ruv 4d0521ca08 fix(hardware): aggregator tolerates sibling RuView UDP packet magics (#517)
The ESP32 firmware multiplexes several wire packet types onto the same
UDP port as ADR-018 raw CSI frames (magic 0xC5110001):

  0xC5110002  ADR-039 edge vitals (32 B)
  0xC5110003  ADR-069 feature vector
  0xC5110004  ADR-063 fused vitals
  0xC5110005  ADR-039 compressed CSI
  0xC5110006  ADR-081 feature state
  0xC5110007  ADR-095/#513 temporal classification

Esp32CsiParser only knew 0xC5110001, so the standalone `aggregator`
binary printed "parse error: Invalid magic: expected 0xc5110001, got
0xc5110002" for every vitals packet. No CSI data was lost — just noise.

Add the sibling-magic constants + ruview_sibling_packet_name(), classify
recognized siblings before the CSI-frame length gate, and return a new
ParseError::NonCsiPacket { magic, kind } instead of InvalidMagic. The
`aggregator` CLI now skips them quietly (logs "[skipped ADR-039 edge
vitals packet — not a CSI frame]" only with --verbose); the library-level
CsiAggregator already dropped them silently. New regression tests cover
all seven magics.

Closes #517

Hardware interface abstractions for WiFi CSI sensors (ESP32, Intel 5300, Atheros).

Overview

wifi-densepose-hardware provides platform-agnostic parsers for WiFi CSI data from multiple hardware sources. All parsing operates on byte buffers with no C FFI or hardware dependencies at compile time, making the crate fully portable and deterministic -- the same bytes in always produce the same parsed output.

Features

  • ESP32 binary parser -- Parses ADR-018 binary CSI frames streamed over UDP from ESP32 and ESP32-S3 devices.
  • UDP aggregator -- Receives and aggregates CSI frames from multiple ESP32 nodes (ADR-018 Layer 2). Provided as a standalone binary.
  • Bridge -- Converts hardware CsiFrame into the CsiData format expected by the detection pipeline (ADR-018 Layer 3).
  • No mock data -- Parsers either parse real bytes or return explicit ParseError values. There are no synthetic fallbacks.
  • Pure byte-buffer parsing -- No FFI to ESP-IDF or kernel modules. Safe to compile and test on any platform.

Feature flags

Flag Default Description
std yes Standard library support
esp32 no ESP32 serial CSI frame parsing
intel5300 no Intel 5300 CSI Tool log parsing
linux-wifi no Linux WiFi interface for commodity sensing

Quick Start

use wifi_densepose_hardware::{CsiFrame, Esp32CsiParser, ParseError};

// Parse ESP32 CSI data from raw UDP bytes
let raw_bytes: &[u8] = &[/* ADR-018 binary frame */];
match Esp32CsiParser::parse_frame(raw_bytes) {
    Ok((frame, consumed)) => {
        println!("Parsed {} subcarriers ({} bytes)",
                 frame.subcarrier_count(), consumed);
        let (amplitudes, phases) = frame.to_amplitude_phase();
        // Feed into detection pipeline...
    }
    Err(ParseError::InsufficientData { needed, got }) => {
        eprintln!("Need {} bytes, got {}", needed, got);
    }
    Err(e) => eprintln!("Parse error: {}", e),
}
