The files are 100-400MB and unreadable; we resolve each shoppable CPT/HCPCS code across every code column, read its discounted_cash, flag estimates and omit honestly. The moat is the normalization — the clean cross-hospital matrix a benefits team, patient-cost estimator or price-shopping startup would otherwise rebuild per hospital.",
