c60ce97f23 feat(bot-detector): add dynamic browser profiling engine with HDBSCAN clustering 
Implement offline profile building (profile_builder.py) and real-time
dynamic scoring (browser_matcher_dynamic.py) using HDBSCAN-based browser
fingerprint clustering. Add ClickHouse materialized view (13_h2_profiling.sql)
for h2_profile_stats aggregation. Update thesis and project documentation
to cover the new dynamic profiling architecture.

64dada980f docs: synchronize thesis with codebase — browser_matcher, fleet detection, module counts 
Update THESIS_HTTP_Traffic_Detection.md to reflect actual implementation state:
- Module count: 12 → 14 modules, 2 912 → 3 700 lines
- browser_matcher: [partiel] → [impl.] (all 7 scoring dimensions, Chrome/Firefox/Safari signatures)
- Fleet detection §5.2: HDBSCAN → Louvain with connected components fallback
- §3.9.1 H2 tables: update Firefox/Safari pseudo-header order to real captured values
- §7 conclusion: 96/0/0 features (all implemented, zero partial)

957918c565 fix(ja4ebpf): Rocky Linux RPM builder, remove correlated field, fix thesis 
- Dockerfile.package: migre go-builder de golang:bookworm (Debian) vers
  rockylinux:9, installe Go depuis le tarball officiel, remplace apt par
  dnf (clang llvm libbpf-devel bpftool)

- Suppression du champ 'correlated' de l'agent ja4ebpf : avec eBPF/XDP,
  la corrélation L3/L4↔L7 est toujours implicite par présence des champs.
  Supprimé de : session.go, manager.go, main.go (x5), clickhouse.go

- Thèse (6 corrections listées + cohérence correlated) :
  1. §3.5 + §3.9.1 : SSL_read retourne des octets bruts sans respecter les
     frontières H2 → buffer circulaire de réassemblage en Go userspace
  2. §3.1 : supprimé libpcap + CAP_NET_RAW, remplacé par définition uprobe
  3. §4 + §7 : compte exact 96 features en 8 familles (Famille 1–8),
     supprimé taxonomie F1–F11 obsolète, tous les totaux mis à jour
  4. §2.4 + §8 : remplacé 7 fausses URLs arXiv par [Référence à vérifier]
  5. §4 Famille 2 : ja4_drift_ratio → renvoi à Famille 8 (définition complète)
  6. §6.4 : ajouté limite 'Overhead de l'uprobe SSL_read'
  + §3.6 : supprimé correlated=0/1 du texte architectural

3b047b680a fix(ja4ebpf): split bpf2go generate into Ja4Tc + Ja4Ssl, fix RPM systemd-rpm-macros 
- Use two separate //go:generate directives (Ja4Tc for tc_capture.c, Ja4Ssl
  for uprobe_ssl.c) to avoid duplicate LICENSE symbol and multi-file clang issue
- Update loader.go to hold tcObjs/sslObjs separately with correct field names:
  UprobeSslSetFd, UprobeSslReadEntry, UretprobeSslReadExit,
  KprobeAccept4Entry, KretprobeAccept4Exit
- Add systemd-rpm-macros to all three RPM build stages (el8/el9/el10)
  so that %{_unitdir} macro resolves correctly
- RPMs now build successfully for el8, el9, el10

f704541f83 feat(h2): direct per-parameter SETTINGS comparison in browser_matcher 
- Rewrote _d1_h2_settings() with 3-signal weighted formula:
  direct_score×0.60 + dict_match×0.30 + ja4_coherence×0.10
  when individual SETTINGS cols are available in the DataFrame
- Added _H2_SETTINGS_COLS dict (IDs 1,2,3,4,5,6,8 → column names)
- Fallback to dict_match×0.80 + ja4_coherence×0.20 for backward compat
- Fix view_ai_features_1h: pass 7 individual SETTINGS columns through
  base_data CTE (h2_header_table_size, h2_enable_push,
  h2_max_concurrent_streams, h2_initial_window_size, h2_max_frame_size,
  h2_max_header_list_size, h2_enable_connect_protocol)
- Remove non-existent h2_dict_confidence reference from view SQL
  (dict_browser_h2 only exposes browser_family attribute)
- Add 7 new pytest cases: exact match, one wrong setting, forbidden key
  penalty, unknown fingerprint with correct settings, fallback path,
  CDN proxy neutralisation, full Chrome simulation
- 53/53 bot-detector tests pass
- Update thesis §3.9.2: document direct comparison algorithm + fallback

85d3b95b7b feat: HTTP/2 passive fingerprinting with individual SETTINGS fields 
Complete implementation of HTTP/2 passive fingerprinting per thesis §2.5.3:

mod-reqin-log (C module):
- Replace connection-level filter with ap_hook_process_connection (APR_HOOK_FIRST)
  to capture H2 preface before mod_http2 takes over the connection
- AP_MODE_SPECULATIVE read of 512 bytes from c->input_filters
- Parse SETTINGS, WINDOW_UPDATE, PRIORITY flags, pseudo-header order
- Output individual SETTINGS params as separate JSON fields (IDs 1-6, 8)
- Read H2 notes from c1 (master connection) for mod_http2 secondary conns
- Fix header_order_signature JSON length bug (26→strlen)

ClickHouse schema:
- Add 8 new columns to http_logs: h2_has_priority, h2_header_table_size,
  h2_enable_push, h2_max_concurrent_streams, h2_initial_window_size,
  h2_max_frame_size, h2_max_header_list_size, h2_enable_connect_protocol
- Use Int32/Int64 with DEFAULT -1 to distinguish absent vs zero
- Update mv_http_logs to extract individual fields via JSONHas/JSONExtractInt
- Migration 04_http2_fields.sql updated for existing deployments

Correlator:
- Accept both timestamp_ns and timestamp field names (backward compat)

Integration:
- Enable HTTP/2 in Apache: Protocols h2 http/1.1 in httpd-integration.conf

Validated end-to-end via Playwright: H2 curl traffic → mod-reqin-log →
correlator → ClickHouse with all 12 H2 columns populated correctly.

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

- 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

- 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)
