§ The result
Wellfound takes the total, Fountain takes more of the criteria.
Wellfound scores 52 and Fountain 44 under rubric v1.0 — an 8-point gap inside the Screening cohort. Fountain leads more of the criteria than Wellfound — 4 to 3 — but Bias Audit Transparency, which Wellfound leads, carries 18% of the rubric, and the weighted sum still falls to Wellfound. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Fountain 30, Wellfound 82 — and at an 18% weight it carries 76% of the weighted advantage Wellfound holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -7.7 — the difference between the two totals before either is rounded. Shares are of 16.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -7.7.

§ 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.
