§ The result
Xobin leads Ribbon on all 7 criteria.
Xobin scores 50 and Ribbon 43 under rubric v1.0, a 7-point gap across the Assessment and Screening cohorts. Xobin takes all 7 criteria and Ribbon none of them; the nearest contest is Post-Market Monitoring, Ribbon 37 to Xobin 38. One criterion, Article 11 Technical Documentation, is both the widest raw gap (Ribbon 42, Xobin 62) and the heaviest weighted swing, and at 20% weight it makes up 58% of the weighted advantage Xobin holds across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -6.9 — the difference between the two totals before either is rounded. Shares are of 6.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -7 beside that -6.9.

§ 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.
