Bian's 2008 chapter-11 percentages are a calculation error: substituting Figure 10.1 into equation (11.5) recovers the known kappa=1 control 348002/405405 and not the reported 0.9544 and 0.9774, two measured oracles are retained, and no higher-derivative zeta constant is claimed.

Guiding Question
What do Bian's 2008 higher-derivative form-factor percentages actually compute, and can a first-principles reconstruction of xi'''/xi'' coefficients support a higher-derivative zeta constant?
Method & Verification
Figure 10.1 coefficients were substituted exactly into equation (11.5), recovering 348002/405405 at kappa=1 (the known control) and not the reported 0.9544 and 0.9774 at kappa=2 and 3.

Editorial Notes
No HuntSpec or HANDBACK at the pin. Question filled from MISSION.md plus the case-log discrepancy. Evidence grade is ordinary mathematical derivation for the headline calculation error; completed-CUE and Dirichlet-recurrence oracles are measured and are retained as supporting checks, not as the grade of the discrepancy claim.
