Improve mule classifier: native-NaN + missingness (CV PR-AUC 0.88->0.91, recall 13->15/16)
Aryan Singh +1: Claude Opus 4.8 (1M context)- builder.py: numerics kept as NaN for LightGBM native handling; add missingness indicators + row missing-count; IsolationForest uses a median-imputed copy - train.py: logistic baseline imputes before scaling (NaN-safe) - scoring.py: direction-aware narrative (cleared accounts explain what kept risk low) - rings.py: median-impute features before k-NN similarity graph (NaN-safe) - dashboard: center gauge value; remove fabricated channel/feed-source panels; add real risk-tier breakdown - regenerate model/pipeline/metadata/threshold/feature-list/rings/alert-feed Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>67eae2d
