 * Retry one immutable terminal payload without changing its outcome.

 * A timed-out attempt is retried, not abandoned: a hung connection is the
 * commonest transient failure, and abandoning it there would leave the rest of
 * the deadline unused. The timeout does not cancel the in-flight request, so a
 * retry can reach a gateway that already accepted the first one -- that is
 * safe because the gateway's terminal write is fenced
 * (`status = 'running' AND claimed_by = worker_id`) and answers a second
 * delivery with `already_finalized` rather than re-finalizing the run.
