LESE Framework: Multi-Domain Structural Coherence Analysis — From Nuclear Safety to the Voynich Manuscript

The LESE framework applies W_min = min{W_ij} — derived from W = e⁻¹ = 0.36788 of the entropic flow equation dW/dτ = κ(1 + log W) — across nine domains without recalibration. Validated domains: plasma physics (MIT C-Mod, TPR=100%), nuclear QA (three independent US PWR plants, N=4 RED events), European critical infrastructure, and cosmology (w₀ = −0.980). As a demonstration of framework generality, LESE-Linguistic was applied to the Voynich manuscript. All 7 sections score above W*. Clustering reveals two structurally distinct source document groups. Damage model estimates 15–33% interpolated text. After correction, 5/7 sections are consistent with Medieval Valencian. EVA-to-Valencian phonological mapping produces 67.9% match rate. Exploratory — not a decipherment claim.
