I had renamed `kernel_invalid_bounds_0_8` with `called_from_invalid_bounds_1` since bounds [0,8] are no longer invalid. That's arguably a pretty non-sensical name for this and I can't remember why I picked this, so I will rename it.

Yes that is expected, though it's missing an attribute/accompanying CHECKs. Will address that as well.
