Why use a tiered human review structure instead of one flat pool of annotators?
Most annotation cases are routine and can be handled quickly by trained core annotators applying consistent standards. A minority are genuinely ambiguous or subjective and need deeper judgment. Routing the easy majority to a fast first-pass tier and escalating only the hard cases to expert reviewers keeps both throughput and quality high, instead of forcing every case through the same expensive, slow review path.
