Title:
Chrome plugin does not work on Windows 11: node_repl js fails before browser connection

Environment:

• OS: Windows 11
• Codex Desktop
• Chrome / Google Chrome plugin
• Scenario: trying to use the Chrome plugin or browser control capability

Error:
Chrome plugin / node_repl js fails before browser connection:

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

Actual behavior:
The plugin fails before it connects to the browser. It looks like the MCP request metadata codex/sandbox-state-meta is missing the sandboxPolicy field, causing parameter validation to fail.

Expected behavior:
The Chrome plugin should start normally and connect to the browser. If sandboxPolicy is missing, there should either be a compatible default value or a clearer error message.

Notes:
This happens on Windows 11 before browser connection, so it does not look like a Chrome remote debugging port, browser version, or login-state issue. It seems more likely to be a metadata/protocol compatibility issue between Codex Desktop, MCP, and node_repl.
