Start by clarifying the desired rollback behavior for the VSCode and IntelliJ integrations, including which versions should be selectable and how “Last LTS” is determined. Identify the version-selection entry points and document the acceptance criteria; the work is done when users can choose a specified or LTS version and the resulting integrations operate without the reported errors.
