# Interrupt handler

## Functions

### InterruptHandler()

```ts theme={null}
function InterruptHandler(): Element | null;
```

Defined in: [components/assistant-ui/interrupt-handler.tsx:68](https://github.com/corovcam/Universal-Object-Mapping/blob/main/frontend/uom-translator-ui/components/assistant-ui/interrupt-handler.tsx#L68)

React Component to handle the LangGraph suspended (interrupted) state.

Intercepts the human-in-the-loop validation checkpoint raised by the backend
`human_intervention_node` via LangGraph's native `interrupt()` API. The payload
(instruction + current translation state + query-equivalence deep diffs) is
surfaced through `useLangGraphInterruptState()`. The user can Accept the
translation or Reject it with targeted feedback; the decision is resumed back
into the graph with `Command(resume={ decision, feedback })`.

The interrupt is captured live (requires `"updates"` in the stream's `streamMode`)
and restored on reload via the runtime's `load()` callback, so the card reappears
when an interrupted conversation is reopened from the thread list.

#### Returns

`Element` | `null`

The interrupt control card, or null if execution is not suspended.
