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.

Checksums and observation dates

For an APT source, signature verification authenticates the repository metadata chain and the Packages index containing this source-reported artifact digest. It does not certify package safety.

2.2-1+b1 / amd64Observed Sep 1, 2026 to Sep 1, 2026

Verification status: Metadata observed; artifact bytes were not independently fetched or hashed by this catalog import. The digest below is source-reported.

Source-reported sha256: 271206869a839e3b4ecd2d991f550ee6f5d9c15346543d0a16d5b553b9b0d19e

After downloading that exact artifact, compare its bytes with the source-reported expected digest:

printf '%s  %s\n' '271206869a839e3b4ecd2d991f550ee6f5d9c15346543d0a16d5b553b9b0d19e' 'alfa_2.2-1+b1_amd64.deb' | sha256sum --check --strict -

A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.

Sources and provenance

Field-source links above resolve here. Each source entry names the metadata publisher, trust tier, exact snapshot revision, signature result, and observation time; catalog-derived mappings are labeled separately.
