How we ranked them

Coloprice Score is a 0–100 total of five axes: resilience (tier level weighted by the class of evidence, up to 35), compliance (independent audits, up to 20), transparency (how many of seven key fields are published, up to 20), scale (published MW on a log scale plus liquid cooling and AI readiness, up to 15) and maturity (status and age, up to 10). Every input is a field on the facility card, and every card cites its sources.

Nothing here is opinion or paid placement: an operator can only move up by publishing more data or citing more certificates. A dashed class means the operator disclosed too little for a class to be assigned honestly — the score is still computed.
