The finite endpoint is not permanent evaporation

The cutoff in Corollary cor:tolerance retains one physical qubit before any terminal readout. A stopped program can then remove its name from the returned interface, but its physical state and complete environment have not been annihilated.

A fixed finite autonomous Hamiltonian with a fixed access partition can have arbitrarily late recurrences of its complete channel. This follows by simultaneous recurrence of its finitely many eigenvalue phases. It is a different model from a terminated, isolated-output schedule CheungHawk04AB. Neither finite termination nor recurrence proves a gravitational pinch-off or disappearance of a universe.
