**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The MQTT 5.0 specification defines the Session Present flag in CONNACK to indicate whether the server has a stored session for the client. `ConnectHandler` always sets `session-present=false`, which violates the protocol when a client reconnects with `Clean Start=false` and the server does have a stored session. **Severity:** Medium — protocol compliance issue; affects clients that rely on session resumption. **Suggested Fix:** Check the session store in `ConnectHandler` before building the CONNACK, and set the Session Present flag based on whether a session exists for the client ID. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
