If we’re in a slow enough takeoff world, maybe it’s fine to just have the understanding standard here be post-hoc, where labs are required to be able to explain why a failure occurred after it has already occurred. Obviously, at some point I expect us to have to deal with situations where some failures could be unrecoverable, but the hope here would be that if you can demonstrate a level of understanding that has been sufficient to explain exactly why all previous failures occurred, that’s a pretty high bar, and it could plausibly be a high enough bar to prevent future catastrophic failures.
Another thought here:
