notes: >
  Two-building campus, 446,000 sq ft total; 40 MW is stated as initial IT
  capacity, so treated as IT-load basis. Groundbreaking Sept 13, 2024;
  operator states opening "early 2026" — too imprecise to normalize to a
  date, recorded here rather than in operational_date. Operator is CyrusOne,
  which has no operators.yml entry — operator field omitted; needs an
  operators.yml entry before it can be set. Single primary source
  (CyrusOne press release), hence medium aggregate confidence.
