Conflict (idempotency body mismatch, duplicate adjustment, or an unsupported provider capability). Unsupported mutations return BILLING.PAYMENT_PROVIDER_CAPABILITY_UNSUPPORTED before Customer creation, provider I/O, or local state mutation. Concurrent use of the same Idempotency-Key returns WRITE.IDEMPOTENCY_IN_PROGRESS; different keys are independent requests whose final ordering is owned by the PSP. A subscription Checkout with mixed group, currency, or recurrence facts is rejected before Customer lookup or provider I/O. Missing or inconsistent selected Customer bindings return BILLING.PAYMENT_PROVIDER_CUSTOMER_REQUIRED or BILLING.PAYMENT_PROVIDER_CUSTOMER_CONFLICT without silently replacing the binding.
