Create Wall refused the board-edge openings: no far cell, so "walls must be created between two spaces". But bricking over a lettered opening is a classic play, and the far space is the tunnel itself. A warp mouth now counts as wallable — with the wall raised at BOTH mouths, since a tunnel has one passage: no walking in from the far board, no warp sight through a sealed pair, and tearing down either end reopens both. The client grows edge hitboxes at the perimeter mouths so the line is clickable at all. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
