§ The result
Saville Assessment leads Ribbon on 6 of the 7 criteria.
Under rubric v1.0, Saville Assessment, filed under Assessment, finishes on 48 and Ribbon, filed under Screening, on 43, 5 points apart. Ribbon is ahead on none of the 7 criteria: Saville Assessment takes 6, the remaining criterion is level, and the nearest of those 6 is Post-Market Monitoring, Ribbon 37 to Saville Assessment 38. The advantage Saville Assessment holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Ribbon 42, Saville Assessment 50, 20% weight), yet it supplies only 36% of the weighted points Saville Assessment gains across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -4.4 — the difference between the two totals before either is rounded. Shares are of 4.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -5 beside that -4.4.

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.
