§ The result
3 points separate Factorial and Ribbon.
Factorial holds a 3-point edge over Ribbon under rubric v1.0, 46 to 43, across the ATS-integrated and Screening cohorts. Factorial leads 6 of the 7 criteria, including Article 11 Technical Documentation, while Ribbon leads 1, including Bias Audit Transparency. Bias Audit Transparency is at once the widest raw gap and the heaviest weighted swing, and it belongs to Ribbon — Factorial 25, Ribbon 38, on an 18% weight — which is 100% of the weighted advantage Ribbon holds across the 1 criterion on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +2.9 — the difference between the two totals before either is rounded. Shares are of 7.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +2.9.

§ 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.
