Builders, the artifact store's tools and distribution read and write the registry reference form through the registry clients' reference package, and name the sweep seat from its contract (ADR 0634 §4, S-8; issue 1966)

catalogue's SeatReference, InRegistrySeat, Routed, Recorded, InArtifactStore and ArtifactSweepSeat leave mesh-sdk;
each package gives the two registry seats' names from their contracts (or the build step's copies of them).
