//! Voice Live: a push-to-talk spoken assistant over Minutes' memory (RFC 0007).
//!
//! The user holds a key, talks, and hears an answer. A realtime speech model
//! (phase 1: Gemini Live) does the listening and speaking; every fact comes from
//! a tool call into this crate. This module is an optional, cloud-backed,
//! failure-isolated consumer: it opens its own microphone stream, it refuses to
//! start while a recording is active, and nothing here can touch capture state.
//!
//! Layout: [`protocol`] speaks the wire format, [`audio_out`] plays model audio,
//! [`names`] biases and resolves people's names, [`tools`] dispatches into core,
//! and [`session`] ties them together on one thread per session.
