The client declares the advisory + instruction it settles, the SILOC traceability (echoed as the command NumCtrlIF), the positive money magnitude, and the explicit DEBIT side; the platform SERVER-DERIVES the wire ISPBs (funding IF + SILOC câmara), the OT product, and the movement date — none are client-supplied and none is reconstructed from the advisory. The command is persisted idempotently and its signed LDL0022 frame is enqueued for STR dispatch in the same transaction. This means dispatch was accepted, not SILOC settlement confirmation; the outcome arrives asynchronously on the LDL0022R1 leg. Idempotent — replaying the same X-Idempotency key with the same body returns the cached response. Lerian SPB EMITS the deposit-command fact + correlation and routes settlement; it holds NO SILOC position. ## OpenAPI ````yaml /en/openapi/v3-current/spb.yaml post /v1/str/operations/ldl-deposits 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).
