§ The result
Ribbon leads Aon Assessment on all 7 criteria.
Under rubric v1.0, Ribbon, filed under Screening, finishes on 43 and Aon Assessment, filed under Assessment, on 35, 8 points apart. Ribbon takes all 7 criteria from Aon Assessment without a 20-point raw gap on any of them; the closest is Article 11 Technical Documentation, Aon Assessment 40 to Ribbon 42. The advantage Ribbon holds is spread out: Data Governance Disclosure is both the widest raw gap and the heaviest weighted swing (Aon Assessment 38, Ribbon 50, 15% weight), yet it supplies only 22% of the weighted points Ribbon gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -8.3 — the difference between the two totals before either is rounded. Shares are of 8.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -8.3.

§ 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.
