Codex App: Up / down arrow historical prompts should be project specific

Version 260202.0859 (517)

What subscription do you have?

Pro

Which model were you using?

gpt-5.2

What platform is your computer?

macOS

What terminal emulator and version are you using (if applicable)?

iTerm2

What issue are you seeing?

I have 4 projects in the left panel.

I switched project 1, entered a prompt. Then I switched to project 3, entered 5-10 prompts.

I switch back to project 1, I expect up key to show me the previous prompt from _that_ session, not from project 3 - the projects are entirely different domains / languages / platforms and not applicable. I had to cycle through a lot to find the one I wanted to re-use / copy. The CLI does not have this issue.

What is the expected behavior?
