Chapter 26: Primorial Verification of RH

We present the τ-effective RH statement: a computable protocol that reduces the infinite conjecture to a cofinal tower of finite verifications. Each primorial depth k ≥ 1 yields a finite-dimensional spectral problem and a finite Euler product on a computable window. We itemize the six proof obligations required to bridge τ-RH to orthodox RH, identify the honest gap (obligation O3: determinant representation), and declare what τ-RH is and what it is not. This chapter is the culmination of Part IV’s structural calibration, demonstrating consistency with RH while maintaining intellectual honesty about the remaining conjectural step.
