## Summary
- Keep raw diagnostic staging in private cache and give each exported
archive a unique request directory.
- Remove that request directory after the CLI pull, including failed
transfers.
- Replace files from the previous extracted snapshot while preserving
unrelated destination files.
- Document that the old rooted-device fallback is not scrubbed.
Follow-up to #2061. The refreshed export tests now cover independent
archive outputs and stale snapshot replacement.
