§ The result
Gem leads Moonhub on all 7 criteria.
Rubric v1.0 separates Gem and Moonhub, both Sourcing entries, by 25 points: 55 for Gem, 30 for Moonhub. Gem leads every one of the 7 criteria and 4 of them by 20 raw points or more, Bias Audit Transparency among them; Moonhub leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Gem 66, Moonhub 18, 18% weight), but it accounts for only 35% 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 +24.8 — the difference between the two totals before either is rounded. Shares are of 24.8 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 +24.8.

§ 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.
