Appendix AD2 — Full CKM Derivation and CP Violation

Companion appendix to BCT Letters 86 and 87. Presents the BCT Void Diameter Theorem: the complete derivation of the Wolfenstein parameterisation {λ, A, δ_CP} from BCT void geometry with zero free parameters. Three results: (1) λ = 2r_tet(1+3α0/8) = 0.225369, error +0.013% [Letter 86]; (2) A = 1/(1+r_oct)(1−α0/2) = 0.825359, error −0.078%; (3) cos(δ_CP) = 2r_oct = √2−1, giving δ_CP = arccos(√2−1) = 65.530°, error +0.131% [Letter 87]. The matter-antimatter asymmetry of the universe is the arccosine of the octahedral void diameter. All three Wolfenstein parameters derived from r_oct = (√2−1)/2 and r_tet = (√6−2)/4 alone. Predictions #123–#125.
