WHY IT NEEDS A POLICY

Why trigger_url_ingest needs a policy

This tool fetches an external URL and uploads/ingests the asset into the platform, which is a write operation (creating a new asset record). It does not delete or overwrite existing data, execute arbitrary code, or involve financial transactions. Misuse could result in ingesting unwanted or malicious content into the platform, warranting medium severity.
