[Bug] VS Code extension passes zero workspace roots and uses unrelated inherited working directory

What version of the IDE extension are you using?

26.715.61943

What subscription do you have?

Plus

Which IDE are you using?

VS Code

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64"Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

New local Codex conversations are consistently attached to an unrelated repository instead of the folder open in the current VS Code window.

This happens even though VS Code's workspace state identifies other open projects.

The problem persists after:

• Creating a new Codex conversation
• Running Developer: Reload Window
• Closing and reopening VS Code
• Closing and reopening the Codex side panel

The Codex extension log shows that no runtime workspace roots are being sent when a turn starts:

requestRuntimeWorkspaceRootCount=0

The resulting Codex session then receives an unrelated project as its working directory and writable root. Later log entries confirm Git operations are also attempted using the incorrect directory:

Meanwhile, VS Code's own workspace state correctly contains the folder actually open in the window.

This suggests that the extension is failing to pass the active VS Code workspace to the Codex app server. When the runtime workspace-root list is empty, Codex appears to fall back to an inherited process working directory from a previously opened repository.

What steps can reproduce the bug?

Difficult to say what steps got Codex into this state, however:

• I regularly switch between projects in the same VS Code window, or open new VS Code windows with different projects, each with their own Codex panel (previously this worked fine and it always understood which project it was in)
• I have the ChatGPT app installed and make use of Codex Remote

What is the expected behavior?

Each new local Codex conversation should use the folder associated with the current VS Code window.

The active folder should be passed to the app server as a runtime workspace root.
