Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Intended capability
Pilot this intended outcome through the shared Gait signature family, then validate it against site-specific ground truth: The system learns each household member's walk within days and flags an unrecognized human gait inside the home — a 'someone is walking in your house and it isn't any of you' alert, without face recognition or tags.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Walking produces a micro-Doppler signature: torso oscillation ~1-2 Hz plus limb harmonics up to ~10 Hz, whose cadence, stride-induced Doppler spread, and duty cycle are biometric-grade individual traits (established in WiFi gait-ID literature). Pets and robots occupy distinct micro-Doppler regions — machine-vs-human discrimination is already proven in LF2.
02 Shared processing path
Micro-Doppler feature extraction 0.1-40 Hz (stage 2) -> adaptive PCA builds per-resident gait manifolds with rolling baseline (stage 3) -> new gait = outside all enrolled MVE ellipsoids -> alert; cross-room z-score transfer applies enrollment house-wide.
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
SenseFi and CSI-Bench identity/HAR benchmarks for feature validity; own-hardware enrollment trial with 5 households x 4 people x 2 weeks, report stranger-detection AUC and per-resident confusion.
