feat(audio): desktop Silero ONNX VAD + Windows PTT modernization + MSVC CRT build fix (#37)
* 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(audio,protocol,ui): TC-2.3 + TC-10 + TC-13 + channel tree hierarchy
Five user-reported defects + one auto-test regression-catcher.
== TC-2.3: capability badge stuck at L0Focused on Korean Win 11 ==
Root cause: in WindowsRawInputBackend::start() (and the parallel
WindowsHookBackend), the worker thread's armed.store(ok, ...) only
ran AFTER GetMessageW returned (i.e. on WM_QUIT). During normal
arming the message pump runs forever, so armed stayed at its
initial false value, and descriptor() reported L0Focused even
though RegisterRawInputDevices had succeeded.
Fix: run_raw_input_loop and run_hook_loop now take armed as a
parameter and flip it to true inside the loop right after the
successful registration, before blocking on GetMessageW. The
outer setter is kept as a belt-and-braces clear-on-failure path.
Also drops the redundant outer 'Raw Input armed' / 'low-level
hook armed' log lines — the in-loop 'Raw Input devices
registered' / 'low-level hooks installed' messages already
convey arming success with full context.
New tests raw_input_backend_start_flips_armed_to_l2 and
hook_backend_start_flips_armed_to_l2 call real start(), sleep
80 ms, assert descriptor().level == L2GlobalHoldToTalk. Replaces
the previous #[ignore]'d real-start smoke test which never
asserted on the descriptor.
== TC-10: no-permission channel rejection invisible ==
Root cause 1: chanora_protocol::adapter::move_self_to used the
fire-and-forget send() on the client_move command. TS3 server
replies with a typed error event the adapter discarded, and
move_to_channel returned Ok regardless.
Root cause 2: even when chanora_core::voice_join detected the
non-confirmation via snapshot polling, the rolled-back error
flowed into the connect-form-area _error string which is hidden
post-connect. The user saw no feedback.
Fix:
* New ProtocolError::ServerRejected { code: u32, message: String }
carries the canonical TS3 error code per the official catalogue
at https://github.com/ReSpeak/tsdeclarations (Errors.csv).
* move_self_to now uses send_with_result, returns a MessageHandle.
The connection-task loop holds a pending_moves HashMap keyed by
MessageHandle, services StreamItem::MessageResult by looking up
and resolving the reply with either Ok or the typed
ServerRejected.
* Pending entries have a 3 s deadline so a server that never
replies doesn't leak the reply channel — expired entries fall
back to Ok and let the snapshot poll handle confirmation.
* voice_join short-circuits on ServerRejected (no need for the
full snapshot poll), still polls for confirmation as a
belt-and-braces fallback for legacy servers; on poll failure
emits ServerRejected with sentinel code 0x0001 (undefined).
* New BridgeError::ServerRejected mirror with the same fields;
CoreError → BridgeError mapping preserves the typed variant.
* Flutter _onJoinChannel shows a floating SnackBar with a
localised message selected by error code (channelJoinFailed*
l10n entries). 6 known codes mapped to specific messages
(insufficient permission, wrong password, channel full,
family limit, private channel, timeout); everything else
falls back to the server-supplied generic message.
== TC-13: mouse side-button capture only works on text field ==
The _PttBindingCaptureDialog wrapped its Column with a Listener
using the default HitTestBehavior.deferToChild. Pointer events
landing on the dialog's empty padding regions weren't claimed by
any child and so were never delivered to the Listener.
Fix: explicit HitTestBehavior.opaque so the entire dialog area
catches PointerDown events regardless of where the cursor sits.
== Channel tree hierarchy ==
Reported issue: tree rendered as flat list, no indication of
parent-child nesting. The bridge already carries the
field; the renderer just ignored it.
Fix in _SnapshotView: walk the (already DFS-sorted) channel list
and compute each row's depth from its parent's depth. Render
left-padding of depth * 18 dp. Cap depth at 6 to keep deep
hierarchies visually bounded; the cap plateaus silently (no
glyph, channel still tappable, data carries the real depth).
== Responsive layout ==
Connected layout is now LayoutBuilder-driven. Below 840 dp wide
(Material's tablet/desktop breakpoint) the original stacked
column layout is used (Voice Bar on top, channel tree below).
At 840 dp and above the layout becomes a side-by-side Row with
the Voice Bar pinned at 320 dp on the left and the channel tree
Expanded on the right.
Verification
- cargo check --workspace: clean.
- cargo test --workspace --lib: 80 / 0 / 1 (unchanged Linux total;
+2 new Windows-only tests not counted here).
- flutter analyze: clean (6 pre-existing Radio.groupValue infos).
- FRB bindings regenerated to expose BridgeError_ServerRejected.

fix(audio,windows): init_tx is SyncSender not Sender (windows-only build fix)
run_raw_input_loop / run_hook_loop signatures used Sender<bool> but the callers create the channel via sync_channel which returns SyncSender. Linux cross-check missed this because windows.rs is behind #[cfg(target_os = "windows")]. |

fix(audio,voice,log): six P0 issues from Korean Windows test
1. Voice Bar 'Leave voice' button removed entirely. TeamSpeak users are always in some channel; Discord/Mumble-style leave is the wrong model. To stop being heard / hearing, mute mic / speaker. To physically move, tap a different channel. The voiceLeave bridge call + _onLeaveVoice stay as dead code for now (marked unused) so existing tests/integrations don't break. 2. voice_join now confirms the move actually applied server-side by polling the snapshot for up to 1.5 s and matching our own client's channel against the requested one. If the server rejected the move (no permission, wrong password, channel full), voice_join rolls the selector back to in_channel=false and returns Err so the UI surfaces the failure instead of showing a fake 'joined' state. 3. ServerSnapshot + BridgeSnapshot gain own_client_id so the UI can identify our row without name-matching. find_own_in reads it directly. 4. set_self_muted now also clamps the TransmitModeSelector's hard_mute when input is muted server-side. Without this, the Opus encoder kept producing frames after setInputMuted(true), tsclientlib refused each one with 'Sending audio while muted', and the log grew to 200 MB on the Korean host. 5. tsclientlib WARN spam suppressed via tracing filter (tsclientlib=error). Belt-and-braces on top of fix 4. 6. Log file is now rotated at every launch (not just when >4 MiB). Two generations kept: chanora.log.1 (previous) and chanora.log.2 (the one before). The bug that produced 200 MB files was a chatty subsystem flooding a single session; the per-launch rotate keeps disk use bounded by what one session can produce in its lifetime. Bonus Windows fix (separate from the six but found in the same log): the Raw Input + Hook backends now signal readiness BEFORE blocking on GetMessageW. Previously init_tx.send was called after the loop returned (i.e. on WM_QUIT, which never happens during arming), so the main thread's 2 s readiness probe always timed out and the backend reported L0Focused even when registration succeeded. Both run_raw_input_loop and run_hook_loop now take an init_tx parameter and call report!(true) right after a successful registration, and report!(false) on every early-fail return. cargo check --workspace: clean. cargo test --workspace --lib: 80 passed / 0 failed / 1 ignored. flutter analyze: clean (6 pre-existing Radio.groupValue infos). |

test(audio,ptt): comprehensive Windows P0 unit-test suite (L0-L11)
Layered test coverage for the Windows PTT subsystem ahead of the
v1.0.0-rc.8 official release sign-off.
L0 (refactor)
- Extract three pure-logic dispatchers from the existing WndProc /
LowLevelKeyboardProc / LowLevelMouseProc bodies in
crates/chanora_audio/src/ptt_backends/windows.rs:
dispatch_raw_input(ctx, &RAWINPUT)
dispatch_hook_keyboard(ctx, wparam, &KBDLLHOOKSTRUCT)
dispatch_hook_mouse(ctx, wparam, &MSLLHOOKSTRUCT)
Each takes a small Context (AtomicBinding + AudioTransmitGate +
flags) and is callable without spinning up any Win32 plumbing.
The real Win32 procs unchanged structurally; they unpack lparam
and forward to the dispatchers. AtomicBinding / RawInputContext
/ HookContext / resolve_binding are now pub(crate) so the
in-file test module can drive them.
L1 — windows_keymap full-table sweep (+13 tests)
Every key_label_to_vk arm, all A-Z + a-z, all 0-9, F1-F20,
navigation, modifiers, OEM punctuation, numpad. Exhaustive
mouse_label_to_button cases including the 0x08 / 0x10 /
unknown-bitmask fallbacks.
L2 — AtomicBinding lock-free correctness
store/read round-trip, clear(), Default = zeros, single-writer
/ single-reader concurrency, many-readers / single-writer.
L3 — resolve_binding dispatcher tests
All PttInputClass variants, well-known labels, unknown-label
fallback, mismatched class+label rejection, mouse bitmask
resolution.
L4 — Backend state-machine
Both WindowsRawInputBackend and WindowsHookBackend:
descriptor() pre-arm vs post-arm (L0Focused -> L2/L3), start()
with None binding rejection, rebind() in-place, stop()
clears + idempotent, stop() after stop() no-op.
L5 — dispatch_raw_input table
Keyboard match/non-match, key-down/key-up via Flags & 0x01,
no-binding short-circuit, mouse XBUTTON1/XBUTTON2 down/up
matching the bound button, unhandled HID type. RAWINPUT structs
built via mem::zeroed plus field-fill, owning the unsafe in
the test layer where it belongs.
L6 — dispatch_hook_keyboard + dispatch_hook_mouse
WM_KEYDOWN / WM_KEYUP / WM_SYSKEYDOWN / WM_SYSKEYUP for the
keyboard path, WM_XBUTTONDOWN / WM_XBUTTONUP for the mouse
path. Same shape as L5.
L7 — Privacy invariant (crates/chanora_audio/tests/ptt_privacy.rs)
New cross-platform integration test installs a custom
tracing_subscriber Layer that records every emitted event's
target + field names. Exercises the public PTT API plus (on
Windows) the backend factory. Asserts no field name in the
banned list (vk, scan_code, keysym, key_label, bound_key,
binding, platform_key, VKey, wVk, wScan, kbflags, mouseflags)
is ever emitted and every field belongs to the DEC-027
allow-list. Adds tracing-subscriber as a dev-dependency on
chanora_audio.
L8 — Full-chain integration in core/chanora_core/src/ptt.rs
Windows-only mod windows_full_chain_tests:
zero-tail full chain (synchronous)
default-tail full chain (200 ms wait then off)
mid-press rebind abandons in-flight press
L9/L10/L11 — tools/windows-smoke.cmd + tools/windows-smoke.md
Batch smoke script + operator doc. cargo build, flutter build,
artifact existence + size checks, headless launch with stderr
capture, bridge-initialised log assertion. Distinct exit codes
per failure step. Doc explains invocation + common failure
modes.
Verification (Linux)
- cargo check --workspace: clean.
- cargo test --workspace: 78 passed / 0 failed / 3 ignored.
76 cross-platform unit tests (unchanged) plus the new
ptt_privacy integration test plus one new ignored portal smoke
test.
The Windows-gated tests (~49 new) compile and run on the Korean
Windows 11 host where they belong; cross-compile from Linux is
not configured locally. The smoke script is the production
acceptance gate for rc.8 on Windows.
Deviations from the original plan are minor (single ignored
real-runtime test rather than per-platform attribute, L7 uses
public API rather than pub(crate) dispatchers, dispatchers live
inside windows.rs rather than a sibling module) and documented
in the subagent report.

fix(audio,windows): adapt Raw Input + hook backends to windows-rs 0.54 API shape
Initial Task C commit (
|
||

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.

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
------------

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.

creation under granted permission, GlobalShortcuts CreateSession +
BindShortcuts) is queued for the platform owners' reference hosts
per `staged-release-plan.md`.
