§ The result
Tenzo AI takes the total, Spark Hire takes more of the criteria.
Tenzo AI (Screening) edges Spark Hire (Video interview) by 3 points under rubric v1.0, 56 to 53. Spark Hire leads more of the criteria than Tenzo AI — 4 to 3 — but Bias Audit Transparency, which Tenzo AI leads, carries 18% of the rubric, and the weighted sum still falls to Tenzo AI. One criterion, Bias Audit Transparency, is both the widest raw gap (Spark Hire 62, Tenzo AI 83) and the heaviest weighted swing, and at 18% weight it makes up 62% of the weighted advantage Tenzo AI holds across the 3 criteria it leads.

Shares are of 9.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -3 beside that -2.4.

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.
