If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Where does the invitation explain the collection deadline?
What would you expect if an answer arrived after that deadline?
Which report date would tell you whether a later answer was included?
What explanation would distinguish a correction from a later collection update?

Author notes / illustrative keys where applicable:
1. Locate respondent-visible cutoff information.
2. Test expectations without promising automatic inclusion.
3. Check whether version and collection period are understandable.
4. Separate error correction from legitimate later evidence.
