Staircase 0.1.8 — streams: a msg_sub_many the coordinator never starts (request on a relay it was not reading) fails after 30 s and retries, and a chat reads live only once the stream started (it stayed "live" with nothing arriving until restart); sync: a parked group holds sends and commits until it reads again (a parked desktop sent messages nobody could read), a skip is checked against the next message (undone if that one is unreadable too, sends held until confirmed if nothing follows), a parked group whose cursor moved past clears; ui: stuck-chat banner with Skip it / Details, selectable connection details, member actions in a menu, Tab completes a mention; zapstore listing and changelog
