The PR Gate workflow's only job, size-check, labeled every PR with
size/S–size/XL based on lines changed. Those labels aren't used in any
review, triage, or automation flow, so the workflow was pure noise.
- Delete .github/workflows/pr-gate.yml
- Drop size-check from required status checks in both rulesets so PRs
don't block forever on a check that never reports
- Remove pr-gate.yml from INERT_WORKFLOWS (ci-test-scope.cjs) and the
knownInert list (ci-test-scope.test.cjs)
- Remove "PR Gate / size-check" from setup-branch-protection.sh
Closes#846
