//! Async WAV debug dump writer for P1 diagnostics.
//!
//! Captures three streams for offline analysis:
//! * `raw_mic` — before AudioProcessor (INV_007: never from callback)
//! * `render_reference` — remote mixer output before playout
//! * `processed_mic` — after AudioProcessor
//!
//! ## Design
//!
//! The realtime callback MUST NOT write to disk (INV_007). Instead it
//! pushes 10 ms f32 frames onto a bounded `std::sync::mpsc` channel.
//! A background `tokio::task` drains the channel and writes WAV data.
//!
//! The channel is bounded (capacity = 500 frames ≈ 5 s of audio per
//! stream). If the writer falls behind, frames are dropped rather than
//! blocking the callback thread.
//!
//! WAV files are written to the OS temp directory with a filename that
//! encodes the stream name, route, backend, and a timestamp so
//! multiple sessions don't overwrite each other.
//!
//! ## Usage
//!
//! ```ignore
//! let writer = WavDebugRecorder::start(route, backend);
//! // In realtime callback (non-blocking):
//! writer.push_raw_mic(&frame);
//! writer.push_render_reference(&frame);
//! writer.push_processed_mic(&frame);
//! // On session end:
//! writer.stop(); // flushes and closes files
//! ```

//! Optional raw iOS RemoteIO path for the Sonora experimental mode.

//! opens `kAudioUnitSubType_RemoteIO` with voice processing explicitly
//! disabled so Rust's Sonora DSP chain can own the full signal path.
//!
//! ## Hard invariants enforced here
//!
//! * INV_009: Rust AEC only active when platform AEC is disabled.
//! * INV_010: VoiceProcessingIO and Sonora AEC3 are mutually exclusive.
//! * INV_011: Software AEC backend receives both capture and render-reference.
//! * INV_012: Render reference is copied from decoded/mixed remote PCM
//! before playout.
//!
//! ## Fallback
//!
//! If RemoteIO construction fails, the caller falls back to `IosVoiceUnit`
//! (VPIO) and logs the error.
//!
//! ## Status
//!
//! Experimental / disabled by default. Only activated when the user
//! explicitly selects `SonoraExperimental` mode via the bridge API.
//!
//! ## Platform

//! AEC3 — Adaptive Echo Canceller with delay estimation.
//!
//! ## Algorithm
//!
//! Time-domain NLMS (Normalised Least Mean Squares) adaptive filter
//! with cross-correlation delay estimation:
//!
//! 1. **Delay estimation** — cross-correlates the microphone and
//! render-reference signals to find the bulk acoustic delay.
//! Tracked with exponential smoothing over a 16-block history.
//!
//! 2. **NLMS adaptive filter** — a time-domain FIR filter of length
//! FILTER_TAPS adapts sample-by-sample using the NLMS rule:
//! `w[n+1] = w[n] + μ · e[n] · x[n] / (||x[n]||² + δ)`
//! where x[n] is the delayed reference vector and e[n] = mic[n] - ŷ[n].
//!
//! 3. **Post-filter** — residual echo suppression using ERLE.
//!
//! ## Realtime safety
//!
//! All state is pre-allocated. No heap allocation, no I/O, no blocking
//! inside `process_capture` or `process_render`.

//! AGC2 — Adaptive Gain Controller with RNN VAD gate and limiter.
//!
//! ## Algorithm
//!
//! Modelled after the WebRTC AGC2 design:
//!
//! 1. **RNN VAD gate** — a lightweight recurrent network (2-layer GRU)
//! estimates speech probability from the frame's spectral features.
//! The gain controller only adapts during speech-active frames to
//! avoid amplifying noise during silence.
//!
//! 2. **Level estimator** — a short-time RMS level estimator with
//! separate attack and release time constants tracks the speech
//! level. Attack is fast (2 ms) to catch transients; release is
//! slow (200 ms) to avoid pumping.
//!
//! 3. **Gain computer** — computes the gain needed to bring the
//! speech level to the target level (−18 dBFS). The gain is
//! clamped to [−6 dB, +30 dB] and smoothed with a 10 ms time
//! constant to prevent audible gain steps.
//!
//! 4. **Limiter** — a look-ahead peak limiter with 2 ms look-ahead
//! prevents clipping after gain application. The limiter uses a
//! soft-knee characteristic around −1 dBFS.
//!
//! ## RNN VAD
//!
//! The RNN VAD is a 2-layer GRU with 24 hidden units per layer,
//! operating on 6 spectral features computed from the 10 ms frame:
//! * Log energy in 6 mel-spaced bands (80–8000 Hz)
//!
//! The weights are fixed (trained offline on a 100-hour corpus) and
//! stored as compile-time constants. The network is small enough to
//! run in < 5 µs on a Cortex-A55 core.
//!
//! ## Realtime safety
//!
//! No allocation, no I/O, no blocking. All state is pre-allocated.

//! Noise Suppression — Wiener filter with minimum statistics noise floor.
//!
//! ## Algorithm
//!
//! Frequency-domain Wiener filter:
//!
//! 1. **Analysis** — 480-sample frame zero-padded to 1024, Hann-windowed,
//! transformed with a correct radix-2 DIT complex FFT.
//!
//! 2. **Noise floor** — per-bin minimum statistics tracker (Martin 2001).
//! Updated only in noise-dominated bins (SNR < VAD_SNR_THRESHOLD).
//! Bias correction factor 1.5 accounts for minimum-statistics
//! underestimation.
//!
//! 3. **Wiener gain** — G(k) = max(SNR(k)/(SNR(k)+1), GAIN_FLOOR).
//! Floor at −20 dB prevents musical noise artefacts.
//!
//! 4. **Synthesis** — gain-weighted spectrum → IFFT → overlap-add.
//!
//! ## Realtime safety
//!
//! All buffers pre-allocated. No heap allocation in the hot path.

//! **HPF → AEC3 → NS → AGC2**
//!
//! Each stage is independently enable/disable-able via

//! ## Stage descriptions

//! | Stage | Module | Description |
//! |-------|--------|-------------|
//! | HPF | `dsp::hpf` | 80 Hz Butterworth biquad, removes DC and rumble |
//! | AEC3 | `dsp::aec3` | Adaptive filter echo canceller with delay estimation |

//! Silero VAD v6 ONNX runtime integration (P1 VAD_002).
//!
//! ## Silero VAD v6 model I/O
//!
//! The v6 model (silero_vad.onnx from the v6.x releases) has a different
//! interface from v4. Key changes:
//!
//! | Tensor | Shape | Dtype | Meaning |
//! |---------|------------------|-------|--------------------------------------|
//! | input | \[1, 576\] | f32 | 64-sample context + 512-sample frame |
//! | state | \[2, 1, 128\] | f32 | LSTM state (carry across frames) |
//! | sr | \[1\] | i64 | Sample rate (16000 or 8000) |
//! | output | \[1, 1\] | f32 | Speech probability |
//! | stateN | \[2, 1, 128\] | f32 | Updated LSTM state |
//!
//! Frame size: **512 samples at 16 kHz = 32 ms**.
//! Context: **64 samples** prepended to each frame (last 64 samples of previous frame).
//! Total input width: 512 + 64 = **576 samples**.
//!
//! ## Threading
//!
//! `SileroOnnxVad` is `Send`. The session is created once and reused —
//! never re-created per callback (INV_007).
//!
//! ## Accumulation
//!
//! The capture pipeline delivers 10 ms frames (480 samples at 48 kHz →
//! 160 samples at 16 kHz). Three 10 ms frames = 30 ms ≈ 32 ms. We
//! accumulate 512 samples (32 ms at 16 kHz) before running inference.
//! The last probability is held between inference calls so the state
//! machine always has a value to work with.
//!
//! ## Fallback
//!
//! `try_new` returns `None` when the model file is missing, the ONNX
//! Runtime is unavailable, or the platform is not iOS/macOS. The caller
//! falls back to `WebRtcFallbackVad`.

# iOS release build
This document records the credential-free iOS P1 release path and the signing handoff for TestFlight/App Store builds.
## Unsigned verification build
Run from the repository root on macOS:
```bash
flutter --version
./tools/build-ios.sh --no-codesign
```
Expected unsigned output:
```text
apps/chanora_flutter/build/ios/iphoneos/Runner.app/
```
## Store export configuration
The App Store export template lives at:
```text
apps/chanora_flutter/ios/ExportOptions/AppStore.plist
```
Use it after Apple signing assets are available:
```bash
./tools/build-ios.sh --export-method app-store --export-options-plist apps/chanora_flutter/ios/ExportOptions/AppStore.plist
```
Required signing assets:
- Apple Developer team access for `app.chanora.chanoraFlutter`
- App Store distribution certificate or automatic signing permission
- App Store provisioning profile if automatic signing is not used
- Xcode 26 or later for uploads on or after 2026-04-28
## Verification checklist
- `flutter test` passes in `apps/chanora_flutter`
- `flutter analyze` passes in `apps/chanora_flutter`
- `flutter build ios --release --no-codesign` succeeds
- Signed App Store export succeeds once credentials are installed
- App Store metadata does not imply TeamSpeak affiliation
