notes: >-
  Cancelled record (negative outcome, not omitted): CoreWeave terminated its
  250 MW anchor lease and the Poolside–CoreWeave partnership ended, pausing the
  project. Developer Poolside and anchor tenant CoreWeave both need
  operators.yml entries (developer field omitted). Planned 2 GW behind-the-meter
  (eight 250 MW phases) on 568 acres at Longfellow Ranch; capacity/land figures
  are the pre-cancellation plan.
