Server and core: version ranges on both sides with a coded refusal; a client id maps to the same member and token for the server's life; a drop is `gone` for a 10-minute grace keeping ready, presence, queue items, relay and avatar; `bye` leaves at once; ordered takeover (seq, replaced/stale); presence joining/in/away/gone with one PresencePolicy; joiners never pause playback and hold a held gate at most ~15 s; state.hold; feed ids, seq and replay; the relay lives through its source's grace and continues on re-dial; queue `by` lasting, auto items and cancel; MediaRef carried; client ids never logged. App: persisted client id and seq; Connection with unstable/lost/ replaced states, backoff with jitter, no lost/back pair per flap; a drop keeps the session (state, player, media, relay source); presence in the strip and members card; sit out = away intent; feed matched by id; auto sit-out (idle when not playing, minimised for a while; never when alone) replaces auto-unready; bye on close and Leave, not on update restart; relay source re-dials through its grace.
