## 🏗️ **Technical Architecture**

### **🔧 Multi-Library Fallback System**
```python
# Intelligent processing with graceful degradation
async def process_legacy_document(file_path: str, format_hint: str = None):
    # 1. Auto-detect format using magic bytes + extension
    detected_format = await detect_legacy_format(file_path)
    
    # 2. Get prioritized library chain for format
    processing_chain = get_processing_chain(detected_format)
    
    # 3. Attempt extraction with fallbacks
    for method in processing_chain:
        try:
            result = await extract_with_method(method, file_path)
            return enhance_with_ai_processing(result)
        except Exception:
            continue
    
    # 4. Last resort: binary analysis + ML inference
    return await emergency_extraction(file_path)
```
