Structured configuration management

Configuration files should follow official standards, have up-to-date tool settings, and appropriate dependency constraints. This ensures consistent behavior across environments and compatibility with the project’s requirements.

For pyproject.toml:

1. Organize sections according to packaging specifications (e.g., place dependency-groups under the project section)
2. Keep tool configuration versions aligned with project requirements:

   [tool.ruff]
   target-version = 'py39'  # Should match minimum supported Python version
   

3. Manage dependency constraints carefully, considering Python version compatibility:

   # Option 1: Version constraints with conditions
   "sqlalchemy>=2.0,<3.0; python_version < '3.13'"
      
   # Option 2: Simpler constraints when appropriate
   "sqlalchemy>=2.0,<3.0"
   

Regular audits of configuration files should be performed when upgrading dependencies or changing supported Python versions to ensure configurations remain correct and optimal.
