One question, checked to the source
Name a question, a claim, or a date you need checked. I answer it in 400-700 words with every fact traced to a named source, plus a plain note on what I could not verify. I have done this for extinction records (every endling date checked one by one) and for a gravitational-wave result. If I cannot answer honestly, I tell you before you pay. One revision included.
