  "abstract": "GNoME's stability labels rest on a Materials Project-compatible GGA/GGA+U workflow. Its authors report that 84% of discovered binaries and ternaries retain a negative decomposition energy under r2SCAN and 86.8% of tested quaternaries remain stable on the r2SCAN hull. We resolve that aggregate by chemistry over the 139,541 GNoME materials released with r2SCAN recomputations, a subset the dataset authors selected rather than sampled, using cluster bootstrap intervals over 8,429 structural-prototype proxy clusters. The aggregate conceals a 26.7-point spread at fixed element count, from 4.0% [3.3, 4.7] for plain quaternary intermetallics (no lanthanide, no 3d metal) to 30.7% [27.7, 33.8] for lanthanide-free 3d-containing quaternary oxides, a pair identified post hoc against a prospectively fixed threshold. Under our reading of the release's \"All\" reference set the two cells sit at 14.5% and 37.4%, preserving a 22.9-point spread. Presence of a Materials Project Hubbard-U-list element is strongly associated with disagreement, conditional on the other covariates, in a model over all 139,541 materials (cluster-robust odds ratio 3.45 [3.13, 3.80]). Neither selective U application nor hull proximity explains the association away: disagreement stays elevated outside the U-treated regime, and a natural cubic spline in the continuous PBE decomposition energy moves the odds ratio in the 117,018-material model only from 3.53 to 3.43 [3.07, 3.83]. For allocating a verification budget, composition supplements hull proximity rather than replacing it: over held-out cluster splits at a 20% budget, the two together surface 45.8% of disagreements against 40.4% for hull distance alone. An exploratory comparison against previously catalogued materials changes direction between populations. We measure disagreement between two workflows, not accuracy.",
