Send the structure, not the archive.
- The exact operational question the output should answer
- Existing column headers, if useful; no fabricated sample required
- How often the export is produced and who reviews the result
- Existing source and target exports only after disclosure permission and a private route are agreed
Describe the work first. Operalith can create fictional examples from the structure when needed; you do not need to clean a sample or prepare an identifier crosswalk.
