Summary

Preserve the complete supported Python range on pull requests while moving compatibility ownership out of GitHub Actions.

  • no Python-version matrix or CI-side subprocess/session-name orchestration
  • noxfile.py owns supported versions and uv-backed isolated environments
  • dev/test_all.sh is a tiny tagged-Nox wrapper and make test-all is the local entrypoint
  • CI invokes the same wrapper through uv
  • package build and wheel installation/parser verification run once on the primary environment, avoiding concurrent dist/ writes
  • path gating and superseded-run cancellation remain; when the workflow is triggered, the test job runs for draft and ready-for-review PRs alike

Future supported-version changes are localized to Nox configuration.

Review Change Stack

Walkthrough

The PR adds Nox-based testing for Python 3.10–3.13. It adds a strict wrapper script and a make test-all target that run the CI-tagged sessions with pinned Nox tooling.

Changes

Cross-Python testing

Layer / File(s) Summary
Nox CI test session
noxfile.py
Nox configures uv-backed environments for Python 3.10–3.13. The CI-tagged session performs a frozen dependency sync with all extras and runs dev/test_python.sh.
Test-all command entry point
Makefile, dev/test_all.sh
The test-all target installs pinned nox[uv] tooling and invokes the strict wrapper. The wrapper resolves the repository root, runs nox --tags ci, and forwards arguments.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b3b1e

The CI changes can run every compatibility session with the project’s default Python instead of the selected supported version, leaving version-specific regressions undetected. Merge should wait until the wrapper uses the interpreter selected by each session.

Poem

A rabbit hops through versions bright,
From three-ten onward, tests take flight.
Nox prepares each tidy den,
The Makefile calls them all again.
“Green runs!” I thump with cheer.

Use the selected Nox interpreter for the test command.

When .venv exists, dev/test_python.sh ignores UV_PROJECT_ENVIRONMENT and runs ${MODULE_DIR}/.venv/bin/python. The Python-version Nox sessions can therefore run tests with the project interpreter instead of their configured session interpreters. Make the wrapper prefer UV_PROJECT_ENVIRONMENT, or invoke python -m pytest directly from the Nox session.
