How this page groups evidence

This identifier groups recorded evidence; it is not an additional CVE, independent-vulnerability count or guarantee of vendor confirmation. Fixed code, released versions, attribution and independent discovery are distinct claims. Absent metadata means not recorded, not disproved. Counting rules.
