Your idea for "angels-on-the-shoulder" as part of the epistemic stack addresses a critical legibility requirement for any information system. Power users may dive into adjacent information and consolidate understanding with reference material, but the vast majority of users will be passive, not active. Even power users are likely to be active only in domains where they believe they have outsized insight, and only when they have time to devote to doing epistemic work. Have you considered what the incentive structure looks like for the power users who do the epistemic work that passive users rely on? The angels need to eat.
