Composition and publish gates

Composition happens before publication. Any draft slideshow, video, or text output can be selected as input to another compatible template. The next generation records both the processor template and its source outputs.

{
  "templateId": "astrology-slideshow",
  "inputOutputIds": ["research-text-output"],
  "outputIds": ["generated-slideshow"],
  "status": "ready"
}

Outputs remain composable until they enter a publish gate. The gate owns destination-specific fields such as caption, description, hashtags, accounts, and publish timing.

{
  "outputIds": ["generated-slideshow", "caption-text-output"],
  "metadata": {
    "caption": "Which one are you?",
    "description": "A comparison of two zodiac mindsets.",
    "hashtags": ["astrology", "zodiac"]
  },
  "selectedAccountIds": ["threads-account"],
  "mode": "draft"
}

The gate resolves ordered images or video plus any selected text output and creates one publishable post per destination. Draft, schedule, and publish-now are post states; they are not output states.
