Commissioning Copilot: Poke-and-Learn Building Twin

The system runs the building through its motions — dampers, doors, blinds, elevators — one at a time, watching how each action changes the WiFi field. Because each change happens on command, its signature is learned cleanly. The result is a building that can verify its own equipment states for the rest of its life.

In the physics: Every actuator changes either geometry (doors, blinds: multipath tap constellation), materials (moisture, fill: eps_r field) or vibration (fans, pumps: micro-Doppler lines). Controlled perturbation with known labels isolates each actuator's signature dimension from ambient variance — the building teaches the sensor its own vocabulary.
