## Why Login already honors `respect_system_proxy`, but several login-owned auth flows still construct and pass around raw `reqwest::Client` values. That keeps those request paths coupled to the underlying transport and leaves `codex-login` on the temporary direct-`reqwest` allowlist introduced by #31431. Auth endpoints also have a stricter logging boundary than ordinary API requests: custom issuer URLs and response headers may contain credentials. Moving these requests behind the shared HTTP abstraction must preserve that boundary while retaining route-aware proxy and custom-CA behavior. This is a bounded login migration. The separate Agent Identity and shared default-client compatibility migrations remain follow-up work. ## What changed - Add `HttpClientFactory::build_client` to construct the shared `HttpClient` abstraction for a resolved destination and route class. - Add a route-aware construction path that suppresses request URL, response-header, and transport-error diagnostics for sensitive auth endpoints. - Route device-code user-code/polling requests, OAuth authorization-code exchange, and API-key token exchange through `HttpClient`. - Build the revoke timeout test client through the same factory API. - Use the transport-neutral `http::StatusCode` in the migrated device-code flow. - Add an end-to-end log-capture regression test covering successful responses and transport failures after `RequestBuilder` transformations. ## Review guidance The request behavior is intended to be unchanged: each issuer/token endpoint selects the same auth route, including the existing system/PAC proxy and custom-CA handling, and raw auth clients still omit Codex default headers. The intentional logging change is limited to raw auth requests, whose URL userinfo, query credentials, response headers, and transport errors must not cross the auth redaction boundary. This PR deliberately does **not** remove `codex-login` from #31431's allowlist. The remaining direct `reqwest` surface belongs primarily to: - Agent Identity APIs that still accept `reqwest::Client`. - Exported default-client compatibility helpers used by other workspace crates. - A small number of tests and concrete error/header types. ## Testing - `cargo check -p codex-http-client -p codex-login --tests` - `just test -p codex-http-client` (41 tests) - `just test -p codex-login` (155 tests) - `just bazel-lock-check` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
