- Research direction
- Investigate how messages are sent and received in the cim project, focusing on the client server communication logic. The issue mentions no acknowledgment receipt after message delivery. Look at the current protocol implementation (likely in the cim server and cim client modules) to identify where ack handling is missing. Consider adding a simple ack response after message receipt, possibly by extending the existing message types or protocol. Review the comments on the issue for any suggested approaches.
