name: Checksums drift

# Periodically re-fetch hooks/*/checksums.txt against the currently-pinned
# upstream versions. If anything changes, upstream rebuilt the release asset
# under the same tag (oxc-project does this occasionally), and our hooks
# would start failing with "sha256 mismatch" until someone manually re-runs
# scripts/fetch_checksums.py. This workflow catches drift automatically and
# opens a PR.

            chore: refresh upstream checksums

            Upstream rebuilt one or more release assets under their existing
            tag. Refresh hooks/*/checksums.txt so hook sha256 verification
            keeps matching what the GitHub release CDN currently serves.
          branch: chore/refresh-checksums
          delete-branch: true
          title: "chore: refresh upstream checksums (drift detected)"
          body: |
            Detected drift between `hooks/*/checksums.txt` and the sha256
            of the assets currently served by upstream. This happens when
            an upstream project rebuilds a release asset under its existing
            tag (oxc-project does this from time to time).

            Without this refresh, every consumer would see `sha256 mismatch`
            errors when prek/pre-commit runs the affected hook.
