+"""Update + logs for the matrix-bridge bot container on the Spark.
+
+matrix-bridge is a single Docker container managed by docker compose out of a
+git clone at `~matrix_bridge_user/matrix-bridge`. Status (the badge) and
+start/stop/restart ride the generic service machinery in `services.py`
+(`docker_state` / `run_action`). The two things that don't fit that mould live
+here:
+
+  - **Update** — `git fetch && git reset --hard origin/<branch> && docker
+    compose up -d --build`. Long-running (docker build), so it streams like the
+    vLLM `UpdateManager`: fire-and-forget job, SSE stream, fail-loud rc.
+  - **Logs** — a one-shot `docker logs --tail N` for diagnosing a red badge.
+
+We connect **directly as the configured user** (`modelo` — the repo owner), so
+git never trips its dubious-ownership guard and docker runs via the user's
+docker-group membership. We deliberately do NOT `sudo -iu modelo`: this Spark
+has no passwordless sudo, so a sudo wrap would hang in SSH BatchMode.
