Code Review Summary

Security Issues

.github/workflows/pytest.yml - Actions not pinned to specific SHA hashes:

• Line 24: actions/checkout@v4 - should be pinned like other workflows
• Line 28: actions/setup-python@v5 - should be pinned like other workflows
• Line 33: astral-sh/setup-uv@v5 - should be pinned like other workflows

Other workflows (build-docs.yaml, ci.yaml, lint.yaml) properly pin these actions to specific commit SHAs.

Test Coverage Issues

action_files/test_ray.py:6 - Outdated skip condition:

if sys.version_info >= (3, 12):
    pytest.skip("Ray requires Python<3.12", allow_module_level=True)

This skips Ray tests for Python >= 3.12, but according to the PR's changes, Ray is only unavailable for Python 3.14+. The condition should be sys.version_info >= (3, 14) to match other Ray-related skips in the codebase.

Code Quality Issues

tests/test_distributed_fugue.py:10-12 - Unused imports:

• DaskExecutionEngine from fugue_dask
• SparkSession from pyspark.sql

pyproject.toml - Dependency group version inconsistencies:

• Line 71: dask group uses fugue[dask]>=0.8.1
• Line 81: all group uses fugue[dask]>=0.9.4
• Line 76: spark group uses fugue[spark]>=0.8.1
• Line 82: all group uses fugue[spark]>=0.9.4

Consider aligning these version constraints.

Minor Consistency Notes

• File extension: pytest.yml uses .yml while all other workflows use .yaml
• Lint workflow uses actions/setup-python@42375524e23c412d93fb67b49958b491fce71c38 # 5.4.0 while other workflows use v5.6.0
