+# Data Model: Frontend Navigation Redesign
+
+## Plugin Configuration
+
+The `PluginConfig` model is extended to support backend-driven navigation.
+
+```python
+class PluginConfig(BaseModel):
+    """Pydantic model for plugin configuration."""
+    id: str = Field(..., description="Unique identifier for the plugin")
+    name: str = Field(..., description="Human-readable name for the plugin")
+    description: str = Field(..., description="Brief description of what the plugin does")
+    version: str = Field(..., description="Version of the plugin")
+    ui_route: Optional[str] = Field(None, description="Frontend route for the plugin UI")
+    input_schema: Dict[str, Any] = Field(..., description="JSON schema for input parameters", alias="schema")
+```
+
+### ui_route
+
+- **Type**: `Optional[str]`
+- **Description**: Specifies the client-side route (URL path) where the plugin's custom UI is hosted.
+- **Behavior**:
+  - If `None` (default): The dashboard will open the plugin using the generic `DynamicForm` modal.
+  - If set (e.g., `"/tools/mapper"`): The dashboard will navigate (`goto`) to this route when the plugin card is clicked.
+
+## Backup Management (New)
+
+### Backup Types
+
+```typescript
+// frontend/src/types/backup.ts
+
+export interface BackupFile {
+    name: string;        // e.g., "prod-dashboard-export-2024.zip"
+    path: string;        // Relative path in storage
+    size: number;        // Bytes
+    created_at: string;  // ISO Date
+    category: 'backups'; // Fixed category
+    mime_type?: string;
+}
+
+export interface BackupState {
+    isLoading: boolean;
+    files: BackupFile[];
+    error: string | null;
+    selectedBackup: BackupFile | null;
+}
