feat(pr-validation): publish the gate verdict under one stable check name - #949
Conversation
…name A reusable workflow's check is reported as `<caller job> / ... / <job>`, and the caller's job name lives in the consumer's own repository. Measured across the 68 repositories consuming the umbrellas, the same gate produces six distinct names: 48 validate / PR Metadata / Breaking Change Approval / Breaking Change Approval 18 validate / Breaking Change Approval / Breaking Change Approval 5 ui / PR Metadata / ... 1 validate_mcp / PR Metadata / ... 1 Validate PR / ... 1 Metadata Validation / ... Required status checks match the context exactly, with no wildcard, so no single organisation ruleset can require the gate - and a required check that never arrives leaves the pull request pending forever, so listing all six would block every repository that produces only one. A commit status carries no job path. It is the reason `CodeRabbit` and `Socket Security` read identically everywhere, and it removes the caller from the name: set `BREAKING_APPROVAL_STATUS_CONTEXT` once and one rule covers every repository. Published on every run, including the ones with nothing to approve - out of scope, no breaking commits, superseded all publish success. A status that appears only sometimes cannot be required. `result` decides pass or fail; the state only chooses the wording, and the two are not allowed to disagree. `statuses: write` is deliberately not declared on the job: a called workflow may only ask for permissions the caller already holds, so declaring it would break every consumer that does not grant it - the same reasoning the file already applies to `actions: read`. It goes through MANAGE_TOKEN, and warns rather than failing when it cannot be written. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Sorry, something went wrong.
… dead one Three findings from CodeRabbit on #949, all valid. **A superseded run published failure over its replacement.** The verdict emits `state=superseded` with `result=failure` - confirmed by running it - so the authority line turned the intended success into a failure and published it. GitHub reads the latest status for a context, and a superseded run can finish after the one that replaced it, so this would block a pull request on a decision already given. Superseded now publishes nothing, the same rule the comment and the close already follow. My test could not see it: it passed the helper's default `result=success` for every state, which is not what the verdict emits for this one. Each state now carries its real result. **No pending status before the wait.** The previous run's success stayed current while this run sat at the Environment, so a rule requiring the status would allow the merge on a decision nobody had given. The head SHA does not have to change for that - `edited` re-runs on the same commit, and retargeting a pull request moves it in or out of scope. The status now goes pending in `request`, before `approval` can wait, and only when this run will actually hold. **The warning offered a remedy that does nothing.** It suggested granting `statuses: write` on the caller's job. The job declares its own `permissions:`, which replaces what the caller granted, so only MANAGE_TOKEN can write it. Corrected in the warning, the input description and the guide.

Two more from CodeRabbit on #949, both real. **An older run could publish success over a newer run's pending.** Retarget a pull request to an in-scope base without touching the head SHA: the old out-of-scope run keeps going - `concurrency` covers the approval job alone, not the workflow - reaches `state=none`, and publishes `success` after the new run has set `pending`. GitHub reads the latest status for a context, so a status-only rule would allow the merge before anyone decided. `superseded` does not cover it. The head did not move and nothing was cancelled, so the old run's `none` is a legitimate verdict about a scope that no longer applies. Both writers now read who wrote the context last and stop if that run is newer. The run id is already in the `target_url` this gate writes, so the ordering is readable without asking the runs API, and a status written by anything else has no id to compare and is left alone. **The doc's failure mode was wrong.** It said a rule requiring the status would stay pending if the write failed. That is only true for a commit with no status yet; where the SHA already carries `success` for the context, a failed write leaves that success current and the merge is allowed. Now stated, with the advice to require the gate's job alongside the status until a run has written it at least once. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Description
Prerequisite for requiring the breaking-change gate in an organisation ruleset.
A reusable workflow's check is reported as
<caller job> / … / <job>, and the caller's job name lives in the consumer's repository. Measured across the 68 repositories consuming the umbrellas, the same gate produces six distinct names:validate / PR Metadata / Breaking Change Approval / Breaking Change Approvalvalidate / Breaking Change Approval / Breaking Change Approvalui / PR Metadata / Breaking Change Approval / Breaking Change Approvalvalidate_mcp / PR Metadata / …Validate PR / …Metadata Validation / …Required status checks match the context exactly, with no wildcard. So no single ruleset can require the gate — and listing all six is worse than listing none, because a required check that never arrives leaves the pull request pending forever, and each repository produces only one of them.
What this adds
A commit status carries no job path. That is why
CodeRabbitandSocket Securityread identically in every repository, and it is the fix here:status_contextpublishes the verdict under a name the caller cannot change.One organisation ruleset requires
breaking-change-approval, and it covers every repository whatever its jobs are called. Renaming a job in a consumer no longer silently detaches it from the rule.Three decisions worth stating
Published on every run, including those with nothing to approve. Out of scope, no breaking commits, superseded — all publish
success. A status that only shows up sometimes cannot be required.resultdecides pass or fail, not the state. The state only chooses the wording, and the two are not allowed to disagree — one line enforces that, and a test fails when it is removed.statuses: writeis deliberately not declared on the job. A called workflow may only ask for permissions the caller already holds, so declaring it would break every consumer whose entrypoint does not grant it — the same reasoning this file already applies toactions: read, in a comment right above. It goes throughMANAGE_TOKENinstead, and when it cannot be written the step warns and carries on rather than failing the job over a check the caller may not even require. The warning names the missing permission, because a rule requiring the status would otherwise stay pending with no explanation.Requiring the job name still works for a single repository, and this one keeps doing exactly that. The status is for when one rule has to cover more than one repository.
