Identity is the file's CONTENT: the same file re-uploaded is inert and reduces no debt twice. The file's own header names the agent, and a file this tenant cannot attribute to anybody — neither its active channel nor an agent still holding an open instruction — is refused before a single line is stored. Accepting the file applies nothing: each line becomes durable work, applied independently, so one unrecognised instruction is quarantined for an operator instead of blocking every other borrower's payment in the same upload. A line declaring a receipt the agent cannot have taken yet — a paid instant more than a few minutes ahead of the moment we receive the file — is refused too, and refuses the whole file: that instant is the ACCOUNTING instant of the settlement, so a skewed clock or a broken date formatter would book a repayment in the future. ## OpenAPI ````yaml /en/openapi/v3-current/lender.yaml post /api/v1/br/consignado/collection-settlements openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- Code-first OpenAPI 3.1 surface for the Lender service.
