⭐ App Repo: 65 WASM edge modules, ADR-042 coherent sensing protocol, vendor integration, docs overhaul

[ruvnet]

Overview

This issue tracks the complete vendor integration and edge intelligence expansion for WiFi-DensePose. The branch feat/complete-vendor-and-edge-intel delivers 5 commits across 1,883 files, introducing a new coherent RF sensing protocol (CHCI), 65 WASM edge modules that run directly on ESP32 hardware, vendor library integration, and comprehensive documentation updates.

In plain terms: WiFi-DensePose already detects people through walls using WiFi signals. This release makes those detections smarter by running 65 tiny analysis programs directly on the $8 ESP32 chip -- no cloud needed, instant response. It also introduces a next-generation sensing protocol (CHCI) that controls both transmitter and receiver for dramatically better accuracy.

What was delivered

1. ADR-042 -- Coherent Human Channel Imaging (CHCI)

A new architecture decision record for a purpose-built coherent RF sensing protocol. Unlike passive CSI eavesdropping (which relies on whatever WiFi traffic happens to be in the air), CHCI controls both transmitter and receiver with a shared clock.

What CHCI enables:

• Phase-locked dual-radio architecture: Two ESP32-S3 radios sharing a single SI5351A PLL synthesizer, achieving < 0.1 radian phase noise across all antennas
• Multi-band coherent fusion: Simultaneous sounding across 2.4, 5, and 6 GHz bands -- 3x bandwidth without spectrum cost
• Time-coded micro-bursts: 4-20 microsecond OFDM pulses at 1-5 kHz cadence -- 100x less airtime than standard WiFi beacons
• Cognitive waveform adaptation: 6 sensing modes (IDLE / ALERT / ACTIVE / VITAL / GESTURE / SLEEP) that automatically adjust based on what the system detects
• Coherent diffraction tomography: Reconstructs body surface geometry from phase perturbations, not just volumetric shadows
• Sub-millimeter displacement: 0.031 mm resolution with 8-antenna coherent averaging

DDD domain model: 6 bounded contexts (Waveform Generation, Clock Synchronization, Coherent Signal Processing, Cognitive Waveform, Displacement Measurement, Regulatory Compliance) with full Rust struct/enum definitions and domain events.
