A frontier proposal with a validation plan, not an implemented detector.
Intended capability
Evaluate the sensing evidence for “Resting Heart-Rate Trend (Bedside, Frontier)” 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
Cardiac ballistic motion moves the chest surface sub-mm at 0.8-2Hz; recoverable from CSI phase when the subject is motionless and the link is Fresnel-favorable. The night-shift-vitals entry already flags this band as 'recoverable... frontier'; this entry gives that flag its own honest home.
02 Shared processing path
Sleep-still episode gating -> heart-rate estimator (0.8-2Hz autocorrelation with inter-subcarrier phase coherence) at >=4Hz effective sampling -> nightly RHR distribution; output withheld entirely until the deployment passes its ECG-referenced validation gate.
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 vs a consented ECG reference; report per-night RHR MAE and the fraction of nights with sufficient still time. Upstream estimator explicitly unvalidated for this claim — that is the point of the gate.
04 Commercial hypothesis
For the wellness user: 'A resting heart-rate trend with no strap — shown only after your setup has proven itself against a reference.'
