Human-in-the-loop is often described as a product feature: add a reviewer, add a button, add a final approval step. But meaningful human review is a governance position, not a decorative checkpoint.
The reviewer needs enough context to challenge the system. They need uncertainty, evidence, thresholds, and the authority to disagree. Otherwise the human becomes a liability shield for automated judgement.
Risk scores should support responsibility, not relocate it.
The human in the loop should be able to challenge the system.
