§ The result
HiBob leads Mercor on all 7 criteria.
Under rubric v1.0, HiBob (ATS-integrated) opens a 23-point lead on Mercor (Screening), 46 to 23. Mercor leads none of the 7 criteria, and HiBob is ahead on 5 of them by 20 raw points or more, Article 11 Technical Documentation among them. The widest raw gap and the heaviest weighted swing fall on different criteria: Data Governance Disclosure (HiBob 57, Mercor 22) and Article 11 Technical Documentation at 20% (HiBob 55, Mercor 22), the second being 28% of the weighted advantage HiBob 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 +23.3 — the difference between the two totals before either is rounded. Shares are of 23.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +23 beside that +23.3.

§ 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.
