§ The result
4 points separate UKG and Pillar.
UKG (ATS-integrated) edges Pillar (Screening) by 4 points under rubric v1.0, 44 to 40. UKG leads 6 of the 7 criteria, including Data Governance Disclosure, while Pillar leads 1, including Bias Audit Transparency. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (Pillar 45, UKG 56, 15% weight), but it accounts for only 32% of the weighted advantage UKG 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 -3.6 — the difference between the two totals before either is rounded. Shares are of 6.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -4 beside that -3.6.

§ 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.
