Worked on stabilizing the test suite for the facebookresearch/param repository by addressing a persistent unit test failure. Focused on Python development and debugging, the approach involved identifying and correcting an incorrect import path for the comms_utils module, which had caused a ModuleNotFoundError and disrupted continuous integration reliability. By updating the test imports to reflect the new module structure, the fix restored consistent test execution across environments and reduced CI-related noise. This targeted change improved the feedback loop for contributors and minimized onboarding friction, demonstrating careful attention to risk management and codebase stability through precise unit testing and Python troubleshooting.
