Where checkout changed
Commerce pages that only explain recommendation capability still leave buyers unsure whether the next purchase will be easier.
Product pages should expose price, inventory, delivery, tax, returns, and preference memory so the next decision is faster.
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
- Add a reusable product-fact card to `ai-ecommerce` and this issue's commerce links
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Without reusable product facts, recommendations remain disposable content. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
