What you're saying is that "creating a tool requires validation, but not creating a tool and winging it doesn't." Which is engineering-speak ridiculous. To debug anything you need a mental model of the thing in question. With that mental model you can build a software-based model of it (a simulation), you can document it, or both. But for some reason you believe that documentation doesn't require validation, but the tool that expresses a model represented by the documentation does not. Realistically speaking, they have 2 days between command and response, so they have plenty of time to write a simulator.
