The keeper is asked by a person through its own state requests (CAT-N8); the acting verbs
are served by nobody on the bus and denied to every principal whose grant reaches them. The
bus module's tools bundle may read its module's own stream back (nats_history).

The part hears the bus module's own stream on its durable consumer there. That consumer did
not exist: since the controller ended (ADR 0590) nobody created a module's consumer on a
module stream it hears (AccountConsumers left them to the controller), so it is created now
with every account consumer, and a pass that created consumers wakes one more pass so the
part's own hearing opens at once. Bindings are kept per module under bound.<module>.

ADR 0593 §1: buscompose's engine moves from mesh-sdk into mesh-grants/internal/buscompose, its golden
user lists unchanged; the controller's raise and assert code is left behind, and the merged switch
test runs inside the part's whole integration test.
