f4ffe3410a perf(clickhouse): P1 — partition + skipping indexes sur ml_detected_anomalies, http_logs, agg_host_ip_ja4_1h 
Problème : toutes les requêtes du dashboard WHERE detected_at >= now() - INTERVAL N
faisaient un full scan car ml_detected_anomalies avait ORDER BY (src_ip) sans
partition ni index temporel.

Changements :
- 06_ml_tables.sql :
  * ml_detected_anomalies : PARTITION BY toYYYYMMDD(detected_at)
    → élagage de partitions journalières sur toutes les requêtes temporelles
  * INDEX idx_detected_at (minmax) → skip des granules hors plage
  * INDEX idx_threat_level set(8) → skip pour countIf(threat_level = ...)
  * INDEX idx_bot_name bloom_filter → skip pour bot_name != ''
  * ttl_only_drop_parts = 1 → TTL par suppression de partition entière
  * ml_all_scores : même traitement (PARTITION BY + 2 indexes)

- 04_mv_http_logs.sql :
  * http_logs : INDEX idx_src_ip bloom_filter(0.01)
    → les requêtes WHERE src_ip = X (analysis.py, variability.py) sautent
    ~90% des granules sans scanner toute la plage temporelle
  * INDEX idx_ja4 bloom_filter(0.01) → idem pour filtres JA4

- 05_aggregation_tables.sql :
  * agg_host_ip_ja4_1h : PROJECTION proj_by_ip ORDER BY (src_ip, window_start, ...)
    → investigation_summary.py et rotation.py (WHERE src_ip = X) utilisent
    automatiquement la projection au lieu de scanner tous les window_start

- 10_perf_indexes.sql (nouveau) :
  * Migration ALTER TABLE pour instances existantes
  * ADD INDEX + MATERIALIZE INDEX pour les 4 tables
  * ADD PROJECTION + MATERIALIZE PROJECTION pour agg_host_ip_ja4_1h
  * Note : PARTITION BY sur table existante nécessite recréation (documenté)

9f3e0621e5 feat: split ClickHouse into dual configurable databases (ja4_logs / ja4_processing) 
Architecture:
- ja4_logs: raw log ingestion (http_logs_raw, http_logs, mv_http_logs)
- ja4_processing: analytics, aggregation, ML, dictionaries, audit

Configuration (env vars):
- CLICKHOUSE_DB_LOGS (default: ja4_logs)
- CLICKHOUSE_DB_PROCESSING (default: ja4_processing)

Changes:
- SQL migrations (10 files): all mabase_prod refs → ja4_logs or ja4_processing
  with correct cross-database references (MVs, views, dicts)
- deploy_schema.sh: substitutes DB names from env vars at deploy time
- Python shared settings: added CLICKHOUSE_DB_LOGS + CLICKHOUSE_DB_PROCESSING
- Dashboard routes (19 files): replaced ~80 hardcoded mabase_prod refs
  with settings.CLICKHOUSE_DB_LOGS / settings.CLICKHOUSE_DB_PROCESSING
- Bot-detector: DB → CLICKHOUSE_DB_PROCESSING, fetch_rules.py configurable
- Correlator: DSN example updated to ja4_logs
- Docker-compose + .env files: new env vars with defaults
- All documentation updated (14 markdown files)

All tests pass: sentinel 10/10, correlator 67.1%, bot-detector 11, dashboard 20, ja4_common 18

d469e39da7 feat: ja4-platform monorepo — 5 services unified, tests & RPM builds standardized 
Services:
- ja4sentinel: TLS/JA4 fingerprint capture daemon (Go, libpcap)
- logcorrelator: JA4 log correlation engine (Go, ClickHouse)
- mod_reqin_log: Apache module (C, JSON request logging)
- bot_detector: ML bot detection pipeline (Python)
- dashboard: FastAPI/Streamlit analytics UI (Python)

Shared libraries:
- shared/go/ja4common: logger, config, shutdown, ipfilter (Go module)
- shared/python/ja4_common: ClickHouseClient, ClickHouseSettings (Python package)
- shared/clickhouse/: canonical SQL migrations (10 files)

Build & packaging:
- Unified 3-stage Dockerfile.package for Go RPMs (el8/el9/el10)
- go.work workspace linking sentinel, correlator, ja4common
- Makefile with test-all, build-all, rpm-* targets

Fixes applied:
- go.work: 1.21 → 1.24.6 (required by sentinel)
- correlator Dockerfiles: golang:1.21 → golang:1.24
- replace directives in go.mod for ja4common local path
- pyproject.toml: setuptools.backends → setuptools.build_meta
- Removed static libpcap linking (unavailable on Rocky 9)
- Fixed data races in output/writers_test.go (sync.Mutex + atomic.Int32)
- Rewrote corrupted test files (logger_test.go × 2)

Test coverage:
- correlator: 67.1% total (unixsocket 80.5%, config 91.7%, app 83.3%, multi 87.7%, stdout 100%)
- sentinel: all 10 packages pass (api, capture, config, fingerprint, ipfilter, logging, output, tlsparse)

Documentation:
- README.md + docs/ (architecture, development, 5 services, shared libs, DB schema & migrations)
