§ The result
HackerRank leads Paradox on all 7 criteria.
HackerRank sits 14 points above Paradox under rubric v1.0 — 55 against 41 — with HackerRank filed under Assessment and Paradox under Scheduling. HackerRank leads every one of the 7 criteria, Paradox none of them, and the closest of the 7 is FRIA Support, HackerRank 35 to Paradox 25. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (HackerRank 60, Paradox 40, 20% weight), but it accounts for only 29% 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 +14.0 — the difference between the two totals before either is rounded. Shares are of 14.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +14 beside that +14.0.

§ 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.
