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

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

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

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

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

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

EdisonJwa 03f5d6bca3 fix(p0): close three P0 coverage gaps after rc.5 audit
Audited every `Priority: P0` row in `docs/requirements/{sysrs,srs}.md`
against the live code. Three items needed work; this commit closes
all three.

Gap A — SysRS-262 + SysRS-282 (screen-reader semantics + accessible
labels for the PTT control)
-------------------------------------------------------------------

The Flutter PTT control is a custom `Listener` over a `Container`
— not a built-in `Button`, so the platform accessibility tree had
no idea it was an interactive control. Screen readers
(VoiceOver, TalkBack, NVDA, Orca) would have read the visible text
without announcing the control role or its toggled state.

Wrap the Listener in a `Semantics(button: true, toggled: _pressed,
label: …, hint: …, excludeSemantics: true)` so the platform
accessibility tree carries the right role, the current state
("Hold to talk" / "Transmitting"), and a usage hint. The
`excludeSemantics: true` argument suppresses the duplicate child
nodes the Container + Row + Icon + Text would otherwise generate
on top of our explicit label.

SysRS-263 (no colour-only state) is preserved: the visible label
and the mic icon already differentiate the two states without
relying on the colour transition.

New ARB key `pttHoldToTalkSemanticsHint` in `app_en.arb` and
`app_zh.arb`.

Gap B — SRS-198 (macOS async permission re-check)
-------------------------------------------------

The macOS backend queried `query_permission()` once at
construction and never re-checked. That violates SRS-198's
"upgrade to the appropriate Global level only after the user
grants the required permission" — once Chanora is running, a
runtime grant must lift the descriptor from `L0Focused` to a
Global level without an app restart.

Substantive rewrite of `crates/chanora_audio/src/ptt_backends/macos.rs`:

  * `permission: PermissionState` becomes `permission: Arc<AtomicU8>`,
    enabling cross-thread updates without a Mutex.
    `PermissionState::{to_u8, from_u8}` carry the encoding.
  * The backend owns a `tokio::sync::watch::Sender<PttBackendDescriptor>`
    and overrides `DesktopPttBackend::descriptor_watch()` to hand
    out subscribers; `chanora_core::ChanoraSession::start_audio`
    already forwards transitions to `SessionEvent::PttCapability`.
  * `start()` spawns a `chanora-perm-watch` OS thread that polls
    `query_permission()` every 1.5 s and republishes the
    descriptor on every transition. Polling rather than KVO /
    notifications because Input-Monitoring has no public
    change-notification API on macOS; 1.5 s is sufficient for a
    user grant + return-to-Chanora cycle.
  * `rebind()` also republishes the descriptor so a
    `keyboard → mouse-side-button` change updates the badge.
  * Six new unit tests on the platform-independent
    `build_descriptor` and the atomic encoding contract. They
    only compile under `target_os = "macos"` (consistent with
    the rest of the module), so the Linux dev-host workspace
    test count is unchanged.

`query_permission()` itself still returns `Undetermined` until
the IOKit live link lands in the macOS platform-verification
commit; the re-query loop will engage the upgrade path
automatically the moment that function returns real values.

Gap C — SRS-200 (Linux mouse-side-button portal-dependence)
-----------------------------------------------------------

`desktop-ptt-architecture.md` §5.3 already described the
heuristic classifier. Added one explicit sentence stating that
Linux mouse-side-button support is *portal-dependent*: Chanora
never claims a fixed Mouse4/Mouse5 binding on Linux; the portal
decides what inputs it accepts in the current session, and the
classifier degrades to `keyboard` whenever the portal's
description does not contain "mouse". This matches the SRS-200
text verbatim and removes the ambiguity over what "Linux
support follows the portal" means in practice.

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

  * `cargo test --workspace` (with `CHANORA_DISABLE_KEYRING=1`):
    all 67 Linux-side tests green (unchanged). The new macOS
    unit tests count under `target_os = "macos"` only — they
    will report once the macOS reference host runs `cargo test`.
  * `cargo deny check`: advisories ok, bans ok, licenses ok,
    sources ok.
  * `flutter analyze`: clean (no new accessibility warnings).
  * Linux release bundle builds clean.

P0 audit summary
----------------

After this commit every Priority: P0 row in `sysrs.md` and
`srs.md` has a concrete implementation. The remaining open items
are all live verification, not code:

  * Per-platform live PTT traces on Windows / macOS reference
    hosts (RR-PTT-001..003, RR-PTT-008) — hosts unavailable
    locally; queued for platform owners.
  * Linux GNOME-Wayland live trace (RR-PTT-004) — implemented
    in rc.5; awaiting live host trace.
  * Linux non-tested compositor fallback trace (RR-PTT-005) —
    Open.
  * Diagnostic-export key-leak inspection (RR-PTT-006) — Open
    but trivially testable on any host with PTT bound.
  * DEC-012 legal review — engineering hand-off complete since
    rc.2.

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

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

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

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

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

Trait surface (cross-cutting):

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

`Cargo.toml` (Linux-only):

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

Tests
-----

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Flutter
-------

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

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

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

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

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

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

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

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

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

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

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

Tests
-----

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

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

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

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

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

Hardening
---------

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

EdisonJwa 974dda9601 feat(scaffold): create product workspace + Rust crates + Flutter app
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.
