Select a source below for its declared licence, revision, evidence and unresolved checks. An engine can offer several sources or variants; these records are not an installed-file manifest.

  • Evidence and configured runtime revisions differ.

Registry 2026-10-09.draft1; evidence checked 2026-10-03. This is disclosure-only foundation work. It does not mean released apps enforce review before every download, and no real model workflow is verified ready by this snapshot. A local acknowledgement does not grant rights or complete a provider's own agreement or gated-access process.
