…ds are both present When both 'cve' and 'vulnerability_ids' were present in generic JSON import, .append() was used instead of .extend(), causing a nested list: ['CVE-2020-36234', ['GHSA-5mrr-rgp6-x4gr', 'OSV-2021-1234']] instead of ['CVE-2020-36234', 'GHSA-5mrr-rgp6-x4gr', 'OSV-2021-1234'] Without 'cve', vulnerability_ids worked correctly via direct assignment. The bug only manifested when both fields were present simultaneously. Added test to verify flat list behavior. Updated documentation with vulnerability_ids example.
