CMN 4.966 art. 49) with money the borrower paid later, in one transaction; the contract stays written off. The money first pays the written-off amount W, untaxed, and releases the write-off control by that part; what exceeds W is new revenue, taxed by PIS/COFINS (Lei 9.718 art. 3 par. 2 II). An amount above the remaining debt is refused (LENDER-0979) with remainingDebt. The recovery is dated by receivedAt, which must not be before the instant of the write-off nor the day of the latest standing recovery (LENDER-0976): recoveries are recorded in money order, so the split and the tax fall in the right month; a recovery that was reversed no longer counts, which is the way out of an out-of-order day. Keyed on X-Idempotency alone: the same key with the same amount and receivedAt replays the recovery and moves nothing; the same key with another body is refused (LENDER-0978). ## OpenAPI ````yaml /en/openapi/v3-current/lender.yaml post /api/v1/br/loan-accounts/{id}/credit-loss-recoveries 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.
