The Shape Builder only used the filled areas of the selected paths, so a stroke-only line or open path across a shape did nothing. Like the reference app's Shape Builder, open paths now act as cutting edges: - pathops::shape_builder: with an open path in the selection, the regions are the Live Paint planar map's faces (every path an edge), so a line across a shape splits it and lines can enclose a region of their own; it also returns each open path cut where other paths meet it. Closed shapes alone, more than SHAPE_BUILDER_MAX_SEGMENTS segments, or a map that can't be built fall back to the filled-area arrangement. - Filled open paths count as closed (an invisible closing edge) where that encloses an area; unfilled open paths and straight lines stay edges. - shapeBuilder.merge: merging or deleting regions on both sides of a line piece removes that piece (the line is split, its other pieces kept); an area only lines enclose takes the current fill and the front-most object's look. Alt (erase) within `tolerance` of a line piece deletes it. Returns `lines` (pieces deleted). - shapeBuilder.regions also lists the line pieces. - The tool shares BuilderMap/Touched with the command, highlights the line piece under the pointer while Alt is held and passes its tolerance.
