§ The result
Braintrust AIR leads Pillar on all 7 criteria.
Under rubric v1.0, Braintrust AIR opens a 19-point lead on Pillar, 59 to 40, with both scored in the Screening cohort. Braintrust AIR leads every one of the 7 criteria, Pillar none of them, and the closest of the 7 is FRIA Support, Braintrust AIR 35 to Pillar 30. The advantage Braintrust AIR holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Braintrust AIR 75, Pillar 38, 18% weight), yet it supplies only 36% of the weighted points Braintrust AIR gains across the 7 criteria it leads.

Shares are of 18.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +19 beside that +18.5.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
