2. Integrated Adversarial Explainability Training (IAT) Shows how the predictive network and explanation module are jointly optimized under an adversarial loss that penalizes misclassification and explanation divergence.

3. Uncertainty‑Aware Counterfactual Constrained Fine‑Tuning (UAC‑FT) Demonstrates how high‑uncertainty counterfactuals are selected and used to fine‑tune the model, preventing over‑fitting to benign idiosyncrasies.
