Tests for document import added

- Add new "alle-kommentare" (all comments) view for staff users only
  - Allows staff to view and manage all user comments across the system
  - Grouped by document with user information displayed
  - Staff can delete any comment via the dedicated delete button
  - Restricts access via user_passes_test decorator

- Create all_comments.html template
  - Based on user_comments template with added username field
  - Shows comment author, creation time, and edit time
  - Provides delete functionality for comment management

- Update navigation menu
  - Add "Alle Kommentare" link in user dropdown menu
  - Link only visible to staff members

- Add URL route for alle-kommentare page
  - Path: /dokumente/alle-kommentare/
  - URL name: all_comments

- Bump application versions
  - Update footer version from 0.965 to 0.966
  - Update K8s deployment version from 0.917 to 0.918
  - ArgoCD deployment already at 0.966

All existing tests pass (148 tests total)

+- **Server**: 192.168.17.199
+- **Path**: /mnt/user/vorgabenui
+- **Access**: ReadWriteMany for multi-pod access
+- **Reclaim Policy**: Retain (data preserved after PVC deletion)
+
+#### `nfs-storageclass.yaml`
+- **Purpose**: StorageClass definition for NFS volumes
+- **Provisioner**: kubernetes.io/no-provisioner (static provisioning)
+- **Volume Expansion**: Enabled for growing storage capacity
+- **Binding Mode**: Immediate (binds PV to PVC as soon as possible)
+
+#### `diagrammer.yaml`
+- **Purpose**: Deployment configuration for the diagram generation service
+- **Function**: Handles diagram creation and caching for the application
+
+## NFS Storage Configuration
+
+### Prerequisites
+1. NFS server must be running at 192.168.17.199
+2. The directory `/mnt/user/vorgabenui` must exist and be exported
+3. Kubernetes nodes must have NFS client utilities installed
+4. For MicroK8s: `microk8s enable nfs`
+
+## MicroK8s Addons Required
+
+### Required Addons
+Enable the following MicroK8s addons before deployment:
+
+```bash
+# Enable storage and NFS support
+sudo microk8s enable storage
+sudo microk8s enable nfs
+
+# Enable ingress for external access
+sudo microk8s enable ingress
+
+# Enable DNS for service discovery
+sudo microk8s enable dns
+
+# Optional: Enable metrics for monitoring
+sudo microk8s enable metrics-server
+```
+
+### Addon Descriptions
+
+#### `storage`
+- **Purpose**: Provides default storage class for persistent volumes
+- **Required for**: Basic PVC functionality
+- **Note**: Works alongside our custom NFS storage class
+
+#### `nfs`
+- **Purpose**: Installs NFS client utilities on all MicroK8s nodes
+- **Required for**: Mounting NFS volumes in pods
+- **Components**: Installs `nfs-common` package with mount helpers
+
+#### `ingress`
+- **Purpose**: Provides Ingress controller for external HTTP/HTTPS access
+- **Required for**: `ingress.yaml` to function properly
+- **Implementation**: Uses NGINX Ingress Controller
+
+#### `dns`
+- **Purpose**: Provides DNS service for service discovery within cluster
+- **Required for**: Inter-service communication
+- **Note**: Usually enabled by default in MicroK8s
+
+#### `metrics-server` (Optional)
+- **Purpose**: Enables resource usage monitoring
+- **Required for**: `kubectl top` commands and HPA (Horizontal Pod Autoscaling)
+- **Recommended for**: Production monitoring
+
+### Addon Verification
+After enabling addons, verify they are running:
+
+```bash
+# Check addon status
+microk8s status
+
+# Check pods in kube-system namespace
+microk8s kubectl get pods -n kube-system
+
+# Check storage classes
+microk8s kubectl get storageclass
+
+# Check ingress controller
+microk8s kubectl get pods -n ingress
+```
+
+### Troubleshooting Addons
+
+#### NFS Addon Issues
+```bash
+# Check if NFS utilities are installed
+which mount.nfs
+
+# Manually install if addon fails
+sudo apt update && sudo apt install nfs-common
+
+# Restart MicroK8s after manual installation
+sudo microk8s restart
+```
+
+#### Ingress Issues
+```bash
+# Check ingress controller pods
+microk8s kubectl get pods -n ingress
+
+# Check ingress services
+microk8s kubectl get svc -n ingress
+
+# Test ingress connectivity
+curl -k https://your-domain.com
+```
+
+#### Storage Issues
+```bash
+# List available storage classes
+microk8s kubectl get storageclass
+
+# Check default storage class
+microk8s kubectl get storageclass -o yaml
+```
+
+### Storage Architecture
+- **Storage Class**: `nfs` - Static provisioning for NFS shares
+- **Persistent Volume**: Pre-provisioned PV pointing to NFS server
+- **Persistent Volume Claim**: Claims the NFS storage for application use
+- **Access Mode**: ReadWriteMany allows multiple pods to access the same data
+
+### NFS Server Setup
+On the NFS server (192.168.17.199), ensure the following:
+
+```bash
+# Create the shared directory
+sudo mkdir -p /mnt/user/vorgabenui
+sudo chmod 755 /mnt/user/vorgabenui
+
+# Add to /etc/exports
+echo "/mnt/user/vorgabenui *(rw,sync,no_subtree_check,no_root_squash)" | sudo tee -a /etc/exports
+
+# Export the directory
+sudo exportfs -a
+sudo systemctl restart nfs-kernel-server
+```
+
+## Deployment Order
+
+1. **StorageClass** (`nfs-storageclass.yaml`) - Defines NFS storage class
+2. **PersistentVolume** (`nfs-pv.yaml`) - Creates the NFS volume
+3. **PersistentVolumeClaim** (`001_pvc.yaml`) - Claims storage for application
+4. **Application Deployments** (`deployment.yaml`, `diagrammer.yaml`) - Deploy application services
+5. **Ingress** (`ingress.yaml`) - Configure external access
+
+## Configuration Notes
+
+### Namespace
+All resources are deployed to the `vorgabenui` namespace.
+
+### Storage Sizing
+- Current allocation: 2Gi
+- Volume expansion is enabled through the StorageClass
+- Monitor usage and adjust PVC size as needed
+
+### Access Control
+- NFS export uses `no_root_squash` for container root access
+- Ensure proper network security between Kubernetes nodes and NFS server
+- Consider implementing network policies for additional security
+
+## Troubleshooting
+
+### Common Issues
+
+#### Mount Failures
+- **Error**: "bad option; for several filesystems you might need a /sbin/mount.<type> helper program"
+- **Solution**: Install NFS client utilities or enable NFS addon in MicroK8s
+
+#### Permission Issues
+- **Error**: Permission denied when accessing mounted volume
+- **Solution**: Check NFS export permissions and ensure `no_root_squash` is set
+
+#### Network Connectivity
+- **Error**: Connection timeout to NFS server
+- **Solution**: Verify network connectivity and firewall rules between nodes and NFS server
+
+### Debug Commands
+```bash
+# Check PVC status
+kubectl get pvc -n vorgabenui
+
+# Check PV status
+kubectl get pv
+
+# Describe PVC for detailed information
+kubectl describe pvc django-data-pvc -n vorgabenui
+
+# Check pod mount status
+kubectl describe pod <pod-name> -n vorgabenui
+```
+
+## Maintenance
+
+### Backup Strategy
+- The NFS server should have regular backups of `/mnt/user/vorgabenui`
+- Consider snapshot capabilities if using enterprise NFS solutions
+
+### Monitoring
+- Monitor NFS server performance and connectivity
+- Track storage usage and plan capacity upgrades
+- Monitor pod restarts related to storage issues
+
+### Updates
+- When updating storage configuration, update PV first, then PVC
+- Test changes in non-production environment first
+- Ensure backward compatibility when modifying NFS exports

+# Dokumenten-Import: Anleitung
+
+Diese Anleitung beschreibt, wie Dokumente und Vorgaben mittels des `import-document` Management Commands in die VorgabenUI importiert werden können.
+
+## Übersicht
+
+Der `import-document` Command ermöglicht es, strukturierte Textdateien zu importieren, die Dokumente mit Einleitung, Geltungsbereich und Vorgaben enthalten. Das Format ist speziell für die einfache Erfassung und Pflege von IT-Sicherheitsstandards konzipiert.
+
+## Grundlegende Verwendung
+
+### Minimaler Aufruf
+
+```bash
+python manage.py import-document <dateipfad> \
+  --nummer <dokumentnummer> \
+  --name "<dokumentname>" \
+  --dokumententyp "<typ>"
+```
+
+### Beispiel
+
+```bash
+python manage.py import-document Documentation/import\ formats/r009.txt \
+  --nummer "R0009" \
+  --name "Serversysteme" \
+  --dokumententyp "Standard IT-Sicherheit"
+```
+
+## Parameter
+
+### Pflichtparameter
+
+| Parameter | Beschreibung | Beispiel |
+|-----------|--------------|----------|
+| `file_path` | Pfad zur Importdatei | `Documentation/import formats/r009.txt` |
+| `--nummer` | Dokumentnummer (eindeutig) | `R0009`, `R0066` |
+| `--name` | Dokumentname | `"Logging"`, `"Serversysteme"` |
+| `--dokumententyp` | Dokumententyp (muss bereits existieren) | `"Standard IT-Sicherheit"` |
+
+### Optionale Parameter
+
+| Parameter | Beschreibung | Verwendung |
+|-----------|--------------|------------|
+| `--gueltigkeit_von` | Startdatum der Gültigkeit | `--gueltigkeit_von 2024-01-01` |
+| `--gueltigkeit_bis` | Enddatum der Gültigkeit | `--gueltigkeit_bis 2025-12-31` |
+| `--dry-run` | Testlauf ohne Datenbankänderungen | `--dry-run` |
+| `--verbose` | Ausführliche Ausgabe (mit `--dry-run`) | `--dry-run --verbose` |
+| `--purge` | Löscht bestehende Einleitung/Geltungsbereich/Vorgaben vor Import | `--purge` |
+
+### Dry-Run Modus
+
+Der Dry-Run Modus ist besonders nützlich zum Testen:
+
+```bash
+python manage.py import-document r009.txt \
+  --nummer "R0009" \
+  --name "Serversysteme" \
+  --dokumententyp "Standard IT-Sicherheit" \
+  --dry-run --verbose
+```
+
+Dies zeigt an, was importiert würde, ohne die Datenbank zu ändern.
+
+### Purge Modus
+
+**Achtung:** Der Purge-Modus löscht alle bestehenden Vorgaben des Dokuments!
+
+```bash
+python manage.py import-document r009.txt \
+  --nummer "R0009" \
+  --name "Serversysteme" \
+  --dokumententyp "Standard IT-Sicherheit" \
+  --purge
+```
+
+Nutzen Sie `--dry-run --purge` zuerst, um zu sehen, was gelöscht würde.

+
+## Tipps und Best Practices
+
+### 1. Dry-Run vor Import
+
+Führen Sie immer zuerst einen Dry-Run durch:
+
+```bash
+python manage.py import-document datei.txt \
+  --nummer "R0XXX" \
+  --name "Test" \
+  --dokumententyp "Standard IT-Sicherheit" \
+  --dry-run --verbose
+```
+
+### 2. Themen vorab erstellen
+
+Stellen Sie sicher, dass alle verwendeten Themen in der Datenbank existieren:
+
+```python
+python manage.py shell
+>>> from dokumente.models import Thema
+>>> Thema.objects.get_or_create(name="Organisation")
+>>> Thema.objects.get_or_create(name="Technik")
+>>> Thema.objects.get_or_create(name="Informationen")
+```
+
+### 3. Dokumententyp vorab erstellen
+
+Der Dokumententyp muss existieren:
+
+```python
+python manage.py shell
+>>> from dokumente.models import Dokumententyp
+>>> Dokumententyp.objects.get_or_create(
+...     name="Standard IT-Sicherheit",
+...     defaults={"verantwortliche_ve": "SR-SUR-SEC"}
+... )
+```
+
+### 4. Abschnitttypen prüfen
+
+Folgende Abschnitttypen müssen in der Datenbank existieren:
+- `text`
+- `liste geordnet`
+- `liste ungeordnet`
+- `code`
+- `diagramm`
+
+Prüfen Sie diese in der Autorenumgebung unter "Abschnitttypen".
+
+### 5. UTF-8 Kodierung
+
+Stellen Sie sicher, dass Ihre Importdatei UTF-8 kodiert ist, besonders bei Umlauten (ä, ö, ü) und Sonderzeichen.
+
+### 6. Versionierung mit Purge
+
+Beim Re-Import mit `--purge`:
+
+```bash
+# 1. Backup erstellen
+python manage.py dumpdata dokumente.Dokument dokumente.Vorgabe > backup.json
+
+# 2. Import mit Purge
+python manage.py import-document datei.txt \
+  --nummer "R0009" \
+  --name "Serversysteme" \
+  --dokumententyp "Standard IT-Sicherheit" \
+  --purge
+```
+
+### 7. Mehrzeilige Inhalte
+
+Mehrzeiliger Text wird automatisch erkannt:
+
+```
+>>>Langtext
+>>>Text
+Dies ist Zeile 1.
+Dies ist Zeile 2.
+
+Dies ist ein neuer Absatz.
+```
+
+### 8. Leerzeilen
+
+Leerzeilen innerhalb eines Abschnitts werden beibehalten. Eine Leerzeile nach einem `>>>`-Trenner wird ignoriert.
+
+## Fehlerbehebung
+
+### "Dokumententyp does not exist"
+
+Der angegebene Dokumententyp existiert nicht in der Datenbank.
+
+**Lösung:** Erstellen Sie den Dokumententyp in der Autorenumgebung oder per Shell.
+
+### "Thema not found, skipping Vorgabe"
+
+Das in der Vorgabe verwendete Thema existiert nicht.
+
+**Lösung:** Erstellen Sie das Thema in der Autorenumgebung oder passen Sie die Importdatei an.
+
+### "AbschnittTyp not found"
+
+Ein verwendeter Abschnitttyp existiert nicht.
+
+**Lösung:**
+- Prüfen Sie die Schreibweise (Gross-/Kleinschreibung wird normalisiert)
+- Erstellen Sie den Abschnitttyp in der Autorenumgebung
+- Standardtypen: `text`, `liste geordnet`, `liste ungeordnet`
+
+### Vorgabe wird nicht importiert
+
+Prüfen Sie:
+- Ist `>>>Nummer` gesetzt?
+- Ist `>>>Titel` gesetzt?
+- Existiert das Thema?
+
+Verwenden Sie `--dry-run --verbose` für detaillierte Informationen.

+# Diagramme in VorgabenUI
+
+Diese Anleitung beschreibt, wie Diagramme in Textabschnitten verwendet werden können. VorgabenUI nutzt [Kroki](https://kroki.io/) zur Generierung von Diagrammen aus Textbeschreibungen.
+
+## Übersicht
+
+Der Abschnitttyp **"diagramm"** ermöglicht es, verschiedene Diagrammtypen direkt in Vorgaben, Einleitungen und Geltungsbereichen einzubinden. Die Diagramme werden aus Textbeschreibungen automatisch als SVG-Grafiken generiert und gecacht.
+
+## Grundlegende Verwendung
+
+### Format
+
+```
+[Diagrammtyp]
+option: [HTML-Attribute] (optional)
+[Diagramm-Code]
+```
+
+**Zeile 1:** Diagrammtyp (z.B. `plantuml`, `mermaid`, `graphviz`)
+**Zeile 2 (optional):** `option:` gefolgt von HTML-Attributen für die Bildgrösse
+**Zeile 3+:** Der eigentliche Diagramm-Quellcode
+
+### Standard-Einstellungen
+
+Wenn keine `option:`-Zeile angegeben wird, wird das Diagramm mit `width="100%"` dargestellt.
+
+### Grösse anpassen
+
+Um die Grösse des Diagramms anzupassen, verwenden Sie die `option:`-Zeile:
+
+```
+plantuml
+option: width="50%"
+@startuml
+...
+@enduml
+```
+
+Weitere Beispiele für Optionen:
+
+```
+option: width="800px"
+option: width="60%" style="max-width: 600px;"
+option: height="400px"
+option: width="100%" class="img-fluid"
+```
+
+## Unterstützte Diagrammtypen

+### C4 PlantUML: System-Kontext
+
+```
+c4plantuml
+@startuml
+!include https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/master/C4_Context.puml
+
+Person(admin, "Administrator", "BIT System-Administrator")
+System(vorgaben, "VorgabenUI", "IT-Sicherheits-Vorgaben Portal")
+System_Ext(ldap, "LDAP", "Authentifizierung")
+
+Rel(admin, vorgaben, "Verwaltet Vorgaben")
+Rel(vorgaben, ldap, "Authentifiziert über")
+@enduml
+```
+
+**Verwendung:** Software-Architektur nach C4-Modell
+
+## Best Practices
+
+### 1. Diagramm-Grösse anpassen
+
+Verwenden Sie die `option:`-Zeile, um die Grösse für bessere Lesbarkeit anzupassen:
+
+```
+plantuml
+option: width="60%"
+...
+```
+
+Für sehr detaillierte Diagramme:
+```
+plantuml
+option: width="100%" style="max-width: 1200px;"
+...
+```
+
+### 2. Einfachheit bevorzugen
+
+Halten Sie Diagramme einfach und fokussiert. Zu komplexe Diagramme sind schwer zu lesen.
+
+**Gut:**
+```
+mermaid
+flowchart LR
+    A[Start] --> B{Prüfung}
+    B -->|OK| C[Weiter]
+    B -->|Fehler| D[Abbruch]
+```
+
+**Zu komplex:** Vermeiden Sie Diagramme mit mehr als 15-20 Elementen.
+
+### 3. Konsistente Stil-Wahl
+
+Verwenden Sie für ähnliche Konzepte den gleichen Diagrammtyp:
+- **Prozesse:** Mermaid Flowchart oder PlantUML Activity
+- **Kommunikation:** Mermaid/PlantUML Sequence
+- **Architektur:** PlantUML Component oder C4
+- **Netzwerke:** NwDiag oder GraphViz
+
+### 4. Beschriftungen auf Deutsch
+
+Verwenden Sie deutsche Beschriftungen für bessere Verständlichkeit:
+
+```
+mermaid
+flowchart TD
+    Start[Anfrage empfangen] --> Prüfung{Berechtigung?}
+    Prüfung -->|Ja| Zugriff[Zugriff gewähren]
+    Prüfung -->|Nein| Ablehnung[Zugriff verweigern]
+```
+
+### 5. Farben sparsam einsetzen
+
+Nutzen Sie Farben zur Hervorhebung wichtiger Elemente:
+
+```
+graphviz
+digraph {
+    node [shape=box];
+
+    Kritisch [style=filled, fillcolor=red, fontcolor=white];
+    Wichtig [style=filled, fillcolor=orange];
+    Normal [style=filled, fillcolor=lightgreen];
+
+    Kritisch -> Wichtig -> Normal;
+}
+```
+
+### 6. Lesbarkeit testen
+
+Nach dem Speichern prüfen, ob das Diagramm in der Webansicht gut lesbar ist. Bei Bedarf:
+- Grösse anpassen (`option: width="..."`)
+- Diagramm vereinfachen
+- Anderen Diagrammtyp wählen
+
+## Fehlerbehandlung
+
+### Diagramm wird nicht angezeigt
+
+**Mögliche Ursachen:**
+
+1. **Syntaxfehler im Diagramm-Code**
+   - Prüfen Sie die Syntax gemäss Dokumentation des Diagrammtyps
+   - Testen Sie den Code auf https://kroki.io/
+
+2. **Falscher Diagrammtyp**
+   - Erste Zeile muss genau dem Kroki-Typ entsprechen
+   - Beispiel: `plantuml` (nicht `PlantUML` oder `plant-uml`)
+
+3. **Kroki-Server nicht erreichbar**
+   - Bei Fehlermeldung "Error generating diagram" Server prüfen
+
+### Fehlersuche
+
+1. **Code auf kroki.io testen:**
+   ```
+   https://kroki.io/
+   ```
+   Geben Sie dort den Code ein und testen Sie die Generierung.
+
+2. **Diagramm-Cache leeren:**
+   ```bash
+   python manage.py clear_diagram_cache
+   ```
+
+3. **Logs prüfen:**
+   Fehler werden im Application-Log ausgegeben.
+
+## Häufig verwendete Diagramm-Szenarien
+
+### IT-Sicherheit: Bedrohungsmodell
+
+```
+mermaid
+flowchart TB
+    Asset[Schützenswertes Asset]
+    Threat[Bedrohung]
+    Vuln[Schwachstelle]
+    Control[Sicherheitsmassnahme]
+
+    Threat -->|nutzt aus| Vuln
+    Vuln -->|betrifft| Asset
+    Control -->|schliesst| Vuln
+    Control -->|schützt| Asset
+```
+
+### Netzwerk-Segmentierung
+
+```
+nwdiag
+nwdiag {
+    network internet {
+        address = "Internet";
+        internet [shape = cloud];
+    }
+    network dmz {
+        address = "DMZ (192.168.1.0/24)";
+        fw [address = "192.168.1.1"];
+        web [address = "192.168.1.10"];
+    }
+    network internal {
+        address = "Intern (10.0.0.0/8)";
+        fw [address = "10.0.0.1"];
+        app [address = "10.0.1.10"];
+        db [address = "10.0.2.10"];
+    }
+
+    internet -- fw;
+}
+```
+
+### Patch-Management Prozess

+**Zweck**: Speichert detaillierte Beschreibungen und Informationen zu einer Rolle.
+
+**Wichtige Felder**:
+- `abschnitt` (ForeignKey → Rolle, on_delete=CASCADE): Referenz zur Rolle
+- Erbt von `Textabschnitt`:
+  - `abschnitttyp` (ForeignKey → AbschnittTyp, optional)
+  - `inhalt` (TextField, blank=True, null=True)
+  - `order` (PositiveIntegerField, default=0)
+
+**Meta**:
+- `verbose_name = "Rollenbeschreibungs-Abschnitt"`
+- `verbose_name_plural = "Rollenbeschreibung"`
+
+---
+
+## Allgemeine Hinweise zur Modellverwaltung
+
+### Primärschlüssel-Strategie
+- Viele Modelle verwenden CharField-basierte Primärschlüssel (`name`, `nummer`, `stichwort`)
+- Dies ermöglicht direkte Verwendung von Strings als Identifikatoren
+- Vorteil: Lesbarkeit; Nachteil: Umbenennungen sind kritisch
+
+### On-Delete-Strategien
+- **PROTECT**: Verwendet für wichtige Beziehungen (z. B. Dokumententyp, Thema, AbschnittTyp)
+  - Verhindert versehentliches Löschen von Daten, auf die verwiesen wird
+- **CASCADE**: Verwendet für Unterkomponenten (z. B. Vorgabe → Dokument)
+  - Löscht abhängige Datensätze automatisch
+- **SET_NULL**: Nur bei optionalen Referenzen (z. B. Oberreferenz in Referenz-Tree)
+
+### Validierungsmechanismen
+- **Vorgabe.clean()**: Validiert Gültigkeitszeiträume
+- **Vorgabe.find_conflicts()**: Prüft zeitliche Überschneidungen
+- Wird von Django-Admin automatisch aufgerufen vor dem Speichern
+
+### MPTT (Modified Preorder Tree Traversal)
+- Verwendet in `Referenz` für hierarchische Strukturen
+- Ermöglicht effiziente Abfragen von Vorfahren und Nachkommen
+- Zusätzliche Datenbank-Felder für Tree-Management (automatisch verwaltet)
+
+### Textabschnitt-Vererbung
+- Mehrere Modelle erben von `Textabschnitt`
+- Wird verwendet für Lang-/Kurztexte, Erklärungen, Beschreibungen
+- `order`-Feld ermöglicht Sortierung mehrerer Abschnitte
+
+### Datumsverwaltung
+- `gueltigkeit_von`: Immer erforderlich für Vorgaben
+- `gueltigkeit_bis`: Optional; `None` bedeutet unbegrenzte Gültigkeit
+- `_date_ranges_intersect()` prüft korrekt auf Überschneidungen mit None-Werten
+
+### Many-to-Many-Beziehungen
+- Vielfach verwendet für flexible Zuordnungen (Autoren, Stichworte, Rollen, Referenzen)
+- `related_name`-Attribute ermöglichen rückwärts Zugriff
+- Beispiel: `dokument.vorgaben.all()`, `person.verfasste_dokumente.all()`
+
+---
+

+
+Rolle → RollenBeschreibung (1-to-Many)
+
+AbschnittTyp ← Textabschnitt (von verschiedenen Modellen geerbt)
+```
+
+---
+
+## Entwicklungsrichtlinien
+
+- Alle Modelle sollten aussagekräftige `__str__()`-Methoden haben
+- `verbose_name` und `verbose_name_plural` sollten auf Deutsch sein (für Django-Admin)
+- Validierungslogik (z. B. `clean()`) sollte implementiert werden für komplexe Business-Logic
+- Related-Names sollten aussagekräftig und konsistent sein
+- Textinhalte sollten die `Textabschnitt`-Basisklasse erben
+- Datumsverwaltung: Immer auf None-Werte bei `gueltigkeit_bis` achten, wenn Vorgaben noch aktiv sind.

+
+## Changelog
+- Zweck: Änderungsverzeichnis-Eintrag für ein Dokument.
+- Wichtige Felder:
+  - `dokument` (FK → Dokument, related_name='changelog')
+  - `autoren` (M2M → Person)

+
+Hinweise zur Pflege
+- Wichtige Relationen nutzen häufig on_delete=PROTECT, um versehentliche Löschungen zu vermeiden.
+- Viele Modelle haben CharField-Primärschlüssel (z. B. `nummer`, `name`).
+- Validierungslogik für zeitliche Konflikte ist in Vorgabe implementiert (clean / find_conflicts).
+- Textabschnitt-Modelle erben Verhalten aus `abschnitte.models.Textabschnitt` — dort sind Anzeige- und Inhaltsregeln definiert.

+6. **Integration**: Cross-app functionality and data flow
+7. **Security**: 
+   - XSS prevention through HTML sanitization in content rendering
+   - XSS attack prevention in comment system (script tags, javascript: protocol, event handlers)
+   - Input validation and sanitization
+   - Authorization checks (staff vs. regular users)
+   - Security headers (Content-Security-Policy, X-Content-Type-Options)
+8. **Comment Functionality**:
+   - CRUD operations (Create, Read, Delete)
+   - User permissions and ownership
+   - HTML escaping and line break preservation
+   - Multiple XSS attack vector prevention
+
+## Running the Tests
+

+```bash
+python manage.py test
+```
+
+To run tests for a specific app:
+```bash
+python manage.py test app_name
+```
+
+To run with verbose output:
+```bash
+python manage.py test --verbosity=2
+```
+
+All tests are currently passing and provide comprehensive coverage of the application's functionality.

+# Project Context
+
+## Purpose
+This is a Django-based document management system for regulatory documents (Dokumente) and their provisions (Vorgaben). It manages validity periods, conflicts between overlapping provisions, references, keywords, and roles. The system supports importing documents, checking for compliance, and maintaining changelogs.
+
+## Tech Stack
+- Python 3.x
+- Django 5.2.5
+- SQLite (development), PostgreSQL (production)
+- Django MPTT for tree structures
+- Django Nested Admin for inline editing
+- Kubernetes for deployment
+- ArgoCD for continuous deployment
+- Traefik for ingress
+- Gunicorn for WSGI server
+
+## Project Conventions
+
+### Code Style
+- Language: German for user-facing strings and model names, English for code comments and internal naming
+- Imports: Standard library first, then Django, then third-party, then local apps
+- Model naming: German nouns (Dokument, Vorgabe, Person)
+- Field naming: German for field names, English Django conventions
+- Class naming: PascalCase for models, snake_case for functions/variables
+- All models have __str__ methods returning meaningful German strings
+- Use verbose_name and verbose_name_plural in Meta classes (German)
+
+### Architecture Patterns
+- Django apps: abschnitte, dokumente, referenzen, rollen, stichworte, pages
+- MPTT for hierarchical text sections
+- Foreign keys with on_delete=models.PROTECT for important relationships
+- Many-to-many with descriptive related_name
+- Proxy models for different views (e.g., VorgabenTable)
+- Management commands for data operations
+
+### Testing Strategy
+- Django test framework
+- Test class names in English, methods in English
+- Comprehensive model tests
+- Test both success and error cases
+- Run with `python manage.py test`
+
+### Git Workflow
+- Standard Git workflow
+- Commits in English
+- Use Gitea workflows for CI/CD
+
+## Domain Context
+The system manages regulatory documents with numbered provisions that have validity dates. Provisions can conflict if they have overlapping date ranges for the same document, theme, and number. The system includes sanity checks for conflicts, diagram caching for visualization, and JSON export functionality.
+
+## Important Constraints
+- German language for all user interfaces and data
+- Strict validation of date ranges to prevent overlapping provisions
+- Documents have types, authors, reviewers, and validity periods
+- Provisions linked to themes, references, keywords, and relevant roles
+- Active/inactive status for documents
+
+## External Dependencies
+- Django ecosystem: MPTT, nested-admin, revproxy
+- Kubernetes cluster for deployment
+- ArgoCD for GitOps
+- Traefik for load balancing
+- External diagram services (diagramm_proxy)

+
+Schutzmechanismen für die Webfonts 'Frutiger'
+
+Die Schweizerische Bundeskanzlei hat die Webfonts für die Schrift Frutiger für die Internetauftritte der ganzen Bundesverwaltung lizenziert. Hierbei musste die folgende Vertragsbedingung akzeptiert werden:
+
+________________________________
+5. Schutz der Schriften-Software
+
+Die Bestellering und ggf. der Betreiber eines Webfont-Hosting Service sind dafür verantwortlich, dass die Schriften-Software nur hinsichtlich der lizenzierten Websites verwendet werden und nicht durch andere Websites benutzt oder von dort darauf verwiesen wird. Dies beinhaltet unter anderem die Einrichtung von hinreichenden Schutzmassnahmen, die die Verwendung der und/oder den Zugriff auf die Schriften-Software und/oder abgeleiteten Werke beschränken, beispielweise, indem die Nutzung von EOT-Schriften-Software auf die lizenzierten Websites beschränkt wird (Domain-Bindung) oder JavaScript  oder andere Zugriffskontrollmechanismen den Verweise auf die Schriften-Software von nicht lizenzierten Quellen beschränken. Eine Schutzmassnahme, die den vom Browser gelieferten Referrer prüft, ist ebenfalls eine ausreichende Schutzmassnahme.
+Die Verletzung dieser Pflicht stellt eine wesentliche Vertagsverletzung dar, welche die Lieferantin zur ausserordentlichen Kündigung berechtigt, wenn der Verletzung von der Bestellerin nicht innerhalb von vierzehn (14) Tagen nach der schriftlichen Mitteilung über die Verletzung abgeholfen wird.
+_________________________________
+
+
+Im Rahmen der Vertragsverhandlungen wurden die Auflagen vom Lizenzgeber wie folgt erläutert:
+
+   Technisch kann man natürlich alle diese Schutzmaßnahmen auf die eine oder andere Weise umgehen.
+Bisher ging es uns hauptsächlich darum, den direkten Download der Font-Dateien zu verhindern bzw. zu erschweren. Das muss natürlich server-seitig passieren.
+
+   Hier ein Auszug aus einer E-Mail, die ich an einen Kunden gesendet habe:
+
+   Man kann das Herunterladen per Link auf jeden Fall durch HTTP referrer checking erschweren. D.h. ein Web Server liefert einen Web Font nur aus, wenn der vom anfragenden Browser mitgeschickte Referrer eine erlaubte URL ist.
+
+   Im u.a. Fall würde der WebFont also nur ausgeliefert, wenn er von einer HTML-Seite / CSS auf www.xxx.com verlinkt wird (dann ist der im Browser gesetzte Referrer www.xxx.com). Ko-piere ich den Link auf den WebFont heraus und rufe ihn direkt auf (der Browser sendet keinen Referrer) oder integriere den Link in einer anderen Webite (der Referrer wä-re www.anderewebsite.de), antwortet der Server mit einem 403/Forbidden Fehler.
+
+   Referrer checking lässt sich natürlich umgehen. Das nennt sich dann Referrer Spoofing. Dafür muss man aber entsprechendes Fachwissen haben bzw. entsprechende Tools kennen und nutzen.
+
+   So würde man Referrer checking bspw. beim Apache Web Server konfigurieren:
+http://wiki.apache.org/httpd/DisableImageHotLinking
+
+   Ich würde eine solche "Hot-Link-Protection" als wirksame Schutzmaßnahme bezeichnen, die zwischen gültigen (korrekter Referrer) und ungültigen (Referrer ist eine andere Website oder leer) Anfragen unterscheidet.
+
+
+Um die vertraglich eingegangen Auflagen einzuhalten legt die Bundeskanzlei mit der Abgabe der Schriften-Software fest:
+
+• Die Webverantwortlichen der Departemente und der Bundeskanzlei sorgen dafür, dass die technischen Auflagen zum Schutz der Schriften-Software eingehalten werden, indem Sie die bundesinterne Betreiber (IKT-Leistungserbringer) über die zu implementierenden Schutzmechanismen informieren und eine Bestätigung verlangen, dass diese durchgeführt werden. Ist der Betreiber bundesextern, so wird die Auflage unter den besonderen Vertragbedigungen entsprechend vereinbart.
+• Die Webverantwortlichen der Departemente verpflichten sich im Fall der Verletzung der Pflicht das Notwendige zu unternehmen, damit die Pflicht innerhalb von 14 Tagen eingehalten wird und die ausserordentlich Kündigung abgewendet werden kann.

+# Frutiger
+The Confederation Web Guidelines should come with Frutiger as the main font. But due to [licence](LICENSE) restrictions, the font files cannot be distributed on this repository.
+A copy can be obtained on the [federal chancellery intranet]( 
+https://intranet.bk.admin.ch/bk-intra/de/home/dl-koordination-bund/kommunikation/webforum-bund/Downloads.html) or directly requested per email: [webforum@bk.admin.ch](mailto:webforum@bk.admin.ch). The font files then have to be copied into the `src/assets/fonts` directory.
+ 
+According to the Frutiger [licence](LICENSE), the font files have to be protected. Each project should ensure that only allowed domains have access the font. The proposed solution is to check that the REFERER http header is present and contains the project's domain.
