Refuses a checkpoint that names another screen, reading only the id it
carries: the platform's restores run it before they build a process, so a
checkpoint of another screen costs nothing and sends nothing. A value that
names no screen is not refused here — it is damage, which the restore reports
as CheckpointDecodeError.
