Rules:
Fillomino - Divide the grid into regions and fill each cell with the size of the region (in number of cells). Regions of the same size cannot share a cell edge. One region border (between R10C8 and R10C9) is given.
Reverse Counting Circles - A number appearing in a circle indicates how many times that number appears *outside* of circles. (There is no limit on numbers that never appear in circles.)

I hope you enjoy the puzzle! :-)
Solution code: For columns 3 and 9, enter the number of sequential cells in each region. Use no delimiter for regions and a dash - for columns, e.g., 2234-222122

This had some beautiful logic, and the play between numbers needing to be in or to avoid circles was very clever. Enjoyed this a lot.

This is a really inventive approach, set up beautifully by some deft cluing. Not having seen the Simon solve you referenced, it took me a minute to really understand the reverse counting principle, but once I did i really appreciated how solid the flow was here. Great puzzle, thank you!!

That was absolutely fantastic fun. Really novel logic and a great flow. I thought I'd broken it a couple of times (including trying to enter the solution code) but it always turned out that there was another possibility I'd overlooked. Looking forwards to the next one!
