The Python holder's HELD read is bounded, so a lock leaked on refusal fails the subtest naming the leak instead of hanging CI. A test-only hook runs a closure between try_with_exclusive_lock's pre-lock look and its try-lock, so a test puts the link there and checks the refusal, the untouched target and the freed lock.
