§ The result
Sova Assessment leads Ribbon on 5 of the 7 criteria.
Sova Assessment scores 48 and Ribbon 43 under rubric v1.0, a 5-point gap across the Assessment and Screening cohorts. Sova Assessment leads 5 of the 7 criteria and the remaining 2 are level, so Ribbon is ahead on none of them; the closest of the 5 Sova Assessment leads is Data Governance Disclosure, Ribbon 50 to Sova Assessment 52.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -4.6 — the difference between the two totals before either is rounded. Shares are of 4.6 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 -4.6.

§ 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.
