§ The result
HeyMilo leads CodeSignal on all 7 criteria.
HeyMilo finishes 18 points clear of CodeSignal under rubric v1.0 — 61 (D) against 43 (F) — across the Screening and Assessment cohorts. HeyMilo leads every one of the 7 criteria, CodeSignal none of them, and the closest of the 7 is Customer Documentation, CodeSignal 62 to HeyMilo 66. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (CodeSignal 45, HeyMilo 83, 18% weight), but it accounts for only 39% of the weighted advantage HeyMilo 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 -17.6 — the difference between the two totals before either is rounded. Shares are of 17.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -18 beside that -17.6.

§ 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.
