  # Single-container default (HEALTHLOG_PROCESS_TYPE=all). Existing

  app:
    # Tracks the GHCR `:latest` multi-arch image. `pull_policy: always`
    # is the load-bearing line — without it, Docker keeps a stale
    # `:latest` digest cached on the host and skips the registry round-
    # trip on `compose up`, which is what kept Coolify re-deploying the
    # previous image after every tag push. With pull_policy=always the
    # compose-up always re-checks the registry digest and pulls when
    # GHCR has a fresher manifest. The small bandwidth cost on every
    # `compose up` is the price of digest-correctness.
