§ The result
Greenhouse leads Oleeo on all 7 criteria.
Rubric v1.0 separates Greenhouse and Oleeo, both ATS-integrated entries, by 27 points: 67 (D) for Greenhouse, 40 (F) for Oleeo. Greenhouse leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; Oleeo leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Greenhouse 86, Oleeo 40, 18% weight), but it accounts for only 31% of the weighted advantage Greenhouse 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 +26.7 — the difference between the two totals before either is rounded. Shares are of 26.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +27 beside that +26.7.

§ 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.
