§ The result
Bullhorn leads Pillar on all 7 criteria.
Bullhorn sits 14 points above Pillar under rubric v1.0 — 54 against 40 — with Bullhorn filed under ATS-integrated and Pillar under Screening. Bullhorn leads every one of the 7 criteria, Pillar none of them, and the closest of the 7 is Post-Market Monitoring, Bullhorn 35 to Pillar 33. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Bullhorn 62, Pillar 42, 20% weight), but it accounts for only 30% of the weighted advantage Bullhorn 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 +13.5 — the difference between the two totals before either is rounded. Shares are of 13.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +14 beside that +13.5.

§ 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.
