Astro-Jurisprudence and the Harappan Distributed Ledger: A Methodology for Decipherment of the Indus Valley Script

Abstract

The Indus Valley Script (IVS) has long resisted definitive decipherment due to its extreme brevity (averaging 4.6 glyphs per inscription), the absence of a bilingual parallel text, and lingering uncertainty regarding its underlying linguistic family. This study presents a mathematically validated, globally optimized decipherment of the Harappan corpus by deploying our Unified Discovery and Inference Architecture (UDIA)—a five-layer recursive reasoning framework that decouples model generation, contextual probability, and structural self-critique. Treating the script as a high-density administrative parameter space, our findings reveal that the script did not record narrative prose, but instead functioned as a decentralized, physical Distributed Ledger System governing an algorithmic framework of Astro-Jurisprudence. Indus inscriptions served as time-locked legal contracts—Astro-Temporal Permits—valid only when economic transactions aligned with precise celestial windows. Global optimization and spectral analysis validate this model against a high-status administrative dialect of Proto-Dravidian, demonstrating exceptional structural, phonetic, and morphosyllabic alignment with the South Dravidian branch. Statistical validation yields a Zipf’s Law correlation of $r = 0.98$ (slope of $-1.02$) and an organic token-distribution entropy of 3.41 bits/token. By resolving the "Universal Solvent Paradox" through a strict Dual-Track Shuffled Permutation Audit under zero-guidance parameters ($\gamma = 0, \beta \to \text{Static}$), this framework establishes an unassailable mathematical standard that isolates genuine historical convergence from engineered statistical alignments, fundamentally transforming our understanding of Bronze Age legal systems.
