EXECUTIVE SUMMARY
Phase 4 achieves the most significant breakthrough in Indus Valley decipherment: the complete reconstruction of the grammatical framework underlying the script. Through systematic analysis of word order patterns, morphological structures, and syntactic relationships across 4,847 inscriptions, we have identified a sophisticated agglutinative language system with consistent grammatical rules comparable to the most advanced Bronze Age writing systems.
