Separate minimal test dependencies from development tools to allow supporting Python 3.9+ users while using modern dev tools that may drop support for older Python versions. - test: minimal deps for running tests (pytest, pandas, polars) - dev: linting, formatting, coverage tools (ruff, pyrefly, coverage)
Separate testing, linting, and coverage into independent jobs: - test: runs on Python 3.9-3.13 with minimal test dependencies - lint: runs on Python 3.13 only with dev tools - coverage: runs on Python 3.13 only with dev tools This allows dev tools to drop support for older Python versions without breaking library compatibility testing on those versions.
Add Python 3.14 to test matrix and package classifiers to ensure forward compatibility with the upcoming Python release.
Demonstrates that the new dependency split works correctly: - coverage 7.11.0+ requires Python 3.10+ - Environment marker ensures it only installs on Python 3.10+ - Python 3.9 test jobs will skip coverage (they only use test group) - Python 3.13 coverage job will use latest coverage This validates that dev tools can freely upgrade without breaking Python 3.9 library support.
Rename workflow to 'CI' and add descriptive job names: - 'CI / Python 3.9' instead of 'test / test (3.9)' - 'CI / Lint & Type Check' instead of 'test / lint' - 'CI / Code Coverage' instead of 'test / coverage' - 'CI / Optional Dependencies (Python 3.9)' etc. - 'CI / Isolation both (Python 3.9)' etc. Makes GitHub PR checks much more readable for reviewers.

Summary
Separate minimal test dependencies from development tools to enable supporting Python 3.9+ users while using modern dev tools that may drop support for older Python versions.
Changes
Dependency Groups
CI Workflow
Split monolithic build job into focused jobs:
--group testonly--group test --group dev--group test --group devPython 3.14 Support
Added Python 3.14 to test matrix and package classifiers.
Validation
Upgraded coverage from 7.10.6 to 7.11.0+ (requires Python 3.10+) with environment marker. This demonstrates that:
