The per-machine form gains the keys below the machine's own, <node>.>, for every per-machine state and a membership's too (PerMachineKeys), every module's key keeping its form; buscompose exports WirePattern, which a reader uses to turn a stream's events into the bus's subjects (the tool runner's marks).
