/**
 * A restart loses the conversation, not the journal.
 *
 * Found live: the pod rolled to a new image mid-run, and every job the master was waiting on
 * answered 404 — "no such job" — even though its journal sat on disk. A 404 is unreadable to a
 * caller (transient error, or gone forever?), so the master left those runs `started` indefinitely
 * and the ONE browser session stayed occupied by work that had already ended. An interrupted job is
 * the honest answer: terminal, with everything it found before the restart still in the record.
