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