# Coordinator container — runs the Pipeline A review loop.
#
# Design:
#   - Minimal Python 3.11 base.
#   - ``git`` installed for artifact clone.
#   - Code mounted from /mnt/user/appdata/multica/coordinator at runtime
#     (bind mount), so edits on the host are live without rebuilding.
#   - Writable state at /var/lib/coordinator (bind-mounted to
#     /mnt/user/appdata/multica/coordinator-state on host).
#   - Shared rounds tree at /mnt/user/appdata/multica/rounds — mounted at the
#     SAME absolute path inside every judge daemon so filesystem paths in
#     chat-task prompts resolve identically in both sides.
#   - Network: ``multica`` (so COORDINATOR_SERVER_URL can resolve
#     ``http://multica-backend:8080`` directly).
#
# Runtime env vars (set on ``docker run``):
#   COORDINATOR_SERVER_URL        http://multica-backend:8080
#   COORDINATOR_WORKSPACE_ID      <multica workspace id>
#   COORDINATOR_TOKEN             mul_... (user PAT; required for chat endpoints)
#   COORDINATOR_GITEA_BASE_URL    https://git.wylab.me   (optional)
#   COORDINATOR_GIT_USERNAME      m-coordinator          (optional)
#   COORDINATOR_GIT_TOKEN         <gitea PAT, read-only> (optional; ephemeral)
#   COORDINATOR_ROUNDS_ROOT       /mnt/user/appdata/multica/rounds
#   COORDINATOR_STATE_DIR         /var/lib/coordinator
