3x3 — Roux

Left/right blocks (intuitive), then CMLL, then LSE: orient the edges, place UL and UR, solve the M slice.

The CMLL cases are from your notes. The LSE steps (4a, 4b, 4c and DFDB) are not from your notes: the structure follows the community descriptions linked at the bottom, and every algorithm and table was found or checked with the cube simulator. Your own recorded LSE card is kept at the end, with a question about it.
