Closes the last live route to the reported duplicate agent resume (RC2), found by the E2E harness rather than by reading: when a relay is stalled and replaced, the fresh relay has no memory of `pty-1` while the old shells keep running under its predecessor. It answers not-found, and the renderer read that as proof. A not-found means the relay WE ASKED cannot hand that id back. That proves an exit only if the relay process that minted the pty is the one answering. The design says exactly this (D3 row 2), and gates the grant on `relayInstanceId` equality — a field step E-2 never built. `SSH_SESSION_EXPIRED` is not independent evidence either: its ONLY producer is that same not-found mapping in reattachSshPtySession, and the token's own doc comment claimed "the host proved the session is gone", which it never did. So `isProvenSshSessionGoneError` returns false. Both reattach arms now always take the non-proof path and surface the pane as disconnected, which is what the owner approved in D1 — and what makes that affordance load-bearing rather than near-unreachable, since it was previously only reached by errors that were already rare. The respawn tails are deliberately NOT deleted. The design preserves the grant as a conditional for E-2, so the decision point stays and a clause pins that nothing reaches it meanwhile. This is the one place in the program where an unreachable branch is kept on purpose, and it is labelled as such. Tests: three clauses asserted a not-found proves death and are INVERTED, with the reasoning recorded. The #12101 cold-restore case reached the spawn door by throwing a not-found; that door is now opened by the user's "Start a new terminal", so the test drives that instead and keeps all four of its original assertions verbatim — strictly better coverage, since it now pins that the automatic respawn stopped AND that the door still works. Mutation proof: restoring the old predicate makes the new no-respawn clause fail with "expected connect to be called 1 times, but got 2", confirming it reddens on the real production route rather than passing vacuously.
