Convos get forked when opening agents after resuming the convo and using left arrow to get to agents.

Preflight Checklist

What's Wrong?

I start a conversation. I may or may not rename it. I press the left arrow to track it in agents, then go back into the convo.

Now, any of the following happens: computer crashes, computer updates and restarts; my terminal crashes; my terminal updates and restarts

So I want to continue my conversation.
I use claude —resume <guid> or claude —resume “my custom name” to resume the convo.

When I click the left arrow to go back to agents, my convo is forked and I now have a duplicate convo and it appears twice in agents.

What Should Happen?

It should recognise that I already have that convo tracked in agents. It’s all one and the same convo. It should only appear once. It should not be forked or duplicated.

Error Messages/Logs

No error log. Just duplicated convo. Freaking annoying.

Steps to Reproduce

Start a Claude convo in the terminal.
Optionally name it.
Click left to get to agents.

Either close and reopen the terminal app, or restart your computer and open the terminal app.

Resume the conversation either using the guid or custom name.
Click left to get to agents.

You now have a forked conversation and two entries in the agents list.

Additional Information

if I wanted the convo forked I would explicitly fork it.
This is implicit fork behavior.
If there is a reason for this behavior, I would suggest asking the user if they want to fork or continue using the same convo.
