Browser plugin is uninstalled and reinstalled during app startup #34069

Environment

• ChatGPT Desktop 26.715.31925 (build 5551)
• macOS 27.0 (26A5378n), arm64
• Browser plugin already installed and current

What happens

I observed the same sequence on two consecutive launches.

Browser availability starts as false and changes to true 70–125 ms later. The first bundled-plugin reconciliation has already captured a plugin list without Browser. It continues after availability is true and uninstalls the installed Browser plugin because it is not in that captured list. A queued pass then adds Browser back and installs it as missing.

Representative launch, timestamps in UTC:

19:15:48.546 reconcile started queued=false reason=startup
19:15:48.554 browser availability=false reason=browser-pane-disabled
19:15:48.621 browser availability=true reason=available

19:15:52.519 runtime marketplace written
             plugins=[chrome, computer-use, latex, visualize]
19:15:54.430 uninstall browser
             reason=not_in_bundled_marketplace_plugin_names

19:15:57.128 reconcile started queued=true reason=startup
19:15:59.361 runtime marketplace written
             plugins=[browser, chrome, computer-use, latex, visualize]
19:15:59.994 install browser reason=missing

Both passes materialized their marketplace from the current app bundle, so this is not a stale-cache issue. The first pass appears to use a stale feature-availability snapshot.

After the queued pass completes, Browser is installed again and works. During startup there is an unnecessary window where the plugin is absent.

Expected

An in-flight reconciliation should be cancelled or superseded when feature availability changes. Starting the app with a current Browser plugin and Browser enabled should perform no uninstall/install cycle.
