+"""P3 — Compliance-Advisor-Proof: obligation-basierte Antwort aus der Registry (NICHT RAG-Text,
+KEIN LLM). Demonstriert den besseren Antworttyp: PFLICHT (LEGAL_MINIMUM + Rechtsgrundlage +
+Applicability) / BEST PRACTICE (guidance_basis) / NACHWEISE (evidence_facets + member controls)
++ Beziehungen. Deterministisch + zitierfähig — das ist der Produktnutzen der Registry.
