Generated from the provider-published UpstreamDrift artifact upstreamdrift-companion-27b6eeadbbd970bebb8926a3c83aeaea1f6ee4da (manifest SHA-256 a1c9a799ecceb4e81f28c50755fb50ad28f390ed8db335b64ecb89028f910b06; attestation: verified: gh attestation verify (actions/attest-build-provenance); installed 2026-09-03). The provider marks this catalog draft: Engine capability claims require qualification evidence. Documentation and screenshot inventories require their governed provider slices. See the freshness dashboard.
