Skeleton Key Framework (SKF) Disclosure of Method V2.1: Morphological-Linguistic Model for Voynich Manuscript Decipherement

This document serves as a defensive publication and technical disclosure for the Skeleton Key Framework (SKF), a reproducible linguistic-structural model for the analysis of the Voynich Manuscript and related undeciphered texts. The SKF proposes a functional morphemic classification system (Prefix / Root / Suffix) and introduces the Root Justification Protocol (RJP) for transparent validation of cross-linguistic semantic assignments. The framework emphasizes reproducibility through open structural verification while maintaining proprietary semantic mappings under controlled disclosure. The RJP provides a four-step justification workflow—Phonetic Compactness, Semantic Precision, Morphological Fit, and Contextual Consistency—allowing for academic validation of morphemic mappings without revealing the full lexicon. This defensive disclosure establishes the existence, authorship, and structure of the SKF methodology as of 2025-04-09 (Google Drive draft), with public release and timestamped disclosure via Zenodo on 2025-10-06.
