fix: spec - correct a false claim about the shipped changelog gate - #3583
Conversation
Spec 016 FR-009 asserted that the shipped gate exempts a pull request changing only CHANGELOG.md, because its docs-only test accepts any file ending in .md and CHANGELOG.md ends in .md. That claim is wrong, and it reached the specification through my own review of #3500, where I read one line of the gate's require step rather than its control flow. The gate tests changed.includes("CHANGELOG.md") and returns run_validation=true before the docs-only exemption is ever evaluated, so a changelog-only pull request is validated. Verified three ways: the guard appears at character 4246 and the docs-only test at 5368 in the workflow, so the guard is reached first; the full require-gate suite passes 41 of 41; and it already contains "runs validation when the root changelog changed", which asserts exactly this and contradicts the claim, alongside "exempts a nested CHANGELOG.md under docs/ as docs-only", which is the case the .md suffix really does cover. No gate change is needed, so none is made. FR-009 now states the gate's actual order of tests, notes that the ordering is what keeps FR-008 and FR-009 consistent rather than conflicting, distinguishes a root CHANGELOG.md from one nested under docs/, and cites the tests that pin the behaviour. FR-008's cross-reference to a non-existent conflict is removed, the constraint line states the full shipped order, and the same correction is applied to FEEDBACK_RESPONSE.md, which repeated the claim on develop.

- Around line 100-101: Update FR-008 in the changelog validation specification
to limit validation to pull requests that reach the gate’s changed-file check,
explicitly accounting for the Dependabot and docs-bot author exemptions in
FR-009. In FEEDBACK_RESPONSE.md, update the corresponding root-changelog
statement to say that a root CHANGELOG.md change triggers validation only after
those author exemptions.

CodeRabbit is right that FR-008 and the corrected FR-009 were incomplete. The
gate skips Dependabot and docs-bot authors before it inspects any file, so those
pull requests never reach the changed.includes("CHANGELOG.md") guard and are not
validated even when they modify the root CHANGELOG.md.
Verified against the workflow: the dependabot skip is at character 430, the
docs-bot skip at 931, and the CHANGELOG.md guard at 2304, so the author skips
unambiguously come first.
FR-008 now carries the exception and FR-009 states that the ordering means the
guard applies only to pull requests that reach the file inspection.

Qodo's local review caught a second completeness gap in the same area CodeRabbit flagged. FR-008's exception, FR-009's bypass list and the shipped-gate constraint all named only Dependabot and docs-bot, but changelog-unified.yml skips the require-gate job outright when github.actor is imgbot[bot] -- a job-level if: on line 30, not an in-script author check. So an image bot's pull requests are exempt from the changelog requirement too. All three now say so, and distinguish the job-level skip from the in-script author checks, since they happen at different points. Its other finding, on .github/reports/changelog-metrics/20260926.json, is a generated artefact left in the worktree by a test run: the file is untracked and the pull request diff contains no report files, so it is not part of this change. Also merges origin/develop for #3495, which touches none of these files.

Context
Reproduction
FR-009in.github/specs/016-changelog-agent-quality/spec.mdondevelop.file.startsWith('docs/') || file.endsWith('.md').CHANGELOG.mdends in.md, so a pull request changing onlyCHANGELOG.md"is therefore exempt from the changelog requirement", described as "a defect in the shipped gate"..github/workflows/changelog-unified.ymlfrom the top of its require step.Root Cause
The gate's require step evaluates its tests in this order:
meta:needs-changelogandmeta:no-changelog, ormeta:no-changelogon a high-impact release type — failchanged.includes("CHANGELOG.md")— setrun_validation = trueand returnfile.startsWith("docs/") || file.endsWith(".md")) — skipmeta:no-changelog— skipA changelog-only pull request returns at step 3 and never reaches step 4. The
.mdsuffix only determines behaviour for aCHANGELOG.mdnested somewhere other than the repository root, which is correctly treated as docs-only.The claim was introduced during review of #3500 by reading a single line of the step with a text search rather than reading the step's control flow. It then survived several further review rounds, including a local CodeRabbit CLI pass, because it was internally consistent and plausible.
Evidence, checked rather than assumed:
runs validation when the root changelog changed, which assertsrun_validation === 'true'for a diff includingCHANGELOG.md— directly contradicting the claim — alongsideexempts a nested CHANGELOG.md under docs/ as docs-only, which is the case the suffix really does cover.Fix Summary
No workflow change: the gate is correct, so none is made.
FR-009now states the gate's actual order of tests, explains that the ordering is what keepsFR-008andFR-009consistent rather than conflicting, distinguishes a rootCHANGELOG.mdfrom a nested one, and cites the tests that pin the behaviour.FR-008's cross-reference to a non-existent conflict is removed, the constraint line states the full shipped order, andFEEDBACK_RESPONSE.mdcarries the same correction.Verification
CHANGELOG.mdonly andCHANGELOG.md+ code both return "RUN VALIDATION" via the step-3 guard;docs/guide.mdonly,README.mdonly, code withmeta:no-changelog, and Dependabot all skip; code only fails.scripts/workflows/changelog/__tests__/changelog-unified.test.js41/41 passing.Risk & Rollback
The real risk this removes: a reviewer trusting the specification would have "fixed" a working gate, and that fix would have contradicted two existing tests.
