the sizing-intelligence layer moves the sizing layer from brand-level descriptions to individual normalized size rows. The database preserves the manufacturer's own ranges and records the sizing family so the future translator never assumes labels are standardized.

BRABAR is normalized as a method, not an alpha chart
BRABAR's published method rounds ribcage measurement to the nearest even band and maps bust-minus-band difference to cup size. For example, a one-inch difference maps to A, two inches to B and three inches to C. The database stores that formula separately instead of manufacturing a fake XS–XL translation.
Machine-readable data
The normalized source now lives at /data/size-intelligence.json. It records source status, sizing family, verification date, measurement ranges and notes about style exceptions.
