Here's a tatamibari-sudoku hybrid!
Rules:
Normal sudoku rules apply. Adjacent digits on a green line differ by 5 or more.
Divide the grid into rectangular regions so that each region contains exactly one killer clue. Four regions cannot share the same corner. Digits may not repeat within a region and sum to the killer clue. The digit placed in a cell containing a killer clue gives information about that region:
1–4: The region has a greater width than height.
5: The region is a square.
6–9: The region has a greater height than width.
Solve online:
Lösungscode: Column 2 (top to bottom, 9 digits, no spaces)

Original puzzle, fun to solve. I don't think I used the 4-corners anywhere. Thanks :)

A quick clarification. Can there be cells which are not part of any region? Do ?s stand for any number or only single digit numbers? if the entire grid is covered by regions, then I think they are any numbers. In that case, wouldn’t * be a better notation?
---------
Every cell belongs to exactly one region. "?" represents any number.

Quick rules clarification question, do killer clues have to appear in the top left cell of their cage?

Thanks! Sorry, I wasn't sure reading the rules at work, when I got home and started it that became apparent very quickly.

Beautiful puzzle. I didnt get to use the 4 corner constraint but probably somewhere it could have made life easier for me while solving.
