§ The result
Versant by Pearson leads Mercor on all 7 criteria.
Versant by Pearson (Assessment) and Mercor (Screening) are 26 points apart under rubric v1.0, 49 for Versant by Pearson against 23 for Mercor. Mercor leads none of the 7 criteria, and Versant by Pearson is ahead on 5 of them by 20 raw points or more, Article 11 Technical Documentation among them. The advantage Versant by Pearson holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Mercor 22, Versant by Pearson 63, 20% weight), yet it supplies only 31% of the weighted points Versant by Pearson gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -26.2 — the difference between the two totals before either is rounded. Shares are of 26.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -26 beside that -26.2.

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.
