Publish a video

The two-step flow

1. Prepare: publish_video without confirmations returns per-platform previews: derived aspect ratio, a caption draft in the platform's style, and hashtags trimmed to the platform's conventions. Nothing posts.
2. Confirm: call again with confirmations naming each platform you approve. Only platforms with confirm: true post; unconfirmed platforms are skipped.

{
  "asset_id": "…",
  "confirmations": [
    { "platform": "tiktok", "confirm": true },
    { "platform": "youtube", "confirm": true }
  ]
}

The two gates

• Safety gate: an asset without a provenance manifest cannot be published at all.
• Confirm gate: posting is never autonomous. No confirmation, no post.

Per-platform results

Each platform returns its own success or failure; one platform failing never drops the others. Every publish is written to the audit log.
