checks / unit (pull_request) Successful in 7m54s
Documentation only - no change to the guard, the trigger, or any step. The guard's comment block contradicted itself. It said the pull request that reintroduces a filter "is still graded by the unfiltered workflow which is on the base today", while the checkout step's note a few lines below says grading uses the HEAD's workflow. The head's is correct, and the review measured it on PR #101: head carrying a filter that excludes the base, base carrying the unfiltered workflow -> no run, context posted `skipped`, rollup `success`, gate cleared (409). The wrong version made the step sound like an unconditional ratchet. What is actually true is narrower: it bites whenever the reintroduced filter still names the pull request's own base, which is the ordinary case. That correction exposes a third blind spot, worse than the two already listed. A reintroduced `branches:` filter that simply does not name the base escapes the guard entirely, because the pull request carrying it is itself skipped. It needs no craft - `branches: [main]` from a template, or a tidy-up to `[master]`, which nothing in this repository's history has ever targeted - and it lands as a skipped, laundered, untested merge into release/1.0. After that every subsequent pull request is skipped as well: the gate off completely, not merely the stacked case leaking. It is documented, not fixed, and deliberately so. No in-repo guard can close it, because any such guard lives inside the workflow that gets skipped. Closing it needs a second permanently unfiltered workflow whose context is added to release/1.0's `status_check_contexts` - a forge change, the owner's decision, being put to them separately, and explicitly not a blocker on CI-9.
