Abstract
We introduce bounded category forcing axioms for well-behaved classes . These are strong forms of bounded forcing axioms which completely decide the theory of some initial segment of the universe modulo forcing in , for some cardinal naturally associated to . These axioms naturally extend projective absoluteness for arbitrary set-forcing--in this situation --to classes with . Unlike projective absoluteness, these higher bounded category forcing axioms do not follow from large cardinal axioms, but can be forced under mild large cardinal assumptions on . We also show the existence of many classes with , and giving rise to pairwise incompatible theories for .
