Plum holds a 2-point edge over Glider AI under rubric v1.0, 54 to 52, with both scored in the Assessment cohort. The criteria split evenly, 3 each to Glider AI and Plum, with 1 level, and the weighted points on the side Plum holds, headed by Bias Audit Transparency, settle the total. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Glider AI 68, Plum 83 — and at an 18% weight it carries 65% 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 6 figures above sum to -2.3 — the difference between the two totals before either is rounded. Shares are of 6.0 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 -2.3.

§ 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.
