📝 Notes

The PHASE 3 implementation has made significant progress with the core infrastructure now fully operational. The main blocker (gRPC version compatibility) has been successfully resolved by:

1. Updating protoc-gen-go-grpc to v1.3.0 - This resolved the version compatibility issues with the gRPC library
2. Regenerating all protobuf files - Ensured all generated code is compatible
3. Fixing import paths and utils references - Resolved all build errors in gRPC client files
4. Adding placeholder implementations - Temporarily implemented missing service methods to get the system running

The system now has a solid foundation with both HTTP and gRPC servers operational. The next phase can focus on implementing the advanced streaming features, enhanced collaboration capabilities, and completing the service method implementations.

🚀 Current Capabilities

• HTTP Server: Fully functional with all REST endpoints
• gRPC Server: Operational with EventBus and InterServiceCommunication services
• Database: Connected and running with all migrations applied
• Authentication: Working with JWT tokens and gRPC authentication
• Inter-Service Communication: Basic framework in place with placeholder implementations
• Event Bus: Basic structure ready for real event handling
• Graceful Shutdown: Both HTTP and gRPC servers shut down properly

The foundation is now solid and ready for the advanced features implementation!
