Dynamic Harmony Structural Stress-Test Series. This paper evaluates the problem of unifying microscopic quantum dynamics with macroscopic classical behavior. The analysis examines whether proposed mechanisms linking these scales satisfy the structural conditions required for genuine emergence within the Dynamic Harmony framework. Using the Phase Non-Substitutability Test introduced in Paper 0 and the architectural boundary criterion developed in Paper 0B, the paper analyzes whether the transition from microscopic quantum dynamics to macroscopic classical systems represents a true architectural redefinition or remains a configurational rearrangement within an existing state space. The analysis clarifies the structural conditions under which unified dynamical descriptions can account for the emergence of stable macroscopic organization. This paper forms part of the Dynamic Harmony Structural Stress-Test Series, a research program that evaluates major theories of emergence across physics, biology, and complex systems through adversarial structural analysis.
