§ The result
CodeSignal leads Moonhub on 6 of the 7 criteria.
CodeSignal sits 13 points above Moonhub under rubric v1.0 — 43 against 30 — with CodeSignal filed under Assessment and Moonhub under Sourcing. CodeSignal leads 6 of the 7 criteria and the remaining criterion is level, so Moonhub is ahead on none of them; the closest of the 6 CodeSignal leads is Human Oversight Design, CodeSignal 55 to Moonhub 48. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (CodeSignal 45, Moonhub 18, 18% weight), but it accounts for only 38% of the weighted advantage CodeSignal holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +12.6 — the difference between the two totals before either is rounded. Shares are of 12.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +13 beside that +12.6.

§ 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.
