Fixes #15219. ## Why `thread/resume` should continue a persisted thread with the same model provider that created the thread. The app server already restores the persisted model and reasoning effort before resuming, but it was leaving `model_provider` unset. If a user created a thread with one provider and later switched their active profile to another provider, resumed encrypted history could be sent to the wrong endpoint and fail with `invalid_encrypted_content`. The thread metadata already records the original provider, so resume should apply it when the caller has not explicitly requested a different model/provider/reasoning configuration. ## What changed This updates `merge_persisted_resume_metadata` in `app-server/src/codex_message_processor.rs` to copy `ThreadMetadata::model_provider` into `ConfigOverrides::model_provider` alongside the persisted model. The existing resume metadata tests now also assert that: - the persisted provider is restored for normal resume - explicit model, provider, or reasoning-effort overrides still prevent persisted resume metadata from being applied - a thread with no persisted model or reasoning effort still resumes with its persisted provider ## Verification - `cargo test -p codex-app-server` passed the app-server unit tests, including the updated resume metadata coverage. The broader integration portion of that command failed in an unrelated environment-sensitive skills-budget warning assertion, where this run saw 8 omitted skills instead of the expected 7. - `just fix -p codex-app-server` completed successfully.

npm i -g @openai/codex
or brew install --cask codex
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.
