§ The result
Codility leads Personio on all 7 criteria.
Codility sits 14 points above Personio under rubric v1.0 — 54 against 40 — with Codility filed under Assessment and Personio under ATS-integrated. Codility leads every one of the 7 criteria, Personio none of them, and the closest of the 7 is Post-Market Monitoring, Codility 50 to Personio 48. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Codility 60, Personio 40, 20% weight), but it accounts for only 30% of the weighted advantage Codility holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +13.3 — the difference between the two totals before either is rounded. Shares are of 13.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +14 beside that +13.3.

§ 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.
