Source substitution

Source substitution occurs when an AI-mediated answer relies on, cites, or appears to validate a secondary source where a canonical or governing source should have controlled the claim.

The substitution can be visible, when the wrong URL is cited, or silent, when a third-party source structures the answer while the official source is merely displayed or ignored. The correction usually requires stronger canonical surfaces, clearer internal routing and reduced ambiguity across external sources.
