WHY IT NEEDS A POLICY

Why swarmtrade_announce needs a policy

This tool registers/announces an asset for sale, which is a write operation creating a new listing. While it operates within a trading/escrow context, it does not itself move money or commit financial obligations — it only creates a listing record. The blast radius is medium since a misused announcement could create fraudulent or misleading listings on the marketplace.
