§ The result
4 points separate Workstream and Aon Assessment.
Workstream holds a 4-point edge over Aon Assessment under rubric v1.0, 39 to 35, across the Screening and Assessment cohorts. The 7 criteria split 5 to 1 in favour of Workstream, with 1 level: Workstream is ahead on Human Oversight Design and Aon Assessment on Bias Audit Transparency. The advantage Workstream holds is spread out: Human Oversight Design is both the widest raw gap and the heaviest weighted swing (Aon Assessment 45, Workstream 61, 12% weight), yet it supplies only 35% of the weighted points Workstream gains across the 5 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -3.6 — the difference between the two totals before either is rounded. Shares are of 7.2 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.
