Root cause: abiba-zulip extension had STUCK_THRESHOLD_MS=30min.
After 30min of inactivity (overnight), it reported stuck=True, which
triggered the health monitor to restart it — cycling restarts up to 18.
Permanent fixes:
1. STUCK_THRESHOLD_MS raised 30min → 4 hours in extension index.js
2. PM2 restart counter reset: delete+re-add abiba-zulip (was 18, now 0)
3. pm2-self-heal.sh alert threshold documented at 30 (implementation already)
4. Prose contract updated with historical note and threshold rationale
- Added --no-color flag to all PM2 commands
- Self-process guard: abiba-zulip is READ-ONLY, never restarted
- Corrected column indices (PID=6, restarts=8, status=9)
- Added pm2-self-heal.sh shell script implementation
Responsibility contract that checks abiba-zulip and abiba-telegram
every 5 minutes. Restarts stopped/errored processes, escalates if
restart count exceeds 5/hour. Logs to knowledge graph and alerts
owner via Zulip DM.
