§ The result
Paradox takes the total, Pin takes more of the criteria.
Paradox holds a 1-point edge over Pin under rubric v1.0, 41 to 40, across the Scheduling and Sourcing cohorts. Pin leads more of the criteria, 4 against 2 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, Pin 35 — and at an 18% weight it carries 57% 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 +1.2 — 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 +1 beside that +1.2.

Raw score per criterion, with weighted delta.

§ 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.
