Membership lesson · Build Your Jarvis · Module 11 — Wake word

The name — a listener with a kill switch

The listener gets built — and its off switch is born in the same diff, before the doorman has ever woken once. The engine is the same on-device toolkit already running the ears and mouth: one more tiny model, and the member's chosen name defined as text — no training run, renameable in seconds, which means the 11.1 criteria get exercised against reality today. Detection is proven solo, the prove-it-solo pattern at its most apt: saying the name produces a logged wake event and a chime, and precisely nothing else, because nothing else is wired — the mic that doesn't sleep earns its way in one harmless proof at a time. The kill switch is absolute — listener stopped, not muted, the process not running — member-only, with the three-state indicator (off, asleep, awake) unmissable from the first launch. Rolling-buffer discard verified by construction in the review, and the aeroplane-mode test extends to the doorman: detection with the world switched off, because a name heard locally is the only kind worth answering to.
