Ship four pieces: a one-page cover sheet, a chronology of the case, the raw extract, and a limitation note. The extract can stay CSV or JSON; the story should not live only in someone’s inbox.
Checksum the extract

Keep screenshots secondary
Screenshots help when a UI state matters, but they are poor as the only evidence. Prefer structured fields your audit trail reporting app can regenerate.
