2bfb4b7282 perf(dashboard): P2 — remplacer replaceRegexpAll dans les WHERE par IPv4MappedToIPv6 
Problème : 8 clauses WHERE appliquaient une fonction sur la colonne src_ip :
  WHERE replaceRegexpAll(toString(src_ip), '^::ffff:', '') = %(ip)s
→ ClickHouse ne peut pas utiliser l'index de tri ou les skipping indexes
  quand une fonction est appliquée à la colonne filtrée.

Fix : transformer l'INPUT (le paramètre) plutôt que la colonne :
  WHERE src_ip = IPv4MappedToIPv6(toIPv4(%(ip)s))
→ src_ip reste intact → ClickHouse utilise les indexes (P1) et la
  projection proj_by_ip (P1) pour ces requêtes.

Fichiers modifiés :
  investigation_summary.py — 6 WHERE (ml_detected_anomalies, agg_host_ip_ja4_1h,
                              view_form_bruteforce_detected, view_host_ip_ja4_rotation,
                              view_ip_recurrence)
  ml_features.py           — 1 WHERE (view_ai_features_1h)
  rotation.py              — 1 WHERE (agg_host_ip_ja4_1h)

Note : les 27 autres occurrences de replaceRegexpAll dans les SELECT sont des
transformations d'affichage (IPv6→IPv4 pour l'UI) et ne bloquent pas les indexes.

b6391afbeb refactor: replace hardcoded mabase_prod DB prefix with configurable settings 
Replace all hardcoded 'mabase_prod.' table prefixes in dashboard route
SQL queries with configurable database names from settings:

- http_logs, http_logs_raw → settings.CLICKHOUSE_DB_LOGS
- All other tables → settings.CLICKHOUSE_DB_PROCESSING

Also qualify previously unqualified table references (bare FROM/JOIN
table_name) with the appropriate database prefix for consistency.

Each route file now imports 'from ..config import settings' and uses
f-strings with {settings.CLICKHOUSE_DB_PROCESSING} or
{settings.CLICKHOUSE_DB_LOGS} for database-qualified table names.

Files updated: analysis, attributes, audit, botnets, bruteforce,
clustering, detections, entities, fingerprints, header_fingerprint,
heatmap, incidents, investigation_summary, metrics, ml_features,
rotation, search, tcp_spoofing, variability (19 files).

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)
