preflight-guard
One-call pre-transaction guard for agents: bundle the transaction you're about to sign/send and get every applicable safety check in a single payment — signature-intent decode, live threat-DB + address-poisoning look-alike on the recipient, and a drainer audit of standing approvals. By design no combined safe/danger verdict is emitted; each sub-check's flags & evidence come back verbatim so your agent decides. Replaces 4 separate 402 round-trips with 1. Deterministic, no LLM.
