Measurement source custody

5 public measurement sources

Operator-attribution sources stay in the matrix and exported packet; they are not substituted for measurement sources.

No ecosystem score.These five screens do not define one digital-platform market. Each keeps its own product boundary, page-view or referral denominator, participant categories, month, and permitted use. HHI values are never added, averaged, ranked into an ecosystem score, or treated as evidence of conduct.
