Both triage paths in the Mass Casualty Assessment tool classified a survivor as Deceased (Black) on "no breathing + no movement" while completely ignoring the heartbeat signal: - domain `TriageCalculator::calculate` → `combine_assessments(Absent, None)` returned Deceased. That branch is in fact only reachable *because* a heartbeat makes `has_vitals()` true (breathing+movement absent alone → Unknown) — so every "Deceased" was a live person with a pulse. - detection `EnsembleClassifier::determine_triage` (the path used by `classify()`) returned Deceased on `!has_breathing && !has_movement`, also ignoring `reading.heartbeat`. A survivor with a detectable pulse but no sensed breathing/movement is in respiratory arrest — the most time-critical *savable* state. Reporting them Deceased would deprioritize a rescuable person. WiFi-CSI also cannot confirm death (no airway-repositioning step), so a pulse must override. Fix: in both paths, if the result would be Deceased but a heartbeat is present, return Immediate. Total absence of breathing, movement AND heartbeat is unchanged (domain → Unknown, ensemble → Deceased). 2 safety regression tests added. Full MAT suite: 168 + 6 + 3 passed, 0 failed (existing test_no_vitals_is_deceased still green — no heartbeat → Deceased). |

wifi-densepose-mat
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 pluggableEventStore. - 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-solverfor triangulation math,ruvector-temporal-tensorfor compressed CSI buffering.

Quick Start
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(())
}
