§ The result
2 points separate Ribbon and Willo.
Ribbon holds a 2-point edge over Willo under rubric v1.0, 43 to 41, across the Screening and Video interview cohorts. Ribbon leads 5 of the 7 criteria, including Bias Audit Transparency, while Willo leads 2, including Human Oversight Design. The advantage Ribbon holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Ribbon 38, Willo 30, 18% weight), yet it supplies only 37% of the weighted points Ribbon gains across the 5 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +2.6 — the difference between the two totals before either is rounded. Shares are of 5.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +2.6.

§ 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.
