Human in the loop
A person who has to approve something before it happens.
The right idea, usually implemented as a rubber stamp. If the person sees fifty approvals a day with no context and no way to tell the risky one from the routine one, they are not supervision, they are latency. Human review works when it is reserved for the decisions that genuinely need judgment and arrives with enough context to exercise it.
Why it matters
A queue of approvals nobody can meaningfully review is worse than none, because it creates a record of consent.
