# Visual Schema

Every visual result includes:

- `asset_id`
- `view_type`
- `lens_name`
- `lens_version`
- `parameters_hash`
- `confidence`
- `payload_json`
- `provenance_json`

Derived views are cached by:

    sha256(asset bytes) + lens name + lens version + canonicalized parameters

This lets a later text-only turn reuse previous visual evidence without re-uploading or recomputing the image.
