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 Occupancy estimate family, then validate it against site-specific ground truth: Automatic headcount verification for confined-space entries and live electrical rooms: system knows how many bodies are inside a permit boundary at all times, through the wall, and reconciles against the permit. A worker who goes still never decrements 'souls inside' — an mmWave radar aimed through the entry hatch holds their presence until an exit is actually seen.
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.

Bundled recording
A related Industrial scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Each human body inside the space perturbs multipath with breathing (0.1-0.5Hz) and motion Doppler; occupancy count correlates with aggregate perturbation energy and mode count. Through-wall sensing (LOS/NLOS discrimination proven) lets nodes sit outside the hazardous boundary.
02 Shared processing path
Through-wall CSI: Doppler + breathing features (stage 2) -> occupancy count regression (proven r=0.9) -> RTI localization to confirm bodies are inside vs outside the boundary (stage 4) -> hatch-aimed radar static hold carries stationary presence, so the count can only fall on a matching exit event -> CUSUM on count-vs-permit mismatch duration (stage 6) to trigger alarms only on sustained discrepancy.
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
WiMANS multi-person counting and OPERAnet occupancy for the count model; ESP32-wall for the through-boundary configuration; own-hardware drill in a real vessel/electrical room during a planned entry.
04 Commercial hypothesis
A live 'souls inside' counter for every confined-space permit — sold to the permit-to-work coordinator as automated attendant backup.
