§ The result
2 points separate Plum and Phenom.
Plum (Assessment) edges Phenom (Sourcing) by 2 points under rubric v1.0, 54 to 52. Plum leads 5 of the 7 criteria, including Bias Audit Transparency, while Phenom leads 2, including Human Oversight Design. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Phenom 75, Plum 83, 18% weight), but it accounts for only 37% of the weighted advantage Plum holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -2.0 — the difference between the two totals before either is rounded. Shares are of 5.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -2 beside that -2.0.

§ 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.
