Timeline editing: double-click or Edit Feature reopens the feature's dialog filled in (model rolled back to it, references highlighted) and rebuilds it in place; history marker drag; drag to reorder with dependency checks; context menu (edit, edit profile sketch, rename, suppress, roll marker here, find in browser, delete with dependents); hover links timeline and geometry; fillet edges and hole positions re-resolve after upstream edits (warnings when moved)
