- Add broken preferences detection using plutil -lint validation - Add broken login items cleanup (LaunchAgents pointing to missing files) - Add universal binary slimming (opt-in via MOLE_SLIM_BINARIES=true) - Protect Spotify cache if >500MB (likely contains offline music) - Warn when browsers are running before cache cleanup - All cleanup stats properly counted in final summary
