Given an address: is it a Gnosis Safe, its owners and M-of-N threshold, version, activity, and — critically — its enabled MODULES. A module can move the Safe's funds via execTransactionFromModule with no owner signatures, so each one is an address with unilateral control. Returns a multisig / single_signer / has_modules verdict: the counterparty check before you trust funds to a multisig. address= required.
