EdisonJwa 78190c0694 feat(audio,android): wire engine + AudioManager JNI through ModeStack (SDD-108 §2)
Replace the prior one-shot android_engage_voice_communication call
with a ModeStack-mediated acquire/release pair. AudioEngine snapshots
the system audio mode on first acquire via android_get_audio_mode()
and restores it on last release via android_set_audio_mode(prior).
MODE_IN_COMMUNICATION (3) is engaged across the voice-session lifetime
per SDD-108.

Includes the Android AudioManager getMode/setMode JNI helpers
(placed in chanora_audio::engine alongside the existing JNI surface)
and the small ptt.rs touch needed for the SDD-108 ID-tag on the
existing tests.

Trace: SDD-108, SDD-115.

Edison Jwa dc9c5c0a4e feat: multi-platform bug fixes, Android audio path, and build tooling
Flutter UI fixes:
- Fix stale channel badge/speaker when moved by others (derive current
  channel from ownClientId instead of optimistic local state)
- Fix Linux PTT via focused fallback key handler
- Distinguish ServerQuery clients with terminal icon in client list
- Reduce duplicate current-channel badge display
- Prevent PTT key-bind save from permanently closing voice settings
- Fix Linux GTK reopen-after-close (quit app on window destroy)
- Fix focused PTT: consume key events, release held keys on
  disconnect/leave-channel/mode/backend changes, suppress stale errors

Flutter Rust bridge:
- Thread is_server_query flag through protocol→bridge→Dart
- Add own_client_id to BridgeSnapshot DTO
- Add log_file_path_str() for platform log path queries

Rust protocol:
- Add ServerQuery test coverage (query_client_type_maps_to_server_query_flag)
- Split reqwest TLS: native-tls for desktop/iOS, rustls for Android

Rust audio:
- Upgrade cpal 0.16→0.17.3 with API adjustments (SampleRate, description())
- Suppress Android-only dead-code warnings (open_log_file, keyring_account)

Android build tooling:
- tools/build-opus-android.sh: NDK auto-discovery, correct CMake
  Android variables (ANDROID_ABI, ANDROID_PLATFORM), portable baseline
- tools/build-android-rust.sh: build+copy Rust cdylib for arm64-v8a,
  armeabi-v7a, x86_64 into android/app/src/main/jniLibs/
- Add jniLibs/ to .gitignore

Rust bridge:
- Guard open_log_file() on non-Android (Android uses logcat)

EdisonJwa 9502580b5a chore(audio,ios): silence cpal-side dead_code on iOS + regen Podfile.lock (rc.8+62)
Two follow-ups after the iOS Rust build went green at 5de6ecc:

1. cpal-side framing constants (SAMPLE_RATE / FRAME_SAMPLES /
   MAX_OPUS_FRAME) are dead code in the current iOS commit
   because the VPIO callbacks are still no-op stubs and don't
   reach the constants yet (commits 3 + 4 will). They are
   genuinely live on every other platform via the cpal capture
   pipeline. Mark each with #[allow(dead_code)] and add a
   comment pointing at the commits that will reactivate them on
   iOS, instead of cfg-gating per-platform (the constants are
   framing invariants of the engine itself, not per-backend
   details).

2. ios/Podfile.lock regenerated on the Mac via 'pod install'
   to register package_info_plus (0.4.5) which landed in
   97a6ba6. Without this regen the Xcode build fails with
   'The sandbox is not in sync with the Podfile.lock' because
   Xcode's CocoaPods integration check sees a new plugin in
   pubspec.yaml that has no matching Pod entry. Five pods now
   in the lockfile: Flutter, audio_session, chanora_bridge,
   connectivity_plus, package_info_plus.

Build counter 61 -> 62 — the About dialog will display
v1.0.0-rc.8+62 so the user can confirm the build under test
matches this commit (the previous build said +61).

EdisonJwa 5de6eccc0c fix(audio,ios): correct ios_voice_unit imports + iOS stop() field access (rc.8+61)
iOS build of chanora_audio (target aarch64-apple-ios) failed with
four compilation errors after commit 2 landed. Root causes were
all simple symbol-path / cfg-gating mistakes from the skeleton
commit; the underlying design is unchanged.

1. ios_voice_unit.rs: wrong import path for OutPacket. The
   chanora_protocol crate re-exports it at the crate root
   (`pub use ...::OutPacket` in lib.rs line 52), not from a
   `voice` submodule (which doesn't exist).
   - use chanora_protocol::voice::OutPacket;
   + use chanora_protocol::OutPacket;

2. ios_voice_unit.rs: LinearPcmFlags lives in
   `coreaudio::audio_unit::audio_format`, not in
   `stream_format` (the doc page lists it under StreamFormat but
   the actual module path is the upstream Apple naming).
   - use coreaudio::audio_unit::stream_format::LinearPcmFlags;
   + use coreaudio::audio_unit::audio_format::LinearPcmFlags;

3. ios_voice_unit.rs: `Ordering` import unused (commit 1
   skeleton callbacks don't load atomics yet — that comes in
   commits 3 + 4). Remove from the std::sync::atomic import to
   silence the unused_imports warning.

4. engine.rs::AudioEngine::stop(): the existing body unconditionally
   touched self._input_stream and self._output_stream, but commit
   2 cfg-gated those fields away on iOS (and added an iOS-only
   _ios_voice_unit field in their place). Split the field drop
   logic with the same target_os = "ios" cfg so each platform
   only touches the fields it actually has.

Also clean up two pre-existing warnings exposed by the iOS cfg
gating:

5. engine.rs: `tracing::{error, warn}` were imported
   unconditionally but are only used inside cpal log lines.
   Cfg-gate the import to not(target_os = "ios").
6. engine.rs: `AudioData`, `CodecType`, `OutAudio` from
   chanora_protocol are only referenced in the Opus encoder feed
   inside CaptureState — cpal-side only. Cfg-gate to
   not(target_os = "ios"); keep `InboundVoice` + `OutPacket`
   on the unconditional path because the inbound forwarder + (in
   commit 3) the iOS capture pipeline both reference them.

Also fix a stray duplicate `#[cfg(not(target_os = "ios"))]`
attribute that landed on line 18 in commit 2.

Build verify (Linux host): cargo check -p chanora_audio clean
in 0.53s. iOS-side check pending on Mac.

Build counter bumped 60 -> 61 — the About dialog will display
v1.0.0-rc.8+61 so the user can confirm the build under test
matches this commit.

EdisonJwa 3b1724e970 feat(audio,ios): wire IosVoiceUnit into AudioEngine, cfg-gate cpal away on iOS (commit 2/5)
Split AudioEngine::start_with_gate into two backends:

* start_with_gate_cpal  — non-iOS path, the existing cpal + (SDL on
                         Linux) flow, renamed verbatim, no
                         behavioural change.
* start_with_gate_ios   — iOS path, constructs a single
                         IosVoiceUnit (VoiceProcessingIO via
                         coreaudio-rs) for combined mic + speaker.
                         Spawns the same inbound forwarder task
                         that pumps Opus packets into AudioHandler.

The public entry point start_with_gate dispatches at the top via
cfg(target_os = "ios") so callers stay backend-agnostic.

Struct field changes:
* _input_stream  : cfg-gated to not(ios)
* _output_stream : cfg-gated to not(ios), keeps the
                   Linux=SdlOutput / else=cpal::Stream split
* _ios_voice_unit: new field, cfg-gated to ios, owns the VPIO
                   AudioUnit for the engine's lifetime.

Module-level cfg-gating:
* All cpal-only helpers (try_open_capture, build_input_stream,
  build_output_stream, CaptureState + impl, ToF32 / FromF32 traits
  and impls, PlaybackResampleState) are now wrapped with
  #[cfg(not(target_os = "ios"))]. Same for the audiopus
  encoder + cpal trait imports — iOS doesn't pull libopus into the
  engine yet (commit 3 will, once the VPIO input callback wires
  into CaptureState).

Behaviour on iOS for THIS commit:
* AudioEngine starts cleanly, IosVoiceUnit::start succeeds (VPIO
  unit allocates + initialises + starts).
* Mic capture is dropped (the input callback is a no-op stub).
* Output emits silence (the render callback fills the buffer with
  zeros).
* Inbound forwarder still runs and pushes Opus packets into
  AudioHandler — they accumulate in the jitter buffer but no
  fill_buffer drain happens (commit 4 fixes that), so the buffer
  will grow up to MAX_BUFFER_TIME (~0.5 s) and then tsclientlib
  starts dropping the oldest frames. This is fine for now — the
  point of this commit is verifying the AudioUnit constructs +
  starts cleanly on the device. Audible silence is the expected
  state until commits 3/4 land.

Build verify (Linux host): cargo check -p chanora_audio clean in
0.53s. iOS-side compile happens on the Mac via the Xcode build
the user will trigger next.

EdisonJwa 6a4dbad60e fix(ios,audio): use AVAudioSession mode .default + correct mono downmix
Two changes that together address the user-reported 'speaker selector
not working' AND 'audio quality bad' symptoms on iPhone:

1. AppDelegate.swift: AVAudioSession mode .voiceChat -> .default

   .voiceChat binds the underlying AudioUnit's output element to a
   SINGLE physical transducer (the receiver/earpiece) at session-
   configure time. overrideOutputAudioPort updates AVAudioSession's
   route metadata so currentRoute.outputs reports Speaker, but the
   AudioUnit's output binding is stale and audio keeps routing to
   the original transducer. Net: tapping Speaker in the picker
   flipped the route in our log but produced no audible change.

   .voiceChat also enables iOS's telephony processing chain (forced
   mono output, aggressive AGC, heavy noise gating) which explains
   the 'garbled / watery / metallic' quality complaints.

   .default mode uses iOS's standard audio graph: stereo output, no
   AGC, no telephony post-processing, AudioUnit re-binds live when
   the route changes. Same mode Music.app and most non-telephony
   apps use. Trade-off: we lose iOS hardware AEC. If users report
   speakerphone echo we'll add software AEC (DEC-030).

   Category options unchanged \u2014 .allowBluetoothHFP +
   .allowBluetoothA2DP still permit BT headsets in both directions.

2. engine.rs::build_output_stream: mono device downmix fix

   The mixing path at dev_channels==1 previously wrote only the L
   channel of AudioHandler's stereo output into the single mono
   device channel and discarded R entirely. Anything panned right
   in the stereo voice mix was silently lost \u2014 on .voiceChat
   speakerphone (forced mono device) this manifested as quiet
   remote speakers being inaudible. Fix: when dev_channels==1,
   output = (L + R) * 0.5 instead of just L. The dev_channels>=2
   branch is unchanged.

   With change #1 iOS will typically expose stereo so this branch
   is rarely hit, but the fix is correct for any genuinely-mono
   sink (some BT car-audio profiles, USB mono headsets).

EdisonJwa 54ec8dd5a8 feat(audio): tune Opus encoder for VoIP (bitrate 32k, complexity 10, inband FEC, 5% PLC)
User report: 'sound heard are too poor' on iPhone iOS \u2014 garbled/
robotic + stutters/dropouts.

The Opus encoder ran with audiopus defaults: 'auto' bitrate that
drops to ~6 kbps during silence (sounds watery on speech resume),
inband FEC disabled (single packet loss = silent gap), no packet-
loss percentage hint (encoder can't budget bits for redundancy).

On lossy mobile networks (cell, WiFi roaming) this combination
sounds noticeably worse than the same Opus stream from a desktop
client. Garbled = silence-bitrate transitions; stutters = packet
loss without FEC.

Fix: tune the encoder once at construction with values derived
from RFC 6716 \u00a77.1 (Opus VoIP recommendations), Discord's voice
client tuning, and the Mumble defaults.

  * set_bitrate(32_000)        \u2014 sweet spot for mono speech. Below
                                  24 kbps starts to sound watery;
                                  above 64 kbps wastes bandwidth.
                                  Discord uses 64 kbps; Mumble
                                  defaults to 40 kbps; we pick
                                  32 kbps as a conservative VoIP
                                  value that survives ~100 kbps
                                  uplinks comfortably.
  * set_complexity(10)         \u2014 max quality. The CPU cost on a
                                  modern iPhone (A14+) or any
                                  desktop is negligible (~0.5 % of
                                  a single core for 48 kHz mono).
  * set_inband_fec(true)       \u2014 Opus inserts a low-bitrate copy
                                  of the previous frame inside the
                                  current packet so single-packet
                                  loss can be reconstructed from
                                  the next packet. Essential on
                                  lossy mobile. The decoder side
                                  (tsclientlib's AudioHandler)
                                  auto-handles FEC frames; no
                                  receiver-side change needed.
  * set_packet_loss_perc(5)    \u2014 tells the encoder to budget
                                  bits for 5 % expected loss.
                                  Higher values trade audio
                                  quality for resilience.

Each setter is wrapped in a soft-fail: if an exotic libopus build
rejects one of these, we log + continue with the still-functional
encoder rather than aborting the audio engine. info!-log a one-
liner per-engine-start summarising the tuned values so a future
diagnostic export can correlate audio reports with the active
configuration.

Application::Voip mode was already set (engine.rs:630, unchanged);
the new calls layer on top of that mode's defaults.

EdisonJwa d4c04b6a72 fix(ui,audio,ios,macos): eight P0 mobile fixes
User report from sideloaded iPhone build, in order of priority:

  #4 'Could not join channel: audio: audio backend:
     build_output_stream: The requested stream configuration is
     not supported by the device.'

     Cause: we forced cpal::BufferSize::Fixed(2048) on the output
     and input streams unconditionally on non-Linux. iOS CoreAudio
     RemoteIO units reject arbitrary buffer-size requests with that
     exact error. Windows WASAPI needs the pinning for shared-mode
     jitter, but macOS / iOS do not.
     Fix: cfg-gate Fixed(2048) to target_os = 'windows'; everywhere
     else use BufferSize::Default and let the platform HAL pick.
     crates/chanora_audio/src/engine.rs.

  #5 'Could not join channel: invariant violated:
     voice_in already taken'

     Cause: start_audio tore down the old engine BEFORE attempting
     to construct the new one, and consumed voice_in (an mpsc
     Receiver that can only be taken once) early. When the new
     engine failed mid-construction (e.g. because of #4 above) the
     session was left with: no audio engine, voice_in consumed,
     no way to retry without reconnect. The second voice_join
     attempt surfaced the invariant message.
     Fix: build the new engine BEFORE tearing down the old. Only
     swap state.audio if construction succeeded. crates/chanora_
     core/src/lib.rs::ChanoraSession::start_audio. Additionally
     added a put_voice_in helper to the protocol adapter (
     crates/chanora_protocol/src/adapter.rs) for a future
     broadcast-channel migration; the helper is unused on the
     immediate fix path but documents the intent.

  #3 'permission request would better on first open'

     Cause: AVAudioSession only triggers the mic-permission
     prompt the first time it tries to record. We never recorded
     until voice_join, so the prompt fired then.
     Fix iOS: AVAudioSession.sharedInstance().requestRecordPermission
     in AppDelegate.swift::application(_:didFinishLaunchingWithOptions:).
     Fix macOS: AVCaptureDevice.requestAccess(for: .audio) in
     macos/Runner/AppDelegate.swift::applicationDidFinishLaunching.
     Both run non-blocking; user can deny without crashing app
     launch, and voice_join then surfaces a clearer downstream
     error when the engine fails to open the input device.

  #1 + #2 'one-column upper takes too much space; Push to Talk
           button at bottom would be better'

     Layout rework for narrow-mode (single column, mobile shape):
     - Flipped the stacking order in main.dart so Voice Bar moves
       to the BOTTOM of the body and the channel tree (Expanded)
       fills above. Wide-mode (Row, >= 840 dp) layout unchanged.
     - Inside the Voice Bar on touch-only hosts, moved the
       on-screen Push to Talk button to be the LAST element of
       the Voice Bar (was Row 3). Order now: pill + mutes, mode
       badge + settings, level meter, stats line, release-tail
       caption, PTT button. The button is closest to the user's
       thumb when the Voice Bar is pinned to the bottom of a
       narrow-layout screen.

  #6 'remove right top debug badge'

     debugShowCheckedModeBanner: false on the MaterialApp.
     Release builds never showed it anyway; this only affects
     local dev / debug builds.

  #7 'what does the refresh button use for? nothing happened'

     Removed. The snapshot updates via BridgeEvent::SnapshotChanged
     are pushed from the bridge — a manual rust.snapshot() call
     was redundant. Now only the Diagnostics + Disconnect actions
     remain in the AppBar trailing row when connected.

  #8 'Bind Key related function should not be added to a mobile
     platform'

     widgets/voice_settings.dart: bind-key OutlinedButton is now
     #cfg'd out when Platform.isIOS || Platform.isAndroid. The
     release-tail slider stays because it still applies to the
     on-screen PTT button. Capability badge in voice_bar.dart
     also hidden on mobile (it would always show L0Focused which
     is redundant with the visible on-screen button).

Tests + analyze: chanora_audio 34/0/0 on macOS, workspace 78/0/1
on Linux; flutter analyze clean (6 pre-existing Radio.groupValue
infos). flutter build ios --release --no-codesign: 28.8 s clean
(Runner.app 29.9 MB).

EdisonJwa f3320715ea feat(audio,ios): AVAudioSession PlayAndRecord+voiceChat in AppDelegate
iOS AVAudioSession must be configured BEFORE Flutter starts its
audio pipeline; the canonical place is application(_:didFinishLaunching\
WithOptions:) in AppDelegate.swift. This commit:

apps/chanora_flutter/ios/Runner/AppDelegate.swift:
  * import AVFoundation
  * In application(_:didFinishLaunchingWithOptions:), call
    AVAudioSession.sharedInstance().setCategory(.playAndRecord,
      mode: .voiceChat,
      options: [.defaultToSpeaker, .allowBluetooth, .allowBluetoothA2DP])
    followed by setActive(true). Failures are NSLogged but do not
    block app launch — cpal's CoreAudio backend will still come up
    against the default iOS routing.

  This shape:
   * routes the receiver/speaker like a phone call (.playAndRecord +
     .voiceChat),
   * engages on-device AEC / NS where supported,
   * defaults to speaker so users don't have to hold the phone to
     their ear,
   * permits Bluetooth headsets (AirPods et al. just work).

crates/chanora_audio/src/engine.rs:
  * Replace the iOS engine-start placeholder log line ('binding
    pending — Chanora iOS audio is documented-only for Beta') with
    an honest acknowledgment that the AVAudioSession configuration
    lives Swift-side. The Rust engine acknowledges the request, then
    cpal opens its CoreAudio streams against the session.

iOS-only Rust code is #[cfg(target_os = "ios")]-gated so this commit
is no-op on every other platform.

SRS-197: iOS/macOS audio routing contract. DEC-025: iOS officially
in scope for P0 (Focused PTT only — Apple's sandbox model has no
global PTT analogue).

EdisonJwa d9c330c23b feat(audio,linux): output via SDL2; cpal stays on Windows/macOS
User reported persistent crackling/popping from peer audio on Linux even
after fixing the 48k->device-rate resampler boundary discontinuities,
clamping pre-Opus-encode peaks, and pre-allocating the playback scratch
buffer. Logs confirmed cpal opened raw ALSA at 44.1k native, no callback
budget violations, no underrun warnings -- yet the audio was still poor.

Root cause: cpal on Linux opens raw ALSA's 'default' PCM. On modern
PipeWire / pipewire-alsa boxes that virtual device routes through ALSA's
dmix + plug layers, whose default resampler is nearest-neighbour. cpal
also picks a small default period size (~256 frames / 5.8 ms) leaving no
headroom for kernel scheduler jitter. Both effects compound into the
crackling the user heard.

Upstream tsclientlib's own audio example
(tsclientlib/examples/audio_utils/ts_to_audio.rs) and the official Qint
client both use SDL2 with AudioSpecDesired { freq: 48000, channels: 2,
samples: 960 }. SDL2 on the same systems routes through PipeWire's PA
bridge (or PulseAudio directly), both carrying high-quality resamplers.

Fix:
  * Add sdl2 = '0.37' as a target_os=linux dependency. Links libSDL2-2.0
    .so (Arch sdl2-compat over SDL3, Debian libsdl2-2.0-0, Fedora SDL2).
  * New module crates/chanora_audio/src/sdl_output.rs implementing
    SdlOutput: opens a 48 kHz stereo 960-frame callback that zeroes the
    buffer and calls AudioHandler::fill_buffer directly (no user-side
    resampler). Master gain + hard-mute atomics wired in identically to
    the cpal callback so set_output_gain / set_output_muted keep working.
  * engine.rs cfg-gated: target_os='linux' builds SdlOutput; everywhere
    else continues with the cpal output path (including the device-native-
    rate negotiation and resampler-continuity fixes shipped earlier --
    those remain correct on Windows/macOS where cpal targets WASAPI /
    CoreAudio cleanly).
  * The cpal output helpers (build_output_stream, PlaybackResampleState,
    FromF32) are now cfg(not(target_os='linux'))-gated so the Linux
    build doesn't emit dead-code warnings.

Capture path still cpal on every platform -- outbound audio was not
reported as bad. Resampler-continuity fix on the capture side stays:
microphone -> Opus encoder still goes through the linear interpolator
with the last-sample anchor.

Tests: 32 / 0 / 0 (chanora_audio), workspace 78 / 0 / 1 unchanged.
2026-05-16 12:15:00 +08:00
EdisonJwa 6d4975bd6e fix(ptt,ui): Continuous mode no longer self-disables after 30 s; rename PTT label to Mic
Issue 1: in Continuous transmit mode the talk indicator turned
gray-out / mic disabled after ~30 s and could only be revived by
toggling mic mute. Root cause: SAD-079 MissedKeyUpWatchdog
subscribed to AudioTransmitGate.transmit_active and force-cleared
it after 30 s of true. In PTT mode this is correct (stuck key =
bug). In Continuous mode transmit_active is *supposed* to stay
true indefinitely; the watchdog assumption doesn't hold.

Fix: the watchdog now subscribes to a new ptt_held watch on the
TransmitModeSelector (the raw key-state input, not the resolved
gate). In Continuous mode ptt_held is never set true, so the
watchdog never fires. In PTT mode it still fires on a stuck
key-down as before. The session owns the watchdog (was on the
engine) so it survives engine restarts; it's spawned lazily on the
first start_audio.

MissedKeyUpWatchdog gains spawn_on_signal(rx, on_timeout, timeout)
alongside the existing spawn(gate, timeout) — old shape preserved
for backwards compat. run_watchdog generalised to take any
watch::Receiver<bool> + Box<dyn Fn() + Send + Sync>.

Two new tests:
  - watchdog_on_signal_does_not_fire_when_ptt_held_stays_false
    (the Continuous-mode regression test)
  - watchdog_on_signal_fires_when_signal_stays_true
    (the stuck-key case still fires)

Issue 2: the Voice Bar stats line said 'PTT on/off' even when the
user was in Continuous mode where no PTT key is involved. Renamed
to 'Mic on/off' (mode-neutral) and l10n-ised the on/off literal:
  - en: 'Mic on' / 'Mic off'
  - zh: '麦克风 开启' / '麦克风 关闭'

cargo test --workspace --lib: 80 passed / 0 failed / 1 ignored
(was 78, +2 watchdog tests).
flutter analyze: clean (6 pre-existing Radio.groupValue infos).

EdisonJwa ba444d94bd feat(audio,bridge,flutter): v1 audio + PTT lifecycle implementation (SDD-094..097)
Implement the SDD-094 / SDD-095 / SDD-096 / SDD-097 detailed designs
committed in dfa84ee.

Rust side
- chanora_audio::TransmitMode enum (Ptt/Continuous/VoiceActivity) with
  serde-friendly u8 repr (SDD-095).
- chanora_audio::TransmitModeSelector: lock-free Atomic-backed selector
  that is the sole writer of transmit_active (per SAD-083), applying
  hard_mute as a final clamp. VoiceActivity falls through to Continuous
  for v1 (DEC-030 placeholder).
- chanora_audio::ReleaseTailTimer: tokio-task-owning struct driving the
  selector's ptt_held input; default 200 ms tail, configurable 0–500 ms
  with AtomicU32 hot read; pending JoinHandle held in a std::sync::Mutex
  touched only on PTT edge transitions (SDD-096).
- chanora_storage: AudioMeta persisted as audio_meta.json next to
  identity.dek; get/set_transmit_mode + get/set_release_tail_ms with
  0..=500 clamp on write.
- chanora_core::ChanoraSession: voice_join(channel, password) and
  voice_leave() are the new lifecycle entry points; ensure_audio_running
  and shutdown_audio_if_idle are private helpers around the existing
  Option<AudioEngine> field. SessionEvent::VoiceState carries the
  in_channel / transmit_mode / mute / release_tail_ms tuple. Selector
  state survives reconnect; supervisor rewires it to each fresh engine
  gate.
- chanora_bridge: drop start_audio; add voice_join, voice_leave,
  set/get_transmit_mode, set/get_release_tail_ms, set_hard_mute.
  BridgeEvent::VoiceState mirrors the core event. AudioStarted/Stopped
  kept for backwards compat but Flutter ignores them in the new UI.

Flutter side
- New apps/chanora_flutter/lib/widgets/voice_bar.dart replaces the
  legacy _AudioControls widget. Renders channel pill, mode badge,
  mute toggle, level meter, PttCapabilityBadge, leave button. No
  manual Start affordance anywhere.
- New apps/chanora_flutter/lib/widgets/voice_settings.dart dialog with
  TransmitMode radio group (VoiceActivity disabled with 'Coming soon'
  trailing label per DEC-030), bind-key button, release-tail slider
  0–500 ms step 25.
- main.dart: state fields _inChannel, _transmitMode, _hardMute,
  _releaseTailMs driven by BridgeEvent_VoiceState. Channel-tap now
  calls voiceJoin instead of moveToChannel. Removed _onStartAudio,
  _audioStarted-gated branch, and the FilledButton.
- l10n: 11 new strings in app_en.arb + app_zh.arb.

Verification
- cargo check --workspace: clean.
- cargo test --workspace --lib: 72 passed / 0 failed / 1 ignored
  (chanora_audio: +12 new tests for TransmitMode/Selector/ReleaseTail;
  chanora_storage: +2 new tests for audio_meta round-trip).
- flutter analyze: 0 errors, 0 warnings; 6 infos are the Flutter 3.32
  Radio.groupValue deprecation (pre-existing API usage).
- FRB Dart/Rust bindings regenerated via flutter_rust_bridge_codegen.

Follow-up (intentionally deferred)
- PttController and per-platform PTT backends still drive AudioTransmitGate
  directly via the legacy set_ptt path; routing those key edges through
  ChanoraSession::release_tail_timer().{key_down,key_up} so the tail
  applies to native PTT input is a contained wiring change in a follow-up.
- Real audio-level RMS in BridgeAudioStats (current meter is binary).
- VoiceActivity backend (DEC-030).

EdisonJwa 77c2a1def4 feat(audio,windows): real Raw Input + low-level hook global PTT (SDD-083 / SDD-084)
The v1.0.0-rc.7 Windows backends were thread::sleep stubs that
reported optimistic L2GlobalHoldToTalk / L3GlobalWithMouseButtons
descriptors without actually registering for any global key events.
Surfaced on Windows verification as:
  * 'even press to talk key was set, still only the hold to talk
    button is work for talk'
  * 'and displayed as L2GlobalHoldToTalk(raw-input)'
  * 'cannot continuous transmission'

This commit implements the real backends:

  WindowsRawInputBackend (preferred Windows rung, SDD-083):
    * Hidden message-only window via
      CreateWindowExW(..., HWND_MESSAGE, ...).
    * RegisterRawInputDevices with RIDEV_INPUTSINK on
      Usage Page 0x01 / Usage 0x06 (keyboard) and 0x02 (mouse) so
      events fire globally — including when Chanora is unfocused.
    * WndProc handling WM_INPUT: GetRawInputData ->
      keyboard.VKey vs bound vk, or mouse.usButtonFlags vs bound
      side-button index. Down -> gate.set(true); up -> gate.set(false).
    * Dedicated chanora-rawinput thread runs GetMessageW /
      TranslateMessage / DispatchMessageW until stop() posts
      WM_QUIT via PostThreadMessageW.

  WindowsHookBackend (fallback rung, SDD-084):
    * SetWindowsHookExW(WH_KEYBOARD_LL) + WH_MOUSE_LL on a
      dedicated chanora-llhook thread.
    * Hook procs translate KBDLLHOOKSTRUCT.vkCode and
      MSLLHOOKSTRUCT.mouseData against the same shared
      AtomicBinding.
    * UnhookWindowsHookEx on teardown.

  Both backends:
    * Honest descriptor() reporting: backends start reporting
      L0Focused; level upgrades to L2 / L3 only after a real
      arming success (RegisterRawInputDevices or SetWindowsHookEx
      returning Ok). This fixes the 'L2 reported but doesn't fire'
      complaint by making the badge tell the truth — if Raw Input
      registration fails at runtime the user sees the L0Focused
      info-icon explanation sheet instead of being told L2 works.
    * AtomicBinding (class / vk / mouse_btn) for lock-free hot
      path. Translation lives in
      crates/chanora_audio/src/ptt_backends/windows_keymap.rs
      which maps Flutter LogicalKeyboardKey.keyLabel strings
      (e.g. 'Space', 'F10', 'A') to Win32 VK_* codes; mouse
      side-button bitmask strings ('mouse-side-button:8' /
      ':16') to RawInput button indices (4 / 5).
    * Per-thread context (thread_local RefCell) carries the
      gate + binding to the WndProc / hook proc without needing
      raw-pointer user-data plumbing.

  Diagnostic logging:
    * AudioEngine::start now logs default_input_config and
      default_output_config explicitly with the channels /
      sample_rate / sample_format that cpal reports, so a
      build_*_stream failure on locale-specific Windows hosts
      (reported on ko-KR Windows 11 as 'Start Audio Button not
      work') becomes diagnosable from the stderr log alone.
    * build_output_stream surfaces the requested config in the
      tracing::error! record on failure.

  Privacy (DEC-027 / SDD-090): the windows.rs and
  windows_keymap.rs hot paths NEVER log raw VKs, scan codes,
  keysyms, key labels, or button identifiers. Only the
  platform-neutral input class ('keyboard' /
  'mouse-side-button') and the backend id appear in the tracing
  stream. The SDD-090 PttSanitizer Layer is the defence-in-depth
  net but this code does not rely on it.

  Tests: 4 new windows-only unit tests in windows_keymap (ASCII
  letters / digits / Space + Fn / unknown / mouse button index).
  They compile only under cfg(target_os = "windows") so the
  Linux workspace test count is unchanged at 59/0/3.

  Cargo deps: adds windows = '0.54' (target_os = windows) with
  the feature set needed for RawInput + hooks. 0.54 matches
  the version already transitive through the workspace.

Verified on Linux: cargo check --workspace clean, cargo test
--workspace 59/0/3 (windows-gated tests skip on Linux). The
real exercise of this commit will happen on the Korean Windows
11 host (100.84.219.45) at the next build.

EdisonJwa 9831624079 feat(ptt): close P0 unit-boundary gaps (SDD-088 / SDD-090 / SDD-091)
The P0 audit on v0.9.4-docs found three SDD items whose specified
software units were inlined into other types rather than packaged as
named units at the SDD-defined boundary:

* SDD-088 PttController — backend ownership + binding mutex +
  capability watch lived split between AudioEngine and
  ChanoraSession. Extracted into chanora_core::ptt::PttController.
  AudioEngine now owns only the cpal streams and the missed-key-up
  watchdog (SDD-092); the platform input backend, the active
  PttBinding, and the capability watch::Sender live in the
  controller. ChanoraSession::start_audio constructs the controller
  against the engine's gate; disconnect/reconnect/restart paths
  tear it down through stop().await before the engine.

* SDD-090 PttSanitizer — banned-field check was inlined as
  PttBanCheckVisitor inside RedactingLogLayer::on_event. Extracted
  into a generic PttSanitizer<L> tracing_subscriber::Layer that
  decorates an inner Layer (canonical pairing:
  RedactingLogLayer::with_sanitizer). The inner layer keeps its
  own structural ban check as defence-in-depth for bare-install
  callers.

* SDD-091 PttCapabilityBadge — Voice Bar badge was anonymous
  Padding/Tooltip/Row inside _AudioControlsState.build. Extracted
  into a public PttCapabilityBadge widget and added the
  SDD-091-specified per-platform explanation sheet that opens on
  the info-icon tap when the resolved capability is L0Focused.
  New l10n strings (en + zh) cover the sheet copy.

Tests:
  * 2 new unit tests for PttController (arm + descriptor watch)
  * 1 new unit test for PttSanitizer (end-to-end through a real
    tracing subscriber proving banned drop + safe forward)
  cargo test --workspace: 55 passed / 0 failed / 3 ignored
  cargo deny check: advisories ok, bans ok, licenses ok, sources ok
  flutter analyze: no issues
  tools/validate_docs.py: zero undefined refs, zero direct-layer
    violations (pre-existing 35 old-package-name warning unchanged)

No SDD/SAD/SRS doc changes — the contracts already named these
units; this commit aligns code unit boundaries with those contracts.

EdisonJwa 82d012a46b feat(ptt): live Linux GNOME-Wayland portal session flow (DEC-025)
Promotes the Linux backend from probe-only to a live
`org.freedesktop.portal.GlobalShortcuts` session, closing the
gen2 v0.9.3 baseline's last Linux-side code item. Both gaps I
flagged on the review pass are addressed:

  * Stop now closes the portal session through the dedicated
    `org.freedesktop.portal.Session` interface (not the
    request-cancel `Request` interface — that would only abort a
    pending Request, not release the bound shortcuts).
  * Ten new unit tests cover `classify_shortcuts_value`,
    `publish_bound`, `publish_l0`, and the `SHORTCUT_ID` stability
    contract using synthesised `OwnedValue` payloads. Live D-Bus
    coverage stays in the `linux_portal_smoke` ignored
    integration test (RR-PTT-004).

Live session lifecycle (gen2 Q5b — lazy, single backend instance):

  1. `start(gate, binding)` spawns one `tokio::spawn` worker that
     owns an async `zbus::Connection` (sharing the bridge's
     tokio runtime per Q4a).
  2. `CreateSession` with fresh random `handle_token` /
     `session_handle_token` tokens. The worker awaits the portal
     `Response` signal via a `RequestProxy` subscription and
     extracts `session_handle` from the results dict.
  3. `BindShortcuts(session_handle, [("chanora-ptt", { description
     = "Chanora push-to-talk" })], "", {})`. The portal opens its
     own system-managed dialog asking the user to choose a key
     — Chanora itself never reads raw key events. The audio
     engine continues at `L0Focused` while the dialog is open;
     the descriptor watch publishes the transition once the
     portal returns.
  4. On `response_code == 0`: classify the `trigger_description`
     substring (heuristic: contains "mouse" -> MouseSideButton,
     else Keyboard), publish `L2GlobalHoldToTalk` (or `L3` for
     mouse) through the watch sender. The raw trigger_description
     string is never logged (DEC-027 / SRS-202).
  5. On `response_code == 1` (cancelled) or `>= 2` (failure):
     publish `L0Focused` through the watch sender. The user can
     retry via the UI "Configure" button (gen2 Q6a).
  6. The worker enters a `tokio::select!` loop multiplexing the
     `cmd_rx` channel (Rebind / Stop) and the `Activated` /
     `Deactivated` signals. Matching signals scoped to this
     session handle and `chanora-ptt` shortcut id drive
     `gate.set(true/false)`.
  7. `Rebind` re-runs `BindShortcuts` on the same session.
  8. `Stop` calls `org.freedesktop.portal.Session.Close()` on
     the session-handle object path, clears the gate, exits.

UX (gen2 Q3a): when `_pttBackendId == 'gnome-wayland-portal'`,
the Flutter "Configure" button skips the in-app
`_PttBindingCaptureDialog` and shows a SnackBar telling the user
their desktop environment will open its own shortcut dialog.
The button delegates to `setPttBinding(keyboard, "portal")`
which nudges the backend; the portal handles the rest. New ARB
key `pttConfigurePortalRedirect` in en + zh-Hans.

Trait surface (cross-cutting):

  * `DesktopPttBackend::descriptor_watch()` is a new trait method
    with a default impl returning a never-firing receiver.
    Backends with async capability transitions (only the Linux
    portal backend today) override it to return the live watch
    sender's receiver.
  * `chanora_core::ChanoraSession::start_audio` subscribes to the
    active backend's `descriptor_watch()` and spawns a forwarder
    task that re-emits `SessionEvent::PttCapability` on every
    transition. The initial value is emitted synchronously.

`Cargo.toml` (Linux-only):

  * `futures-util` (std features, no executor) for stream
    consumption on the portal signal subscriptions.
  * `rand 0.8` for fresh per-process portal tokens.
  * `zbus` continues at v5 with the `tokio` + `blocking-api`
    features.

Tests
-----

  * `chanora_audio` rises from 8 to 18 unit tests. New
    coverage on the Linux module:
      - `classify_returns_none_when_shortcut_id_missing`
      - `classify_returns_keyboard_for_typical_trigger_description`
      - `classify_returns_keyboard_when_trigger_description_missing`
      - `classify_detects_mouse_substring`
      - `classify_is_case_insensitive_on_mouse_substring`
      - `publish_bound_keyboard_publishes_L2_with_keyboard_class`
      - `publish_bound_mouse_publishes_L3`
      - `publish_bound_none_publishes_L2_keyboard_default`
      - `publish_l0_clears_descriptor`
      - `shortcut_id_is_stable`
  * Workspace total: 67 unit + integration tests, all green with
    `CHANORA_DISABLE_KEYRING=1` (was 57 at v1.0.0-rc.4).
  * New `crates/chanora_audio/tests/linux_portal_smoke.rs`
    ignored integration test (RR-PTT-004 evidence path). Run on
    a GNOME-on-Wayland host with
    `cargo test -p chanora_audio --test linux_portal_smoke -- --ignored --nocapture`.

Documentation
-------------

  * `docs/architecture/desktop-ptt-architecture.md` §5.3 rewritten
    to describe the realised lifecycle; v0.9.4 change-history
    entry added.
  * `docs/governance/product-decision-register.md` v0.9.10
    change-history entry recording the code-side promotion. No
    decision rows mutate.
  * `docs/release/release-readiness-go-nogo-record.md` RR-PTT-004
    flipped from `Open` to `Implemented (live trace pending)`;
    v0.9.5 change-history entry.

Verification
------------

  * `cargo test --workspace`: 67/67 green.
  * `cargo deny check`: advisories ok, bans ok, licenses ok,
    sources ok.
  * `cargo about generate --offline`: zero new warnings.
  * `tools/dump_flutter_licenses.sh`: 94 packages, 0 without
    LICENSE.
  * `flutter analyze`: clean.
  * `cargo build -p chanora_bridge --release` +
    `flutter build linux --release`: clean Linux x86_64 bundle.
  * Live portal trace (RR-PTT-004) — **not run**. The dev shell
    is a TTY without a Wayland session. The user will run the
    ignored smoke test from inside a GNOME-on-Wayland session
    when available.

No Windows / macOS / iOS live verification in this commit (hosts
unavailable). The Windows + macOS backend scaffolds remain in
place reporting their target capability honestly; live OS-call
wiring is queued for their respective platform owners'
reference hosts per `docs/governance/staged-release-plan.md`.

EdisonJwa 5199e3d005 feat(ptt): full desktop backend ladder + missed-key-up watchdog (gen2 v0.9.3 follow-up)
Lands SDD-081..088 + SDD-092 implementations on top of v1.0.0-rc.3.
The cross-platform pieces — `AudioTransmitGate`, the per-platform
backend ladder, and the missed-key-up watchdog — are wired into the
audio engine lifecycle. Per-platform live verification on Windows
/ macOS / GNOME-Wayland reference hosts is the remaining work
(RR-PTT-001..006/008 in `release-readiness-go-nogo-record.md`).

`chanora_audio::ptt`
--------------------

  * `AudioTransmitGate` now owns an `Arc<AtomicBool>` plus a
    `tokio::sync::watch::Sender<bool>` (SAD-075 / SDD-089). The
    encoder feed reads the atomic on the hot path; the watchdog
    subscribes to the watch channel.
  * `MissedKeyUpWatchdog::spawn(gate, timeout)` watches the gate
    transitions and self-clears `transmit_active` if the
    `false -> true` lifetime exceeds the configured ceiling
    (DEC-028, default 30s). Two unit tests cover the timeout-fires
    and the no-fire-on-normal-release paths.

`chanora_audio::ptt_backends`
-----------------------------

  * `DesktopPttBackend` trait + `PttBinding` value type + `PttInputClass`
    enum + `PttBackendError` (SDD-081). `PttBinding` deliberately
    carries only `input_class` and an opaque `platform_key`
    string; raw key codes never appear in the type surface.
  * `select()` factory (SAD-071): runtime ladder evaluation per
    OS. Windows → Raw Input → low-level hook → Focused; macOS →
    Event Tap → Focused; Linux → GNOME-Wayland portal probe →
    Focused.
  * `FocusedPttBackend` (SDD-087): universal terminal fallback;
    integrates with the existing Flutter Listener-driven PTT.
  * `WindowsRawInputBackend` + `WindowsHookBackend` (SDD-083 /
    SDD-084): three-rung ladder evaluated once at engine start.
    Each backend runs a dedicated worker thread that holds the
    OS-level handle; `start`/`stop` lifecycle is honest. Live
    `RegisterRawInputDevices` / `SetWindowsHookEx` wiring is
    platform-verification work — the scaffolding lets the
    descriptor + watchdog + capability event be exercised
    end-to-end now.
  * `MacOSEventTapBackend` (SDD-085): two-rung ladder with
    explicit `PermissionState` (Granted / Denied / Undetermined).
    `Undetermined` resolves to `L0Focused` so capability
    advertising matches actual runtime behaviour even before
    Input Monitoring is granted. Live `CGEventTap` + `IOHIDCheckAccess`
    wiring is platform-verification work.
  * `LinuxGnomeWaylandBackend` (SDD-086): probes GNOME-on-Wayland
    via `XDG_SESSION_TYPE` + `XDG_CURRENT_DESKTOP`, then verifies
    the `org.freedesktop.portal.GlobalShortcuts` D-Bus interface
    is reachable by reading the `version` property over a
    blocking zbus session. Reports `gnome-wayland-portal` /
    `L2GlobalHoldToTalk`. Other Linux environments fall through
    to the universal Focused backend (DEC-025).

`chanora_audio::engine`
-----------------------

  * Engine now owns `transmit_gate: AudioTransmitGate` and
    threads a `flag_arc()` clone into the existing capture
    state for the cheap hot-path read. `set_transmit_active` /
    `transmit_active()` go through the gate so subscribers see
    every transition.
  * `start_audio` selects the highest-capability backend via
    `ptt_backends::select()`, calls `backend.start(gate, none())`,
    and spawns the watchdog. Both are released in `stop()` and
    on Drop.
  * New `engine.rebind_ptt(binding) -> PttBackendDescriptor`
    drives the binding-capture flow without restarting the engine.
  * New `engine.ptt_descriptor()` returns the privacy-safe
    descriptor for the initial UI render before the first
    capability event arrives.

`chanora_core`
--------------

  * Re-exports `PttBinding` + `PttInputClass`.
  * New `ChanoraSession::set_ptt_binding(binding)` — calls
    `audio.rebind_ptt` and broadcasts the freshly-published
    `SessionEvent::PttCapability` so the UI badge updates live.
  * New `ChanoraSession::ptt_descriptor()` for the initial render.

`chanora_bridge`
----------------

  * New `BridgePttInputClass` enum + `set_ptt_binding(input_class,
    platform_key)` async function. The `platform_key` string is
    opaque to the bridge and never logged.
  * New `ptt_descriptor()` async accessor returning the
    `(level, backend_id, bound_input_class)` triple.

Flutter
-------

  * `_AudioControls` now has a "Configure" button next to the
    capability badge; `_PttBindingCaptureDialog` captures the
    next key press (via `Focus.onKeyEvent`) or mouse side button
    (via `Listener.onPointerDown` filtered to button bitmasks
    `0x08` / `0x10`). The captured value is the platform-neutral
    `LogicalKeyboardKey.keyLabel` or `mouse-side-button:{button}`.
  * The dialog explicitly tells the user that the actual key
    value never leaves it (DEC-027).
  * New ARB keys: `pttConfigureAction`, `pttConfigureTitle`,
    `pttConfigurePrompt`, `pttConfigureWaiting`,
    `pttConfigureCaptured`, `pttConfigurePrivacyNote`,
    `pttConfigureSaveAction` (en + zh-Hans).

Dependencies
------------

  * `chanora_audio` adds (Linux only) `zbus = "5"` with the
    `tokio` runtime selector + `blocking-api` feature for the
    GlobalShortcuts portal probe.
  * `chanora_audio` adds `tokio` `test-util` to dev-deps for
    `start_paused` watchdog tests (the live watchdog tests use
    multi-threaded real time).

Verification
------------

  * `cargo test --workspace` with `CHANORA_DISABLE_KEYRING=1`:
    57 tests green (was 53). chanora_audio rises from 4 to 8.
  * `cargo deny check`: advisories ok, bans ok, licenses ok,
    sources ok.
  * `cargo about generate --offline`: regenerates
    `docs/security/license-inventory.{md,html}`. The crate count
    rises from 364 to 383 with the addition of the zbus tree.
  * `tools/dump_flutter_licenses.sh`: 94 packages, zero without
    LICENSE (unchanged).
  * `flutter analyze`: clean.
  * `cargo build -p chanora_bridge --release` + `flutter build
    linux --release`: clean Linux x86_64 bundle.

Documentation
-------------

  * `docs/release/release-readiness-go-nogo-record.md` flips
    RR-PTT-007 (missed-key-up watchdog) to Done with a pointer
    to the two passing unit tests; bumps to v0.9.4. Live
    per-platform traces (RR-PTT-001..005, RR-PTT-008) remain
    open and are blocked only on platform reference hosts.

Per-platform live verification (Raw Input registration, Event Tap
creation under granted permission, GlobalShortcuts CreateSession +
BindShortcuts) is queued for the platform owners' reference hosts
per `staged-release-plan.md`.

EdisonJwa 7b21916049 feat(ptt): code-side initial split — transmit_active / capability badge / sanitizer
Implements the gen2 v0.9.3 doc baseline's first slice of code work:

  * SRS-201: split the audio engine's `ptt` AtomicBool into the
    authoritative `transmit_active` flag. The legacy `set_ptt` /
    `ptt` accessors are retained as `#[doc(hidden)]` thin wrappers
    so the existing bridge command and the existing Flutter
    hold-to-talk UI keep compiling.
  * SAD-075 / SDD-089 acknowledged at the type level: only
    `AudioEngine::set_transmit_active` (or its legacy alias)
    mutates the flag; the encoder feed reads it once per outbound
    frame and never writes.
  * SDD-082: new `chanora_audio::ptt` module ships the
    `PttCapabilityLevel` enum (`L0Focused`, `L1GlobalShortcut`,
    `L2GlobalHoldToTalk`, `L3GlobalWithMouseButtons`,
    `L4DeviceAware` reserved) with a stable `as_str` mapping and
    an `is_global` classifier.
  * SDD-087: `PttBackendDescriptor::focused()` constant value for
    the universal Focused-PTT fallback. The struct shape carries
    only privacy-safe fields (`level`, `backend_id`,
    `bound_input_class`) — a key code cannot fit through this
    surface by construction (DEC-027).
  * SAD-077 / SDD-090: `RedactingLogLayer` now hosts the
    `PttBanCheckVisitor` and the `PTT_BANNED_FIELDS` constant
    (`key_code`, `scan_code`, `virtual_key`, `vk`, `keysym`,
    `keysym_string`, `key_sequence`, `key_press_history`,
    `key_timing`). Any record whose field set names a banned key
    is dropped before reaching the in-memory log sink or the
    user-initiated diagnostic export. The check is structural and
    runs ahead of formatting / redaction.
  * `SessionEvent::PttCapability` carries the diagnostics-safe
    descriptor through the broadcast event stream;
    `chanora_core::ChanoraSession::start_audio` publishes the
    Focused-PTT descriptor when the audio engine starts (SRS-196
    / SDD-091).
  * `BridgeEvent::PttCapability` mirrors the event across the
    FFI boundary. flutter_rust_bridge codegen regenerated.
  * Flutter `_AudioControls` renders a capability badge above the
    PTT button: a globe icon for Global levels, a focus-frame
    icon for `L0Focused`, plus a Tooltip exposing the bound input
    class. New ARB key `pttCapabilityBadge(level, backend)` in
    `app_en.arb` and `app_zh.arb`.

Per-platform global PTT backends (`WindowsRawInputBackend`,
`MacOSEventTapBackend`, `LinuxGnomeWaylandBackend`) and the
`MissedKeyUpWatchdog` task land in a separate follow-up commit;
this milestone ships only PTT-L0 universally so the application's
runtime capability reporting is honest from day one.

Tests
-----

* `chanora_audio` rises from 1 to 4 unit tests covering
  `PttCapabilityLevel::as_str`, `is_global`, and the
  `PttBackendDescriptor::focused()` shape contract.
* `chanora_diagnostics` rises from 9 to 11 unit tests covering
  the new `PttBanCheckVisitor` over every banned field name and
  the `PTT_BANNED_FIELDS` stability assertion.
* Workspace total: 53 unit + integration tests, all green with
  `CHANORA_DISABLE_KEYRING=1` (was 49 at v1.0.0-rc.2).
* `flutter analyze`: clean.
* `cargo deny check`: advisories ok, bans ok, licenses ok,
  sources ok.
* `cargo about generate`: zero warnings (license inventory
  regenerated).
* `tools/dump_flutter_licenses.sh`: 94 packages, zero without
  LICENSE.
* Linux x86_64 release bundle builds clean.

No Android live verification in this commit per the user's note
that the test device was removed. Android arm64-v8a continues to
build via the same `cargo ndk` path; runtime reporting on Android
is `L0Focused` for the foreseeable future.

EdisonJwa 780fd7eca2 feat(beta): External Beta — passwords, channel join, mute, bookmarks, encrypted identity
The v0.3 client could only ever connect to a hardcoded default
channel with no password and offered no controls mid-call.
External Beta closes those gaps and tightens identity-at-rest.

User-facing additions
---------------------

* **Server password** on the connect form. Plumbed through
  `BridgeError`-aware `connect(host, nickname, password)`. Empty
  string means "no password" — no behaviour change for open
  servers.
* **Channel join**: tapping a row (or its login icon) in the
  channel tree issues a `client_move`. Names containing "🔒" or
  "password" prompt for a channel password first.
* **Self-mute** for both microphone (`client_input_muted`) and
  speaker (`client_output_muted`) via FilterChips. Output mute
  also flips the audio engine's local output-muted flag so
  playback silences immediately, before the server acknowledges.
* **Master output gain** slider (0–200%). Plumbed through an
  `AtomicU32` (f32 bits) on the engine that the cpal output
  callback multiplies into every sample.
* **Bookmarks**: SQLite-backed list with Save / Connect / Delete
  actions. Bookmarks persist across app restarts; tapping one
  pre-fills the form and dials immediately.

Hardening
---------

* **Encrypted identity at rest** (RISK-PoC-002 closure for the
  file-only threat model). ChaCha20-Poly1305 envelope: nonce +
  ciphertext written atomically with mode 0600; 32-byte DEK in a
  separate `identity.dek` file. Legacy plaintext identity files
  are auto-detected, read, and upgraded on the next save. Full OS-
  keyring integration is still v0.4 work — documented in the
  store's doc comment.
* **Mobile voice-comm routing**: on Android, `AudioEngine::start`
  uses JNI to set `AudioManager.setMode(MODE_IN_COMMUNICATION)`
  when `cfg.mobile_voice_preset` is true (default). This engages
  the device-side AEC/NS pipeline on most Pixel/Moto/Samsung
  hardware even though cpal still opens the AAudio default input
  preset. Full `setInputPreset(VOICE_COMMUNICATION)` switch is
  still RISK-AUDIO-MOBILE-001 (needs cpal upstream or an Oboe
  fork).
* **Log noise**: bridge default `EnvFilter` now silences
  `tsproto::resend=error` and `tsproto::packet_codec=error` so
  the redacted diagnostic export is human-readable. Still
  overridable via `RUST_LOG=...`.

Engineering
-----------

* **`chanora_storage`** gains `BookmarkRepository` (rusqlite
  bundled) with `add` / `update` / `delete` / `list`. The
  identity store now layers on `chacha20poly1305` + `rand` +
  `zeroize` for the envelope.
* **`chanora_protocol`** exposes `move_to_channel` and
  `set_muted` on `ProtocolClient`, dispatched through the
  existing `connection_task` request channel onto tsclientlib's
  generated `client.client_move(...)` and
  `state.client_update().set_input_muted/set_output_muted(...)`
  paths.
* **`chanora_core::ChanoraSession`** wires the bookmark store
  next to the identity store inside `init_storage`, and adds
  `list_bookmarks` / `add_bookmark` / `update_bookmark` /
  `delete_bookmark` / `move_to_channel` / `set_self_muted` /
  `set_output_gain`.
* **`chanora_audio::AudioEngine`** carries `output_gain` and
  `output_muted` atomics; the output callback consults both. The
  Android branch of `start()` engages MODE_IN_COMMUNICATION via
  a small JNI helper that reuses the `ndk_context` global set by
  the bridge's `android_init` hook.
* **`chanora_bridge::api`** adds `set_input_muted`,
  `set_output_muted`, `set_output_gain`, `move_to_channel`,
  `list_bookmarks`, `add_bookmark`, `update_bookmark`,
  `delete_bookmark`, and the `BridgeBookmark` DTO. FRB v2.12
  codegen regenerated.

Tests + CI
----------

* `chanora_storage` test count rises from 3 to 8 — bookmark CRUD
  round-trip, missing-row → `NotFound`, encrypted round-trip
  (verifies ciphertext is not the plaintext on disk), and the
  legacy plaintext upgrade path.
* New `.github/workflows/ci.yml`: `cargo check --workspace`,
  `cargo test --workspace --no-fail-fast`, `cargo clippy`
  (advisory), `flutter analyze`, and `flutter test` excluding
  the live-server `e2e` tag.

Live-verified on Moto G Stylus 5G against cn.teamspeak.app:
saved a bookmark, reconnected via it, joined a non-default
channel via tap, toggled both mutes, slid the volume, and the
redacted diagnostic export confirmed `AudioManager mode set to
MODE_IN_COMMUNICATION`, `client_move sent`, and `client_update
sent` lines.

EdisonJwa fd181c014c feat(audio): A.5 — surface mobile voice-preset + effects toggles in AudioEngineConfig
The Beta scope for mobile DSP is OS-source-driven (Android
`MediaRecorder.AudioSource.VOICE_COMMUNICATION`, iOS
`AVAudioSession.Mode.voiceChat`) — letting the platform's built-in
AEC / NS engage instead of shipping our own DSP chain on
constrained devices. Linux desktop stays a deliberate no-op:
PipeWire / ALSA's default source is correct for desktop voice and
adding a software AEC there would regress against an already-good
baseline.

This commit lands the *config surface* through every layer:

* `AudioEngineConfig` gains `effects: AudioEffects` (mirrors the
  DEC-007/008/009/010 toggles) and `mobile_voice_preset: bool`
  (default `true`).
* On Android, `AudioEngine::start` logs the preset + effects
  requests so a future cpal / Oboe upstream switch can be observed
  via the redacted diagnostic export.
* On iOS, the same log line documents the binding gap — Chanora
  iOS audio is documented-only for Beta per the release notes.
* On Linux desktop, the flags are honoured by name but the engine
  continues to use the default ALSA / PipeWire source. No
  behaviour change.

RISK-AUDIO-MOBILE-001 (new) tracks the actual preset switch. The
follow-up work either pulls in an Oboe-based input host or waits
for cpal upstream to expose `set_input_preset`. Either way the
config flag is forward-compatible — callers do not need to change
when the binding lands.

EdisonJwa 9790005c3e feat(beta): wire voice in/out end-to-end with push-to-talk (v0.2.0-beta.1)
Reaches the Internal Beta milestone of DEC-001's release sequence the
same day as Alpha. Adds voice capture and playback through the full
Flutter UI → FRB → Rust core → tsclientlib → server path.

Promotions from PoC:
  poc/audio-capture-playback-spike  →  crates/chanora_audio/

New product code:
  crates/chanora_audio/src/engine.rs — cpal capture and playback,
    audiopus Opus VoIP encoder (48 kHz mono 20 ms frames), tsclientlib
    AudioHandler for decode + jitter buffer + mix on playback,
    push-to-talk gate, graceful playback-only fallback when capture
    is unavailable.
  crates/chanora_protocol/src/adapter.rs — extended with
    voice_out_tx (clonable mpsc::Sender<OutPacket>) and
    take_voice_in() (one-shot mpsc::Receiver<InboundVoice>); main
    loop now interleaves outbound voice drain, event pumping, and
    control-request handling.
  crates/chanora_protocol/src/lib.rs — re-exports the few
    tsproto_packets types (OutAudio, OutPacket, InAudioBuf,
    AudioData, CodecType, Direction) that chanora_audio
    legitimately needs. Documented as the single deliberate
    cross-crate type re-export per SAD-067, justified by the
    performance cost of a parallel type hierarchy on the 20 ms
    voice frame.
  core/chanora_core/src/lib.rs — ChanoraSession::start_audio,
    set_ptt, audio_stats; disconnect now stops the engine first.
  crates/chanora_bridge/src/api.rs — startAudio, setPtt,
    audioStats commands and BridgeAudioStats DTO.
  apps/chanora_flutter/lib/main.dart — "Start audio" button +
    hold-to-talk PTT button with pressed/released visual state +
    live stats line (TX/RX/PTT). Stats polled every 500 ms.

ARB:
  Both en and zh-Hans gain startAudioAction, pttHoldToTalk,
  pttTransmitting, audioStatsLine. Banner updated to
  "Beta build — voice in/out wired; not production ready."

FRB config:
  flutter_rust_bridge.yaml gains local: true so codegen resolves
  the workspace member's library stem to "chanora_bridge" instead
  of falling back to "UNKNOWN".

Empirical verification (2026-05-14, against cn.teamspeak.app):
  cargo check + cargo test --workspace: all green.
  flutter analyze: 0 issues.
  flutter test: 4/4 passing including:
    - test/alpha_e2e_test.dart (regression: Alpha still works)
    - test/beta_e2e_test.dart (Beta: connect → startAudio →
      PTT cycle → disconnect against cn.teamspeak.app).
  Live smoke (cargo test alpha_smoke -- --ignored): 49 channels,
  37 clients retrieved.
  Capture stream open against the host PipeWire auto_null source
  refused (snd_pcm_hw_params); engine correctly logged the warning
  and continued in playback-only mode. TX=0 frames, RX=0 frames
  reflects the headless null-source environment; on a real mic
  host the encoder produces ~50 frames/second while PTT is held.

Honest Beta scope (NOT in this release):
  - AEC / AGC / NS / HPF DSP (DEC-007..010): AudioEffects exists
    as a struct but the filters are no-ops. Beta+ work.
  - Production-quality resampler: current code is linear
    interpolation. Beta+ work.
  - Identity persistence via chanora_storage: still ephemeral.
  - Push-to-Dart event stream: UI polls instead.
  - chanora_diagnostics tracing-layer wiring: still scaffold.
  - Mobile (Android) cdylib + UI: PoC-proven, not yet in product.
  - Reconnect / network-loss recovery for the voice path.

Docs updates:
  - docs/governance/product-decision-register.md bumped to v0.9.7
    (Beta-milestone change-history entry; no row changes).
  - docs/governance/poc-results-summary.md bumped to v0.6.0
    (RISK-PoC-005 updated with Beta progress).
