A logoff or\nsession replacement can consequently move an unrelated connection to\nNEED_RECONNECT or NEED_SETUP.\n\nPass the target session itself and select connections using either the\nconnection-local session xarray or the session's permanent channel list.\nUse the same association test while waiting for requests to drain.\n\nSerialize session-wide status changes under request_lock and do not\noverwrite EXITING or RELEASING. Protect the shutdown transition with the\nsame lock so a concurrent session update cannot revive a
