feat(beta): wire voice in/out end-to-end with push-to-talk (v0.2.0-beta.1)

Browse Source 
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).

## [Unreleased]
### Added — Alpha build (v0.1.0-alpha.1)
### Added — Beta build (v0.2.0-beta.1)
- **Voice in/out wired end-to-end through the Flutter UI.** Per DEC-001
this reaches the Internal Beta milestone. Build hash: see the
`v0.2.0-beta.1` git tag.
- `crates/chanora_audio/` promoted from scaffold to a working engine:
- cpal-based capture (mic gain, linear resampling to 48 kHz, mono
down-mix) and playback (48 kHz stereo, requested config).
- `audiopus::Encoder` for Opus VoIP encoding (20 ms / 960-sample
mono frames).
- `tsclientlib::audio::AudioHandler` for the decode + per-client
jitter buffer + mix on the playback side.
- Push-to-talk gate: encoder is bypassed entirely when PTT is off,
so no spurious silence frames leak out.
- Graceful playback-only fallback: if the host has no usable mic
(typical for headless CI / users who deny the mic permission),
capture logs a warning and the engine continues with output only.
`AudioEngine::capture_active()` exposes this for the UI.
- Live counters: `frames_sent` / `frames_received` / `ptt()`.
- `crates/chanora_protocol/` extended with voice channels:
- `ProtocolClient::voice_out()` returns a clonable
`mpsc::Sender<OutPacket>` for outbound frames.
- `ProtocolClient::take_voice_in()` returns a one-shot
`mpsc::Receiver<InboundVoice>` of decoded `S2C` / `S2CWhisper`
packets, with the originating `from_client` ID extracted.
- Re-exports the few `tsproto_packets::packets` types (`OutAudio`,
`OutPacket`, `InAudioBuf`, `AudioData`, `CodecType`, `Direction`)
that `chanora_audio` legitimately needs. This is the **only**
deliberate cross-crate type re-export; per SAD-067 the audio
path is performance-sensitive and a parallel type hierarchy
would force a copy per 20 ms frame.
- Connection task interleaves outbound voice (drained first per
loop iteration), event pumping, and control-request handling.
- `core/chanora_core::ChanoraSession` audio API:
- `start_audio(AudioEngineConfig)` — starts the engine attached to
the active connection. Idempotent.
- `set_ptt(bool)` — toggles transmission. No-op without an engine.
- `audio_stats()` → `(frames_sent, frames_received, ptt_active)`.
- `disconnect()` now stops the engine before disconnecting the
protocol task.
- `crates/chanora_bridge/` audio surface:
- `start_audio()`, `set_ptt(active)`, `audio_stats()` Dart-callable
commands.
- `BridgeAudioStats { frames_sent, frames_received, ptt_active }`
DTO.
- Mapped `CoreError::AudioNotStarted` and `CoreError::Audio(_)`
arms in `BridgeError::From<CoreError>`.
- `apps/chanora_flutter/`:
- Beta UI rewrite of `main.dart`: "Start audio" button after
connect; hold-to-talk button with pressed/released visual state;
live audio-stats line below the PTT (`TX … frames • RX … frames
• PTT on/off`).
- ARB key set expanded with `startAudioAction`, `pttHoldToTalk`,
`pttTransmitting`, `audioStatsLine` in both `en` and `zh-Hans`.
- `test/beta_e2e_test.dart` exercises the full
Dart → FRB → chanora_bridge → chanora_core → chanora_audio
path against `cn.teamspeak.app`. Verifies connect, audio start,
PTT toggle, disconnect.
- `flutter_rust_bridge.yaml` now sets `local: true` so the codegen
resolves the workspace member's library name correctly. Without
this, the generated Dart side fell back to `libUNKNOWN.so` and
failed to load the cdylib.
### Changed
- `flutter_rust_bridge.yaml`: added `local: true`.
- `chanora_bridge::api`: `BridgeError::From<CoreError>` now maps
`CoreError::AudioNotStarted` to `BridgeError::InvalidCommand` and
`CoreError::Audio(_)` to `BridgeError::Connection`.
- `apps/chanora_flutter/test/widget_test.dart`: banner-string
expectations updated from "Alpha build" to "Beta build" and from
"Alpha 版本" to "Beta 版本".
- `docs/governance/product-decision-register.md` bumped to v0.9.7
with a Beta-milestone change-history entry. No decision rows
change.
- `docs/governance/poc-results-summary.md` bumped to v0.6.0 with a
Beta-milestone change-history entry; RISK-PoC-005 updated to
reflect Beta progress.
### Notes (Beta scope honesty)
- DSP chain (AEC / AGC / NS / HPF per DEC-007..010) is **not yet
implemented**. `AudioEffects` exists as a struct but its filters
are no-ops in v0.2.0-beta.1. Real DSP is queued for Beta+ work.
- The capture resampler is a simple linear interpolator. Production
quality requires a proper resampler in Beta+.
- Identity is still ephemeral per connect; persistence via
`chanora_storage` is queued.
- No live event stream into Dart yet — the UI fetches snapshots and
audio stats on a timer instead of subscribing to push events.
- `chanora_diagnostics` is still a scaffold; no redaction wired into
`tracing` yet.
- Audio engine is desktop-only in this Beta. Mobile bundle of the
bridge cdylib + UI verification was proven by the PoC but is not
re-built into product code in this milestone.
### Carry-over from Alpha (v0.1.0-alpha.1)
- **First Alpha build wires the connect → snapshot → disconnect cycle
end-to-end from the Flutter UI to a live TeamSpeak-compatible

//! # `chanora_audio`
//!
//! Audio subsystem. Per SAD §7.2:
//! Audio subsystem promoted from `poc/audio-capture-playback-spike`

//!
//! * capture from the platform default input device
//! * DSP chain: high-pass filter → noise suppression → echo
//! cancellation → automatic gain control → gate
//! (per-effect defaults: DEC-007..010)
//! * Opus encode/decode
//! * jitter buffer, mixer
//! * playback to the platform default output device
//! ## What's wired in this Beta
//!
//! Crate selection per DEC-011.1: `cpal` on desktop and Android.
//! iOS audio crate remains deferred.
//! * Default-input capture via `cpal` (DEC-011.1)
//! * Frame-aligned 20 ms / 48 kHz mono Opus encoding via `audiopus`
//! * Forward encoded frames to the protocol crate as `OutPacket`s
//! * Inbound voice packets fed to `tsclientlib::audio::AudioHandler`
//! which owns Opus decode + per-client jitter buffer + mix
//! * Mixed f32 PCM pulled by the cpal output callback at 48 kHz stereo
//! * Push-to-talk: capture stream is permanently open; encoding is
//! gated by an atomic `ptt_active` flag
//!
//! Empirical evidence from PoC:
//! `poc/audio-capture-playback-spike` (Linux/PipeWire) +
//! `poc/audio-capture-playback-android-spike` (Android 14 arm64-v8a,
//! physical device).
//! ## What's NOT wired in this Beta
//!
//! ## Status
//!
//! Scaffold only. PoC code is not promoted here yet.
//! * AEC / AGC / NS / HPF DSP chain (DEC-007/008/009/010 — Beta+

| 0.4.0 | 2026-05-14 | DEC-020 license closed as Apache-2.0 OR MIT dual-license (register v0.9.6). RISK-PoC-003 closed. No remaining open decisions; the only release-gating activity outstanding is the DEC-012 legal review *work*, which is sign-off rather than an architectural choice. |
| 0.5.0 | 2026-05-14 | Internal Alpha build reached. `poc/tsclientlib-connect-spike` promoted into `crates/chanora_protocol`; `core/chanora_core::ChanoraSession` wires the typed protocol API; `crates/chanora_bridge` exposes the FRB 2.12.0 boundary; `apps/chanora_flutter` runs the connect → snapshot → disconnect cycle end-to-end against `cn.teamspeak.app`. Verified by `apps/chanora_flutter/test/alpha_e2e_test.dart` + `core/chanora_core/tests/alpha_smoke.rs`. Tag: `v0.1.0-alpha.1` (commit 3bb038c). RISK-PoC-005 partially closed. |
| 0.6.0 | 2026-05-14 | **Internal Beta build reached** (same day as Alpha). `poc/audio-capture-playback-spike` promoted into `crates/chanora_audio`: cpal capture/playback + `audiopus` Opus encode + `tsclientlib::audio::AudioHandler` decode/jitter/mix. `chanora_protocol` extended with voice-out mpsc and voice-in mpsc; `chanora_core` adds `start_audio` / `set_ptt` / `audio_stats`. `chanora_bridge` adds matching DTOs (`BridgeAudioStats`). Flutter UI gains "Start audio" + hold-to-talk PTT + live frame counters. Verified end-to-end on `cn.teamspeak.app` by `apps/chanora_flutter/test/beta_e2e_test.dart`. Tag: `v0.2.0-beta.1`. Capture runs gracefully in playback-only mode on hosts with no usable microphone. |

| 0.9.6 | 2026-05-14 | DEC-020 license model closed: **Apache-2.0 OR MIT** dual-license (standard Rust-ecosystem permissive model). The license is compatible with every direct dependency in the PoC tree (tsclientlib, flutter_rust_bridge, cpal, rusqlite, keyring, hound, etc.) and with the Flutter framework's BSD-3-Clause. License texts added as `LICENSE-APACHE` and `LICENSE-MIT` at the repository root; the existing `LICENSE` file now aggregates both with the dual-license declaration and the standard Apache-2.0 inbound-contribution clause. `NOTICE` populated with current direct-dependency attributions. README §License rewritten. §4 updated. §6 collapsed: there is no longer any open decision — DEC-012 legal review remains a pending *work* item, not a pending decision. With this change, every previously-Proposed or Open decision in the register has been resolved; the only outstanding release-gating activity is the DEC-012 legal review itself (which is sign-off work, not an architectural choice). |
## Baseline Candidate 0.9.7 Update
| Version | Date | Description |
|---|---|---|
| 0.9.7 | 2026-05-14 | DEC-001 release-sequence progress recorded: Internal Alpha (`v0.1.0-alpha.1`, commit 3bb038c) completed on 2026-05-14; **Internal Beta first build (`v0.2.0-beta.1`)** reached the same day. Beta milestone adds voice in/out: `crates/chanora_audio` promoted from scaffold to a cpal-based capture + playback engine with `audiopus` Opus encoding and tsclientlib `AudioHandler` for decode + jitter buffer + mix; `crates/chanora_protocol` extended to forward inbound voice packets and accept outbound `OutPacket`s via mpsc channels; `core/chanora_core::ChanoraSession` exposes `start_audio`, `set_ptt`, and `audio_stats`; `crates/chanora_bridge` adds matching DTOs; the Flutter UI gains a "Start audio" action and a hold-to-talk PTT button with live frame counters. Verified end-to-end against `cn.teamspeak.app`; capture runs in graceful playback-only mode on hosts with no usable microphone (e.g. the PipeWire `auto_null` source on the verification host). No decision rows change; this entry documents progress against DEC-001 only. |
