What a certificate is actually worth
Delivering AI-assisted work increasingly means being asked, months later, who reviewed it and what they checked. A chat message saying "we looked it over" answers neither question. A certificate carries the pieces a reviewer needs to trust the claim: the draft it covers, the person who signed it, the timestamp, the rules that were enforced, and the claims with the sources they were checked against.
That last part matters most. The certificate does not just assert that checking happened, it lists what was checked, so a reader can spot the claim they disagree with and see which source was recorded for it. It is a record of process, which is what procurement, legal and compliance teams are actually asking for.
