P1 — Exec-Summary oben im Email-Report (4 KPIs + 2 CTAs, dunkler Gradient)
P3 — no_direct_sales-Flag fuer OEM-Konfigurator-Sites; AGB/Widerruf/AGB als
     "NICHT ANWENDBAR" (grau) statt "NICHT GEFUNDEN" (rot)
P5 — Voll-Audit Unification: alle Findings (MC + Pflichtangaben + Vendor +
     Redundanz) in /data/compliance_audits.db.unified_findings; neuer
     /api/compliance/agent/findings/<id> Endpoint + FindingsTab im Audit-UI
     mit Filter + CSV-Export
P7 — Crawl-Hardening: TDM-Reservation-Check (robots.txt / ai.txt / Header /
     Meta) vor jedem Run mit 24h-Cache; HeadlessChrome-UA (Firma noch nicht
     gegruendet — Switch via BREAKPILOT_BRANDED_UA env); per-Domain
     Rate-Limit 1 req/s + max 2 concurrent
P2 — Cookie-Knowledge-DB additiv erweitert (35 -> 74 Cookies): Adobe, Meta,
     Microsoft, LinkedIn, TikTok, HubSpot, Marketo, Salesforce, Hotjar,
     FullStory, Mouseflow, Intercom, Drift, Zendesk, Cloudflare, Stripe,
     OneTrust/Cookiebot/Usercentrics, Matomo, Pinterest, Snapchat, X/Twitter,

     Optimizely, Datadog; Wire-in in cookie_function_classifier liefert
     compliance_risk-Label (kritisch/hoch/mittel/gering) pro Vendor
A  — k-Anonymitaets-Helper (benchmark_k_anonymity) fuer P6-Vorbereitung
B  — Cross-Tenant-Domain-Assertion im /findings-Endpoint (expected_domain
     Query-Param -> 403 bei Mismatch)
C  — Saving-Scan-Funnel: /api/compliance/agent/saving-scan/start mit
     Validierung + 24h-Rate-Limit pro Domain + Lead-Persistenz in
     saving_scan_leads + Auto-Discovery via _run_compliance_check; 6 Tests
D  — Risk-Badge im Email-Vendor-Row
