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 Presence family, then validate it against site-specific ground truth: Detects 'occupied, motionless, too long' in single-occupancy rooms where cameras are forbidden and CSI coverage is thinnest — restrooms, phone booths, lactation and first-aid rooms. The syncope case with no fall burst: someone goes in, goes still, and nobody checks.
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.
Solution blueprint
See the environment before installing it.
This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording
A related Buildings scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
In a one-person compartment the LD2410C's single-composite-target limit becomes a feature: static micro-motion (breathing) holds the occupant indefinitely at 2-4 m, ms-class detect with configurable absence hold. A dwell timer on 'present and static past policy threshold' is honest part-spec physics — no rate, fall, or identity claim; entry/exit context comes from the corridor CSI mesh.
02 Shared processing path
CSI corridor entry event -> LD2410 in-room presence confirm -> stillness clock (static-only energy, no moving bursts) -> policy-threshold welfare page with occupied-duration evidence
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
Per-room pilot: occupied-still vs empty discrimination across full HVAC duty cycles; false-hold audit against hand dryers, auto-flush fixtures and door swings; staged still-occupant drills timing page latency at policy thresholds.
04 Commercial hypothesis
'Nobody lies unnoticed behind a locked door' — for facilities and EHS managers with welfare duties over single-occupancy spaces.
