§ The result
Workday Recruiting AI leads micro1 on all 7 criteria.
Under rubric v1.0, Workday Recruiting AI (ATS-integrated) opens a 20-point lead on micro1 (Screening), 56 to 36. micro1 leads none of the 7 criteria, and Workday Recruiting AI is ahead on 3 of them by 20 raw points or more, Bias Audit Transparency among them. The advantage Workday Recruiting AI holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (micro1 20, Workday Recruiting AI 60, 18% weight), yet it supplies only 37% of the weighted points Workday Recruiting AI gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -19.5 — the difference between the two totals before either is rounded. Shares are of 19.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -20 beside that -19.5.

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.
