§ The result
HiBob leads Workstream on 6 of the 7 criteria.
HiBob scores 46 and Workstream 39 under rubric v1.0, a 7-point gap across the ATS-integrated and Screening cohorts. HiBob leads 6 of the 7 criteria and the remaining criterion is level, so Workstream is ahead on none of them; the closest of the 6 HiBob leads is Human Oversight Design, HiBob 63 to Workstream 61. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (HiBob 55, Workstream 40, 20% weight), but it accounts for only 39% of the weighted advantage HiBob holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +7.8 — the difference between the two totals before either is rounded. Shares are of 7.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +7 beside that +7.8.

§ 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.
