§ The result
2 points separate Arena Analytics and Cognisess.
Arena Analytics holds a 2-point edge over Cognisess under rubric v1.0, 32 to 30, across the Screening and Assessment cohorts. The criteria split evenly, 3 each to Arena Analytics and Cognisess, with 1 level, and the weighted points on the side Arena Analytics holds, headed by Article 11 Technical Documentation, settle the total. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Arena Analytics 30, Cognisess 25, 20% weight), but it accounts for only 38% of the weighted advantage Arena Analytics holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +1.5 — the difference between the two totals before either is rounded. Shares are of 3.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +1.5.

§ 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.
