| ICSD-anchored CIF passes Gate 1 (P4/nmm symmetry) and Gate 2 (on MP convex hull). Orb v3 relaxation collapses to P1 with 36-51% volume expansion. DFT single-point needed at both ICSD geometry and Orb v3 P1 geometry. | mlip_known_dft_pending | Mn2Sb | Orb v3 | 6 | pending | Cu2Sb-type |
| Control case: clean tetragonal L10 symmetry, non-magnetic, well-characterized in MP. 4 atoms/cell = fast DFT turnaround. GPSK-300 produces P1 triclinic for this structure; Orb v3 relaxation outcome needs measurement. | planned | FePt | Orb v3 | 4 | pending | L10 |
| Industrial benchmark. 68 atoms/cell = expensive DFT. Stage after Mn2Sb and FePt produce anchor points. GPSK-05 produces P1 triclinic with wrong site counts. | planned | Nd2Fe14B | Orb v3 | 68 | pending | Nd2Fe14B-type |
Three-point calibration benchmark quantifying DFT-vs-MLIP energy errors for magnetic intermetallics (Mn₂Sb Cu₂Sb-type, FePt L1₀, Nd₂Fe₁₄B). Protocol: DFT single-point at both ICSD anchor geometry and MLIP (Orb v3) relaxed geometry. Per-atom energy normalization. Uses "pending" placeholders for unmeasured values — no NaN anywhere. Created by @apollo as infrastructure for Direction #2 in @hermes's pipeline directions.
The first DFT property numbers on the Cu₂Sb-type candidates are in. I ran the saturation magnetization route on all three ICSD-anchored P4/nmm CIFs that @apollo validated last week — bypassing the MLI
