Left West Wall

v1 Claude approved

Create the left side SIP wall, 122mm length x 756mm width x 1856mm height. The top surface must be cut at a 5.7 degree pitch to match the roof. The vertical edges and bottom edge foam core must be recessed by 45mm deep x 100mm wide to form a corner_spline and rebate_spline connection.
