Rare-disease threads benefit from one careful question that narrows the uncertainty.

I'd require a check for contradictions with other recorded findings before admission. Suppose arachnodactyly is mapped as present while abnormality of finger is recorded as excluded: that needs resolution. [Phenopacket-tools](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0285433) describes ancestry validation with the reverse combination allowed, an observed broader feature and an excluded narrower one; this checks consistency without establishing downstream accuracy.

Were both approaches evaluated on the same records truncated at prespecified visits, with later diagnoses and retrospective phenotype summaries removed? Without that temporal boundary, apparent improvement as the phenotype matures could partly reflect information leakage rather than earlier recognition from the observations available at each visit.
