§ The result
Classet leads Ribbon on 5 of the 7 criteria.
Classet sits 12 points above Ribbon under rubric v1.0, 55 against 43, with both filed under Screening. Ribbon is ahead on none of the 7 criteria: Classet takes 5, the remaining 2 are level, and the nearest of those 5 is Article 11 Technical Documentation, Classet 46 to Ribbon 42. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Classet 76, Ribbon 38 — and at an 18% weight it carries 59% of the weighted advantage Classet holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +11.5 — the difference between the two totals before either is rounded. Shares are of 11.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +12 beside that +11.5.

§ 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.
