## Why The app-server thread lifecycle API should no longer expose the full `PermissionProfile` value. After the permissions-profile migration, clients should round-trip only the active profile identity through `activePermissionProfile` and `permissions` when that identity is known. The full profile is server-side config. Treating a response-derived legacy sandbox projection as a new local profile can lose named-profile restrictions and accidentally widen permissions on the next turn. The legacy `sandbox` response field remains only as the compatibility/display fallback. ## What Changed - Removed `permissionProfile` from `ThreadStartResponse`, `ThreadResumeResponse`, and `ThreadForkResponse`. - Stopped populating that field in app-server thread start/resume/fork responses. - Updated embedded exec/TUI response mapping to derive display permission state from local config or the legacy sandbox fallback instead of a response profile value. - Added a TUI turn override shape that distinguishes preserving server permissions, selecting an active profile id, and sending a legacy sandbox for an explicit local override. - Preserved remote app-server permissions across turns by sending `permissions` only when an `activePermissionProfile` id is known, and otherwise sending no sandbox override unless the user selected a local override. - Kept embedded `thread/resume` hydration server-authored when `activePermissionProfile` is absent, which matches the live-thread attach path where the server ignores requested overrides. - Updated the app-server README to remove the obsolete lifecycle response `permissionProfile` reference. The remaining `permissionProfile` README references are request-side permission overrides. - Regenerated app-server JSON schema and TypeScript fixtures. - Kept the generated typed response enum exempt from `large_enum_variant`, matching the existing payload enum exemption after the lifecycle response variants shrank. ## How To Review Start with `codex-rs/app-server-protocol/src/protocol/v2/thread.rs` to confirm the response shape, then check the response construction in `codex-rs/app-server/src/request_processors`. The generated schema and TypeScript fixture changes are mechanical follow-through from the protocol removal. The TUI behavior is the delicate part: review `codex-rs/tui/src/app_server_session.rs` for response hydration and turn-start override projection, then `codex-rs/tui/src/app/thread_routing.rs` for the decision about whether the next turn should preserve the server snapshot, send an active profile id, or send a legacy sandbox for an explicit local override. ## Verification - `just write-app-server-schema` - `cargo test -p codex-app-server-protocol thread_lifecycle_responses_default_missing_optional_fields` - `cargo test -p codex-exec session_configured_from_thread_response_uses_permission_profile_from_config` - `cargo test -p codex-tui --lib thread_response` - `cargo test -p codex-tui turn_permissions_` - `cargo test -p codex-tui resume_response_restores_turns_from_thread_items` - `cargo test -p codex-analytics track_response_only_enqueues_analytics_relevant_responses` - `just fix -p codex-analytics` - `just fix -p codex-app-server-protocol` - `just fix -p codex-tui` - `just argument-comment-lint` --- [//]: # (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
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.
