# transcript

The structured transcript captured while producing the value, if any.

```
var transcript: StructuredTranscript? { get }
```

## Discussion

Subjects backed by a language model session expose the session transcript here;
subjects that don’t involve a model leave it `nil` (the default). The
transcript-attachment recorder reads this through the type-erased results column,
so any subject type that carries one participates automatically.
