I don’t know about their process, but if I was in charge of such work, I would create a replica system to mimic the response without the wait, and the risks, it might not eliminate all of them, but definitely will minimize them.

There are replicas but there may also be differences because of the large amount of human effort required to build one. I saw a replica complete with wire-wrapping over a decade ago. This technology looks very foreign to any recent computer engineer. As such, the more practical approach is to write software that can validate most commands you would send. I wonder what level of emulation they have achieved (if any) on modern hardware.

Replicating the bits of hardware destroyed by radiation in the correct place and to the correct degree may be bit tricky.
