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).

E255 — Rung 4 as validation and refit, on one candidate (J11, J13.) Its tolerance comes from E251's spread, so it is fixed in its own entry after E251. The loop: DFT cells as in E251; if any ΔE_ord or hull gap is outside tolerance, add every cell to the training set, refit, and rerun E249–E250's rungs on it.
