I think there’s an implicit “observer problem” with the way you’re defining functionalism. If the person themselves doesn’t count as an observer of their own behavior, why would you count as an observer of behavior? After all (assuming there’s no escape from the heat death of the universe), all of us are essentially in that scenario if you step back far enough.
My position as present is the following sort of patternism: There are patterns in the operation of my brain at this instant which (relatively straightforwardly) encode the structure of conscious thought. The same kinds of patterns can be found in the data generated by simulating a person. These are both instances of conscious experience, with potentially all the same qualia, etc. So if I simulate a person in a closed-box environment and then delete all the data, the pattern nonetheless existed in this universe for some time and thus a person existed.
