§ The result
Paradox takes the total, Personio takes more of the criteria.
Paradox (Scheduling) edges Personio (ATS-integrated) by 1 point under rubric v1.0, 41 to 40. Personio 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. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Paradox 50, Personio 25 — and at an 18% weight it carries 95% of the weighted advantage Paradox holds across the 2 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +1.0 — the difference between the two totals before either is rounded. Shares are of 8.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +1 beside that +1.0.

§ 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.
