§ The result
Ribbon leads Cognisess on all 7 criteria.
Ribbon sits 13 points above Cognisess under rubric v1.0 — 43 against 30 — with Ribbon filed under Screening and Cognisess under Assessment. Ribbon is ahead of Cognisess on all 7 criteria but on none of them by as much as 20 raw points, the closest being Post-Market Monitoring at Cognisess 32 to Ribbon 37. Bias Audit Transparency is the widest raw gap (Cognisess 20, Ribbon 38) but not the heaviest weighted swing, which is Article 11 Technical Documentation at 20% (Cognisess 25, Ribbon 42), 25% of the weighted advantage Ribbon builds across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -13.4 — the difference between the two totals before either is rounded. Shares are of 13.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -13 beside that -13.4.

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.
