§ The result
Greenhouse leads impress.ai on all 7 criteria.
Rubric v1.0 puts 29 points between Greenhouse (ATS-integrated) and impress.ai (Screening): 67 (D) for Greenhouse, 38 (F) for impress.ai. Greenhouse leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; impress.ai leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Greenhouse 86, impress.ai 22, 18% weight), but it accounts for only 39% 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 +29.3 — the difference between the two totals before either is rounded. Shares are of 29.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +29 beside that +29.3.

§ 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.
