The evidence is proven or strong, but this capability still needs a capability-specific ESP32 or Rust runtime adapter.
Intended capability
Validate this target only after a capability-specific adapter and ground-truth study exist: Each door and window becomes a monitored RF structure: opening, prying, propping ajar, or removing a pane is detected from the multipath geometry itself — no contact sensors, no batteries on the frame, and it catches the state (left ajar) not just the event.
This describes the intended outcome. Readiness is needs edge adapter, 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
A door or window is a large planar reflector that defines specific multipath echoes. Rotating a door 10 degrees or lifting a sash by 5 cm moves reflection points tens of cm, shifting individual path delays by ~1 ns and re-routing which paths exist at all. Glass and wood panels also change transmission through that aperture. This is a static geometric change — invisible to Doppler-only systems but directly visible in the CIR delay set.
02 Shared processing path
CIR sparse recovery (stage 1) resolves per-aperture path delays -> per-compartment Kalman tracks each entry point's delay signature (stage 6) -> instant anomaly for fast tamper via MVE (stage 3), CUSUM for 'left ajar for 3 hours' states.
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
CSI-Bench/OPERAnet door open-close activities as a sanity base, then own-hardware: 20 sessions of open/pry/ajar/remove-screen on 4 window types, measure delay-set distance vs baseline and false-alarm rate over a 2-week undisturbed control period (119-day drift control shows the baseline holds).
04 Commercial hypothesis
"Every window is a sensor and none of them need batteries." Replaces dozens of contact sensors for alarm installers and vacation-rental owners.
