Three ways the orphan sweep could still SIGKILL live user work. `shellIsForeground` was `tpgid === pgid`, a foreground-only predicate. Measured on a real `bash -i` on a real pty: a shell holding `sleep 300 &` and a shell holding a Ctrl-Z'd job both read `pgid == tpgid`, `Ss+` — byte-identical to an idle prompt. Only the job's own row differs. So `pnpm build &` and a suspended editor were each attested idle, and the stop that follows SIGKILLs every process group on the tty. It is now `shellOwnsEveryTtyProcessGroup`, measured over the same set of process groups the kill would reach, and false when anything on the tty is stopped. No new probe: `tpgid` already identifies the terminal, because a process group has one session and a session at most one controlling terminal. `capturedAgeMs` was hardcoded to 0 by a producer that awaited the snapshot once before a loop that may await per entry, and it had zero readers anywhere. It is now stamped from when the capture was taken — deliberately as an upper bound, since the table is TTL-shared — and the sweep refuses evidence older than its own pass budget, counting its own elapsed time since the listing arrived. Stale degrades to "do not sweep", never to "sweep". The display consumer of the same measurement keeps no age budget, now as a stated decision rather than an accident. `pty.shutdown` took no request context while `pty.spawn` and `pty.attach` both did, so the ownership rule was enforced client-side only on the one irreversible call. It gains an optional `expectedOwnerClientInstanceId`, symmetric with the incarnation fence already there; the host refuses unless the connection still authenticates as that identity AND it recorded that identity at spawn. Rule 1: no reader requires it, an ordinary teardown omits it, and an old host ignoring it behaves exactly as today. The load-bearing test joins the real publisher to the real client reader over `ps` captured verbatim from a container. Reverting the predicate fails the backgrounded and suspended rows and nothing else.
