+## Implementation Status: COMPLETE ✅
+
+All development phases are complete and ready for live testing:
+
+✅ **Phase 1**: Foundation (database, config, feature flags)
+✅ **Phase 2**: Backend Integration (API clients, webhooks)
+✅ **Phase 3**: Frontend Migration (platform components)
+✅ **Phase 4**: Testing & Validation (comprehensive test suite)
+
+**Next Steps**: Obtain Daily.co credentials and run live integration testing before gradual rollout.
