§ The result
3 points separate CodeSignal and Paycor.
CodeSignal (Assessment) edges Paycor (ATS-integrated) by 3 points under rubric v1.0, 43 to 40. CodeSignal and Paycor each lead 2 of the 7 criteria, with 3 level, though the side of the split CodeSignal holds (headed by Bias Audit Transparency) adds up to more weighted points. One criterion, Bias Audit Transparency, is both the widest raw gap (CodeSignal 45, Paycor 25) and the heaviest weighted swing, and at 18% weight it makes up 87% of the weighted advantage CodeSignal holds across the 2 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 4 figures above sum to +3.5 — the difference between the two totals before either is rounded. Shares are of 4.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +3.5.

§ 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.
