+  ## Bulk Resolve with Highest Progress Strategy
+  
+    Resolves multiple sync conflicts using the "highest_progress" strategy, which keeps the reading progress with the highest percentage read.
+  
+    **Method:** POST
+  
+    **Endpoint:** /api/conflicts/bulk-resolve
+  
+    **Authentication:** Bearer token
+  
+    **Request Body:**
+    - `conflict_ids` (array): Array of conflict UUIDs to resolve
+    - `strategy` (string): Must be "highest_progress"
+  
+    **Response:**
+    - `results` (array): Results for each conflict resolution
+    - `total` (number): Total number of conflicts processed
+    - `success` (number): Number of successfully resolved conflicts
