Chaos Construction: Corridors
Inspired by Jovi_al's fantastic Framed Chaos, this is my take on the Chaos Construction category. It has been an adventure to set, and I hope it will be an equally exciting adventure to solve! Happy new year!
Rules:
- Normal irregular sudoku rules apply: The digits 1-9 must appear once in every row, column and region.
- A region is an orthogonally connected set of 9 cells.
- The regions' shape and location must be determined by the solver.
- A region can not contain a 2x2 block of cells.
- The numbers outside the grid show the sum of the digits up to the next region border in that row or column.
- An arrow indicates a horizontal or vertical corridor of cells of length N within a region, where N is the digit in that cell.
Note: f-puzzles and the CTC app don't support solution checking for this kind of puzzle, so you should disable "conflict checking". The penpa version will correctly verify the solution.

Solution code: Rows 5 and 6, with an added hyphen between the rows and also for each region border. (For example "123-45-678-9-12345-6-7-89")

I am pretty new to solving these chaos constructions and this one is just a wonderful! Really neat logic and very consistent difficulty. Awesome job!

Nice and tight logic, but I made a late-game mistake, couldn't find it and had to restart. :(

A successful first attempt on chaos construction. Very pleasant solving in the construction phase, a nice interaction with one of the smaller digits to claim the last borders. The resulting chaos sudoku was an easy solve.
Thanks
