## 🎯 Quick Reference by Task

### Running the Application
```bash
python run.py              # Quick start launcher
streamlit run streamlit_app.py  # Direct web interface
```

### Core System Modules
- **Data Pipeline**: `dataset_loader.py` → `vector_store.py` → `embedding_models.py`
- **Query Pipeline**: `llm_client.py` → `trace_evaluator.py`
- **Orchestration**: `evaluation_pipeline.py` (coordinates everything)

### Database Maintenance
- **Corruption detected?** Run recovery scripts:
  - `recover_chroma_advanced.py` (recommended first)
  - `rebuild_chroma_index.py` (full rebuild)
  - `recover_collections.py` (collection-specific)

### Development & Testing
- **Test evaluation**: `test_llm_audit_trail.py`
- **Test metrics**: `test_rmse_aggregation.py`
- **Example usage**: See `archived_scripts/example.py`

## 📊 File Statistics

| Category | Count | Status |
|----------|-------|--------|
| Core Production | 11 | ✅ Active |
| Recovery/Utilities | 6 | ✅ In Use |
| Test Scripts | 2 | ✅ In Use |
| Archived | 7 | 📦 Not Used |
| Configuration | 5 | ✅ In Use |
| **Total** | **31** | **Clean** |

## 🔄 Why Files Were Moved

### Archived Files (7 total)
These files do NOT have any imports in the active codebase:
- **api.py** - Alternative FastAPI backend (not used; main app is Streamlit)
- **example.py** - Demo script; not part of production pipeline
- **Diagram/PPT generators** - Documentation tools; run standalone only
- **Audit script** - Development debugging tool; not in main flow
- **Cleanup script** - Maintenance utility; not in main flow

### Preserved Files (20 total)
These files ARE actively imported:
- **Core modules** - Required by streamlit_app.py and run.py
- **Recovery tools** - Critical for database maintenance
- **Test scripts** - Part of quality assurance process

## ✅ Code Review Highlights

### Strengths Found
✅ Well-structured modular architecture  
✅ Excellent factory pattern implementation  
✅ Intelligent rate limiting for API  
✅ Type-safe configuration with Pydantic  
✅ Clear separation of concerns  

### Improvement Recommendations
⚠️ Add structured logging (replace print statements)  
⚠️ Improve error handling (too many broad exceptions)  
⚠️ Add comprehensive type hints  
⚠️ Add input validation  
⚠️ Add performance monitoring  

**See CODE_REVIEW_REPORT.md for detailed analysis and recommendations**

## 📝 Notes

- **Recovery Scripts**: These are NOT "unused" - they're critical maintenance tools kept in main directory
- **Test Scripts**: These are NOT "unused" - they're part of development workflow
- **Archive**: Safe to delete archived_scripts/ if files are never needed again
- **Git**: All files remain in git history; no data is lost
