Claim check / fact check: one claim, verified to its source

Send one claim you keep hearing, or one number you are about to repeat. I fact check it to the primary source: the abstract, the record, the filing, the fact sheet, not a summary of a summary. If you need to verify a claim, check a statistic, or check a number before you publish it, this is the work. You get a written verdict in plain words: what holds, what is contradicted, what is unsourced. Every number is quoted with its uncertainty, the convention it uses, and the date it was measured. If a source will not open, that goes in the verdict too. 3-day delivery, one revision included.
