Now I need to check for specific quality issues: (1) inconsistent formats in key text fields like model names, organizations, dates; (2) mixed units or scale issues in numeric fields; (3) outliers beyond the min/max I already have. Let me examine the actual values in critical dimension columns to spot formatting inconsistencies, and check for unit mixing in the compute/cost fields.",
