qualifier token a chosen word

credit type

The kind of pay-over-time arrangement an instalment plan is — a financed purchase or a lease. A qualifier of `installment_plan` (cardinality one). A governed token whose value-domain is exactly Google Merchant's installment.credit_type (finance / lease — the spec admits no others), growing only if a real new financing structure appears (L13). Buy-now-pay-later is NOT a value here: whether a SKU is offered BNPL and via which provider (Klarna/Affirm/Afterpay) is per-seller checkout-integration data that varies by who sells the identical SKU (A6, the b76 fulfilment_program precedent) — held downstream, not a pool value or a credit_type member.

Credit type is answered with one word chosen from the credit types list — the same word shared across every product that uses it.

It is a qualifier of instalment plan — it has meaning only inside a instalment plan statement, one per statement, never on its own. It belongs with instalment plan to subscription & financing — one facet of a product.

It is answered inside every instalment plan statement, not as a standalone question on a kind.
