§ The result
Greenhouse leads Arena Analytics on all 7 criteria.
Rubric v1.0 puts 35 points between Greenhouse (ATS-integrated) and Arena Analytics (Screening): 67 (D) for Greenhouse, 32 (F) for Arena Analytics. Greenhouse leads every one of the 7 criteria and 6 of them by 20 raw points or more, Bias Audit Transparency among them; Arena Analytics leads none. The advantage Greenhouse holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Arena Analytics 25, Greenhouse 86, 18% weight), yet it supplies only 31% of the weighted points Greenhouse gains across the 7 criteria it leads.

2.1 weighted points to Greenhouse
Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -35.5 — the difference between the two totals before either is rounded. Shares are of 35.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -35 beside that -35.5.

§ 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.
