// **An ask the build seat gave up on ends its step** (novox/hq issue 734): mesh-sdk buildrun.LostAskWaiter hands the

|
// waiting asker a failed step on the node buildrun.LostNode when DEAD_LETTERS keeps the ask's copy (buildrun.HearDeadLetters,
|
|
// granted by buscompose DeadLetterReads), and, under buildrun.NotTakenBound, when no build node took the ask within the
|
|
// bound. What follows is the checker's: a try ends as error (Tryer.run), with the not-taken bound at the step bound
|
|
// (Tryer.NotTaken); a check is asked again under its claim, at most LostAskTries times, then fails as not heard and is
|
|
// judged again when the nodes change (Checker.try). A check's ask has no not-taken bound: it waits in the stream as long as
