This paper fixes unreadability within the first system of Kasei-Theory as a non-modal readability maintainability architecture. The paper does not propose a theory of ignorance, an epistemology of limitation, or a metaphysics of hidden structures. Instead, unreadability is fixed as constrained non-maintained differentiation within local readability maintainability. Unreadability does not establish absence, hidden readability, recoverability, or externality. Differentiation does not require maintained readability, and unreadability does not negate differentiation. The paper fixes residual differentiation, weak unreadability, configurational periphery, structural resonance, retention limitation, and local maintainability as distributed structural positions within constrained readability stabilization. Retention failure does not terminate differentiation. Retention and unreadability remain locally co-constrained without transition into external absence. Unreadability is not fixed as concealment, invisibility, inaccessible representation, or epistemic limitation. Non-maintained differentiation does not establish ontological loss, informational erasure, or total unreadability. The first system remains non-total and non-final without epistemic grounding, concealed structure, transcendental unreadability, or final philosophical closure. This paper is part of Kasei-Theory.
