The framework should've been moved to 'completed_frameworks' after the failover timeout. Of course, if a master fails over this information is lost so you can't reliably depend on it. When master starts storing persistent state about frameworks (likely couple of releases away), a re-registration attempt in such a case would be denied by the master. So that could be your signal. Alternatively, with persistence, you could also more reliably depend on "/state.json" to get this info. To take a step back, what is the problem you are trying to solve? Thanks,
