Electron rewrites ~/.config/Claude for as long as the app runs, so removing the package and deleting the directory while it is open leaves the app running and the directory back within the same second, holding fresh Preferences and crash-reporter state. Driven end to end on an edge worker: remove via the menu with the app open left 11 processes and a recreated ~/.config/Claude; with the app quit first the directory stayed gone. The test stubs pkill so the suite cannot take a developer's own Claude with it, and asserts the remover reached for it.
