# WHY: waiver keys off the PR author login, not github.actor — actor flips
# to a maintainer login on "Re-run failed jobs", re-arming the check on bot PRs.
# Release-please is ALSO waived branch-shaped: under GITHUB_TOKEN its PRs
# are authored as github-actions[bot] (and as the PAT owner once a PAT is
# wired) — the author varies, the branch pattern does not. Release-PR
# content is generated version bumps; its verification is the live
# deny/audit/osv checks.
