The runner follows the registrations (a first view, then registration-changed) and, for each watched branch
they name, that branch's catalog half (a first view, then catalog-revision of that branch), each in its state
first-views, read by pipeline_first_views and asked again by hand with pipeline_first_view_again; past five
minutes without a view it writes view-waits. A step's status is read per module and artifact from the
registration, and the build seat of an artifact from the acting rule build naming its language.
Builds: design 47 G §21, §23, §323, §77, §195, §200
Open: design questions Q-RN7 (where a build seat's holder is read, §323) and Q-RN8 (a status left empty, §23).
