If the current sudoku still requires copying so much identical/similar code between external libraries and internal libraries, why not simply put all related content into the transport/sudoku directory?

The current dependency on the official sudoku repository is confusing, relying on a special tag version outside the main branch, while there's a lot of duplicate code on both sides.

In simple terms, the special tag differs from the main branch only in terms of go mod. It can also be considered akin to the difference between the dev branch and the stable branch—one is version 1.20 and the other is 1.24. This setup is meant to meet the requirements of mihomo. Additionally, I need to think about how to split and merge the packages for the complete porting work, so please merge this pull request first

Indeed, we will merge that PR.

However, I feel that continuing like this will make subsequent maintenance increasingly difficult, and we need to resolve these issues as soon as possible.

i will, thx a lot
