import { HealthKit } from "@wellby/core";
class NeuralAnalyzer {
private let model = MLModel(name: "SleepEngine_v4")
func processBiometrics() {
let hrv = HealthStore.query(.heartRateVariability)
let readiness = model.prediction(input: hrv)
// Data stays local. No cloud upload.
Encryption.seal(readiness, key: .deviceOwner)
