Well, it's off topic, I see two BUG+1 moves in your "All possible steps". The "Bivalue Universal Grave + 1: => r3c1 <> 7" is wrong.

BTW, the full form of BUG is "Bivalue Universal Grave". Either it should be 7r3c1 or r3c1<>59.

When I optimize the code, a clerical error results in a text prompt error, and I mistakenly write an equal sign as an unequal sign.
Since the execution result is not affected, it is not found by the self check of the solver.
