Where checkout changed
Stripe Agents place agents, payments, authorization, and business actions in one chain, which makes responsibility boundaries a page-level requirement.
Separate recommendation, quote, tax, payment, refund, support, and dispute handling so the payment action is not hidden inside automation copy.
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
- Connect `ai-saas-payment-en` and `agentic-commerce-checklist-en` to responsibility-layer copy
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
When payment responsibility is vague, smoother automation creates harder disputes later. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
