Deploy Staging / build (push) Failing after 1h1m21s
fix: auto-healer v5 — fix blocking bug, complete SRE flow verified
- Fixed blocking  command in incident reporting (added timeout 5s + --until now)
  Was causing the entire agent script to hang forever after saving each incident
- Full SRE flow now works end-to-end:
  1. Detect fault → 2. Fetch logs → 3. Analyze against knowledge base
  4. Save incident with full context (logs, inspect, events, resources)
  5. Execute restore protocol (rollback to :rollback image)
  6. Verify service restored
- 3 incidents successfully captured and logged with diagnostics
- All containers healthy, auto-healer monitoring every 30s

## Error Knowledge Base
| Log Pattern | Root Cause | Action |
|---|---|---|
| "Cannot find module" | Missing dependency | **Rollback** |
| "unexpected token" / "SyntaxError" | JS parse error (bad deploy) | **Rollback** |
| "heap out of memory" / "FATAL ERROR" | OOM / memory leak | **Rollback** |
| "ReferenceError" / "TypeError" | Code bug | **Rollback** |
| "PrismaClientInitializationError" | DB connection issue | Restart container |
| "ECONNREFUSED" / "ENOTFOUND" | Downstream unreachable | Restart container |
| "rate limit" / "429" | Rate limiter | Hotfix (auto-cleanup) |
| "jwt expired" / "invalid token" | Config issue | Check config → Rollback |
| "500" / "unhandled rejection" | Unhandled exception | **Rollback** |
| Container exit 137 / OOMKilled | SIGKILL / OOM | **Rollback** (if repeated) |
| Gateway 502 | nginx down | Reload gateway |
## Restore Protocol Steps
```bash
# 1. Save incident
cat > /var/log/falah/incidents/incident_$(date +%Y%m%d_%H%M%S).log << 'EOF'
... full diagnostics ...
EOF
# 2. Rollback
docker stop falah-mobile-staging
docker rm -f falah-mobile-staging
docker run -d --name falah-mobile-staging \
--restart unless-stopped \
-p 4014:3000 \
-v /var/services/homes/admin/falah-mobile/data:/app/data \
--network falah-umbrel_falah-system \
falah-mobile:rollback
# 3. Verify
curl -f http://localhost:4014/mobile/api/health
# 4. Report
echo "Incident: $id — rolled back to :rollback"
```
## Hotfix Actions (no rollback needed)
- **Rate limit**: Restart container (code auto-cleans every 5 min)
- **DB connection**: Restart container (reconnect)
- **Gateway**: `nginx -s reload`
## Escalation
If 3+ restarts/hour or rollback fails:
1. Log full incident with all diagnostics
2. Do NOT restart again (leave for manual debug)
3. Alert via available channels
