📈 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
