W16.6: the tool runner reads which modules exist and their manifests from the catalog half through meshcatalogclient's branch follower on its own consumer (milestone 47/G)

Browse Source 
firstview adopts the shared branch follower over a wiring of its own consumer (views held with the assigner's, findings through its
held writer, events routed to each adopted view); the console's Source gives Modules from the catalog entries, the manifest an entry
carries whole; the indexer's modules and manifests first views and their consumes are removed, the registrations and the gate's
source-moved are consumed.

Builds: design 47 G §196, §594, §614; lead answers A-5, A-27, A-103
