defs.Wait has the fields of a wait (owner, step compose or kept-build, node, on, bound, since, clock-from, words, reason)
and, in the have, ask-at and act; wait-held.<node>.<module> and wait-ended.<node>.<module> are kept last per subject on
the stream running is kept on; the have's value gains wait, waits stays. Generated code waits for K21.
Builds: design 47 G §498, §499, §541, §556, §560, §629
