Versions, suites, and repositories

Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
