bus-state is answered with no credential of a consumer's own, so ADR 0603 §5 counts the provider's own have: the
assigner reads, per pass, what the running healthy builds on online nodes offer (their manifests through the builder's
builds) and holds a consumer with a bus-state entry under the provisions' rule until one offers it, handed or not and
with no provisioner key. The words name bus state, and the delivery view names the edge from them.
