## Definition
**Time asymmetry** describes processes whose evolution distinguishes past from future, commonly through irreversibility, entropy production, causal ordering, or history-dependent state. Biological systems maintain organization through continuous energy and matter exchange rather than static equilibrium.
## Continuity relevance
An emulation may require not only a structural state but sufficient dynamic and historical variables to reproduce how that state changes. U10 modeling uses time asymmetry to keep those constraints visible.
