 # Phase 6: Observability & Production Readiness
 
 ## Overview
-Complete observability setup with OpenTelemetry, integrate error reporting with Sentry, enhance logging with correlation IDs, and add rate limiting.
+Enhance observability with full OpenTelemetry integration, add comprehensive error reporting (Sentry), create Grafana dashboards, improve logging with request correlation, add rate limiting and security hardening, and optimize performance.
