On Non-Holding in Structural Systems: A Non-Modal Fixation of Configuration

This paper fixes non-holding within a non-modal structural framework. Non-holding is not treated as failure, breakdown, interruption, or absence. It is fixed without causality, temporality, or subject-dependent interpretation. Fixation is not assumed to persist, continue, or be retained. No transition, sequence, or derivation is introduced. The paper does not explain non-holding. It fixes the condition under which fixation does not hold. This paper follows Non-Extension.
