📈 DistilBERT Fine-tune Progress
Tracks evasion rate before and after each fine-tune on Kaggle T4. Models pushed to HF Hub as
Builder117/distilbert-{detector}-v{round}.
Improvement = evasion rate drop after retraining on adversarial samples.
Reads Red+Blue agent outputs, decides whether to retrain detectors, writes pipeline_decision.json.
Uses ReAct loop with confidence threshold before committing to a decision. Decision history tracked across all rounds.
