Pre-Modern Constraint Architecture: Convergent Pe Encoding in the Voynich Manuscript, the Ripley Scroll, and Dirichlet Character Space

Three independent pre-modern sources (~1404–1550 CE) converge on the same three-dimensional constraint architecture formalized in the Void Framework. The Voynich Manuscript encodes O/R/α dimensional structure in morphological prefix families (EXP-VOY-04/06/07, n=26, ρ=0.873). The Ripley Scroll maps eight canonical alchemical creatures to Pe regimes with Spearman ρ=0.717 (p=0.046, n=8, EXP-RIPLEY-01). Dirichlet character theory on Z/9Z (§43) encodes the functional equation as alchemical coniunctio: Re(s)=1/2 = constraint boundary = citrinitas. Three sources, no possible communication channel, same abstract structure: Structural Isomorphism #23.
