§ The result
Pillar leads Mercor on all 7 criteria.
Pillar finishes 17 points clear of Mercor inside the Screening cohort under rubric v1.0: 40 against 23. Pillar leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; Mercor leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Mercor 10, Pillar 38, 18% weight), but it accounts for only 30% of the weighted advantage Pillar holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -17.1 — the difference between the two totals before either is rounded. Shares are of 17.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -17 beside that -17.1.

§ 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.
