§ The result
3 points separate Coderbyte and Workstream.
Coderbyte holds a 3-point edge over Workstream under rubric v1.0, 42 to 39, across the Assessment and Screening cohorts. The 7 criteria split 5 to 1 in favour of Coderbyte, with 1 level: Coderbyte is ahead on Data Governance Disclosure and Workstream on Human Oversight Design. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (Coderbyte 56, Workstream 47, 15% weight), but it accounts for only 35% 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 +3.7 — 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 +3 beside that +3.7.

§ 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.
