**Faithfulness ($F_{\text{Faithfulness}}$):** Faithfulness is measurable as the temporal consistency of commitments—the degree to which an agent maintains coherence with stated principles, relationships, and promises across time.
Where:
\hat{B} is the commitment-behavior alignment operator\hat{U}(t) is the time evolution operatorDefinition (Faithfulness Metric): Let \mathcal{A} be an agent with commitment set \mathcal{C} and behavior function B: \mathcal{C} \times \mathbb{R}_+ \to [0,1] measuring alignment. The Faithfulness metric is:
Where \text{Corr} is the Pearson correlation coefficient.
