The lead's ruling of 13:0x (registry milestone): mesh-broker's events are mesh.seat.mesh-broker.event.<event> on the
shared events stream like every seat's. The grants part and the watchman consume mesh-broker.<event> and no longer hear
the bus module's own stream, which is its history for its tool. The keeper's process account is composed the seat's
event subjects, and the acknowledgement of a snapshot's chunks of each entry it keeps, which ADR 0626 §1 grants and the
composition lacked; a row holds it to no subscription of a restricted stream's subjects and no consumer of one.
