§ The result
3 points separate CodeSignal and Pin.
CodeSignal holds a 3-point edge over Pin under rubric v1.0, 43 to 40, across the Assessment and Sourcing cohorts. Pin takes 2 of the 7 criteria, Post-Market Monitoring among them, against 4 for CodeSignal, whose share includes Bias Audit Transparency, and 1 is level. The advantage CodeSignal holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (CodeSignal 45, Pin 35, 18% weight), yet it supplies only 39% of the weighted points CodeSignal gains across the 4 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +3.0 — the difference between the two totals before either is rounded. Shares are of 6.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +3.0.

§ 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.
