I saw that you copied the updated rules descriptions from the CVP Jocly presets, which is good. I made some fixes to these to improve clarity and remove a few typos I found. I will admit in advance that I am kind of a stickler for consistency, but if you can make those changes that would be great.
For Hectochess and Seireigi you can simply copy the code from the CVP rules files. The only thing you might have to fix is the Lance graph path in the Seireigi file.
For Chu Seireigi the rules description on the biscandine site is much better, but there are still a few discrepancies, and a few pieces are listed twice for some reason. I'd recommend simply copying the source code from the CVP Rules description to fix the text, and copying over the pictures whose links I have attached below.
