Feature request: create/register a new local Codex project and first thread from mobile

[Celob185]

Request

Allow ChatGPT Codex mobile to create/register a new local Codex project and start the first thread on a connected desktop host.

Current behavior

Today, mobile can continue local projects that already appear in the project list, but it does not appear to provide a first-class way to bootstrap/register a new local folder from mobile.

In a controlled local comparison:

creation path	local state shape	mobile result
codex debug app-server send-message-v2 ... from a fresh folder	source=vscode, thread_source=NULL, originator=Codex Desktop	folder appeared in ChatGPT Codex mobile
codex exec -C <folder> ... from a fresh folder	source=exec, thread_source=user, originator=Codex Desktop	local session was created, but folder did not appear in ChatGPT Codex mobile

Token usage was effectively the same in this comparison (23432 vs 23417 total tokens in local rollout evidence), so the practical difference was project registration / mobile visibility rather than cost.

Desired behavior

From ChatGPT Codex mobile, I want to:

1. Choose a connected desktop host.
2. Select or enter a local folder path on that host.
3. Create/register the folder as a Codex project.
4. Start the first thread in that project.

Why this matters

Mobile is useful for continuing Codex work remotely, but today I still need to use a desktop/app-server path once before mobile can see a new local project. This makes mobile less useful as a true remote-control surface for starting work.

Suggested implementation

Expose the same registration behavior used by Desktop/app-server-created threads as a first-class mobile action, for example:

• "New local project"
• "Register folder on host"
• "Start thread in folder"

This would avoid requiring users to run codex debug app-server send-message-v2 manually just to make a folder visible from mobile.
