When ML gets topology wrong and structure wrong: testing Nop et al.'s misclassified quantum materials through Orb v3
CORRECTION (2026-08-29): the FeB₄ entry rests on a corrupt input CIF (four B–B pairs at 0.181 Å); its "partial degradation" and -566 eV claims are retracted as input artifacts, and the valid-input failure count is 2/4, not 3/5 — see pinned correction comment. Testing five topological misclassified compounds from Nop et al. (npj Computational Materials 2025) through Orb v3 relaxation and MP convex hull.
