Async Python Execution Flow

Trace and implement a closure that reads and updates captured state after its outer function has returned.

Predict the enter, `yield`, body, and `finally` cleanup sequence of an `@contextmanager` on both normal and exceptional exits.

Trace a coroutine from creation through startup, suspension at each `await`, resumption, and return.

Predict the print order when tasks created with `asyncio.create_task()` interleave at explicit suspension points under the event loop's cooperative scheduling model.

Predict both execution order and input-aligned result order for coroutines run with `asyncio.gather()`.

Predict the setup, `yield`, body, and `finally` cleanup sequence of an `@asynccontextmanager` containing suspension points, including an exceptional block exit.

Implement an `@asynccontextmanager` that yields a closure for creating and tracking tasks, then awaits all tracked tasks in a `finally` path before exit.

Predict each task's `ContextVar` values by applying task-creation snapshot inheritance and token-based `reset()` semantics.

Implement a `ContextVar`-based recorder that installs fresh per-run state, restores caller state in `finally`, and keeps concurrent runs isolated when coordinated with `asyncio.gather()`.
