Corners of the last layer, M-slice free (CMLL)
Solve the four top corners after both Roux blocks: 42 cases.
What it is
CMLL is Roux's third step: with both 1x2x3 blocks built, one algorithm orients and permutes the four top-layer corners. The M slice and the top edges may be disturbed freely, since LSE solves them next, which is why CMLL algorithms can be shorter than COLL.
The cases are the eight corner-orientation shapes (O for all oriented, plus H, Pi, U, T, Sune, Antisune, L), each split by permutation.
Recognition
Find the orientation shape from the top-colour stickers, then read the side stickers of the corners for headlights and opposite colours, as in COLL.
