-      if (onRename) onRename(folder.path, folder.name);
-    };
-  }
-}
-```
-
-**Impact**: Folder dropdown now shows rename option with proper callback
-
----
-
-### ✅ 3. js/api/hfService.js - Fix Cache & Error Handling
-
-**Changes Made**:
-
-#### Change 3.1: Cache TTL Alignment
-```javascript
-// BEFORE
-const CACHE_TTL = 5 * 60 * 1000; // 5 minutes
-
-// AFTER
-const CACHE_TTL = 60 * 1000; // 60 seconds (aligned with backend HF cache)
-```
-
-#### Change 3.2: Enhanced listFiles() Response Validation
-```javascript
-// BEFORE
-if (data && data.success) {
-  if (data.files) { /* process files */ }
-  if (data.folders) { /* process folders */ }
-}
-
-// AFTER
-// Validate response structure
-if (!data || typeof data !== 'object' || data.success !== true) {
-  console.warn('Invalid API response structure:', data);
-  this.cache.set(cacheKey, { data: result, timestamp: Date.now() });
-  return result;
-}
-
-if (Array.isArray(data.files)) {
-  for (const item of data.files) {
-    result.files.push({
-      path: item.path || '',
-      name: item.name || 'unnamed',
-      // ... safe field access with defaults
-    });
-  }
-}
-```
-
-#### Change 3.3: Improved deleteFile Error Handling
-```javascript
-// BEFORE
-async deleteFile(path) {
-  await this.fetchWithRetry(url, { /* ... */ });
-  this.clearCache();
-  return true;
-}
-
-// AFTER
-async deleteFile(path) {
-  const res = await this.fetchWithRetry(url, { /* ... */ });
-  this.clearCache();
-  const data = await res.json();
-  if (!data.success) {
-    throw new Error(data.error || 'Failed to delete file');
-  }
-  return data;
-}
-```
-
-#### Change 3.4: Improved deleteFolder Error Handling
-```javascript
-// Similar to deleteFile—checks success and throws error if false
-```
-
-#### Change 3.5: Improved getHistory Error Handling
-```javascript
-// BEFORE
-async getHistory(path) {
-  const res = await this.fetchWithRetry(url, { /* ... */ });
-  const data = await res.json();
-  return data.success ? data.history : [];
-}
-
-// AFTER
-async getHistory(path) {
-  const res = await this.fetchWithRetry(url, { /* ... */ });
-  const data = await res.json();
-  if (!data || !data.success) {
-    console.warn('Failed to get history:', data?.error || 'Unknown error');
-    return [];
-  }
-  return Array.isArray(data.history) ? data.history : [];
-}
-```
-
-**Impact**: 
-- Cache now reflects backend changes within 60s instead of 5 minutes
-- API responses properly validated before processing
-- Error information properly propagated to UI
-
----
-
-### ✅ 4. server/storage/hf.py - Fix Type Validation & Typo
-
-**Changes Made**:
-
-#### Change 4.1: Add File Data Validation
-```python
-# LOCATION: upload() method, around line 62-70
-
-# BEFORE
-if hasattr(file_obj, 'read'):
-    file_data = file_obj.read()
-else:
-    file_data = file_obj
-
-# AFTER
-if hasattr(file_obj, 'read'):
-    file_data = file_obj.read()
-else:
-    file_data = file_obj
-
-# Validate file_data is bytes
-if not isinstance(file_data, (bytes, bytearray)):
-    raise TypeError(f"Expected bytes, got {type(file_data).__name__}")
-```
-
-#### Change 4.2: Fix Docstring Typo
-```python
-# BEFORE
-def rename(self, user_id: str, old_path: str, new_name: str) -> Dict[str, Any]:
-    """Atomic rename using create_commit with bath moves"""
-
-# AFTER  
-def rename(self, user_id: str, old_path: str, new_name: str) -> Dict[str, Any]:
-    """Atomic rename using create_commit with batch operations"""
-```
-
-**Impact**:
-- Prevents silent failures when malformed file objects are passed
-- Improves code clarity in commit messages
-- Type checking happens early in the request lifecycle
-
----
-
-### ✅ 5. server/routes/api.py - Fix Storage Stats Endpoint
-
-**Changes Made**:
-
-```python
-# BEFORE
-@api_bp.route('/storage-stats', methods=['GET'])
-def storage_stats():
-    """Get storage statistics"""
-    try:
-        user_id = get_user_id_from_request()
-        result = get_storage().get_stats(user_id)
-        return jsonify(result), 200
-    except Exception as e:
-        logger.error(f"Error in storage_stats: {str(e)}")
-        return jsonify({"success": False, "error": str(e)}), 500
-
-# AFTER
-@api_bp.route('/storage-stats', methods=['GET'])
-def storage_stats():
-    """Get storage statistics"""
-    try:
-        user_id = get_user_id_from_request()
-        result = get_storage().get_stats(user_id)
-        
-        # Check success status before responding
-        if not result.get('success'):
-            return jsonify(result), 400
-        
-        return jsonify(result), 200
-    except Exception as e:
-        logger.error(f"Error in storage_stats: {str(e)}")
-        return jsonify({"success": False, "error": str(e)}), 500
-```
-
-**Impact**:
-- Storage stats endpoint now properly reports errors
-- Frontend receives correct HTTP status codes (400 on error, 200 on success)
-- Complies with REST API standards
