89074 / Henderson: freeze the geography
89074 is the inquiry's geographic starting point. The underground architecture question must be attached to a specific site before it becomes a facility claim. A postal area, a regional data-center corridor and an individual parcel are different units of evidence.
Investigative question: Which exact parcel, permit, utility connection or company record supports each proposed facility?
Evidence test and competing explanation
Test: Record the address, parcel identifier, issuing authority, record date, excavation scope and operator. Compare the record with the proposed location. No facility inside 89074 is authenticated by this integration.
Counter-reading: Ordinary utility corridors, commercial construction and regional infrastructure can account for visible activity without a hidden computing installation.
