| Patch type | Example fix | |------------|--------------| | Parity bug | OLL parity fix for 4x4x4 and 6x6x6 when reduction fails. | | Performance | Replace recursion with iteration in center solving. | | Memory | Use array('H') instead of Python lists for move tables. | | Visualization | Fix print_cube() for N>5 (alignment issues). | | Scramble generator | Patch random move sequence to avoid inverse cancellations. | | Algorithm correctness | Correct commutator for last two centers on odd N. | | Metric | Original (unpatched) | Patched version

Step 1: Cube Representation

We'll use a flat list for performance, avoiding nested lists.
