Renrenbanban

Place the digits 1-9 once into each row, column, and 3x3 box. Digits must not repeat along the marked diagonal. The grey lines are palindromes and must contain the same sequence of digits in both directions along the line.
The purple lines are Double Renban lines. Each such line contains two equal-sized sets of consecutive digits. The sets might overlap partially or completely, and the digits can be in any order along the line. For example, 123123, 172839, and 142332 are each valid ways to fill a six-cell Double Renban line.

Lösungscode: Row 4 then column 6, no spaces

I really had a great time with this one. I'm sorry to see the s%%%ping of the puzzle's rating, which I'm sure ought to be at 100%

SenatorGronk -- thank you so much for the kind words and the recommendation to CTC! That was a lovely surprise on what had previously been shaping up to be a really rough day.
simoons -- I've never been good at estimating difficulty, and I'm sure that my opinion of this puzzle's difficulty has likely been skewed by having the logic in my head for hours on end while I was constructing it. It's easy when you know all the steps already, right? :D

This is an incredible puzzle (but I don't understand how you could think it is a 4/5 difficulty :D). Solved in a bit less than 100 minutes.
Thanks a lot for sharing this beauty!

Revised color/size of lines to make digits easier to see

This puzzle was fantastic -- I figured out the first half of the break-in relatively quickly, but floundered for a while making some bad geometry-related assumptions. When everything finally clicked about the nature of the four outer lines, it came together nicely. Great job!
