title: "What ATI can and cannot see of the U.S. project universe: registered sources by family with project counts and known capex, the state x sector coverage matrix, archetypes observed but NOT modeled with the blocker reason for each, per-jurisdiction disclosed gaps, the latest capture-recall benchmark and the current top blind spots. Every denominator is what ATI has observed from public sources, never total U.S. investment. Costs 30 credits per call (research); the response carries X-ATI-Credits-Charged and X-ATI-Credits-Remaining."
