PartitionExpired

The peer's reconnect window expired without recovery.

Emitted for non-host peers whose us.tractat.kuilt.liveness.PartitionEvent.PeerLost fires on the host or on any other room participant — i.e. genuine liveness-detected loss: the peer vanished without a clean us.tractat.kuilt.session.admit.AdmitMessage.Goodbye (crash, dead transport) and its reconnect window elapsed.

A clean leave never carries this reason: the departing peer's Goodbye reaches the host, which propagates an authoritative us.tractat.kuilt.session.admit.AdmitMessage.Farewell to every remaining member, so all of them evict promptly with Normal (#1292).
