CLS
Cross Color Facing Front
Groups follow where the corner's cross colour faces (up, front or right), or the corner trapped in its slot; within a group, the top corners' colours.

How this case is verified
The case is the source's setup (or, where it has none, another source algorithm reversed). Setup: R' U R' U R' U R U2' R U' R2' U2' R'. Every algorithm above was run by our logic engine from that state and reaches "f2l-oll".
