Worked on the UKGovernmentBEIS/inspect_evals repository to address a deployment issue related to tar extraction in the Core-Bench setup. Focused on stabilizing the extraction process by introducing the --no-same-owner flag to tar commands, which resolved ownership-related permission errors during deployment. Updated the associated tests to align with the new setup flow, ensuring that future regressions would be caught early. The solution was implemented using Python and shell scripting, with an emphasis on targeted bug fixing and robust testing practices. The work resulted in improved reliability for deployment pipelines without introducing risk to other parts of the system.
