Research session · Voynich Manuscript

# Session 6: Phase 2: registered tests, brute force, five surveys; book v1.1

A pre-registration framework with surrogates, a 103-language reference, planted-key controls and a held-out split; nineteen hypotheses tested, including substitution and homophonic searches over 187 language samples; five methods surveys (cryptanalysis, linguistics, bioinformatics and signal, imagery, emerging methods). Book v1.1 added Part V.

Session **6** 22 Oct 2026Test0
