The result
HackerRank leads Pin on 6 of the 7 criteria.
HackerRank finishes 15 points clear of Pin under rubric v1.0 — 55 against 40 — across the Assessment and Sourcing cohorts.

Bias Audit Transparency is the widest raw gap (HackerRank 68, Pin 35) but not the heaviest weighted swing, which is Article 11 Technical Documentation at 20% (HackerRank 60, Pin 30), 39% of the weighted advantage HackerRank builds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +15.2 — the difference between the two totals before either is rounded. Shares are of 15.2 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 +15.2.

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.
