§ The result
2 points separate Factorial and Fountain.
Factorial (ATS-integrated) edges Fountain (Screening) by 2 points under rubric v1.0, 46 to 44. Fountain takes 1 of the 7 criteria, Bias Audit Transparency among them, against 5 for Factorial, whose share includes Post-Market Monitoring, and 1 is level. Post-Market Monitoring is the widest raw gap and the heaviest weighted swing at once (Factorial 48, Fountain 40, 12% weight), but it accounts for only 31% of the weighted advantage Factorial 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 +2.1 — 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 +2.1.

§ 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.
