# Contributing

## Branching

- `main` is stable.
- `develop` is the integration branch.
- Feature branches use: `feature/<name>`.

## Safety Rules

Never commit personal music library files, Serato databases, or crates.

Never write repair code without dry-run mode, backup plan, and rollback log.

## Testing

Install development dependencies with `python3 -m pip install -e '.[dev]'`.

Run `pytest` before committing. Tests and fixtures must use synthetic library data.
