Representational Gravity and Localization, Physical Descriptions as Non-Fundamental Patterns in Boundary-Confined Structure

This work establishes a purely structural framework for the interpretation of classical physical descriptions in boundary-confined systems. No physical entities are assumed to be fundamental. Concepts such as gravity, particles, fields, trajectories, origin, and expansion are treated strictly as non-ontological descriptions of stable structural patterns.A space of admissible boundary partitions is defined, together with an associated attractor class induced by latent combinatorial asymmetry. The partition labeled 5:27:68 is introduced solely as a structural marker identifying this class, not as a numerical law, dynamical outcome, or physical constant.The analysis shows that classical physical language is representationally unavoidable yet structurally constrained: it remains coherent only within the attractor class. Outside this domain, classical descriptions lose stability and interpretative consistency.The results are structural in nature and do not introduce dynamics, spacetime, quantum states, probabilistic postulates, or physical mechanisms. The paper closes the representational analysis of structurally stable classical descriptions and delineates its intrinsic domain of validity.
