How this case is verified
The case is the source's setup (or, where it has none, another source algorithm reversed). Setup: L' U' L2 F L' U F U2 Rw U2 Rw U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw' U2 Rw' x' U2 Rw' F2 L' U L U2. Every algorithm above was run by our logic engine from that state and reaches "oll-solved", keeping first-layers.
