The Collapsing-Structure Spacetime Model (COS-S) introduces a novel approach to quantum gravity. Instead of describing spacetime as a continuous manifold, COS represents it as a network of quantized graph structures. The dynamics of these structures are governed by collapse and transformation processes. Local metric properties are represented by filaments, while global topology is encoded in shells, both associated with quantized operators. A quantized action and a collapse generator formalize the dynamics, producing discrete transitions between graph states. The COS framework integrates key components of high-energy physics, including the Standard Model, supersymmetry, and grand unification. In cosmology, it provides testable predictions for cosmic microwave background (CMB) fluctuations, the spectrum of gravitational waves, and the origin of neutrino masses. Its discrete background can be explored through numerical simulations, complemented where appropriate by modern data-driven analysis techniques to identify complex graph patterns and relate them to empirical data. This entry gives an overview of the full COS program, structured into eleven modules (COS-S, COS-QF, COS-QHF, COS-QD, COS-SM, COS-SUSY, COS-GUT, COS-C, COS-NUM, COS-EXP, COS-TOE). The program aims to present a coherent quantized graph-topological framework that combines mathematical consistency with empirical testability, providing a promising candidate for a unified theory of quantum gravity.
