§ The result
CodeSignal leads Aon Assessment by 8 points.
CodeSignal scores 43 and Aon Assessment 35 under rubric v1.0 — an 8-point gap inside the Assessment cohort. CodeSignal leads 5 of the 7 criteria, including Bias Audit Transparency, while Aon Assessment leads 1, including Article 11 Technical Documentation, and 1 is level. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Aon Assessment 30, CodeSignal 45, 18% weight), but it accounts for only 32% of the weighted advantage CodeSignal holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -8.0 — the difference between the two totals before either is rounded. Shares are of 8.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -8.0.

§ 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.
