Complete 7-component sensor fusion pipeline (all working)
1. ADR-018 binary parser — decodes ESP32 CSI UDP frames, extracts I/Q subcarriers 2. WiFlow pose — 17 COCO keypoints from CSI (186K param model loaded) 3. Camera depth — MiDaS on CUDA + luminance fallback 4. Sensor fusion — camera depth + CSI occupancy grid + skeleton overlay 5. RF tomography — ISTA-inspired backprojection from per-node RSSI 6. Vital signs — breathing rate from CSI phase analysis 7. Motion-adaptive — skip expensive depth when CSI shows no motion Live results: 510 CSI frames/session, 17 keypoints, 26% motion, 40 BPM breathing. Both ESP32 nodes provisioned to send CSI to 192.168.1.123:3333. Magic number fix: supports both 0xC5110001 (v1) and 0xC5110006 (v6) frames. Co-Authored-By: claude-flow <ruv@ruv.net>

//! Receives raw UDP frames from ESP32 nodes, extracts I/Q subcarrier data,
|

//! runs the WiFlow pose model, detects motion, estimates vitals, and produces

//! 3D occupancy + skeleton for fusion with camera depth.
