LGTM!
You could also sign the SBOM as attestations: extract the SBOM and issue cosign attest over the file. I ended up updating my repo after opening the issue here 😅 (ref1, ref2). Downstream consumers might require the signature on the attestations before trusting the predicate (eg extractPayload from Kyverno).

Adds keyless Cosign signing for published container images. Enables full provenance and SBOM attestations in Buildx, then verifies both are present in GHCR.
Closes #225
