Cleanup removed only the three directories, so a run that stopped between creating the symbolic link and removing it left the link behind and every later run failed at its creation with EEXIST. Cleanup now also removes the plain file and the link, and the link name and plain file name moved to namespace scope. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
