RBAC: connectivity:admin. The tenant is ALWAYS taken from the validated request context, never the path. The REST rail is functional; a managed file-transfer or message-broker transport is not currently available and returns 503. A non-QUEUED operation returns 409 INVALID_STATE_TRANSITION with currentState + allowedStates=[QUEUED]. ## OpenAPI ````yaml en/openapi/v3-current/slc.yaml post /v1/connectivity/operations/{id}/retransmit openapi: 3.1.0 info: description: >- API for Lerian SLC — the participant-side rail that connects the institution to Núclea's SLC deferred-net card settlement.
