Kasei-Theory: Uniqueness of Structural Dependency

This paper formalizes the dependency structure of Kasei-Theory as a strictly ordered configuration. The structure is defined as a strict partial order and shown to form a total chain. It admits exactly one linear extension and excludes alternative configurations. This uniqueness is not interpreted temporally or causally. It does not describe a process but fixes a structural condition under which no alternative ordering is possible. The result establishes a unique configuration that cannot be rearranged, substituted, or extended without violating its defining constraints. Uniqueness is fixed.
