Substantial gaps
Screening
The result
Greenhouse leads Ribbon on all 7 criteria.
Under rubric v1.0, Greenhouse (ATS-integrated) opens a 24-point lead on Ribbon (Screening), 67 (D) to 43 (F). Ribbon leads none of the 7 criteria, and Greenhouse is ahead on 3 of them by 20 raw points or more, Bias Audit Transparency among them. The advantage Greenhouse holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Greenhouse 86, Ribbon 38, 18% weight), yet it supplies only 37% of the weighted points Greenhouse gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +23.6 — the difference between the two totals before either is rounded. Shares are of 23.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +24 beside that +23.6.

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.
