Report the stop on macro/run/status (phase `error`, message `aborted`). This is a network message: it cannot reach an offline gateway and is NOT a safety function — an emergency stop must be hardwired. The backend does not validate what it publishes — this schema documents it. New optional keys may be added within v1; ignore keys you do not use.",
