-# DigitalData.TaskFlow.Domain
-
-Dieses Projekt bildet den fachlichen Kern von `DigitalData.TaskFlow`.
-
-## Zweck
-
-Die Domain-Schicht enthaelt ausschließlich fachliche Modelle und Begriffe. Hier wird beschrieben, **was** das System fachlich darstellt, nicht **wie** Daten gelesen/geschrieben werden.
-
-## Aktueller Inhalt
-
-- `Common/`
-  - `ApiEnvelope<T>`: Standard-Response-Huelle mit `Meta` und `Data`.
-  - `MetaEntry`: Einzelner Meta-Eintrag (`Code`, `Message`).
-- `Enums/`
-  - `MetaCode`: Fachliche Status-Codes (z. B. `Ok`, `NoAccess`, `AlreadyClosed`).
-- `Workflows/`
-  - Modelle fuer den Endpoint `GET /workflows/{wisagid}`.
-  - Enthalten Quellblock-Struktur (`SourceBlock`, `FerdinandSourceBlock`, `ContractsSourceBlock`) und Untermodelle (`ProfileItem`, `WorkflowListingItem`, `ApprovalItem`, `DocumentReferenceItem`, `ClosingMethodItem`, `RejectionReasonItem`).
-- `Closing/`
-  - Modelle fuer den Endpoint `POST /workflows/{wisagid}/{source}/{processid}/closing`.
-  - `CloseWorkflowDecision` (Eingabe), `CloseWorkflowResult` (Ergebnis).
-- `Documents/`
-  - `DocumentBinaryResult` fuer den Endpoint `GET /documents/{id}`.
-
-## Architektur-Regeln
-
-- Keine EF-Core-, HTTP-, SQL- oder Infrastruktur-Abhaengigkeiten.
-- Keine Controller- oder Middleware-Logik.
-- Modelle bleiben in PascalCase; technische DB-Namensabweichungen werden spaeter in Infrastructure gemappt.
-
-## Warum diese Schicht wichtig ist
-
-Die Domain stellt eine stabile, technologieunabhaengige Sprache bereit. Dadurch koennen API, Application und Infrastructure getrennt entwickelt werden, ohne den fachlichen Vertrag zu verlieren.
