Pre-send safety check: is this recipient a known malicious address (caught live on Base seeding address-poisoning via zero-value transfer sprays), or a look-alike of an address you trust? Checks our continuously-updated threat DB + deterministic look-alike logic. Answers an agent's 'is it safe to send here?' before every transfer.
