What

In the SDK's startup-exit diagnostic logging, the code path for a permanently-closed transport (the connection used to talk to the SDK) was writing its message into the wrong variable, so that reason likely never actually showed up in the printed SDKStartup: exiting without result diagnostic line. This has been corrected.

Why

This means diagnostic logs for SDK shutdowns will now correctly report "transport closed permanently" as the reason when that's what happened, making it easier to debug why an SDK session exited.
