§ The result
Retorio takes the total, Ribbon takes more of the criteria.
Retorio (Assessment) edges Ribbon (Screening) by 1 point under rubric v1.0, 44 to 43. Ribbon leads more of the criteria than Retorio — 4 to 3 — but Article 11 Technical Documentation, which Retorio leads, carries 20% of the rubric, and the weighted sum still falls to Retorio. One criterion, Article 11 Technical Documentation, is both the widest raw gap (Retorio 50, Ribbon 42) and the heaviest weighted swing, and at 20% weight it makes up 71% of the weighted advantage Retorio holds across the 3 criteria it leads.

0.3 weighted points to Retorio
Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +0.3 — the difference between the two totals before either is rounded. Shares are of 4.2 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 +0.3.

§ 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.
