🏗️ Enhanced Core Service Architecture

New Core Service Structure

📁 backend/api/content_planning/services/content_strategy/core/
├── 📄 strategy_service.py (ENHANCED - ~500 lines)
│   ├── EnhancedStrategyService class
│   ├── Core strategy creation logic
│   ├── Strategy retrieval and processing
│   ├── Onboarding data integration
│   └── Legacy compatibility methods
├── 📄 field_mappings.py (existing)
├── 📄 constants.py (existing)
└── 📄 __init__.py (updated)

Core Service Enhancements

1. Comprehensive Strategy Creation: Full implementation of strategy creation with all 30+ fields
2. Advanced Strategy Retrieval: Multi-strategy processing with AI integration
3. Onboarding Integration: Complete onboarding data processing and field auto-population
4. Legacy Compatibility: Maintains backward compatibility with existing code
5. Modular Dependencies: Uses extracted utilities and services

🔄 Facade Pattern Implementation

Enhanced Strategy Service as Facade

The main enhanced_strategy_service.py is now a thin facade that:

1. Delegates to Core Service: All core logic delegated to CoreStrategyService
2. Maintains API Compatibility: Preserves existing method signatures
3. Provides Clean Interface: Simple orchestration layer
4. Handles Deprecated Methods: Clear deprecation messages for old methods

Facade Structure

class EnhancedStrategyService:
    def __init__(self, db_service: Optional[Any] = None):
        self.core_service = CoreStrategyService(db_service)
        # ... configuration settings
    
    async def create_enhanced_strategy(self, strategy_data: Dict[str, Any], db: Session) -> Dict[str, Any]:
        """Create a new enhanced content strategy - delegates to core service."""
        return await self.core_service.create_enhanced_strategy(strategy_data, db)
    
    # ... all other methods delegate to core_service
