CHANGELOG
Only document user-facing changes (features, bug fixes, removed support).
Test tooling changes (e.g. Pipfile, Pipfile.lock) are not user-facing → no entry needed.
Wording for Python version support: declare compatibility with \python3.X``
Pull requests
Rebase on master before opening a PR.
One commit per PR; amend rather than adding new commits.
Force-push with --force-with-lease on feature branches.
Never force-push to master.
Always open a pull request — never push directly to master.
CI failures
Fix CI failures automatically, iterating until all checks are green — no need to ask first.
Pipfile / dependency management
Generate Pipfile.lock on the lowest supported Python version.
When a package is a conditional transitive dependency (e.g. dill, typing_extensions)
whose pip markers depend on the lock-generation Python version, add it explicitly as a
direct dependency in Pipfile (without a version marker) so it installs on all supported
Python versions.
When constrained packages (e.g. setuptools, urllib3) need to override transitive
resolution, put them in [packages], not [dev-packages].
