§ The result
Oleeo leads Mercor on all 7 criteria.
Oleeo finishes 17 points clear of Mercor under rubric v1.0 — 40 against 23 — across the ATS-integrated and Screening cohorts. Oleeo leads every one of the 7 criteria, Mercor none of them, and the closest of the 7 is FRIA Support, Mercor 20 to Oleeo 25. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Mercor 10, Oleeo 40, 18% weight), but it accounts for only 31% of the weighted advantage Oleeo 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 -17.2 — the difference between the two totals before either is rounded. Shares are of 17.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -17 beside that -17.2.

§ 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.
