§ The result
4 points separate Pillar and micro1.
Under rubric v1.0, Pillar and micro1 finish 4 points apart, 40 to 36, as two Screening entries. The 7 criteria split 4 to 1 in favour of Pillar, with 2 level: Pillar is ahead on Bias Audit Transparency and micro1 on Article 11 Technical Documentation.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -4.2 — the difference between the two totals before either is rounded. Shares are of 7.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -4 beside that -4.2.

§ 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.
