Delivered groundwork for a reusable gRPC command handling library and initial ControlEnvProxyServer scaffolding, exposed metadata listing endpoints and a TypeInformation RPC method to improve introspection, and simplified CLI usage to improve developer/operator experience. However, due to stability considerations, the ControlEnvProxyServer changes were rolled back and related files/references were removed to preserve mainline reliability. This period balanced experimentation with risk management, setting the stage for a safer, more modular integration in a future milestone.
