clickhouse-client --multiquery < 03_anubis_tables.sql
clickhouse-client --multiquery < 04_mv_http_logs.sql
clickhouse-client --multiquery < 05_aggregation_tables.sql
clickhouse-client --multiquery < 06_ml_tables.sql
clickhouse-client --multiquery < 07_ai_features_view.sql

```

## File Descriptions

| File | Contents |
|------|----------|
| `00_database.sql` | CREATE DATABASE |
| `01_raw_tables.sql` | `http_logs_raw` ingest table |
| `02_dictionaries.sql` | ASN geo dict, bot IP/JA4/network reference tables |
| `03_anubis_tables.sql` | Anubis crawler rule tables and dictionaries (UA, IP, ASN, country) |
| `04_mv_http_logs.sql` | Canonical `http_logs` target table + `mv_http_logs` materialized view with full Anubis enrichment |
| `05_aggregation_tables.sql` | `agg_host_ip_ja4_1h`, `agg_header_fingerprint_1h` + their MVs |
| `06_ml_tables.sql` | `ml_detected_anomalies`, `ml_all_scores` |
| `07_ai_features_view.sql` | `view_ai_features_1h` with Anubis enrichment |

| `09_audit_table.sql` | `audit_logs` table for SOC dashboard audit trail |

## 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 prefixes
- `bot_ja4.csv` — Known bot JA4 fingerprints
- `asn_reputation.csv` — ASN reputation labels

## Notes

- `04_mv_http_logs.sql` is the **canonical** version of the MV, superseding the base version
  in `services/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.sql` **must** be changed before production use.
