The Digital Root Fingerprint of the Quran: Evidence across Two Scripts, Three Encodings, and Ten Canonical Readings

This paper reports a digital root structure in the set {3,6,9} specific to the Quranic text. Fourteen experiments across two orthographic layers, three encoding systems, five control texts, and ten canonical readings establish that the fingerprint is text-specific, identity-borne, order-dependent, reading-invariant, and orthographically structured.
