Twinkle Rathod focused on environment hygiene and configuration cleanup for the Prof-Drake-UMD/INST767-Sp25 repository, targeting JupyterLab workspace management. She implemented the removal of obsolete workspace configurations by deleting the .jupyter/desktop-workspaces directory, resetting the environment to a clean default state. This approach addressed configuration drift and reduced user confusion by ensuring that stale settings no longer impacted onboarding or daily use. Her work involved Git-based repository hygiene, Unix command-line operations, and JupyterLab workspace handling. The changes improved reproducibility and lowered support overhead, demonstrating a methodical approach to environment management, though the scope was limited to a single feature update.
