UI scenarios: the user's four open bugs as ignored targets (s31 sketch on a face projects its loops, s32 a cut in the active component leaves others alone, s33 Move opens at 0 and its X arrow moves along X, s34 moving a component carries its sketches); Fold, configurations, motion study and autosave/recovery enabled against the landed features (s22–s25); retests: fillets follow their edge after a sketch edit (s06 volume, s15 widens the sample plate), one canvas panel (s19); s30 patterns a hole as a feature (ignored: one hole results). Harness: manipulator handles published by name (scenario::publish_handle; ui.at {handle}; timeline items as timeline:<name>), restart after a crash or close, autosave into the scenario's folder, exact widget text before menu-label prefixes, checks for sketch curves, body volume and sketch points in the world
