- Wire audit store into session routes (session.create, prompt.submit events)
- Wire audit store into audit export routes (persistent-first, telemetry fallback)
- CSRF double-submit cookie pattern (token generation, cookie set, header validation)

Production:
- Helm chart CI: helm lint + helm template validation
- Database migration CI: verify step in pipeline
- Prometheus alerting rules (error rate, latency, pod restarts, memory, CPU, queue, health)
- Rate limiting per API key (3x IP limit, sliding window, advisory)
- WebSocket SSE fallback (auto-downgrade after MAX_RETRIES WS failures)
