A muscle sensor or a sip-and-puff tube does not produce clicks — it produces a messy analog signal that drifts, spikes, and never quite sits still. Something has to decide when it means "I intend to activate." That decision is where assistive switches usually fail: too eager and the interface fires while you rest, too timid and you cannot reach it at all. This is the pipeline, running live.
Not calibrated — the detector will not fire until it has measured your resting level and your strongest effort. That refusal is deliberate.
