§ The result
Fuel50 leads CodeSignal on 6 of the 7 criteria.
Under rubric v1.0, Fuel50 (Sourcing) opens a 15-point lead on CodeSignal (Assessment), 58 to 43. CodeSignal is ahead on none of the 7 criteria: Fuel50 takes 6, the remaining criterion is level, and the nearest of those 6 is Post-Market Monitoring, CodeSignal 38 to Fuel50 40. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — CodeSignal 38, Fuel50 70 — and at a 20% weight it carries 44% of the weighted advantage Fuel50 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 -14.7 — the difference between the two totals before either is rounded. Shares are of 14.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -15 beside that -14.7.

§ 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.
