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.

261205028d fix(dashboard): campaigns scatter chart — show campaigns not IPs
- API /api/campaigns/scatter: aggregate by campaign_id instead of per-IP
  Returns avg_score, avg_velocity, unique_ips, ja4_list, asn_list, country_list
- Template: one bubble per campaign, sized by IP count
- Tooltip: campaign-level info (IPs, score, velocity, ASNs, pays, JA4s)
- Click navigates to campaign detail (not IP detail)
- Updated doc panel text

da1b579d4f fix(dashboard): rename duplicate /api/browsers route to /api/browser-signatures
La route /api/browsers existait déjà (distribution JA4 par famille).
La nouvelle route du browser_matcher était en conflit — FastAPI utilisait
la première définition. Renommage en /api/browser-signatures.

92432085e2 fix(campaigns): fix IP navigation URL encoding
fmtIP() returns an HTML <a> tag string. Using encodeURIComponent(fmtIP(ip))
was URL-encoding the entire HTML markup instead of the raw IP address,
resulting in /ip/%3Ca%20href%3D... navigation.

Fix: extract raw IP (stripping ::ffff: prefix) before building the URL.
Applied to all 3 click handlers in campaigns.html:
- members table row onclick
- scatter chart point click
- force graph node click

a108814a56 feat: roadmap détection bots §2-9 — HTTP/2, cohérence, drift, flotte, Jaccard, ExIFFI, méta-learner, métriques
Étape 2 — Fingerprinting HTTP/2 dans le pipeline ML :
- Ajout du dictionnaire dict_browser_h2 (11 familles de navigateurs) dans 05_aggregation_tables.sql
- Ajout du CTE h2_agg et 4 features HTTP/2 dans 07_ai_features_view.sql :
  h2_settings_known, h2_pseudo_order_match, h2_ja4_coherence, h2_settings_rare
- Calcul du fingerprint_coherence_score (5 axes pondérés) dans la vue
- Ajout du 6e axe axis_h2_coherence dans browser.py (poids rééquilibrés)
- browser_h2.csv : 11 fingerprints Akamai → famille navigateur

Étape 3 — Pré-filtre de cohérence sur la baseline humaine :
- pipeline.py exclut les sessions avec fingerprint_coherence_score < seuil de la baseline d'entraînement
- FINGERPRINT_COHERENCE_THRESHOLD configurable via env (défaut 0.25)
- Log des sessions exclues pour analyse SOC

Étape 4 — Détection de drift améliorée :
- scoring.py : passage de 5 à 9 quantiles (p5…p95)
- Ajout de la divergence KL en complément du test KS
- Détection de drift adversarial (≥80% des features dérivent dans la même direction)
- Split temporel strict pour la validation

Étape 5 — Graphe bipartite JA4×ASN (§5.2) :
- fleet.py : détection de flottes via NetworkX + Louvain (imports optionnels)
- enrich_with_fleet_score() : ajout fleet_score + fleet_campaign_flag au DataFrame
- cycle.py : appel après preprocess_df avec log du nombre de sessions en flotte
- SQL migration 05_fleet_metrics_tables.sql : table fleet_detections (TTL 7j)
- Dashboard : /fleet + /api/fleet (communautés détectées) + template fleet.html

Étape 6 — Cross-domain Jaccard §5.8 :
- 12_thesis_features.sql : CTE jaccard_paths → cross_domain_path_similarity
- Signal : même chemins (/admin, /wp-login) sur plusieurs hosts = scanner

Étape 7 — ExIFFI + erreurs AE par feature :
- scoring.py : compute_exiffi_importance() par permutation, compute_ae_feature_errors()
- pipeline.py : calcul ExIFFI sur X_test, mapping index → dict pour anomalies
- build_reason() enrichi avec exiffi_top quand SHAP inactif

Étape 8 — Méta-learner pour la pondération de l'ensemble :
- scoring.py : classe MetaLearner (LogisticRegression, fallback poids fixes <1000 labels)
- Collecte des labels depuis le cycle courant (known_bots, légitimes, Anubis)
- pipeline.py : remplacement des poids fixes par MetaLearner.predict()

Étape 9 — Métriques de performance et monitoring :
- metrics.py : record_cycle_metrics() — taux anomalie, drift, corrélation, latence
- SQL migration 05_fleet_metrics_tables.sql : table ml_performance_metrics (TTL 90j)
- Dashboard : /health + /api/health + template health.html
- cycle.py : appel record_cycle_metrics en fin de cycle (Complet + Applicatif)

Tests : 36/36 bot-detector tests passent

70188b508c fix(dashboard): eliminate @apply CSS, fix status column, fix click propagation
Playwright testing revealed 3 critical bugs:

1. Tailwind CDN @apply with custom brand-* colors produces empty CSS
   rules, breaking ALL design components (kpi-card, data-table, badges,
   filter-btn, section-card, nav-item). Fix: replace all @apply
   directives with equivalent raw CSS values.

2. Traffic API and IP detail API reference non-existent 'status' column
   in http_logs table → HTTP 500 on /traffic and /ip/{ip}. Fix: remove
   status from SELECT, sort whitelist, filters, and templates.

3. Nested <a> links (fmtJA4, fmtASN, fmtCountry, fmtBotName) inside
   clickable <tr onclick> capture clicks, preventing row navigation to
   /ip/ detail. Fix: add event.stopPropagation() to all formatter links.

Verified with Playwright: 10 pages × 0 JS errors, all tooltips hidden
by default, sidebar toggle works, keyboard shortcuts (Alt+1-9, Alt+B),
classification form saves to DB, campaign detail panel opens on click.

6babc55e3e fix(dashboard): hover infobulles, full-width layout, UX polish
- Fix doc tooltips: split CSS into <style type='text/tailwindcss'> for
  @apply directives + raw CSS for reliable doc panel rendering
- Convert doc panels from click-toggle to hover-based infobulles with
  arrow pointer, fade-in animation, and auto-dismiss on mobile
- Replace '?' icons with 'ⓘ' across all 11 templates (51 tooltips)
- Full-width layout: reduce padding on mobile (px-3), scale up on
  desktop (lg:px-5, xl:px-6) for maximum screen utilization
- Auto-collapse sidebar on narrow screens (<1024px)
- Keyboard shortcuts: Alt+1–9 for page navigation, Alt+B toggle sidebar
- Add LEGITIMATE_BROWSER filter button to detections page
- Sticky header with stronger blur (backdrop-blur-md)
- All 46 routes pass tests

db306fb9da fix: P0 audit bugs — bot-detector + dashboard + SQL
Bot-detector:
- B1.1: campaign_id and raw_anomaly_score now inserted into ml_detected_anomalies
- B1.4/B1.5: log_decision argument order fixed (cycle_id, name)
- B1.7: AE broadcast error — model now returns features list, scoring
  uses model's features instead of current cycle's (prevents dim mismatch)
- B1.8: Anubis ALLOW bots now get bot_name from anubis_bot_name

Dashboard:
- C1.1: XSS in ip_detail.html — {{ ip | tojson }} instead of raw string
- C1.2: Stored XSS via innerHTML — added escapeHtml() helper, all user-facing
  formatters (fmtIP, fmtASN, fmtCountry, fmtJA4, fmtBotName, fmtLabel) sanitized
- C2.1: status filter now correctly filters http_version column
- C2.2: heatmap toDayOfWeek() - 1 for 0-indexed JS days

SQL:
- B1.3: view_ip_recurrence worst_score uses max() not min() (0=normal, 1=anomal)
- B1.6: view_resource_cascade_1h joined into view_thesis_features_1h (§5.4)
