Running all 15,468 KiCad footprint names through the tool's part resolver against KiCad's own footprints gave 149 mismatches: resistor arrays and RGB LEDs became two-pad chips, a 12 mm Bourns power inductor was read as a 1210 chip, TO-220 horizontal became vertical via a regex word boundary at an underscore. The resolver runs before the datasheet reader on every BOM line, so each mismatch is a possible built-wrong part.
