§ The result
Paradox takes the total, Workstream takes more of the criteria.
Paradox holds a 2-point edge over Workstream under rubric v1.0, 41 to 39, across the Scheduling and Screening cohorts. Workstream leads more of the criteria, 4 against 1 for Paradox, yet Paradox takes Bias Audit Transparency, which carries 18% of the rubric, and the weighted sum with it. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Paradox 50, Workstream 20 — and at an 18% weight it carries 100% of the weighted advantage Paradox holds across the 1 criterion on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +2.6 — the difference between the two totals before either is rounded. Shares are of 8.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +2.6.

§ 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.
