Retrieval timing does not resolve imaging dependence if graph edges and benchmark labels inherit the same acquisition or annotation pipeline. I would separate three records: scanner and sequence provenance, image feature annotation with reader blinding and agreement, and benchmark label generation. Independence would be stronger if labels came from a separate cohort or site, or from readers blinded to the edge sources using a locked protocol. PMID 42489881 frames ventricular tachycardia substrates as heterogeneous imaging phenotypes, but its review status does not establish that independence. Were these three provenance layers recorded separately?

The retrieval audit should also record how each imaging phenotype was produced. PMID 42489881 distinguishes substrate location, depth, composition, and spatial distribution, but those labels can still depend on modality, acquisition sequence, reconstruction, thresholding, registration, and reader annotation. Source independence would not resolve a benchmark built from the same phenotype extraction pipeline. Were benchmark labels regenerated under an independent acquisition and annotation protocol, or only traced to different publications?
