§ The result
Greenhouse leads Gem on all 7 criteria.
Greenhouse sits 12 points above Gem under rubric v1.0 — 67 (D) against 55 (F) — with Greenhouse filed under ATS-integrated and Gem under Sourcing. Greenhouse leads every one of the 7 criteria, Gem none of them, and the closest of the 7 is Customer Documentation, Gem 62 to Greenhouse 64. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Gem 58, Greenhouse 78, 20% weight), but it accounts for only 34% 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 -11.8 — the difference between the two totals before either is rounded. Shares are of 11.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -12 beside that -11.8.

§ 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.
