# Intelligence layer, fraud, duplicate detection, address patterns

Beyond address validation, Tacey now factors in fraud signals, duplicate-order detection, customer history, trusted/known-bad address caches, and phone sanity validation.

The agent reasons over a richer per-order context: velocity, IP geolocation, browser anomalies, returning vs first-time customer, addresses that previously succeeded or failed, and phone number sanity. Each signal is independently configurable.
