§ The result
Greenhouse leads Mercor on all 7 criteria.
Rubric v1.0 puts 44 points between Greenhouse (ATS-integrated) and Mercor (Screening): 67 (D) for Greenhouse, 23 (F) for Mercor. Greenhouse is ahead of Mercor on all 7 criteria, every one of them by 20 raw points or more. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Greenhouse 86, Mercor 10, 18% weight), but it accounts for only 31% of the weighted advantage Greenhouse 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 +43.8 — the difference between the two totals before either is rounded. Shares are of 43.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +44 beside that +43.8.

§ 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.
