Paper CV: Chapter Q Closing the Wolfenstein Parameter A: CKM Completion λ-Propagation Theorem; Acorr = |Vcb|/λ2

Paper CIV established the G2 hop rule nhops = |∆g| + δGen3 and predicted Ahop = |Vcb|/λ2 G2 = 0.827 versus APDG = 0.811, a 2% discrepancy. This paper resolves that discrepancy completely. The 2% gap has two sources: (1) a λ-propagation artifact of 1.5% from dividing by λG2 instead of λobs in A = |Vcb|/λ2; and (2) a residual 0.5% true Gram correction. After removing the λ-propagation artifact: Acorr = |Vcb|/λ2 obs = 0.815. Comparing with APDG = 0.811 ± 0.012: the discrepancy is 0.33σ consistent with zero at the level of the experimental uncertainty on A. The Wolfenstein parameter A is conrmed within experimental precision. The 0.5% residual is a prediction of the true Gram correction from the H+/H−norm asymmetry of the generation 2-forms; when A is measured to < 0.5% precision (expected from future B-physics experiments), this correction will be directly testable. The CKM sector of the framework is declared complete at the level of current experimental precision. A summary of all CKM results is given.
