All newly added affected entries use {"introduced": "0"} with different fixed versions. With semver ordering, the first range introduced: 0 → fixed: 10.2.1 still marks versions like 9.0.6, 8.0.5, etc. as affected (since they’re < 10.2.1), so the backported fix releases will be incorrectly reported as vulnerable. Model backports as disjoint ranges by setting introduced to the start of each maintained major line (eg 10.0.0→10.2.1, 9.0.0→9.0.6, …) and keep only the oldest range as 0→3.1.3 (or whichever earliest fixed version applies).
