A frontier proposal with a validation plan, not an implemented detector.
Intended capability
Evaluate the sensing evidence for “Cough & Nocturnal Event Counter” in a consented, ground-truthed study. This is not a medical device, clinical monitor, diagnosis, or emergency alert.
This describes the intended outcome. Readiness is research concept, evidence is class C, 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 Healthcare scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
A cough is a violent, sub-second whole-torso jerk: a broadband 4-40Hz Doppler transient with a characteristic sharp onset, distinct from turn-over events (slower, lower band) and breathing (narrowband 0.1-0.5Hz).
02 Shared processing path
Edge Doppler-band summary at night -> burst detector (band-energy spike with fast rise, sub-second support) -> burst classifier cough vs reposition via band-ratio shape -> per-night counts joined with the breathing estimator's rate trend.
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
Own-hardware overnight studies with consented participants and an audio reference for labeling only; report per-night count agreement and the reposition/cough confusion rate. No public RF cough dataset exists — frontier build.
04 Commercial hypothesis
For the household: 'A worsening-cough trend without a microphone in the bedroom.'
