WHY IT NEEDS A POLICY

Why swarmtrade_announce_asset needs a policy

This tool creates a new marketplace listing by registering an asset. It is a write operation (create/post) that adds data to the marketplace. While it operates in a financial/trading context, it does not itself move money or commit financial obligations—it only makes an asset discoverable for potential trades.
