I think this is a 2-star puzzle if you are familiar with the 159 logic. It might be more challenging if you're not. Feel free to let me know what you think about the puzzle or the puzzle name (did you get it?). Enjoy!
Rules:
Normal sudoku rules apply.
159: Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if R2C1 is a 4, R2C4 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9 respectively.
Killer: Digits in cages must not repeat, and sum to the small number in the top left corner of the cage.
Palindrome: Digits on a grey line must read the same from both directions (e.g. R9C5 is the same digit as R7C7).
Solution code: Column 3 digits from top to bottom.

159 expertise required - then the solution flows smoothly, albeit requiring considerable effort.

I had to brute force it a couple of times, but I'm rather new to the 159 rule. Lovely puzzle, I enjoyed the killer boxes restrictions mixed with the palindromes.

This is a very clever and enjoyable puzzle! I think a 2-star rating is probably too low. There were two points at which the solution path became narrow and required specific deductions to be made in order to progress. But I loved the setting overall!
