A `pty.attach` reply carrying `sourceRecovery: restoreRequired` is the relay answering for a PTY it just found in its pool and proved alive with `isProcessAlive`; only the stale output delivery was retired. Main converted that into `SSH_SESSION_EXPIRED`, which is the token every caller uses to retire the pane binding and cold-restore the agent, so a transient reconnect started a second `claude --resume` over a running one's transcript and left the previous remote PTY detached — one more per reconnect until the host refused to fork. Retry the attach once (the relay retires the stale delivery as it answers, so the next attach opens a fresh one with full replay), then fail with a restore-required verdict that makes no claim about absence. Callers already route anything short of absence to the unverifiable pane-recovery path. Also tighten the renderer's expiry verdict, which was a bare substring test: an identity mismatch names a LIVE PTY owned by another pane and observes nothing about this one, and main's own gate already refuses to respawn on it.
