Automated registry-metadata scan; not a code audit. Findings come from npm metadata published by the package owner and from public security advisories (OSV/GHSA) — not from our own assessment of the code.
Grade scanned 2026-09-04 · package count resolved 2026-08-18. A package fixed after that date will still show its earlier grade here.
