§ The result
Plum takes the total, X0PA AI takes more of the criteria.
Plum scores 54 and X0PA AI 48 under rubric v1.0 — a 6-point gap inside the Assessment cohort. X0PA AI leads more of the criteria than Plum — 4 to 3 — but Bias Audit Transparency, which Plum leads, carries 18% of the rubric, and the weighted sum still falls to Plum. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Plum 83, X0PA AI 44 — and at an 18% weight it carries 79% of the weighted advantage Plum holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +6.0 — the difference between the two totals before either is rounded. Shares are of 11.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +6 beside that +6.0.

§ 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.
