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).
The Rust port lived two directories deep (rust-port/wifi-densepose-rs/)
without any sibling under rust-port/ that warranted the extra level.
Move the whole workspace up to v2/ to match v1/ (Python) at the same
depth and shorten every cd / build command across the repo.
git mv preserves history for all tracked files. 60 files updated for
path references (CI workflows, ADRs, docs, scripts, READMEs, internal
.claude-flow state). Two manual fixes for relative-cd paths in
CLAUDE.md and ADR-043 that became wrong after the depth change
(cd ../.. → cd ..).
Validated:
- cargo check --workspace --no-default-features → clean (after target/
nuke; the gitignored target/ was carried by the OS rename and had
hard-coded old paths in build scripts)
- cargo test --workspace --no-default-features → 1,539 passed, 0 failed,
8 ignored (same totals as pre-rename)
- ESP32-S3 on COM7 → still streaming live CSI (cb #40300, RSSI -64 dBm)
After-merge follow-up: contributors should `rm -rf v2/target` once and
let cargo regenerate from the new path.
