fix(maintainer-gate): bind info-status exemptions to the Bot author and body prefix - #2456
The maintainer comment gate lets a registered bot's no-finding notice through with no disposition (#1918, #1995). Two examples are SonarQube Cloud's "Quality Gate passed" summary and Codex's usage-limit notice. The gate tied that exemption to the bare login only. It never checked that the author was the bot.
GitHub has an ordinary User account named sonarqubecloud. That account could post the passed-gate text on any PR and clear the gate. The Sonar pattern was also unanchored, so it could match the passed-gate text anywhere in a body.
I replayed the gate against the live #1421 comments at the channel commit that dismissed the approval (cd02e25, run 41829975366). Both notices were already exempt, minimized or not:
IC_kwDORyesfc8AAAABipnEHw (Sonar)
IC_kwDORyesfc8AAAABgQo7fQ (Codex)
The blocker I can reproduce is CodeRabbit's summary IC_kwDORyesfc8AAAABgQo8PA. It was edited at 2026-11-04T01:45:48Z, after its latest covering disposition, so #2008 re-opened it as designed. This PR does not change that path.
Change
scripts/lib/maintainer-comment-gate.sh
New check. A shared jq definition, info_status_clear, follows the same style as review_request and opted_out. It clears a comment only when all of these hold:
author.__typename == "Bot"
the login, with any [bot] suffix removed, has a registered info_status_pattern
the body matches that pattern
the body has no finding-bearing section
A missing __typename is not Bot, so the comment stays blocked (fail closed).
One definition for both callers.check_maintainer_comments and maintainer_gate_open_comment_ids both use info_status_clear, so they cannot drift apart.
Author type lookup.maintainer_gate_merge_edit_times now also reads author{__typename} in its existing GraphQL pass and merges it into the snapshot. gh pr view --json comments does not expose the author type. The value from the API overrides anything already in the snapshot.
Warning.check_maintainer_comments logs a warning when a comment from a registered info-status login has no author type. That makes a stall on clean notices easy to diagnose.
scripts/lib/reviewer-sources.tsv: the sonarqubecloud pattern is now anchored to the passed-badge prefix every SonarQube Cloud gate comment opens with. I checked 43 Sonar comments across 40 org PRs, and all start with it. The zero-issue and zero-hotspot requirements are unchanged. The Codex pattern was already anchored at the body start.
Docs: the gate doc and ADR-0012 state the Bot-author requirement.
No other exemption path changes. maintainer-resolve-comment.sh already required a Bot actor for its bot path.
Call sites
Both callers already supply the author type:
Caller
Where the author type comes from
Guard
pr-review, scripts/review-one-pr.sh
The gate runs on the output of maintainer_gate_merge_edit_times, which now selects author{__typename}
Existing wiring test (#2008) checks the merge runs before the gate. The merge test's gh shim now answers only a query that selects author{__typename}, so dropping it fails the test.
Its issue-comment query already selects author{login __typename}
New wiring test
Risk
The risk is medium. Every change makes the gate stricter, and every failure mode fails closed.
The worst case is that clean Sonar or Codex notices block again on a PR. That would happen if the author-type lookup fails, or if a vendor changes its badge URL. The fix then is the old manual step: minimize the notice as RESOLVED, or add <!-- maintainer:not-a-finding -->. No path clears a comment it did not clear before.
This library reaches consumers through the dev-lead and pr-review reusables.
Test plan
New cases in tests/dev-lead/unit/test_maintainer_comment_gate.bats use the verbatim #1421 bodies. Each case checks both the gate verdict and dev-lead's candidate list.

After promotion, watch pr-review logs for these two lines:

Make the merge-helper test fail when the GraphQL query omits author{__typename}.
The gh shim at tests/dev-lead/unit/test_maintainer_comment_gate.bats:884-886 returns the same response for every call and ignores its arguments. If author{__typename} is removed from the query at scripts/lib/maintainer-comment-gate.sh:347, the shim still supplies __typename, and this test still passes. The classifier tests set __typename directly, so no test checks the outgoing query. The new exemption then fails closed for clean Bot notices without a test failure.
Add a guard that fails the shim when the query lacks the selection. The .comments[0].author assertion fails in that case:

Risk tier: LOW. This change makes a merge-gate control stricter, and every new condition fails closed. If any of these gaps ship, the result is extra blocking (the #1421 friction coming back), not a bypass. The bypass itself (a User account holding a bot's login) is covered by tests at both decision points: the gate verdict and dev-lead's candidate list.
What I'd shore up (highest leverage first):
Test the failure path of the fail-closed claim. The new maintainer_gate_merge_edit_times test only covers the success path. Add a gh shim that exits non-zero or returns malformed JSON. Assert that the snapshot comes back byte-identical and that the Sonar notice then blocks. The PR description promises this behaviour, but no test checks it.
Test pagination of the __typename merge. Add a two-page shim (hasNextPage: true) where the Bot comment is only on page 2. If the merge silently drops page 2, a long PR blocks again on notices that should clear.
Watch for pattern drift. The Sonar pattern now depends on the …/v2/checks/QualityGateBadge/qg-passed-20px.png URL. If SonarQube Cloud bumps the badge path, the notice goes back to blocking with no signal. Note in reviewer-sources.tsv that a new blocking passed notice means the vendor changed the badge format.

Summary
This change tightens the gate and I found no way for it to fail open. An info-status exemption now needs a GraphQL-sourced author.__typename == "Bot", a registered login, a matching anchored pattern and no finding section, and the gate and dev-lead's candidate filter share one definition. I am escalating instead of approving for three reasons: the required CI was unfinished at 66ce130, including the bats suite that carries the new security tests; I could not check that every caller merges __typename before the gate runs; and the PR description lacks the required risk, rollback and monitoring sections. I rate the risk MEDIUM, not the combined HIGH, because every failure mode I can see fails closed. The worst case is merges stalling on clean bot notices, not the gate being bypassed.
Downstream impact
This change is consumed by 8 downstream repo(s) that pin the affected reusable workflow / lib / prompt. Impacted consumers:
info: The core check is sound. info_status_clear requires (.author?.__typename // "") == "Bot", so a missing type, null, User, Mannequin or EnterpriseUserAccount all fail closed. The [bot] suffix cannot be spoofed, because [ and ] are not allowed in GitHub usernames and App slugs are globally unique. So Bot plus a bare login points to exactly one GitHub App. jq's and short-circuits, so a null $p never reaches test($p). check_maintainer_comments and maintainer_gate_open_comment_ids both call the same _MAINTAINER_GATE_INFO_JQ_DEFS, which removes the drift risk the old duplicated inline filters carried. (scripts/lib/maintainer-comment-gate.sh:67)
info: The __typename value cannot be injected. It comes only from the GitHub GraphQL author{__typename} field. The merge (.author // {}) + {__typename: $t[.id]} puts the API value on the right, so it overrides anything already in the snapshot. The base snapshot comes from gh pr view --json comments, which returns only author.login. A comment the GraphQL pass did not return keeps no type and blocks. The new merge is nested inside the existing $m | has($id) branch, and both maps come from the same nodes, so they stay consistent. (scripts/lib/maintainer-comment-gate.sh:104)
major: Required CI was not finished at head 66ce130. These were IN_PROGRESS or QUEUED: Lint/'bats', Test Dev-Lead Agent/'unit', 'stub-structure', 'pr-auto-review-stub', 'auto-rebase-retry-resilience', Lint/'validate-eval-cases', 'gh-aw-compile', and CodeRabbit. The new bats cases are the only executable evidence for this authz fix. They cover a User holding a bot login, a missing type, swapped bots, a non-prefix body and the __typename merge. They have not been seen to pass on Linux. The author's local bats run on macOS is not authoritative. Do not merge until these are green.
minor: UNCONFIRMED. The new ^## [
minor: The safety check reports 4 of 5 required description sections missing: risk, test-plan, rollback and monitoring. No issue is linked. This shared library ships to 8 consumers through the dev-lead and pr-review reusables. Under AGENTS.md, autocut and canary promotion carry it there, and rollback is a channel move back to an earlier immutable tag. The description should give that rollback path and a monitoring signal, for example clean Sonar or Codex notices newly blocking the gate after promotion. The dev-lead:hands-off label does not stop the promotion gate.
info: The exposure being closed was limited. Any GitHub User named sonarqubecloud or chatgpt-codex-connector could post a matching body on this public repo, and that comment was exempted. The old $findre check already stopped such a comment from carrying a finding section, so the realistic impact was a skipped disposition, not a forced merge. The PR removes that path without widening any other exemption. in_gate_scope and the opt-out and marker paths are unchanged in this diff.
info: No workflows, actions, dependencies or secrets are touched. Gitleaks, CodeQL, AgentShield, dependency-audit and the Agent Security Scan passed. The safety check found no CI weakening, prompt injection or secret forwarding. The diff adds only public SonarSource badge URLs and regex text. Codex, at this head, and SonarQube Cloud reported no findings. CodeRabbit was still processing.
info: I could not fetch CODEOWNERS or CONTRIBUTING via gh api, read the call sites in scripts/, or run shellcheck or bats. No shell or network was available. The review used the pre-fed diff and metadata, plus the AGENTS.md in the workspace.

…nd body prefix
The info-status exemption (#1918, #1995) cleared a comment on its bare login
and pattern alone. A User account can hold a registered bot's login (a User
named `sonarqubecloud` exists), so the SonarQube Cloud "Quality Gate passed"
text from that account cleared the gate. The Sonar pattern was also unanchored.
- Add info_status_clear, a shared jq definition used by both
check_maintainer_comments and maintainer_gate_open_comment_ids. It requires
author.__typename "Bot" (missing type fails closed), the registered pattern,
and no finding-bearing section.
- maintainer_gate_merge_edit_times also merges author.__typename from its
existing GraphQL pass, since gh pr view does not expose it.
- Anchor the sonarqubecloud pattern to the passed-badge prefix.
- Tests use the verbatim combsmith/.github#1421 notices: both clear from the
Bot; a failed Sonar gate, a Codex review, a User or different bot posting
the same text, and a missing author type all still block.

…okup query in tests
- check_maintainer_comments logs a warning when a comment from a registered
info-status login carries no author type, so a stall on clean notices
(author-type lookup missing or failed) is diagnosable.
- The merge-helper test's gh shim answers only a query that selects
author{__typename}, so dropping the selection fails the test (CodeRabbit).
- A wiring test pins dev-lead's issue-comment fetch to select __typename.

#2444 switched the redispatch job to GH_TOKEN: ${{ github.token }}. The job
token can start workflow_dispatch runs, and GH_PAT_WORKFLOWS is being retired
(#1326). The test still required secrets.GH_PAT_WORKFLOWS, so bats has failed
on main since #2444. It now asserts the redispatch job sets GH_TOKEN from
github.token and that the workflow no longer references GH_PAT_WORKFLOWS.

Summary
I agree with the triage assessment. An info-status exemption now needs all of: a Bot author type taken from GraphQL, a registered login, a matching anchored pattern, and no finding-bearing section. The gate and dev-lead's candidate filter now use one shared definition. I found no path where the change fails open. The new head also resolves the call-site, anchoring and description findings from the prior review (66ce130).
I am escalating instead of approving for one reason. At d27c67f, the two suites that run the new tests were still IN_PROGRESS: Lint / bats and Test Dev-Lead Agent / unit. Those tests are the only executable evidence for this authorization fix, and unit also contains the new dev-lead wiring test. If both pass, nothing I found blocks the merge.
Linked issue analysis
No closing issue is linked. The PR refers to #1918, #1995 and #2008, which created the exemption, and to combsmith/.github#1421, which motivated this fix. The description covers the problem, the change, call sites, risk, test plan, rollback and monitoring. The code matches the stated problem: a User account holding a bot's login no longer clears the gate, and the Sonar pattern is anchored to the start of the body. The author says that the blocker they could reproduce on #1421, the edited CodeRabbit summary, is out of scope for this PR. The missing link does not block on its own.
Findings
Prior-review findings
Resolved in tests, pending CI (was major): call sites unconfirmed. This head adds three things:
The gh shim in the merge test now exits 1 unless the query selects author{__typename}, so dropping that selection from _gql fails the test (tests/dev-lead/unit/test_maintainer_comment_gate.bats:438). This also covers CodeRabbit's nitpick.
A new wiring test checks that dev-lead-fix-reviews.sh selects author{login __typename}.
A new log_warn fires when a registered info-status login has no author type (scripts/lib/maintainer-comment-gate.sh:625).
Carried forward, blocking (major): required CI is not finished. Lint / bats and Test Dev-Lead Agent / unit are still IN_PROGRESS at this head. All other checks that were pending at the last review have now passed, including stub-structure, pr-auto-review-stub, auto-rebase-retry-resilience, validate-eval-cases and gh-aw-compile. Do not merge until both suites are green.
Resolved, not confirmed by running it (was minor): ^ anchoring. jq compiles regexes with Oniguruma's Perl_NT syntax, which turns on the single-line option, so ^ matches only at the start of the string. The existing Codex pattern already relies on this. The new test for a Sonar passed summary that does not open the body checks it directly, and that test runs in the pending bats suite.
Resolved (was minor): description sections. The safety check now reports DESCRIPTION_MISSING: 0. The rollback steps match the AGENTS.md channel-move procedure, and the monitoring section names concrete log lines to watch.
New at this head
info: The __typename merge is correct (scripts/lib/maintainer-comment-gate.sh:386).
. + {lastEditedAt: …} | if … runs inside the then branch, and the API value on the right overrides anything already in the snapshot.
A null GraphQL author stays untyped (fixture IC_g), and an id that GraphQL did not return keeps no type (fixture IC_y).
If the snapshot author is null but GraphQL returns a type, the result is {__typename} with no login. No pattern is found for it, so it is not cleared and the gate fails closed.
info:info_status_clear is sound. jq's and short-circuits, so test($p) never receives a null pattern. The [bot] suffix cannot be spoofed, because GitHub usernames cannot contain [ or ]. Both callers share the definition, so they cannot drift apart.
info: This PR's own SonarQube Cloud comment, posted by the sonarqubecloud login, opens with the exact badge prefix the new pattern requires. That is consistent with the author's survey of 43 Sonar comments. The comment is already minimized as RESOLVED.
minor (does not block): The PR does not add the QA-lead advisory's other test suggestions:
a failure-path test where gh exits non-zero, the snapshot comes back unchanged and the notice blocks;
a two-page pagination test for the __typename merge.
A comment past any page cap in maintainer_gate_merge_edit_times would also have no type and would block. All of these gaps fail closed, causing extra blocking and never a bypass. They are cheap follow-ups.
minor (does not block): The new untyped-author warning also counts comments that are minimized RESOLVED or outside the gate's scope. dev-lead's maintainer_gate_open_comment_ids path has no equivalent warning. This affects diagnostics only.
info: The tests/test_feature_ideation.bats change is unrelated to the PR title. It is in its own commit and the description explains it. The test now matches fix(feature-ideation): re-dispatch only for authors with write access #2444: the redispatch job uses GH_TOKEN: ${{ github.token }} and no reference to secrets.GH_PAT_WORKFLOWS remains. If the job is renamed, the awk extraction fails loudly at [ -n "$job" ]. I could not read feature-ideation.yml, so I have not confirmed that the workflow matches. I also could not check the claim that bats has been failing on main.
info: The PR changes no workflows, actions, dependencies or secrets. The safety checks are clean: no CI weakening, no prompt injection and no secret forwarding. gitleaks, CodeQL, AgentShield and Agent Security Scan all pass. Codex finished with no findings at this head, and SonarQube Cloud's quality gate passed.
info: The MCP secret-scanning tool was not available in this run, so I skipped that scan. I could not run shellcheck or bats, or read the call-site scripts, because I have no shell or network access.

Summary
I agree with the triage. This change only makes the comment gate stricter. A clean status comment from a bot (such as SonarQube Cloud's passed notice) is exempt only when all of these hold:
GitHub's API reports the author type as Bot.
The login is registered.
The body matches the registered pattern, which is now anchored to the start of the body.
The body has no section that reports a finding.
The gate and dev-lead's candidate filter now use one shared check, info_status_clear. I found no way for the change to let a comment through that was blocked before. Every failure path keeps the comment blocked.
The head has not changed since the cycle-2 review (d27c67f). That review had one blocking finding: two test suites were still running. Both have now passed (see CI status). That was the only thing blocking, so I am approving.
Linked issue analysis
No issue is linked with a closing keyword. The PR refers to #1918, #1995 and #2008, which set up the exemption, and to combsmith/.github#1421, which prompted this fix. The code does what the description says:
A User account that holds a bot's login no longer clears the gate.
The Sonar pattern is anchored to the badge image at the start of the body.
A comment with no author type still blocks.
The description also covers risk, call sites, test plan, rollback and monitoring. This is a hardening fix written up in full, so the missing link does not block on its own.
Findings
Prior-review findings
Resolved (was blocking, major): required CI not finished. Lint / bats passed at 20:31:17Z and Test Dev-Lead Agent / unit passed at 20:33:06Z, both at this head. These suites hold:
the new tests for a User holding a bot login, swapped bots, a missing author type, and a passed notice that does not open the body;
the test that the __typename merge runs, with a gh shim that fails if the query does not select author{__typename};
the new wiring test on dev-lead's comment query;
the corrected test_feature_ideation.bats.
Confirmed by CI (was major, unconfirmed): call sites. I could not read scripts/ from the review workspace. The passing unit suite runs the wiring test showing that dev-lead-fix-reviews.sh selects author{login __typename}, and the existing #2008 test that the merge runs before the gate in review-one-pr.sh. The suite names suggest which files they run; I did not read the workflow definitions. The prompt copy in this workspace, prompts/dev-lead/fix-reviews.md:145, also selects author{login __typename}.
Resolved (was minor): ^ anchoring. jq's regex engine (Oniguruma) treats ^ as the start of the string, not the start of any line. The test for a Sonar passed summary that does not open the body passed in bats.
minor: The QA-lead advisory suggested two more tests, and neither was added:
a failure-path test: gh exits non-zero, the snapshot comes back unchanged, and the notice blocks;
a two-page pagination test for the __typename merge.
Both gaps can only cause extra blocking, never a bypass.
minor: The new warning about comments with no author type also counts comments that are already minimized as RESOLVED or out of the gate's scope. dev-lead's maintainer_gate_open_comment_ids path has no matching warning. This only affects diagnostics.
minor: The Sonar pattern now depends on SonarQube Cloud's v2/checks/QualityGateBadge/qg-passed-20px.png badge URL. If the vendor changes it, clean notices will block again until the registry is updated. The monitoring section names the log lines to watch for this.
Security and correctness checks
info:info_status_clear requires (.author?.__typename // "") == "Bot", so a missing, null, User or other author type fails closed. jq's and stops early, so test($p) never gets a null pattern. The [bot] suffix cannot be spoofed, because GitHub usernames cannot contain [ or ].
info: The author type comes only from the GraphQL author{__typename} field. The merge puts the API value on the right, so it overrides anything already in the snapshot. A null GraphQL author stays untyped, and a comment that GraphQL did not return keeps no type. Both stay blocked.
info: No workflows, actions, dependencies or secrets are changed. The safety checks found no CI weakening, no prompt injection and no secret forwarding. This PR's own SonarQube Cloud comment opens with the exact badge prefix the new pattern requires. Codex finished with no findings at this head. CodeRabbit's one nitpick, a shim guard on the query, was applied.
info: Downstream impact: 8 consumer repos pick this library up through dev-lead-reusable.yml and pr-review.yml. Rollout goes through canary promotion, and the description gives the channel-rollback steps.
info: The dev-lead:hands-off label is present. It does not affect this review.
Not verified
The MCP secret-scanning tool was not available, so I skipped that scan. gitleaks passed.
I could not run shellcheck or bats, or read the scripts in scripts/ or CODEOWNERS, because I have no shell or network access. For those I relied on the CI results above.
Review-thread resolution state was not in the pre-fed metadata. No review requested changes. The only human-authored comments are review requests and an advisory QA-lead note marked "Escalate? no".

pr-review approved on PARTIAL advisory evidence: 2/5 required advisory bots reported before the gate's head-age-timeout fallback proceeded. Recorded for the miss-rate metric (#1596).
The automated review withdrew its approval while this PR was in the merge queue, and no other approval stands for the current head commit d27c67fcb72d0f2b03f0aa82f603d5e4880bbff9. GitHub checks reviews only when a PR joins the queue, not when the queue merges it, so the PR was removed from the queue to stop it merging without an approval.
What happens next: the PR needs an approval for its head commit again. Address the review findings, or a maintainer approves it. Once an approval stands, dev-lead re-enables auto-merge on its next pass and the PR rejoins the queue; a maintainer can also re-add it by hand.
CodeRabbit's summary review confirms all changes are well-formed and all pre-merge checks pass with minimal merge risk — no actionable code issues found.

## Summary
**Bot:** chatgpt-codex-connector[bot]
**Issues addressed:** 0 (neutral overview — no findings)
**Disposition:**
- Code review summary (no findings): disposition=informational
**Files changed:** None (no code changes needed — the bot comment is a clean status summary)
**Details:**
The bot's code review completed with no findings (`"has_any_findings":false`). The comment is a neutral overview showing the review status, not an actionable finding. Since it doesn't match the bot's registered `info_status_pattern` (which only auto-clears usage-limit notices), it required a manual `informational` disposition. Posted disposition reply to clear the maintainer-comment gate.

Summary
I agree with the triage. This PR only makes the maintainer comment gate stricter. A clean bot status notice is exempt only when all of these hold:
GitHub's GraphQL API reports the author type as Bot.
The login, with any [bot] suffix removed, is registered.
The body matches the registered pattern. The Sonar pattern is now anchored to the badge at the start of the body.
The body has no section that reports a finding.
The gate and dev-lead's candidate filter now use one shared definition, info_status_clear. I found no path that clears a comment the old code blocked. Every failure path, such as a failed lookup, a missing author type or a changed vendor badge, keeps the comment blocked.
The head has not changed since the cycle-2 review. The cycle-2 approval was later withdrawn and the PR was taken out of the merge queue. Since then, dev-lead has posted informational dispositions for the CodeRabbit summary (23:18Z on Nov 5) and the Codex review summary (03:21Z on Nov 6), and both comments are minimized as RESOLVED. I think those two edited bot comments caused the withdrawal, but I have not confirmed it. Nothing in the code or CI has changed, so I am approving again.
Linked issue analysis
No issue is linked with a closing keyword. The PR refers to #1918, #1995 and #2008, which set up the exemption, and to combsmith/.github#1421, which prompted this fix. The code does what the description says:
A User account that holds a bot's login no longer clears the gate.
The Sonar pattern is anchored to the start of the body.
A comment with no author type still blocks.
The description covers problem, change, call sites, risk, test plan, rollback and monitoring. The safety check reports DESCRIPTION_MISSING: 0. For a hardening fix written up this fully, the missing link does not block.
Findings
Prior-review findings
Resolved (was blocking): required CI not finished. Lint / bats passed at 20:31:17Z and Test Dev-Lead Agent / unit passed at 20:33:06Z, both at this head. These suites contain:
the tests for a User holding a bot login, swapped bots, a missing author type, and a passed notice that does not open the body;
the __typename merge test, whose gh shim fails if the query does not select author{__typename};
the dev-lead wiring test;
the corrected test_feature_ideation.bats.
Covered by CI, not read (was major): call sites.scripts/review-one-pr.sh and scripts/dev-lead-fix-reviews.sh are not in the review workspace, so I did not read them. The passing unit suite contains the wiring test showing that dev-lead's query selects author{login __typename}. The PR says the #2008 test, which checks that the merge runs before the gate, is also in that suite.
Resolved (was minor): ^ anchoring. The test for a passed notice that does not open the body passed in bats.
Correctness checks at this head
info:info_status_clear (scripts/lib/maintainer-comment-gate.sh:67) tests (.author?.__typename // "") == "Bot" first. A null, missing, User or other author type therefore fails closed. jq's and stops at the first false operand, so test($p) never gets a null pattern.
info: In the merge (scripts/lib/maintainer-comment-gate.sh:386), $t holds only string author types. The API value is on the right of +, so it overrides anything already in the snapshot. A null GraphQL author stays untyped, and an id that GraphQL did not return keeps no type. If the lookup fails, the snapshot comes back unchanged, so a clean notice blocks.
info: The untyped-author warning is guarded: its jq call falls back to 0, and the count must match ^[0-9]+$. A bad registry value cannot break the gate.
Follow-ups (do not block)
minor: The QA-lead advisory suggested two tests that are still missing:
a failure-path test: gh exits non-zero, the snapshot comes back unchanged, and the notice blocks;
a two-page pagination test for the __typename merge.
Both gaps can only cause extra blocking, never a bypass.
minor: The new warning also counts comments that are already minimized as RESOLVED or out of the gate's scope. dev-lead's maintainer_gate_open_comment_ids path has no matching warning. This only affects diagnostics.
minor: The Sonar exemption now depends on SonarQube Cloud's v2/checks/QualityGateBadge/qg-passed-20px.png URL. If the vendor changes it, clean notices will block again until the registry is updated. The PR's monitoring section names the log lines to watch.
minor: Possibly dead code. In check_maintainer_comments, the $lbare binding (scripts/lib/maintainer-comment-gate.sh:182) may now be unused, because info_status_clear computes its own. The diff cuts off the rest of that filter, so I could not confirm this.
info, out of scope: Codex's clean "Code Review Summary" comment (has_any_findings:false) does not match its registered pattern, so dev-lead had to disposition it by hand on this PR. This PR did not cause that. It could be a separate registry follow-up.
Security and supply chain
info: No workflows, actions, dependencies or secrets are changed. The safety checks found no CI weakening, no prompt injection and no secret forwarding. gitleaks, CodeQL, AgentShield and the Agent Security Scan passed. This PR's own SonarQube Cloud comment opens with the exact badge prefix the new pattern requires.
info: Downstream: 8 consumer repos pick this library up through dev-lead-reusable.yml and pr-review.yml. Rollout goes through canary promotion, and the description gives the channel-rollback steps.
Not verified
The MCP secret-scanning tool was not available, so I skipped that scan. gitleaks passed.
I had no shell or network access. I could not run shellcheck or bats, read scripts/, CODEOWNERS or feature-ideation.yml, or check whether the gate accepts the dev-lead dispositions as verified. For the code checks I relied on the CI results above.
The pre-fed metadata does not include review-thread resolution state. No review requested changes. CodeRabbit's one nitpick, the shim guard on the query, was applied. The only human comments are review requests and the QA-lead advisory, which says "Escalate? no".

…f PRs (#2468)
* fix(comment-gate): no-finding bot summaries keep approval on hands-off PRs
Codex and CodeRabbit edit one summary comment on every push. Under #2008
each edit needed a fresh dev-lead disposition, and on a dev-lead:hands-off
PR dev-lead writes none, so pr-review approved and then dismissed its own
approval (#2456, #2467).
A Codex or CodeRabbit summary whose bot reports, in its own structured
state, that the review found nothing now needs no disposition:
- Codex: one codex-review-state:v1 JSON, code review completed with
has_any_findings and has_unresolved_findings false, security review
never run or completed the same way.
- CodeRabbit: one final_review_risk_label reading Merge Risk "Minimal",
one final_review_risk_coverage with kind "reviewed", and only "passed"
pre-merge check badges.
The author must be the GitHub App and the body must carry no
finding-bearing section. Any other state still blocks. SonarCloud's
passed notice already cleared via its info_status_pattern.
The same predicate filters dev-lead's candidate list, the #2008 re-open
and stale-disposition lists and the bot-comment retry, so nothing
re-opens, chases or retries a summary the gate clears. ADR-0012 gains
exemption 6.

* fix(comment-gate): fail closed on partial Codex security state; skip re-verify
Review follow-ups on the no-finding summary exemption:
- A Codex security_review now clears only as an object carrying all four
fields: all null (never ran), or completed with no findings for the SAME
40-hex commit as the code review. A null, empty, partial, other-commit
or invalid-SHA security review still blocks.
- dev-lead's resolver no longer puts a no-finding summary on its
re-verify list (new maintainer_gate_no_finding_ids), so it is never
unminimized for lack of a straddling disposition.
- Tests cover RESOLVED Codex and CodeRabbit summaries edited after their
disposition: not re-opened or chased, while the same summaries with
findings still are.

Problem
The maintainer comment gate lets a registered bot's no-finding notice through with no disposition (#1918, #1995). Two examples are SonarQube Cloud's "Quality Gate passed" summary and Codex's usage-limit notice. The gate tied that exemption to the bare login only. It never checked that the author was the bot.
GitHub has an ordinary User account named
sonarqubecloud. That account could post the passed-gate text on any PR and clear the gate. The Sonar pattern was also unanchored, so it could match the passed-gate text anywhere in a body.Note on combsmith/.github#1421
I replayed the gate against the live #1421 comments at the channel commit that dismissed the approval (
cd02e25, run 41829975366). Both notices were already exempt, minimized or not:IC_kwDORyesfc8AAAABipnEHw(Sonar)IC_kwDORyesfc8AAAABgQo7fQ(Codex)The blocker I can reproduce is CodeRabbit's summary

That makes a stall on clean notices easy to diagnose.scripts/lib/reviewer-sources.tsv: thesonarqubecloudpattern is now anchored to the passed-badge prefix every SonarQube Cloud gate comment opens with. I checked 43 Sonar comments across 40 org PRs, and all start with it. The zero-issue and zero-hotspot requirements are unchanged. The Codex pattern was already anchored at the body start.tests/test_feature_ideation.bats(separate commit): fixes a stale test that has failed onmainsince fix(feature-ideation): re-dispatch only for authors with write access #2444. fix(feature-ideation): re-dispatch only for authors with write access #2444 switched the feature-ideation redispatch job toGH_TOKEN: ${{ github.token }}, which can startworkflow_dispatchruns, andGH_PAT_WORKFLOWSis being retired (chore(secrets): retire GH_PAT_WORKFLOWS + GH_PAT after don-petry PAT cutover (manual/gated cleanup) #1326). The test still requiredsecrets.GH_PAT_WORKFLOWS. It now asserts that the redispatch job usesgithub.tokenand that the workflow no longer referencesGH_PAT_WORKFLOWS.No other exemption path changes.
maintainer-resolve-comment.shalready required aBotactor for its bot path.Call sites
Both callers already supply the author type:
scripts/review-one-pr.shmaintainer_gate_merge_edit_times, which now selectsauthor{__typename}ghshim now answers only a query that selectsauthor{__typename}, so dropping it fails the test.scripts/dev-lead-fix-reviews.sh(resolve_dispositioned_comments)author{login __typename}Risk
The risk is medium. Every change makes the gate stricter, and every failure mode fails closed.
The worst case is that clean Sonar or Codex notices block again on a PR. That would happen if the author-type lookup fails, or if a vendor changes its badge URL. The fix then is the old manual step: minimize the notice as RESOLVED, or add
<!-- maintainer:not-a-finding -->. No path clears a comment it did not clear before.This library reaches consumers through the dev-lead and pr-review reusables.
