The registry cache mode imports from the output image reference, which does not exist for a new revision, and the inline export covers only final-stage layers. A non-empty cache-ref imports from and exports to one dedicated reference with mode max, which caches every build stage. An empty cache-ref keeps the current behavior, so existing consumers do not change.

Binjovi will pass cache-ref for its self-builds in a follow-up; the trust reasoning is documented there.
