+You can read any PR state you need for monitoring. Writes must comply with this policy.

+You can push PRs to update the code under review or to force CI re-runs as described above.

+You can resolve review comment threads from the human who requested babysitting or from the Codex
+review bot. When resolving, leave a comment prefixed with `[from Codex]: ` and explain what changes
+you made and which commit includes them. Don't touch review threads if other humans other than the

+Before making any changes, fetch the PR state yourself instead of relying on the PR watcher script's

+* resolve review threads from humans other than the user

+description: Choose Rust types for operating system paths across the Codex repository. Use when defining new path-bearing types or explicitly migrating existing ones.
+---
+
+# Path Types
+
+Apply this guidance when defining new types. Change existing code only when explicitly requested,
+and keep edits minimal and proportional. Treat these rules as the target state of an ongoing
+migration; if compliance is difficult, ask the user how to proceed.
+
+- In app-server protocol types, use `LegacyAppPathString` for backwards compatibility during the URI
+  migration. At the protocol boundary, convert it to `PathUri` and use `PathUri` internally. For
+  host-local logic, such as some config values, use `AbsolutePathBuf` or `PathBuf` instead.
+- In exec-server protocol types, use `PathUri`. Internally, use `PathUri` or `AbsolutePathBuf` as
+  appropriate.
+- In dependencies shared by both servers, use `PathUri` or separate APIs that decouple their use
+  cases.
+- Tool call arguments that the model is expected to generate should be deserialized as regular
+  `String`s with feature-specific path handling code.
+
+## Migration requirements
+
+Keep these requirements in mind while migrating code to conform with the above guidelines:
+
+* existing app-server clients keep sending and receiving legacy native-path strings
+* app-server can retain and manipulate foreign-platform path URIs
+* exec-server APIs use file:// URIs
+* local-only operation must not change model-visible text
+* model tool arguments may contain raw relative or absolute paths for any OS
+* path reasoning must work before the related environment has come online
+* URIs cannot explicitly encode the executor’s path convention or operating system
+* users must not configure the environment’s OS/path convention explicitly
+* URIs should not yet be stored in rollouts, databases, or other persistent storage
+* path conversion errors: fail-closed for security-relevant paths, fail-open for UI/diagnostics
+* prefer small focused methods on `PathUri` or `LegacyAppPathString` over local helpers
+
+It is OK if the conversion between paths and URIs is somewhat lossy as long as it will do the right
+thing for real users.
+
+Migrating to URIs should not add significant new failure modes. We will need to surface errors in
+some places that were previously infallible but it should be kept to a minimum.

 description: How to run tests using remote executor.
 ---
 
-Some codex integration tests support a running against a remote executor.
-This means that when CODEX_TEST_REMOTE_ENV environment variable is set they will attempt to start an executor process in a docker container CODEX_TEST_REMOTE_ENV points to and use it in tests.
+Some Codex integration tests select `local`, `docker`, or `wine-exec` through
+`CODEX_TEST_ENVIRONMENT`. The legacy `CODEX_TEST_REMOTE_ENV=<container>` still
+selects Docker; otherwise execution is local.
 
 Docker container is built and initialized via ./scripts/test-remote-env.sh
 
-Currently running remote tests is only supported on Linux, so you need to use a devbox to run them
+On x86-64 Linux, run Wine exec with
+`bazel test //codex-rs/core:core-all-wine-exec-test --test_output=errors`.
+Temporary blockers belong beside the test in `skip_if_wine_exec!` calls.
 
 You can list devboxes via `applied_devbox ls`, pick the one with `codex` in the name.
 Connect to devbox via `ssh <devbox_name>`.

+              foreign-language quotations in an otherwise English issue as requiring translation.
+            - When translation is required, translate the complete title and body into clear,
+              faithful English without answering the issue, adding commentary, or summarizing it.
+            - Preserve Markdown structure, code blocks, inline code, URLs, @mentions, issue
+              references, and technical identifiers. Keep the translated title within GitHub's
+              256-character title limit.
+            - Return the complete English title and body in `translated_title` and
+              `translated_body`. Text that is already English should remain unchanged.
+            - When translation is not required, return empty strings for both translation fields.

 - Avoid bool or ambiguous `Option` parameters that force callers to write hard-to-read code such as `foo(false)` or `bar(None)`. Prefer enums, named methods, newtypes, or other idiomatic Rust API shapes when they keep the callsite self-documenting.
 - When you cannot make that API change and still need a small positional-literal callsite in Rust, follow the `argument_comment_lint` convention:
   - Use an exact `/*param_name*/` comment before opaque literal arguments such as `None`, booleans, and numeric literals when passing them by position.
+  - A method's sole non-self argument is exempt when the method and parameter names match, such as `.enabled(false)` for `fn enabled(&self, enabled: bool)`.
   - Do not add these comments for string or char literals unless the comment adds real clarity; those literals are intentionally exempt from the lint.
   - The parameter name in the comment must exactly match the callee signature.
   - You can run `just argument-comment-lint` to run the lint check locally. This is powered by Bazel, so running it the first time can be slow if Bazel is not warmed up, though incremental invocations should take <15s. Most of the time, it is best to update the PR and let CI take responsibility for checking this (or run it asynchronously in the background after submitting the PR).

-# Codex CLI (Rust Implementation)
+# Codex CLI
 
-We provide Codex CLI as a standalone executable to ensure a zero-dependency install.
-
-## Installing Codex
-
-Today, the easiest way to install Codex is via `npm`:
-
-```shell
-npm i -g @openai/codex
-codex
-```
-
-You can also install via Homebrew (`brew install --cask codex`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).
-
-## Documentation quickstart
-
-- First run with Codex? Start with [`docs/getting-started.md`](../docs/getting-started.md) (links to the walkthrough for prompts, keyboard shortcuts, and session management).
-- Want deeper control? See [`docs/config.md`](../docs/config.md) and [`docs/install.md`](../docs/install.md).
-
-## What's new in the Rust CLI
-
-The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
-
-### Config
-
-Codex supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`docs/config.md`](../docs/config.md) for details.
-
-### Model Context Protocol Support
-
-#### MCP client
-
-Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#connecting-to-mcp-servers) for details.
-
-#### MCP server (experimental)
-
-Codex can be launched as an MCP _server_ by running `codex mcp-server`. This allows _other_ MCP clients to use Codex as a tool for another agent.
-
-Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
-
-```shell
-npx @modelcontextprotocol/inspector codex mcp-server
-```
-
-Use `codex mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `codex mcp-server` to run the MCP server directly.
-
-### Notifications
-
-You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](../docs/config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS. When Codex detects that it is running under WSL 2 inside Windows Terminal (`WT_SESSION` is set), the TUI automatically falls back to native Windows toast notifications so approval prompts and completed turns surface even though Windows Terminal does not implement OSC 9.
-
-### `codex exec` to run Codex programmatically/non-interactively
-
-To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. If you provide both a prompt argument and piped stdin, Codex appends stdin as a `<stdin>` block after the prompt so patterns like `echo "my output" | codex exec "Summarize this concisely"` work naturally. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
-Use `codex exec --ephemeral ...` to run without persisting session rollout files to disk.
-
-### Experimenting with the Codex Sandbox
-
-To test to see what happens when a command is run under the sandbox provided by Codex, use the `sandbox` subcommand in Codex CLI:
-
-```
-# Uses the sandbox implementation for the current host OS:
-# Seatbelt on macOS, the Linux sandbox on Linux, and Windows restricted token on Windows.
-codex sandbox [COMMAND]...
-
-# macOS-only diagnostic option
-codex sandbox --log-denials [COMMAND]...
-```
-
-`codex sandbox` also accepts `--profile NAME` (`-p NAME`) to layer
-`$CODEX_HOME/NAME.config.toml` onto the base user config for the sandboxed
-command.
-
-### Selecting a sandbox policy via `--sandbox`
-
-The Rust CLI exposes a dedicated `--sandbox` (`-s`) flag that lets you pick the sandbox policy **without** having to reach for the generic `-c/--config` option:
-
-```shell
-# Run Codex with the default, read-only sandbox
-codex --sandbox read-only
-
-# Allow the agent to write within the current workspace while still blocking network access
-codex --sandbox workspace-write
-
-# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
-codex --sandbox danger-full-access
-```
-
-In `workspace-write`, Codex also includes `~/.codex/memories` in its writable roots so memory maintenance does not require an extra approval.
-
-## Code Organization
-
-This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:
-
-- [`core/`](./core) contains the business logic for Codex. Ultimately, we hope this becomes a library crate that is generally useful for building other Rust/native applications that use Codex.
-- [`exec/`](./exec) "headless" CLI for use in automation.
-- [`tui/`](./tui) CLI that launches a fullscreen TUI built with [Ratatui](https://ratatui.rs/).
-- [`cli/`](./cli) CLI multitool that provides the aforementioned CLIs via subcommands.
-
-If you want to contribute or inspect behavior in detail, start by reading the module-level `README.md` files under each crate and run the project workspace from the top-level `codex-rs` directory so shared config, features, and build scripts stay aligned.
