Two remortgage cases. One is clean. In the other, every fact is correct on its own, but the facts contradict each other when put together. An AI is about to approve both. You run each case, watch Sheaf check whether the reasoning holds together, and decide what happens to the one it stops.
This walkthrough is scripted, so it plays the same way every time. The cases are based on real ones. The second is rebuilt from a published Financial Ombudsman decision. To see Sheaf do this on a live AI agent, run one for real afterwards.
