The estate, as one operating picture.

An asset-light digital twin of a small estate: a twelve-storey block, its rooftop air handlers, its chiller yard, and 41 instrumented points. Click any asset for telemetry. Inject a fault and follow it down the lit riser to a work order that waits for a named human. Press Lattice to strip the picture away, or Play the fault to watch the whole loop with the camera driven for you. Synthetic data, method demonstration.

What this is, honestly. A demonstration twin built for this site. Every reading is synthetic and the fault script is written by me. The block comes from one AI-generated photograph, disclosed in Part 3 of the series; the roads, trees and ground are declared scenery and come from no photograph. The monitoring loop is the part I have delivered at estate scale. No client system and no client data. It is not a real building.
