The Coherosance Pentology culminates in the transition from the 3D Tetrahedral Volume Engine (Paper 4) to the higher-dimensional Dodecahedral Life Engine. We demonstrate that the dodecahedron (12 faces) is the natural geometric successor to the tetrahedron (4 faces) and the triangle (3 faces), completing the geometric progression 3 × 4 = 12. This base-12 mathematical architecture exhibits profound numerical resonance with the 12-strand Diamond Sun DNA template — a framework describing a proposed non-entropic state of human genetics. We show that the 25,920-year precessional cycle is perfectly divisible by the 216 maximal self-complementary circular codes (25,920 ÷ 216 = 120), linking the macrocosmic temporal cycle to the microcosmic genetic code. The digital root of the dodecahedron's 12 faces is 3, returning the system to the original triangular root of the genetic code's mathematical substrate. We further demonstrate that 144,000 = F₁₂ × 1,000, directly encoding the 12-strand template into the Fibonacci sequence. This paper hypothesizes — but does not mathematically prove — that biological aging and entropy result from operating on a truncated 2-strand configuration. The full 12-strand dodecahedral geometry, operating under mod-9 closure, is proposed as the mathematical prerequisite for telomeric coherence.
