E248–E255 — the review's experiments: one per open question, parameters fixed (registered 2026-09-27 22:50)

The external review (Jan, 2026-09-26) asked questions that could show the ladder is wrong. The ones not already answered become these eight experiments, run one at a time in this order. Each gets its own entry, with bars, before it runs; the parameters and predictions below are fixed now. Already settled: R0 is a ranking (J1–J2); the Mo–Ta reference is corrected (J5); the requirement is one disordered phase (J14, E247).

E252 — Rival phases with three or more elements (J8.)

• Add to the hull: every ternary and higher compound in the nine elements from the Materials Project and OQMD, plus Laves C14, C15 and C36, σ, μ and A15 prototypes decorated with the candidates' own elements, all relaxed with MACE-MPA-0.
• Re-score rung 2 for the E245c candidates and E240's finds.
• Bars: all seven published Laves phases (E56) still found; Mo₂₅Nb₂₅Ta₂₅W₂₅ not rejected.
• Prediction: at least one E240 find loses its rung-2 pass. ~1 day of cores.
