Time as Retention Without Return Under Asymmetry (The Non-Modal Structural System II)

This work presents a structural fixation of time. Rather than treating time as flow, sequence, parameter, or dimension, this text locates time within a prior structural condition. Irreversibility is not introduced as a physical or temporal property, but fixed as the absence of integration and return under structural persistence. However, irreversibility alone does not determine direction. To resolve this, asymmetry is introduced as the failure of equivalence under structural reversal. This does not presuppose any operation, transformation, or temporal inversion, but marks the impossibility of preserving equivalence across opposing structural configurations. Within this framework, time is not derived, measured, or generated. It is fixed as the condition under which retention holds without return under asymmetry. This approach does not propose an alternative model of time, but repositions time as a consequence of structural constraints that precede physical description.
