§ The result
Retorio takes the total, Willo takes more of the criteria.
Retorio (Assessment) edges Willo (Video interview) by 3 points under rubric v1.0, 44 to 41. Willo leads more of the criteria than Retorio — 4 to 3 — but Article 11 Technical Documentation, which Retorio leads, carries 20% of the rubric, and the weighted sum still falls to Retorio. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Retorio 50, Willo 38 — and at a 20% weight it carries 48% of the weighted advantage Retorio holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +2.9 — the difference between the two totals before either is rounded. Shares are of 7.0 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 +2.9.

§ 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.
