**Patience ($F_{\text{Patience}}$):** Patience is measurable as the temporal horizon of coherent planning and the capacity to maintain coherence across delayed gratification intervals. It is the temporal extension of coherence.
Where \hat{U}(t) = e^{-i\hat{H}t} is the time evolution operator and \hat{C} is the coherence operator.
This measures the time-integrated coherence under evolution, discounted by \delta.
Definition (Patience Metric): Let \mathcal{A} be an agent with temporal modeling capacity. The Patience metric is:
Where:
\delta > 0 is the discount rate (estimated from behavior)\mathbb{E}[C(\mathcal{A}, t) | \mathcal{A}(0)] is expected future coherence given current state
