ISOA–SSCL: A Regime-Dependent Control Framework for Economic Systems (v1.0)

Modern economic policy repeatedly encounters a paradox:identical interventions often produce stable yet sharply divergent outcomes across economies. This work demonstrates that such divergence is not primarily caused by data noise, behavioral anomalies, or model failure.Instead, it arises structurally from regime-dependent control dynamics. Grounded in the Singularity Seed Cycle Law (SSCL), the framework reframes economic systems as controlled processes whose responses depend on their active control regimes.Within this view, policy effectiveness is inherently regime-relative rather than universally optimal. The record includes: A full theoretical control framework (PDF) A one-page regime lens for rapid understanding and citation An executable Python demonstrator showing regime divergence under identical policy inputs This framework is model-agnostic, ideology-independent, and designed for long-term reuse across macroeconomics, policy analysis, economic governance, and complex systems research. Related regime-based frameworks in Chemistry, Biomedical Systems, and Peace Studies are referenced to demonstrate cross-domain structural consistency.
