- TrafficAutoEncoder class: symmetric AE (n→64→32→16→32→64→n) with BatchNorm+ReLU - Trained alongside EIF on human_baseline, saved/loaded with model versioning - Score = per-sample MSE reconstruction error, combined with EIF via AE_WEIGHT (α=0.30) - AE latent space (16-dim) used for HDBSCAN clustering instead of raw features - Configurable: AE_WEIGHT, AE_EPOCHS, AE_LATENT_DIM, AE_LEARNING_RATE - Graceful fallback: if torch unavailable or AE fails, EIF-only scoring continues - ClickHouse: ae_recon_error column added to ml_all_scores - Tests: 5 new tests (AE train/score, encode latent, state dict save/load, weight combination) 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.
