§ The result
CoderPad leads Mercor on all 7 criteria.
Under rubric v1.0, CoderPad (Assessment) opens a 19-point lead on Mercor (Screening), 42 to 23. Mercor leads none of the 7 criteria, and CoderPad is ahead on 3 of them by 20 raw points or more, Data Governance Disclosure among them. The advantage CoderPad holds is spread out: Data Governance Disclosure is both the widest raw gap and the heaviest weighted swing (CoderPad 54, Mercor 22, 15% weight), yet it supplies only 26% of the weighted points CoderPad gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +18.5 — the difference between the two totals before either is rounded. Shares are of 18.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +19 beside that +18.5.

§ 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.
