v2 — adds Experiment 14: Random Encoding Stress Test. Unified preprint integrating fourteen computational experiments from the d369 project. Supersedes Papers I–VI. NEW in v2: Experiment 14 tests 33 random encodings (unique values, no duplicates) against the Quran. Result: 0/33 random encodings achieve p < 0. 007 (Special-6's level). Mean 3, 6, 9 proportion under random encoding = 31. 3% (below chance). This eliminates the objection that "any encoding produces the fingerprint. " The Quran carries a digital root structure in 3, 6, 9 that is text-specific, system-independent, order-dependent, content-borne, and indivisible. Five control texts (Bukhari, Ibn Arabi, Mu'allaqat, Hebrew Torah, shuffled Quran) all fall at or below chance. No theological claim is made.
Emad Suleiman Alwan (Sat,) studied this question.
