The answer to both points: the universe exhibits, as far as we can tell, a high degree of correctness. We've already tested it in pretty diverse and extreme circumstances and found it consistent. Clearly if our universe is a simulation, the simulators are both willing and able to give a shit about correctness, enough that there's no reason they would use the shoddy engineering that plagues modern attempts at sandboxing. The cut-rate simulations humanity is or will be capable of anytime soon are irrelevant.
