name: beta (rc) bakery

# Publishes a beta-track build for any `vX.Y.Z-rc.N` prerelease tag pushed
# to `main` — there is no separate `beta` branch; "freezing" is just
# pausing pushes to main while an RC gets tested. See
# docs/release-channels.md for the release-track policy.
on:
  push:
    tags: ['v*']
    # No paths: filter. Tag pushes compare against an unrelated commit and
    # would skip the RC publish if bakery/** wasn't in that diff; the job
    # `if: contains -rc.` is the real gate.
