§ The result
Greenhouse leads Jack & Jill on all 7 criteria.
Under rubric v1.0, Greenhouse (ATS-integrated) opens an 18-point lead on Jack & Jill (Sourcing), 67 (D) to 49 (F). Greenhouse leads every one of the 7 criteria, Jack & Jill none of them, and the closest of the 7 is Human Oversight Design, Greenhouse 66 to Jack & Jill 58. The advantage Greenhouse holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Greenhouse 78, Jack & Jill 44, 20% weight), yet it supplies only 37% of the weighted points Greenhouse gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +18.4 — the difference between the two totals before either is rounded. Shares are of 18.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +18 beside that +18.4.

§ 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.
