The owner is always the caller: an engine claims for itself and can write nothing else to the map. ## OpenAPI ````yaml /en/openapi/v3-current/jd-courier.yaml put /v1/ownership/recurrences/{recurrenceId} openapi: 3.1.0 info: description: >- The JD Courier API. Operators use it to manage the engines, the ownership map, the delivery modes and bypass of each rail, the retained messages, the SPB send journal and reconciliation.
