§ The result
Plum leads Paradox on all 7 criteria.
Plum sits 13 points above Paradox under rubric v1.0 — 54 against 41 — with Plum filed under Assessment and Paradox under Scheduling. Plum leads every one of the 7 criteria, Paradox none of them, and the closest of the 7 is Post-Market Monitoring, Paradox 35 to Plum 36. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Paradox 50, Plum 83 — and at an 18% weight it carries 45% of the weighted advantage Plum holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -13.1 — the difference between the two totals before either is rounded. Shares are of 13.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -13 beside that -13.1.

§ 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.
