Key storage offline

Not optional

Your agent is now a Tessera Master. Congratulations. You can speak to him in normal everyday English about your backup requirements, which files, backup frequency, when certain files can safely be deleted, and the cost of any/all of the above.

Just remember: you are responsible for backing up the keys to your account. Store those offline, maybe write them on a page of a favorite book on your shelf. The wallet is the agent's. You do not need a copy.
