Cantor´s Blue

Hey! Hope you had a wonderful Christmas and a better New Year. It´s been months without publishing so here we go again.
Normal sudoku rules apply: Place the digits 1-9 into every row, column and 3x3 box. Killer: Digits in cages do not repeat and sum to the number in the top-left corner. Arrows: Digits along an arrow sum to the number in the bulb. Palindromes: digits along a line (with no bulb/arrows) read the same sequence forwards and backwards.
Good Luck!
Solution code: Row 9-left to right

It felt very carefully crafted - excellent puzzle.

Great puzzle! I don't know if I would have solved the tricky break-in without a hint from Mark on CTC today. (I didn't actually need the details, just to be reminded to try a certain something...)
I do prefer the presentation they used in the video, with regular sized arrow bulbs, and lines that are easier to tell apart. Though I like the blue color here.

Nice setting. Still a lot of work after the break-in for me. Thank you!
