Eligible analytical characterization data were not found in the main paper. The study explicitly states that its compositions were not synthesized or measured and reports optimization results derived from Materials Project shear-modulus data, a previously published high-entropy-alloy hardness dataset, and computational oracles, surrogates, and estimators rather than source-owned analytical measurements. The paper refers to a separate Supporting Information document, but no separate Supporting Information file was available on the ChemRxiv article page when acquired
