Core Structural Layer: Irreversibility Without Temporality — A Non-Modal Fixation

This paper presents a non-modal fixation of irreversibility without temporality. Irreversibility is not treated as temporal direction, entropy increase, processual asymmetry, or thermodynamic evolution. It is fixed without causality, temporality, subject, meaning, or restorative equivalence. The text delimits the structural condition under which restoration fails to be constituted without transition, recovery, or return. Irreversibility is fixed as failure of restoration without return. Restoration is not removed but fails to be constituted. Recovery is not lost but fails to be established. Irreversibility is not disappearance, annihilation, transformation, or irreversible process. No subject is introduced. No meaning is introduced. No representation is introduced. No temporality is introduced. No causality is introduced. This paper is part of the Core Structural Layer within Kasei-Theory.
