An archived product disappears from the lists (GET /api/v1/loan-products?archived=true lists them) and cannot originate a new contract; contracts already written, their history and their later tranches are untouched. Unarchiving restores the status the product left: active on the same pinned version, or draft when it never had one. Asking for the state the product already has answers 200 and writes nothing. Activating an archived product is refused 409 LENDER-0133. ## OpenAPI ````yaml /pt/openapi/v3-current/lender.yaml put /api/v1/loan-products/{id}/archived openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- Code-first OpenAPI 3.1 surface for the Lender service.
