Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Address entry | Choose address entry when the product needs a complete postal, delivery, billing, contact, or official address rather than one short freeform value. | Users can start with lookup or choose manual entry before providing a postal code. | Google supports editable fields after autocomplete, address validation correction states, unit review, and acceptance logic for imperfect validation. |
| Checkout | Choose checkout when the primary task is completing a purchase or order from selected items or priced services. | Changing quantity, address, delivery method, discount, or payment route updates the order summary and total before commit. | Google address validation checkout guidance supports address validation as a checkout subtask affecting delivery reliability. |
