The one first-party client is the Velvt Assurance Runner — a single-file, zero-dependency Python 3 program distributed from the provider's own host as a version-pinned source release with a published SHA-256 and source commit. It is a CLI for one private Assurance engagement (see cli/), not a general SDK over the REST API, so no SDKs pointer is emitted. packages: - name: Velvt Assurance Runner (runner.py) language: python registry: vendor official: true url: https://www.velvt.ai/api/assurance/runner?version=0.4.6 metadata_url: https://www.velvt.ai/api/assurance/runner/metadata guide: https://www.velvt.ai/integrations/assurance/README.md config_example: https://www.velvt.ai/integrations/assurance/config.example.json version: 0.4.6 published: null published_note: >- The metadata endpoint declares version, protocol (velvt-assurance-runner/0.4), sha256 (a5aba940be634ff16332383e488baeee15f9b5390ea82ea8e5010bcb607e4763), sourceCommit (0c6673ad62ed83510d669eddc5788091276ade7e) and distribution VERSION_PINNED_SOURCE_RELEASE, but no release date.
