- Revert onset firing to the main thread (the background 'sequencer' thread was glitching the synth = trashy audio). Keeps mach-time anchoring + timing logs. - Stop: menuband.stop cancels every pending onset (play-generation token) and panics the synth (silence), clears the transport + robot badge. Relays over the MC fleet so a Stop on ANY machine ceases the whole score; MenuBandController gains panic(). conduct.mjs gains 'stop <hosts>' (reliable CLI cease) and now sends the score title so a popover can name the score in progress.
