# Auto-deploy arbo CATALOG on a verified main push (run by the webhook listener).
# Restart the engine ONLY when catalog/ changes (loaded once at startup -> app.state.cat).
# graphs/ + frontend/ are read PER-REQUEST (no restart). A NEW IMAGE (not a restart) is
# needed only for src/ or Dockerfile changes. NOTE: pyproject.toml + uv.lock churn on
# EVERY commit (per-commit SemVer version bump) so they are NOT image signals -> ignored.
# Confirmed against engine code w/ comfy-dev 2026-06-13.
