The public dataset reports citation rates, rankings, and evidence counts. It excludes internal query identifiers, raw cited URLs, and answer-engine provider payloads. MRI measures observed root-domain citations in monitored prompts, not all AI answers, recommendation quality, web traffic or commercial performance. A citation is not source support.
AuthorityTech publication intelligence projection is a downstream practitioner projection. It is not source evidence, citation provenance, or sameAs identity for the neutral dataset.
