§ The result
Tenzo AI takes the total, Gem takes more of the criteria.
Tenzo AI holds a 1-point edge over Gem under rubric v1.0, 56 to 55, across the Screening and Sourcing cohorts. Gem leads more of the criteria, 4 against 2 for Tenzo AI, yet Tenzo AI takes Bias Audit Transparency, which carries 18% of the rubric, and the weighted sum with it. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Gem 66, Tenzo AI 83 — and at an 18% weight it carries 80% of the weighted advantage Tenzo AI holds across the 2 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -0.5 — the difference between the two totals before either is rounded. Shares are of 7.1 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 -0.5.

§ 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.
