Agent-readable context should preserve the public boundary.
The richer layer is not permission to guess.
It is a way to be more precise about what is public.
That means the structure should help an agent understand the notes, themes, routes, source trails, and open questions.
It should also say what not to infer.
The boundary is part of the interface.
Without it, a helpful agent can become too confident.
With it, the site can be more useful without pretending to be total.
Good public context should make better introductions possible.
It should not collapse the whole person into the public record.
