Sure; but we may also want to think about what may happen in the future.

I think I'd agree. I think there's a question of how to allow for processes of different quality. Do we require that mis must only be used after a correct analysis, or allow it to be used after analyses that may be erroneous? E.g., if a process is not able to recognize some edge-case usage of English and it instead concludes that the content is Romulan, hence there's nothing in the LSTR to support that lang, then is it acceptable to declare mis? (The process may not make the correct analysis, but one might argue that, modulo its abilities, that's the appropriate result.)

Certainly if a process is unable to reach any conclusion -- it didn't complete an analysis or its analysis gave ambiguous results, that's when und would be appropriate.
