+## Native Editor Follow-up
+
+A native-editor replay on 2026-07-13 loaded the collider diagnostics scene, exercised Draw Brush
+Preview/cancel, and grouped two hierarchy actors through undo/redo. The replay exposed two issues
+that source-only checks did not make visible: command execution left a collapsed palette title bar,
+and the viewport icon child briefly inherited from a group actor without Bevy visibility hierarchy
+components. Both paths now have focused regression assertions; a rebuilt replay dismissed the
+palette completely and emitted no hierarchy warning.
+
 No screenshot is required for this ticket: the accepted surface is lifecycle, rollback, cleanup, and
 history behavior exercised through headless production entry points. Live command/status checks add
 confidence but are not substituted for semantic assertions. Packaged-runtime testing remains
