ReadonlydetourThe detour a challenge over the work's requests is answered with. The
launch's tail carries the call's own (otherwise answers a challenge over
a tail request, between the caller's actions); a timer carries none (a
timer is not an effect the screens run, so its challenge keeps its failure
and, session-fatal, ends the process typed).
ReadonlyleftWhat the work left besides ending the process, read after the one judgment
below: ended says whether that judgment ended the process with it. The
set records it as its outcome; a timer ends the process with a defect that
escaped it.
