A prior fund attribution alone does not open fund-scoped reads. The bancarizador identifies the credit with the idempotency_key used for the bid and the fund that signed the endosso. The credit must already be attributed to that exact fund; a credit without an attribution or attributed to another fund is rejected. The operation is idempotent. Registering the same credit and fund again returns the durable state instead of creating a second row or feed fact. cedido starts false and becomes true only through this registration. ## OpenAPI ````yaml en/openapi/v3-current/consignado.yaml put /v1/consignado/leilao/bid-submissions/cessao 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.
