From memo: the pair's letters are the case. The diagram shows the buffer and both targets lettered, the rest greyed.

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