This paper presents a non-modal structural fixation referred to as non-extension. Non-extension is not treated as limitation, termination, or incompleteness. It is approached without causality, temporality, or subject-dependent interpretation. Within this formulation, the system does not extend, continue, or develop. No transition, sequence, or derivation is introduced. What is fixed does not lead beyond itself. The paper does not propose an explanatory model. It fixes a structural condition under which no further configuration follows.
