'obrigacao' is the SAME shape as one element of GET /v1/consignado/saldo-devedor, so a console needs one renderer for both. 'amortizacoes' is the per-competência record of what has already amortized, ordered by competência, which is the amortization table's own key order. 'origem' on each amortization is the provenance a reversal acts against: E1 is an amortização prevista, which nothing withdraws, and E5 is an antecipação, which its own exclusion can withdraw. That distinction is why the two are published rather than collapsed into a count. An obligation with NO amortization at all answers an empty list and never a 404. The obligation is real and has simply never amortized, which is the ordinary state of a contract in its first month. It answers from a LOCAL table and never reaches the Dataprev rail. The tenant is derived from the validated identity: a contract that does not exist and a contract belonging to another tenant are the SAME answer, 404, so this read cannot be used to probe another tenant's book. ## OpenAPI ````yaml /en/openapi/v3-current/consignado.yaml get /v1/consignado/contracts/{numero_contrato}/saldo-devedor openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- OpenAPI 3.1 surface for Lerian Consignado — Dataprev.
