Prompt

Inputs: [NEWS CLAIM], [LINKED REPORT], [DATA TABLE]. Find the underlying table and reproduce the stated number if possible. Note period, geography, denominator and revisions. Output: A calculation trail, discrepancy table and cautious conclusion. Check: No number is accepted solely because it appears in a headline. If essential information is missing, identify it rather than filling the gap with a guess. Keep the original headline wording beside the reconstructed calculation for direct comparison.
