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.

v8 (Decoder expansion and structural analysis): Three new rules added: word-final o→a (Rule 31, +644 tokens), cf→ch (Rule 32), cs→s (Rule 33). Gloss rate improved from 90.7% to 94.4%. Total known tokens 99.7%, unknown reduced to 0.3%. Illegal consonant clusters reduced from 123 to 2. Systematic naming conventions identified. Three zodiac hypotheses tested and refuted. Biological section reinterpreted as gynecological pharmaceutical formulary.

Key results: 94.4% of 35,916 tokens glossable, 99.7% dictionary match, 12/12 validation scripts pass.
