+- Endpoint: `GET /api/v1/batch/{batch_id}/status`
+
+**10.4 Error Handling with Retry Logic**
+- File: [backend/app/services/background_tasks.py:63](../../../backend/app/services/background_tasks.py#L63)
+- Implemented `execute_with_retry()` method for generic retry logic
+- Implemented `process_single_file_with_retry()` for OCR processing with 3 retry attempts
+- Added `retry_count` field to `OCRFile` model
+- Migration: [backend/alembic/versions/271dc036ea80_add_retry_count_to_files.py](../../../backend/alembic/versions/271dc036ea80_add_retry_count_to_files.py)
+- Configurable retry delay (default: 5 seconds)
+- Error messages include retry attempt information
+
+**10.5 Cleanup Scheduler for Expired Files**
+- File: [backend/app/services/background_tasks.py:189](../../../backend/app/services/background_tasks.py#L189)
+- Implemented `cleanup_expired_files()` method
+- Automatic cleanup of files older than 24 hours
+- Runs every 1 hour (configurable via `cleanup_interval`)
+- Deletes:
+  - Physical files and directories
+  - Database records (results, files, batches)
+- Respects foreign key constraints
+- Started automatically on application startup: [backend/app/main.py:42](../../../backend/app/main.py#L42)
+- Gracefully stopped on shutdown
+
+**10.6 PDF Generation in Background Tasks**
+- File: [backend/app/services/background_tasks.py:226](../../../backend/app/services/background_tasks.py#L226)

+## 🌐 Phase 2: Frontend API Schema Alignment (2025-11-12)
+
+### Issue Summary
+During frontend development, identified 6 critical API mismatches between frontend expectations and backend implementation that blocked upload, processing, and results preview functionality.
+
+### 🐛 API Mismatches Fixed
+
+**1. Upload Response Structure** ⬅️ **FIXED**
+- **Problem**: Backend returned `OCRBatchResponse` with `id` field, frontend expected `{ batch_id, files }`
+- **Solution**: Created `UploadBatchResponse` schema in [backend/app/schemas/ocr.py:91-115](../../../backend/app/schemas/ocr.py#L91-L115)
+- **Impact**: Upload now returns correct structure, fixes "no response after upload" issue
+- **Files Modified**:
+  - `backend/app/schemas/ocr.py` - Added UploadBatchResponse schema
+  - `backend/app/routers/ocr.py:38,72-75` - Updated response_model and return format
+
+**2. Error Field Naming** ⬅️ **FIXED**
+- **Problem**: Frontend read `file.error`, backend had `error_message` field
+- **Solution**: Added Pydantic validation_alias in [backend/app/schemas/ocr.py:21](../../../backend/app/schemas/ocr.py#L21)
+- **Code**: `error: Optional[str] = Field(None, validation_alias='error_message')`
+- **Impact**: Error messages now display correctly in ProcessingPage
+
+**3. Markdown Content Missing** ⬅️ **FIXED**
+- **Problem**: Frontend needed `markdown_content` for preview, only path was provided
+- **Solution**: Added field to OCRResultResponse in [backend/app/schemas/ocr.py:35](../../../backend/app/schemas/ocr.py#L35)
+- **Code**: `markdown_content: Optional[str] = None  # Added for frontend preview`
+- **Impact**: Markdown preview now works in ResultsPage
+
+**4. Export Options Schema Missing** ⬅️ **FIXED**
+- **Problem**: Frontend sent `options` object, backend didn't accept it
+- **Solution**: Created ExportOptions schema in [backend/app/schemas/export.py:10-15](../../../backend/app/schemas/export.py#L10-L15)
+- **Fields**: `confidence_threshold`, `include_metadata`, `filename_pattern`, `css_template`
+- **Impact**: Advanced export options now supported
+
+**5. CSS Template Filename Field** ⬅️ **FIXED**
+- **Problem**: Frontend needed `filename`, backend only had `name` and `description`
+- **Solution**: Added filename field to CSSTemplateResponse in [backend/app/schemas/export.py:82](../../../backend/app/schemas/export.py#L82)
+- **Code**: `filename: str = Field(..., description="Template filename")`
+- **Impact**: CSS template selector now works correctly
+
+**6. OCR Result Detail Structure** ⬅️ **FIXED** (Critical)
+- **Problem**: ResultsPage showed "檢視 Markdown - undefined" because:
+  - Backend returned nested `{ file: {...}, result: {...} }` structure
+  - Frontend expected flat structure with `filename`, `confidence`, `markdown_content` at root
+- **Solution**: Created OCRResultDetailResponse schema in [backend/app/schemas/ocr.py:77-89](../../../backend/app/schemas/ocr.py#L77-L89)
+- **Solution**: Updated endpoint in [backend/app/routers/ocr.py:181-240](../../../backend/app/routers/ocr.py#L181-L240) to:
+  - Read markdown content from filesystem
+  - Build flattened JSON data structure
+  - Return all fields frontend expects at root level
+- **Impact**:
+  - MarkdownPreview now shows correct filename in title
+  - Confidence and processing time display correctly
+  - Markdown content loads and displays properly
+
+### ✅ Frontend Functionality Restored
+
+**Upload Flow**:
+1. ✅ Files upload with progress indication
+2. ✅ Toast notification on success
+3. ✅ Automatic redirect to Processing page
+4. ✅ Batch ID and files stored in Zustand state
+
+**Processing Flow**:
+1. ✅ Batch status polling works
+2. ✅ Progress percentage updates in real-time
+3. ✅ File status badges display correctly (pending/processing/completed/failed)
+4. ✅ Error messages show when files fail
+5. ✅ Automatic redirect to Results when complete
+
+**Results Flow**:
+1. ✅ Batch summary displays (batch ID, completed count)
+2. ✅ Results table shows all files with actions
+3. ✅ Click file to view markdown preview
+4. ✅ Markdown title shows correct filename (not "undefined")
+5. ✅ Confidence and processing time display correctly
+6. ✅ PDF download works
+7. ✅ Export button navigates to export page
+
+### 📝 Additional Frontend Fixes
+
+**1. ResultsPage.tsx** ([frontend/src/pages/ResultsPage.tsx:134-143](../../../frontend/src/pages/ResultsPage.tsx#L134-L143))
+- Added null checks for undefined values:
+  - `(ocrResult.confidence || 0)` - Prevents .toFixed() on undefined
+  - `(ocrResult.processing_time || 0)` - Prevents .toFixed() on undefined
+  - `ocrResult.json_data?.total_text_regions || 0` - Safe optional chaining
+
+**2. ProcessingPage.tsx** (Already functional)
+- Batch ID validation working
+- Status polling implemented correctly
+- Error handling complete
+
+### 🔧 API Endpoints Updated
+
+**Upload Endpoint**:
+```typescript
+POST /api/v1/upload
+Response: { batch_id: number, files: OCRFileResponse[] }
+```
+
+**Batch Status Endpoint**:
+```typescript
+GET /api/v1/batch/{batch_id}/status
+Response: { batch: OCRBatchResponse, files: OCRFileResponse[] }
+```
+
+**OCR Result Endpoint** (New flattened structure):
+```typescript
+GET /api/v1/ocr/result/{file_id}
+Response: {
+  file_id: number
+  filename: string
+  status: string
+  markdown_content: string
+  json_data: {...}
+  confidence: number
+  processing_time: number
+}
+```
+
+### 🎯 Testing Verified
+- ✅ File upload with toast notification
+- ✅ Redirect to processing page
+- ✅ Processing status polling
+- ✅ Completed batch redirect to results
+- ✅ Results table display
+- ✅ Markdown preview with correct filename
+- ✅ Confidence and processing time display
