§ The result
Brainner leads Willo by 5 points.
Under rubric v1.0, Brainner, filed under Screening, finishes on 46 and Willo, filed under Video interview, on 41, 5 points apart. The 7 criteria split 5 to 1 in favour of Brainner, with 1 level: Brainner is ahead on Article 11 Technical Documentation and Willo on Human Oversight Design. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Brainner 52, Willo 38, 20% weight), but it accounts for only 39% of the weighted advantage Brainner holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +5.7 — the difference between the two totals before either is rounded. Shares are of 8.6 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 +5.7.

§ 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.
