## Why
`TurnHandle.run()` returned the raw app-server `Turn`, whose live
start/completed payloads do not include loaded `items`, so users saw
empty `items` after starting a turn. That made the handle-based path
behave differently from `Thread.run(...)`, and pushed examples toward
persisted-thread reads plus helper extraction.
This PR makes the run APIs standalone: starting a turn and running it
returns collected turn data directly, or fails visibly when required
stream events are missing.
## What Changed
- Replaces the public `RunResult` export with `TurnResult`.
- Adds turn metadata to `TurnResult`: `id`, `status`, `error`,
`started_at`, `completed_at`, and `duration_ms`, alongside
`final_response`, `items`, and `usage`.
- Changes `TurnHandle.run()` and `AsyncTurnHandle.run()` to consume
stream events with the same collector used by `Thread.run(...)`.
- Exports `TurnError` from `openai_codex.types` for the new result
shape.
- Updates tests, examples, docs, and the walkthrough notebook to use
`result.final_response` and `result.items` directly.
- Removes persisted-thread helper paths and placeholder/skipped control
flows from the public examples and notebook.
## Verification
- `python3 -m py_compile ...` over changed SDK, example, and test Python
files.
- `python3 -c "import json;
json.load(open('sdk/python/notebooks/sdk_walkthrough.ipynb'))"`
- `git diff --check`
- `PYTHONPATH=sdk/python/src python3 -c ...` import/signature smoke for
`TurnResult`, `TurnHandle.run`, and `AsyncTurnHandle.run`.
Python SDK Examples
Each example folder contains runnable versions:
sync.py(public sync surface:Codex)async.py(public async surface:AsyncCodex)
All examples intentionally use only public SDK exports from openai_codex
and openai_codex.types.
Prerequisites
- Python
>=3.10 - Install SDK dependencies for the same Python interpreter you will use to run examples
Recommended setup (from sdk/python):
uv sync
source .venv/bin/activate
When running examples from this repo checkout, the SDK source uses the local
tree and does not bundle a runtime binary. The helper in examples/_bootstrap.py
uses the installed openai-codex-cli-bin runtime package.
If the pinned openai-codex-cli-bin runtime is not already installed, the bootstrap
will download the matching GitHub release artifact, stage a temporary local
openai-codex-cli-bin package, install it into your active interpreter, and clean up
the temporary files afterward.
The pinned runtime version comes from the SDK package dependency.
Run examples
From sdk/python:
python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py
The examples bootstrap local imports from sdk/python/src automatically, so no
SDK wheel install is required. You only need the Python dependencies for your
active interpreter and an installed openai-codex-cli-bin runtime package (either
already present or automatically provisioned by the bootstrap).
