Party chaos

Rules:
Normal sudoku rules apply,
The regions are to be deduced. Some region boundaries are given.
Clues outside the grid indicate the sum of the cells up until the first region boundary from that side. The last cell in the sum before the region boundary is of the other parity (odd/even) than all cells before it (from the side of the clue), a.k.a. Parity Party. This cannot be a single cell sum.
Clues also equal the sum of the digits sandwiched between the 1 and the 9 in the corresponding row/column. In rows/columns with outside clues those digits all belong to the same region and the 1 and 9 are not in that region.
Question marks can represent any positive integer value.
Along thermometers digits increase from the bulb end.
The digit in a grey square is even.
The digits separated by an X sum to 10 and are in the same region.
Try it here on Penpa Try it here on CTC
Lösungscode: Column 2, separate the regions with a - . e.g. : 123-45-678-9

Great puzzle ! Opening wasn't that hard for me, midsolve much more intricate though, with a lot of tiny steps around the center, pulling all kinds of CC tricks, until it finally cracked with a smooth ending. Enjoyed that ! Thanks :)
--Thank you!

Wow! That was super super hard for me! Even after the beautiful break-in, the mid-solve was so intricate. Felt like a 6-7 * for me. Would love to know the intended solve path. May be @Lizzy01 may share that as well in a hidden comment.
--Thanks! I'll think about doing that, but then I'd first have to solve it again myself. Fun fact: I started an early version of this puzzle a few years ago, but gave up on it when I couldn't get it to work the way I was trying at the time. Then recently I saw the screenshot in my computer and decided to use it for a new puzzle.

That was hard, but nice! it took me an embarrassingly long time to ask the right question at the beginning
--Thanks for solving!

Really nice puzzle. Difficulty felt like 5 stars to me.
--Thanks!

fantastic puzzle. Thanks. Nice opening moves to get the first few lines but getting quite hard in the midgame. The end flows smooth again.thanks.
--Thanks for solving!

@h5663454 I think having only a penpa option might reduce how many people try it too. But even then, it's weird how I see really good puzzles end up with so few solves. I reckon https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000IOI could use some more, too. ;)
I've created a sudokupad version of this puzzle to hopefully help with getting more attempts: https://sudokupad.app/71026el5xw
I was going to create one with a solution check, but I haven't solved it yet. I've struggled with it and made a couple of mistakes. I keep thinking I've broken it, then double-check/start typing out logic to prove it is broken, then discovering I've made an unjustified assumption about a piece of logic. I am really not doing the puzzle justice, because I'm pretty sure it is excellent.
And I've run out of time to do it right now, so will have to come back to it tonight/tomorrow.

Weird... Maybe the solving process to this puzzle is indeed a bit brutal, but no matter how difficult it is, I can't be the only one who has submitted it so far... It feels like someone’s prank...
--Yeah, I thought it was weird too. Thank you for solving it. There are a lot of my puzzles I spent a lot of effort on and get very few solves compared to some other ones.
