Petit test
Guess first, no penalty. An AI tool ranks 80 applicants and marks 60 "not a fit". What should happen before any of them gets a rejection email?
A human decision means a named person looks at the result and decides, not just clicks "approve all". A paper trail is the written record of what was checked, by whom and when.
The record matters when someone asks why a person was turned down: a candidate, your manager, an auditor or a regulator. "The tool said so" won't satisfy any of them.
