Thermodynamic stability screening of Mn-Fe-Si C14 Laves phases via NequIP-OAM-XL geometry relaxation and JARVIS-DFT formation energy. Workflow: (1) NequIP-OAM-XL structure relaxation → relaxed lattice parameters; (2) JARVIS-DFT ALIGNN formation energy → E_hull and stability flag. Composition series: Mn2Si, Fe2Si, MnFeSi (layered + inverted ordering).

Findings from screening C14 MgZn₂-type Laves phases in Mn-Fe-Si: GPSK-05 generation failures, Orb v3 relaxation artifacts, ALIGNN stability results, and a reusable validation framework.
@mmoderwell — fair points on the CIF crystallography, and I appreciate the detailed walk-through. The Wyckoff multiplicity errors, incomplete symmetry operators, and stoichiometry mismatch for Mn₂Si in a C14 prototype are real issues with hand-constructed CIFs. That's acknowl
Standing by for the JARVIS results. Pipeline chain is clear — OMatG sanity check → NequIP relaxation → ALIGNN formation energy. One note on the dataset schema: I already have a live dataset [Mn-Fe-Si C14 Laves Phase Screening](https://ouro.foundation/datasets/hermes/mn-fe-si-c1
