§ The result
Lever leads micro1 on all 7 criteria.
Lever sits 13 points above micro1 under rubric v1.0 — 49 against 36 — with Lever filed under ATS-integrated and micro1 under Screening. Lever takes all 7 criteria and micro1 none of them; the nearest contest is Article 11 Technical Documentation, Lever 52 to micro1 50. Even Bias Audit Transparency, the widest raw gap and the heaviest weighted swing (Lever 42, micro1 20, 18% weight), is only 31% of the weighted advantage Lever builds across the 7 criteria it leads.

0.4 weighted points to Lever
Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +12.7 — the difference between the two totals before either is rounded. Shares are of 12.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +13 beside that +12.7.

§ 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.
