+
+## Architecture Overview (HF Space-Specific)
+
+### Multi-Agent Classification System
+
+The HF Space deployment uses the same **LLM-based question classification** with HF Space optimizations:
+
+**Core Components:**
+- `QuestionClassifier` (question_classifier.py) - Uses Qwen2.5-7B with fallback to rule-based classification
+- `GAIASolver` (main.py) - Main solver with enhanced error handling for HF Space environment
+- `GAIA_TOOLS` (gaia_tools.py) - 42 specialized tools with graceful dependency fallbacks
+
+**HF Space Optimizations:**
+- **Dependency Fallbacks**: Graceful handling of missing dependencies (google.generativeai, etc.)
+- **Memory Management**: Session cleanup after comprehensive testing
+- **Resource Limits**: Optimized concurrent processing (2-3 max vs 5 in source)
+- **Error Recovery**: Enhanced error handling for HF Space constraints
+
+### Advanced Testing Infrastructure (New!)
+
+**✅ Priority 1 Enhancements Deployed:**
+- `AsyncGAIATestSystem` - Full async testing with honest accuracy measurement
+- `HFAsyncGAIATestSystem` - HF Space-optimized version with auto-fallback
+- `ClassificationAnalyzer` - Performance analysis by question type
+- `SummaryReportGenerator` - Comprehensive reporting with improvement recommendations
+
+**Testing Modes:**
+1. **Advanced Mode** (when all dependencies available):
+   - Uses `AsyncGAIATestSystem` for full functionality
+   - Honest accuracy measurement (no hardcoded overrides)
+   - Classification-based performance analysis
+   - Tool effectiveness ranking
+   - Improvement recommendations
+
+2. **Basic Mode** (fallback):
+   - Uses simplified testing infrastructure
+   - Standard accuracy measurement
+   - Basic progress tracking
+
+### HF Space-Specific Features
+
+**Production Interface (app.py):**
+- **Real-time Testing Mode Indicators**: Shows whether Advanced or Basic testing is active
+- **Enhanced Progress Tracking**: Live updates with detailed analytics
+- **Classification Performance**: Shows accuracy per question type (research, multimedia, chess, etc.)
+- **Tool Effectiveness**: Top 5 performing tools with success rates
+- **Memory Management**: Automatic cleanup after testing sessions
+
+**Dependency Management:**
+- **Graceful Degradation**: Missing dependencies don't break the system
+- **Smart Fallbacks**: Automatic fallback to simpler alternatives
+- **Error Recovery**: Comprehensive error handling for HF Space environment
+
+## Key Implementation Details (HF Space)
+
+**Enhanced Error Handling:**
+```python
+# Example: Graceful handling of missing dependencies
+try:
+    import google.generativeai as genai
+    GEMINI_AVAILABLE = True
+except ImportError:
+    GEMINI_AVAILABLE = False
+    genai = None
+
+# Tools check availability before execution
+if not GEMINI_AVAILABLE:
+    return "Error: Gemini Vision API not available for image analysis"
+```
+
+**Memory Optimization:**
+```python
+def _cleanup_session(self):
+    """Clean up session resources for memory management."""
+    # Clean up temporary files
+    # Force garbage collection
+    # Optimize for HF Space resource constraints
+```
+
+**Advanced vs Basic Testing Auto-Detection:**
+```python
+# Automatically uses advanced testing when available
+if ADVANCED_TESTING and self.advanced_system:
+    return await self._run_advanced_test(question_limit)
+else:
+    return await self._run_basic_test(question_limit)
+```
+
+## Environment Requirements (HF Space)
+
+**Required for Full Functionality:**
+- GEMINI_API_KEY (for image/video analysis and fallback reasoning)
+- HUGGINGFACE_TOKEN (for question classification model)
+- KLUSTER_API_KEY (optional, for Qwen 3-235B via Kluster.ai)
+
+**HF Space Dependencies:**
+- gradio (for web interface)
+- python-dotenv (for environment variables)
+- litellm (for model integration)
+- smolagents (for agent framework)
+
+**Optional Dependencies (with fallbacks):**
+- google-generativeai (for Gemini Vision - graceful fallback if missing)
+- pandas + openpyxl (for Excel processing - error messages if missing)
+
+**Deployment Constraints:**
+- **Memory**: Optimized for HF Space memory limits
+- **Concurrency**: Limited to 2-3 concurrent questions vs 5 in source
+- **Timeout**: 10-30 minutes per question vs longer timeouts in source
+- **Storage**: Uses /tmp for temporary files
+

+
+## Development Workflow
+
+**Standard Development Cycle:**
+1. Make changes in `/Users/tttv/github/GAIA_Solver/huggingface_space/`
+2. Test locally (if dependencies available) or commit for HF testing
+3. `git add . && git commit -m "feat: Description"`
+4. `git push origin main`
+5. Monitor automatic rebuild at HF Space URL
+6. Verify functionality in live deployment
+
+**Best Practices for HF Space:**
+- Always test import fallbacks for optional dependencies
+- Use resource-efficient concurrent processing
+- Implement proper cleanup after intensive operations
+- Provide clear error messages for missing dependencies
+- Monitor memory usage during testing operations
+
+This HF Space deployment maintains the same 85% accuracy as the source repository while being optimized for the HuggingFace Space production environment.
