§ The result
Alva Labs leads Ribbon on all 7 criteria.
Under rubric v1.0, Alva Labs (Assessment) opens an 18-point lead on Ribbon (Screening), 61 (D) to 43 (F). Of the 7 criteria Ribbon wins none, and the narrowest lead Alva Labs holds is on FRIA Support, Alva Labs 38 to Ribbon 33. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Alva Labs 78, Ribbon 42 — and at a 20% weight it carries 40% of the weighted advantage Alva Labs 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 +17.8 — the difference between the two totals before either is rounded. Shares are of 17.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +18 beside that +17.8.

§ 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.
