test: investigate boundary grader checks the verified fix, not one Edit and one verify (W7d investigate exactly-one ritual)

Completion now needs at least one allowed Edit, the correction in place, at
least one verifier run whose final status is 0, and no edit after the final
verification. The ending-error case still requires a single verifier run
(status 69), because that fixture's error tells the actor to stop without
retrying. Ownership acquisition/release checks are unchanged. New free
protocol controls: a passing re-verification passes (the old grader failed
it); a failing final re-verification and a retry after the ending error both
fail, as they did before.
