Before you start
Your questions, answered.
Does valid JSON mean fully valid schema?
No. Correct syntax does not verify every schema requirement or rich-result condition. Review content, properties and the rules of the consuming platform.
Does the public button run a task?
You continue to the app with prepared input, then review settings and estimates before running.
