WHY IT NEEDS A POLICY

Why convert_to_assets needs a policy

Converting wrapped tokens to their underlying asset is a Write operation—it modifies the user's token balances and positions. While reversible (they could convert back), it commits a financial exchange on a blockchain. Given the financial context (trading protocol on BNB Smart Chain) and the potential for significant value transfer, severity is high.

From the tool's definition Tool performs 'convert_to_assets' which transforms wSTASIS shares into STASIS value, a reversible conversion/swap operation that modifies token holdings.
