Phase Architecture and the Dynamics of Coherent Observation

This article presents the third contribution in the Phase Architecture series and provides a structural interpretation of quantum observation within a phase-dynamic framework. Building on earlier work introducing phase displacement (Δφ) as a regulator of coherence and phase modulation as a stability mechanism, the present study examines measurement as a physically constrained interaction between coherent systems and external fields. Observation is described as a coherence-selective process governed by bounded phase displacement, where discrete outcomes correspond to stability conditions within defined phase thresholds. The framework does not modify the predictive formalism of quantum mechanics but offers a structural account of how stability, containment, and state selection arise under phase constraints. The analysis is positioned in relation to established approaches, including the von Neumann measurement scheme, decoherence theory, and the Everett interpretation. This work completes the foundational development of the Phase Architecture framework.
