Normaly sudoku rules apply.
Ten Lines: Digits along gray lines must be broken into one or more contiguous groups of cells that add to ten. Such groups cannot overlap. Digits may repeat within such sums if allowed by other rules. For example, 513173 is a valid fill for a length 6 line, because it can be broken into 5131 and 73, each of which sum to 10.
Parity Lines: Digits along red lines must strictly alternate between even and odd.

Very elegant construction as per usual, thanks. And is this one CTC missed? I don't recall doing it before.

I love how going into this I expected the arrangement of each clue to be exceptionally placed and I was not disappointed. Fantastic!

The opening was really a wild ride for me but the later half still remained the entertaining value there, lots of cool interactions in here! :)

Very nice use of the parity characteristics of ten lines! They combine so well with the parity lines. Thanks for this lovely puzzle!

Very challenging opening followed by easier, but still non-trivial, mid solve and conclusion. This definitely kept me on my toes!
