Two remortgage cases, one clean and one where every fact checks out on its own and the facts still contradict each other as a whole. An AI underwriting agent is about to approve both. You run each case, watch Sheaf measure whether the reasoning holds together, and decide what happens to the one it halts.
This walkthrough is scripted so that it plays the same way every time. The case shapes are real; the second is reconstructed from a published Financial Ombudsman decision. To see Sheaf do this on a live agent with real tools, run one for real afterwards.
