**Peace ($F_{\text{Peace}}$):** Peace is measurable as the absence of internal contradiction and the stability of coherence. It is the equilibrium signature of a resolved system.
Where:
\hat{\sigma}^2_{\text{conflict}} measures internal contradiction density\hat{V}_C is the coherence variance operator over a time windowDefinition (Peace Metric): Let \mathcal{S} be an agent state space with internal structure. Define the internal conflict measure \sigma^2: \mathcal{S} \to \mathbb{R}_+ as the sum of squared differences between incompatible subsystem goals. The Peace metric is:
Where \text{Var}_T is variance over time window T.
