Beautiful and tough. I tried a few interpretations of the border clues before I found one that worked. Happy hunting. Happy New Year. Looking forward to a sequel.

Second rule doesn't make sense.
Values are digits in this puzzle, and a digit on the line is obviously on the line.
Edited Answer: I get the confusion 'the sum of two digits separated by the line' part only apply to the line parts in box 2 that goes between cells.
Edit: The rule says "the values ALONG THE LINE are either A or B", but they are always A because they are always equal to themselves.
