When a piece of work counts as finished, and who decides: the finish contract a task is evaluated against, the coverage a change is held to, and the gates CI runs before anything is published. A worker can always say it is finished; here that sentence is a claim the repository checks, and nothing is recorded as done while any line of the contract fails.
Not in this domain: the proof behind a public claim, which is evidence; and the scope a task was allowed, which is coordination.
