+# Normative Verbindlichkeit — Dreistufenmodell
+
+## Uebersicht
+
+Nicht jede Quelle, aus der Controls abgeleitet werden, hat die gleiche rechtliche
+Verbindlichkeit. Ein Control, das aus einem EU-Gesetz stammt, hat ein anderes
+Gewicht als eines aus einem freiwilligen Framework.
+
+Das Dreistufenmodell klassifiziert jede Quell-Regulierung und leitet daraus die
+**effektive normative Staerke** der daraus erzeugten Obligations ab.
+
+## Die drei Stufen
+
+```mermaid

+    subgraph "Stufe 1 — GESETZ (law)"

+    C1 --> C2 --> C3 --> C4
+```
+
+### Stufe 1: Gesetz (law)
+
+| Eigenschaft | Beschreibung |
+|---|---|
+| **Verbindlichkeit** | Rechtlich bindend, Bussgeld bei Verstoss |
+| **normative_strength** | Bleibt wie im Gesetzestext: `must`, `should` oder `may` |
+| **Beispiele** | DSGVO (EU) 2016/679, NIS2-Richtlinie, KI-Verordnung, CRA, BDSG |
+| **Warum relevant** | "Sie MUESSEN angemessene technische Massnahmen ergreifen" (Art. 32 DSGVO) |
+
+!!! warning "Wichtig"
+    Gesetze formulieren Pflichten **abstrakt**. Art. 32 DSGVO sagt:
+    "dem Stand der Technik entsprechende Massnahmen" — aber NICHT
+    "verwende AES-256". Das WAS ist Pflicht, das WIE bleibt offen.
+
+### Stufe 2: Leitlinie (guideline)
+
+| Eigenschaft | Beschreibung |
+|---|---|
+| **Verbindlichkeit** | Nicht direkt bindend, aber Beweislastumkehr |
+| **normative_strength** | Maximal `should` — auch wenn die Leitlinie intern "must" schreibt |
+| **Beispiele** | EDPB-Leitlinien, BSI Technische Richtlinien, WP29-Dokumente |
+| **Warum relevant** | "Daten at rest muessen verschluesselt werden" (BSI-TR) → `should` |
+
+!!! info "Beweislastumkehr"
+    Wenn eine Aufsichtsbehoerde fragt "Warum verschluesselt ihr nicht?",
+    muss die Firma begruenden, warum sie von der Leitlinie abweicht.
+    Die Firma muss aber nicht genau so verschluesseln wie die BSI vorschlaegt.
+
+### Stufe 3: Framework (framework)
+
+| Eigenschaft | Beschreibung |
+|---|---|
+| **Verbindlichkeit** | Freiwillig, nicht rechtsverbindlich |
+| **normative_strength** | Maximal `can` — unabhaengig von interner Sprache |
+| **Beispiele** | ENISA CCM, NIST CSF, OWASP Top 10, OECD KI-Empfehlung |
+| **Warum relevant** | "Organizations SHALL implement..." (ENISA) → `can` fuer den Anwender |
+
+!!! tip "Stand der Technik"
+    NIS2 Art. 21 verweist auf ENISA-Leitlinien als Referenz fuer den
+    "Stand der Technik". Das hebt ENISA-Controls faktisch auf Stufe 2 (`should`)
+    — aber nur im Kontext von NIS2-pflichtigen Unternehmen, nicht generell.
+
+## Ableitungskette
+
+Die vollstaendige Kette von der Rechtsquelle zum atomaren Control:
+
+```mermaid
+graph LR
+    R["Regulierung<br/>(DSGVO Art. 32)"] -->|"MUSS"| O["Obligation<br/>(Daten schuetzen)"]
+    O -->|decomposition| RC["Rich Control<br/>(Verschluesselung)"]
+    RC -->|pass0b| AC["Atomares Control<br/>(AES-256 at rest)"]
+
+    R2["Framework<br/>(ENISA CCM)"] -->|"KANN"| AC
+
+    style R fill:#fee2e2,stroke:#dc2626
+    style R2 fill:#dbeafe,stroke:#2563eb
+    style O fill:#fef3c7,stroke:#d97706
+    style RC fill:#e0e7ff,stroke:#4f46e5
+    style AC fill:#d1fae5,stroke:#059669
+```
+
+**Beispiel**: Das atomare Control "AES-256 Verschluesselung at rest"
+
+- Aus DSGVO Art. 32 abgeleitet → Obligation "must secure data" → **MUSS** (die Pflicht zu schuetzen)
+- Aus ENISA CCM konkretisiert → **KANN** (AES-256 ist *eine* moegliche Umsetzung)
+- Resultat: Die Firma MUSS verschluesseln, KANN aber waehlen wie
+
+## Multi-Parent-Links
+
+Ein atomares Control kann aus mehreren Quellen stammen:
+
+| Control | Parent 1 | Parent 2 | Parent 3 | Effektive Staerke |
+|---|---|---|---|---|
+| SEC-042 (Encrypt at rest) | DSGVO Art. 32 (law) | NIS2 Art. 21 (law) | ENISA CCM (framework) | **must** (Gesetz uebertrumpft) |
+| NET-015 (Zero Trust) | NIST SP 800-207 (framework) | CISA (framework) | — | **can** (nur Frameworks) |
+| AUTH-003 (MFA) | DSGVO Art. 32 (law) | BSI-TR (guideline) | OWASP ASVS (framework) | **must** (Gesetz vorhanden) |
+
+**Regel**: Der hoechste source_type bestimmt, ob die normative_strength begrenzt wird.
+Wenn mindestens ein Parent-Link ein Gesetz ist, bleibt die Staerke wie extrahiert.
+
+## Technische Umsetzung
+
+### Klassifikations-Map
+
+Datei: `backend-compliance/compliance/data/source_type_classification.py`
+
+Jeder `source_regulation`-Wert aus `control_parent_links` wird klassifiziert:
+
+```python
+SOURCE_REGULATION_CLASSIFICATION = {
+    "DSGVO (EU) 2016/679": "law",
+    "EDPB Leitlinien 01/2020 (Datentransfers)": "guideline",
+    "NIST Cybersecurity Framework 2.0": "framework",
+    # ... 55+ Eintraege
+}
+```
+
+### Backfill-Endpoint
+
+```
+POST /api/compliance/v1/canonical/controls/backfill-normative-strength?dry_run=true
+```
+
+Ablauf:
+
+1. Alle aktiven `obligation_candidates` laden
+2. Fuer jede Obligation den Parent-Control finden
+3. Ueber `control_parent_links` die source_regulations ermitteln
+4. Hoechsten source_type bestimmen
+5. `normative_strength` begrenzen falls noetig
+6. Bei `dry_run=false`: Aenderungen in die DB schreiben
+
+### Cap-Funktion
+
+```python
+def cap_normative_strength(original: str, source_type: str) -> str:
+    """
+    cap_normative_strength("must", "framework") → "can"
+    cap_normative_strength("should", "law")     → "should"
+    cap_normative_strength("must", "guideline") → "should"
+    """
+```
+
+## Frontend-Anzeige
+
+In der Control-Detail-Ansicht werden Obligations mit farbcodierten Badges angezeigt:
+
+| normative_strength | Badge | Farbe | Bedeutung |
+|---|---|---|---|
+| `must` | **MUSS** | Rot | Gesetzliche Pflicht |
+| `should` | **SOLL** | Gelb/Amber | Empfohlen, Begruendungspflicht bei Abweichung |
+| `can` / `may` | **KANN** | Gruen | Freiwillige Best Practice |
+
+## Haeufige Fragen
+
+### Warum steht bei einem ENISA-Control "MUSS"?
+
+**Vor dem Backfill**: Das System uebernahm die Sprache des Quelldokuments 1:1.
+ENISA schreibt intern "shall/must" weil es innerhalb seines Frameworks
+verbindlich formuliert. Fuer den Anwender ist das ENISA-Dokument aber nicht
+rechtsverbindlich.
+
+**Nach dem Backfill**: ENISA-Controls zeigen maximal "KANN", es sei denn
+ein Gesetz (z.B. NIS2) referenziert dasselbe Control — dann gilt die
+gesetzliche Verbindlichkeit.
+
+### Was bedeutet "Stand der Technik"?
+
+NIS2 und DSGVO verweisen auf den "Stand der Technik", ohne ihn zu definieren.
+In der Praxis werden ENISA- und BSI-Dokumente als Referenz herangezogen.
+Das macht ihre Empfehlungen relevant ("SOLL"), aber nicht zu Gesetzen ("MUSS").
+
+### Wie gehe ich mit unbekannten Quellen um?
+
+Neue Regulierungen muessen in der `SOURCE_REGULATION_CLASSIFICATION` Map
+eingetragen werden. Der Fallback fuer unbekannte Quellen ist `framework`
+(konservativstes Ergebnis — geringste Verbindlichkeit zugewiesen).
