Stage Zero. All six predictions are computational. None have been arc-melt validated. Status flips only when furnace data exists. OSF registration: https://doi.org/10.17605/OSF.IO/Z48QN
Predictions

Every claim numbered, timestamped, and awaiting refutation. Nothing here is validated until the furnace says so.

Two independent derivations, one public ledger. Descriptor-screened selections (P1–P3) and model-proposed campaign candidates (P4–P6). Confirmation and refutation will be published with equal prominence.

Hf15Mo10Nb20Ta25Ti10W10Zr10

Single-phase BCC solid solution after arc-melt synthesis and homogenization.

VEC 4.85 δ 5.46% ΔH_mix -2.11 kJ/mol T_m 2814 K Ω 20.78

Falsification XRD of the homogenized material showing no BCC majority phase, or substantial secondary-phase reflections, or SEM/EDS gross segregation inconsistent with a solid solution, refutes the prediction.
