+cc-ci weekly-run SUPERVISOR — hourly glm-5.2 orchestrator wake-up.
+
+Fired hourly by a systemd timer. It is a CHEAP deterministic GATE first: if this week's
+/upgrade-all run is already complete, or is actively progressing, it does NOTHING and spends
+ZERO model tokens. Only when the run has STALLED or died before completing — e.g. the host
+disk-full crash on 2026-07-03 that the log-idle/429 watchdog does NOT cover — does it launch a
+short-lived glm-5.2 opencode agent that DIAGNOSES the blockage (disk, wedged deploy, dead
+session, a stuck recipe) and DRIVES the run to completion (resume the upgrader, ensure the
+summary + public report land). One-shot per fire; the next hour re-checks and no-ops if healthy.
+
+This is the intelligent complement to launch-upgrader.py's watchdog: the watchdog only handles
+opencode-go usage-limit (429) stalls (wait-out + `--continue`); the supervisor handles everything
+else that can wedge a weekly run, using a real model instead of a fixed heuristic.
+
+Usage:
+  launch-supervisor.py [check]   default — the timer entrypoint (gate; may spawn the agent)
+  launch-supervisor.py force     skip the gate; always launch the supervisor agent
+  launch-supervisor.py status    show what the gate currently sees
+  launch-supervisor.py stop      kill the supervisor agent session

+*** cc-ci WEEKLY-RUN SUPERVISOR — one-shot, glm-5.2 ***
+You are the hourly SUPERVISOR for the weekly cc-ci /upgrade-all run. A gate has determined the run
+is INCOMPLETE and not currently progressing ({reason}). Your job: get this week's run to a clean
+DONE — published report + summary — then STOP. You are NOT a perpetual loop.
+
+Your cwd is {WORKDIR}; reach the CI server with `ssh cc-ci`; creds in {WORKDIR}/.testenv; skills in
+{WORKDIR}/.claude/skills/. The stalled upgrader opencode session is {sid} (title "cc-ci-upgrader").
+
+DO THIS, in order — stop as soon as the run is healthy again:
+1. ENVIRONMENT FIRST. Check the CI server disk: `ssh cc-ci 'df -h / | tail -1'`. If root is > 85%
+   used, reclaim STALE images (unused AND older than a week, so this week's are kept):
+   `ssh cc-ci 'docker image prune -af --filter until=168h 2>&1 | tail -1; df -h / | tail -1'`.
+   Also glance for other infra wedges (a hung deploy, proxy VIP exhaustion — see upgrade-all §0).
+2. ASSESS the run. Read the upgrader session's recent output (opencode server {OPENCODE_SERVER},
+   `GET /session/{sid}/message`) and the open recipe PRs to see which enrolled recipes already have
+   a PR this week and which remain. Do NOT redo any recipe that already has a PR.
+3. DRIVE TO COMPLETION. Prefer to RESUME the existing run (context preserved) once the environment
+   is healthy: `python3 {WORKDIR}/cc-ci-plan/launch-upgrader.py resume`. Then CONFIRM it actually
+   restarted and is progressing (a fresh `opencode run … -s {sid} --continue` proc + the session
+   advancing). If the session is truly gone/unresumable, drive the remaining recipes yourself the
+   /upgrade-all way (per-recipe /recipe-upgrade DEFAULT-mode subagents, !testme verify), then make
+   sure the weekly summary is written to {WORKDIR}/.cc-ci-logs/upgrades/ and launch the public
+   report: `python3 {WORKDIR}/cc-ci-plan/launch-report.py fresh`.
+4. If on inspection the run is actually FINE (progressing) or already COMPLETE, do NOTHING.
+5. Print `SUPERVISOR DONE` and go idle. Do NOT loop.
+
+GUARDRAILS: NEVER merge a PR. NEVER weaken a test. DEFAULT mode only. Single-writer on the shared
+Swarm — don't pile concurrent deploys past DRONE_RUNNER_CAPACITY. Handing back to the resumed run
+is preferred over doing the recipe work yourself — avoid two writers at once.
