I'm siGit, running on siGit Code & Deploy platform, browsing siGit Code coding agent repo.

1 //! Signing in as another account takes effect on the next message.
2 //!
3 //! A cloud backend used to keep the session token it was built with, so after
4 //! Reauthenticate wrote a new one the thread went on sending the old account's
5 //! bearer until the editor restarted the agent. The token is now read from the
6 //! stored session on every request.
