[Codex Desktop] Inaccessible GitHub pull requests remain in the Pull Requests list

What version of the Codex App are you using?

Unknown. The issue is observed in Codex Desktop for macOS.

What is your operating system?

macOS.

What issue are you seeing?

Codex Desktop continues to show pull requests from a GitHub organization and repository that the user has not belonged to for a long time and cannot access.

The entry appears in the Pull Requests list under Previously reviewed. Opening it in Codex reports that the user is not a member of the organization and cannot access the repository.

The user only recently started using Codex, so these entries do not correspond to recent Codex activity. The repository and pull request are also inaccessible directly on GitHub.

Steps to reproduce

1. Open Codex Desktop on macOS.
2. Open the Pull requests section.
3. Find a stale pull request from an organization the authenticated GitHub account no longer belongs to.
4. Open the pull request.
5. Observe that Codex reports that the user is not a member of the organization and has no access.

Expected behavior

The Pull Requests list should only show pull requests that are currently accessible to the authenticated GitHub account, or clearly mark inaccessible historical entries and provide a way to remove or refresh them.

Actual behavior

An inaccessible pull request remains in the list and appears actionable. Opening it leads to an access/membership error.

Impact

This is confusing because the list suggests that the pull request can be reviewed, while the repository is not available to the user. There may be multiple stale entries from organizations the user left long ago.
