Windows Codex 26.527 package includes the Browser/Chrome/Computer Use bundled plugin files locally, but the runtime availability resolver returns statsig-disabled and writes an active openai-bundled marketplace containing only latex.

This looks like a rollout/trust-gate issue rather than a missing local package file.

Related: #21440, but this report is for a newer 26.527 package where the installed Store package does contain browser, chrome, and computer-use.

Summary

This looks like a rollout/trust-gate issue rather than a missing local package file.

Related: #21440, but this report is for a newer 26.527 package where the installed Store package does contain browser, chrome, and computer-use.

Environment

OS: Windows
Codex Windows Store package: OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0
Codex desktop release from logs: 26.527.31326
Codex changelog reference: https://developers.openai.com/codex/changelog?type=codex-app
In-app feedback ID: 019e36d0-d51c-7011-918d-48dec2cda97c

The Codex changelog entry for Codex app 26.527 says Computer Use now works on Windows.

Expected behavior

On this Windows install, Browser Use / Computer Use should be available, and the active openai-bundled marketplace should expose:

browser
chrome
computer-use
latex

The active tools should include the Browser/Computer Use path, including node_repl-backed browser tooling where appropriate.

Actual behavior

Desktop logs repeatedly show Browser Use being disabled by Statsig:

browser_use_availability_resolved available=false browserPane=true platform=Windows reason=statsig-disabled release=26.527.31326

After that, the app writes the active bundled marketplace at:

%USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled

with only:

latex

Local package evidence

The installed Windows Store package contains the full bundled plugin set:

C:\Program Files\WindowsApps\OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0\app\resources\plugins\openai-bundled\plugins

browser
chrome
computer-use
latex

The package marketplace file under:

C:\Program Files\WindowsApps\OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0\app\resources\plugins\openai-bundled\.agents\plugins\marketplace.json

also lists all four plugins.

However, the desktop/runtime-written marketplace under %USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled exposes only latex.

Recent log evidence

Working machine comparison

A separate Windows machine with the same Store package:

OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0

reports:

browser_use_availability_resolved available=true browserPane=true platform=Windows reason=available release=26.527.31326

and has the bundled marketplace/plugin cache entries:

browser
chrome
computer-use
latex

~/.codex/plugins/cache/openai-bundled/browser/26.527.31326
~/.codex/plugins/cache/openai-bundled/chrome/26.527.31326
~/.codex/plugins/cache/openai-bundled/computer-use/26.527.31326

Active tools on that machine include:

mcp__node_repl__.js
mcp__node_repl__.js_add_node_module_dir
mcp__node_repl__.js_reset

Manual `node_repl` workaround findings

node_repl.exe exists:

%LOCALAPPDATA%\OpenAI\Codex\bin\34ab3e1324cc55b5\node_repl.exe

System Node is too old for this node_repl:

C:\Program Files\nodejs\node.exe
v22.18.0
node_repl requires >= v22.22.0

Bundled Codex Node works:

%LOCALAPPDATA%\OpenAI\Codex\bin\5b9024f90663758b\node.exe
v24.14.0

A manual MCP entry can make generic JS execution work:

[mcp_servers.node_repl]
args = ["--disable-sandbox"]
command = '%LOCALAPPDATA%\OpenAI\Codex\bin\34ab3e1324cc55b5\node_repl.exe'

[mcp_servers.node_repl.env]
BROWSER_USE_AVAILABLE_BACKENDS = "chrome,iab"
CODEX_CLI_PATH = '%LOCALAPPDATA%\OpenAI\Codex\bin\7dea4a003bc76627\codex.exe'
NODE_REPL_NODE_PATH = '%LOCALAPPDATA%\OpenAI\Codex\bin\5b9024f90663758b\node.exe'

codex mcp list then shows node_repl enabled with those env vars.

However, this only restores generic JS execution. It does not restore Browser Use / Computer Use.

When manually importing the bundled Browser client:

%USERPROFILE%\.codex\plugins\cache\openai-bundled\browser\26.527.31326\scripts\browser-client.mjs

the call fails with:

privileged native pipe bridge is not available; browser-client is not trusted

This also happened with a local-browser copy. That suggests local plugin installation and manual node_repl registration cannot recreate the trusted/native desktop bridge while the runtime gate remains disabled.

Safety note

Do not point the openai-bundled marketplace directly at:

C:\Program Files\WindowsApps\OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0\app\resources\plugins\openai-bundled

while the desktop app is open. That caused desktop launch dialogs similar to:

Error launching app
Unable to find Electron app at C:\Program Files\WindowsApps\OpenAI.Codex_26.527.3686.0_x6...\type=click&tag=...
Cannot find module 'C:\Program Files\WindowsApps\OpenAI.Codex_26.527.3686.0_x...\type=click&tag=...'

The config was restored so openai-bundled points back to:

%USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled

Request

Please check why this machine/account is receiving reason=statsig-disabled for Browser/Computer Use on Windows even though:

Codex app package: OpenAI.Codex_26.527.3686.0_x64__2p2nqsd0c76g0
Desktop release: 26.527.31326
Installed package includes browser/chrome/computer-use
Another machine with the same package receives reason=available

It would also help if Codex exposed a diagnostic command that shows the resolved Browser/Computer Use rollout decision, account/device identifiers relevant to the gate, and whether the trusted native Browser/Computer bridge is available.
