Kasei-Theory Ⅵ: Structural Boundary［可性論 VI］

Boundary in Kasei-Theory is defined as the structural configuration that determines the range within which connections, updates, and impossibility are fixed. It is not a spatial division, an external limit, or a causal condition, but a configuration fixed under accumulated structural constraints, including the fixation of readers, the stabilization of differences, and the closure of return paths. This paper analyzes boundary as a structural limit within the architecture of the first system of Kasei-Theory. Where readers (readout bandwidths) are fixed and differences are stabilized, return paths close and constraints accumulate. Boundary is fixed as the configuration determined under these conditions and delimits the range within which connections are established, updates occur, and impossibility is fixed. In this framework, impossibility does not signify an external prohibition but an internal configuration fixed when connection paths are structurally closed. Boundary therefore marks the structural limit at which connections, updates, and impossibility are mutually determined. Unlike post-structuralist accounts of deferral or différance associated with Derrida, boundary in Kasei-Theory does not describe displacement but fixes the structural configuration that determines the limits within which applicability and fixation hold. The aim of this paper is not to introduce a new metaphysical principle but to fix the structural limits governing connections, updates, and fixation within the first system of Kasei-Theory.
