Phenom, filed under Sourcing, comes out 13 points above Workstream, filed under Screening: 52 against 39 under rubric v1.0. Workstream leads more of the criteria, 4 against 3 for Phenom, yet Phenom takes Bias Audit Transparency, which carries 18% of the rubric, and the weighted sum with it. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Phenom 75, Workstream 20 — and at an 18% weight it carries 67% of the weighted advantage Phenom 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 +13.8 — the difference between the two totals before either is rounded. Shares are of 15.9 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 +13.8.

§ 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.
