## Why Reverts #20689 to restore the previous optional state DB plumbing. The conflict resolution keeps the newer installation ID and session/thread identity changes that landed after #20689, while removing the mandatory state DB and agent graph store dependency from ThreadManager construction. ## What changed - Restored `Option<StateDbHandle>` through app-server, MCP server, prompt debug, and test entry points. - Removed the `codex-core` dependency on `codex-agent-graph-store` and reverted descendant lookup back to the existing state DB path when available. - Kept newer `installation_id` forwarding by passing it beside the optional DB handle. - Kept local thread-name updates working when the optional state DB handle is absent. ## Validation - `git diff --check` - `cargo test -p codex-thread-store` - `cargo test -p codex-state -p codex-rollout -p codex-app-server-protocol` - Attempted `env CARGO_INCREMENTAL=0 cargo test -p codex-core -p codex-app-server -p codex-app-server-client -p codex-mcp-server -p codex-thread-manager-sample -p codex-tui`; blocked locally by a rustc ICE while compiling `v8 v146.4.0` with `rustc 1.93.0 (254b59607 2026-01-19)` on `aarch64-apple-darwin`.

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.
