The Voynich Manuscript Deciphered: A Phonetic Transcription of Spoken Elu-Sinhala

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: 90.9% of 35,916 tokens glossable in English (32,646 tokens); 99.4% matching Sinhala dictionary (Tier 1+2+3); only 0.6% truly unknown (213 tokens); domain clustering in pharmaceutical vocabulary at 101.2x over random (Z=52.7); 26 independent converging evidence lines, combined p << 10^-7.

Includes the full paper (PDF) and the complete 4,591-entry decoded vocabulary (TSV) with English glosses, confidence levels, and Sinhala phonetic forms.

v3 changes: Added Panchavidha Kashaya Kalpana pharmaceutical classification mapping (6 decoded terms map one-to-one onto classical Ayurvedic dosage forms). Added text-image cross-modal convergence (decoded Solanaceae vocabulary independently matches Petersen botanical identifications from illustrations). Added parallel text validation against 8 authentic Bodleian Library medieval Sinhala recipes. Expanded plant identification table (11 species, 698 occurrences). Updated abstract and evidence count (24 to 26 independent lines).

v2 changes: Added cross-language phonotactic validation, rule-freezing documentation, and hostile replication protocol.
