§ The result
1 point separates Ribbon and Tengai.
Within the Screening cohort, Ribbon edges Tengai by 1 point under rubric v1.0, 43 to 42. The 7 criteria split 4 to 2 in favour of Ribbon, with 1 level: Ribbon is ahead on Bias Audit Transparency and Tengai on Article 11 Technical Documentation. The advantage Ribbon holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Ribbon 38, Tengai 33, 18% weight), yet it supplies only 38% of the weighted points Ribbon gains across the 4 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +1.4 — the difference between the two totals before either is rounded. Shares are of 3.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +1 beside that +1.4.

§ 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.
