If science were empirically complete and an entity could encompass all logical scope and complexity, what epistemological theory wins?

Science is "empirically complete" when it is well funded, all unknowns are constrained in scope, and (n+1) generations of scientists produce no breakthroughs of any kind.

If a hypothetical entity could encompass every aspect of science into reasoning and ground that understanding in every aspect of the events in question, free from bias, what is this epistemological theory?

I've been reading wiki articles on epistemology all afternoon and feel no closer to the answer in the word salad in this space. It appears my favorite LLM's responses reflect a similar understanding. Maybe someone here has a better grasp on the subject?
