UCP distribution is preview. A seller is not live until the hosted profile, negotiated capabilities, merchant setup, payment handling, order lifecycle, and provider approval have all passed production verification.
Business profile
Darwin will publish an eligible seller profile from the canonical Supply business. The profile must use verified business identity and public URLs and advertise only supported protocol versions and capabilities.
Commerce services
The seller gateway maps checkout and order behavior to Darwin’s canonical deals, transactions, fulfillment, and outcomes. REST is the initial transport; MCP support remains separately gated.
External readiness
Google Merchant Center, supported payment handling, webhook delivery, and provider approval are separate checks. A catalog can be healthy in Darwin while one of these external requirements remains incomplete.
Reconciliation
External order identifiers must remain correlated with privacy-safe Darwin order and transaction keys. Retries must be idempotent, and conflicting state must surface for operator review instead of silently overwriting the canonical record.
