Module nick 

Nick stored on messenger_sessions. The HTTP layer stamps member display names from effective_label and refuses create/invite when require_nick fails. set_nick writes that session row. There is no reserved-nick list, no cooldown, and no billing. matrix_users.nick is not the source of truth.

Structs

MessengerSession

A client session. The nick is this row. device_id is only a mark.
