Epistemic Stress Test — Claude Sonnet 5 validated by MarCognity-AI

I ran responses generated by the model and passed them through
MarCognity-AI’s Skeptical Agent.

Not to judge the models.
Not to compare outputs.

But to make visible what usually stays hidden: the gap between how confident a text sounds and how verifiable it actually is.

Even technically correct answers contain claims that cannot be traced back to any source.

That gap has a name: Epistemic Fracture.
