# FrameworkInterrupt

> One framework's human-in-the-loop primitive, and nothing else (SPEC-v0.5 §2.1).

`ctrlrun.FrameworkInterrupt` — class, defined at `src/ctrlrun/adapter.py:179`

```python theme={null}
class FrameworkInterrupt(Protocol)
```

One framework's human-in-the-loop primitive, and nothing else (SPEC-v0.5 §2.1).

`interrupt()` **may exit non-locally**: LangGraph's raises, the graph catches it and
checkpoints, and the resumed run re-enters here and returns. The provider never catches it.

An `interrupt()` that raises anything else is that framework's failure and not a decision.
Nothing is written and it propagates. There is no default, and in particular no default
`granted=False`: a denial is a human's answer, and manufacturing one from a crashed
interrupt puts a refusal in the evidence log that nobody made.
