Nielsen static configuration loaders carry the App ID in the path.

The static Browser SDK loader uses /conf/{apid}.js. Its name and ns fragment settings are documented for the browser. Legacy configuration queries and measurement pings are separate request surfaces.

Field	Required	What it checks	Rule ids	Source
`apid`	required	Nielsen documents the SDK configuration URL as /conf/{apid}.js, using the App ID supplied during onboarding. Fix: Copy the Nielsen App ID into the path before .js.	`vendor.nielsen-config.param.apid.missing` `vendor.nielsen-config.param.apid.empty`	docs
