§ The result
Plum leads SeekOut on all 7 criteria.
Plum finishes 20 points clear of SeekOut under rubric v1.0 — 54 against 34 — across the Assessment and Sourcing cohorts. Plum leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; SeekOut leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Plum 83, SeekOut 40, 18% weight), but it accounts for only 39% 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 +20.0 — the difference between the two totals before either is rounded. Shares are of 20.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +20 beside that +20.0.

§ 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.
