> Canonical hosted-video and VAST contracts for CTV, SSAI, CSAI, and companion experiences.

CTV uses the standard `video_hosted` and `video_vast` canonicals. SSAI/CSAI mode, app environment, ad-pod position, measurement availability, and inventory guarantees belong on the product or placement.

```json theme={null}
{
  "publisher_domain": "tv.streamhaus.example",
  "format_option_id": "ctv_ssai_30s",
  "format_kind": "video_hosted",
  "params": {
    "width": 1920,
    "height": 1080,
    "duration_ms_exact": 30000,
    "containers": ["mp4"],
    "video_codecs": ["h264"],
    "audio_codecs": ["aac"],
    "slots": [
      { "asset_group_id": "video_main", "asset_type": "video", "required": true },
      { "asset_group_id": "companion_image", "asset_type": "image", "required": false }
    ]
  }
}
```

For CSAI or third-party delivery, use `video_vast` and a required `vast_tag` slot. A multi-output creative agent may advertise separate SSAI and VAST capability IDs; buyers select them with `target_capability_ids[]` and receive portable canonical manifests.

Preview on the seller/publisher endpoint when device chrome, companion placement, ad-pod context, or remote-control interaction matters. The impression-time CTV renderer remains the seller runtime behind `sync_creatives`.
