notes: 'Developer/operator "Sabey Data Centers" has no operators.yml entry — needs one before
  the developer/operator field can be set. Status announced: signal reports "proposed (land
  option/purchase agreement)". Capacity: NorthWestern Energy approved 50 MW starting 2026,
  expandable to 250 MW (capacity_mw reflects the approved 50 MW; 250 MW is the expansion ceiling).
  land_acres 600 from "600+ acres". building_sqft 1,000,000 derived from "two 500,000 sq ft
  buildings" (buildings: 2). Single source (Bozeman Daily Chronicle) → medium confidence.
  Distinct campus from Atlas Power Butte despite shared locality.'
