### API

```python
nemo_gym.sandbox.providers.opensandbox.failures.opensandbox_failure(
    operation: str,
    sandbox_id: str | None = None,
    cause: BaseException | None = None,
    failure_kind: str | None = None,
    reason: str | None = None,
    execution_id: str | None = None,
    provider_status_reason: str | None = None,
    exit_code: int | None = None,
    http_status: int | None = None
) -> nemo_gym.core.typed_exceptions.NgFailureEvent
```

Classify this operation's evidence, then construct its sandbox event.

Message text cannot establish OOM, credentials rejection, command termination,
or safe command replay. Callers raise the event `from cause`.
