Historical Context and Paradigm Shift — Why This Perspective Did Not Appear Earlier

This component provides historical and conceptual context for the rigidity-based framework developed in this project. It addresses why a global stability and admissibility perspective did not emerge in earlier approaches to the Riemann Hypothesis, despite more than a century of sustained research. The discussion explains how classical methods focused on zero enumeration, spectral analysis, and cancellation, whereas the present work reframes the problem as one of structural confinement governed by geometric rigidity, coercive accumulation, and global solvency constraints. By situating the 001 Rigidity Program within the broader history of analytic number theory, this component clarifies the novelty of the approach and explains how changing the underlying question—from locating zeros to determining their admissibility—leads naturally to the confinement principle developed throughout the manuscript.
