Delete ios_raw_unit.rs (538 lines) and all SonoraExperimental references
from the core audio crate. The experimental RemoteIO path that bypassed
Apple VPIO in favor of software WebRTC APM was never shipped and is no
longer needed. VPIO is the sole production iOS audio backend.
- Delete ios_raw_unit.rs entirely
- Remove Raw variant from IosVoiceBackend enum in engine.rs
- Remove SonoraExperimental from IosVoiceProcessingMode enum
- Simplify validate_for_ios() (single-variant enum, no mode check)
- Remove 2 SonoraExperimental validation tests
- Remove ios_raw_unit module declaration from lib.rs
- Remove include_str!-based debug_wav test for the deleted file
* 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.
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.

The macOS start path spawns a tokio producer task that holds clones

gain/muted atomics, then loops on a 20 ms tokio interval. Without
a shutdown signal the task runs forever on engine stop/restart and
leaks all four Arcs every cycle. Drop now stores 'true' on the
flag; the producer checks it at the top of each tick and exits,
releasing its clones within at most one 20 ms tick.
- macos/Runner/Release.entitlements: strengthen the existing

Document the specific failure mode (tokio::net::UdpSocket::bind

The PR #27 refactor moved the iOS render callback to a direct-fill
path with its own peak_i16 == 0 check, dropping the !muted gate
that PR #28 added to the pre-refactor callback. Without this
gate, every muted callback fires a false-positive
increment_output_underrun() because the downmix helper writes
silence (peak_i16 = 0) by design when muted.
Re-apply PR #28's gate to the refactored iOS path so this PR does
not silently reintroduce the bug PR #28 was opened to fix.

crates/chanora_audio/src/engine.rs: drop the macOS-specific event-queue producer/consumer path; macOS now uses the iOS-style direct AudioHandler::fill_buffer in the VPIO render callback. The shared AudioHandler is an Arc<Mutex<...>>; the realtime callback uses try_lock so it never blocks on the tokio decode task (see ios_voice_unit.rs render callback).
crates/chanora_audio/src/mobile_voice_backend.rs: update VoiceAudioParams cfg gates — handler is now the iOS/macOS/desktop shape (Arc<Mutex<AudioHandler<SessionAudioId>>>), event_producer is Android-only.
crates/chanora_audio/src/lib.rs: widen the audio_event_queue module visibility to test so the macOS-specific path can be exercised by the unit test suite.
Cargo.toml: bump cpal 0.17.3 -> 0.18.0, jni 0.21 -> 0.22.4, windows 0.54 -> 0.62, criterion 0.5 -> 0.8. Cargo.lock follows.
voice_render.rs: new limit_peak_inplace helper (single-pass, allocation-free peak scaler) with 4 unit tests. Applied in both the macOS and iOS render callbacks before the i16 conversion to prevent hard clipping on multi-client mixes that sum past 0 dBFS. Threshold 0.99 keeps the limiter transparent for normal voice levels (sub-millisecond per-frame latency at 48 kHz; pumping risk negligible for speech).
ios_voice_unit.rs: limit_peak_inplace call sites added to the macOS producer/ring render callback (per-frame, 2-element stack array) and the iOS direct-fill_buffer render callback (per-callback, on the scratch_stereo buffer); the downmix helper's hard-clamp is kept as defense-in-depth and is not expected to engage in the integrated flow.
- ios_voice_unit.rs:856-868: Revert iOS render callback from blocking
lock() back to try_lock() with silence-on-contention (WouldBlock
branch increments callback_xrun stat and returns the pre-zeroed
scratch buffer). Blocking lock() inside the CoreAudio HAL render
callback can stall the realtime IO thread when the decode task on
engine.rs:1309 holds the same AudioHandler Mutex, re-introducing
the underrun pattern this codebase already fixed elsewhere.
- ios_voice_unit.rs:782: Preallocate scratch_stereo to Apple's VPIO
MaximumFramesPerSlice (4096 frames * 2 channels = 8192 f32) at
setup time, so the realtime render callback never grows the Vec
via resize(). The defensive 'len() < needed' branch is kept for
the (impossible) case that the audio unit later raises max frames.
- main.dart:52-56: Gate _showAudioDebugOverlay behind kDebugMode &&
_isMacOS so the internal audio stats panel does not ship in
release builds. kDebugMode is a Dart compile-time const, so the
overlay subtree is tree-shaken out of release/profile binaries.
- Rebuilt macOS chanora_bridge.framework binary (universal arm64 +
x86_64) from the fixed source with the new CARGO_PROFILE_RELEASE_*
env vars (DWARF preserved for dsymutil). install_name patched back
to @rpath/chanora_bridge.framework/Versions/A/chanora_bridge.

macOS realtime audio was suffering buffer underruns on CoreAudio's VPIO
output callback. Root cause was twofold: AudioHandler was decoded under
a Mutex held across the realtime callback, and the render path
hard-coded mono i16 output regardless of the channel count the
callback actually exposed (CoreAudio occasionally hands the callback
stereo or quad output buffers, in which case writing only every Nth
sample produced silence + clicks).
This change brings macOS in line with the lock-free Android audio
architecture introduced for output stutter elimination:
* chanora_audio: AudioPacket / AudioCommand / AudioEventQueue
(previously gated to `target_os = "android"`) are now compiled on
macOS too. The decode loop in AudioEngine pushes inbound packets
into the queue; the VPIO render callback owns AudioHandler outright
and drains the queue, so the realtime thread never blocks on a
cross-thread mutex. set_client_volume also routes through the
command queue on macOS instead of locking the handler.
* voice_render.rs: new downmix_stereo_f32_to_interleaved_i16 helper
downmixes stereo f32 from AudioHandler to mono i16 and replicates
that mono sample across every output channel the callback exposes.
The existing downmix_stereo_f32_to_mono_i16 helper is retained for
iOS, where VPIO is reliably configured for single-channel output
via the AudioUnit stream format we pin at unit-create time.
Compile-gated to ios + test so the macos build doesn't warn on
dead code.
* ios_voice_unit.rs: render callback reads data.channels from the
args struct and forwards it to the new interleaved helper, so the
macOS path tolerates whatever channel count CoreAudio assigns. A
level decimation counter avoids running sqrt+log10 on every
callback (~93 Hz) when the Flutter consumer only reads at 30 Hz;
same regression class as the capture-side fix already in engine.rs.
* mobile_voice_backend.rs: VoiceAudioParams now carries
event_producer on macOS, and the AudioHandler is no longer wrapped
in Arc<Mutex<…>> on macOS because ownership moves into the render
callback. iOS keeps Arc<Mutex<…>> because its callback design
shares the handler with the decode task.
* lib.rs: audio_event_queue module is now compiled on macOS in
addition to android.
apps/chanora_flutter/lib/main.dart wraps the home tree in a Stack and
overlays AudioDebugStatsPanel on macOS so the live engine counters
(callback rate, drift, queue depth) used to diagnose the underrun are
visible while iterating on this code. iOS and other platforms are
unaffected.
apps/chanora_flutter/macos/Frameworks/chanora_bridge.framework binary
is rebuilt with these changes so flutter run on macOS picks up the new
realtime path without requiring developers to rebuild the Rust crate
locally. cargo check -p chanora_audio passes on macOS host.
ios_voice_unit.rs:1033: change the condition from `mix_stats.peak_i16 == 0` to `mix_stats.peak_i16 == 0 && !muted`. When the user mutes the channel via output_muted, the downmix helper fills the output buffer with silence (peak = 0), which previously falsely incremented the output_underrun counter. The mute toggle is intentional silence, not a real underrun.
Note: this does not address the separate false positive where peak_i16 == 0 with output unmuted but no audio incoming (e.g., just joined a channel with no remote speaking). A complete fix would require tracking whether the audio handler actually produced data; deferred to a follow-up.
* feat(voice): unified mobile voice bar with gesture-isolated PTT row
Replace separate VoiceStatusChip + VoicePttButton with a single
CompactVoiceBar widget that combines both into a two-row layout:
- Control row (tap): status text, mute, deafen, settings chevron
- PTT row (hold): full-width hold-to-talk, shown only in PTT mode
Gesture isolation prevents mis-touch between rows: the control row
uses tap-only InkWell/IconButton while the PTT row uses a raw
Listener for pointer-down/up events.
Key changes:
- Add CompactVoiceBar widget with state-colored container (normal,
muted, talk-power-blocked)
- Remove mute/deafen IconButtons from AppBar headerActions
- Restructure voice details sheet into primary section + collapsible
ExpansionTiles (audio processing, PTT capability, debug)
- Optimistic state updates for mute/deafen to eliminate tap delay
- Instant PTT visual feedback (no AnimatedContainer fade)
- Constant geometry across all states (no layout shift on toggle)
* fix(voice): preserve current PTT button format
* feat(voice): move mute/deafen controls into VoiceStatusChip
* fix(voice): ensure consistent chip height across mute states
Remove isSelected/selectedIcon from IconButtons inside VoiceStatusChip.
Material 3 toggle IconButtons (_SelectableIconButton) can vary in height
when the selected state changes due to tap target sizing. Use simple
conditional icons instead and set shrinkWrap tap target size with tight
constraints for stable 40x40 buttons regardless of state.
* fix(voice): remove leftover duplicate mute/deafen buttons in VoiceStatusChip
* fix(voice): replace unsafe stereo cast with bytemuck and localise talk-power tooltip
Replace the raw-pointer `&mut [(f32, f32)]` to `&mut [f32]` cast in
the oboe output callback with `bytemuck::cast_slice_mut`, eliminating
the unsafe block and relying on bytemuck compile-time NoUninit
verification instead.
Add voiceTalkPowerBlocked l10n key (en + zh) and replace the only
remaining hard-coded English tooltip in VoiceStatusChip with it.
* 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.
* fix(audio): eliminate Android output stutter via Oboe config + lock-free callback
Phase 1 — Oboe configuration:
- Change output stream from Usage::VoiceCommunication to Usage::Game with
ContentType::Sonification to avoid forcing the Legacy (OpenSL ES) data
path on most devices (Oboe issue #2075)
- Switch output format from i16 Mono to f32 Stereo, matching Qint's proven
configuration and eliminating per-callback downmix conversion
- Set buffer size to 2x burst after stream open, reducing default buffer
from 8-20x burst to 2x burst for lower latency
- Remove scratch Mutex<Vec<f32>>; callback writes directly to Oboe buffer
Phase 2 — Lock-free output callback:
- Add audio_event_queue.rs: lock-free SPSC bridge using crossbeam ArrayQueue
with separate packet (lossy) and control (reliable) channels
- OutputCallback now owns AudioHandler directly (no Arc<Mutex<>> on Android)
- Inbound forwarder pushes packets via AudioEventProducer (no mutex)
- set_client_volume pushes control commands via event queue on Android
- iOS/desktop Arc<Mutex<AudioHandler>> path unchanged
* fix(audio): address PR #20 review findings
- Store AudioEventConsumer directly in OutputCallback to eliminate
per-callback Arc clone on the real-time audio thread
- Add SAFETY comment for the unsafe from_raw_parts_mut transmute
- Bound set_client_volume spin-loop to 64 retries with warn log
- Remove redundant crossbeam-utils direct dependency
- Regenerate license inventory for new crossbeam deps (CI fix)
* fix(audio): use ASCII TODO punctuation
* docs(rust): add doc comments to delta enums and fix dead_code warnings
Add missing documentation to ProtocolDelta, CoreDelta, and BridgeDelta
enum variants and their struct fields across the protocol, core, and
bridge crates. Document the ChannelId::ROOT constant and the
take_delta_rx adapter method.
Fix dead_code warnings:
- keyring_disabled: add #[cfg] gate matching its callers
- snapshot_signature: add #[cfg(test)] for future test use
* fix(rust): correct `order` field docs to predecessor channel ID, narrow audio engine cfg gates
- Correct `order` field documentation in ProtocolDelta, SessionEvent,
and BridgeEvent from 'sort order' to 'predecessor channel ID
(TeamSpeak linked-list ordering hint)' per Copilot review feedback.
- Narrow AudioEngine voice_out_tx, voice_activity_selector, and mic_gain
cfg gates from ios+macos+android to android-only, since these fields
are only read from self in android_restart_voice_unit. On iOS/macOS the
values are passed directly to the voice backend at construction time.
* 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
* chore: regenerate Cargo.lock after rebase
* fix(ui): add 1s cool-down to prevent double-tap channel join
voiceJoin returns instantly (fire-and-forget protocol), so the
pending-join guard clears before a second tap lands. The cool-down
prevents the rapid channel oscillation and ClientIsFlooding (524)
that results from double-tapping.
* fix(ui): handle ChannelAlreadyIn as success, ClientIsFlooding with backoff
- ChannelAlreadyIn (0x0302): treat as silent success, update UI state
- ClientIsFlooding (0x020c): show localized snackbar, extend cooldown 5s
- Add l10n strings for flooding error (en + zh)
* fix(proto): use Windows TS3 client version for broadest compatibility
Matches Qint's default (Windows_3_X_X__1). Avoids server-side
behavioral differences with TS5 version strings.
* fix(proto): patch tsproto-types to handle short P-256 coordinates
BigInt::to_bytes_be() strips leading zeros, causing WrongPublicKeyLength
when a server's ephemeral key coordinate starts with 0x00. Patch from
EdisonJwa/tsclientlib fix/p256-short-coordinate-pad branch left-pads
coordinates to the P-256 field size instead of rejecting them.
* refactor(core): stop watchdog from emitting SnapshotChanged
The watchdog now serves only as a liveness probe (miss counting for
reconnection). UI updates are handled entirely by the event-driven
delta path (ProtocolDelta → SessionEvent → BridgeEvent → Flutter).
Removes signature tracking and SnapshotChanged emission from the
supervisor loop. The initial snapshot is still fetched via the
Connected event handler in Flutter.
* refactor(ui): remove channel-join cooldown guard
With event-driven deltas the UI updates instantly on channel moves,
so the 1-second cooldown is no longer needed. Double-taps are handled
by the server (ChannelAlreadyIn → success) and the pending-channel-id
guard prevents overlapping requests.
Also removes the _lastJoinCompletedAt field entirely.
* fix(core): reattach event forwarders after reconnect
The reconnect path swapped in a new ProtocolClient but never took
chat_rx, activity_rx, or delta_rx from it. After the first reconnect,
the event-driven UI pipeline was dead.
Fix by extracting spawn_event_forwarders() helper called on both
initial connect and reconnect. Also replaces lossy try_recv+sleep
polling with proper recv().await for push-based delivery.
* feat(protocol): enrich delta schema with all snapshot-visible fields
ClientJoined now carries input_muted, output_muted, is_server_query,
talk_power, talk_power_granted. ChannelAdded/ChannelUpdated now carry
has_password and needed_talk_power. ClientUpdated also carries
is_server_query, talk_power, talk_power_granted.
This prevents local snapshot drift where fabricated defaults could
hide password requirements, talk-power restrictions, or client type.
* refactor: remove dead SnapshotChanged variant end-to-end
SnapshotChanged is no longer emitted since the watchdog was refactored
to liveness-only. Removes the variant from SessionEvent, BridgeEvent,
and the Flutter switch statement. FRB bindings regenerated.
* fix(ci): regenerate license inventory and fix iOS submodule fetch
- Regenerate docs/security/license-inventory.md to match current lockfile
- Remove submodules: true from checkout (causes hard fail on private submodule)
- Add explicit git submodule update --init --depth=1 with || true fallback
- Check silero-coreml/Package.swift instead of directory existence
* fix(diag): record bridge events in diagnostics page
Connection lost/reconnecting/disconnected and iOS audio interruption
events now appear in the diagnostics dialog alongside existing error
snackbar entries.
* fix(diag): reduce audio callback sample verbosity to debug
The render callback diagnostic sample logged every 100 callbacks
(~2s) at INFO level, flooding the 256-entry release log buffer and
pushing out useful events. Changed to DEBUG so it only appears in
debug builds with the larger 4096-entry buffer.
* fix(diag): add timestamps to Rust diagnostic log entries
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
