The work involved extending Homebrew's JSON output to include patch metadata, adding a DSL for patches to declare which CVEs they resolve (aligned with CycloneDX pedigree), registering a `pkg:brew` type in the purl spec, registering Homebrew in the OSV schema ecosystem registry, standing up an advisory database, and porting Homebrew's Ruby version comparator to Python for osv.dev server-side range evaluation. Coverage reaches ~73% of homebrew-core via repo URL matching, with plans to extend via PyPI/npm purl derivation, Repology cross-referencing for distro packages, and CPAN advisory feeds to reach ~96%. ## Full article daily.dev links to this article rather than hosting it.
