request review.

2. [Resolved] CodeRabbit's four findings on e3b434a are fixed in 307098a. I checked each one against the diff:

• the security review must have the same commit_sha as the code review;
• all four fields must be present via has() before the all-null "never ran" case is accepted;
• maintainer_gate_no_finding_ids is excluded from reverify_ids in dev-lead-fix-reviews.sh;
• a RESOLVED, edited CodeRabbit summary is tested in both the reopen and stale filters.

CodeRabbit's inline replies acknowledge the fixes. Its summary still shows Moderate for e3b43 because it was rate-limited and never re-ran on 307098a.

3. [Info] Correctness spot-checks (by reading only; I did not run them).

• jq precedence in no_finding_summary and in the .author?.login // "" | tostring chains is correct.
• . as $l | keeps the comment as input for the recognizers.
• The pre-merge badge scan matches both badge forms (pre-merge-checks-passed.svg and counter-passed-14), not the pre_merge_checks_walkthrough markers.
• maintainer_gate_no_finding_ids … || true fails safe: an error re-verifies more, never less.
• The fixtures redact CodeRabbit's scope= parameter (scope=REDACTED in both).

4. [Low, non-blocking] Release channel not stated. AGENTS.md requires saying which channel(s) must carry a scripts/ change and when. The downstream-impact report lists 8 consumer repos pinning dev-lead-reusable.yml and pr-review.yml. Please add a line, e.g. "rides the next autocut to pr-review/v1-next and the dev-lead -next channel".

Not verified:

• scripts/ is not in the review workspace, so I could not read the unchanged callers (_maintainer_gate_finding_re, the sourcing in bot-comment-retry.sh) or the rate-limit hold logic.
• I could not run shellcheck or bats.
• The MCP secret-scanning tool was not available. CI gitleaks passed.
• Review-thread resolution state was not in the pre-fed metadata. The dev-lead logs and CodeRabbit's replies say all threads were addressed.

CI status

All required checks pass on 307098a: SonarCloud, CodeQL, agent-shield / AgentShield, dependency-audit / Detect ecosystems and duplicate-decl-gate. shellcheck, ShellCheck, bats, unit-tests, unit, Lint, actionlint, Secret scan (gitleaks) and the validate-* jobs also pass. The CANCELLED entries are all superseded dev-lead / *, review / review and Dismiss orchestration runs, not CI. CodeRabbit is NEUTRAL because it was rate-limited. Merge state is BLOCKED only on REVIEW_REQUIRED.

Review mode: triage-approved (single reviewer)

Summary

This PR adds a no_finding_summary jq predicate to scripts/lib/maintainer-comment-gate.sh. The predicate clears a Codex or CodeRabbit summary comment when all of these hold:

• the author is a GitHub App (Bot);
• the bot's own structured state says its review found nothing;
• the body has no section that reports findings.

The same predicate filters four other lists, so none of them can disagree with the gate:

• dev-lead's candidate list;
• the #2008 re-open list and the stale-disposition sweep;
• the bot-comment retry;
• dev-lead's re-verify list.

The aim is to end the self-dismissal deadlock on dev-lead:hands-off PRs.

The head is still 307098a, the commit the cycle-1 review escalated. No code has changed since then. The maintainer answered both open findings by editing the PR description, which was the path the prior review offered. I agree with the triage rating of MEDIUM: the change is narrow but loosens an approval gate. I found nothing new that blocks.

Linked issue analysis

No issue is linked or set to close. The PR description fully covers the problem (PRs 2456 and 2467 deadlocked on 2026-11-06), the change, its risk, rollback, monitoring and release channel. Per its tests, the change fixes the deadlock: the #2467 hands-off snapshot now returns rc=0. It still blocks when:

• a Codex summary reports findings;
• CodeRabbit rates the merge risk Low, Moderate or High;
• a pre-merge check is not passed;
• the Sonar quality gate fails.

Findings

1. [Resolved: maintainer-accepted design] The no-finding state is not tied to the PR head. The PR description now has a section titled "Design decision: no head-SHA check on no-finding summaries (maintainer-accepted)". It says leaving out the check is intentional and accepts both the qa-lead advisory and this finding from the prior review. Judged on the merits, the reasoning holds:

• The comment gate answers "does a bot comment have an undispositioned finding?", not "did every bot review the head?".
• Requiring the summary to cover the head would bring the deadlock back for any PR where the bot was rate-limited.
• A stale summary that reports findings, or any rating other than Minimal, still blocks.
• Inline findings remain review threads.
• pr-review always reviews the current head in full before it approves.

Unconfirmed: the description says check_advisory_reviews already accepts partial evidence and a bot's latest submission from any commit (#657, #1193, #1596). scripts/ is not in the review workspace, so I could not read that code.

2. [Resolved] Release channel. A new Release channel section says the change rides the Release Manager's autocut to pr-review/v1-next and dev-lead/v1-next. It reaches v1-stable, v139-stable and the 8 consumer repos in the downstream-impact report only through gated ring promotion. This meets the AGENTS.md requirement.

3. [Resolved earlier] CodeRabbit's four findings on e3b434a. Commit 307098a fixed all four:

• a completed security review must carry the same 40-hex commit_sha as the code review;
• all four security-review fields must be present (has()) before the all-null "never ran" case is accepted;
• the re-verify list skips maintainer_gate_no_finding_ids;
• tests now cover an edited, RESOLVED CodeRabbit summary in both the re-open and stale filters.

CodeRabbit's replies on the inline threads acknowledge the fixes, and its review is DISMISSED.

4. [Info] Correctness spot-checks. I checked these by reading the code; I did not run anything.

• Every jq program that now includes _MAINTAINER_GATE_NO_FINDING_JQ_DEFS also binds $findre: the gate, the open-comment ids, re-open, stale-dispositions, no-finding ids and bcr. If one did not, jq would fail to compile.
• Operator precedence is correct. // binds tighter than |, and and binds tighter than | in the coverage check. jq's and short-circuits.
• If the coverage JSON is null or unparseable, .kind and nf_sha are falsy, so the summary blocks (fails closed).
• The pre-merge badge scan handles both the passed.svg and counter-passed-14 badge forms, and unique == ["passed"] needs at least one badge.
• maintainer_gate_no_finding_ids … || true fails safe: on an error dev-lead re-verifies more comments, never fewer.
• The fixtures redact CodeRabbit's scope= parameter.

Not verified:

• I could not run shellcheck or bats. CI ran both and they pass.
• The callers this PR does not change were not readable: _maintainer_gate_finding_re, the sourcing in bot-comment-retry.sh, and the advisory-gate behaviour the design note cites.
• The MCP secret-scanning tool was not available. The gitleaks check passed.
• Whether review threads are resolved is not in the pre-fed metadata. The dev-lead logs and CodeRabbit's replies say every inline thread was answered.
• The "maintainer-accepted" statement comes from the PR author's own description. The author is an org MEMBER, and dev-lead:hands-off keeps dev-lead off this PR.

CI status

Every real check passes on 307098a, including:

• SonarCloud (Quality Gate passed, 0 new issues), CodeQL and Analyze (actions and python);
• shellcheck, ShellCheck, bats, unit-tests, unit, Lint and actionlint;
• Secret scan (gitleaks), agent-shield / AgentShield and Agent Security Scan;
• dependency-audit (Detect ecosystems and Audit gate) and duplicate-decl-gate;
• the validate-* and stub-guard jobs.

The CANCELLED entries are only superseded dev-lead / dispatch and Dismiss orchestration runs. CodeRabbit is NEUTRAL because it was rate-limited. Merge state is BLOCKED only because a review is required (REVIEW_REQUIRED).
