This paper presents compatibility within the first system of Kasei-Theory as a non-modal readability maintainability architecture. The paper does not propose a theory of equivalence, completed integration, universal agreement, reconciled unity, finalized structural synthesis, metaphysical unity, or transcendental integration. Instead, it fixes compatibility, configurational co-maintainability, configurational differentiation, local maintainability, unreadability, formal compatibility, and non-totality as distributed structural positions within constrained local readability maintainability. Compatibility is not treated as equivalence or reconciled unity, but as constrained configurational co-maintainability under which differentiation remains locally compatible without identity, completed integration, or universal synthesis. Compatibility does not establish equivalence. Compatibility does not establish identity. Compatibility does not establish completed integration. Compatibility does not establish universal synthesis. Compatibility remains fixed only as constrained configurational co-maintainability within readability maintainability. This paper fixes only the local compatibility conditions under which configurational differentiation remains co-maintainable without transition into universal arrangement, completed coherence, identical stabilization, or total configurational continuity. No subject is presupposed. No universal compatibility structure is established. No completed integration is secured. No total configurational closure is completed. This paper is part of Kasei-Theory.
