clnrm run tests/

# Validate configuration
clnrm validate tests/

# Show available plugins
clnrm plugins

## Project Structure

- `scenarios/` - Test scenario definitions
- `README.md` - This file

## Framework Self-Testing

This project demonstrates the cleanroom framework testing itself through the "eat your own dog food" principle.
