…erenced manifests build-push-action defaults attach provenance/SBOM attestations, making each tag an OCI index with untagged child manifests. The weekly untagged-image cleanup (min-versions-to-keep: 0) deleted those children, breaking every tag (404 on pull). Set provenance:false/sbom:false for a plain single-platform manifest, and give prune-untagged a min-versions-to-keep buffer plus a hazard warning.

manifest unknown/ 404) — the publishworkflow built with
docker/build-push-actiondefaults, which attach provenance/SBOMattestations and turn each pushed tag into an OCI image index whose per-platform and
attestation manifests are untagged. The weekly "Cleanup Container Images" job deleted
untagged versions with
min-versions-to-keep: 0, removing those child manifests and leavingevery tag (
:latest,:v0.1.1, …) pointing at a missing manifest. The build now pushes aplain single-platform manifest (
provenance: false,sbom: false), and the cleanup keeps abuffer (
min-versions-to-keep: 5) with a warning that untagged-deletion is unsafe forindexed/attested images. Pulling
:latestworks again after the next publish.
