3x3 CMLL T Bottom Row algorithm

Solve the four upper corners in Roux after building both side blocks; the remaining edges are solved later.

T Bottom Row belongs to the T group in CMLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Upper edges with that color facing up: UF, UB, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: B B; R: L U; B: F F; L: U R. The letters identify colors by their reference faces.

The opening is Rw' U Rw; the final segment is R F' R. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
