§ The result
Fuel50 leads Fountain on 6 of the 7 criteria.
Fuel50 sits 14 points above Fountain under rubric v1.0 — 58 against 44 — with Fuel50 filed under Sourcing and Fountain under Screening. Fuel50 leads 6 of the 7 criteria and the remaining criterion is level, so Fountain is ahead on none of them; the closest of the 6 Fuel50 leads is FRIA Support, Fountain 30 to Fuel50 32. One criterion, Bias Audit Transparency, is both the widest raw gap (Fountain 30, Fuel50 68) and the heaviest weighted swing, and at 18% weight it makes up 50% of the weighted advantage Fuel50 holds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -13.7 — the difference between the two totals before either is rounded. Shares are of 13.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -14 beside that -13.7.

§ 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.
