Completion is not acceptance. A draft can be finished and still not be ready to send. Hypothetical example: an assistant at a small agency asks an AI tool to draft a client proposal from last quarter's template. Moments later it's done: right logo, right sections, right tone. She skims it, feels the relief of a task off her plate, and almost sends it.
Then she notices the pricing table. It's last quarter's pricing. The draft is complete. It's also wrong.
Nothing malfunctioned. The draft was built from the template it was given, and the current price list wasn't part of the brief. Whether this proposal, with these numbers, goes to this client is a sign-off decision, made by a person, after the drafting.
