Why statusline does not display Git branches
I first confirmed the source of the current directory's Git status and statusline configuration:
If the current directory is not a workspace or the command configured to fetch branches fails, the status bar will not display branches.
The Codex itself is the Git workspace, and the current branch can be correctly parsed as cjsybank-20260606. Next, I checked Codex's statusline configuration and logs, focusing on whether the actual executed command fetched this branch.
The configuration already includes git-branch, so the problem is not a missing configuration. Now I will check the statusline initialization logs and Codex version to determine if it is caused by log truncation, version incompatibility, or runtime directory errors.
I have confirmed three times that git-branch is enabled and the current warehouse can fetch branches. Codex version is 0.131.0. I will only paste the statusline initialization log segment to avoid interference from the entire Codex log history.
The troubleshooting direction is now clear: it is not a problem with the warehouse itself or a missing git-branch configuration. I will extract the specific project logs where the status bar truncates information for the last time to confirm whether Codex included this item.
The reasons that can be ruled out:
The current directory is a Git repository.
The current branch can be fetched normally: cjsybank-20260606.
git-branch is already configured in C:\Users\CNJ\.codex\config.toml.
Codex logs also show that the status bar has recognized GitBranch.
So the most likely reason is: the statusline content is too long, and when the terminal width is insufficient, subsequent items are squeezed out or not displayed. In your configuration, git-branch is placed at a relatively rear position.
status_line = ["model-with-reasoning", "context-window-size", "context-used", "used-tokens", "project-name", "git-branch", "run-state"]
The preceding models, context, tokens, and project names already occupy a lot of width. The branch name is also cjsybank-20260606, which cannot be displayed when the window is not wide enough.
It is recommended to move git-branch forward or remove unnecessary items, for example:
toml
[
tui
]
status_line = ["git-branch", "project-name", "model-with-reasoning", "context-used", "run-state"]
Restart Codex TUI after modification. You can also first drag the terminal window to widen it to verify; the branch should appear when the width is sufficient.
Key point: run-state can always display normally [Image #1]
Your previous diagram overturned the "purely width truncation" judgment: run-state is still displayed after git-branch, indicating that the GitBranch item was skipped. Now I will explore why it failed to fetch the branch instead of being truncated.
The sandbox is only executing commands that trigger a Windows runner error. I changed to use elevated permissions to check and verify again whether Codex itself can call Git normally when running, and whether its branch parsing logic depends on a working directory.
The branch itself is fine: git branch --show-current returns cjsybank-20260606, and git status --branch is also normal. The next step is to check if there is no Git information recorded in the Codex session context; if there is no Git information in the context, the status bar will directly receive empty values.
You are right. Ready can be displayed normally, indicating that it is not the subsequent content being truncated, but the git-branch item itself is empty. I will continue to debug locally and check the Codex session context, aiming to confirm whether it only reads the "warehouse information cache" somewhere.
Test results for git-branch: Both git branch --show-current and git status --branch can get cjsybank-20260606, so the empty value is not caused by the Git warehouse itself. Now I want to look at the Codex status bar implementation to confirm how GitBranch obtains values.

Found the key point from the source code: git-branch does not directly take values from the Git executed in the current terminal. Instead, it goes through Codex's workspace_command_runner to asynchronously run git branch --show-current; if it fails, it returns None, and the status bar directly skips this item without reporting an error. Combining with your Windows runner 1312 error, the direction is now very clear.

Yes, your judgment is correct. My previous statement about "width truncation" is not valid.
The actual reason is: run-state is a TUI internal state, directly displayed; git-branch is not an internal state, it will be executed in the background through Codex's app-server / workspace-command.
git branch --show-current
In the source code, this command directly returns None if it fails, and then this section of the status bar is omitted without displaying any errors. Reference: In Codex's branch_summary.rs, git branch --show-current returns empty after failure.
workspace_command.rs indicates that the status bar and other similar commands are sent to app-server/exec.
Your local Git is fine, I verified it:
plaintext
git branch --show-current
But Codex logs show a large number of:
windows sandbox: runner error: CreateProcessAsUserW failed: 1312
So the conclusion is: When fetching branches in the background for the status bar, it uses the Windows sandbox runner, which failed due to a path issue; after failure, git-branch is silently hidden. Ready is not affected because it does not need to call external commands.
Temporary verification method: Start Codex with non-sandbox/full access to see if the branch appears. The trade-off is that tool commands will no longer be restricted by workspace-write. A more stable fix can only be to repair the Codex Windows sandbox runner path, or switch to an environment where this Windows sandbox runner is not triggered.
What are the available options for the sandbox_mode configuration?

When sandbox_mode = "workspace-write", the Git branch name is not displayed; when sandbox_mode = "danger-full-access", it can be displayed normally.
Confirmed still reproducible on Codex CLI 0.147.0 on native Windows (PowerShell), using workspace-write sandboxing. The status line config includes git-branch, and the /statusline picker shows the sample value feat/awesome-feature, but the item disappears immediately after leaving the picker. This is not width truncation: the terminal is over 200 columns wide. The repository and session working directory are correct, and external Git resolves the branch normally: git branch --show-current and git symbolic-ref -q --short HEAD both return main. Reproduces after repeated restarts and with resumed sessions.
