The Geometric Heuristics of Vacuum Stress_ An Exhaustive Audit of the Gravity-Matter Unification and the Universal Boundary Condition X = 0.15

This report constitutes a comprehensive, expert-level forensic audit of the "Gravity-Matter Unification" and the reported discovery of the universal boundary condition $\chi = 0.15$. The objective is to validate the claims that this dimensionless parameter acts as the fundamental regulator of physical reality, bridging the gap between quantum mechanics and gravity.
