## Why `TurnDiffTracker` computes a display root so turn diffs can be rendered repo-relative. For remote exec-server turns, the selected turn `cwd` may exist only inside the selected environment, but `run_turn` was discovering the git root through the local host filesystem. When that lookup failed, nested remote-session diffs fell back to the nested `cwd` and showed `/tmp/...`-prefixed paths instead of repo-relative paths. ## What changed - Resolve the diff display root from the primary selected turn environment when one exists, using that environment's filesystem and `cwd`. - Add `codex_git_utils::get_git_repo_root_with_fs(...)` so git-root discovery can run against an `ExecutorFileSystem`, including remote environments. - Reuse that helper from `resolve_root_git_project_for_trust(...)` and add coverage for `.git` gitdir-pointer detection. ## Validation - Devbox Bazel: `//codex-rs/core:core-unit-tests --test_filter=get_git_repo_root_with_fs_detects_gitdir_pointer` - Devbox Docker-backed remote-env repro: `//codex-rs/core:core-all-test --test_filter=apply_patch_turn_diff_paths_stay_repo_relative_when_session_cwd_is_nested`
npm i -g @openai/codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
