This paper introduces the Interface Constraint Framework (ICF) to analyze causal and informational accessibility across non-isomorphic descriptive layers. The central claim is that any system operating across such layers cannot be structurally neutral when connected by non-invertible interfaces. “Freedom” is defined not as a metaphysical entity or value claim, but as a structural locus—a remainder produced by mapping incompleteness and multi-realizability. The framework establishes normative indispensability and exchange costs between causation and information without reliance on advanced mathematics.
