Detailed Description
Abstract interface for handling messages from a subsystem.
Subsystems implement this interface to process their domain-specific messages. The handler is responsible for:
- Deserializing the payload into subsystem-specific types
- Executing the requested operation
- Serializing the response back into bytes
