§ The result
Paradox leads micro1 by 5 points.
Under rubric v1.0, Paradox, filed under Scheduling, finishes on 41 and micro1, filed under Screening, on 36, 5 points apart. The 7 criteria split 4 to 1 in favour of Paradox, with 2 level: Paradox is ahead on Bias Audit Transparency and micro1 on Article 11 Technical Documentation. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — micro1 20, Paradox 50 — and at an 18% weight it carries 74% of the weighted advantage Paradox holds across the 4 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -5.3 — the difference between the two totals before either is rounded. Shares are of 9.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -5 beside that -5.3.

§ 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.
