A check ask handed out five times during a bus reload was given up into DEAD_LETTERS and no build node wrote a step for it, so try-1793017340003993788 stayed running for ever, held one of the four try places, and checker_try of its head kept answering its id. The checker now hears the copies DEAD_LETTERS keeps of the build seats' given-up asks (an ordered consumer from its start; the grant is mesh-sdk/mesh-controller DeadLetterReads, branch fix/734-lost-ask) and ends the step it waits for: a try ends as error saying why, a check is asked again under its claim, up to three times, then fails as not heard. A try whose ask no node takes within the step bound ends the same way (a check's backlog stays no fault, ADR 0525 §9). checker_try_end ends a try by hand, freeing its place and stopping its judging.
