Yeah, but this is the morally right approach to write-only information. We should think of the cleaner interface for accumulating stuff, like warnings and accesses, but this is still a close approximation to it. This is at least the right place where resets should happen for the accesses. |

Would we not still need some special logic to account for side-effects from things that are superstable?

Possibly. When I later thought about it, I was confused about that too, but it somehow works on all the incremental tests we have.
Maybe this is completely broken after all...

This is on top of #391.
I'm not proud to present this hack to restart incremental accesses only during postsolving. This (hopefully) works for the same reason incremental warnings work, but instead of a new generic interface this is the crudest possible way to achieve the same. No guarantees!
