Which sanity failure did you receive on this invariant?
I couldn't find a link to a failing job here:

would also like to know what was wrong with the invariant, it looks ok and we still want such invariants. do you have a link to the original spec with the sanity failures

Is sload now defined nowadays, so is this why we see the sanity failure for trivial post condition of the invariant?

what was the sanity failure? we prefer invariant as the requireinvariant is safer
