This position brief summarizes and contextualizes my larger paper on the Indus script (Without Kings or Conquests: The Indus Script Deciphered and a Civilization Reconstructed). It challenges the long-standing phonetic assumption that has dominated Indus scholarship for over a century, showing why competing linguistic hypotheses (Dravidian, Indo-European, Munda) have consistently failed. The brief presents the empirical challenges to phonetic models (brevity of inscriptions, sign inventory mismatch, positional clustering, and geographic stability), outlines a reproducible framework (computational epigraphy, contextual archaeology, and a tripartite inscription grammar), and situates the Indus script within cross-cultural parallels such as Inca khipu and proto-cuneiform. It highlights the role of the Compression Principle as the unifying mechanism that explains brevity, clustering, and stability, and introduces a civic–ritual model of the script as a symbolic system encoding identity, transactions, cycles, and authority. A comparative table contrasts phonetic hypotheses with the civic-compression model, and the brief concludes with falsifiable predictions for future testing. This report is intended as an accessible companion to the full paper, for both scholarly and public audiences. This report is a companion to my full paper: https://doi.org/10.5281/zenodo.17066226.
