## Summary Bound TUI startup terminal response probes so unsupported terminals cannot stall startup for multiple seconds. This replaces the Unix startup uses of crossterm's blocking response probes with short `/dev/tty` probes that use nonblocking reads and `poll` with a 100ms timeout. It covers the initial cursor-position query, keyboard enhancement support detection, and OSC 10/11 default-color detection. The default-color probe uses one shared deadline for foreground and background instead of allowing two independent full waits. The diagnostic mode/trace env vars from the investigation branch are intentionally not included. The shipped behavior is simply bounded probing by default, while non-Unix keeps the existing crossterm fallback path. ## Details - Add a private `terminal_probe` module for bounded Unix terminal probes and response parsers. - Let `custom_terminal::Terminal` accept a caller-provided initial cursor position so startup can compute it before constructing the terminal. - Use bounded cursor, keyboard enhancement, and default-color probes on Unix startup. - Preserve default-color cache behavior so a failed attempted query does not retry forever. ## Validation - `cd codex-rs && just fmt` - `cd codex-rs && cargo test -p codex-tui terminal_probe` - `cd codex-rs && just fix -p codex-tui` - `cd codex-rs && just argument-comment-lint` - `git diff --check` - `git diff --cached --check` `cd codex-rs && cargo test -p codex-tui` still aborts on the pre-existing local stack overflow in `app::tests::discard_side_thread_keeps_local_state_when_server_close_fails`; I reproduced that same focused failure on `main` before this PR work, so it is not introduced by this change. Manual validation in the VM showed the original crossterm path taking about 2s per unanswered probe, while bounded probing returned in about 100ms per probe.

npm i -g @openai/codex
or brew install --cask 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.
