   minutes are a constant; an expired step ends `could not run` and the others run on. The runner's write verbs wait on

+  `mesh-broker`'s verbs and sends the chunks itself; the builder's process serves `reserved` and `builder_build`; the
+  runner's process serves `review`, `rerun`, `accept` and `cancel`, writing `pipelines` by compare-and-set; the chunk
+  subjects go to the process that answers.
