# Directory Cleanup Summary

## Overview

The top-level directory has been cleaned and organized according to standard project structure conventions.

## Files Moved

### Test Files → `tests/`

1. **test_variable_tracking.py**
   - Comprehensive test for variable access tracking
   - Now in: `tests/test_variable_tracking.py`

2. **test_curses_basic.bas**
   - Basic test program for curses backend
   - Now in: `tests/test_curses_basic.bas`

### Documentation → `docs/`

1. **QUICK_REFERENCE.md**
   - Quick reference guide for MBASIC
   - Now in: `docs/QUICK_REFERENCE.md`

### Development Documentation → `docs/dev/`

1. **VARIABLE_TRACKING_CHANGES.md**
   - Documentation of variable tracking API changes
   - Now in: `docs/dev/VARIABLE_TRACKING_CHANGES.md`

## Files Remaining in Root (Correct)

### Essential Python Files
- **mbasic** - Main entry point (must be in root)
- **setup.py** - Package installation script (must be in root)

### Essential Documentation
- **README.md** - Project overview (must be in root)
- **INSTALL.md** - Installation instructions (must be in root)
- **requirements.txt** - Python dependencies (must be in root)

## Final Directory Structure

├── setup.py                     ✅ Package setup

```

## Benefits

1. **Cleaner Root Directory**
   - Only essential files in root
   - Easier to navigate
   - Professional appearance

2. **Better Organization**
   - Tests in `tests/`
   - Docs in `docs/`
   - Dev docs in `docs/dev/`
   - Source in `src/`

3. **Standard Conventions**
   - Follows Python project conventions
   - Matches expectations for contributors
   - Easier for tools to find files

4. **Improved Maintainability**
   - Clear separation of concerns
   - Easy to find related files
   - Reduced clutter

## Verification

All files successfully moved:
```bash
# Root directory now contains only:
$ ls *.py *.md *.txt
INSTALL.md
README.md
mbasic
requirements.txt
setup.py

# Tests moved to tests/:
$ ls tests/test_variable* tests/test_curses*
tests/test_curses_basic.bas
tests/test_variable_tracking.py

# Documentation organized:
$ ls docs/*.md docs/dev/*REMOVAL* docs/dev/*TRACKING*
docs/QUICK_REFERENCE.md
docs/dev/NPYSCREEN_REMOVAL.md
docs/dev/VARIABLE_TRACKING.md
docs/dev/VARIABLE_TRACKING_CHANGES.md
```

## No Breaking Changes

All file moves preserve functionality:
- ✅ Tests still work (relative paths maintained)
- ✅ Documentation still accessible
- ✅ mbasic still runs from root
- ✅ Import paths unchanged (source in `src/`)

## Cleanup Complete

The directory structure is now clean, organized, and follows best practices for Python projects.
