Keep room identity clear through reconnect
Begin with one topic and the room a participant intends to rejoin. Agree what identifies that room independently of a title that may change. Decide what the client retains while disconnected and how it verifies access again. A room that has closed or become unavailable needs a defined return state. Review switching topics before the earlier connection recovers so late events cannot appear in the wrong conversation. The visible room context should remain understandable throughout the recovery.
