Fillomino. Each clue is replaced with a letter, which stands for a number. Different letters represent different numbers, and the same number is represented by the same letter. In addition, there is exactly 1 false clue in each row/column.
Once again, a ridiculously hard puzzle. Partially due to this ridiculously ambiguous variant.

I always enjoy Liar as a variation, and Fillimino is my favorite type to see varied. I haven’t encountered this particular combination successfully attempted anywhere else, and you’ve executed it really well – thank you for making such a great puzzle.
