Verify a factual claim against multiple live web sources (Brave). Returns a JSON object with a verdict (supported / contradicted / unverified), a 0-1 consensus score, short reasoning, and the actual cited sources (ref, title, url). Judges only from retrieved sources — never fabricates. 'contradicted' is used only when sources actively assert the opposite; absence of evidence yields 'unverified'.
