FULL-REPLACEMENT: the body carries the entire set (1..100 responsáveis), never a partial update. The submission is persisted with status SUBMITTED before dispatch; BACEN's GEN0019R1 acknowledgment confirms it via NUOp correlation. Idempotent — replaying the same X-Idempotency key with the same body returns the cached response. ## OpenAPI ````yaml en/openapi/v3-current/spb.yaml post /v1/str/responsibles openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- OpenAPI 3.1 surface for Lerian SPB, the direct integration between the institution and the Brazilian Payment System (SPB) over the National Financial System Network (RSFN).
