When LLMs synthesize pages from source materials, they routinely rewrite, paraphrase, or even fabricate direct quotes while presenting them as verbatim. A deterministic grep-based verifier caught 1 out of 6 quotes as 'not found in source' — even after the synthesis model itself claimed to have checked. The drift happens at the presentation layer, not the retrieval layer, meaning the underlying source is fine but the published text lies about it.
