Bug: @Computer routes native Windows requests to a browser-only CUA runtime.

When I invoked @Computer in Codex Desktop for Windows and asked it to access any native Windows application, the active connector reported:

• Native apps: none
• Desktop windows: none
• Browser tabs: none
• Native app controls: unavailable

This was incorrect: the Windows desktop was present and the native Computer Use helper was running. Initializing @oai/sky in the active browser-only session also failed with: Trusted RPC service is not configured: sky.

The problem is not specific to LM Studio or any other target application. It is a connector-routing/configuration problem.

What steps can reproduce the bug?

Feedback ID: 01a09a73-4933-7411-ae67-3e843311dacb

What is the expected behavior?

When a user invokes @Computer for a Windows desktop task, Codex should automatically select the native Computer Use runtime and expose the Windows app/window APIs. The request should not be routed to a browser-only cua_repl session, and restarting Codex should not regenerate a browser-only surface when the native computer-use plugin is enabled.

Additional information

The native runtime used CUA_REPL_ENABLED_SURFACES=browser,computer and trusted the sky service (@oai/sky/service). It successfully returned the installed-app inventory and controlled Calculator; the display changed from 0 to 7 after a native click. No credentials, personal files, or sensitive data were entered or uploaded. This is a Codex app/plugin routing issue, not an LM Studio issue.

Start by reproducing the Windows case using feedback ID 01a09a73-4933-7411-ae67-3e843311dacb, then trace @Computer routing between the browser-only cua_repl session and the native Computer Use runtime. Check the CUA_REPL_ENABLED_SURFACES setting and @oai/sky/service configuration; done means native Windows apps and windows are exposed instead of browser-only surfaces.
