When a knowledge management system verified 9 quotes extracted from a single book, only 4 of 9 (44%) matched the source verbatim. The remaining 5 were paraphrased, fabricated, or mis-cited by the synthesis LLM — even though the LLM itself had claimed to verify them. This is a concrete, measured instance of the 'synthesis quote verification drift' failure mode that affects any AI summarization pipeline.
