§ The result
Greenhouse leads X0PA AI on all 7 criteria.
Greenhouse finishes 19 points clear of X0PA AI under rubric v1.0 — 67 (D) against 48 (F) — across the ATS-integrated and Assessment cohorts. Greenhouse leads every one of the 7 criteria, X0PA AI none of them, and the closest of the 7 is FRIA Support, Greenhouse 42 to X0PA AI 38. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Greenhouse 86, X0PA AI 44 — and at an 18% weight it carries 41% of the weighted advantage Greenhouse holds across the 7 criteria on that side of the table.

0.3 weighted points to Greenhouse
Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +18.5 — the difference between the two totals before either is rounded. Shares are of 18.5 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 +18.5.

§ 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.
