§ The result
Classet takes the total, Bullhorn takes more of the criteria.
Classet (Screening) edges Bullhorn (ATS-integrated) by 1 point under rubric v1.0, 55 to 54. Bullhorn leads more of the criteria than Classet — 4 to 3 — but Bias Audit Transparency, which Classet leads, carries 18% of the rubric, and the weighted sum still falls to Classet. Bias Audit Transparency, at 18%, is the heaviest weighted swing and goes to Classet (Bullhorn 58, Classet 76), 53% of the weighted advantage it holds, while the widest raw gap is Post-Market Monitoring, Bullhorn 35 to Classet 58.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -1.2 — the difference between the two totals before either is rounded. Shares are of 11.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -1 beside that -1.2.

§ 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.
