Admission by reading (§3.4): D where a deposit names the entity and says something of it; O-class where a sentence applies an archive category (the Provenance Erasure Rate, parametric claims, citation against matching, the composition layer against the training layer) to tracing outputs to training data or to training-data provenance as a class; a bare list of tools, a citation-list entry or a reference line is not a claim.",
