Conditional Irreversibility and the Emergence of the Time Arrow from Vacuum Recomposition presents a medium-based physical criterion for when reversible dynamics become irreversible. The work distinguishes mathematical time-reversal invariance from physical reconstructibility, proposing that the arrow of time emerges only when the vacuum medium can no longer recompose a previously coherent configuration after coherence is lost through dispersion, phase decorrelation, or leakage into non-recomposable vacuum modes. The paper includes a mode-coupling toy model and threshold analysis to show how irreversible behavior can arise without breaking fundamental reversibility.
