🏗️ Priority 2A: Architecture Consolidation & Optimization Complete

✅ **PHASE 1: App Consolidation**
- Consolidated 8 app variants into single robust app.py with intelligent mode selection
- Created archive/app_variants/ to preserve all previous versions
- Enhanced ConsolidatedGAIAInterface with advanced capability detection
- Added graceful degradation for missing dependencies
- Unified interface supporting demo, individual, and comprehensive testing modes

✅ **PHASE 2: Architecture Decision - Hybrid Approach**
- Created main_hybrid.py combining best of legacy and refactored architectures
- Intelligent architecture selection: refactored → legacy fallback
- Unified interface regardless of underlying architecture
- Environment variable control (GAIA_ARCHITECTURE=auto/legacy/refactored)
- Production-proven legacy with modern modular benefits

✅ **PHASE 3: Production Optimization**
- Optimized requirements.txt with core vs optional dependencies
- Added comprehensive health_check.py for system monitoring
- Integrated health check into web interface with detailed reports
- Added dependency fallback strategies throughout codebase
- Enhanced error handling and graceful degradation

**🎯 CONSOLIDATION ACHIEVEMENTS:**
- ✅ **Single App Interface**: 1 robust app vs 8 variants (87.5% reduction)
- ✅ **Architecture Flexibility**: Hybrid system with intelligent selection
- ✅ **Optimized Dependencies**: Faster HF Space startup with optional deps
- ✅ **Production Monitoring**: Built-in health checks and system status
- ✅ **Maintainability**: Clean codebase with archived backups

**🔧 TECHNICAL IMPROVEMENTS:**
- Capability detection system for graceful feature availability
- Hybrid solver with unified interface for both architectures
- Health monitoring with dependency, API key, and component checks
- Optimized requirements with clear core vs optional separation
- Enhanced error handling throughout the application stack

**📊 EXPECTED BENEFITS:**
- **Faster Deployment**: Optimized dependencies for quicker HF Space builds
- **Better Stability**: Graceful handling of missing components
- **Easier Maintenance**: Single consolidated interface vs multiple variants
- **Enhanced Monitoring**: Real-time system health and capability tracking
- **Future-Ready**: Clean foundation for additional feature development

This establishes a production-optimized, maintainable foundation while preserving
all existing functionality and the 85% accuracy performance.

+            
+            **Research Questions:**
+            - "Who nominated the only Featured Article about a dinosaur promoted in November 2016?"
+            - "What are the ingredients in the audio file?"
+

+            - "What is the best move for Black in this chess position?" (with chess image)
+            
+            **Excel Processing:**
+            - "What is the total of all food sales excluding drinks?" (with Excel file)
+            
+            **Multimedia Analysis:**
+            - "How many different bird species can be seen simultaneously in this video?"
