## 📈 Performance Targets

| Metric | Target |
|--------|--------|
| API Response Time (p50) | < 500ms |
| API Response Time (p99) | < 2s |
| DB Query Time (p99) | < 200ms |
| Job Latency | < 5 min |

---

## 📊 Operational Dashboards

1. **Batch SLA:** Queue depths, job times, latencies
2. **Data Quality:** DQ-classified jobs, manual review queue
3. **Duplicate Detection:** Outbox events, inbox messages
4. **Model Drift:** OOS performance, backtest divergence
5. **System Health:** Host uptime, DB replication, error rates

---

## 🚨 Incident Procedures

### Job Stuck (Distributed Lock)
1. Check Hangfire dashboard
2. Query: `SELECT * FROM hangfire.lock WHERE Key = '...'`
3. Delete stale locks if > 10 min old
4. Monitor next scheduled run

### Outbox/Inbox Deadlock
1. Count pending: `SELECT COUNT(*) FROM outbox.outbox WHERE published_at IS NULL`
2. Check job logs for DB errors
3. Manually trigger OutboxPollerJob

### Auth Failure (FailClosed)
1. Verify ASPNETCORE_ENVIRONMENT = Production
2. Check appsettings.Production.json
3. Verify API key format

### Performance Degradation
1. Check queue depth and job times
2. Scale Hangfire workers if needed
3. Check application memory usage
4. Review slow query logs

## 📝 Deployment Steps

1. [ ] Backup production database
2. [ ] Stop Host (graceful)
3. [ ] Deploy binaries
4. [ ] Run DbUp migrations
5. [ ] Start Host (-c Release)
6. [ ] Verify health check
7. [ ] Monitor first 24 hours

---

## 🔄 Rollback Procedure

1. Stop Host
2. Restore database from backup
3. Deploy previous binaries
4. Restart Host
5. Verify gates pass
