# Security

Decorators in `modules/webutils.py` enforce access control.

- **`@login_required`**: Restricts routes to authenticated users by checking `user_id` in the session.
- **`@project_access_required`**: Restricts project data to its owner. Resolves `project_name` from route params, query args, or JSON payloads.
