§ The result
Oleeo takes the total, Workstream takes more of the criteria.
Oleeo (ATS-integrated) edges Workstream (Screening) by 1 point under rubric v1.0, 40 to 39. Workstream leads more of the criteria than Oleeo — 5 to 1 — but Bias Audit Transparency, which Oleeo leads, carries 18% of the rubric, and the weighted sum still falls to Oleeo. One criterion, Bias Audit Transparency, is both the widest raw gap (Oleeo 40, Workstream 20) and the heaviest weighted swing, and at 18% weight it makes up 100% of the weighted advantage Oleeo holds across the 1 criterion it leads.

0.1 weighted points to Workstream
Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +1.6 — the difference between the two totals before either is rounded. Shares are of 5.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +1 beside that +1.6.

§ 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.
