Root-cause fix for the 2026-07-03 run stalling: the cc-ci host disk filled to
100% (ENOSPC) mid-run (Wave 6, lasuite-drive), the agent stopped to reclaim
space, and nothing resumed it — the log-idle/429 watchdog only covers opencode-go
usage-limit stalls, not an environmental wedge.
- launch-upgrader.py: step-0 prereclaim_cc_ci() prunes STALE cc-ci docker images
(unused AND older than a week, so this week's likely-reused images stay) before
each weekly run. Best-effort; env-tunable (UPGRADER_PRERECLAIM*).
- launch-supervisor.py (new): hourly glm-5.2 orchestrator wake-up. Cheap
deterministic gate — no-ops (zero tokens) when the run is complete or
progressing; only when a run stalled/died before completing does it launch a
short-lived glm-5.2 agent to diagnose + drive it to a clean DONE. Progress is
judged by live run-proc + log mtime (session_busy() is claude-tuned and misreads
a headless opencode run as idle).
- configuration.nix: cc-ci-upgrade-supervisor service + hourly timer (:07).
- upgrade-all SKILL §0: note the stale-image reclaim for manual runs.
