MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill is a Stellar-specific crypto subsystem (StrKey encoding/decoding, Stellar StrKey version bytes, SignerKey types, preAuthTxKey(TransactionFrame), SecretKey::sign, ed25519-signed-payload signer keys, etc.). These are explicit, domain-specific primitives used to create/encode/sign Stellar transactions and pre-authorized transaction signer keys — i.e., direct blockchain/crypto signing and key-management functionality tied to a payment ledger. This is not just a generic crypto toolkit; it contains explicit blockchain transaction-signing and Stellar wallet/key formats, which enable direct financial transaction execution.
