The worker checks out main, serializes runs by issue, creates signed branches, and does not create or merge pull requests automatically. Retain the existing advisory Claude PR reviewer rather than adding a duplicate. Verification: actionlint .github/workflows/claude.yml; git diff --check; local command-gate regex cases.
