# Validate Twin

> Everything a create checks, for free, without creating anything: the dataset resolves and has video,
which camera will seed the room, and how long a twin typically takes.

Errors name what to fix, with the field in `param`: `dataset_not_found`, `dataset_gated`,
`dataset_has_no_video`, `camera_not_found` (`details.cameras` lists the real ones), `no_suitable_camera`.
