Who is Rodd Stevens?

I still don't know the answer to this question, but 99%Sneaky must, as that's the title of today's puzzle. I made this puzzle look quite hard but I suspect that you'll have an easier time with it than I did. It makes excellent use of a disjoint region.

RULES:
Normal sudoku rules apply.
The pink circles contain a complete set of the digits 1 through 9. If the digit in a pink circle is on one of the following line types it counts the number of parity changes [i.e. from odd to even or vice versa] between adjacent digits which occur along that line.
LINE TYPES:
The digits along the dark blue line sum to 5. Adjacent digits along the green line must have a difference of at least 5. The grey line is a palindrome and and must read the same in both directions. Digits on the turquoise thermometer must increase from the bulb end to the tip. Digits along the red double arrow have the same sum as the digits in the attached circles. Every string of three adjacent digits along the yellow line must contain one digit from each modulo 3 set: 147, 258 or 369. Digits along the lilac line form a set of non-repeating consecutive digits in any order.
Note: Lines do not share cells, branch or overlap.
Additionally, the grid is partially covered in fog and placing correct digits will clear the fog from the surrounding cells. Guessing is not required.

Great puzzle. Looks impossible but isn't. Love Fog.

This puzzle is so much fun!

I actually have some insight into this puzzle, or at least a part of it - this is an entry in a series involving a "Sudoku chain letter", where a previous setter passes along a grid containing cells as a disjoint set (a complete set of the digits 1-9). I made the first grid, created a puzzle and then passed a new grid along to Marty Sears who made "Counting Castles"; who passed along a new grid to Heliopolix, who made "Derezzed"; who then passed along the layout for the circles here to 99%Sneaky. I'm so happy to see this is still going! and I'm very keen to find out who the next mystery setter will be.
As for the puzzle itself, having helped to test this I can vouch for its quality - give this a go! There are some really brilliant parts to this, involving both the disjoint set as well as the Parity Lot constraint. Great fun to be had here.

I wondered if this was part of that lineage

Around 17:45, you were so close to getting the 6 in r5c5...
If r5c5 is 8, you get 8 in r4c2, and 8 in r7c4. But you also get an 8 in r3c4.

[@puzzlepusher]

Yes that’s the logic I missed for 20 minutes or so 🤦

[@mscha]

At 27:48, I don't see why you conclude that r4c7 must be 4 or 5. Aren't 2 or 3 still an option?
(They aren't because r7c5 is 2 or 3 - the line isn't long enough for a 4.)

Hi, welcome, I make mistakes quite a bit 😬
I have no idea what I was thinking at that point. Probably got so excited to discover the 5 logic that I forgot to look lower. I’m sure in hindsight that the intention was to discover the 23 circles pair first but obviously I didn’t have that yet, though the logic to place the 6s was available and I don’t think I ended up using that 4 or it’s reveal for anything before finding it

Fantastico! Thanks for the feature!
(Cheers from 99%Sneaky 🥸)
Very lovely logic using the unrhymable colors to unwind the palindrome 🧡💜 That line is for sure the crux of the puzzle and you dealt with it very well.

[@puzzlepusher]

I appreciate you saying so (even though I know it’s not true 😂)
