§ The result
Gem leads Cognisess on all 7 criteria.
Rubric v1.0 puts 25 points between Gem (Sourcing) and Cognisess (Assessment): 55 for Gem, 30 for Cognisess. Gem leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; Cognisess leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Cognisess 20, Gem 66, 18% weight), but it accounts for only 33% of the weighted advantage Gem holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -25.2 — the difference between the two totals before either is rounded. Shares are of 25.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -25 beside that -25.2.

§ 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.
