Structural Analysis of the Indus Valley Script: Positional Lock Architecture and Functional Decipherment Without Phonetic Assumptions — Priority Claim, Structural Ledger, and Interactive Seal Visualizer

Description: Public priority claim and supporting materials for a structural functional decipherment of the Indus Valley script. Analysis applied to the full CISI corpus (2,543 inscriptions, 11,280 tokens, 676 sign types, 31 sites) using Mahadevan concordance sign numbering. 90.5% of all sign tokens functionally assigned across four structural layers without phonetic assumptions and without a bilingual text. All five universal laws of structured information systems confirmed including Zipf R2=0.9901 — the highest value confirmed for any ancient script in the cross-corpus MM analysis. The non-linguistic hypothesis (Sproat 2004) is structurally falsified. Analytical methodology withheld pending peer review. All results reproducible from CISI corpus (yajnadevam/indus-website, GPL-3.0). Files included: (1) Structural Ledger — formula inventory, positional lock map, and four-row analytical ledger for 8 representative inscriptions; (2) Historical Record — public overview of the Indus Valley Civilization, the script, prior scholarship, and MM findings; (3) Interactive Visualizer (HTML) — animated seal analysis tool with sign grid, lock map, and structural readings for 15 representative seals.
