Note

Medium Risk
Adds payment and vault-item surface area (enrollment links, method removal, purchase funding binding); mostly additive OpenAPI-generated types but affects how integrators model wallets and checkout.

Overview
Release 0.133.0 extends the vault API for multi-card Kernel wallets and wallet-scoped purchases.

Callers can manage cards on a connected Kernel wallet via new vault item operations add_payment_method (hosted card enrollment link) and remove_payment_method (payment_method_id), with typed request/result models and perform_operation overloads on sync/async ItemsResource. VaultPaymentMethod now carries enrollment status, optional action/expires_at, and clearer default-card semantics.

A new payment_request vault item type (Link and Kernel specs) models purchases parented by a wallet, with upsert / update support alongside existing card/credential flows. Kernel card specs and state gain optional payment_method_id and funding_status so purchases are bound to a specific wallet payment method. Docs and credential guidance now steer checkout toward wallet, payment_request, and card items instead of credentials alone.
