Convex hull of the Cl-Na structures in Ouro's shared structure database on the ORB v3 surface (MP2020-corrected), leaving out generated P1 structures, after Matra-Genoa explored 3 stoichiometries and added 3 relaxed structures. 1 of this run's formulas are on the hull and 2 within 150 meV/atom. Model-generated; not DFT-validated. Generated with Matra-Genoa (De Breuck et al., npj Comput. Mater. 12, 60 (2026), doi:10.1038/s41524-025-01940-8) and relaxed with Orb-v3 (arXiv:2504.06231) via TorchSim (doi:10.1088/3050-287X/ae1799).
