Shaqayeq fc75d07504 Add Python SDK public API and examples (#14446)
## TL;DR
WIP esp the examples

Thin the Python SDK public surface so the wrapper layer returns
canonical app-server generated models directly.

- keeps `Codex` / `AsyncCodex` / `Thread` / `Turn` and input helpers,
but removes alias-only type layers and custom result models
- `metadata` now returns `InitializeResponse` and `run()` returns the
generated app-server `Turn`
- updates docs, examples, notebook, and tests to use canonical generated
types and regenerates `v2_all.py` against current schema
- keeps the pinned runtime-package integration flow and real integration
coverage

  ## Validation
  - `PYTHONPATH=sdk/python/src python3 -m pytest sdk/python/tests`
- `GH_TOKEN="$(gh auth token)" RUN_REAL_CODEX_TESTS=1
PYTHONPATH=sdk/python/src python3 -m pytest sdk/python/tests -rs`

# Getting Started
This is the fastest path from install to a multi-turn thread using the public SDK surface.
The SDK is experimental. Treat the API, bundled runtime strategy, and packaging details as unstable until the first public release.
## 1) Install
From repo root:
```bash
cd sdk/python
python -m pip install -e .
```
Requirements:
- Python `>=3.10`
- installed `codex-cli-bin` runtime package, or an explicit `codex_bin` override
- local Codex auth/session configured
## 2) Run your first turn (sync)
```python
from codex_app_server import Codex, TextInput
with Codex() as codex:
server = codex.metadata.serverInfo
print("Server:", None if server is None else server.name, None if server is None else server.version)
thread = codex.thread_start(model="gpt-5.4", config={"model_reasoning_effort": "high"})
completed_turn = thread.turn(TextInput("Say hello in one sentence.")).run()
print("Thread:", thread.id)
print("Turn:", completed_turn.id)
print("Status:", completed_turn.status)
print("Items:", len(completed_turn.items or []))
```
What happened:
- `Codex()` started and initialized `codex app-server`.
- `thread_start(...)` created a thread.
- `turn(...).run()` consumed events until `turn/completed` and returned the canonical generated app-server `Turn` model.
- one client can have only one active `TurnHandle.stream()` / `TurnHandle.run()` consumer at a time in the current experimental build
## 3) Continue the same thread (multi-turn)
```python
from codex_app_server import Codex, TextInput
with Codex() as codex:
thread = codex.thread_start(model="gpt-5.4", config={"model_reasoning_effort": "high"})
first = thread.turn(TextInput("Summarize Rust ownership in 2 bullets.")).run()
second = thread.turn(TextInput("Now explain it to a Python developer.")).run()
print("first:", first.id, first.status)
print("second:", second.id, second.status)
```
## 4) Async parity
Use `async with AsyncCodex()` as the normal async entrypoint. `AsyncCodex`
initializes lazily, and context entry makes startup/shutdown explicit.
```python
import asyncio
from codex_app_server import AsyncCodex, TextInput
async def main() -> None:
async with AsyncCodex() as codex:
thread = await codex.thread_start(model="gpt-5.4", config={"model_reasoning_effort": "high"})
turn = await thread.turn(TextInput("Continue where we left off."))
completed_turn = await turn.run()
print(completed_turn.id, completed_turn.status)
asyncio.run(main())
```
## 5) Resume an existing thread
```python
from codex_app_server import Codex, TextInput
THREAD_ID = "thr_123" # replace with a real id
with Codex() as codex:
thread = codex.thread_resume(THREAD_ID)
completed_turn = thread.turn(TextInput("Continue where we left off.")).run()
print(completed_turn.id, completed_turn.status)
```
## 6) Generated models
The convenience wrappers live at the package root, but the canonical app-server models live under:
```python
from codex_app_server.generated.v2_all import Turn, TurnStatus, ThreadReadResponse
```

- Common decisions/pitfalls: `docs/faq.md`
- End-to-end runnable examples: `examples/README.md`
