Provenance
Image provenance tracking
Provenance provides cryptographically verifiable tracking of each image's origin from source code, through the build environment, to publication in the registry. The system generates attestations compliant with SLSA Level 3, documenting builder identity, source repository, commit hash, and build parameters. Attestations are signed by Sigstore and stored as OCI artifacts alongside the image.
