ruv b4b626fad3 fix(calibration): close all four ADR-152 behavioral findings pre-hardware-session
The full-loop integration test surfaced three findings; fixing the third
exposed a fourth. All four are fixed and regression-guarded:

1. z-band squeeze (enrollment.rs) — anchor motion is now measured from
   frame-to-frame deltas of the deviation series (|Δz| > Z_DELTA_MOTION
   0.5 ∨ |Δφ| > π/6), not from the absolute motion_flagged, which fires
   at amplitude_z_median > 2.0 vs the EMPTY baseline and so conflated
   presence strength with motion. A strongly-reflecting still person
   (z = 3.0 — every frame flagged by the old heuristic) now enrolls.
   The old unit tests mocked (z=3.0, motion=false), a combination the
   real deviation() can never emit — which is exactly how the squeeze
   hid; tests now derive the flag from z the way the producer does.

2. variance-only presence (specialist.rs) — PresenceSpecialist gains a
   mean-shift channel: present when variance > threshold OR
   |mean − empty_mean| > mean_dist_threshold (trained at half the
   empty→occupied mean distance, None when the means don't separate).
   Detects the motionless person whose body raises the scalar mean but
   not its variance. Old persisted banks deserialize with the channel
   inert (serde default None) — variance-only behavior preserved,
   proven by a fixture test against pre-change JSON.

3. ungated hz embedding (extract.rs) — Features::embedding() zeroes
   breathing_hz/heart_hz below EMBED_MIN_SCORE (0.25), keeping the
   random in-band peaks of noise windows out of the posture/anomaly
   prototype space. Raw fields stay ungated (specialists have their
   own stricter gates).

4. heart-band lag-floor leakage (extract.rs, found while fixing 3) —
   a pure 0.30 Hz breathing signal scored 0.67 in the heart band at
   3.33 Hz: out-of-band rhythm leaks as a monotonic slope whose max
   sits at the band's lag floor, so score gating alone cannot stop it.
   autocorr_dominant now requires the winning lag to be an interior
   local maximum; band-edge "peaks" are rejected, true in-band peaks
   (interior by definition) are preserved.

full_loop.rs strengthened to drive the fixes end-to-end: the StandStill
anchor is now a z=3.0 strong reflector (unenrollable pre-fix), and a new
motionless-person runtime case proves mean-channel detection at empty-
level variance.

Validation: 41 calibration unit + 1 full-loop integration + 23 CLI tests
green; cargo test --workspace --no-default-features exit 0.

WiFi-DensePose Rust Crates

License: MIT OR Apache-2.0 Rust 1.85+ Workspace RuVector v2.0.4 Tests

See through walls with WiFi. No cameras. No wearables. Just radio waves.

A modular Rust workspace for WiFi-based human pose estimation, vital sign monitoring, and disaster response using Channel State Information (CSI). Built on RuVector graph algorithms and the WiFi-DensePose research platform by rUv.
