# Citation-issue taxonomy

Every URL the AI subject cited in its answer is labelled with one of the three types below. Multiple URLs can have different labels within the same finding.

## Contradictory

The cited source contradicts the AI's claim — the verbatim regulator text in the source says something different.

## Hallucinated

The cited source does not exist or does not contain the cited content.

## Missing

The AI made the claim without citing a source where one is required.
