Adjudication desk for contradictory data

When your sources disagree, see both sides before you pick one.

A knowledge base quietly contradicts itself all the time. Load a real entity, put every competing claim side by side with its references, and rule on which one governs with an explainable precedence engine. The ruling is sealed into a hash chain, so anyone can replay it.
