# them to the LAN endpoint (192.168.0.2:1234). For local building instead of
# pulling, layer the dev override:
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d --build

  # One-shot schema migration: runs `alembic upgrade head` and exits. Backend
  # and worker wait for it to finish, so on `docker compose up` the schema is
  # always current before the app serves traffic — no manual migrate step.
  # NOTE: a pure Watchtower image-swap recreates only the long-running
  # containers, not this one-shot job, so Watchtower deploys should be paired
  # with a `compose up` (see deploy docs) to re-run migrations.

    # No per-setting allow-list to maintain, so a new setting in .env (and
    # .env.example) reaches the app with no compose edit. The `environment:`
    # block below is only for values that must NOT come from .env:
    #   - RUN_MIGRATIONS: backend-only flag, not an app setting.
    #   - DATABASE_URL: pinned to the compose-internal host as a safety net —
    #     the code default points at localhost, which is wrong inside the
    #     network. (.env normally sets it; this guards against it being absent.)
    # `environment:` wins over `env_file`, so these always take effect.

    # MINIO_*, CLOUDFLARE_TUNNEL_TOKEN) to the app process; the app ignores them.
