I'm checking why TestDAGRecovery failed

I'm checking why TestDAGRecovery failed

sometimes recovery tests are flaky, I simply restarted the last precommit job

okumin · 2024-12-23T14:14:37Z

@abstractdog Sorry, my hand-made refactoring included a mistake. I copy-pasted the method names used in the original condition. I appreciate it if you could double-check it.

missed it, I saw it's fixed, glad to see that unit tests revealed the problem
+1 still holds if tests will pass
