 **Umsetzung 1–2:** Skript `local/scripts/_flatten_i18n_dicts.py` (mehrsprachige Dicts → deutscher String / `json.dumps`). Anschliessend manuell: `mainSystem.py` AICore-`providerLabels`-Fallback; `portTypes.PortField.description` auf `str`; `_deriveFormPayloadSchema` / `_deriveTransformSchema`; `entryPoints._normalize_title` liefert `str`. **`Role.description`** bleibt `TextMultilingual`: `coerce_text_multilingual()` in `datamodelUtils.py` wandelt Template-Strings/Dicts; Bootstrap- und Feature-`Role(...)`-Aufrufe nutzen `coerce_text_multilingual(...)`.
 
+**Umsetzung 3:** Flatten-Skript (Phase 3) für alle 12 Datamodel-Dateien. Neues Regex-Pattern `en, fr, de` für Trustee-Reihenfolge. Manuell: `SubscriptionPlan.title` und `.description` von `Dict[str, str]` auf `str` geändert; Downstream-Fixes in `routeSubscription.py`, `mainServiceSubscription.py`, `stripeBootstrap.py` (`.get("de")` → direkter String-Zugriff). `_registerDatamodelOptionLabels()` in `i18nRegistry.py` war bereits kompatibel (nutzt `_extractDe` das `str` und `dict` handelt).

+**Umsetzung 4:** `PHASE4` im Flatten-Skript; `frontendTypes.py`: `CUSTOM_TYPE_DESCRIPTIONS`, `getCustomTypeDescription`, `registerCustomType` entfernt (ungenutzt). **Umsetzung 5:** `Store.tsx` / `storeApi` / `routeStore`: Label & Description als deutsche i18n-Keys + `t()`; `FEATURE_REGISTRY` und `MandateFeature.label` als `string`; Hilfsfunktion `labelAsI18nKey()`; Admin-Seiten mit `t(labelAsI18nKey(...))`; `routeAdminFeatures.get_my_feature_instances`: `_featureLabelPlain()` liefert String-Labels statt Dict-Fallback.

 ## Problemstellung
 
 Trotz Phase 1–7 der i18n-Unification existieren noch **~640+ statische mehrsprachige Dicts** (`{"en":…, "de":…, "fr":…}`) im Gateway und **~60+ Stellen** im Frontend. Diese Dicts:
