Abstract

Scientific models are commonly evaluated in terms of prediction, explanatory power, and empirical adequacy. Yet such evaluation presupposes a prior structural condition: that the candidate state remains admissible under the constraints defining its representation. This paper argues that structural permission precedes dynamical interpretation. A state that violates its defining constraints does not reveal exotic behaviour; it dissolves the referential frame required for behavioural analysis. The thesis introduces no ontology and asserts no new physical law. It isolates a minimal condition of intelligibility operative wherever modelling occurs.
