First steps

  1. Read the whole issue, then the project's contributing guide.

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Reproduce the report with the listed git clone, pip install ., and pytest commands. Start with tests/conftest.py and the failing tests in tests/test_advanced.py, tests/test_basics.py, and tests/test_shutdown.py, then inspect the pluginbase.py paths shown in the traceback; done means the test suite completes without these setup errors and failures.
