§ The result
UKG leads Zappyhire on all 7 criteria.
UKG sits 10 points above Zappyhire under rubric v1.0 — 44 against 34 — with UKG filed under ATS-integrated and Zappyhire under Screening. UKG is ahead of Zappyhire on all 7 criteria but on none of them by as much as 20 raw points, the closest being Bias Audit Transparency at UKG 30 to Zappyhire 28. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (UKG 48, Zappyhire 30, 20% weight), but it accounts for only 37% of the weighted advantage UKG holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +9.8 — the difference between the two totals before either is rounded. Shares are of 9.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +10 beside that +9.8.

§ 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.
