§ The result
Greenhouse leads Willo on all 7 criteria.
Rubric v1.0 puts 26 points between Greenhouse (ATS-integrated) and Willo (Video interview): 67 (D) for Greenhouse, 41 (F) for Willo. Greenhouse leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; Willo leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Greenhouse 86, Willo 30, 18% weight), but it accounts for only 38% 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 +26.2 — the difference between the two totals before either is rounded. Shares are of 26.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +26 beside that +26.2.

§ 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.
