This lists those cycles, most recent first, each openable with the report's ?cycleId=, from the detection to the close, or to now while it is open. A cycle that completes while the close commits may also be listed on the finding opened after it. ## OpenAPI ````yaml /pt/openapi/v3-current/jd-courier.yaml get /v1/channels/{channelId}/reconciliation/findings/{findingId}/cycles openapi: 3.1.0 info: contact: email: support@lerian.studio name: Lerian Studio Support description: >- The JD Courier API. Operators use it to manage the engines, the ownership map, the rails and their delivery modes, the retained messages, the SPB send journal and reconciliation.
