§ The result
Ribbon leads Moonhub on all 7 criteria.
Ribbon sits 13 points above Moonhub under rubric v1.0 — 43 against 30 — with Ribbon filed under Screening and Moonhub under Sourcing. Ribbon leads every one of the 7 criteria, Moonhub none of them, and the closest of the 7 is Human Oversight Design, Moonhub 48 to Ribbon 55. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Moonhub 18, Ribbon 38, 18% weight), but it accounts for only 28% of the weighted advantage Ribbon 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 -12.9 — the difference between the two totals before either is rounded. Shares are of 12.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -13 beside that -12.9.

§ 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.
