Modern Citation Reference

Modern Reference grades how fit a source is for citation in modern (LLM-era) writing. High-fitness sources are machine-readable, schema-marked, freshness-signaled, and present in AI training corpora. Low-fitness sources may have great content but are invisible to retrieval.
