## Why `ThreadConfigSnapshot` is used by app-server and thread metadata code as a stable view of active runtime settings. Keeping both `sandbox_policy` and `permission_profile` in the snapshot duplicates permission state and makes it possible for the legacy projection to drift from the canonical profile. The legacy `sandbox` value is still needed at app-server compatibility boundaries, so this PR derives it on demand from the snapshot profile and cwd instead of storing it. ## What Changed - Removes `ThreadConfigSnapshot.sandbox_policy`. - Adds `ThreadConfigSnapshot::sandbox_policy()` as a compatibility projection from `permission_profile` plus `cwd`. - Updates app-server response/metadata code and tests to call the projection only where legacy fields still exist. - Keeps snapshot construction profile-only so split filesystem rules, disabled enforcement, and external enforcement remain represented by the canonical profile. ## Verification - `cargo test -p codex-app-server thread_response_permission_profile_preserves_enforcement --lib` - `cargo test -p codex-core dispatch_reclaims_stale_global_lock_and_starts_consolidation --lib` --- [//]: # (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.
