§ The result
HackerRank takes the total, Codility takes more of the criteria.
Within the Assessment cohort, HackerRank edges Codility by 1 point under rubric v1.0, 55 to 54. Codility leads more of the criteria than HackerRank — 5 to 1 — but Bias Audit Transparency, which HackerRank leads, carries 18% of the rubric, and the weighted sum still falls to HackerRank. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Codility 45, HackerRank 68 — and at an 18% weight it carries 100% of the weighted advantage HackerRank holds across the 1 criterion on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -1.6 — the difference between the two totals before either is rounded. Shares are of 6.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -1 beside that -1.6.

§ 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.
