Kasei-Theory I.Unreadability: Unreadability Without Absence

This paper presents unreadability within the first system of Kasei-Theory as a non-modal readability maintainability architecture. The paper does not propose a theory of absence, inexistence, negation, inaccessible nothingness, failed cognition, dissolved configurational disappearance, originary form, external unreadability, or transcendental unknowability. Instead, it fixes unreadability, configurational unreadability, configurational differentiation, local exposure, non-completed readability, local delimitation, unreadability limitation, and non-totality as distributed structural positions within constrained local readability maintainability. Unreadability is not treated as absence, exteriority, or failed cognition, but as constrained configurational unreadability under which differentiation remains locally exposed without universal readability, completed interpretation, cognitive failure, originary form, or total configurational closure. Unreadability does not establish absence. Unreadability does not establish exteriority. Unreadability does not establish total inaccessibility. Unreadability does not establish terminal configurational negation. Unreadability does not establish unity. Unreadability does not establish multiplicity. Unreadability does not establish originary form. Unreadability remains fixed only as constrained configurational unreadability within readability maintainability. This paper fixes only the local unreadability conditions under which configurational differentiation remains exposed without transition into universal readability, completed cognition, originary form, external absence, or total configurational stabilization. No subject is presupposed. No inaccessible exteriority is established. No universal unreadability structure is secured. No total configurational closure is completed. This paper is part of Kasei-Theory.
