[Regression][macOS 26.803] Local/Worktree selector still missing from new-task composer

Codex / ChatGPT desktop version

• Version: 26.803.61601
• Build: 6396
• Platform: macOS 26.6 (25G5028f), arm64
• Surface: Codex in the unified ChatGPT desktop app

What happened?

When creating a new Codex task with the local project plural selected, the composer does not show any execution-environment control.

The composer footer shows only:

• add / attachment button
• Full access permission control
• model selector (5.6 Sol Extra High)
• microphone
• send button

There is no visible Local, Work locally, Worktree, or New worktree selector. This prevents choosing an isolated managed worktree before submitting the task and leaves no visible confirmation of where the task will run.

Steps to reproduce

1. Open the unified ChatGPT desktop app on macOS.
2. Switch to Codex.
3. Select a local Git-backed project.
4. Start a new task.
5. Inspect the composer controls before submitting.

Expected behavior

The composer should expose the Local/Worktree environment selector described in the current documentation, including a starting-branch selector when Worktree is chosen:

Actual behavior

No environment selector is present. Submitting from this state risks running directly in the project's shared local checkout without an explicit target choice.

Related issue

This appears to be a current reproduction of #32927, originally reported against 26.707. That issue remains open, and the same missing-selector UI is still present in 26.803.61601.

A screenshot captured on this build shows the project picker and the exact composer controls listed above.
