How this case is verified
The case is the source's setup (or, where it has none, another source algorithm reversed). Setup: (-3,-4) / (0,-3) / (1,1) / (-3,0) / (-1,0) / (3,3) / (1,0) / (-2,-2) / (2,0) / (2,2) / (-1,0) / (-3,-3) /. Every algorithm above was run by our logic engine from that state and reaches "solved-up-to-layers".
