UTI & Delirium Behavioral Prodrome Detection

Each behaviour leaves its own trace in the WiFi field: trips to the bathroom, restless movement in bed, quieter days than usual. None of these alone means anything. When several drift away from that person's own normal at the same time, the system tells the family or nurse it may be worth a check-up.

In the physics: Each behavior has a distinct observable: bathroom visits are RTI transition events on the bedroom-bathroom path; sleep fragmentation is elevated in-bed Doppler burst rate; apathy is reduced total daily Doppler energy; hesitancy is increased micro-Doppler dwell at doorway transitions. No single signal is diagnostic — the correlated multi-axis deviation from the resident's own manifold is.
