📄 Description

Overview

Released self-hosted images now carry signed SPDX SBOM attestations, so the placeholder note in the image mirroring guide ("SBOM attestations are not yet attached…") is out of date.

This replaces that note with a Verifying SBOM attestations section that documents how to:

  • Resolve the per-architecture child digests for a tag (attestations attach to the child digests, not the multi-arch tag — verifying a bare tag reports no matching attestations).
  • Verify each attestation with cosign verify-attestation --type spdxjson against the stable-branch release workflow identity.
  • Decode the verified predicate to the SPDX 2.3 document.

Follows on from #4196 (cosign image-signature verification).
