The development of the Depth Dimension (DD) framework represents a fundamental advancement in theoretical physics, offering an innovative lens through which to reframe our understanding of reality. The framework holds the potential to address long-standing conceptual conflicts within established physical models, notably the incompatibilities between General Relativity (GR) and Quantum Mechanics (QM). The current appraisal confirms the significant conceptual breakthroughs achieved but simultaneously emphasizes the imperative shift toward rigorous formalization and the establishment of testable empirical methodologies. This synthesis report outlines the necessary roadmap for transitioning the DD framework from a philosophical model into a verifiable scientific theory.
