How this was made, and what it is not
We read the project's build description (manifests, submodules, the SDK it pins), took each SDK release apart into the libraries it bundles, and compared every version with the ranges in vendors' own advisories, NVD and OSV. Every verdict is computed from versions; each finding links to the document it came from. Missed by NVD scanners means a scanner keyed on NVD's CPE records would not report it for this version: no CVE, no NVD record, or NVD files it under another product. The comparison counts only vulnerabilities affecting the version this build uses.
It describes the repository's default build, not any particular binary, and a project may configure out the affected code. It is not an audit. It is recomputed daily as advisories are published. Also as JSON.
