# ORCH-058 (Strategy B): stamp the image with the git commit it was built from so
# the deploy hook can fail-close if a stale staging image would be promoted to prod
# (INV-FRESH). Passed at build time via `--build-arg GIT_SHA=<sha>` (the staging
# rebuild in check_staging_image_fresh / the --build-staging hook mode supplies it).
# Without the build-arg the label is empty -> the hook treats it as a mismatch
# (fail-closed). The OCI-standard key is read by `docker image inspect`.

# ORCH-021: do NOT `COPY data/ ./data/`. `data/` is gitignored (SQLite DB dir) and
# is provided at runtime as a bind-mount volume (`./data:/app/data`, see
# docker-compose.yml) which shadows anything baked into the image — so the COPY was
# dead weight. Worse, the ORCH-058 staging rebuild (`check_staging_image_fresh`)
# builds with the task *worktree* as the docker build context; a fresh worktree never
# contains the untracked `data/`, so `COPY data/` failed `docker build` with exit 1
# and bounced the task off `deploy-staging`. We just ensure the mountpoint exists.
