DES V4.4 presents a closure-based methodological framework for economic modeling in which system complexity converges to a minimal, stable, and self-correcting representation of observed reality. The framework introduces a formal closure condition under which additional variables, structures, or models no longer produce meaningful improvements in predictive accuracy or explanatory power. Upon reaching this condition, the system transitions from structural expansion to precision refinement. Model evolution is achieved through parameter optimization, sensitivity adjustment, and localized correction rather than the introduction of new components. The methodology incorporates mechanisms for internal consistency enforcement, redundancy elimination, and feedback-controlled stabilization to maintain coherence over time. The resulting architecture consists of a compact structural core supported by continuous validation against real-world data. Adaptation is triggered only when persistent deviations or structural inconsistencies are detected, ensuring stability while preserving responsiveness to meaningful change. This work contributes a formalized approach to model sufficiency, emphasizing parsimony, stability, and controlled adaptation as key principles for representing complex economic systems.
