Dogfood — Gatekeep reviews Gatekeep

The Action repo itself runs Gatekeep on its own pull requests.

Piece	Path / value
Live workflow	.github/workflows/gatekeep-pr.yml
Action	uses: ./ (repo-root action.yml)
Secret	OPENROUTER_API_KEY → step env
Trigger	pull_request (non-draft) + workflow_dispatch
Proven	PR #2 got <!-- gatekeep-review -->; run 15833 success

Gitea notes: no actions/setup-node mirror — Action requires runner Node ≥18. PyYAML installs via workspace venv (PEP 668). Free OpenRouter models may 429; review still posts (fail-closed tier).

How to see a review

1. Branch off main, make a tiny change, open a PR on https://git.potatolab.uk/layue13/gatekeep
2. Wait for the Gatekeep workflow (same Actions runner pool as other layue13 repos)
3. Look for the summary comment <!-- gatekeep-review --> on the PR

Consumer sample workflows remain under top-level workflows/ for copy-paste into other repos’ .github/workflows/.
