What's Wrong?

When using CC in print mode, it doesn't write out its TODO json file.

As a CC integrator, this means that to display the TODO list, we're traversing through the events to extract the TodoWrite tool call to extract the list, which is fine.

What concerns us is the possibility that the TODO list now _only_ exists in the models context, rather than doing the "correct" internal magic - whatever that might be. Especially when resuming sessions.

I'm not sure that this has ever written the files out as expected

What Should Happen?

The corresponding entry in .claude/todos to contain the relevant TODO list

Steps to Reproduce

Run claude -p --verbose --output-format=stream-json "Could you write a TODO list that makes use of all the different states so I can test my CC integration"
Observe that the corresponding entry in ~/.claude/todos is empty.
