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 Fall event family, then validate it against site-specific ground truth: The security system doubles as a life-safety monitor when armed-stay: the WiFi mesh detects falls and exit events, and a small mmWave radar aimed where a person should be — the bed, the reading chair — holds their breathing presence, so 'no motion AND no breathing' escalates honestly rather than guessing. One system, two subscriptions.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class A, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording
A related Home scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Falls produce a high-Doppler transient followed by sustained floor-level stillness; respiration modulates chest-wall reflections at 0.1-0.5 Hz and heartbeat proxy at 0.8-2 Hz — periodic path-length changes of millimeters that are resolvable in CSI phase. Fall AUC 0.8 and presence are already proven in LF2.
02 Shared processing path
Doppler transient + micro-Doppler stillness signature (stage 2) -> fall classifier on anomaly manifold (stage 3) -> LD2410 static-target energy in the aimed cone as the breathing-presence channel, tracked via compartment Kalman (stage 6), with CUSUM escalation when static energy disappears without an exit event from RTI (stage 4).
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
OPERAnet (breathing, activities) and CSI-Bench fall tasks; own 30-day pilot in 5 homes with wearable ground truth for breathing-rate agreement.
04 Commercial hypothesis
"The alarm that also notices Grandma hasn't moved since 2 pm." Upsell ARPU for alarm monitoring companies serving aging-in-place households; the breathing watch is a plus-tier mmWave radar add-on aimed at the bed or chair where stillness matters most.
