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).
