Rust Sensing Server v0.1.0 - WiFi-DensePose

Introduction

This release replaces the entire Python backend stack (FastAPI HTTP server + WebSocket server + mock server, ~2.7GB of Python dependencies) with a single 2.1MB Rust binary (sensing-server.exe). The server provides full DensePose-compatible API endpoints, dual WebSocket streams, WiFi-derived pose estimation with 17 COCO keypoints, and static UI file serving - all from one process.

The Rust server integrates the RuVector signal processing pipeline (5 crates) and supports three data sources: ESP32 CSI hardware, Windows WiFi RSSI, and simulation mode with automatic detection at startup.

Capabilities

Single Binary, Full Stack

  • HTTP REST API on port 8080 - all DensePose-compatible endpoints
  • Pose WebSocket on port 8080 (/api/v1/stream/pose) - real-time pose data
  • Sensing WebSocket on port 8765 (/ws/sensing) - raw CSI sensing updates
  • Static UI server on port 8080 (/ui/*) - serves the entire web UI
  • UDP listener on port 5005 - receives ESP32 CSI binary frames (ADR-018 format)

REST Endpoints

Endpoint Description
GET /health/live Liveness probe with uptime
GET /health/ready Readiness probe
GET /health/version Server version info
GET /health/health Full health status
GET /health/metrics System metrics
GET /api/v1/info Server info, features, source
GET /api/v1/pose/current Current pose (persons, keypoints, bbox)
GET /api/v1/pose/stats Detection statistics
GET /api/v1/pose/zones/summary Zone occupancy summary
GET /api/v1/stream/status WebSocket stream status

WiFi-Derived Pose Estimation

  • Generates 17 COCO-format keypoints (nose, eyes, ears, shoulders, elbows, wrists, hips, knees, ankles)
  • Keypoint positions derived from WiFi signal properties
  • Bounding box as {x, y, width, height} (UI-compatible format)
  • Confidence scores from WiFi sensing classification

Data Sources (Auto-Detected)

  1. ESP32 CSI - UDP binary frames with 56 subcarriers
  2. Windows WiFi - netsh RSSI polling
  3. Simulation - Synthetic CSI with breathing/motion patterns

Status Update: ADR-022 Multi-BSSID Pipeline Integration

Several items from this release checklist are being addressed by the ADR-022 Windows WiFi Enhanced Fidelity work (branch: feat/windows-wifi-enhanced-fidelity):

Completed (Issue #46)

Checklist Item Status Details
Wire up RuVector crates for SOTA signal processing DONE 8-stage pure-Rust pipeline in wifi-densepose-wifiscan crate (125 tests, ~12M frames/sec release). Stages: predictive gating, attention weighting, spatial correlation, motion estimation, breathing extraction, quality gate, fingerprint matching, orchestration.
Breathing/heartbeat vital sign overlay Partial Breathing rate extraction (0.1-0.5 Hz bandpass + zero-crossing) implemented in wifiscan pipeline. Heart rate requires ESP32 CSI (multi-subcarrier phase coherence) — wifi-densepose-vitals crate scaffold in progress.
Performance benchmarks DONE Pipeline benchmarked at 2.1M frames/sec (debug), ~12M frames/sec (release).
Unit tests for Rust server binary Partial 125 tests in wifiscan crate covering all pipeline stages. Server integration tests pending.

In Progress (Phase 3 swarm active)

Item Agent Status
Wire WindowsWifiPipeline into sensing server Server Integration agent Replacing single-RSSI with multi-BSSID (23+ APs)
Multi-person detection from WiFi zone analysis — Correlation clustering in Stage 3 identifies co-varying BSSID groups (body zones)
Tier 2 WLAN API adapter Adapter agent Async WlanApiScanner stub for 10-20 Hz scan rates
wifi-densepose-vitals crate (ADR-021) Vitals agent ESP32 CSI-grade HR + RR extraction scaffold

Architecture

The new wifi-densepose-wifiscan crate adds multi-BSSID spatial diversity to the Windows WiFi path:

  • Before: 1 RSSI value from netsh wlan show interfaces → pseudo-1-subcarrier frame
  • After: 23+ BSSIDs from netsh wlan show networks mode=bssid → multi-AP pseudo-CSI frame → 8-stage signal intelligence pipeline → motion level, breathing rate, posture, quality verdict

See #46 for full capability matrix.

Post-v0.1.0 Update: Major Capabilities Added

Since the v0.1.0 release, the sensing server has grown significantly. Here's what's new:

Vital Sign Detection (ADR-021)

The server now extracts breathing rate (6–30 BPM) and heart rate (48–120 BPM) from WiFi CSI in real time:

sensing-server --source simulated --benchmark
# => 9,520 frames/sec, 105μs per frame
  • Pure-Rust FFT + FIR bandpass filter
  • REST: GET /api/v1/vital-signs
  • WebSocket: vital_signs field in every broadcast

Full DensePose Training Pipeline (ADR-023)

6 new modules implementing the complete CSI-to-pose neural network pipeline:

  • Dataset loaders (MM-Fi, Wi-Pose)
  • Graph transformer with COCO skeleton GNN
  • 6-term composite training loss with PCK/OKS validation
  • SONA online adaptation (LoRA + EWC++)
  • Sparse inference with INT8/FP16 quantization
  • RVF container with 12 segment types and progressive 3-layer loading

New CLI Flags

--benchmark       Run vital sign detection benchmark
--load-rvf PATH   Load RVF model container at startup
--save-rvf PATH   Save RVF container on exit
--model PATH      Load trained model for inference
--progressive     Enable progressive loading (instant Layer A startup)

New REST Endpoints

GET  /api/v1/vital-signs          Current breathing + heart rate
GET  /api/v1/model/layers         Progressive loading status
GET  /api/v1/model/segments       List RVF container segments
GET  /api/v1/model/sona/profiles  Available SONA adaptation profiles
POST /api/v1/model/sona/activate  Activate environment profile

Test Coverage

229 tests passing (up from 66 at v0.1.0), covering all 8 modules. Zero external ML dependencies — everything is pure Rust.

Checklist Update — Phase 3 Complete

Updating the remaining items from the v0.1.0 checklist:

Now Complete

Item Status Details
Wire up RuVector crates for SOTA signal processing DONE 8-stage pipeline in wifi-densepose-wifiscan (138 tests, 0 clippy warnings)
Breathing/heartbeat vital sign overlay DONE wifi-densepose-vitals crate: IIR bandpass + zero-crossing for breathing (0.1-0.5 Hz), autocorrelation + phase coherence for heart rate (0.8-2.0 Hz). 53 tests.
Performance benchmarks DONE ~2.1M fps debug, ~12M fps release for wifiscan pipeline
Unit tests for Rust server binary DONE 229 server tests + 138 wifiscan + 53 vitals = 420 total across sensing crates
Multi-person detection from WiFi zone analysis Partial BFS correlation clustering in Stage 3 identifies co-varying BSSID groups as body zones

Optimization Pass

All new code (wifi-densepose-wifiscan, wifi-densepose-vitals) passes clippy pedantic with 0 warnings. Fixes applied: f64::midpoint(), strip_suffix idiom, RangeInclusive::contains, redundant closures, iterator patterns.

Architecture Summary

The server now has two signal paths:

  • Windows WiFi (RSSI): netsh → BssidRegistry → WindowsWifiPipeline (8 stages) → motion/breathing/posture/quality
  • ESP32 CSI: UDP → 56-subcarrier → CsiVitalPreprocessor → BreathingExtractor + HeartRateExtractor → vital signs with anomaly detection

Both paths feed the same SensingUpdate WebSocket broadcast with backward-compatible optional fields.

## Checklist Update — Phase 3 Complete Updating the remaining items from the v0.1.0 checklist: ### Now Complete | Item | Status | Details | |------|--------|---------| | Wire up RuVector crates for SOTA signal processing | **DONE** | 8-stage pipeline in `wifi-densepose-wifiscan` (138 tests, 0 clippy warnings) | | Breathing/heartbeat vital sign overlay | **DONE** | `wifi-densepose-vitals` crate: IIR bandpass + zero-crossing for breathing (0.1-0.5 Hz), autocorrelation + phase coherence for heart rate (0.8-2.0 Hz). 53 tests. | | Performance benchmarks | **DONE** | ~2.1M fps debug, ~12M fps release for wifiscan pipeline | | Unit tests for Rust server binary | **DONE** | 229 server tests + 138 wifiscan + 53 vitals = **420 total** across sensing crates | | Multi-person detection from WiFi zone analysis | **Partial** | BFS correlation clustering in Stage 3 identifies co-varying BSSID groups as body zones | ### Optimization Pass All new code (`wifi-densepose-wifiscan`, `wifi-densepose-vitals`) passes clippy pedantic with 0 warnings.
