Nothing reconciled the relay's live PTY list against what the app still tracks, so a pane whose id the client lost held a relay slot until the daemon died — the "Maximum number of PTY sessions reached (50)" wall. #9819 proposed sweeping any pane-bound PTY "the app no longer owns or leases". That is not proof of orphanhood: absence from a client-side set is `unverifiable` by construction, and a second machine on the same build attaches to the SAME relay, where its live agents are missing from this client's store for exactly the same reason a real orphan is. So the host attests instead. PtyHandler records the authenticated consumer identity behind the connection that asked it to spawn each PTY, read from the live grant rather than from a spawn parameter, and publishes it on pty.listProcesses alongside a host-measured age and whether the PTY is pane-bound. A client may stop a PTY only when the owning host names THIS client as its creator, this client holds the negotiated session-owner grant, the PTY is pane-bound, older than 30s, carries no adoptable agent session, and this client has no lease, live route or pending stop for it. Every stop is fenced on the incarnation the same listing published. All three published fields are optional (Rule 1), and every absence reads as unknown: against a host that predates them the sweep stops nothing. Revived PTYs are deliberately left unattested.
