The request carries a `reason`. Closing records the closure on the case and appends an `operator_case_closure` record to the evidence trail. A case that is not open returns `404` with code `SRC-0301`. ## OpenAPI ````yaml /pt/openapi/v3-current/src.yaml post /v1/src/operator/orphan-responses/{caseId}/closure openapi: 3.1.0 info: description: >- API for Lerian SRC, which sends your institution's restriction consultations to BACEN's BC Protege+ and keeps the evidence of each consultation. title: Lerian SRC API version: 1.0.0 servers: - url: https://api.example.com description: Replace the example host with your deployment's address. security: - m2m: [] tags: - description: >- Asynchronous restriction consultations (accept → pending → completed/failed). name: consultation - description: >- Client-decision records (exceptional proceed, refusal explanation) — single-purpose, write-once. name: decision - description: Regulatory evidence trail — search, reconstruction, chained correction. name: evidence - description: Aggregated numeric view per institution. name: dashboard - description: Status of the institution's regulatory credential. name: credential - description: >- Operator cases — the backlog `openOperatorCases` counts, and the act that closes one. name: operator paths: /v1/src/operator/orphan-responses/{caseId}/closure: post: tags: - operator summary: Close an orphan-response case description: >- Closes an open `orphan_response` operator case: an inbound message that matched no operation of this deployment.
