Unified preprint integrating thirteen computational experiments from the d369 project. Supersedes Papers I–VI. We test whether the Quran carries a statistically significant digital root structure in the set 3, 6, 9 using two independent encoding systems (classical Abjad and the novel Special-6). Under Special-6, 51/114 Surahs (44. 7%) yield digital roots in 3, 6, 9 (p = 0. 007, Cohen's h = 0. 234). A transformation map (G14) reveals a three-layer tree architecture with four self-preserving roots 1, 3, 6, 9 (p = 0. 00013). Five control texts — Bukhari, Ibn Arabi, Mu'allaqat, Hebrew Torah, and shuffled Quran — all fall at or below chance. The Torah shows no G14 architecture (p = 0. 068). Verse counts carry no signal (p = 0. 652). All eight primary tests survive FDR correction. The fingerprint is text-specific, system-independent, order-dependent, content-borne, and indivisible across 114 Surahs. No theological claim is made.
