Mass Casualty Assessment Tool for WiFi-based disaster survivor detection and localization.

## Overview

`wifi-densepose-mat` uses WiFi Channel State Information (CSI) to detect and locate survivors
trapped in rubble, debris, or collapsed structures. The crate follows Domain-Driven Design (DDD)
with event sourcing, organized into three bounded contexts -- detection, localization, and
alerting -- plus a machine learning layer for debris penetration modeling and vital signs
classification.

Use cases include earthquake search and rescue, building collapse response, avalanche victim
location, flood rescue operations, and mine collapse detection.

## Features

- **Vital signs detection** -- Breathing patterns, heartbeat signatures, and movement
  classification with ensemble classifier combining all three modalities.
- **Survivor localization** -- 3D position estimation through debris via triangulation, depth
  estimation, and position fusion.
- **Triage classification** -- Automatic START protocol-compatible triage with priority-based
  alert generation and dispatch.
- **Event sourcing** -- All state changes emitted as domain events (`DetectionEvent`,
  `AlertEvent`, `ZoneEvent`) stored in a pluggable `EventStore`.
- **ML debris model** -- Debris material classification, signal attenuation prediction, and
  uncertainty-aware vital signs classification.
- **REST + WebSocket API** -- `axum`-based HTTP API for real-time monitoring dashboards.
- **ruvector integration** -- `ruvector-solver` for triangulation math, `ruvector-temporal-tensor`
  for compressed CSI buffering.

## Quick Start

```rust
use wifi_densepose_mat::{
    DisasterResponse, DisasterConfig, DisasterType,
    ScanZone, ZoneBounds,
};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let config = DisasterConfig::builder()
        .disaster_type(DisasterType::Earthquake)
        .sensitivity(0.8)
        .build();

    let mut response = DisasterResponse::new(config);

    // Define scan zone
    let zone = ScanZone::new(
        "Building A - North Wing",
        ZoneBounds::rectangle(0.0, 0.0, 50.0, 30.0),
    );
    response.add_zone(zone)?;

    // Start scanning
    response.start_scanning().await?;

    Ok(())
}
```
