Part 2 of the Epistemic AI series. In Part 1, we defined the problem: AI tools don't track what they know. Here, we make it measurable. When we talk about "what the AI knows," we're not being metaphorical. Knowledge has structure, and that structure is measurable — not perfectly, but well enough to catch the failures that matter.
