MCP demo v3 (enclosure_ui_mcp.py --story v3, default): one standoff placed from the parameters (width/2 - inset, depth/2 - inset) and patterned 2 x 2 in the Rectangular Pattern dialog with spacings width - 2*inset and depth - 2*inset, then width 80 -> 100 and wall 2 -> 3 typed into the Parameters dialog; record_v2.sh is now record_ui.sh STORY. A pattern's Direction can be a straight model edge (an edge along an origin axis points the axis's way), scenario pattern_direction_edge. Dialog rows publish their widgets as dialog:<label> handles (combo items dialog:<label>:<item>, OK), the Parameters dialog its expressions (param:<name>), title and close button
