The PENDING row commits with its frame, so a failed submit leaves neither. The response is an acceptance, never a settlement: the state comes from the BACEN answer (SitLancRCO) and from nothing else. Idempotent — the X-Idempotency key lives with the movement: the same key and parsed request (member order and whitespace do not count; any other difference, such as number spelling, null for an absent field, or an unknown member, is another request) answer the stored movement with X-Idempotency-Replayed: true, also after X-TTL has dropped the cached response, and the same key with another request answers 422. The amount is forwarded verbatim; no compulsory position is computed or held. ## OpenAPI ````yaml /pt/openapi/v3-current/spb.yaml post /v1/str/rco-movements 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).
