§ The result
Workstream leads Cognisess on 6 of the 7 criteria.
Workstream scores 39 and Cognisess 30 under rubric v1.0, a 9-point gap across the Screening and Assessment cohorts. Workstream leads 6 of the 7 criteria and the remaining criterion is level, so Cognisess is ahead on none of them; the closest of the 6 Workstream leads is Post-Market Monitoring, Cognisess 32 to Workstream 35. Human Oversight Design is the widest raw gap (Cognisess 42, Workstream 61) but not the heaviest weighted swing, which is Article 11 Technical Documentation at 20% (Cognisess 25, Workstream 40), 34% of the weighted advantage Workstream builds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -8.7 — the difference between the two totals before either is rounded. Shares are of 8.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -9 beside that -8.7.

§ 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.
