A start writes the pipeline's key (watched branch, source revision, module) only when it is absent and says
pipeline-started; a second start of the same revision and module writes nothing. A package-published asks the
catalog's outdated for that package on that branch, a kept call, and starts a pipeline for each dependent behind
by kind 1, keyed by the publication's branch and source revision. The start on take-in.taken, and a gathered
group's one pipeline per branch, wait for take-in.taken's body (design 47 G §476, in review).
Builds: design 47 G §54, §103, §334, §53, §75

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).

The runner's tools bundle serves the seat mesh-pipeline-runner's read verbs as tools named
<seat>.<verb>, answered from its own states pipelines and kept, never another part's: show one
pipeline whole with its steps and their outputs' names, list by module, branch, commit or run newest
first, stands every step started and not ended with what it waits on and since when, why-carried the
pipeline a carried step came from, kept the kept results by level, digest or package.
Builds: design 47 G §83, §306, §75 (stands), §25 (why-carried)
Not built, waiting on design answers: show's step log (Q-RN6, the step log's section form) and each
store's fill against its cap in show and kept (Q-RN2, where the caps are declared).

The module mesh-delivery-pipeline claims the seat mesh-pipeline-runner, serving its twelve verbs,
asks no template, keeps pipelines, kept, aged, findings and its first views in old state sections,
its step log on an old stream (128 MiB) and its step outputs in an old objects section (1 GiB),
hears the events its pipelines start and end on, and needs the assigner's program delivered first.
Its program stops when its state pipelines cannot be read; its own module is its account's.
Builds: design 47 G §1, §21, §27, §59, §85, §95, §101, §130, §333
Not built, waiting on design answers: §76's health check (its tool's name), §85's caps of the old
state sections (no size field on an old state), step-log's 100 days (the validator's 30-day bound),
and §59's sent-objects (the objects template's cap the design names has no default).
