We do not rank them: the map shows what an operator describes, what can be observed, and what remains unknown.", "For readers, the map is a decision aid: first identify whether the question concerns access, search, attribution, or referral, then choose the measurement. This prevents transferring one operator’s rules to another.", "Check attribution quality separately: a link may lead to a homepage, a secondary summary, or the exact passage. These are three different outcomes. Record the URL beside the supported claim so any domain appearance is not counted as a citation.", "Platform comparison requires the same unit of analysis. We use a surface and a concrete observable artifact, not a brand as a whole. YandexBot, OAI-SearchBot, and a search interface must not be combined without an explicit definition.", "The editorial value of the map is choosing the next action. A bad HTTP status leads to a technical check; a missing index signal to an indexability check; a relevant answer without a link to a separate attribution experiment.
