The review desk is the human in the vault. Every graded role arrives here, and every role leaves as one of three decisions: submit it, send it back to be fixed, or kill it. Nothing reaches an employer without passing through that judgement, and the desk is the reason the autopilot upstream is capped rather than free.
The desk exists because of one thing a loop can never do for itself: decide whether its own target is the right target. The sourcing autopilot can grade a role against fixed criteria, but it cannot know whether this particular role, this week, is worth a person's time. That call belongs to the slower loop that owns the faster one, and the slowest loop here is a human.
The desk also refuses to grade a pack by its own drafting. A pack is judged against something independent of the process that wrote it, so density of the right keywords never gets to stand in for substance. What the human accepts, edits or rejects at this desk is the signal that feeds the learning loop; the desk is where ground truth enters the system.
