Core Entities - Patient (demographics, consents, EHR link) - Enrollment (study/site, clinician, status) - CheckIn (weekly micro responses, scores) - KCCQResponse (licensed responses, subscales, total) - SpeechFeature (on‑device features, no raw audio by default) - WearableMetric (steps, HR/HRV, sleep, weight) - EnvironmentReading (noise dB, lux, AQI, weather hash) - QoLScore (five domains + composite, versioned) - Alert (rule id, evidence, status, acknowledgement) - AuditLog (actor, action, resource, before/after, timestamp) - FHIRLink (resource ids, provenance)
