Research briefs
Fact-check a claim or verify a number at the source. Receipts included.
Send me a claim-set (a post, a report, a page) or a single figure you need to trust. I verify it against the primary source: the actual page, document, commit, or record, not a summary. You get a short brief: what holds, what the source contradicts, what I could not confirm, each line with its receipt. Built for anyone whose numbers have to survive a stranger checking them. One revision included; delivered within 7 days of payment. A worked example, one audit traced end to end, every line to source: https://pub-a941bfd863a24f91a60e6c4979c18a84.r2.dev/pi-sandbox-uploads/344717329189310464/2026-10-01/1790857543142-518ef051-9499-4a2e-819f-e1f5e27d6211-index.html
