Operational sequence
- Preserve the original note and author.
- Track every copy, summary, code change, and redaction.
- Distinguish direct observation from patient report and institutional inference.
- Compare medication, identity, laboratory, and access records for merges.
- Attach corrections without erasing the contaminated record.
Failure states
- Overwriting original notes
- Assuming identical wording is independent corroboration
- Hiding chart access behind clinical privilege
- Deleting evidence after correction
