§ The result
iMocha leads Workstream on all 7 criteria.
Under rubric v1.0, iMocha (Assessment) opens a 17-point lead on Workstream (Screening), 56 to 39. Of the 7 criteria Workstream wins none, and the narrowest lead iMocha holds is on Human Oversight Design, iMocha 64 to Workstream 61. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (iMocha 68, Workstream 40, 20% weight), but it accounts for only 33% of the weighted advantage iMocha 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 +17.1 — the difference between the two totals before either is rounded. Shares are of 17.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +17 beside that +17.1.

§ 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.
