"""
Verify CLEAN Enzyme Classification Results (Paper Tables 1-2)
This verifies the hierarchical loss-based conformal prediction on CLEAN data.
Uses pre-computed distance data (clean_new_v_ec_cluster.npy).
Expected results (from paper):
- New-392 dataset: Conformal achieves better F1/ROC-AUC than MaxSep/P-value baselines
- Risk is controlled at target alpha level
Note: Full CLEAN evaluation requires the CLEAN package and model weights.
This script verifies the conformal calibration component.
