* feat(audio): add Silero ONNX VAD with WebRTC fallback
Introduce SileroOnnxVad and SileroOnnxVadWorker for desktop targets. The worker runs Silero v6 ONNX inference on a dedicated thread, accumulating 10 ms frames into the 512-sample 16 kHz input the model expects. Add VadOutput, VoiceActivityDetector trait, and WebRtcFallbackVad to provide a uniform VAD interface with graceful fallback when the ONNX model is unavailable. Wire the new VadBackend variants through AudioProcessingConfig and the snapshot stats so the bridge can report which detector is active.
* feat(audio): integrate desktop VAD worker into capture engine
Wire SileroOnnxVadWorker into the desktop capture path so voice activity can open the transmit gate before encoding. The capture callback now processes all audio through resample, downmix, and VAD unconditionally; transmit_active still gates Opus encoding.
Add new_desktop_audio_processing_state() to construct the config/stats/worker triple, and apply_desktop_vad_backend() to synchronously load or clear the worker on config changes. Override processing_backend to Noop for desktop so bridge diagnostics report the correct backend rather than the iOS-oriented PlatformVoiceProcessing default.
Includes review-driven cleanups: StreamConfig clone to deref per clippy, and a comment explaining why two try_lock calls on silero_vad_worker are structurally necessary (borrow checker requires the policy probe and the fallback path to not share a lock guard because mark_vad_fallback_active takes &mut self).
* fix(audio): modernize Windows PTT to current windows-rs API
Port the Raw Input plus low-level keyboard hook PTT backend to the newer windows-rs patterns: OptionalHandle, Result-returning CreateWindowExW, and None for CallNextHookEx. Replaces the old HHOOK(0) pointer casts. Add deterministic tests for mouse button 4 and 5 press and release driving the gate.
* build(windows): force MSVC release CRT for audiopus cmake builds
audiopus_sys calls cmake::build(opus_path), so downstream Cargo env cannot use cmake-rs Config::define() to override CMake's MSVC Debug CRT defaults. Point cmake-rs at a small wrapper that injects the policy and cache variables during configure while passing cmake --build, --version, and -E through unchanged. Keeps Opus Debug builds on Rust's release dynamic CRT (/MD) instead of CMake's default debug CRT (/MDd), which otherwise pulls in unresolved __imp__CrtDbgReportW symbols at test link.
Document that the iOS deployment target is intentionally absent from this file. It is enforced by tools/build-ios.sh and the Xcode project; setting it globally here would make native macOS cargo check runs try to link iPhone objects against the macOS SDK.
* build(flutter): update pubspec.lock after plugin additions
Regenerated lockfile reflecting the local_notifications and connectivity_plus plugin additions from the poke-notifications feature.
* fix(audio): address PR #37 review findings
Six fixes from independent PR review:
1. BLOCKER: Replace Windows-only cmake .cmd wrapper with cross-platform
CMake env vars. Setting CMAKE=tools/cmake-msvc-release-crt.cmd
globally broke non-Windows hosts because cmake-rs would try to
execute a .cmd file on macOS/Linux. Instead, set
CMAKE_POLICY_DEFAULT_CMP0091=NEW and CMAKE_MSVC_RUNTIME_LIBRARY=
MultiThreadedDLL as env vars that CMake reads natively. MSVC-
specific vars are safely ignored by GCC/Clang toolchains. Delete
the now-unnecessary wrapper script.
2. IMPORTANT: Join the Silero worker thread in Drop instead of
detaching it. The old code dropped the JoinHandle which detaches
the thread; the new code calls handle.join() after closing the
channel, ensuring the ONNX session is cleaned up before the
worker is replaced during config changes.
3. IMPORTANT: Single-try_lock refactor of the capture VAD callback.
The double try_lock (policy probe + send) is replaced by a single
scoped try_lock that both probes availability and sends the frame.
The guard is dropped before the fallback path, which needs &mut
self for mark_vad_fallback_active. This also eliminates the
VadWorkerPolicy enum and callback_vad_worker_policy function,
whose behavior is now inlined into the callback.
4. IMPORTANT: Remove tracing from the realtime capture callback.
mark_vad_fallback_active and sync_vad_backend emitted info!/warn!
from the audio thread. Replace with silent atomic state
publishing via SharedAudioProcessingStats; the bridge stats
stream already exposes vad_fallback_active for diagnostics.
5. IMPORTANT: Defer ONNX model load outside the worker mutex.
apply_desktop_vad_backend_to_worker now constructs the new worker
before taking the lock, then swaps it in under a short hold.
This prevents the realtime callback from being blocked during
model I/O + thread spawn.
6. MINOR: Remove unused VadBackend import from vad/mod.rs after
deleting the policy code.
* fix(audio): address PR #37 second-pass review findings
5-agent review found 5 blocking issues. All addressed:
1. BLOCKER: CMake env vars don't reach CMake cache. Restored .cmd wrapper
but scoped to Windows MSVC targets only via [target.x86_64-pc-windows-msvc]
and [target.aarch64-pc-windows-msvc] in .cargo/config.toml. Non-Windows
hosts are unaffected.
2. BLOCKER: processing_backend normalized in set_audio_processing_config
on desktop (cfg-gated override to Noop), mirroring startup default.
3. BLOCKER: Model-path reload was already wired via reload_audio_processing_config.
Fixed misleading doc comment in core/lib.rs.
4. BLOCKER: DEC-030 updated to reflect desktop VoiceActivity enablement.
Traceability docs (SRS, SysDes, SAD, SDD, implementation-status) updated.
5. Silero ONNX cfg narrowed to desktop-only (excludes macOS/Android).
Cargo.toml ort dependency target cfg narrowed similarly.
6. Realtime callback debt documented as TODO at CaptureState::ingest.
* fix(audio): exclude ort dep on Android target
ort does not provide first-class Android prebuilts in our pin, mirror the
iOS/macOS exclusion so cargo metadata succeeds for android targets.
* test(audio): fix stale select_ptt_backend import in ptt_privacy
The helper moved out of the ptt_backends submodule onto the crate root;
update the integration test imports so the test compiles again.
* build(windows): scope MSVC release CRT cmake wrapper via Cargo [env]
Cargo's [target.<triple>] table only forwards a fixed allowlist
(linker, runner, rustflags, rustdocflags, ar), so setting CMAKE there
was silently dropped and audiopus_sys kept linking the debug CRT,
producing LNK4098 'MSVCRTD conflicts' and __imp__CrtDbgReportW errors
on x86_64-pc-windows-msvc test builds.
Move the override to Cargo's [env] table using cc/cmake-rs's
target-suffixed CMAKE_<triple> lookup (force=true, relative=true) so it
applies to MSVC targets only and not to host tooling. Add stdout
markers to the wrapper so its invocation is provable in cargo -vv logs.
Verified: cargo test -p chanora_audio --target x86_64-pc-windows-msvc
--lib --no-run now links cleanly; CMakeCache.txt records
CMAKE_MSVC_RUNTIME_LIBRARY=MultiThreadedDLL and CMP0091=NEW.
* fix(flutter): gate VoiceActivity transmit mode by platform support
VoiceActivity relies on the native VAD worker, which is only wired up
on Windows, Linux, and Android. Showing the option on iOS, macOS, or
web let users select a mode that silently never transmitted.
Add voiceActivityTransmitAvailable + transmitModeSegmentsFor() helpers
in voice_settings_controls.dart, hide the VAD row in voice_compact.dart
and drop the VAD segment from the settings dialog when unsupported.
Keep the legacy const transmitModeSegments for the existing widget test
and add two new tests covering the gated helper.
* fix(ios-audio): add voice join session coordinator
* fix(ios-audio): activate session before voice joins
* docs(ios-audio): align activation lifecycle comments
* fix(ios-audio): keep session active when already-in-channel
The 'already in channel' server response (code 0x0302) is treated as a
successful join by _onJoinChannel: the user stays in the channel and
local state is updated to reflect the joined target. But the underlying
voiceJoin call still raises BridgeError_ServerRejected, which the
joinVoiceChannelWithIosAudioSession helper used to interpret as a join
failure and deactivate the iOS audio session. Result: the UI shows the
user as joined while the audio session is dead and capture/playback
remain silent.
Add an isJoinSuccess predicate to the ordering helper. When the
predicate matches, the helper rethrows (so the caller can still run its
success-on-already-joined branch) without deactivating the session.
Wire _onJoinChannel to pass _isAlreadyInChannel as the predicate so the
0x0302 path keeps the session active.
Adds two regression tests covering the success-on-rethrow and the
predicate-false-still-deactivates paths.
* docs(security): regenerate license inventories
Cargo inventory: pick up chanora_resolver bump from 0.1.0 to
0.2.0-beta.1 so it matches the workspace; also adds a trailing newline
so 'cargo about generate' is idempotent in CI license-drift checks.
Flutter inventory: pick up flutter_local_notifications (+ platform
interfaces) and timezone pulled in by the prior notification
permission work.
Adopt a call-scoped VoIP audio session lifecycle so other apps' audio is
not stopped while Chanora is idle and the in-call session does not get
clobbered by media-server resets unrelated to voice.
AppDelegate.swift
- Set .ambient + .mixWithOthers as the idle baseline so the app does not
hold a VoiceChat session when no call is active.
- Switch to .playAndRecord + .voiceChat + .mixWithOthers + .duckOthers
on demand via the new chanora/ios_audio_session MethodChannel, and
revert to .ambient on deactivate.
- Gate the media-services-reset rebuild on voiceSessionActive so a
stray reset during idle no longer reactivates VoiceChat.
ios_audio_session_controller.dart (new)
- Thin Dart wrapper around chanora/ios_audio_session with activate/
deactivate; no-op on non-iOS; swallows PlatformException to keep
audio start/stop resilient to platform-side races.
main.dart
- Activate the iOS audio session on BridgeEvent_AudioStarted, deactivate
on BridgeEvent_AudioStopped, fire-and-forget via unawaited().
ios_voice_unit.rs
- Add the 10 local bindings required by the render-callback closure
preamble (wav_recorder_for_render, render_recorder_active,
render_ref_len, render_ref_accum, cb_count, last_num_frames,
num_frames_changes, callbacks_with_audio, callbacks_with_silence)
so the iOS target compiles cleanly with the new lifecycle wiring.
Tests
- 5 unit tests in test/services/ios_audio_session_controller_test.dart
cover activate/deactivate on iOS, no-op on non-iOS, and graceful
PlatformException handling.
Docs
- SRS SRS-110 expanded to cover the call-scoped lifecycle invariant.
- SysDes mobile-voice row updated to reflect the MethodChannel and
.ambient idle baseline.
- implementation-status-2026-05-28 voiceChat row flipped to done.
Verification
- flutter analyze: No issues found (2.8s)
- flutter test: 195 passed / 2 skipped / 0 failed
- cargo build -p chanora_audio --target aarch64-apple-ios: clean
- cargo build -p chanora_audio (macOS host): clean
Device QA matrix (Spotify-keeps-playing-while-idle, mix-during-call,
revert-on-call-end, media-services-reset-during-idle) remains pending
on physical hardware.
- _showLocalNetworkDeniedSnackBar: wrap Process.run with unawaited()
and .catchError() so a rejected future (e.g. macOS sandbox refuses
fork, or 'open' is missing) cannot bubble into the Flutter zone
as an unhandled exception. The synchronous try/catch was a no-op
because Process.run only throws asynchronously.
- macos_permissions_service_test.dart: mirror the
triggerLocalNetworkPrompt error-handling test with one for
checkLocalNetworkAccess. Probe-path failures (NWConnection probe
cannot establish, or Swift side throws) must fall back to cached
state without crashing the caller.
Tests: 186 passed, 2 skipped. Dart analyze clean.
Oracle re-review on PR #30 flagged that _ChatDetailViewState only
called onDraftChanged when _textCtl.text was non-empty. The empty
case is load-bearing: if the user restored a saved draft, deleted
the text, then switched target (or closed the panel), the parent's
draft map kept the stale entry and resurrected it on the next swap.
Fix: call onDraftChanged unconditionally in both didUpdateWidget
(target change) and dispose (tear-down), so the parent map learns
when a draft is now empty.
Adds a regression test exercising the restore-clear-swap sequence.
- ViewportInfo.updateShouldNotify: compare layoutClass only
(not width/height), avoiding unnecessary rebuilds on every
resize frame within the same layout class.
- ChatPanel: use BorderDirectional(start:) for RTL support.
- ChatPanel: localize 'Close chat' tooltip via AppL10n.chatCloseAction.
- Inline panel snackbar: localize via AppL10n.chatPanelCollapsedHint.
New en/zh ARB entries added.
- _saveCurrentDraft(): removed — it was a self-assignment no-op.
Draft persistence relies on ChatDetailView's didUpdateWidget
(fires onDraftChanged on target switch) and dispose (fires on
panel tear-down), both of which already populate _chatDrafts
correctly without an explicit save call.
- _handleInlineChatViewport layout snackbar: use AppL10n.
- Audio level-meter: switch from callback-count (% 3) to time-based
gating (std::time::Duration::from_millis(33)), robust to cpal
buffer-size or sample-rate changes. Remove level_decimation_counter.
- chat_panel_test.dart: add AppL10n.localizationsDelegates so the
test resolves l10n keys.
Tests: 183 passed, 2 skipped. Dart analyze clean.
cargo test -p chanora_audio --lib: 125 passed.
apps/chanora_flutter/macos/Runner/MacOSAudioLifecycle.swift (new): native MethodChannel handler for chanora/macos_audio_lifecycle. Observes Core Audio HAL default-input and default-output device property changes via AudioObjectAddPropertyListener; posts handleDefaultDeviceChange events with {role: input|output} payload. Mirrors the iOS chanora/ios_audio_lifecycle event surface minus the AVAudioSession-specific events (no interruption / no media services reset equivalents on macOS — no AVAudioSession).
apps/chanora_flutter/macos/Runner/MainFlutterWindow.swift: register MacOSAudioLifecycle next to MacOSPermissionsHandler in awakeFromNib. Closes the iOS/macOS asymmetry noted in SysRS-051.
apps/chanora_flutter/lib/services/audio_lifecycle_service.dart: add wireMacosAudioLifecycle() parallel to wireIosAudioLifecycle() / wireAndroidAudioLifecycle(). The current implementation captures and logs the events; the FRB function that triggers a VPIO re-bind on the engine is a follow-up. Event-shape mirrors the iOS side so a future caller can switch on platform without changing the dispatch shape.
apps/chanora_flutter/test/services/audio_lifecycle_service_test.dart: smoke test for wireMacosAudioLifecycle (4 tests pass, including the new one).
- Replace broad POSIX error checks (EACCES/EPERM/ENETDOWN) with the
canonical kDNSServiceErr_PolicyDenied DNS error in the NWBrowser
state handler, matching the pattern used by Expo, Pulse, Strongbox,
and WLED. Detect denial in both .failed and .waiting states.
- Add checkLocalNetworkAccess(host:port:) — a read-only NWConnection
probe (Sequel-Ace pattern) that checks
NWPath.unsatisfiedReason == .localNetworkDenied without triggering
a new system prompt. Useful for confirming denial against a specific
destination before attempting to connect.
- In _onConnect, after the prompt resolves to Denied, confirm with
checkLocalNetworkAccess against the target host. If confirmed,
abort the connect attempt and show a non-modal snackbar with an
'Open System Settings' action that deep-links to
Privacy_LocalNetwork. Previously the app would proceed to connect,
fail with PermissionDenied, and surface a redundant in-app modal.
- Drop the now-orphaned _openIosAppSettings helper and
_iosPlatformChannel constant (the only caller was the removed
in-app permission dialog).
- Add unit tests for checkLocalNetworkAccess covering outbound
MethodCall arguments and state parsing for Granted/Denied.
Trace: SRS-300.
apps/chanora_flutter/lib/services/audio_lifecycle_service.dart: extend parseBridgeAudioRoute to handle 'UsbHeadset' (maps to wiredHeadset — USB audio is functionally a wired-class device, matching AndroidAudioLifecycleController.classifyCurrentRoute's own preference ordering at line 176) and 'Hdmi' (maps to unknown — HDMI is a display-out transport, not a voice-call audio path; no existing BridgeAudioRoute variant fits; safer to leave as unknown than to misclassify as Speaker). Previously these Android-emitted strings hit the default branch and silently became BridgeAudioRoute.unknown.
apps/chanora_flutter/test/services/audio_lifecycle_service_test.dart: split the existing single test into three — iOS-classified strings (preserved), Android UsbHeadset (new), Android Hdmi (new). flutter test: 3 passed, 0 failed.
* feat(voice): add real-time mic input level metering at 30 Hz
Expose input RMS from the audio engine through the bridge as a
dedicated Rust→Dart Stream<double>, replacing the binary on/off
indicator with a proportional dBFS level meter.
Rust side:
- chanora_audio: add set_input_dbfs/input_dbfs accessors to
SharedAudioProcessingStats; restructure CaptureState::ingest()
to compute dBFS from mono buffer before the PTT guard so the
meter shows mic activity even when not transmitting.
- chanora_core: widen audio_stats() return to include f32 input
level.
- chanora_bridge: add input_level: f32 to BridgeAudioStats and
new input_level_stream(sink: StreamSink<f32>) that pushes at
~30 Hz via tokio interval task.
- Update frb_generated.rs serialization for the new field.
Flutter side:
- VoiceLevelMeter: accept optional double level (dBFS), map
-60..0 dBFS to 0..1 fill fraction, animate with
TweenAnimationBuilder for smooth transitions.
- voice_compact.dart: subscribe to inputLevelStream in the voice
details sheet for 30 Hz meter updates, keeping 250 ms poll for
TX/RX counters.
- voice_bar.dart: accept optional inputLevel from the stream.
- main.dart: subscribe to inputLevelStream, pass to VoiceBar.
* chore: sync Flutter build config and dependency updates
- Add Flutter migrator flags to gradle.properties (builtInKotlin, newDsl)
- Add FlutterGeneratedPluginSwiftPackage to iOS/macOS Xcode projects
- Update meta 1.17→1.18, test_api 0.7.10→0.7.11
- Rebuild chanora_bridge framework for macOS
- Update Podfile.lock for iOS and macOS
* fix(voice): correct meter animation, pre-gain dBFS, stream lifecycle, and protocol warnings
B1: Convert VoiceLevelMeter to StatefulWidget tracking previous fill
as Tween begin so the meter animates smoothly instead of resetting
to zero on every frame.
B2: Compute dBFS from pre-gain mono samples in CaptureState::ingest()
so the level meter reflects raw mic input, matching mobile paths.
B4: End input_level_stream after 10 consecutive session errors instead
of emitting -120 dBFS forever when the session is gone.
Also fixes all 13 clippy warnings in chanora_protocol: collapsed
nested if-let patterns, replaced .ok() + Some matching with Ok, used
? operator, and introduced EventChannels struct to reduce the four
helper functions below the 7-argument threshold.
* fix(voice): use MissedTickBehavior::Skip for level meter stream and align dBFS doc
Set MissedTickBehavior::Skip on the input_level_stream tokio interval
so slow audio_stats() calls skip missed ticks instead of bursting,
preventing CPU spikes on the UI meter thread.
Align VoiceLevelMeter class doc: the mapping floors at -60 dBFS
(via dbfsToFraction), not the full -120 range.
* feat(macos): add macOS permissions service for Input Monitoring, Local Network, and Notifications
Add MacOSPermissionsService (Dart) + native MethodChannel handler (Swift)
for macOS-specific permissions not covered by permission_handler:
- Input Monitoring (CGPreflightListenEventAccess /
CGRequestListenEventAccess) for global PTT via Event Tap
- Local Network Privacy prompt (NWBrowser for _ts3._tcp, macOS 15+)
- Notifications (UNUserNotificationCenter authorization)
Trace: SRS-198, SRS-297, SRS-300, SysRS-166, SDD-091
Changes:
- Info.plist: add NSBonjourServices array with _ts3._tcp
- macos_permissions_service.dart: Dart service with MethodChannel,
ValueNotifier states, PTT capability derivation (L0Focused /
L1MacOSEventTap), non-macOS short-circuit
- MainFlutterWindow.swift: native handler registered as FlutterPlugin,
Input Monitoring check/request/polling, NWBrowser trigger with
denial detection, UNUserNotificationCenter request
- main.dart: wire service into bootstrap lifecycle, listen for PTT
capability changes from Input Monitoring state
- macos_permissions_service_test.dart: 17 unit tests covering inbound
state changes, outbound calls, lifecycle, error handling, platform
behavior (179/179 full suite pass)
* fix(macos): keep permissions capability state live
* fix(ui): restore speaking status indicators
Speaking state (isSpeaking) is computed from voice activity timestamps
in the protocol layer and cannot be represented as a discrete delta.
The event-driven refactor removed periodic snapshot refreshes, causing
speaking indicators to go stale.
Adds a 750ms periodic snapshot refresh (matching SPEAKING_ACTIVITY_WINDOW)
while the audio stats timer is active (in-channel only). Structural
changes (moves, joins, leaves) are still handled by instant deltas.
* fix(ui): hide server query clients from delta joins
When a ServerQuery client sends a message, a ClientJoined delta fires.
Before PR#15 the periodic snapshot rebuild would include the SQ client
but the snapshot_view filter hid it. With deltas, the client persisted
in the local snapshot. Now ClientJoined deltas skip SQ clients entirely.
* fix(proto): log getconnectioninfo errors instead of silently discarding
Ping and packet loss showing 'Unknown' in the client info sheet is
caused by getconnectioninfo failures being silently swallowed. Now
logs the error with the client_id so the root cause can be diagnosed
(e.g. missing b_client_connectioninfo_view permission on the server).
Also logs clientgetvariables failures.
* fix(proto): refresh non-self client profiles before mapping
* feat(protocol): add ping deviation to client profiles
* chore(ui): regenerate Flutter bridge bindings for ping deviation
* fix(l10n): add ping deviation labels to client info
* feat(ui): show ping deviation in client info sheet
Clarify ONNX Runtime guidance with direct-open install hints, restore desktop WebRTC VAD visibility, map mouse side buttons through focused PTT capture/runtime paths, and wait for server acks before showing chat sends as successful.
Constraint: Linux release UX must stay functional when ONNX Runtime is optional and GNOME portal availability varies
Rejected: Keep desktop VAD locked to Silero only | misleads users when ONNX Runtime is skipped
Confidence: medium
Scope-risk: moderate
Directive: Preserve the protocol send-ack wait path for chat so UI success always tracks real server acceptance
Tested: flutter analyze lib/main.dart lib/widgets/chat_views.dart lib/widgets/input_dialogs.dart lib/widgets/startup_dependency_screen.dart; flutter test test/widgets/input_dialogs_test.dart test/widgets/chat_views_test.dart test/services/startup_dependency_check_test.dart test/widgets/startup_dependency_screen_test.dart test/widgets/voice_settings_controls_test.dart test/widgets/audio_processing_config_state_test.dart; cargo test -p chanora_protocol --lib; cargo test -p chanora_audio ptt_backends --lib
Not-tested: Live manual GNOME portal rebind/global PTT on a real desktop session; observer-bot chat against a live server after the sender-name fallback change
Previously the PttController handed its real AudioTransmitGate to
the platform backend and the backend wrote transmit_active directly
on every key edge — bypassing the 200 ms release tail and the
TransmitMode selector entirely. The tail timer was constructed and
exposed on ChanoraSession but never received any input, so SDD-096
and SRS-206 were spec-only.
Wire it: PttController now owns a synthetic 'press-edge gate' which
it hands to the backend in place of the real one. An internal
edge-watcher task subscribes to that press-gate, translating
true/false transitions into ReleaseTailTimer.key_down/key_up calls.
The release-tail timer feeds the selector's ptt_held input; the
selector recomputes transmit_active honouring mode, in_channel,
and hard_mute, and writes the real gate. Single owner of
transmit_active is preserved (SAD-083 invariant).
PttController::new now takes Arc<ReleaseTailTimer> instead of
AudioTransmitGate; ChanoraSession threads its session-scoped timer
through both the start_audio path and the supervisor reconnect
path. The legacy bridge set_ptt call (still used by the in-focus
Listener fallback and the e2e test) is rerouted through the timer
so the same tail and mute semantics apply uniformly.
ReleaseTailTimer gains force_release() — cancels any pending task
AND clears the selector's ptt_held. PttController::stop uses it so
shutdown can't leave transmit_active stuck at true.
Tests
- press_edge_drives_selector_through_release_tail: backend press
edge → real gate follows, key_up → tail keeps gate true for tail
window then clears.
- stop_clears_press_and_cancels_tail: stop() drops transmit even
with a tail in flight.
- e2e test now sets release_tail_ms=0 + waits one tick so the
pttActive=false assertion isn't racing the default 200 ms tail.
cargo test --workspace --lib: 74 passed / 0 failed / 1 ignored
(+2 new tests vs. the previous 72).
flutter analyze: clean (6 pre-existing Radio.groupValue infos).
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).
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.
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).
First Internal Alpha build per DEC-001. Closes the milestone of
'Flutter UI calls Rust via the typed bridge, Rust connects to a
TeamSpeak-compatible server through tsclientlib, returns a typed
snapshot, and disconnects cleanly.' Audio remains Beta scope.
Promotions from PoC:
poc/tsclientlib-connect-spike → crates/chanora_protocol/
New product code:
crates/chanora_protocol/src/{dto.rs,adapter.rs} — typed boundary
over tsclientlib. Tokio task owns the Connection; public
handle communicates via mpsc/oneshot. No tsclientlib types
cross out of the crate (SAD-067 / SysDes-011 / SysDes-029).
core/chanora_core/src/lib.rs — ChanoraSession composes the
protocol crate, enforces the DEC-006 single-connection
invariant.
crates/chanora_bridge/src/{api.rs,frb_generated.rs} — FRB 2.12.0
bridge per DEC-014. cdylib + staticlib + rlib. Typed
BridgeSnapshot / BridgeChannel / BridgeClient / BridgeError
DTOs. Process-wide OnceLock<Runtime> + OnceLock<ChanoraSession>.
flutter_rust_bridge.yaml at repo root.
apps/chanora_flutter/lib/main.dart — Alpha UI: server form,
connect button, channel tree, disconnect.
apps/chanora_flutter/lib/l10n/app_{en,zh}.arb expanded with the
Alpha key set; ARB metadata reaffirms ADR-008 for
server-provided content.
Generated Dart bindings under apps/chanora_flutter/lib/src/rust/.
Empirical verification (2026-05-14):
Workspace: cargo check + cargo test clean
(workspace tests: all green).
Bridge cdylib: target/release/libchanora_bridge.so produced
(~15 MB).
Flutter: flutter analyze clean; flutter test runs 3/3 green
including the alpha_e2e_test that drives the full
Dart → FRB → chanora_bridge → chanora_core → chanora_protocol
→ tsclientlib → UDP → cn.teamspeak.app
path. The captured logcat/stdout shows the tsproto resender
transitioning Connected → Disconnecting → Disconnected on
clean teardown.
Architecture changes:
- Removed the chanora_core ↔ chanora_bridge cyclic dependency.
chanora_core no longer knows the bridge exists; the bridge
maps from CoreError.
- chanora_bridge crate's #![forbid(unsafe_code)] lint relaxed
because FRB-generated glue legitimately uses unsafe at the
FFI boundary. Hand-written code remains unsafe-free.
Open follow-ups (NOT in this Alpha):
- Audio capture/playback wiring into chanora_audio
(Beta scope per DEC-001).
- Identity persistence via chanora_storage
(currently regenerated on every connect).
- Per-message diagnostics + redaction
(chanora_diagnostics still scaffold).
- Reconnect / network-loss recovery.
- Mobile (Android) build of the bridge cdylib + UI verification.
Implements the canonical implementation directory layout adopted by
DEC-022 (register v0.9.5). Closes the scaffolding phase; no PoC code
has been promoted in yet (per proof-of-concept-plan.md §4 a PoC is
not product code unless explicitly promoted).
Rust workspace
==============
Top-level Cargo.toml declares seven workspace members:
core/chanora_core top-level Rust API + orchestration
crates/chanora_protocol tsclientlib isolation (SAD-067, SysDes-011/029)
crates/chanora_state state sync, reducers, deltas
crates/chanora_audio capture, DSP, Opus, jitter, mixer, playback
crates/chanora_storage non-secret DB + platform secure store
crates/chanora_diagnostics logs, redaction, export
crates/chanora_bridge typed Flutter/Rust DTOs
Workspace-wide pins:
license = "MIT OR Apache-2.0" (DEC-020)
rust-version = "1.95"
edition = "2021"
The Flutter app (apps/chanora_flutter) is NOT a Cargo workspace
member; it is owned by the Flutter / Gradle toolchain and is in the
workspace exclude array along with every poc/* spike.
Each crate ships:
* a Cargo.toml referring to workspace.dependencies pins;
* a lib.rs with #![forbid(unsafe_code)] + #![warn(missing_docs)],
a typed Error enum, and the public types relevant to the
subsystem's role per SAD §7.2;
* minimal unit tests so

chanora_core's CoreError type-wraps every subsystem error via
#[from] so callers can match on origin without parsing strings.
chanora_audio's AudioEffects struct defaults all four effects to
true, matching DEC-007 (AEC), DEC-008 (AGC), DEC-009 (NS),
DEC-010 (HPF). A unit test pins this so a future regression that
flips a default fails immediately.
chanora_diagnostics exports REDACTION_MARKER = "[REDACTED]",
identical to the PoC's marker so audit grep patterns survive the
promotion.
chanora_bridge's BridgeError is Serialize + Deserialize so it can
flow across the FRB 2.x boundary (DEC-014).
Empirical verification: cargo check --workspace clean, cargo test
--workspace clean (7 unit tests + 7 doc-test runners, all passing)
against Rust 1.95.0 stable.
Flutter app
===========
apps/chanora_flutter created with .
DEC-004 applied: minSdk overridden to 28 in
android/app/build.gradle.kts with a comment that points back at the
decision register and forbids lowering it without re-opening DEC-004.
DEC-015 applied: shipped English + Simplified Chinese at MVP.
- pubspec.yaml gains flutter_localizations + intl + generate:true.
- l10n.yaml emits lib/l10n/generated/AppL10n (no synthetic package
— that was removed in Flutter 3.41+).
- lib/l10n/app_en.arb is the source of truth; lib/l10n/app_zh.arb
mirrors the key set in zh-Hans. ARB metadata explicitly
reaffirms ADR-008: server-provided content (channel names,
nicknames, welcome banners) is preserved verbatim and never
translated.
lib/main.dart and test/widget_test.dart were rewritten from the
template counter into a minimal localized scaffold that proves
both locales render correctly.
Empirical verification: reports no issues;
runs the two locale smoke tests and both pass.
