Operations Documentation

🚨 Runbooks

When things go wrong at 2am, these runbooks provide step-by-step incident response procedures:

• Server Won't Start - Port conflicts, TLS errors, WAL corruption
• High Query Latency - Performance degradation, replication lag
• Quarantine Overflow - Content defense queue management
• Circuit Breaker Stuck - Agent bans and manual resets
• Restore from Backup - Disaster recovery procedures
• Disk Full - Storage management and WAL cleanup
• Add Node to Cluster - Cluster expansion procedures

Start here: Troubleshooting Flowchart - Decision tree from symptom to runbook

🏗️ Reference Architectures

Choose your deployment model based on scale, availability requirements, and operational maturity:

Architecture	Target	Assertions	Queries/sec	RTO/RPO	Guide
Single-Node Pilot	PoC, friendly pilot	<10K	<100/sec	2hr / 24hr	Guide
Three-Node Cluster	Production	<100K	<1K/sec	5min / 1min	Guide
Enterprise (future)	Large-scale	>100K	>1K/sec	1min / 0min	Roadmap (P6+)

Also see:

• Network Requirements - Ports, firewalls, TLS, DNS
• Resource Sizing - CPU, RAM, disk calculations

📦 Deployment Examples

Infrastructure-as-Code examples ready to customize for your environment:

• Docker Compose + Monitoring - Turnkey deployment with Prometheus + Grafana
• Nginx Reverse Proxy - TLS termination, rate limiting, security headers
• Envoy Gateway - Advanced load balancing, circuit breakers, retries

---

✅ Pilot Success Criteria

Before going to production, validate your pilot meets these criteria:

• Pilot Success Criteria - Performance, functional, operational requirements
• 5 Amazement Moments - Demo validation checklist
• Acceptance Criteria - Must Pass / Should Pass / Nice to Have

Common Tasks

First-Time Deployment

1. Review Single-Node Pilot Architecture
2. Follow Resource Sizing Guide to choose hardware
3. Deploy using Docker Compose example
4. Configure reverse proxy (Nginx or Envoy)
5. Validate against Pilot Success Criteria

Incident Response

1. Identify symptom (error message, alert, user report)
2. Check Troubleshooting Flowchart
3. Follow relevant runbook (see list above)
4. Document resolution and add to runbook if new scenario

Scaling to Production

1. Validate pilot success with Success Criteria
2. Review Three-Node Cluster Architecture
3. Plan migration (data backup, node provisioning, DNS changes)
4. Execute deployment with rolling validation
5. Set up monitoring (see Docker Compose example)

Prerequisites

Before using these operations guides, ensure you've completed:

• ✅ Production Readiness Verification - 84% CLI score, all critical checks pass
• ✅ Load Testing - 10K assertions baseline, 1K/sec sustained
• ✅ Backup/Restore Testing - Validated roundtrip recovery
