C.21:6.1 - Computer vision: direct comparison without a Bridge

Two ReproducibilityRate results concern the same benchmark population and ClaimScope. Both cite the same Characteristic and ratio Scale editions, the same DHCMethodRef.edition, compatible model and calibration rules, and matching 24-month population windows. The team compares the two rates directly under that basis. The source reports have different publication editions, but no distinct F.17 local senses are being related, so no F.9 relation is invented.

Formal benchmark approval and actual benchmark adoption are reported separately as FormalRecognitionStatus and PracticeAdoptionRate.
