Triple-voice ensemble architecture: - EIF (non-supervisé, anomalies zero-day) - Autoencoder (non-supervisé, corrélations non-linéaires) - XGBoost (supervisé, patterns connus + feedback SOC) XGBoost implementation: - Trained on historical ml_all_scores labels (NORMAL=0, HIGH/CRITICAL/DENY/KNOWN=1) - Weekly retraining (XGB_RETRAIN_INTERVAL_H=168), min 100 labels required - Score = predict_proba, combined via meta-learner: (1-β)*(EIF+AE) + β*xgb_prob - Configurable: XGB_WEIGHT (β=0.20), XGB_MIN_LABELS, XGB_RETRAIN_INTERVAL_HOURS - Graceful fallback: if xgboost unavailable or labels insufficient, EIF+AE only - ClickHouse: xgb_prob column added to ml_all_scores - Tests: 4 new tests (availability, train/predict, meta-learner, save/load) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Prerequisites
Place CSV data files in /var/lib/clickhouse/user_files/:
iplocate-ip-to-asn.csv— IP-to-ASN mapping (from IPLocate)bot_ip.csv— Known bot IP prefixesbot_ja4.csv— Known bot JA4 fingerprintsasn_reputation.csv— ASN reputation labels
Notes
04_mv_http_logs.sqlis the canonical version of the MV, superseding the base version inservices/correlator/sql/init.sql. It includes full Anubis enrichment.- All migrations are idempotent (use
IF NOT EXISTS/IF EXISTS). - Anubis dictionary passwords in
03_anubis_tables.sqlmust be changed before production use.
