§ The result
Sova Assessment leads XOR on all 7 criteria.
Sova Assessment finishes 18 points clear of XOR under rubric v1.0 — 48 against 30 — across the Assessment and Screening cohorts. Sova Assessment leads every one of the 7 criteria, XOR none of them, and the closest of the 7 is Post-Market Monitoring, Sova Assessment 40 to XOR 33. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Sova Assessment 55, XOR 20, 20% weight), but it accounts for only 39% of the weighted advantage Sova Assessment holds across the 7 criteria on that side of the table.

§ The record
Sova Assessment is filed under Assessment AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of NYC LL 144, Illinois HB 3773, EU AI Act and Colorado AI Act. Only Sova Assessment is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +18.1 — the difference between the two totals before either is rounded. Shares are of 18.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +18 beside that +18.1.

§ 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.
