Unclear The finding doesn't say why the release-matching requirement was removed or what effect this has in practice.

What

A check for whether the model catalog is from Anthropic itself ("first party") used to also require that the catalog's release matched a specific expected release. That release-matching requirement was removed, so now only the first-party flag is checked.

Why

This loosens the readiness check for the first-party model catalog, meaning it can now be considered ready without also matching a specific release, though the finding doesn't say what problem this fixes.
