Main now reconnects on a peer normal close (reconnect_on_normal_close), so transport completion is signal_cancel or a policy close: drop normal_close from the completion matrices and let the linkclose model accept a run that ends by raising AgentDisconnectedError with its typed reason, as the surface feature specifies.

A peer normal close reconnects now, so the startup-cannot-restore-health case needs a close that truly ends the supervisor.

Summary
This gives managed hosts an immutable view of agent and room state without polling private runtime structures. Synchronous
Agent.status()andPlatformRuntime.status()return I/O-free snapshots; they observe the existing lifecycle owners rather than becoming another lifecycle authority.AgentStatusandRoomStatusmodels covering running/connected state, terminal disconnect cause, successful-start timestamp, room membership, routing, execution state, and unsettled ownership.cleanup_pendingvisible while initialization, adapter cleanup, runtime resources, or single-instance guards remain owned. A disconnected agent with unfinished cleanup is not reported as cleanly stopped.Prerequisite
Depends on public terminal-disconnect handling in #843.
Validation
Loopback WebSocket tests cover immutable snapshots, membership and execution transitions, reconnects, shutdown during startup, failed/cancelled cleanup, and restart.
