§ The result
2 points separate Coderbyte and Personio.
Coderbyte holds a 2-point edge over Personio under rubric v1.0, 42 to 40, across the Assessment and ATS-integrated cohorts. The 7 criteria split 5 to 2 in favour of Coderbyte: Coderbyte is ahead on Human Oversight Design and Personio on Post-Market Monitoring. The advantage Coderbyte holds is spread out: Human Oversight Design is both the widest raw gap and the heaviest weighted swing (Coderbyte 60, Personio 48, 12% weight), yet it supplies only 37% of the weighted points Coderbyte gains across the 5 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +2.1 — the difference between the two totals before either is rounded. Shares are of 5.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +2.1.

§ 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.
