## Workarounds

1. **** (98% success)
   ```
   python -m pip install pytest-benchmark
python -m pytest --benchmark-only -q
   ```
2. **** (90% success)
   ```
   which pytest
pytest --version
python -m pytest --version
python -m pip install pytest-benchmark
   ```

## Dead Ends

- **** — The plugin registers the fixture via entry points; a plain import does not register it if the package is missing. (80% fail)
- **** — Shadows the real plugin and provides no timing functionality; tests pass but measure nothing. (70% fail)
