Machine Relations Index

Answer-engine citation monitoring across Perplexity, ChatGPT Browse, Gemini grounding, Claude Web, Google AI Mode, and Google AI Overviews. MRI uses the same Publication Intelligence citation ledger but includes every cited root domain, classifies each source from deterministic taxonomy, cached domain-identity evidence, source-network membership, and observed citation behavior, and keeps unmatched long-tail domains in Other observed source instead of overclaiming source function. Brand-prompted queries are tracked but excluded from scoring to prevent self-citation gaming. Raw cited URLs, evidence paths, query ids, provider payloads, and opportunity metadata are excluded from the public artifact.
