feat: implement thesis §5 advanced detection techniques as ClickHouse MVs
New aggregation tables + materialized views:
- agg_path_sequences_1h + MV (§5.1 Path Sequence Entropy)
- agg_request_timing_1h + MV (§5.3 Request Cadence Fingerprint)
- agg_ip_behavior_1h + MV (§5.5 JA4 Drift + §5.8 Cross-Domain)
- agg_resource_cascade_1h + MV (§5.4 Resource Dependency Tree)
New analytical views:
- view_thesis_features_1h: unified view exposing all computable features
(path_transition_entropy, cadence_cv, burst_ratio, pause_ratio,
ja4_drift_ratio, host_diversity, host_sweep_speed,
host_coverage_uniformity)
- view_resource_cascade_1h: root_to_first_asset_delay, asset_load_stddev
Documented future techniques (not feasible as MV):
- §5.2 Bipartite Fleet Graph (needs Python networkx)
- §5.6 DNS Shadow Analysis (needs sentinel UDP/53 extension)
- §5.7 Compression Ratio Invariant (needs mod_reqin_log extension)
Updated: deploy_schema.sh, verify_mvs.py (sections 8-10)

perf(clickhouse): P10 — créer les 4 vues métier manquantes + corriger préfixes DB
Bug de production : view_form_bruteforce_detected, view_host_ip_ja4_rotation,
view_dashboard_entities, view_dashboard_user_agents étaient référencées dans
13 endpoints du dashboard mais n'existaient nulle part dans le schéma.
Tous ces endpoints retournaient HTTP 500 en production.
shared/clickhouse/11_views.sql (nouveau) :
view_form_bruteforce_detected
Source : agg_host_ip_ja4_1h (24h)
Logique : GROUP BY (src_ip, host) HAVING count_post >= 10
Usage : bruteforce.py (3 endpoints), investigation_summary.py
view_host_ip_ja4_rotation
Source : agg_host_ip_ja4_1h (24h)
Logique : uniqExact(ja4) par src_ip, HAVING >= 2 (rotation de fingerprint)
Usage : rotation.py (3 endpoints), investigation_summary.py
view_dashboard_entities
Source : http_logs (7 jours), UNION ALL 5 branches (ip/ja4/country/asn/host)
Colonnes : entity_type, entity_value, src_ip, ja4, host, log_date,
client_headers Array(String), asns Array, countries Array,
user_agents Array
Usage : entities.py (5 endpoints), clustering.py
view_dashboard_user_agents
Source : http_logs (7 jours), GROUP BY (src_ip, ja4, hour)
Colonnes : src_ip, ja4, hour, log_date, user_agents Array(String), requests
Usage : variability.py (4 endpoints), fingerprints.py (5 endpoints)
attributes.py (2 endpoints)
deploy_schema.sh : ajout de 10_perf_indexes.sql et 11_views.sql dans la liste
routes/variability.py + fingerprints.py :
Correction de 9 requêtes utilisant view_dashboard_user_agents sans préfixe
de base de données → remplacé par {settings.CLICKHOUSE_DB_PROCESSING}.view_*

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
