§ The result
Greenhouse leads ADP on all 7 criteria.
Greenhouse finishes 19 points clear of ADP inside the ATS-integrated cohort under rubric v1.0: 67 (D) against 48 (F). Greenhouse leads every one of the 7 criteria, ADP none of them, and the closest of the 7 is Customer Documentation, ADP 58 to Greenhouse 64. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (ADP 46, Greenhouse 86, 18% weight), but it accounts for only 38% 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 -18.7 — the difference between the two totals before either is rounded. Shares are of 18.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -19 beside that -18.7.

§ 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.
