§ The result
Paradox takes the total, Keka takes more of the criteria.
Paradox (Scheduling) edges Keka (ATS-integrated) by 4 points under rubric v1.0, 41 to 37. Keka leads more of the criteria than Paradox — 4 to 2 — but Bias Audit Transparency, which Paradox leads, carries 18% of the rubric, and the weighted sum still falls to Paradox. One criterion, Bias Audit Transparency, is both the widest raw gap (Keka 20, Paradox 50) and the heaviest weighted swing, and at 18% weight it makes up 73% of the weighted advantage Paradox holds across the 2 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -4.5 — the difference between the two totals before either is rounded. Shares are of 10.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -4 beside that -4.5.

§ 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.
