Two insights consolidate the nucleation narrative into a single coherent account. First: the Fano valve twist τ = arccos(1/√7) = 67.79° is Niven-irrational — it is provably not a rational multiple of π. The proof is elementary: if τ were rational in units of π, then e^(iτ) would be a root of unity, requiring its character sum 2cos(τ) = 2/√7 to be a rational integer; but 2/√7 is irrational. Therefore R(τ)^n ≠ I for any n, the twist never closes, and any lattice demanding this twist is geometrically frustrated in flat space. The unique resolution of this frustration is hyperbolic geometry κ = −1: the {7,3} tiling is the only tiling that can accommodate τ = arccos(1/√7) at every vertex. The transition to hyperbolic geometry at the Fano valve is therefore categorical, not gradual: flat space cannot even approximately accommodate the Niven-irrational twist, so the geometry must be fully hyperbolic wherever the twist is present. Second: the mass asymmetry δM/M ≈ 6.1×10 ¹ ⁻ ⁰ necessarily causes an off-center collision. H , the ⁻ antimatter black hole, is in a more advanced phase of annihilation than H : in the CPT-conjugate ⁺ parent spacetime, H 's time runs opposite to H 's, so H has already moved further along its trajectory. ⁻ ⁺ ⁻ H collides with where H ⁺ ⁻ was, not where it is. The impact parameter b δM/M decomposes into two ∝ orthogonal components in the 7D parent spacetime: a polar component b_ generating the Genesis tilt ⊥ θG₂ = 4.054°, and an azimuthal component b_ generating the twist τ = 67.79°. Their ratio τ/θG₂ = ∥ 16.72 ≈ 17 is independently identified in Paper CXVIII as the Dehn surgery slope of the hyperbolic knot created by the twisted valve — an internal consistency check. The angular momentum of the off-center collision is the engine of the spiral lotus unfolding of the universe, and the collision axis is the origin of the CMB anomalies.
