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.

Version	Release	Architecture	Repository	Package size	Installed size	Publisher repository artifact
0.11.0+ds-4+b1	bookworm / main	amd64	Debian 12 · main · amd64	254 KiB	1.7 MiB	pool/main/n/numcodecs/python3-numcodecs_0.11.0+ds-4+b1_amd64.deb

Field source: Debian 12 (Bookworm) main amd64 revision bookworm-main-amd64:9e0b5aabb2465b3d2e7a7fe27f9913846277833f7a2826e7767acccff5b588c5

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.

0.11.0+ds-4+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: ab412b39b562e4e0741d2c80ad7f00d951b0d804d4cf21dabf4f92a2e8002c4c

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

printf '%s  %s\n' 'ab412b39b562e4e0741d2c80ad7f00d951b0d804d4cf21dabf4f92a2e8002c4c' 'python3-numcodecs_0.11.0+ds-4+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.

Catalog record completeness

The completeness score measures metadata coverage, not software quality, security, compatibility, or suitability.
