Hovering a wall-junction link-toggle icon today only swaps the icon shape — the user doesn't see which wall the click will disconnect from until after they click. ATPATH (T-junction) configurations especially make the partner ambiguous when multiple connections sit close together. On hover, paint a wireframe bbox around the partner wall using the same shader, constants and color the array module already established for its layer-children highlight (POLYLINE_UNIFORM_COLOR, decorator_color_special, line width 1.8, alpha 0.8). The line-width / alpha constants in decorator.py are renamed from _ARRAY_LAYER_BBOX_LINE_* to _BBOX_HIGHLIGHT_LINE_* and shared between draw_array_layer_children_bbox and the new draw_wall_partner_bbox so the two highlights stay in lockstep. The trigger lives in a new GizmoWallLinkToggle subclass in wall.py which keeps the base gizmos.GizmoLinkToggle generic (per the generic-naming convention for shared widgets). The subclass's draw() calls super().draw(context) then on self.is_highlight outlines its partner_obj via the shared decorator helper. Same trigger pattern as GizmoArrayLayerIndicator. Blender's Gizmo API exposes target_set_operator but no symmetric getter, so the partner reference can't be read back from the bound operator handle. Instead GizmoWallUnjoinSingle.position_gizmos mirrors the resolved partner_obj onto each visible icon every frame next to the existing other_wall_guid write — the icon's draw() reads from its own __slots__-declared attribute. A forward-compat AST test pins the contract: GizmoWallLinkToggle.draw must reference is_highlight and call draw_wall_partner_bbox. Catches the regression where someone tidies the draw() override into super() or replaces the shared helper with an ad-hoc draw call. Generated with the assistance of an AI coding tool.
