Add SysRS-303/304, SysDes-149/150/151, SRS-204/205/206/207,
SAD-081/082/083, SDD-094/095/096/097, DEC-029/030.
Captures the v1 lifecycle redesign:
- Drop manual Start-audio button; audio engine is bound to voice-channel
join/leave (ensure_running on first join, shutdown_if_idle on last
leave). Output stream opens regardless of mic-permission state so
listen-only is a first-class flow.
- TransmitMode enum (Ptt / Continuous / VoiceActivity-reserved).
Default Ptt on fresh install. Persisted per identity.
- PTT release tail: 200 ms default (0-500 ms configurable) before
transmit gate closes, avoiding clipped trailing syllables.
- Hard-mute toggle overrides transmit gate regardless of mode/PTT.
- Bridge surface: drop start_audio/stop_audio; add
voice_join(channel_id) / voice_leave() and BridgeEvent::VoiceState.
DEC-029 rejects Flutter global-hotkey packages (hotkey_manager,
super_hot_key) for PTT: they wrap RegisterHotKey/RegisterEventHotKey
which consume the key and don't fire key-up, wrong primitive for PTT.
Native Rust DesktopPttBackend (SDD-083/084/085) stays authoritative.
DEC-030 defers Voice Activity Detection to P1. RMS / WebRTC VAD /
Silero VAD trade-off review (binary-size, dependency-surface, CPU
profile) postponed; TransmitMode::VoiceActivity reserved on the enum
surface so a P1 increment is non-breaking.
Validator clean: 304/151/207/83/97 IDs, strict layered sourcing
preserved, no new warnings beyond the pre-existing 35 old-package-name
filenames.
