§ The result
Emmersion leads Aon Assessment by 9 points.
Emmersion scores 44 and Aon Assessment 35 under rubric v1.0 — a 9-point gap inside the Assessment cohort. Aon Assessment takes 1 of the 7 criteria, Bias Audit Transparency among them, against 6 for Emmersion, whose share includes Article 11 Technical Documentation. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Aon Assessment 40, Emmersion 57, 20% weight), but it accounts for only 36% of the weighted advantage Emmersion holds across the 6 criteria on that side of the table.

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.
