# Code Cleanup Summary

## What Was Done

### ✅ Files Moved to `archived_scripts/`

7 unused/utility scripts have been organized into a separate folder:

1. **`api.py`** - FastAPI alternative implementation (not used by streamlit_app.py)
2. **`audit_collection_names.py`** - SQLite debugging/auditing script
3. **`cleanup_chroma.py`** - ChromaDB cleanup utility
4. **`create_architecture_diagram.py`** - Standalone diagram generation
5. **`create_ppt_presentation.py`** - Standalone PowerPoint generation
6. **`create_trace_flow_diagrams.py`** - Standalone flow diagram generation
7. **`example.py`** - Example usage script (non-production)

### ✅ Code Review Report Created

A comprehensive `CODE_REVIEW_REPORT.md` has been generated with:
- **Architecture Assessment**: Well-designed modular system ✅
- **Code Quality Analysis**: Good with minor improvement areas
- **Recommendations**:
  - Priority 1: Add structured logging, improve error handling
  - Priority 2: Add input validation, performance monitoring
  - Priority 3: Add constants file, unit tests

### 📊 Project Structure After Cleanup

```
Main Production Code (9 core files):
- streamlit_app.py, run.py, config.py
- vector_store.py, llm_client.py, embedding_models.py
- chunking_strategies.py, dataset_loader.py
- trace_evaluator.py, evaluation_pipeline.py, advanced_rag_evaluator.py

Recovery/Utility Scripts (6 files):
- rebuild_chroma_index.py, rebuild_sqlite_direct.py
- recover_chroma_advanced.py, recover_collections.py
- rename_collections.py, reset_sqlite_index.py

Test Scripts (2 files):
- test_llm_audit_trail.py, test_rmse_aggregation.py

Archived/Non-Production (7 files in archived_scripts/):
- Example, API, utilities, documentation generators
```

## Key Findings

### ✅ Strengths
- **Factory Pattern**: Excellent implementation in EmbeddingFactory, ChunkingFactory
- **Rate Limiting**: Intelligent rate limiter for Groq API
- **Modular Design**: Clear separation of concerns
- **Configuration**: Type-safe settings with Pydantic

### ⚠️ Areas for Improvement
- Add structured logging instead of print() statements
- Replace broad `except:` with specific exceptions
- Add comprehensive type hints to all functions
- Create constants/configuration for magic numbers
- Add input validation to public methods

## Files Not Moved (Why)

**Recovery Scripts** remain in main directory because they are:
- Critical for database maintenance (rebuild_*.py, recover_*.py)
- Required troubleshooting tools
- Part of system reliability

**Test Scripts** remain in main directory because they are:
- Used for validation and quality assurance
- Important for development workflow
- Not "unused" - they serve testing purposes

## Next Actions

1. Review `CODE_REVIEW_REPORT.md` for detailed recommendations
2. Consider implementing Priority 1 improvements (logging, error handling)
3. Periodically review archived_scripts/ folder
4. Archive can be deleted if files are never referenced again
