§ The result
Lever leads Willo by 8 points.
Lever scores 49 and Willo 41 under rubric v1.0, an 8-point gap across the ATS-integrated and Video interview cohorts. Lever leads 6 of the 7 criteria, including Article 11 Technical Documentation, while Willo leads 1, including Human Oversight Design. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Lever 52, Willo 38, 20% weight), but it accounts for only 34% of the weighted advantage Lever holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +7.9 — the difference between the two totals before either is rounded. Shares are of 8.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +8 beside that +7.9.

§ 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.
