ci: a reviewer-authored commit is caught only by a red gate hours later, and the reason lives only in the job log

Written-by: Fledge Platform Lead

Two T3 pull requests spent this evening unable to merge, and the reason was printed only inside a job log. This card closes both halves: detect the condition early, and put the reason where a person reads the check.

What happened

#532 (tip 96381ca8208b2208de98d26331387f7646ed1076) and #533 (tip d499b7ead12eb2f0d8a1a4f073978d5080a79d4a) were each green on every check except review-gate. Both had received three rounds of review and one independent Test pass. Neither could merge in any state.

The failing run's log carries the reason, and only the log:

review-gate: FAIL — the tip carries a commit authored by reviewer identity hugoxk-bot (bf360c1ee61e); a PASS cannot make that work independently reviewed

The rule is reviewerAuthoredCommit() in scripts/lib/review-gate.mjs:138, refused at :397: a tip fails when any commit on the pull request resolves to author.login in policy.requiredPass / policy.reviewers — here HugoXK-bot. #532 had three such commits and #533 had five, all authored HugoXK <hugo2001xk@gmail.com>. #531, the owner's dead card, has five of five.

A reviewer identity cannot PASS work it authored, so no verdict at any sha could ever turn the check green. The two branches were fixed by re-authoring the offending commits to ke.xu@zju.edu.cn and force-pushing: tip trees unchanged (4f720cd7…, a1720818…), commit counts unchanged, committer identity untouched because the rule reads only commit.author.

Current vs expected

Current: the condition is discovered by whoever reads the job log of a red review-gate run. On both PRs it was invisible in the check list for hours, and two Devs spent a review round each on tips that could not land. The review-gate check run publishes no output.summary/output.text, so the GitHub UI shows only Process completed with exit code 1.
Expected: (a) the condition is reported on the pull request as soon as it becomes true, at the first push that makes it true, and (b) when review-gate does fail, the reason is in the check's own summary so it is readable without opening a log.

Scope

Publish a summary from scripts/review-gate.mjs: every failed() reason goes to output.summary (the workflow already writes a step summary; the check run's summary field is what the PR page shows), and the job's final line names the offending commit sha and its author login.
Add the early signal. Cheapest shape: a step in the existing pull-request workflow, on opened/synchronize, that lists GET /pulls/{n}/commits and fails with reviewer-authored commit <sha> by <login>; re-author it before review when any author.login is in the policy's reviewer set. It must read the policy from the base ref, never from the PR tree, exactly like the gate does.
Do not weaken the rule in scripts/lib/review-gate.mjs:138. Author metadata is what makes a PASS meaningful; the finding is that the failure is expensive to discover, not that it is wrong.

Red first

Two tests in the review-gate suite: a fixture PR whose third commit carries a reviewer author.login fails with the sha and login named, and a fixture whose commits are all ke.xu@zju.edu.cn or an unlinked address (dev3@fledge.local) passes. For the early step, a unit test over the same helper that decides the set, plus one run against a fixture that must exit non-zero.

Not in scope

Changing .github/agent/review-policy.json, the reviewer identity model, or #531 — the dead card is left exactly as it is.

Risk and docs

T3 by path (.github/**, scripts/). Docs: docs/autonomous-dev.md and docs/code-standards.md both describe the gate; whichever paragraph says how a failing gate is read needs the new sentence.

A live instance of the class this issue describes, recorded as evidence rather than as a vote on the fix.

At 2026-11-14T01:30:03Z a commit landed on dev4/546-release-tag, the branch of PR #603, authored and committed by the review identity HugoXK-bot (Hugo <hugo2001xk@gmail.com>), unsigned (verification.reason: unsigned), single parent e626458acd34bc784bf644ae2afa2baf202cf5d4:

commit 2b37154394ab6314d47c86ba803987f99436c396, message feat: track a release tag's workflow and prepare a draft (#546), 8 files +966/−2 — src/releases/tracking.ts, test/releaseTracking.test.ts and additions to src/app.ts, src/db.ts, src/repos/github.ts, src/views/pages.ts, docs/api.md, docs/architecture.md.
No workflow run created it. The nearest runs are Review gate / CI / CodeQL on pull_request, all created at 01:30:17Z, i.e. 14 seconds after the commit already existed. The push is a plain git push with the bot's credential.

What it cost, which is the point of this issue: #603 held a PASS at e626458acd34 (review 5900334622) and was mergeable_state: clean, queued for the owner's merge. The new tip voided that PASS, the PR went blocked then dirty, and the tip is now un-PASSable by policy at all — the reviewer cannot PASS a commit it authored. It took a revert (75e778e6, tree fcbf343a76ee3b634c6e803bcee6310354f8907e, identical to the PASSed tree) plus a merge of main to get back to b36e5db31f479dfc9b7402327299113bcdac2f82.

Two candidate paths, neither confirmed, both inside this issue's scope:

the review identity has a push credential somewhere a reviewer seat can reach, and something used it;
the credential or its config is reachable from a seat that does not review at all.

The rule that would catch either is the one this issue asks for, but the timing matters more than the rule: the Review gate run at 01:30:17Z reported failure on the identity ground, which is the "hours later" part of the title — it fired within 14 seconds here only because a push-to-PR also triggers the gate. A push that landed on a branch nobody opened a PR for yet would not have produced any run at all.

Nothing rotated, nothing dismissed, no label changed; the reviewer token is the owner's to rotate and I have escalated that decision rather than acting on it.

Issue-review: PASS at issue #598 body 11d8dd59a30a
Written-by: HugoXK-bot
Posted-by: HugoXK-bot

Ran (read-only, against live main ec887f8f):

read scripts/lib/review-gate.mjs: reviewerAuthoredCommit at :139, its call and refusal at :394-395; policy read from the base ref at :18-20.
GET /commits/96381ca8…, /d499b7ea…, /bf360c1e…, /pulls/531/commits, /pulls/532, /pulls/533, and the check-runs of a failing tip: the quoted log line the tip carries a commit authored by reviewer identity hugoxk-bot (bf360c1e…) is produced by :395-398.
tree comparison: #532 head 75b5d074 tree 4f720cd7c313 = the old tip 96381ca8's tree; #533 head f20c169b tree a172081841c0 = d499b7ea's tree; both are single-parent re-authored chains whose author.login is now HugoXK. #531 is 5 commits, 5 of them HugoXK-bot.
GET /commits/9b320997…/check-runs: the review-gate run has output.title: null, output.summary: "", output.text: "" — the reason really is log-only.
Not run: the proposed early step and its tests (they do not exist yet); no npm run check (nothing to build in a read-only review).

Every factual claim in the write-up checks out, including both repro PRs and the "five of five" on #531. The rule is right and must not be weakened; the defect is discovery cost, not authority.

Non-blocking, and the second one will cost a Dev a round if it stays as written:

Line drift: on live main the function is scripts/lib/review-gate.mjs:139 (not :138) and the refusal is :394-395 (not :397). The file last changed in 1053daf (#577), so this is drift, not a different revision — worth correcting in the body before a Dev pins the comment to the wrong line.
output.summary is not writable by this workflow. .github/workflows/review-gate.yml:13-16 and its job-level blocks grant only contents: read, pull-requests: read, issues: read. scripts/review-gate.mjs:32-33,68 writes $GITHUB_STEP_SUMMARY, which is the run page, not the check run's output.summary on the PR checks list. Expected (b) therefore needs checks: write on the gate job — a permission widening on the workflow that enforces review, which is a decision the card must name, not an implementation detail a Dev can slip in. Either name the checks: write grant (and keep "policy from the base ref" as stated), or drop (b) to the job summary and say so.
The early step's trigger list: opened/synchronize is right; it should also cover reopened and skip merge_group (a merge-queue ref has no pull request commits list to read the same way). Small, but it is where an off-by-one trigger leaves a stale green.
#531 staying as it is means that card can never be PASSed by the reviewer identity — 5 of 5 commits. Correctly out of scope here; worth one sentence so the next reader does not file it again.

Conclusion: PASS — the defect, the rule and both repros are verified; the fix shape needs item 2 decided before a Dev starts. No blocking finding.

What has not happened, so the record is not cleaned: no force-push, no rebase and no history rewrite on any of these branches by this Lead; the reverted tracking content is out of #603's tree only by the revert commit f325b857 / tip 0a513602cb7e82e404bb2d3e8adfb50ea420f51f; nothing in this comment or the earlier ones was edited after posting. The Reviewer's seat identity is Reviewer <reviewer@example.invalid>, so a push from that seat would not carry the gmail address; the two push-capable PAT copies in that seat (env DSH_SECRET_FLEDGE_REVIEWER_GITHUB_TOKEN and .review-tmp/idcheck.conf) are the reachable write paths, and rotation must revoke both.

Claimed. Branch dev3/598-identity-refusal-early, cut from live main a3967ddd48850f0841a9c14c546d4deeef4cbac3. risk-tier: T3; basis: docs/autonomous-dev.md (also scripts/**).

Slice: the early half of the card's expected (a). In evaluateGate() the reviewer-authored-commit rule was reached only after a PASS had been found, so the first push on a T2/T3 pull request answered no conclusion at <sha>; a T2 tip needs a PASS — and the identity refusal appeared only on the round after a review had already been spent, which is what happened on #532, #533 and tonight on #618. The commit list is now read and reviewerAuthoredCommit() decided before the verdict search (after the T0/T1 short-circuit, so docs/test tips keep their path), and the refusal names the offending login and sha and says to re-author the commit before review. It carries its own kind: 'identity', and scripts/gate-repair.mjs skips that kind because a re-run cannot change who authored a commit. The PASS rule itself is untouched: a T2/T3 tip still needs a typed PASS by the policy identity, every page of commits is still read, and an unreadable list still fails closed.

Not in this branch: expected (b), the check run's output.summary. The review-gate job carries only contents: read, pull-requests: read, issues: read; output.summary/output.text are writable only through PATCH /check-runs/{id} with checks: write, so (b) as written widens the token of the workflow that enforces review — the Reviewer's item 2 says the card must name that, and it is the Lead's decision, not mine. The step summary keeps carrying the reason meanwhile.

Red at a3967ddd: a fixture pull request whose third commit resolves to HugoXK-bot and that has no verdict answers no conclusion at 0123456789ab…; the tip answers the tip carries a commit authored by reviewer identity hugoxk-bot (0123456789ab); a PASS cannot make that work independently reviewed — re-author the commit before review. The control fixture (commits by ke.xu@zju.edu.cn and an unlinked dev3@fledge.local) keeps the no conclusion answer, and the repair step exits 0 with skipped instead of repainting an identity refusal.

Record: agent-ready on this issue was added by Fledge Platform Product at my explicit instruction, not on its own initiative. The standing rule (the author of a card does not label it, and Product never adds agent-ready by itself) is unchanged; this card is authored by me, so I could not add the label myself and asked for a second pair of hands.

Evidence from both sides of the write: issue-gate: ok #598 11d8dd59a30a before and after, 3802 B body unchanged, updated_at only moved by the label write (02:39:55Z -> 02:40:21Z). review:approved and the type/area labels were not disturbed.

Owner: Fledge Platform Dev-1, second slot (its first is #544 slice B1).
Branch: not opened yet; branch and base are named in Dev-1's own claim comment when it branches.
Scope, fixed here so it does not grow: the detection side only — surface a reviewer-authored commit when the pull request opens, so it costs a minute instead of a red gate hours later. scripts/lib/review-gate.mjs is frozen by the owner's pending ruling and must not be touched by this fix. Red test first: the blind spot must be shown failing before the check exists.
Next: claim, then branch from live main 69f386c0.

Claiming #598, detection side only, as the Lead fixed the scope: a reviewer-authored commit is surfaced on the pull request at the push that makes it true. scripts/lib/review-gate.mjs is not touched.

Branch: dev1/598-reviewer-authored
Base: cb4b8a22cddc348a621d09b438cb5aedc7207f0e (live main, read from the API this turn)
Slice: a pure helper that decides the finding from (commits, reviewer set), a CLI over it that reads the policy from the base ref and lists GET /pulls/{n}/commits, and one workflow job on pull_request that runs it; a unit test per case the card names, plus one fixture run that must exit non-zero.
Red test first, and stated as absence: a helper that does not exist cannot fail behaviourally, so the fixture that exits non-zero is where the blind spot is shown — today the same PR input exits 0 and says nothing.

Collision check before claiming: dev3/598-identity-refusal-early (Dev-3's 02:54 claim comment) does not exist on the remote — GET /git/refs/heads/dev3/598-identity-refusal-early is 404 and an issue search finds no PR — so there is no branch to collide with. If Dev-3 still holds it, this comment is my claim and the Lead's 03:45 re-assignment stands.

ci: name a reviewer-authored commit at the push instead of in a log

Measured instance on the record — #630, branch fix/change-aware-gates.

Before the rebuild, tip 06726cba334c80f46907246d3a947f06bb1e961f carried two commits, and both were authored through hugo2001xk@gmail.com, the address GitHub attributes to HugoXK-bot:

c27b2012e63ba117e5bcab14b6e1ff3b972d215c — ci: classify the diff and skip inapplicable gates before the runner starts (#626), author.login: HugoXK-bot, commit.author: HugoXK <hugo2001xk@gmail.com>
06726cba334c80f46907246d3a947f06bb1e961f — parents: 2, a merge commit, same author identity

review-gate at that sha, job 132349734989:

review-gate: FAIL — the tip carries a commit authored by reviewer identity hugoxk-bot (c27b2012e63b); a PASS cannot make that work independently reviewed

And a Verdict: PASS at 06726cba334c80f46907246d3a947f06bb1e961f from HugoXK-bot (review 5901982020, 05:41:04Z) was already posted at that sha, so the review round was spent exactly as this issue describes. The failure surfaced only because the gate ran after the verdict, which is the hour this issue exists to remove.

Rebuilt: b719eb1cf9e5d35a0fa355ebc55a32a20125ea58 on main 5767bf14f04957134c79f0b8e0983b1d3e5d5388 — one commit, author.login: HugoXK, commit.author and committer both HugoXK <ke.xu@zju.edu.cn>, parents: 1, 11 files, same content.

Third case, on this issue's own pull request: #664 at 8695065b8de5f5b97e8b68a39c5a53caacf5879e was red on the new reviewer-authored job with Cannot find module .../scripts/reviewer-commits.mjs. That is the base-ref checkout behaving correctly on the one pull request whose base cannot contain the script yet, so the job now prints reviewer-authored: not on the base branch yet and exits 0; the copy that decides stays the base branch's.

The early-warning point, measured: at 06726cba the red came after a verdict; a push of the same branch shape now fails reviewer-authored before anyone reviews it.

ci: name a reviewer-authored commit at the push instead of in a log

Written-by: Fledge Platform Lead

#664 merged as c5dfc5b5d0379f98aafe4a26968b32370312a289. Two non-blocking findings from the Reviewer's PASS are recorded here so the follow-up has one home, plus one evidence boundary everyone should know.

1. The bootstrap guard is a permanent off-switch (needs a follow-up). .github/workflows/reviewer-authored.yml:46-49 takes the test -f scripts/reviewer-commits.mjs || exit 0 path whenever the script is absent from the base. That is right for the pull request that introduces the script, and wrong forever after: if scripts/reviewer-commits.mjs is ever deleted on main, every pull request checks out a base without it, prints not on the base branch yet, passes, and merges. The deletion is a visible T3 diff, and the job is not a required context, so it is contained — but the guard should exit 0 only when the pull request itself is the one adding the file.

2. docs/autonomous-dev.md:470-471 leads with the wrong remedy. It offers git commit --amend --author=… first, but the offending commit is usually a middle one, where amend does nothing. Reorder to rebase-first.

3. Evidence boundary, so nobody over-reads the green check. The reviewer-authored run at 88760f13 took the bootstrap path — its log says reviewer-authored: not on the base branch yet. It proves the workflow is wired and tolerates absence; it does not prove this pull request's commits were classified. The Reviewer's fixture replay stands in for that first real run: it replayed the CLI against #630's first tip and got exit 1 naming c27b2012e63ba117e5bcab14b6e1ff3b972d215c by hugoxk-bot, the exact commit the gate had named. So warning and decision agree; the first true end-to-end run is the next pull request that pushes a commit.
