Kasei-Theory I.Delimitation: Delimitation Without Boundary

This paper presents delimitation within the first system of Kasei-Theory as a non-modal readability maintainability architecture. The paper does not propose a theory of boundary, separation, prohibition, exclusion, terminal restriction, completed configurational partition, boundary-derived separation, constraint-derived restriction, non-closure-derived incompletion, or transcendental delimitation order. Instead, it fixes delimitation, configurational delimitation, configurational differentiation, local maintainability, unreadability, formal delimitation, and non-totality as distributed structural positions within constrained local readability maintainability. Delimitation is not treated as boundary, separation, or exclusion, but as constrained configurational delimitation under which configurational differentiation remains locally maintainable without universal separation, completed confinement, prohibition, restriction, or total configurational closure. Delimitation does not establish boundary. Delimitation does not establish exclusion. Delimitation does not establish prohibition. Delimitation does not establish terminal configurational partition. Delimitation remains fixed only as constrained configurational delimitation within readability maintainability. This paper fixes only the local delimitation conditions under which configurational differentiation remains maintainable without transition into universal restriction, completed separation, boundary-derived partition, constraint-derived restriction, or total configurational integration. No subject is presupposed. No exclusionary structure is established. No universal delimitation structure is secured. No total configurational closure is completed. This paper is part of Kasei-Theory.
