The archive should let agents inspect without making humans navigate everything.
Those are different jobs.
An agent can handle the full index.
It can scan dates, tags, source trails, and related routes.
It can compare old language to current language.
A person probably does not want that as the first experience.
They need a doorway.
Then another.
Then the option to wander.
The archive can be deep without making the human path dense.
That is the point of having layers.
