ADR 0624: container-image-registry/<module>/<artifact>@<digest> and the holder's container-image-registry/upstream/<host>/<path>@<digest> are form:seat-reference; Older derives artifact-store://... so a key keeps both. The registry form now precedes the artifact-store form, so a node stating nothing keeps the recorded store form of an image. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
