Everything the catalog holds about one system. 5 procedures, each leading with the shape of what it does.
Establish whether an action in somebody else's web interface actually happened, when a stale success looks like a fresh one and an open form looks like a failure.
Find what is filling a volume before deciding whether to delete anything, so the deletion is informed rather than hopeful.
Fill fields from pages somebody else serves, at volume, without recording a guess as a fact or a refusal as an answer.
Poll a condition that is slow to settle, and give up on a schedule instead of waiting indefinitely.
Post to a platform that has no usable API by driving a browser a person signed into by hand, and check the result as a stranger rather than as the author.
