A share child was drawn in the measuring room and again in its slot, and one record holding two questions made every local change under it defer to the span. Where a rule or a hint gives the length along the span, the first ask answers nothing the rule does not, so the child is asked once, in its slot; the widgets that always report the whole of their box now say so. A hint with a fraction resolves against the frame and pins it. The dump rig prints every cold layout so a change to it shows in a diff.
