§ The result
X0PA AI leads Mercor on all 7 criteria.
Rubric v1.0 puts 25 points between X0PA AI (Assessment) and Mercor (Screening): 48 for X0PA AI, 23 for Mercor. X0PA AI leads every one of the 7 criteria and 5 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, X0PA AI 44, 18% weight), but it accounts for only 24% of the weighted advantage X0PA AI 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 -25.3 — the difference between the two totals before either is rounded. Shares are of 25.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -25 beside that -25.3.

§ 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.
