§ The result
Braintrust AIR leads Jack & Jill on all 7 criteria.
Braintrust AIR, filed under Screening, comes out 10 points above Jack & Jill, filed under Sourcing: 59 against 49 under rubric v1.0. Braintrust AIR takes all 7 criteria from Jack & Jill without a 20-point raw gap on any of them; the closest is Human Oversight Design, Braintrust AIR 62 to Jack & Jill 58.
