Bug: Codex Desktop node_repl/js fails with missing sandboxPolicy, breaking Chrome and Computer Use

Description

Codex Desktop on Windows is unable to execute any node_repl/js call. The failure happens before user JavaScript runs and blocks the official Chrome and Computer Use tools, since both depend on the shared node_repl runtime.

Version

26.616.41845

Platform

• OS: Windows
• Shell: PowerShell
• App: Codex Desktop
• Date observed: June 20, 2026

Affected tools / skills

• mcp__node_repl.js
• chrome:control-chrome
• computer-use:computer-use

Error message

Mcp error: -32602: js: codex/sandbox-state-meta: missing field sandboxPolicy

### What steps can reproduce the bug?

```markdown
### Steps to reproduce

1. Open Codex Desktop `26.616.41845` on Windows.
2. Start any thread.
3. Ask Codex to use the bundled Chrome or Computer Use tool.
4. Run any `node_repl/js` call, even a minimal one like:

```js
nodeRepl.write("test");

1. Observe the error:

Mcp error: -32602: js: codex/sandbox-state-meta: missing field sandboxPolicy

### What is the expected behavior?

```markdown
### Expected behavior

`node_repl/js` should execute JavaScript successfully without a sandbox metadata error.

The bundled Chrome and Computer Use tools should initialize normally and allow Codex to control the connected Chrome session or Windows desktop as intended.

Additional information

The issue appears to be in the shared node_repl/js runtime, not in the Chrome extension or the target website. The Chrome extension showed as connected, but both Chrome control and Computer Use failed before their runtimes could initialize.

node_repl/js_reset did not resolve the issue. Shell, git, file editing, builds, and web search still worked normally.
