A Colossally Abundant Event Reduction of Robin's Inequality with a Residual Zero Obstruction

This preprint studies Robin’s inequality through a formulation based on colossally abundant event states. It derives an event-based reduction and isolates a residual zero-sensitive obstruction within the framework. The manuscript does not claim to prove the Riemann Hypothesis. Its purpose is to document the reduction, clarify the remaining obstruction, and invite technical feedback on the formulation.
