+  contexts, where a path-filtered workflow leaves its context Pending forever. Measured from
+  `branches/main/protection` on 2026-09-06, that list is these 12: `CodeQL compatibility analysis
+  (actions)`, `CodeQL compatibility analysis (python)`, `Detect CodeQL languages`,
+  `coverage-evidence`, `dependency-review`, `noema-review`, `opencode-review`, `osv-scan`,
+  `required-workflow-bootstrap`, `scan-pr-queue`, `scorecard`, `trivy-fs`. Re-read the endpoint
+  rather than trusting this list: branch-protection edits leave no trace in git, so a stale list

+  correction of an unverifiable count, **not** evidence that two contexts were removed. Never add a
+  trigger-level filter to a required workflow; skip at job level via a `changed-scope` gate job
+  instead, and always keep one job with no output-dependent `if:` so the run concludes `success`
