§ The result
Codility leads Pillar on all 7 criteria.
Codility sits 14 points above Pillar under rubric v1.0 — 54 against 40 — with Codility filed under Assessment and Pillar under Screening. Codility is ahead of Pillar on all 7 criteria but on none of them by as much as 20 raw points, the closest being Bias Audit Transparency at Codility 45 to Pillar 38. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Codility 60, Pillar 42, 20% weight), but it accounts for only 27% of the weighted advantage Codility 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 +13.5 — the difference between the two totals before either is rounded. Shares are of 13.5 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 +13.5.

§ 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.
