Kasei-Theory I.Residuality: Residuality Without Ground

This paper presents residuality within the first system of Kasei-Theory as a non-modal readability maintainability architecture. The paper does not propose a theory of ground, persistence, preservation, survival, remainder, foundational continuity, loss-derived remainder, trace-derived preservation, persistence-derived continuity, origin-derived residue, or transcendental residual order. Instead, it fixes residuality, constrained residuality, configurational differentiation, local maintainability, unreadability, formal residuality, trace non-derivation, and non-totality as distributed structural positions within constrained local readability maintainability. Residuality is not treated as ground, remainder, preservation, persistence, survival, or foundational continuity, but as constrained residuality under which configurational differentiation remains locally maintainable without universal grounding, completed persistence, preserved continuity, origin-derived residue, loss-derived remainder, or total configurational closure. Residuality does not establish ground. Residuality does not establish substance. Residuality does not establish origin. Residuality does not establish preservation. Residuality does not establish completed persistence. Residuality is not remainder. Residuality is not what remains after loss. Residuality remains fixed only as constrained residuality within local readability maintainability. This paper fixes only the local residual conditions under which configurational differentiation remains maintainable without transition into universal grounding, completed persistence, preserved continuity, loss-derived remainder, trace-derived preservation, persistence-derived continuity, or total configurational closure. No subject is presupposed. No foundational structure is established. No universal residual structure is secured. No total configurational closure is completed. This paper is part of Kasei-Theory.
