P81 — tests/fixtures/golden_truth/vw_de.json:
GT-Fixture mit must_find_cookies (47 VW-Cookies) + expected_vendors
(Google, Adobe, Trade Desk, ...). Basis fuer kuenftige Regression-Tests.

P85 — banner_screenshot_block.py + consent_scanner.py + main.py:
consent-tester macht beim Banner-Detect einen base64-PNG-Screenshot
(< 1.5MB). Backend rendert ihn als <img src="data:..."> direkt nach
dem GF-1-Pager. Visueller Beweis 'so sah das Banner aus' fuer Dispute
mit Marketing/DSB.

P70 — rag_provenance.py:
classify_finding_provenance() klassifiziert ein Finding als 'rag'
(Norm + Quelle), 'mixed' (Norm ohne Quelle) oder 'heuristic' (eigene
Interpretation). provenance_badge_html() rendert kleine Badges
(✓ RAG / NORM / ⚠ HEURISTIK). Modul ist generisch, kann bei jedem
Finding-Renderer einklinkt werden.

P83 — scripts/check-rebuild-needed.sh:
Prueft ob die im Container deployten BUILD_SHA mit local HEAD
uebereinstimmen. Bei Mismatch exit 1 mit 'REBUILD REQUIRED'-Hinweis.
Verhindert das 'alter Code im Container'-Problem das uns mehrfach
erwischt hat (Frontend-Tabs sichtbar, Backend ohne neuen Service).

TCF-Fix — tcf_vendor_authority.py:
cookie_library hat keinen UNIQUE-Index auf cookie_name → ON CONFLICT
war unmoeglich. Loesung: vor Insert DELETE WHERE source_name='iab_tcf_v2'.
Idempotent. + per-Vendor-Commit damit ein Fail die naechsten nicht blockt.

Drei zusammenhaengende Stufen 'Cookie-Verhalten ist anders als deklariert' —
analog zum VW-Diesel-Skandal-Pattern (Pruefstand vs Realbetrieb).

P103 (Stufe 3) — cookie_value_entropy.py:
Klassifiziert Cookie-Werte als flag/short_id/long_token/uuid/hash/json_blob
via Shannon-Entropy + Regex-Patterns. Wenn ein als 'essential' deklarierter
Cookie einen 64-char-Base64-Wert hat → MEDIUM-Finding 'Defeat-Device-Heuristik'.

P104 (Stufe 4) — cookie_network_tracer.py:
Vergleicht Cookie-Domain mit Site-Hauptdomain + bekannten Tracker-Vendoren
(50 Domains gemapped: doubleclick.net, facebook.com, demdex.net, omtrdc.net,
adsrvr.org, hotjar.com, ...). Wenn ein als 'essential' deklariertes Cookie
von externer Tracker-Domain gesetzt wird → HIGH. Drittland-Cookies werden
als 'DRITTLAND US/CN/...' markiert (Schrems-II-Folge).

P105 (Stufe 5) — tcf_vendor_authority.py:
Ingest-Endpoint POST /api/compliance/agent/admin/tcf-ingest holt die
IAB TCF v2 Global Vendor List (vendor-list.consensu.org/v3) und upserted
sie in cookie_library mit source='iab_tcf_v2'. cross_reference_with_tcf
fuzzy-matched cmp_vendors gegen die TCF-Liste — wenn Vendor in TCF als
Marketing gefuehrt aber Site sagt 'Funktional' → HIGH (externe Authority
widerspricht der Deklaration).

Alle drei rendern eigene Mail-Bloecke im Bereich Cookies (nach
cookie_audit_html, vor library_mismatch_html).
