rUv f49c722764 chore(repo): rename rust-port/wifi-densepose-rs → v2/ (flatten to one level) (#427)
The Rust port lived two directories deep (rust-port/wifi-densepose-rs/)
without any sibling under rust-port/ that warranted the extra level.
Move the whole workspace up to v2/ to match v1/ (Python) at the same
depth and shorten every cd / build command across the repo.

git mv preserves history for all tracked files. 60 files updated for
path references (CI workflows, ADRs, docs, scripts, READMEs, internal
.claude-flow state). Two manual fixes for relative-cd paths in
CLAUDE.md and ADR-043 that became wrong after the depth change
(cd ../.. → cd ..).

Validated:
- cargo check --workspace --no-default-features → clean (after target/
  nuke; the gitignored target/ was carried by the OS rename and had
  hard-coded old paths in build scripts)
- cargo test --workspace --no-default-features → 1,539 passed, 0 failed,
  8 ignored (same totals as pre-rename)
- ESP32-S3 on COM7 → still streaming live CSI (cb #40300, RSSI -64 dBm)

After-merge follow-up: contributors should `rm -rf v2/target` once and
let cargo regenerate from the new path.

# wifi-densepose-ruvector
RuVector v2.0.4 integration layer for WiFi-DensePose — ADR-017.
This crate implements all 7 ADR-017 ruvector integration points for the
signal-processing pipeline and the Multi-AP Triage (MAT) disaster-detection
module.
## Integration Points
| File | ruvector crate | What it does | Benefit |
|------|----------------|--------------|---------|
| `signal/subcarrier` | ruvector-mincut | Graph min-cut partitions subcarriers into sensitive / insensitive groups based on body-motion correlation | Automatic subcarrier selection without hand-tuned thresholds |
| `signal/spectrogram` | ruvector-attn-mincut | Attention-guided min-cut gating suppresses noise frames, amplifies body-motion periods | Cleaner Doppler spectrogram input to DensePose head |
| `signal/bvp` | ruvector-attention | Scaled dot-product attention aggregates per-subcarrier STFT rows weighted by sensitivity | Robust body velocity profile even with missing subcarriers |
| `signal/fresnel` | ruvector-solver | Sparse regularized least-squares estimates TX-body (d1) and body-RX (d2) distances from multi-subcarrier Fresnel amplitude observations | Physics-grounded geometry without extra hardware |
| `mat/triangulation` | ruvector-solver | Neumann series solver linearises TDoA hyperbolic equations to estimate 2-D survivor position across multi-AP deployments | Sub-5 m accuracy from ≥3 TDoA pairs |
| `mat/breathing` | ruvector-temporal-tensor | Tiered quantized streaming buffer: hot ~10 frames at 8-bit, warm at 57-bit, cold at 3-bit | 13.4 MB raw → 3.46.7 MB for 56 sc × 60 s × 100 Hz |
| `mat/heartbeat` | ruvector-temporal-tensor | Per-frequency-bin tiered compressor for heartbeat spectrogram; `band_power()` extracts mean squared energy in any band | Independent tiering per bin; no cross-bin quantization coupling |
## Usage
Add to your `Cargo.toml` (workspace member or direct dependency):
```toml
[dependencies]
wifi-densepose-ruvector = { path = "../wifi-densepose-ruvector" }
```
### Signal processing
```rust
use wifi_densepose_ruvector::signal::{
mincut_subcarrier_partition,
gate_spectrogram,
attention_weighted_bvp,
solve_fresnel_geometry,
};
// Partition 56 subcarriers by body-motion sensitivity.
let (sensitive, insensitive) = mincut_subcarrier_partition(&sensitivity_scores);
// Gate a 32×64 Doppler spectrogram (mild).
let gated = gate_spectrogram(&flat_spectrogram, 32, 64, 0.1);
// Aggregate 56 STFT rows into one BVP vector.
let bvp = attention_weighted_bvp(&stft_rows, &sensitivity_scores, 128);
// Solve TX-body / body-RX geometry from 5-subcarrier Fresnel observations.
if let Some((d1, d2)) = solve_fresnel_geometry(&observations, d_total) {
println!("d1={d1:.2} m, d2={d2:.2} m");
}
```
### MAT disaster detection
```rust
use wifi_densepose_ruvector::mat::{
solve_triangulation,
CompressedBreathingBuffer,
CompressedHeartbeatSpectrogram,
};
// Localise a survivor from 4 TDoA measurements.
let pos = solve_triangulation(&tdoa_measurements, &ap_positions);
// Stream 6000 breathing frames at < 50% memory cost.
let mut buf = CompressedBreathingBuffer::new(56, zone_id);
for frame in frames {
buf.push_frame(&frame);
}
// 128-bin heartbeat spectrogram with band-power extraction.
let mut hb = CompressedHeartbeatSpectrogram::new(128);
hb.push_column(&freq_column);
let cardiac_power = hb.band_power(10, 30); // ~0.82.0 Hz range
```
## Memory Reduction
Breathing buffer for 56 subcarriers × 60 s × 100 Hz:
| Tier | Bits/value | Size |
|------|-----------|------|
| Raw f32 | 32 | 13.4 MB |
| Hot (8-bit) | 8 | 3.4 MB |
| Mixed hot/warm/cold | 38 | 3.46.7 MB |
