In the ARC framework, grounded search responses are parsed to extract live web citations across providers such as Google Gemini, OpenAI ChatGPT, and Anthropic Claude. The system analyzes the entire grounding cascade, distinguishing between selected and unselected sources to reveal which retrieved pages were explicitly cited in the final answer versus merely browsed during retrieval. Beyond tracking plain visibility and citation share, this process powers source fact fidelity checks through veracity engines and enables Grounded Memory validation, verifying whether live retrieval accurately reflects brand facts or introduces hallucinations and omissions.
