This section of code, which pre-populates character references, is susceptible to an arbitrary file read vulnerability. The `primary_reference_image` path is used without validation, allowing for potential upload of arbitrary local files to the FAL AI service if the registry JSON contains absolute or traversal paths. To remediate this, ensure paths are relative and free of directory traversal components. Additionally, consider extracting this reference resolution logic into a private helper method to reduce duplication with `generate_from_shots` and improve maintainability.

```suggestion
                if ref_result.primary_reference and not Path(ref_result.primary_reference).is_absolute() and ".." not in Path(ref_result.primary_reference).parts:
                    shot.primary_reference_image = ref_result.primary_reference
```
