Kagen in the Non-Modal Structural System — A Structural Repositioning of Fixation, Boundary, and Collapse

This paper introduces Kagen (可限) as an internal structural limit within the non-modal structural system. Kagen is fixed as the condition under which fixation does not hold, without relation, duality, or externality. Fixation is fixed and holds, while reading, boundary, and collapse are fixed within Kagen without derivation or correspondence. No causality, temporality, or subject is introduced. No unification is introduced. This paper does not extend or unify existing structures but establishes the structural repositioning of fixation, boundary, and collapse within Kagen.
