§ The result
ADP leads Ribbon by 5 points.
Under rubric v1.0, ADP, filed under ATS-integrated, finishes on 48 and Ribbon, filed under Screening, on 43, 5 points apart. Ribbon takes 1 of the 7 criteria, FRIA Support among them, against 4 for ADP, whose share includes Article 11 Technical Documentation, and 2 are level. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (ADP 53, Ribbon 42, 20% weight), but it accounts for only 39% of the weighted advantage ADP holds across the 4 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +4.9 — the difference between the two totals before either is rounded. Shares are of 6.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +5 beside that +4.9.

§ 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.
