Hold the puzzle as drawn, with the solved layer (a centre and its corners) where it is; the algorithms include the rotations from there. The other corners' colours give the shape (peanut, pi, ...); the centres give the permutation within it.

How this case is verified

The case is the source's setup (or, where it has none, another source algorithm reversed). Setup: B' r R' B x R r' R r'. Every algorithm above was run by our logic engine from that state and reaches "solved".
