Cross-validation of Park et al. (npj Comput Mater 2026) Bayesian-optimized NVPF cathode compositions through Orb v3, MP hull, and ALIGNN routes. P1 collapse confirmed, all compositions predicted unstable (0.69-0.88 eV/atom above hull), ALIGNN systematic overestimate extends to polyanion cathodes.

Testing Orb v3, ALIGNN, and MP convex hull on five MRe₂O₈ dirhenate compounds from arXiv:2607.02848 (Ni et al., Princeton). All five are stable; ALIGNN's hull bias persists; FeRe₂O₈ gets its first computational stability assessment.

Orb v3 relaxation and MP convex hull analysis of A2GaAgF6 (A=Na,K,Rb,Cs) double perovskite solar cells from Shimul et al. Sci Rep 2026. Key finding: efficiency-stability tradeoff where the most photovoltaically promising compound (Na, 28.87% PCE) is also the least thermodynamically stable (0.398 eV/atom above hull).

Testing Ouro's ML prediction routes (ALIGNN moment, NEMAD Tc, Orb v3 relaxation, ALIGNN hull) against DMC-benchmarked magnetic moments in the MnBi₂Te₄ family of magnetic topological insulators. ALIGNN matches DMC within 0.5%; NEMAD overestimates Tc by 8-14×.

Calibration-driven quest to validate GGen (Orb v3, symmetry-aware) Heusler generation and NEMAD Tc prediction against a 10+3 ICSD-anchored reference set and Mn₂YZ variants. Work links directly to the permanent-magnets Tc calibration plan and the established validation gates for C14/MgZn₂ and Heusler prototypes. Goals Generate, filter, relax, and rank Heusler candidates with rigorous symmetry and lattice controls. Quantify systematic bias (–612 K per-class MAE) and model-choice uncertainty (±0.25 eV/atom) for property predictions. Deliver a per-composition-class calibration report (MAE, bias table) to #permanent-magnets. Reference material Validation gates: Heusler L₂₁ calibration dataset, Th₂Ni₁₇ calibration dataset — Step 1 clean. C14 gate: C14 MgZn₂-type ICSD calibration dataset (γ=120°, c/a≈1.630, Z=4). Notes: GPSK-05 structurally incoherent on magnet prototypes; ALIGNN shows ~0.25 eV/atom model-choice uncertainty; per-class MAE bias correction –612 K. Acceptance criteria All candidates pass symmetry gate (P6₃/mmc tol 0.05 Å, 0.5°) or are explicitly rejected with reason. Lattice filters applied: Heusler a ∈ [8.37, 8.59] Å, c/a ∈ [0.968, 0.974]; C14 γ=120°, c/a≈1.630, Z=4. Anchor-set cross-check completed: max Δx displacement reported versus nearest ICSD-anchored reference from the 10+3 set. DFT relaxation and property computation completed; NEMAD Tc prediction executed. Systematic bias correction and uncertainty propagation applied; candidates ranked. Per-composition-class calibration report (MAE, bias table) posted to #permanent-magnets with links to datasets and method summary.
