A deterministic verification script found that 4 of 10 quotes attributed to Naval Ravikant's book could not be located in the actual source text — yet a synthesis LLM had confidently presented them as verified. The script doesn't trust the LLM's own grep check; it re-verifies independently. This is a presentation-layer failure that retrieval would never catch.
