Where checkout changed
Shopping agents are commercially interesting when they help users compare, add to cart, and complete a transaction.
Do not trust one conversion number
The useful question is no longer whether a purchase happened; it is which step created the hesitation, missing fact, or measurement gap.
Check the event model
- Check product data, inventory, payment, returns, and merchant responsibility
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Use this as a signal or index, not as final proof. Verify key facts through official pages or documentation. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
