Irreversibility Without Temporal Direction

This paper examines irreversibility without temporal direction within a non-modal structural framework. Irreversibility is not treated as entropy increase, thermodynamic asymmetry, temporal progression, or irreversible process. Temporal direction is not treated as the origin of irreversibility, nor as the condition that stabilizes restoration failure. The paper argues that irreversibility remains structurally maintained without temporal equivalence. Temporal direction does not produce irreversibility. Irreversibility is presented as the structural condition under which restoration fails to remain maintained. Irreversibility is not generated through causality, temporality, processual succession, or subject-dependent recovery. Restoration is not treated as reversible persistence, but as maintained readability under constrained structural conditions. The paper develops an interface layer between restoration failure and temporally oriented systems without reducing irreversibility to entropy, process, or thermodynamic evolution.
