- voice_recorder: proper mkdir with errno/EEXIST check, errno logged on fopen failure
- MessageBubble: pointerInput wrapped in while(true) so PTT works after first gesture
- PTT Box: same composable identity in idle/recording states (just changes bg color)
Gesture coroutine survives recomposition → onPttReleased() fires on finger lift.
When locked, Box is replaced by cancel/send IconButtons.
- Min voice duration: 500→1000ms (C and ViewModel)
- voice_recorder: compressor config API (max_gain, lookback, lookahead, rise_rate, target_level)
- bridge/JNI: compressor_config export
- AudioRecorderManager: startMicTest/stopMicTest for level preview
- SettingsScreen: TabRow with Settings + Audio tabs
- Audio tab: mic test with live level bar, Opus preset selector, 5 compressor sliders matching desktop
