# NotExecuted

> Raised by an executor to assert the remote side did nothing (SPEC-v0.1 §5.5).

`ctrlrun.NotExecuted` — class, defined at `src/ctrlrun/errors.py:157`

```python theme={null}
from ctrlrun import NotExecuted
```

```python theme={null}
class NotExecuted(CTRLRunError)
```

Raised by an executor to assert the remote side did nothing (SPEC-v0.1 §5.5).

This is the *only* exception that maps to `FAILED` and therefore permits a retry.
Every other exception is an `AMBIGUOUS` outcome.
