 ## Overview
 
-This document summarizes the documentation updates completed for task T010, which implemented the `CorsSettings` configuration structure as part of the CORS configuration feature (Phase 0.5).
+This document summarizes the documentation updates completed for the CORS configuration feature (Phase 0.5, Tasks T009–T016) and the subsequent US1 MVP implementation (Phases 2–4). All CORS tasks are complete, and the US1 feature (view and toggle relay states via web UI) is now operational.

 ## Conclusion
 
-The documentation for T010 (CorsSettings struct implementation) is **complete and comprehensive**. It covers:
+The documentation for the project is **up to date** and covers both Phase 0.5 (CORS) and Phase 2–4 (US1 MVP). Key accomplishments:
 
-1. **Configuration**: How to configure CORS for development and production
-2. **Security**: Critical security constraints and best practices
-3. **Testing**: All 5 TDD tests explained with purpose
-4. **Troubleshooting**: Common issues and solutions
-5. **Next Steps**: Clear roadmap for remaining CORS tasks
+1. **CORS Configuration**: Complete from research through implementation and integration tests
+2. **Domain Layer**: Type-driven design with 100% test coverage
+3. **Infrastructure**: Modbus TCP client, mock controller, SQLite persistence with factory wiring
+4. **Application**: Use cases for listing and toggling relays with health monitoring
+5. **Presentation**: REST API with OpenAPI docs, plus Vue 3 frontend with real-time polling
