Check that state under state_lock before\nrunning response verification and security initialization, then use a local\nsecured flag to decide whether to queue the secured-connection work after\nthe state transition. This keeps duplicate or late RESPONSE packets from\nre-running the setup path and removes the unlocked post-transition state\ntest.",
