Description

The Voynich Manuscript (Beinecke MS 408, carbon-dated 1404-1438 CE) is identified as a 15th-century Elu-Sinhala pharmaceutical text - a teaching manual recording a physician's spoken instructions for Ayurvedic preparations. The writing system is a bespoke abugida mapping 27 EVA characters to 14 Sinhala phonemes.

Key results: 90.7% of 35,916 tokens glossable in English; 99.3% matching Sinhala dictionary; only 0.7% truly unknown.

v4 changes - Adversarial fairness audit:

  • Equalized pharmaceutical vocabulary: 115 concepts x 6 languages, max/min ratio 1.25
  • Fair cross-language test: Sinhala matches 13x more pharmaceutical terms than any other language (Z=1.66, honestly below 2.0 significance threshold)
  • Panchavidha Z=10.5 downgraded to CIRCULAR: 3/6 terms not in Sinhala dictionary. Non-circular test: external pharma Z=3.5
  • 8 new validation scripts with full random-decoder comparisons
  • Failed tests documented: folio clustering (Z=0.2), recipe sequencing (all metrics failed)
  • 3 STRONG PASS pillars: SOV syntax (Z=7.04), pharmaceutical collocations (0/10 random), external pharma vocabulary (Z=3.5)
  • 3 cross-modal convergences (inherently random-proof)
