Could you build this?
No Deterministic simulation that can verify arbitrary mission-critical systems requires controlling nondeterminism at the runtime and OS level, which is specialized distributed-systems research engineering.
What it would actually take: A real version requires a deterministic runtime that controls time, scheduling, I/O, and randomness for the system under test, plus fault injection and state-space exploration. This takes expert distributed-systems and verification engineering, comparable to FoundationDB-style simulation.
