The evidence check

Whether there is evidence for the link, and of what kind.

The part

What it is

A link with no evidence is a hypothesis. That is a legitimate state, provided it is labelled and tested rather than repeated until it sounds settled.

This element is what connects the value map to the proof module, and it keeps the two from drifting apart.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
