A module hears what it consumes: its consumer is raised with the bus, and it pulls it

Every module moved onto the bus by the rollout was issued on the old one, so none had a consumer
waiting; and the grant named a push delivery a runtime's client never binds, while the pull it
does make — asking about its consumer, asking it for messages — was refused. The consumers a
module's declarations imply are now raised whenever the bus is, and the grant is the pull.
