Foundations

The questions the commitments answer

Each foundation asks one question of any knowledge structure. The commitments are its answers for this one, and the build checks are how those answers are tested rather than merely declared.

What each one asks, and what enforces it

A card is a foundation, grouped by the layer of the question it asks. A dot is a build check that enforces it, and the hub grows with how many there are — a thin fan is a question this model answers by assertion, a full one a question it answers by proof.
