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.

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)
