Status as a Compensatory Layer_ Invariant Substitution Under Measurement Opacity

This paper establishes a general structural law governing coordination in persistent systems. Any system that persists over time must select among competing candidates according to a scalar invariant that determines stability. When direct evaluation of this invariant is feasible at the required coordination rate, selection proceeds by measurement. When it is not, selection must be routed through an indirect substitute mechanism. We prove that such substitution is forced under conditions of measurement opacity, defined by the imbalance between candidate generation and evaluation capacity. The resulting compensatory layer does not replace the governing invariant but substitutes for access to it. Its activation, reinforcement dynamics, drift, and collapse follow mechanically from repeated selection under constrained evaluation. The result is domain-independent and applies to physical, biological, ecological, and human coordination systems. No appeal is made to psychology, social norms, or institutional behavior; the dynamics follow from persistence, bandwidth, and selection alone.
