How this case is verified
The source's case image defines this case; its setup is reconstructed and checked against that independent pattern. Setup: Dv2' R' U2' R' F R F' R U' R' U2' R Uv2' U2. Every algorithm above was run by our logic engine from that state and reaches "f2l-oll", keeping first-layers.
