+//! 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
+//! ```

+//! 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.
