PR status line does not show open PR even though gh pr view succeeds

Environment

• Codex CLI: codex-cli 0.131.0
• Platform: macOS
• Repository: private GitHub repository
• GitHub CLI is authenticated with an account that has access to the private repository.

Config

~/.codex/config.toml:

[tui]
status_line = [
  "model-with-reasoning",
  "git-branch",
  "context-remaining",
  "five-hour-limit",
  "weekly-limit",
  "pull-request-number",
  "task-progress"
]
status_line_use_colors = true

Reproduction

1. Open Codex CLI in a local branch that has an open GitHub PR.
2. Confirm the PR is discoverable from the same cwd:

gh pr view --json number,url,state,headRefName,headRefOid

Example successful output:

{
  "number": 123,
  "state": "OPEN",
  "url": "https://github.com/<org>/<repo>/pull/123",
  "headRefName": "feature/example-branch",
  "headRefOid": "<head-sha>"
}

1. Confirm it also works with the same prompt-disabled env used by Codex status probes:

env GH_PROMPT_DISABLED=1 GIT_TERMINAL_PROMPT=0 gh pr view --json number,url,state
env GH_PROMPT_DISABLED=1 GIT_TERMINAL_PROMPT=0 /opt/homebrew/bin/gh pr view --json number,url,state

Both return the open PR.

Expected Behavior

The TUI status line should render PR #123 when pull-request-number is enabled.

The Codex App PR panel should also detect the open PR, or report the failed lookup reason.

Actual Behavior

• Codex CLI status line does not show the PR number.
• Codex App shows Pull request status unavailable.
• Manual gh pr view succeeds from the same repo/cwd.

Notes

From the public source, pull-request-number appears to use gh pr view --json number,url,state via the status-line git summary path:

• codex-rs/tui/src/branch_summary.rs
• codex-rs/tui/src/chatwidget/status_surfaces.rs

Since the same command succeeds manually, this looks like the status-line/App PR lookup is not refreshing, not receiving the git summary result, or is using a different execution context than the user shell.
