Six biometric sensors stream continuous data to UNA: heart rate variability from Apple Watch, sleep architecture from Oura Ring, continuous glucose from Dexcom G7, blood oxygen, skin temperature, and stress markers. She doesn't just collect this data — she correlates it, detects anomalies, and adjusts her behavior to match my cognitive and physical state. When my HRV drops, she knows to simplify. When my glucose spikes, she flags it before I notice.
