The result
HackerRank leads Pillar on all 7 criteria.
Under rubric v1.0, HackerRank (Assessment) opens a 15-point lead on Pillar (Screening), 55 to 40. HackerRank leads every one of the 7 criteria, Pillar none of them, and the closest of the 7 is FRIA Support, HackerRank 35 to Pillar 30. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (HackerRank 68, Pillar 38, 18% weight), but it accounts for only 36% of the weighted advantage HackerRank holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +15.1 — the difference between the two totals before either is rounded. Shares are of 15.1 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 +15.1.

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.
