# Purchase Handoff Maturity Checklist

AI shopping readiness is not complete just because products are discoverable. The shopper must be handed to the right purchasable state.

## Maturity ladder

| Level | Capability | Evidence |
|---:|---|---|
| 0 | No reliable handoff | Agents can describe products but not send users to exact purchasable state |
| 1 | Product URL handoff | Stable canonical product URLs |
| 2 | Product/variant URL handoff | Exact product and variant state visible in URL or page state |
| 3 | Cart deep link or storefront API | Product, variant, quantity, locale/currency can be passed safely |
| 4 | Agent-native handoff | MCP/UCP/ACP or equivalent controlled handoff protocol |
| 5 | Certified monitored integration | Production monitoring, safety, support, and reconciliation processes |

## Current package interpretation

The current sampled audit found useful product-page data, but did not verify an agent-native cart or checkout integration. Treat this as a maturity opportunity, not an immediate defect.

## Safety checks before deeper integration

- Explicit user action required before checkout/payment.
- Rate limits and abuse controls are defined.
- Privacy and consent boundaries are documented.
- Support/reconciliation path exists for failed handoffs.
- Test mode is separated from production.
