§ The result
Codility leads Paycor on all 7 criteria.
Codility sits 14 points above Paycor under rubric v1.0 — 54 against 40 — with Codility filed under Assessment and Paycor under ATS-integrated. Codility takes all 7 criteria and Paycor none of them; the nearest contest is Data Governance Disclosure, Codility 57 to Paycor 50. The advantage Codility holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Codility 60, Paycor 40, 20% weight), yet it supplies only 28% of the weighted points Codility gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +14.1 — the difference between the two totals before either is rounded. Shares are of 14.1 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 +14.1.

§ 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.
