A voice for Jarvis — ears, mouth, and three rules

The read-first opener for Module 10 — the module where Jarvis stops feeling like software. Before any code, the mental model: the local-first flip (2026 quietly made on-device speech genuinely good — fast, pleasant, free, and private, so the cloud became the upgrade rather than the requirement), the pipeline in plain English — ears, brain, mouth, with the brain completely untouched, because a spoken ask hits the same registry, gates and journal as a typed one — and the honest danger model for putting a microphone on an assistant that can act: mishears that become asks, other voices in the room (the TV, a video, a mate near an open mic — the genuinely 2026 attack), audio leaving home, and the creep of an always-listening mic. Three rules catch them: your voice asks and your hand approves, you see what it heard, and the mic is yours — push-to-talk only until Module 11 does always-on properly, with a kill switch. Member writes the voice brief: where voice would actually help their week, their mic rules, and how Jarvis should sound.
