How this case is verified

The source's case image defines this case; its setup is reconstructed and checked against that independent pattern. Setup: Ro U B' U' R' U B U' Ro' BL' L' BL L R' L' BL' L BL R'. Every algorithm above was run by our logic engine from that state and reaches "solved-up-to-r".
