 ## Data Quality
 
+### Extraction Accuracy
+
+Based on sample verification against the original CSV source, the email extraction process was accurate:
+- **No hallucinations detected**: All extracted content matches the source material
+- **No data loss**: All messages and metadata were correctly extracted
+- **Accurate parsing**: Message boundaries, headers, and bodies were correctly identified and separated
+
+**Note**: While sample verification showed no hallucinations or data loss, errors may exist in the full dataset. If you encounter any extraction errors, hallucinations, or data inconsistencies, please report them by opening an issue on the [Hugging Face dataset repository](https://huggingface.co/datasets/notesbymuneeb/epstein-emails).

 ### Known Limitations
 
-- **OCR Quality**: Some original OCR errors may remain if not clearly identifiable
-- **Timestamp Formats**: Various timestamp formats preserved (not normalized)
-- **Email Addresses**: Some email addresses may be incomplete or malformed due to OCR
-- **Message Boundaries**: In rare cases, message boundaries may be ambiguous
+- **Source OCR Quality**: Some original OCR errors from the source material may remain if not clearly identifiable (these are inherited from the `tensonaut/EPSTEIN_FILES_20K` dataset, not introduced during extraction)
+- **Timestamp Formats**: Various timestamp formats preserved (not normalized) to maintain original format
+- **Email Addresses**: Some email addresses may be incomplete or malformed due to source OCR, but were extracted as-is from the source material
