§ The result
Darwinbox takes the total, Ribbon takes more of the criteria.
Darwinbox (ATS-integrated) edges Ribbon (Screening) by 3 points under rubric v1.0, 46 to 43. Ribbon leads more of the criteria than Darwinbox — 4 to 2 — but Article 11 Technical Documentation, which Darwinbox leads, carries 20% of the rubric, and the weighted sum still falls to Darwinbox. One criterion, Article 11 Technical Documentation, is both the widest raw gap (Darwinbox 60, Ribbon 42) and the heaviest weighted swing, and at 20% weight it makes up 75% of the weighted advantage Darwinbox holds across the 2 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +2.2 — the difference between the two totals before either is rounded. Shares are of 7.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +2.2.

§ 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.
