A stone-bearing automaton fired Blind through a warp mouth and one
wall, and the table saw nothing but the attack modal — the sight trace
only knew plain and bent-corner lines, so a legal shot read as a cheat.
When the attacker displays VISIONSTONE and no plain line exists,
stackSightTrace now finds the single edge whose removal opens the line
(warp legs included), draws the ray through it, and the keymap pulses
the dissolved wall so the answer to "how can he even see me?" is on
the board. Verified against the live LZ5R blind moment: warp mouths
at (0,2)W and (4,7)E, pierced wall V:3,8.
