§ The result
2 points separate Coderbyte and ZipRecruiter.
Coderbyte (Assessment) edges ZipRecruiter (Sourcing) by 2 points under rubric v1.0, 42 to 40. Coderbyte leads 5 of the 7 criteria, including FRIA Support, while ZipRecruiter leads 1, including Bias Audit Transparency, and 1 is level. FRIA Support is the widest raw gap and the heaviest weighted swing at once (Coderbyte 33, ZipRecruiter 27, 15% weight), but it accounts for only 28% of the weighted advantage Coderbyte holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +2.5 — the difference between the two totals before either is rounded. Shares are of 3.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +2.5.

§ 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.
