Developed a data preservation safeguard for the tw93/Mole repository, focusing on safer uninstallation workflows for shared-name CLI tools. The solution introduced a deny-list and refined deletion logic in Shell, ensuring that uninstall processes do not remove state directories belonging to other independently shipped tools. This approach addressed edge cases involving case-insensitive naming collisions and respected XDG directory conventions across multiple user paths. Comprehensive regression tests were added using bats to validate preservation scenarios, with all tests passing. The work emphasized robust shell scripting, thorough testing, and careful version control practices, resulting in improved reliability for users managing multiple CLI and GUI tools.
