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.

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

b1218a2367 fix(ja4ebpf): fix TLS capture, SYN offsets, TCP option parsing
- Increase MAX_TLS_PAYLOAD from 512 to 2048 bytes to capture full
  TLS ClientHellos (modern browsers/curl send 1000-1543 byte ClientHellos)
- Fix ParseClientHello to tolerate XDP-truncated payloads: clamp
  recordLength and chLen to available data instead of returning error
- Fix cipher suites, compression, extensions truncation to use clamping
- Fix consumeSynEvents struct field offsets: dst_ip (4 bytes at offset 4)
  was not accounted for, causing all L3/L4 metadata to be read from
  wrong positions (TTL was actually dst_ip[0], windowSize was dst_port, etc.)
- Add parseTCPOptions() to extract MSS and Window Scale from raw TCP options
  (C code sets defaults of mss=0, window_scale=0xFF, expects Go to parse)
- Fix consumeAcceptEvents: skip zero-IP events to avoid phantom sessions
- Fix consumeSSLEvents: filter zero-IP/port events when proc fallback fails
- Add missing consumeHTTPPlainEvents goroutine (was defined but never called)
- Fix race condition: SYN consumer sets Correlated=true if TLS already present
- Update tls_hello_event struct offsets in Go consumer (payload_len now at
  offset 2054, was 518, due to payload array growing from 512 to 2048 bytes)
- Remove debug logging from consumers and GC

E2E verified: HTTP plain (port 80) and HTTPS (port 443) both produce
fully correlated sessions in ClickHouse with correct:
  - ip_meta_ttl=64, ip_meta_df=true, ip_meta_id
  - tcp_meta_window_size=64240, tcp_meta_window_scale=10, tcp_meta_mss=1460
  - ja4=t13i3010_1d37bd780c83_95d2a80e6515
  - tls_alpn=http/1.1
  - method=GET, path=/, header_order_signature=Host;User-Agent;Accept
  - correlated=1

f85a10b012 feat: pipeline L7 HTTP complet + infrastructure tests VM
Correctifs pipeline L7 (uprobe SSL_read) :
- uprobe_ssl.c : ssl_set_fd ne retourne plus tôt quand fd_conn_map est
  vide (accept4 non disponible en Docker). Sauvegarde ssl_ptr→{fd,0,0}
  pour permettre le fallback /proc côté Go.
- main.go : consumeSSLEvents reécrit avec routeur magic-bytes complet :
  * HTTP/2 preface → extraction SETTINGS + conversion correlation.HTTP2Settings
  * HTTP/1.x requête → method, path, query, headers, header_order_sig
  * HTTP/1.x réponse → status_code
  * Fallback /proc/<tgid>/fd/<fd> quand src_ip=0 (accept4 absent)
- writer/clickhouse.go : export header_order_signature ajouté

Nouveaux packages :
- internal/parser/http1.go : parseur HTTP/1.x (IsHTTP1Request,
  ParseHTTP1Request, IsHTTP1Response, ParseHTTP1Response)
- internal/parser/http1_test.go : 11 tests unitaires (28 total passent)
- internal/procutil/proc_lookup.go : résolution fd→IP via /proc avec cache
  TTL 5s (FDCache). Supporte /proc/PID/net/tcp et tcp6, IPv4-mappé IPv6.

Infrastructure tests VM (tests/vm/) :
- Vagrantfile : VM Rocky Linux 9 KVM, 4 CPU / 4 GB RAM
- provision.sh : installation toolchain eBPF + Go + Docker + nginx
- run-tests-vm.sh : suite de test complète dans la VM (L3/L4+TLS+L7)
- README.md : guide d'installation et d'utilisation
- Makefile : cibles vm-up, vm-down, vm-ssh, test-vm-nginx, test-vm-all,
  vm-rebuild-ja4ebpf

Corrections stack Docker :
- Dockerfiles nginx/apache/nginx-varnish/hitch-varnish : suppression des
  références à shared/go/ja4common/ (répertoire supprimé)
- clickhouse-init.sh : restauré depuis git, seed anubis_ua_rules obsolète
  supprimé (table REGEXP_TREE supprimée du schéma)
- traffic-gen : ajout HTTP/1.0 (http.client) et HTTP/2 (httpx)
- verify_db.py : script de vérification 35 checks (L3/L4/TLS/L7/corrélation)
- run-stack-tests.sh : phase 6 verify_db ajoutée

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

7eb3ad21fd feat(dashboard): afficher SETTINGS H2 individuels dans la table mismatch
- /api/browser-signatures : top_mismatches inclut désormais les 7 colonnes
  SETTINGS individuelles (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)
- stats : ajout sessions_with_priority (countIf h2_priority_present > 0)
- browsers.html : colonne SETTINGS compact dans la table suspects
  (format '3:100, 4:65536, 2:0' — IDs Akamai avec valeurs non-nulles)
- Compteur pseudo-priority utilise la vraie valeur sessions_with_priority
  au lieu d'afficher '—'

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.

d098de1a66 fix(bot-detector): neutralize H2 dimensions behind proxy (X-Forwarded-For)
When has_xff=1, the H2 connection is terminated by the reverse proxy/CDN,
so client H2 fingerprints are lost. Previously only D1 (h2_settings) was
neutralized; D2 (window_update), D3 (pseudo_order), and D4 (priority)
still penalized proxied traffic — a real Chrome behind Cloudflare scored
0.0 on 3 dimensions (45% of total weight).

Now all 4 H2 dimensions return 0.5 (neutral) when has_xff>0, and
non-browser H2 detection is also disabled behind proxies.

Tests: 10/10 passed including 3 new XFF-specific cases.

e52cdcc01f feat(bot-detector): Browser Signature Detection engine (parallel mode)
Étape A — browser_signatures.py
  Données pures : BROWSER_SIGNATURES (Chrome/Firefox/Safari), NON_BROWSER_SIGNATURES
  (curl/httpx/go), BROWSER_THRESHOLDS, DIMENSION_WEIGHTS. Valeurs H2 extraites
  des captures réelles (format Akamai avec virgules, non semicolons).

Étape B — browser_matcher.py
  Moteur vectorisé 7 dimensions (H2 SETTINGS 0.30, WINDOW_UPDATE 0.15,
  pseudo-header order 0.15, H2 PRIORITY 0.10, HTTP headers 0.15, TLS 0.10,
  JA4 dict 0.05). run_browser_matcher(df) ajoute bm_family/bm_score/bm_decision.
  CDN edge case : dimension H2 neutralisée (0.5) si has_xff=1.
  BROWSER_MATCHER_REPLACE=false par défaut (mode DUAL_MODE logging uniquement).

Étape C — 06_browser_signature_detection.sql (migration)
  Crée browser_h2_signatures (table MergeTree avec 12 fingerprints de référence).
  Recrée dict_browser_h2 depuis la table avec champ confidence (remplace CSV).

Étape D — 07_ai_features_view.sql
  +h2_wu_val dans le JOIN http_logs, +h2_window_update_value, +h2_dict_family,
  +h2_dict_confidence, +h2_window_{chrome,firefox,safari,absent},
  +h2_order_{chromesafari,firefox}, +h2_priority_present, +h2_pseudo_ord_raw,
  +tls_h2_family_mismatch (détection incohérence famille JA4 vs famille H2).

Étape E — preprocessing.py + pipeline.py
  preprocessing.py: appelle run_browser_matcher() après compute_browser_axes(),
  ajoute 7 nouvelles features binaires H2 à FEATURES et binary_features.
  pipeline.py: appelle log_dual_mode_comparison() après la classification A9.
  BROWSER_MATCHER_REPLACE=true active le remplacement du bypass.

Étape F — test_browser_matcher.py
  8 tests : Chrome/Firefox/Safari full match, curl rejeté, httpcloak partiel,
  TLS↔H2 mismatch, CDN proxy neutralisation, go net/http rejeté.
  Tous 8 PASSED (+ 36 tests existants inchangés).

79dbb23d6f feat(dashboard): sélecteur de plage temporelle sur /campaigns
Avant : toutes les vues de campagnes étaient fixes à 7 jours.
Après : sélecteur 1j / 7j (défaut) / 14j / 30j / 90j en haut à droite.

- Ajout du paramètre ?days= (1–90, défaut 7) à :
    GET /api/campaigns
    GET /api/campaigns/graph
    GET /api/campaigns/scatter
    GET /api/campaigns/{cid}
- Le sélecteur recharge simultanément les 3 vues (cartes, scatter, graphe)
  et le panneau de détail avec la même fenêtre temporelle
- Le compteur de campagnes indique la plage active : (4 campagnes — 30j)

9548b1782d fix: corriger ORDER BY ml_detected_anomalies dans le schéma de base
CH 24.8 refuse MODIFY ORDER BY sur des colonnes existantes (erreur BAD_ARGUMENTS 36).
La migration 01 ne pouvait donc pas corriger l'ORDER BY en post-init.

Correctif :
- 06_ml_tables.sql : ORDER BY (src_ip) → ORDER BY (src_ip, ja4, host, model_name)
  + TTL 30j → 7j (cohérent avec l'architecture documentée)
- 01_ttl_adjustments.sql : supprime le MODIFY ORDER BY impossible, conserve
  uniquement les MODIFY TTL (valides pour les déploiements existants)

Résultat : make init-stack sans aucun ⚠ ni ✗

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

2f2c5e03bb fix(sql): contournement bug scope ClickHouse 24.8 dans view_ai_features_1h
- Restructure 07_ai_features_view.sql : single anonymous inner subquery
  avec aliases explicites sur toutes les colonnes (a.xxx AS xxx, h.xxx AS xxx,
  h2.xxx AS xxx) pour résoudre l'ambiguïté PARTITION BY src_ip dans l'outer SELECT
- Supprime les CTEs multiples (h2_agg, enriched) qui déclenchaient le bug
- Fix migration 04_http2_fields.sql : ordre DEFAULT avant CODEC (syntax ClickHouse)
- make init-stack : 0 erreur sur 13 fichiers SQL

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

8ca4a1e849 feat(mod_reqin_log): fingerprinting HTTP/2 passif (Akamai format)
Ajoute un filtre d'entrée de connexion (AP_FTYPE_CONNECTION, APR_HOOK_LAST)
qui s'insère entre mod_ssl et mod_http2 pour lire de manière non-destructive
le preface HTTP/2 (RFC 9113 §3.4) et en extraire :

- h2_fingerprint    : fingerprint Akamai complet
                      ex. '1:65536,2:0,4:6291456,6:262144|15663105|0|m,a,s,p'
- h2_settings_fp    : entrées SETTINGS brutes  (ex. '1:65536,4:6291456')
- h2_window_update  : incrément WINDOW_UPDATE  (ex. '15663105')
- h2_pseudo_order   : ordre des pseudo-headers (ex. 'm,a,s,p' Chrome,
                                                     'm,p,s,a' Firefox)

Technique : lecture spéculative AP_MODE_SPECULATIVE (non-destructive)
de 512 octets — la donnée reste disponible pour mod_http2. Le filtre
se retire de la chaîne après la première invocation.

Stockage dans c->notes (H2_NOTE_*) puis émission JSON dans log_request().
ClickHouse : 4 nouvelles colonnes dans http_logs + JSONExtract dans mv_http_logs.
Migration pour déploiements existants : 04_http2_fields.sql.
14 tests unitaires (cmocka) couvrent Chrome/Firefox/HTTP1/troncature/HPACK.

14db3d9040 refactor: suppression dépendance User-Agent de la détection navigateur
Changements SQL :
- modern_browser_score : sec-ch-ua→100, Sec-Fetch→70 (plus de UA fallback)
- Ajout has_sec_ch_ua (UInt8) dans agg_header_fingerprint_1h et ml_all_scores
- mss_mobile_mismatch utilise has_sec_ch_ua au lieu de modern_browser_score

9ea36ad22e feat(scripts): complete stack init + prod data import with date shift
Schema cleanup:
- Remove anubis_ua_rules table stub from 03_anubis_tables.sql
- Remove anubis_ua_rules from bot-detector deploy_schema.sql
- Remove UA seed step from clickhouse-init.sh (no more REGEXP_TREE dependency)
- Drop dict_anubis_ua, dict_anubis_country, anubis_ua_rules, anubis_country_rules

New scripts:
- scripts/init-stack.sh: comprehensive ClickHouse init (13 SQL files + migrations
  + validation + cleanup of obsolete tables). Supports --reset, --import-prod.
- scripts/import-prod-data.sh: imports pre-exported prod data (Native format)
  with dynamic date shift (max(time) → now). Supports --shift, --no-truncate.
- scripts/data/prod-export/: directory for cached Native format exports

Makefile targets: init-stack, import-prod-data, init-and-import

Tested: init-stack.sh passes all 13 SQL + 7 critical tables + 7 dicts
        import-prod-data.sh: 3M rows in ~37s with auto date shift
        Dashboard: 55 routes OK, bot-detector: 36/36 tests pass

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.

- 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)

c994ad4466 fix: XGB label query + SHAP isotree compatibility
XGB: query was selecting features from ml_all_scores which doesn't
store them. Now joins ml_all_scores (labels) with view_ai_features_1h
(features). Dynamically discovers available columns to skip thesis §5
features not present in the view. Returns (model, features) tuple.

SHAP: TreeExplainer doesn't support isotree. Fall back to permutation-
based Explainer(model.decision_function, X_sample) for isotree.

Verified: XGB trained on 50000 labels (18436 positives), triple-voice
ensemble scoring active (EIF+AE+XGB), SHAP silent.

c6666e2bba fix: isotree score convention — proper sklearn calibration
isotree decision_function returns [0,1] (higher=anomalous, 0.5=boundary).
The entire pipeline (normalize_scores, score_to_threat_level,
compute_adaptive_threshold) expects sklearn convention (negative=anomalous).

Previous fix (-raw_scores) negated all values, making everything
below -0.30 → all CRITICAL. New fix: 0.5 - isotree_score maps
correctly to sklearn's convention:
  isotree 0.80 → -0.30 (CRITICAL)
  isotree 0.65 → -0.15 (HIGH)
  isotree 0.55 → -0.05 (MEDIUM)
  isotree 0.50 →  0.00 (boundary)

Verified: 27,952 LEGITIMATE_BROWSER + 15,843 HIGH + 15,059 MEDIUM
Tests: 36/36 pass.

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)
